I’m Upgrade by Selling Moe [Interstellar]

This little cutie~ Since your subscription ratio is not enough, the anti-theft badge is displayed~ Three humans dressed as hunters came over carefully. They held the weapons in their hands tightly and observed their surroundings.

Among them, the man in gray clothes frowned, "The mutated beast seems to have run away. I guess it must have discovered us."

"Then let's chase it quickly, maybe it hasn't gone far yet." Another person said.

The man in gray noticed the tree that was split into half and analyzed: "Then we will split up and chase each other. If we catch up, we will send out the signal flare immediately."

The remaining two people nodded in agreement. In order to hunt down the mutant beast as quickly as possible, the three of them did not waste any time and words, and immediately chased each other separately, without noticing the huge boulder in the corner.

Ji Wuxiu breathed a sigh of relief and subconsciously glanced at the Black Panther.

The black panther's vertical pupils contain coldness, but not madness.

Since the mutation, it is no longer the black panther that only took revenge stupidly and did not evaluate the pros and cons of danger.

The black panther flicked his tail and growled lowly.

"Roar——" Ugly creature, let's go.

Ji Wuxiu was stunned for a moment, said nothing else, and nodded in agreement.

As the days passed, Ji Wuxiu quickly forgot what happened that day. Until today, the black panther went out hunting, but it still hadn't come back in the afternoon.

Ji Wuxiu was restless, always feeling something was wrong.

Suddenly, a ball of black fur crawled into the doorway of the tree hole. The hair on its body seemed to be singed, and it made a shrill chirping sound.

"Jiji!" Something happened to the black monster!

Ji Wuxiu panicked and quickly pulled the black fur ball over to question him.

The black fur ball kept rolling nervously, and finally expressed the matter clearly in a few words.

It turned out that the black panther went out hunting today and planned to catch a rabbit and bring it back, so the black fur ball naturally followed him.

Unexpectedly, they met three humans on the way. The weapons in the humans' hands could spit fire and caught the black panther. The black-haired ball was petite and had talents focused on escaping. Then he hurried back and reported the letter.

Ji Wuxiu's mind went blank, and he suddenly remembered the three people he met a few days ago.

This is troublesome.

Ji Wuxiu quickly asked the black fur ball to lead him through the woods and walked for a while.

"Chichi!" The black fur ball bounced a few times, indicating that the destination was not far away.

Ji Wuxiu asked the black fur ball to hide here and not move, while he quietly touched it to judge the enemy's situation.

Not far away, more than half of the black panther's shiny fur was scorched. It seemed that it was not seriously injured and it was still roaring vigorously.

While Ji Wuxiu was relieved, he couldn't help but be surprised.

The three men surrounded the black panther tightly, throwing fiery snakes out of their hands and throwing them at the black panther.

Even awakened supernatural beasts still have an instinctive fear of fire.

The Black Panther didn't dare to resist, so he could only rely on his agility to dodge, and from time to time he would use his lightning powers to attack humans.

But it's a pity that humans have been prepared for it and quickly used supernatural powers to resist it.

For a moment, the three of them and the leopard were deadlocked in place, and no one could do anything to anyone.

When Ji Wuxiu saw this, he was anxious and in a dilemma.

He evaluated the combat effectiveness of these three people and felt that he was unable to fight head-on.

Seeing that his attacks failed repeatedly, the leopard roared angrily and made sneak attacks from time to time, eager to tear the human alive into pieces.

After several rounds, the situation was still deadlocked, but the tip of the leopard's tail was accidentally burned off.

The leopard became more and more angry and roared: "Ouch!"

——Damn humans, my furry——Ouch!

Ji Wuxiu twitched the corner of his mouth and almost coughed.

The anger made the leopard become angrier, and its powers became stronger each time. Soon, some wounds gradually appeared on the three people.

Ji Wuxiu's eyes lit up and he quickly used [The sound wave is too strong and will hit the ground if it doesn't shake] on the three people.

In the blink of an eye, the three of them were immediately dizzy, and the world in front of them was spinning. They covered their heads with pain on their faces, and fell to the ground in embarrassment.

Within a few seconds, the three of them could no longer hold on to this feeling and started vomiting wildly.

Ji Wuxiu then popped up and waved to Black Panther.

The black panther ran over, flicked his tail quickly, and shouted nervously: "Ouch!"

