A certain scientific ancient martial arts warrior

"I said, why does it always feel like something is wrong?" Shangguan Yu looked at the group of people lying on the ground and stretched, "After being hospitalized for a few days, I just felt a little itchy in my hands, and now I am much more relaxed."

"You! You... You wait for me! The leader put down a cruel word and ran away with the people.

"Thank you for your hospitality, come back next time!" Shangguan Yu hurriedly shouted, "Next time there will be more people, you people are not enough for me to warm up."

Shangguan Yu looked at the sky full of stars, "It's late at night, I should go back, and I can almost go back." "

.........

"Meow~" "

Huh? What was that? Shangguan Yu, who had pointed his ears, heard a cat bark as he passed through a deep alley.

"It seems to be a cat barking." Shangguan Yu looked at the dark alley and walked in.

After a struggling sound of flipping through the box, a pair of turquoise eyes looked at Shangguan Yu. Shangguan Yu walked in and saw that it was a black cat. The dirty fur did not hide its spiritually rich eyes.

"Meow!" After a scream that could pierce the eardrum, the cat's tail exploded, and it looked at Shangguan Yu vigilantly. Shangguan Yu looked helpless, what did he do to make this cat so afraid.

After a threatening cry, the cat made an attacking gesture. Shangguan Yu looked at the cat with interest, the average wild cat will only run away when it encounters people, and there is rarely a tendency to attack people.

Shangguan Yu felt a little interested, and suddenly, the cat pounced on Shangguan Yu's face (Shangguan Yu squatted), and was grabbed by Shangguan Yu, "Little fellow, it is estimated that he has just been weaned, and he is actually so powerful." Shangguan

Yu was also taken aback, if it weren't for the quick reaction, he might really be disfigured today.

"Exactly, just worry about what kind of gift, you will send it to the door, let's go home!" Shangguan Yu suddenly showed an evil smile, originally he was not a person who loved small animals, since an "experimental subject" sent to the door, he would not let it go.

Looking at Shangguan Yu's strange eyes, the kitten shivered.

"Hey, help me prepare something..." Shangguan Yu rushed home after asking for some equipment.

By the way, I went to the convenience store and bought some cat food, and a cage. This kitten was still very hostile to Shangguan Yu, and kept attacking Shangguan Yu along the way, but after tossing for about ten minutes, he was completely exhausted and obediently carried home by Shangguan Yu.

.......

"Come, eat." Shangguan Yu carried the cat into the cage and put some cat food in the trough.

As soon as the kitten saw the food, he pounced, and Shangguan Yu wore a thick rubber glove to "desensitize the cat" to the cat.

In fact, Shangguan Yu does not know whether this will work or not, after all, this training is used to train police dogs, and desensitization training interferes with pets when they eat, so that they are accustomed to external harassment and become less sensitive. This is to use animals when eating, will produce a strong protective psychology, to anyone close will have an aggressive desire, as long as they continue to interfere when they are young, let them get used to it, so that there will be less aggressive behavior.

This is why many pet dogs often bite people, but cats don't seem to be so particular about this, but this cat is going to send Mikoto Misaka, who is Mikoto Misaka, and the magnetic field emitted unconsciously around can make all animals go around, especially sensitive creatures such as cats.

Although a certain Misaka sister took care of a cat in the original work, the strength of Misaka sister is average at level 2, can the magnetic field emitted by level 2 be compared with level 5? So Shangguan Yu conducted anti-interference training on this cat.

The cat saw two big hands carrying itself away from the food trough, and immediately exploded and bit towards the rubber glove.

"Newborn calves are not afraid of tigers, normal cats should already be trembling, this one actually dares to fight back." Shangguan Yu secretly exclaimed and smiled, "The vitality is really tenacious - but fortunately, it is not easy to be tossed to death by me." "

.......

"Ding-dong!" A doorbell rang.

Shangguan Yu, who had just gotten up and was brushing his teeth, rinsed his mouth and went to open the door.

"Oni~Sauce" opened the door, and Shangguan Xuefei pounced.

"Why don't you have to go to the institute today?" Shangguan Yu asked.

"It was originally good, but suddenly the research progress was stuck, and I stayed there and had nothing to do, so I came over." Shangguan Xue explained, and then pointed to a box outside, "Also, what do you want this thing for?"

"You'll find out later." Shangguan sold a pass and began to unpack.

The box is a gun-like thing, but the front end is ring-shaped, and there is an iron box. Shangguan Yu took out the gun, connected the rear wire to the iron box, and plugged in the power supply.

"Hmph!" The corners of Shangguan Yu's mouth rose, like a mischievous child, looking at the little cat still sleeping in the cage, "Unlucky child."

"Hey, what are you going to do?" Shangguan Xue had a bad premonition.

........

"Meow!!!" The kitten suddenly exploded and jumped up, knocking the cage over, and the whole tail was like a mace, and the hair looked like it could be pricked.

I saw Shangguan Yu holding the gun, facing the cat, and the other hand was still adjusting the knob on the box.

"What are you doing, brother, this cat is so pitiful." Shangguan Xue unplugged the power supply and took the kitten out, and the originally irritable cat immediately quieted down.

"Brother, what did you do to it? Why are you so scared? Shangguan Xue looked at those pitiful turquoise eyes and said angrily to Shangguan Yu.

"Uh-uh, it was last night..." Shangguan Yu repeated what he had done last night.

