Qi Qi hugged Yu Xi twice and kissed him twice, but stopped after being pushed away by Yu Xi.

"You are so sweet."

"You have said this several times."

"Because it's the truth."

Qi Qi licked her lips. In fact, she had never eaten sweets, and she didn't know what sweetness was, but the sense of taste in the database told her.

Her heart was beating, Qi Qi felt puzzledly, her body data was all normal, why would her heart be beating at an abnormal frequency?

"What's wrong?"

"It's jumping fast here, why?"

Qi Qi pointed to the position of his heart.

"because I."

Yu Xi held Qiqi's hand and interlocked her fingers.

Feeling an electric current rushing in from the fingertips, flowing through the limbs, and then hitting the heart directly.

"Jump faster."

"Um."

Qi Qi will always remember this scene. The dusk is dim. At the corner of the street, Yu Xi is smiling and her eyes are bright, as beautiful as stars.

Why is my heart beating so fast?

Because of me.

"I am very happy."

Yu Xi stood on tiptoe and touched Qiqi's head. She was about the same height as Qiqi.

"Because of me?"

"Um."

I am very happy, all your joys, sorrows, sorrows and joys surround me.

"Then I am happy too."

Qi Qi showed a smile on his headless conversation, feeling that everything is beautiful, including this dilapidated city.

Yu Xi and Qi Qi headed in the direction of R City. They got a car with its door open, and the owner had turned into a zombie.

The car was a bit dirty. It was an ordinary sedan. Qi Qi was in the driver's seat and Yu Xi was in the passenger seat.

r city, the mountain behind the school.

When they returned to the place where they first met, Qi Qi nodded when she saw the familiar environment, and then she knew the way.

Yu Xi followed Qi Qi to the back mountain. After walking for a long time, he stopped at one place.

Yu Xi never knew that there was such a big secret hidden in the back of the school.

That is already the other side of the mountain, no one knows that such a secret place is hidden in the continuous mountains.

Qi Qi opened the code lock and walked into the research institute.

Yu Xi always followed Qi Qi. The structure of the institute was not complicated. Once you entered, there was a long corridor with rooms on both sides, but it was indeed airtight and you could not see anything.

"The low-level experimental products are generally on the negative level, here is the average."

At the end of the corridor, there is a large transparent laboratory in which various equipment is placed, but many of them are destroyed.

The institute is surprisingly quiet, and it feels empty.

At the other end of the corridor is the elevator, and the button on it is still on, indicating that it is still running.

Qi Qi pressed the up button and sat down with Yu Xi.

Qi Qi didn't remember how she got to city b from here. After solving the doctor, she always wanted to come back and take a look, and then tell a guy the good news.

The elevator reached the fourth floor and stopped.

The same purpose is the empty corridor, the wall material is very special, Yu Xi can't say it.

The rooms on this floor are transparent, and you can see the inside from the outside at a glance.

What Yu Xi saw was something that looked like a frog and a human, and it looked very strange.

"This guy is noisy."

Qi Qi pointed to the experimental product, because it croaked every day, so she couldn't resist breaking the wall and hit it several times, so that the wall became stronger and stronger, and the surveillance on her became more and more tight.

"It seems to be dead."

Yu Xi looked at the motionless frogman.

"may be."

Qi Qi didn't care about this and walked to the end of the corridor.

"This is my room."

Qi Qi pointed to the empty room. The door of this room was destroyed and a big hole was broken.

"It stands to reason that I should have done this."

Qi Qi turned around and knocked on the transparent door of the opposite room.

Yu Xi saw the experimental product. The experimental product in that room was sitting in the room. There was a delicate face like Qi Qi, which was not as beautiful as a human being.

She is indeed not like a human being. There are some thin wings on her back, which are butterflies.

Die Nu heard the movement, her closed eyes opened, and she looked at Qi Qi standing at the door in surprise and pressed it to the door.

"K7409! Why are you back again?"

Butterfly girl is very strange, after all, who can escape from here, who wants to come back.

"K6848, I'm back to see you."

Qi Qi spread out her hands. Before she was researched out, K6848 was the most perfect gene combination in the research institute. Unlike her repairing power and destructive power, K6848's abilities tended to be confusing.

Butterfly Girl is very envious of Qi Qi. Qi Qi’s appearance is no different from that of human beings. Even if she is in the crowd, she will not cause panic, but she can’t do it anymore. The wings behind her can’t be retracted. It is her weapon and her fatal weakness. , Even if she escaped, she could only shrink up, not to mention that she couldn't escape.

"Who wants you to come back, go quickly."

Die Nu's face changed, her expression became a little anxious.

"What are you doing so nervously? I'll come back and tell you that the old guy was killed by me."