——Ugly creature, let’s run!

When Ji Wuxiu was about to nod, the system that had not spoken for a long time suddenly prompted: [Ding! It is recommended that the host stays and uses your appearance to earn points. 】

Ji Wuxiu was stunned and stared at the three people, feeling a little moved.

[Ding! If danger arises, you can also use skills to escape. 】

Ji Wuxiu only hesitated for a second, and then decided to do as the system said. Then he quickly dragged Black Panther away and hid in the dark, then asked Black Panther to leave for now and hide so as not to appear.

Black Panther stared at Ji Wuxiu closely and howled.

——What about you, ugly creature.

Ji Wuxiu touched Black Panther's head and called out a few times.

——I want to stay here.

The leopard's eyes suddenly widened and he shouted at Ji Wuxiu: "Ouch!"

——Ugly creature, are you crazy?

Ji Wuxiu was very moved, but he couldn't really leave. After all, he finally encountered a human being and had to earn points quickly.

The Black Panther, who didn't know the truth, shook his head desperately.

The ugly creature is so weak, it will die if left here.

Ji Wuxiu's eyes widened, he slapped Black Panther's head and shouted, "Ouch!"

——You have to listen to me, understand, otherwise there will be no rabbits to eat in the future!

The Black Panther shrank his head in frustration and roared feebly: "Ouch——"

Ji Wuxiu then nodded with satisfaction, patted the black panther on the head, and shouted: "Ah, woo?"

——From now on, you will listen to the boss, you know?

Black Panther tilted his head, looking confused, "Ouch?"

——What is the boss? Is it delicious?

Ji Wuxiu slapped him again and yelled: "Ah! Woo?"

——Fuck you, boss, from now on you have to listen to me, eat from me, and be an obedient little brother, do you understand?

After the Black Panther finished digesting this passage, he flicked his tail and focused on something else.

"Ouch-ouch-ouch?"

——As long as you obey, you will have meat to eat?

Ji Wuxiu twitched the corner of his mouth, and under the particularly expectant eyes of Black Panther, he said firmly: "Yeah!"

The Black Panther was instantly satisfied and left. After walking a few steps, he seemed to remember something, turned his head and let out a cry.

——Boss, I’m leaving!

Ji Wuxiu waved his claws, his face hurt.

******

Over there at this time.

The five seconds of cd time had long passed, and the three people finally recovered, but their faces were full of fear and vigilance. They constantly looked around vigilantly, and then breathed a sigh of relief after making sure there was nothing strange.

"What's going on?" The man in gray suppressed the shock in his heart and said with lingering fear.

Just thinking about the dizzy feeling just now made him want to vomit.

"No, the leopard seems to have escaped." One of them suddenly said in shock.

The three people got up quickly and did not choose to search because they were afraid of encountering such a feeling again.

"Maybe it was the leopard who did it!" one of them suddenly guessed.

The other two people also thought it made sense.

After finding the culprit, most of the fear in the three people's hearts disappeared instantly.

"Damn it, you must catch it." The man in gray said with a stern expression.

When Ji Wuxiu heard this, he was a little glad that he let Black Panther leave.

[Ding! Host, please don’t be careless! I'm optimistic about you! 】

Ji Wuxiu came back to his senses, nodded, and took a deep breath.

He must perform well next and work hard to earn cuteness points.

******

The three of them briefly discussed for a while and decided to expand the search area nearby and catch the nasty leopard.

And at this moment... there seemed to be a commotion in the tall bushes in the corner, as if there was something living inside.

The three of them immediately became vigilant, approached cautiously, and then prepared to attack.

However, when they opened the bushes, their expressions suddenly became stunned.

What the hell is this fur ball? ! !

In the grass, a black and white creature that was as fat as a ball was also startled and raised its head suddenly.

The three of them stared wide-eyed again: This thing actually looks so strange.

The black and white creature had dark circles on its face. It looked sad and troubled. The words "chubby and cute" were written in big letters everywhere on its body.

The three people looked shocked: What kind of creature is this? !

The black-and-white furry ball gathered itself up silently, with a sad expression on its face, and made a thin cry.

"Ah woo~"

When the three of them heard this childish and coquettish voice, they couldn't help but trembled, and their minds went blank.

