Xiao Yu felt like he was almost suffocating. Regarding the identity of 'Shadow', in the previous conversation with Liu Wei, he had a hazy premonition, but when this sentence really came out of Liu Wei's mouth and put it in front of him, he still couldn't believe that a father would send his biological children who were not yet minors to do that kind of experiment.

For a while, the scenes of getting along with 'Shadow' in the past were repeated in Xiao Yu's mind, the most mysterious girl in this underground base, it turned out that she still had this identity, no wonder, there were so many people in the base, only she knew the secret passage to the mysterious valley outside and the password to open the outermost door, presumably, this was secretly revealed to her by Liu Wei.

Could it be that this Liu Wei is the kind of scientific madman played in the movie, who is desperate for academic research and can even give up his own daughter? Xiao Yu's gaze swept to Liu Wei again, but found that in addition to pain, his eyes at this time also hid calmness and wisdom, where did he seem to have lost his mind? Xiao Yu concluded that the reason why Liu Wei did this must have something unspeakable.

Sure enough, Liu Wei smiled bitterly and said to Xiao Yu, "Xiao Yu, maybe you will think that I am the most ruthless and incompetent father in the world, pushing my daughter into the fire pit, but I have no way to do it!" ”

Liu Wei's voice suddenly became deeper, "Xiaoying's physique was not good after birth, and he was diagnosed with a rare blood disease when he was two years old-' Jin's hemolysis', I took advantage of the relationship to invite several of the most famous blood disease experts in China to consult her, but these experts all came to the same conclusion, they told me that the probability of the onset of this disease is 1 in 10 million, it can be called a terminal disease, there is no cure at all, people with this disease, the longest life is not more than 20 years old, with my daughter's constitution, I am thankful that I can live to the age of fifteen. ”

Speaking of this, Liu Wei's face suddenly distorted, "But I'm not reconciled!" She is so well-behaved and lovely, her life has just begun, but she is about to wither, and fate is so unfair to her! So, I went crazy to study biomedicine, hoping to find a solution from my specialty, but it was so difficult, imagine that the well-known medical experts have spent decades trying to find an effective treatment for this condition, how can I do it in a short period of time? ”

"However, the military summoned biological and medical experts from all over the country to study alien blood gave me an excellent opportunity, and I used my previous research experience to successfully isolate the 'T' chromosome from alien blood and make it again. T1' blood sample, through experiments on monkeys, this blood sample has been proved to be extremely phagocytic and fusion, if my daughter can inject this blood sample, even if the fusion is only 1%, with the strong properties of this blood sample, my daughter can survive! ”

"Most of the people who participated in the 'blood group' experiment were elites from the army and some orphans with good physique found from the welfare home, I renamed Xiaoying 'Dugu Ying', and through the relationship, I got her the identity of an orphan in the welfare home, and took advantage of the convenience of being the person in charge of the technical aspect, and used her hands and feet when conducting the physical fitness test, which successfully made her a member of the 'blood group'."

"After injecting the T1 blood sample, Xiaoying's condition is surprisingly good, and her body is getting stronger day by day, and the person who has injected the 'T1' blood sample has two opportunities to fuse in his life, and in the test a year later, Xiaoying's first fusion reached an astonishing 40%, becoming the one with the highest fusion degree in the blood group, even higher than those elite fighters who have fused twice, and has unlimited potential. But...... But who would have thought that just when the ten-year experiment of the 'blood group' was about to be completed, everyone would have a genetic mutation, lose their minds, and become a killing machine! Knowing this, I might as well not let her participate in the experiment, and let her live happily for more than ten years! ”

Liu Wei's face showed an expression of extreme remorse, and he actually covered his face and cried.

Xiao Yu was stunned for a moment, his heart sank suddenly, seeing Liu Wei's painful appearance, could it be that he 'shadowed' her......

At the same time, a trace of doubt hit his heart again, and he couldn't help asking, "Uncle Liu, you just said that all the members of the 'blood group' have genetic mutations?" However, as far as I know, until the moment I left the underground base, Shadow did not go insane? In order to protect me, she even had a bloody battle with the people of the 'blood group'! ”

"What? Is there such a thing? Didn't Xiaoying have a genetic mutation? Liu Wei was shocked, his face immediately showed a look of surprise, and he took Xiao Yu's hand and said, "Oh, by the way, Xiao Yu, you once told me that it was Xiao Ying who saved you, that night, all the monitoring equipment in the underground base was destroyed, you are the only witness, tell me quickly, what happened that night?" ”

Xiao Yu sorted out his thoughts, and also told Liu Wei in detail what he saw and heard that night, Liu Wei's eyes became brighter and brighter, and after hearing it, he actually stood up from the sofa and walked back and forth in the study a few times, patted his head, and said to Xiao Yu, "I understand, Xiaoying is just a state of fusion, and the rest of the 'blood group' has completed the second fusion, which shows that the gene mutation should occur after the second fusion!" So that's it! Haha, I see! ”

Looking at the ecstatic look in Liu Wei's eyes, Xiao Yu couldn't help but sigh in his heart, is it true that people who engage in science are like this? My daughter's life and death are uncertain, what is there to be happy about? couldn't help but remind him, "Uncle Liu, can you be happy after talking about the whole thing?" ”

Liu Wei's emotions calmed down, sat down on the sofa again, and said to Xiao Yu with an apologetic face, "I'm sorry, Xiao Yu, I was so excited just now, do you know, if all this is true, Xiaoying will be saved!" And then it came like this......"

It turned out that a day after the bloody incident in the underground base, the people outside discovered the situation inside, and when they opened the gate of the base, they found that the entire base was full of blood, and there were stumps and broken arms everywhere, not only the members of the 'blood group' and the 'heart group' were all killed, but even those instructors, cooks, guards, and even ordinary soldiers who were responsible for cleaning the base were difficult to survive.

That scene was so tragic that until now Liu Wei thinks back to it, he can't help but retch a few times.

From the analysis of the situation at the scene, it should be that the people in the 'blood group' have a genetic mutation and become a blood-eating maniac who kills people when they see them, and the people of the 'heart group' are unwilling to be slaughtered, and they start the 'King Kong Warriors' counterattack, but helplessly, the 'blood group' has the largest number of people, and in the case of a sudden attack, the 'heart group' was caught off guard, and many members of the 'heart group' were killed before they entered the cockpit of their mecha.

However, the counterattack of the 'Heart Group' was also very sharp, and those members who activated the 'King Kong Warriors' were stimulated by the ruthless killing of their teammates, and they also went on a killing spree, fighting with the people of the 'Blood Group', and some even opened the most powerful 'King Kong Warriors' to kill the gods regardless of their lives.

After a thorough investigation of the underground base, the military personnel later counted that fifteen 'King Kong Warriors' had been permanently damaged and could no longer be used, and all the experimental facilities in the base had been unprecedentedly damaged, almost all of them had died, and only one person still had a faint breath of life.

That survivor is Shadow.