Qi Qi was quite proud. She and Butterfly Girl should be friends, if there is friendship between the experimental objects.

At the very beginning, the two of them fought against each other. Of course, the butterfly girl abused Qiqi into a dog, but as Qiqi grew up, the butterfly girl gradually lost her position. The first strongest in the institute also gave way to Qiqi, but Still the two people struggled often, and after they were both infused with wisdom, they turned into verbal violence.

"real?"

Butterfly Girl was a little excited. They used to get together except for fighting to discuss **** the old man. It was too annoying.

"real."

"K7409, you shouldn't be back, the current research institute has a new owner."

Butterfly Girl's expression was a little gloomy, her body couldn't help trembling, and those terrifying pictures appeared in her mind. That person was a devil, even crazier than the doctor.

"what?"

"She wanted to catch you, but you delivered it yourself."

Butterfly Girl gave Qi Qi a self-seeking expression and sat back on the bed.

Yu Xi only saw that Butterfly Girl's slender ankle had a thin chain attached to the foot of the bed.

Da da da……

The sound of footsteps was particularly obvious in the empty corridor. Yu Xi and Qi Qi turned their heads and saw people walking by.

It was a woman wearing a white coat, short hair, a pair of black-rimmed glasses, and a white mask.

"K7409? I didn't expect you to come back by yourself."

The woman's voice was a little low, with a little surprise.

This should be the new owner in the mouth of Butterfly Girl.

"Who are you?"

Qi Qi is sure that she has never seen this person before. The butterfly girl has shrunk on the bed and looks very scared. He did not see her when Qi Qi hit her before and when she was injected with a new experiment by the doctor. So scared, this can only show that the woman in front of me is terrible.

The woman took out something similar to a remote control in her pocket and gently pressed it, stepped back a few steps, leaned against the wall, and looked at Yu Xi and Qi Qi with a lot of enthusiasm in her eyes.

This experimental product is really fascinating, especially her ability to regenerate and repair has super kill ability, if she can have such power...this world...will definitely be in her pocket, The metabolism of the experimental product is abnormally slow. Research on her body data shows that it is likely to have a ratio of 1:100 to a normal person. One hundred days of a normal person is equivalent to her day. If she has such a body function... even if it is not a longevity I am not old, and it can exceed normal people a lot.

A glass door opened and something crawled out.

"E3204."

Qi Qi squinted at the weird-looking woman in front of her, and she felt that E3204's body had changed.

E3204 is a combination of a spider and a human. Yu Xi can tell at a glance that compared to Qi Qi and Die Nu, the spider woman has too spicy eyes.

The eyes on her face are huge in proportion, looking terrifying and disgusting. She has hands and legs, but she is crawling.

[Host, I want to mosaic her, it's disgusting, she looks even uglier than the zombies outside. 】

There was a weird creepy sound in the spider girl's throat, her body changed, her clothes were torn, and her normal body was torn and turned into a spider's appearance, just a human face.

[Ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhāy, eyes are more pungent. 】

Spider silk overwhelmed the sky and struck towards Yu Xi and Qi Qi, and the spider girl's body became huge and she climbed to the ceiling.

The spider ribbon is corrosive and looks very hard. It is on the floor, there are fissures on the floor, and the walls are clinging to these things in a mess.

The woman smiled. She modified the high-level experimental products on the fourth floor of the Institute, and their abilities were stronger than before. She also extracted their wisdom and entered high-level instructions in their database. She felt that what her father did was real. It's too stupid. How can we make these things that are machines have human intelligence? This is playing with fire.

Yu Xi and Qi Qi had a tacit understanding of luck and ice power. Yu Xi erected an ice shield to block the attack and froze the spider silk by the way. Qi Qi directly froze the spider girl, and the surrounding spider girl dodged very quickly. Frozen and smooth, the spider girl couldn't cling to the wall, and fell down embarrassedly.

"waste."

The woman was a little displeased. She didn't expect that after just such a period of time, the ability of K7409 has reached this point, and it is actually stronger than before. This ice system's ability...

The woman felt a misstep. Her transformation was based on the old body data of K7409. She did not expect the growth rate of K7409 to be so terrible, and the humans around her...

Yu Xi and Qi Qi joined forces to deal with the huge spider girl. The spider girl could not get close at all. She was imprisoned in the ice block, her body spurted out spider silks subconsciously, and Yu Xi and Qi Qi strengthened the hardness of the ice block. , The spider silk could not break out of the ice block, and was entangled in the ice block. Looking at it, it was like a huge cocoon frozen in the ice block.

The woman took a few steps back and pressed quickly on the remote.

Yu Xi is also concentrating on summoning at this moment, the zombies nearby, come over.