【Ding! Your cuteness was so natural that the three humans were so shocked that they were speechless and thought, "How could there be such a strange-looking yet cute creature in this world?" You gained +9 cuteness points. . 】

Although it sounded nondescript, like humming.

It looked left and right, scratched its belly, and its thick flesh trembled.

The breeze blew through his hair, and the coolness everywhere made him feel very happy. His face was full of energy, but he still looked aggrieved and frustrated.

After a while, Mr. Panda's expression gradually became serious. He looked left and right again, as if searching for something, and finally said seriously to the system: "System, I think I should eat."

The system seemed to be silent for a while: [Host, you have to solve this matter yourself. You are no longer the same person as before. You can now solve all problems by being cute. 】

Mr. Panda looked astonished and rubbed his chubby belly even though he was hungry.

It was a mistake, and I almost forgot that now I can rely on my face to make a living.

The system seems to want to encourage the host, saying: [Work hard to accumulate cuteness points. There are many good things in this system waiting for you to redeem them. 】

Ji Wuxiu suddenly asked curiously: "What good things are there?"

The system brought up a translucent virtual screen and showed it in front of Ji Wuxiu, indicating to him to look at the numerous products inside.

【Ding! Host, have you seen it? As long as you show more cuteness, you can buy whatever you want. The winner of Xiongsheng will definitely be you in the future. 】

Even though the system's voice was as unpassionate as ever, Ji Wuxiu was very excited when he heard it. He had seen clearly just now that the products in the system were unheard of, and there were almost all kinds of products.

It’s just that all of this needs to be exchanged for cuteness.

Clenching his furry paws into fists, Ji Wuxiu let out a determined hum, and the panda's eyes shone with hope for the future.

——Everything is for the sake of cuteness!

******

The creature lying on the tree slowly stood up and licked its mouth. It stretched its body, raised its butt slightly, and flashed its claws. Finally, it slowly adjusted its posture by twisting its butt and preparing to attack. posture.

It had been looking here for a long time, and easily judged that the ugly creature was not threatening.

Most importantly - the prey looks ugly.

It sneaked slowly, licking the corners of its mouth out of nervousness, revealing its sharp teeth that shone with cold light. The dim sunlight fell on its shiny fur, reflecting a faint halo.

Suddenly - it burst out from the dense leaves and jumped in the air, with some broken branches and leaves scattered around.

Under the sun, its fur is black and shiny, without a trace of impurities, and its smooth body is full of vigor and lethality that cannot be ignored.

——It fully illustrates that this is a Black Panther who is healthy and in peak condition.

Mr. Panda, who was leaning on the tree trunk, heard the roar and raised his head in fright. He witnessed the shocking scene of the black panther leaping out with his own eyes.

——It’s a leopard!

Ji Wuxiu's eyes widened, and he noticed that the black panther was coming towards him. It still didn't understand what was going on, so it got up with a roar and ran away in a mess.

The black panther landed lightly, its flesh pads hiding all sounds, its vertical pupils staring closely at the strange creature, and it couldn't help but shake its beard.

——So ugly

Then, the black panther quickly chased after him, his smooth figure was like a forest elf, and his every move was full of violent beauty.

Ji Wuxiu was running forward in a haphazard manner, burrowing into trees where there were many in an attempt to stop the Black Panther from approaching.

While running, Ji Wuxiu screamed.

The hair was fluffy because of fear, and the big round butt was very conspicuous in the green forest.

"System! System! What should I do!" Ji Wuxiu's scalp was numb, and he called out to the system in his heart in fear.

【Ding! Host, your body is personally built by the system. Even though you are just a rookie who has not yet upgraded, you are not an animal that can be killed. What’s more, you can conquer this black panther by being cute! 】

Ji Wuxiu's eyes lit up when he heard that, yes, why didn't he think of it before?

The black panther roared, sped up its running speed, and nimbly crossed an obstacle. Finally, it spotted its prey and swooped over, holding down the apparently plump and delicious prey with one paw.

There was a bang, and a force of gravity made Ji Wuxiu instantly collapse into a large figure. He couldn't get up, so he could only dance with all his limbs and scream in fear.

"Ouch!" Help! The leopard is going to eat the bear! !

Just thinking about the fact that there was a black panther on top of him made his scalp tingle and the fur inside stood up!

Bear's paw subconsciously exerted force and slapped the black panther.