"No way, you're lying to me! Just like that, it's just anger, not fear. Shangguan Xue stared at Shangguan Yu deadly, "What else have you done!"

Now it was Shangguan Yu's turn to be stunned, "Isn't it, I did this?" "

Really?"

"Really!"

"Well, believe you." Shangguan Xue looked at Shangguan Yu as if he was lying, and decided to use his own method to obtain information. After speaking, he began to sense the cat's emotions.

"Don't you believe me so much?" Shangguan Yu said helplessly, sitting next to him and watching Shangguan Xue and the cat look at each other.

A special serene spiritual fluctuation unfolded, and Shangguan Yu inexplicably felt a burst of peace, "It's so comfortable, I feel that the whole person has been purified." Shangguan Yu was not the first time to contact this, but every time, he couldn't help but relax wholeheartedly.

"Indifference - darkness - killing - death - and..." Shangguan Xue felt as if she had transformed into a cat, and saw Shangguan Yu's inexplicable appearance of these words.

Shangguan Xue found out that this cat was not ordinary, and it could partially dock her mental fluctuations, but why was his brother related to those words?

When he continued to feel the cat's emotions, he found that Shangguan Yu was like a demon in his eyes.

"It seems that my brother still has a bit of a 'little secret'." Shangguan Xue thought.

"What's wrong?" Shangguan Yu saw that his sister was stunned, and quickly cared.

"It's nothing, it's just a little too consuming." Shangguan Xue waved his hand, "There is one thing, can I ask you."

"What's going on?" Last time I didn't promise you one thing, as long as it wasn't too much.

"I..... I wonder what happened to you. "

“........ The one who should come is still coming. Shangguan Yu sighed silently, in fact, at one or two o'clock in the morning, Shangguan Yu received a call from Lin Long, saying that he found that something was wrong with Shangguan Xue, probably because the crystal itself is a collection of negative emotions, may be affected by it, Shangguan Xue's heart demon broke out in advance, and the researchers' psychology also had some abnormalities, so let Shangguan Xue out to relax, let Shangguan Yu know more.

Shangguan Yu immediately thought that he had killed the red eye on the battlefield for a while, and came out with a murderous aura, which scared Shangguan Xue, and now it seems that the heart demon may have been planted at that time.

"Alas! You still have to fill the pit you dig yourself! Shangguan Yu sighed in his heart.

Shangguan Xue a few years ago, found that Shangguan Yu was wrong, especially those eyes, sometimes exuding killing intent as if he would kill himself, although it was only fleeting, he himself did not seem to notice it (Shangguan Yu himself thought that it was just once, in fact, the killing intent inadvertently revealed could drive a child crazy), but later this strange phenomenon became less and less, Shangguan Xue thought that it was just his own illusion, so he buried it in his heart. (Shangguan Yu was prone to this kind of thing when he used Toye Lake at the beginning, and later Shangguan Yu actually discovered his sister's abnormality and decided to slow down the number of times he entered the battlefield)

As everyone knows, such a heart demon came quietly, until today, Shangguan Xue learned through the perception of cats that what he felt at that time was not an illusion, and at the same time, he also discovered the inner demon in his heart.

After Shangguan Xue's cultivation has advanced by leaps and bounds in a few years, he has slowly stepped into the current realm, and a large reason is because of this heart demon. The next is about to cross the calamity, if he does not solve the heart demon as soon as possible, Shangguan Xue can imagine his final miserable situation.

“....... Well, then use your method to get what you want to know. Shangguan Yu said with a smile.

Shangguan Xue has a heart demon, Shangguan Yu also has a heart knot, although this does not affect the improvement of strength, but it is always uncomfortable, although Shangguan Yu received memories before the age of eleven, but inexplicably there was such a layer of separation from the world

, until -

until that shot, a year or two ago, a certain post office in the school city was robbed, Shangguan Yu happened to be on the scene, looking at the letters from his family (ordinary greetings and concerns, confidential events with computers), I didn't notice the robber for a while (how big is your heart!). ）。 It wasn't until the isolation door was lowered that Shangguan Yu noticed.

Then Shangguan Yu was ready to strike, but found Hatsuharu Shirito and Shirai Kuroko, who did not know each other at that time. So Shangguan Yu planned to watch first, and at the moment of Shirai's black son, when Shangguan Yu was ready to strike, an electromagnetic cannon blasted over, directly shattering those steel balls. At that moment, Shangguan Yu was really shocked, and at the same time, Shangguan Yu had a little familiarity with the world.

........

Shangguan Xue stared at Shangguan Yu's eyes deadly, and a different spiritual fluctuation appeared than just now. This skill was originally used to cultivate the mind, by reviewing one's own memories and improving one's state of mind, but if others do not resist, to a certain extent, you can see the memories of others.

Therefore, Shangguan Yu also wanted to truly live his first eleven years of life through this method.

Shangguan Yu and Shangguan Xue seemed to have entered a special world.

"Not good! The heart demon started at this time! Shangguan Xue suddenly sensed something and showed a worried expression, "Oops, I didn't remind my brother, he shouldn't sink."

"If you know that the heart demon appears, you will be more or less mentally prepared and remind yourself that this is false, but my brother does not know and has never understood this knowledge, and it is very likely to be invaded by the heart demon."

But has anyone told me what it's like for my own demons to invade other people's hearts?! What happens if a non-Truth Cultivator is invaded by a heart demon?! Online wait, urgent! "
