After a complex review and sterilization, Du Bixing was able to enter.

The Human Genomics Research Institute is neat and clean, and there are all kinds of laboratories and equipment rooms that look very powerful.

"Hello, please follow me!" a guide robot came to lead the way.

Du Bixing walked and looked around. It's a pity that this place is heavily guarded, and it's impossible to see anything unbelievable.

"It's here. The guided robot took him to his destination: the human modification room.

The special metal door of the renovation room was closed, and not even a trace of light could be seen inside. A virtual screen outside the door shows that one of them is one of them, guiding the robot to enter a request to open the door, and soon, the request is granted.

The metal door opened automatically, and Du Bi walked inside. Once inside, the first thing is an office-like place, and the remodeling room is still behind.

"Hello, I'm here for physical strengthening. Du Bixing shouted inside, but unfortunately no one responded.

Du Bixing looked curiously at the transformation room, could it be there? He was thinking like this, when a voice suddenly came from above his head, saying, "Where is it!"

Du Bixing was startled, just now he didn't notice that there was anyone in this office at all, and he didn't even feel the breath of the creature!

When he looked up, he saw a sexy woman lying on the ceiling! Yes, she was sleeping on the ceiling in defiance of gravity!

The woman was leaning lazily against the ceiling as if she were basking in the sun on the beach, her eyes slightly closed. Two slender thighs together, beautiful posture!

What attracted Du Bixing's sight the most was the thing in front of him that his pair of hands could not grasp, because of the perspective, Du Bixing could clearly see the scale.

"There is absolutely no violation of gravity!" Du Bixing thought to himself, otherwise how could he be so proud of being pulled by gravity?

Originally, Du Bixing was surprised that someone would lie on the ceiling. But after seeing her face clearly, he took it for granted again.

This woman is the "demon girl" he met at the freshman party before, also known as the mutant of Black Widow, Qi Caiyi!

She has demon spider genes in her body, and there is extremely tough and sticky spider silk in her body, and walking on the wall is really as simple as breathing for her.

"Junior brother, where are your eyes?" Qi Caiyi opened his eyes and shouted.

Du Bixing hurriedly retracted his gaze and said, "Senior sister, this position ...... The location is inconvenient to speak. ”

Qi Caiyi snorted coldly, and then came down from the ceiling. She was as light as a swallow, and she slowly fell, and Du Bixing noticed that there was an almost imperceptible spider silk hanging from her, and when her feet hit the ground, the spider silk did not know where it went.

Mutants are really amazing! Du Bixing was secretly surprised in his heart, no wonder Qi Caiyi was feared, just with this spider silk method, her combat effectiveness can be imagined.

Qi Caiyi didn't say a word after he landed, but looked Du Bixing up and down. Not only that, but she also approached and ran her onion fingers across Du Bixing's skin. The subtle touch made Du Bixing's body tremble.

"Tsk, you're in good shape. This muscle, hard and strong, my sister likes this. Qi Caiyi said in a seductive tone, and Du Bixing could even feel the heat in her mouth.

"Uh, senior sister, I'm here for body strengthening. Du Bixing emphasized, he really didn't know what Qi Caiyi wanted to do?

And he still remembered that although Qi Caiyi was beautiful in appearance, there was a poison in his body that could poison the Great Martial Sect!

"I know. Qi Caiyi said, "Isn't this another physical examination for you?"

"Huh?" Du Bixing was a little stunned and asked, "Could it be that you strengthened my body?"

"What, you don't want to?" Qi Caiyi raised her eyebrows, as if Du Bixing would immediately kick Du Bixing out as long as she said she didn't want to.

Du Bixing hurriedly said: "Of course I am willing, I have worked hard." ”

"Count yourself lucky!" Qi Caiyi snorted, "Today the mentor is resting, so I'm here to give you a physical strengthening." ”

Du Bixing is still a little nervous, can this kind of difficult thing be done by relying on Qi Caiyi alone?

Qi Caiyi saw his nervousness, smiled slightly, and said, "Don't worry, in the entire research institute, my operation is absolutely top-notch." ”

Du Bixing was about to breathe a sigh of relief, but she said again: "But others don't think so, so I'll take you to practice first." ”

"Huh?" Du Bixing suddenly smiled bitterly, "Senior sister, don't scare me!"

"Hehe, it's just to scare you!" Qi Caiyi's face changed instantly, "Actually, the person who wanted to strengthen your body was driven away by me, and I didn't understand anything." ”

Du Bixing really didn't know whether what she said was true or not, so he had to beg for mercy: "Senior sister, I haven't offended you." I just want to do a physical enhancement in peace. ”

"It's a little timid. Qi Caiyi said with disdain, and then said: "Don't worry, I would have done this kind of experiment a few years earlier." ”

"Come here!" Qi Caiyi took Du Bixing to a place, which turned out to be the bathroom behind the office.

"Undress!" Qi Caiyi ordered.

"Huh?" Du Bixing was a little embarrassed.

"Take off your clothes, then take a shower, and disinfect your whole body to strengthen your body, understand?" Qi Caiyi said.

"I understand all these truths, but senior sister, can you go out first, do you want to take a bath with me?" Du Bixing said helplessly.

"yes. Qi Caiyi's tone suddenly became ambiguous, "Do you want it?"

"Don't!" Du Bixing said very resolutely, although he had a little expectation in his heart, reason told him that this demon girl was definitely teasing him.

"Hey, you just missed a chance to bathe with me. Qi Caiyi sighed, "Wash well, wash it and disinfect it with radiation, and then change into an isolation gown." ”

It wasn't until Qi Caiyi went out that Du Bixing breathed a sigh of relief in his heart, this woman is too capable of making trouble!

He was taking a bath in the bathroom, but he didn't know that outside, Qi Caiyi was watching through the surveillance. Not a voyeur, though, but a look at the various body data provided by the scans.

Seeing Du Bixing's body data, Qi Caiyi's eyebrows frowned slightly, and he said to himself: "This guy, the genes are a bit strong! The complete human genes are actually comparable to some demon clans! And the direction of genetic evolution seems to be different from that of ordinary martial arts sects." ”

"There is no genetic record like him in the database, and it is estimated that it is a mutative evolution. The second place in the assessment of the True Martial Academy, and it can also kill the Martial Sect-level beasts......" Qi Caiyi fell into deep thought.

After a long time, a bright color flashed in Qi Caiyi's eyes: "This guy is interesting! ”