--Slap me!

The black panther's face hurt, then he realized something and quickly roared at this ugly prey!

"Hoo-ouch!"

The roar seemed to stir up a weak wind, blowing Mr. Panda's fur into a mess. It shook spinelessly, and its drooping eyes were filled with fear.

It's so... so scary.

[Host...I let you act cute...I didn't ask you to beat it. 】

Even at this moment, the system, which had always been calm in tone, could not help but feel a little speechless.

How could the trembling Mr. Panda admit that he only heard the first sentence and forgot the second sentence?

"No... I'm sorry, I'm too nervous."

[This system is upgraded by me acting cute. It is not like other krypton gold systems that upgrade with 999 for a single cut, nor is it a system where you have to search everywhere for heaven, material and earthly treasures to practice. We only need to act cute and act coquettishly to conquer the world. You... …Why can’t I be satisfied? 】

After being scolded, Mr. Panda lowered his head, feeling ashamed. He deeply reflected on his mistake and decided to listen to the system and show off his cuteness to the black panther.

The black panther was still very angry, staring at this ugly creature,

The system reminded: [Host! It’s time for you to be cute and conquer it. 】

Ji Wuxiu racked his brains and thought for a while, and finally made a soft sound in an attempt to reduce the Black Panther's aggression.

The black cat lowered his eyes and looked at the prey coldly. He pressed it again until his claws were buried in the bear's fur, and made a shocking sound, "Ouch!"

It hurts...

Ji Wuxiu screamed, his chubby limbs flopping awkwardly.

Tears are about to fly out.

The black panther licked his mouth, a little confused.

In the past, it only needed to open its mouth and bite.

But now it's a bit troubled, not knowing where to bite.

Because this creature is ugly everywhere and hard to eat.

Ji Wuxiu's face was so painful that he couldn't help but let out a quick cry.

"I'm going to die, system! I really feel like I'm going to die."

The system was silent for a while, seeming to feel sad that it had such a stupid host, and its tone became a bit hateful: [Host, do you still remember what you are best at? 】

Ji Wuxiu's eyes were blurry with pain, and he hesitated: "Is it... drinking and playing cards?"

The system fell silent again, then raised its voice: [It's so cute! What you are best at should be being cute! 】

Ji Wuxiu couldn't help but let out a sad cry, "I understand!"

Why does it always forget its own advantages!

[Okay, host, next you must try your best to be cute with this leopard. This is your first order in the life of a panda, so you must do your best to be the best. 】

Ji Wuxiu became nervous at the system's words. He quickly searched for the giant panda videos he had seen in his memory, recalling the cute and cute tricks of the national treasures.

At this moment, the black panther gave up the struggle and decided to take a casual bite.

Ji Wuxiu quickly moved his buttocks, trying to express his desire to turn over.

Black Panther looked on with cold eyes and decisively refused.

Too ugly.

Ji Wuxiu didn't know why Black Panther refused, but it had no choice but to follow the video in its memory and try to make a soft sound.

"Meow~woo~"

At the same time, he also tried his best to turn his head, winked at the black panther, and showed a cute smile.

The black panther, who was watching coldly, widened his eyes, straightened his neck and stiffened his body.

Ji Wuxiu blinked, somewhat unbelievable that the effect was so impressive.

The system took this opportunity to cheer up: [Did you see it, host! This black panther has become cute for you! 】

Ji Wuxiu was inspired, and while the black panther was relaxing, he flexibly turned his body, revealing his soft belly, and performed a rolling motion for the black panther. It can be called one of the panda's special moves - roll, roll, roll!

After the performance, Ji Wuxiu was panting, but he was very satisfied with his performance just now.

Presumably, the black panther is... already trembling from his cuteness, right?

The black panther was silent for three seconds, then decisively raised its paws and kept retreating.

Ji Wuxiu stood up in a hurry, somewhat unbelievable that he had successfully escaped the clutches of the Black Panther!

The system's tone became excited: [Host! Keep working hard and make sure you earn the value of being cute. 】

Ji Wuxiu was convinced and felt that what the system said made sense.

Mr. Panda walked awkwardly towards the Black Panther with clumsy and heavy steps.

Black Panther subconsciously retreated.

Mr. Panda raised his head, his lifeless face looking as silly as ever.

Black Panther couldn't help but retreat further.

