Surprise! The little sister who is loved by the group is actually the strongest in Kyushu!

"A-choo! Ah, what, what do you mean, it's clearly... A-choo, that's it!"

Qi Fanfan sneezed several times in a row.

Qing Jiujiu frowned strangely and looked up at the sky.

"Could it be that old man Tiandao is making trouble again?"

"Who knows?"

"However, if he doesn't make trouble today, he will make trouble tomorrow. My master and his friends are setting up a formation. Although my master and his friends have become stronger, if old man Tiandao comes again, they will not be able to deal with him alone." Qing Jiujiu touched her chin and looked at Qi Fanfan, her eyes full of hints.

Qi Fanfan understood what Qing Jiujiu meant.

She wanted him to help set up a formation that could defend against old man Tiandao.

"I do know one thing. Do you remember the 'Klein bottle' that Dad told us before?" Qi Fanfan said.

Qing Jiujiu's eyes lit up slightly, and she instantly understood what Qi Fanfan meant.

She snapped her fingers and whispered, "Non-orientable closed surface! There is a hole at the bottom of the bottle. The neck of the bottle is extended and twisted into the inside of the bottle, and then connected to the hole at the bottom. Unlike the cups we usually use to drink water, this object has no "edges", its surface will not end, and it is not similar to a balloon. A fly can fly directly from the inside of the bottle to the outside without passing through the surface (so it has no distinction between inside and outside)."

Klein bottle structure

"As long as we use fairy energy to make such a barrier outside the Qianyuan Fairyland, all attacks from the outside world will be like this "fly", unable to enter the Qianyuan Fairyland and fly out directly?"

Qi Fanfan nodded, walked to the window with his hands behind his back, pretending to be unfathomable.

"Not bad! In this way, no matter how big the attack of the Heavenly Dao is, it cannot enter the Qianyuan Fairyland. However, this thing is a bit difficult to make. Even if the mathematician makes this diagram, he has to draw it..."

Qi Fanfan turned around and there was nothing behind him.

"Jiujiu?"

"Hey? Where's the person? How come he disappeared while talking peacefully?"

Qi Fanfan touched his head.

Suddenly, someone outside the window called out.

"Look! What is Lord Xuanhuang doing in the sky?"

"It seems he is setting up a barrier."

"Wow! Such a strong fairy spirit!"

Qi Fanfan: ? ? ?

He walked back to the window with some suspicion, half of his body leaned out, and saw Qing Jiujiu flying around quickly outside the Qianyuan Fairyland. In just a few seconds, a 'Klein bottle' composed of fairy spirit appeared.

Qi Fanfan opened his chin slightly.

This...

This is too abnormal. This kind of thing was actually made just as it was said!

Qing Jiujiu, is this guy still human? !

Qi Fanfan twitched his lips. When he was bored in Jiuzhou before, he thought of this thing. It took decades of research to make it with spiritual energy. He was thinking about pretending to be cool.

Qing Jiujiu clapped her hands and flew down from midair.

"Okay! Now, no matter how strong the attack from outside is, it will be like entering a loop space and cannot harm Qianyuan Fairyland."

"Let's go and find the core code!"

Qi Fanfan was still standing there in astonishment.

Qing Jiujiu saw that he didn't react, so she patted his shoulder.

"Hey, what's wrong with you?"

"No, nothing."

Qi Fanfan swallowed and pointed to something in the sky.

"How did you... make it?"

"Is it difficult? My father told me before, and I did it with computer 3D modeling. Now it's much easier to do it directly with fairy energy than with a computer."

Qing Jiujiu said disapprovingly.

Qi Fanfan groaned and felt a pain in his heart for no reason.

"Let's go." Qing Jiujiu urged again.

Qi Fanfan nodded: "Yes."

Qi Fanfan stepped on the tiptoes and prepared to fly, but suddenly remembered something and fell down again.

"By the way, you made a barrier, how can we get out?"

Qing Jiujiu frowned and looked at Qi Fanfan in confusion: "What? Your system didn't give you 'instant'?"

Qi Fanfan: ...

Well, my heart hurts even more.

"It's not true?" Qing Jiujiu blinked.

"Yes, yes, no." Qi Fanfan smiled and looked at Qing Jiujiu like a big enemy.

Could it be that the things given by the system are all different?

Qing Jiujiu sighed in her heart, and then grabbed Qi Fanfan's arm: "It doesn't matter, I'll take you away."

Her figure flashed.

The two came to the universe outside the Qianyuan Fairyland.

Qi Fanfan was even more shocked. He could bring people to instant, and he could play like this?

Absolute! My parents are so awesome! They gave all the good stuff to Jiujiu!

In one word, awesome!

The two of them were ready to continue.

Suddenly, a strong forceThe strong immortal energy came from far away and quickly approached Qianyuan Fairyland.

Qing Jiujiu's movements paused and she looked at Qi Fanfan.

"Do you feel it?"

Qi Fanfan nodded and groaned: "Yes, I feel it."

In the void, there were many fallen fairyland fragments. The two of them found a piece of rubble and hid behind it.

The powerful immortal energy was getting closer and closer, and more than 30 masters appeared outside Qianyuan Fairyland.

At a glance.

The information of more than 30 masters flashed in front of Qing Jiujiu's eyes.

Bo Ding: Daluo Jinxian. The ultimate move breaks the Tianlong Curse.

Song Yuan: Jinxian. The ultimate move is infinite demon seal.

Yuan Qingling: Jinxian. The ultimate move is entangled holy bombardment.

Yang Hai, Ding Yun, Ji Changfeng, Shi Guozhi...

At a glance, the thirty people all have the cultivation of Golden Immortals, and the leader is a Daluo Golden Immortal, and each of them has unique skills and holds a super-grade immortal weapon.

Wait, the leader seems to have some magic weapon in his hand.

Qing Jiujiu frowned slightly and said in a low voice: "It seems that it's a good thing that you proposed to make a barrier, otherwise, with the cultivation of these thirty people, Master and others really can't deal with them."

"So what? Should we go out now and deal with these people?" Qi Fanfan said disapprovingly.

Although his cultivation has not recovered yet, he still has to talk big.

"It's okay, let's see if this barrier I made is really useful first." Qing Jiujiu stopped him and said.

Qi Fanfan nodded, and the two continued to watch the movements of the thirty people.

Bo Ding and others were suspended above the Qianyuan Fairyland, looking at the strange barrier, and pondered for a moment.

"What the hell is this?"

"It's a barrier, no matter what kind of barrier it is, with the Blood Moon Wheel, it can be broken directly, what's there to be afraid of!"

"Wait, there seems to be an entrance over there, why don't we face that entrance first, each of us use our special moves, bomb it, and give them a warning!?"

One of them suggested, and the others thought it made sense.

"Okay! Let's bomb it first!"

Bo Ding waved his hand back and took the lead, turning his hand to condense the fairy energy and slapped it out with one palm.

"Roar!" A golden dragon flew along the entrance of the Klein bottle.

Bo Ding's eyes were full of pride.

With his Daluo Jinxian cultivation, the special move he condensed should at least raze a city in Qianyuan Fairyland to the ground!
