"Ahh What a headache! Yes! Natasha covered her little head, half-knelt on the ground, and the alloy floor was shattered, propping up the floor with one hand and beating hard!

"Asahi, you get out of this area first, I'm going to start sedating." After the system steward finished speaking, Zhang Xu nodded.

……

"Asahi, the only thing I'm worried about now is my daughter, she has unprecedented pain, when she needs me the most, I am like a corpse, let these researchers dissect the experiment, but there is nothing to do!" Natasha had fallen asleep, like a fairy-tale princess, her cheeks sprinkled with hoarfrost.

"I feel very sorry for you and your daughter's situation, don't worry, I will take her like my own sister, whoever dares to bully her, I will definitely let that person be cut by a thousand cuts!" Zhang Xu looked at Natasha in the picture, his eyes were like fire, he smiled coldly, and said word by word from the heart.

"Asahi, I can trust you!"

"I was worried about you just now, but I didn't expect you to be able to catch my daughter's attack, what the hell is going on?"

"This is gene unlocking, gene unlocking is the future evolutionary development trend of human beings, and the development of genes can unlock the genetic lock of human beings faster and promote the transcendence of ordinary people."

"I'm now divided into level 10, in fact, theoretically my strength can reach about 40 tons, but my physical strength can only maintain about a dozen tons now." Zhang Xu smiled bitterly, if he didn't want to try to enhance himself, it might be difficult to match his strength, and he would never be able to use his full strength, although gene unlocking could enhance the strength of his body, but that was only a part.

"Asahi, can you trust me?"

"......" Zhang Xu In the last days, except for the evolutionary who he helped to become, he would have doubts.

"This is the most stable potion in the laboratory, and it is also the medicine that is injected into the daughter!" After saying that, the system steward showed a silver reagent on the screen, along with its detailed data and analysis.

"What does it do?" Zhang Xu raised his eyebrows and asked, he didn't want to be deceived by the system he just knew, and finally be sold and help it lose money.

"Not only does it enhance the metabolism of human cells, but it also absorbs titanium to enhance the density and hardness of your cells!"

"That's it, this is the titanium max-310 reagent, it uses pure liquid titanium plus the biological virus developed in this laboratory - Farla, this Farla virus can perfectly absorb titanium particles, and finally after being injected into the human body, Farla will fuse human cells, so as to genetically absorb the characteristics of titanium, and the next generation of new cells will have the property of absorbing titanium, as long as the experimental subject is infused with 50% of the human body, it is no problem, my daughter is infused with 78% titanium, and more than 80% It will be poisoned by metal and cause the internal disintegration of the cells, and you will not live for 3 days! ”

"Is this Farra virus okay?"

"Well, absolutely no problem, you must know that titanium, it is the only metal that has no effect on human vegetative nerves and taste, and this virus does not cause any harm to the human body, if it exceeds 50% to 80% of the safe tolerance value, it will be the same as my daughter, and when it is emotional, it will go berserk, and all moving items will be destroyed during this period!"

"Are there no other side effects other than this?" Zhang Xu repeatedly questioned whether this was safe.

"It's gone!" The system steward said categorically.

"Hmm~ This is video material, you can observe." The system housekeeper was afraid that Zhang Xu would not be at ease, so he gave him a video material.

Seriously, if this potion really has no side effects, then Zhang Xu will be like a tiger, which is equivalent to replacing his skin with titanium, and the power and power that can be exerted are definitely very different!

It's the rhythm of the heartbeat!

……

"Why is this reagent model different?"

"It is said to be an upgraded version of the original, with more significant effects and less harm!" Zhang Xu's suspenseful heart slowly fell, and his eyes were still a little skeptical when he looked at the system steward.

"The 419th experiment, titanium max-286 was injected, and the experiment was successful!" There is no one else on the screen, it is Marcia Natasha, what skipped a week, Natasha was put into a secret room, in front of her was a cubic meter of titanium metal block, the silver-white whole body was slowly decreasing, as if blown away by sand, similar to weathering, and the white metal particles all glanced at Natasha who was curled up in the corner.

Due to the deep excitement of the scientist, the scientist forgot to isolate the titanium metal, causing Natasha to overabsorb the metal, and the heartbeat of the extremely fast bounce was 573 per minute, as if it was about to jump out of her chest, only 2% away from the edge of death, you must know that the heartbeat limit of a normal person is more than 200 per minute, and then it enters a state of rage, which is what the researchers call - Valkyrie battle mode!

"A heart rate of 573 per minute, so high? She's not a genetically unlocked evolutionary! Zhang Xu's eyes were about to pop out, and he didn't believe this set of data at all.

"In fact, we don't know the limit of human beings, it is said that the strength of human limits is hundreds of catties, or people who exercise regularly, but there are some mothers who see their children being crushed by trucks and lifting them with their bare hands, this is really happening, and the science explains it as - the emergency response of the human body!"

"Emergency response?" It's not the first time Zhang Xu has heard this word, but he broke up with Xuan Zhinuo at that time, so in biology class, it was basically the left ear in and the right ear out, and he needed to learn this emergency response.

"The emergency response refers to the adaptive response of the sympathetic-adrenal medullary system when the body is suddenly exposed to a strong noxious stimulus!"

"When the body is in a special emergency, such as fear, severe anxiety, severe pain, blood loss, dehydration, extreme cold and heat, or hypoxic asphyxia, these stimuli immediately mobilize the activity of the sympathetic-adrenal medullary system through the central nervous system."

"The catecholamines released, in turn, increase the excitability of the central nervous system, making the body more alert and more responsive; increased respiratory rate and increased minute ventilation; The heart rate is accelerated, the cardiac contraction is strengthened, the cardiac output is increased, the blood pressure is raised, and the blood circulation is accelerated; The splanchnic blood vessels constrict, the muscles have more blood flow, and the blood is redistributed, so that the vital organs should get more blood flow in time; The biological oxidation conditions are better, the metabolism of substances also changes accordingly, the liver glycogenolysis is strengthened, and the free fatty acids in the blood are increased, which help the body to obtain sufficient energy, promote muscle work, reduce fatigue information to the nerve center, and enable the muscles to work for a longer time; Catecholamine CA can also inhibit insulin secretion by acting on α receptors on insulin B cells to help increase blood sugar! ”

"Generally speaking, when a person is threatened or has enough desire to survive, the muscle groups of the human body will be exerted to exert 2 points of strength, and when it comes to the moment of life and death, the emergency response will make the muscle strength of ordinary people play to 8 points! That's almost 4 times or more than the original one! So some mothers can overturn the car for the sake of their children! The system steward said.

"Then why don't you exert the remaining two points of strength and keep it for the New Year?" Zhang Xu was rolled his eyes by the system steward.

"Did you kid go to high school? Didn't you talk about it in biology class? These two forces are used to replace alternately to prevent overexertion of muscles, if used, at the moment of emergency response, the human body will burst like a balloon, like ordinary people can only hold on to this effect for a few seconds, and like my daughter and you, I am not good at calculating! ”

"Hey, you kid has decided whether to tie or not."

"Well, I want this reagent!"

After speaking, Zhang Xu was led by the robot to a hidden room, a huge box popped up on the white table, white smoke was billowing inside, and the cold air was blowing, this reagent must be refrigerated to keep the virus active!

Zhang Xu opened the shirt on his arm and pushed the needle, the silver-white potion became as thick as a small snake along the blood vessels, and the agitated green tendons burst out, and the severe pain seemed to tear Zhang Xu's lungs and brain, just like that, Zhang Xu fell asleep.