Mr. Panda moved forward again.

The black panther continued to retreat, and finally had no way to retreat. The eyes of the black panther, which looked cold on the outside, were filled with fear.

It seems to be telling you not to come over!

Ji Wuxiu drooped his eyelids, grinned with a harmless smile, and stretched out his furry little paws.

Let you touch the panda's claws and experience the national treasure's special skills.

The black panther suddenly let out a scream and rolled on the ground covering his eyes.

too ugly……

too ugly……

Ji Wuxiu was startled, took a few steps back, and asked the system with a confused look on his face: "What happened to the Black Panther?"

The system was silent, and the voice seemed filled with disbelief.

【Ding! Your cuteness makes "Lightning Leopard" feel uncomfortable. 】

[Lightning Leopard Combat Power-1]

[Lightning Leopard received a ten-second eye-searing buff. 】

[Failed to be cute, host please try again. 】

Ji Wuxiu "..."

The three of them came back to their senses and glanced at each other subconsciously, their eyes still full of residual shock.

"Do you want to capture this... thing?" one of the men in blue asked.

Although I don’t know what species it is, with such a unique appearance and natural cuteness, if it is sold on a black market exchange, it will definitely trigger a lot of people to compete for the auction.

The other two people obviously thought of this as well.

Another person glanced at the strange-looking creature from the corner of his eye. Even though he knew that the animal could not understand his words, he still whispered in a mysterious voice: "Then we will capture it and take it away." As if he was afraid of the creature. It seemed like he was scared to run away.

The other two people nodded quickly, not daring to waste time, and immediately walked around slowly, for fear of scaring the unknown creature.

After all, until now, they are not sure whether this creature is a mutant beast, what kind of powers it has, and what its combat effectiveness is.

Everything needs to be done with caution.

The man in gray slowly squatted down, and the other two quietly walked around, ready to take out the animal trap at any time. As soon as the strange creature sensed something was wrong and wanted to escape, they would immediately open the animal trap and allow it to get in. The wings are also difficult to fly.

Ji Wuxiu naturally knew all of this.

But he had never thought about escaping, so he naturally wasn't nervous. Instead, he pretended to be confused and got up slowly.

The man in gray immediately looked nervous, slowly stretched out his hand, and said as softly as possible: "Don't be afraid, I won't hurt you."

The other two people stood ready, with their hands on the animal trap, even so nervous that they stopped breathing.

Ji Wuxiu rolled his eyes secretly in his heart, but still looked confused on the surface, letting the man approach slowly until his hands gently covered the soft top of his head, and finally rubbed it a few times with slight force.

The man in gray was prepared that the creature might resist or even act aggressively.

But what he didn't expect was that instead of resisting, the furry dumpling even slowly raised his chubby arms and let out a soft cry with a cute look on his face: "Ah woo~"

The man in gray eyes widened slightly, and his heart seemed to be scratched by the childish cry.

This cry...how could it be so cute?

【Ding! Because your success makes the human beings in front of you tremble in heart and have strong emotional fluctuations, you gain +20 cuteness points. 】

Ji Wuxiu was so surprised that he couldn't help but glance at the man. He looked like he was completely difficult to get along with, and he was actually acting like a cute person. He was really beyond appearances.

The man in gray clothes had already put down most of his vigilance. He leaned over again and continued to rub the fur ball with a particularly shocked expression.

The feel of this hair... is really amazing.

【Ding! Your Maomao has successfully made the human being in front of you feel excited and think that you are so soft. You gain +3 cuteness points. 】

Ji Wuxiu silently calculated how much cuteness he had.

At this moment, the two people behind him put away the animal trap and came over cautiously. They also followed the example of the man in gray and touched Ji Wuxiu. They couldn't help but whisper: "This thing is quite cute."

The man in gray nodded and tentatively picked up the furry dumpling in front of him. The furry dumpling was very cooperative from beginning to end, without struggling or barking. He was incredibly well-behaved.

He breathed a sigh of relief and couldn't help but look at the creature.

Mao Tuanzi seemed to be aware of it and tilted his head slightly, looking back with confused eyes. The bear's paw was placed on his belly obediently, looking particularly harmless and soft.

【Ding! Your cleverness impresses the three of them, and you gain +3 cuteness points. 】

Ji Wuxiu rolled his eyes and said to the system: "How many points do I have now?"

【Ding! Your current cuteness value is: 36]

Ji Wuxiu lowered his head in disappointment. He had already tried so hard to be cute, but who would have thought that he would end up like this after a long time.

Walking to the place where he temporarily settled not far away, the man in gray put down the fur dumplings, touched his head at the same time, took out the fruit in the bag, handed it over, and said softly: "Do you want to eat?"

Ji Wuxiu took it without any grudge and started chewing it silently.

Although the panda looks harmless and cute on the outside, it is a bear after all. It can destroy most of the fruit in one bite. If you put this bloody mouth on other creatures, it can only be described as ferocious.

The panda's huge mouth only makes people feel that it is still harmless, and even a little silly.

The man in gray was stunned.

When Ji Wuxiu saw this, he thought he had frightened the man, so he immediately changed to nibbling.

【Ding! Your pure and unpretentious eating style makes the people in front of you feel excited. If you succeed in being cute, you will get +1 cuteness value. 】

Ji Wuxiu paused for a moment and raised his head, his mood was particularly difficult to describe.

There is definitely something wrong with this person's aesthetics.

The man in gray couldn't help but touched the hairy dumpling again, the corners of his mouth raised slightly, and he felt inexplicably happy.

This feeling is amazing.

You don't need to drink to numb your nerves and forget your worries. Just touching your hair can make your gloomy mood improve. With Mao Tuanzi's confused expression, all negative emotions are hidden.

After Ji Wuxiu finished eating the fruit, he couldn't help but shake out his messy hair. His body instantly became fluffy and he looked more chubby and cute.

【Ding! Your fat ball-like back made the two humans' hearts tremble, and they thought, "It looks like a ball." You successfully gained +2 cuteness points. 】

Ji Wuxiu was startled and turned his head silently. The two humans stared at him with bright eyes, as if they were marveling at how his back was so round.

Next, the three of them made a fire to cook, ate a few simple bites, and then discussed leaving the forest.

"Please be careful later and don't let it get away. Whether this order can make money or not depends entirely on it." The man in gray packed the things and did not forget to warn the two people.

"I know, don't worry." they replied.

Ji Wuxiu was a little surprised that the three people planned to leave so soon.

Just now... he gained nearly forty points of cuteness from these three people.

Until now, he still feels a little unsatisfied. The feeling of being able to reap the cuteness value just by sitting motionless is very wonderful.

The system seemed to sense Ji Wuxiu's dangerous idea of ​​getting something for nothing, and immediately said: [Ding! Host, your idea is very dangerous. You have to understand that a situation like today can only happen once. After all, no matter how cute a creature is, it will develop immunity after being seen for a long time. You have to keep working hard to study the skills of being cute. 】

Ji Wuxiu nodded and couldn't help but ask: "If I keep acting cute to a person, as time goes by, the value of being cute will become less and less. What should I do then?"

The system said calmly: [So this system recommends that you purchase related cuteness skills. 】

Ji Wuxiu was stunned and said, "Why didn't you tell me this?"

【Ding! This skill can only be unlocked when you reach level one. After all, pandas without the talent of being cute are not eligible for better skills. 】

Ji Wuxiu: "..."

Well, so far, he only has 39 points of cuteness points, and he is still far away from 100 points.

Ji Wuxiu was so depressed that he wanted to drink and play cards. When he caught a glimpse of the three people's packages from the corner of his eye, he couldn't help but be startled.

That is?

Ji Wuxiu quickly went over and took a sniff, his eyes suddenly brightened. The liquid in the bottle was definitely wine, especially the smell of wine wafting out of it. It was so strong that it made his mouth water, and the alcohol content was definitely very high.

Seeing this, the man in gray quickly pushed Mao Tuanzi's head away, "You can't touch this thing."

Ji Wuxiu sneered, it wasn't just strong alcohol, as if no one had ever drunk it. But on the surface, he still maintained a well-behaved and ignorant face. He pretended to be interested and rummaged through his backpack, but in fact, he was looking at what good things there were. .

In addition to wine, there were also some technological products that he couldn't understand.

Ji Wuxiu looked confused and could only give up.

The backpack was disturbed, but the man in gray was not angry. He packed the things again and buttoned them up. "Go out from there in a moment and send this animal to the black market exchange quickly."
