Cheng Sikong and Shu Yungui waited until Xi Zimo's body was packed into a body bag and carried away before leaving the second basement floor.

As you continue down the steep slope, you can clearly feel the chill in the ground through the hazmat suit.

"It's amazing to say, it's so cold underground, but the further you go to the center of the earth, the warmer it gets."

Shu Yungui rubbed his cold arm through the protective suit: "Who would have thought that such a terrifying behemoth would live in the depths of the earth."

Cheng Sikong held a flashlight with a strong light, and said without replying: "Maybe for the Cree Zerg, we humans are terrible monsters, not only invading their homes, but also experimenting with them."

Shu Yungui followed Cheng Sikong and walked one foot deeper, one foot shallow, and asked, "You say, where will they go after they leave the Hope Star Field?" In the more than 1,400 years that humans have occupied the Hope Field, where have they lived?"

Cheng Sikong smiled: "You should ask Lin Ai this question, I can't answer you."

The elevator entrance on the third floor of the chatting room appeared in front of them, and fellow agents blew up the car with miniature explosives, opening the only entrance to the area.

The muddy water flowed down the dumped elevator, and as soon as the bright flashlight in Cheng Sikong's hand shone in, he saw a familiar figure in front of him.

"Killer Bear?"

Shu Yungui walked forward, the killer bear was locked in the victimized capsule, because the upper building collapsed and caused the earthquake on the lower floor, at this time the victimized cabin had tilted, but fortunately, it was not damaged, and the killer bear that was forced to sleep showed no signs of awakening for the time being.

"This is the first mutant mutant that has befallen me,...... I remember that it was, it seems that its vicious transformation process has deepened again, no wonder it will be forced to sleep, I guess the monastery is a little unable to control it."

The agents followed up and injected the potion into the cattle, which needed to be soaked for a while to ensure that the malignants would not wake up during the opening of the pod and during transportation.

The entire three underground floors are densely packed with impacted cabins, and there are detailed malignant detention times next to each impeded cabin, Shu Yungui took a cursory look at it, and found that the earliest malignant detention time can be traced back to 1390.

He should have entered the monastery at the same time as Lin Ai, and the malignant transformation process was very fast, so he would be imprisoned in the cathedral in less than a year.

Lin Ai, who is as big as it, is already a mother, but this evil mutant can still be seen in the size of a child, and his life is forever frozen at that time.

Suddenly remembering that he was about to become one of them, Shu Yungui felt afraid, so he took two steps back, and let the detectives deal with these long-sealed mutants.

Compared with Shu Yungui's empathy, Cheng Sikong was obviously much calmer, perhaps he was used to seeing malignant mutants in the IAFA base, and he didn't have much reaction to the various terrifying humanoid creatures in the impacted cabin in front of him, he bypassed the many impacted cabins and walked towards the end of the laboratory.

The light was obscured by the layers of containment chambers, and by the time it reached the end of the laboratory, it was already very faint, and there was a row of shelves on which many file boxes were neatly stored.

It is difficult to see so many paper documents in an all-electronic information society like Hope Star Field, Cheng Sikong pulled out the most remote file box and came down and saw the big words "1185 Human Insect Gene Fusion Test Forced Termination Notice" written on the side of the dusty box.

The human-insect gene fusion experiment began in the new ephemeris of 1185 and ended in 1288, so this document should have been signed around 1288.

Cheng Sikong opened the box, and a thick pile of documents detailed the results of all the insect gene fusion tests carried out in the monastery since 1185, Cheng Sikong took a hasty look and found that the number of people who voluntarily or involuntarily underwent genetic tests at that time was as high as tens of millions.

And every trial is a group of people, and many people are completely unaware of the fact that fusion trials are secretly carried out by medical means.

This is dozens of times more than the data reported to the Alliance, and it is no wonder that 90% of the population can carry the Cree recessive gene in just 100 years.

But judging from this document, the results of each group trial are:

Far from ideal, humans and the Cree colony seem to have an innate population isolation, and their genes cannot be fused by natural means, so all experiments between 1185 and 1288 have failed.

Behind each experiment was a huge amount of money from the Alliance, and the Coalition government, which had not seen results for a long time, finally chose to abolish the experiment, and officially issued a cease and desist letter in 1288.

Cheng Sikong flipped the document to the end, but he didn't see the specific signing date, only saw a name in the name of the signatory that surprised him.

"What are you doing?"

Shu Yungui's voice suddenly sounded behind him, originally Shu Yungui saw that Cheng Sikong had been standing here, bored and wanted to scare him, but he didn't expect Cheng Sikong, who had always been calm and composed, to be really frightened, suddenly closed the file box in his hand, and looked back at him with a panicked face.

"What's wrong?"

Shu Yungui rarely saw Cheng Sikong's appearance, his eyes fell on the file box in his hand, and he reached out to take it, laughing at him by the way: "What good things look so fascinating?"

Cheng Sikong seemed to be deliberately hiding from him, put the file box behind him, and coughed lightly: "No, there is nothing to see, let's go and see the situation of the transfer of the malignant mutant."

He raised his hand and pushed Shu Yungui's shoulder, but Shu Yungui refused to move, wondering, "What is so mysterious? Still won't let me see it?"

He leaned behind Cheng Sikong and grabbed the corner of the file box, neither of them refused to let go, so they were deadlocked.

"The more you don't let me see it, the more it means that something in it has something to do with me."

Shu Yungui secretly exerted his strength, the smile on his face was also put away, and he frowned slightly: "I'm not a child who needs to be protected, and I didn't participate in these things on the first day, I am the only third-order mutant in the human race, if there is anything in this world that even you find difficult, then the only person who can solve it for you is me."

Cheng Sikong's hand loosened slightly, Shu Yungui snatched the file box with his strength, and looked at the words on the box intently.

"1185 Human Worm Gene Fusion Test Mandatory Termination Notification Letter?"

He looked back and forth around the box and asked, "What's there about this that I can't see?"

Cheng Sikong seemed to regret giving him the file box, and immediately reached out to grab it: "There's nothing to see, it's your own suspicion."

"I haven't finished reading it yet! Why are you in a hurry?!"

Shu Yungui hid with the box, and the box was scattered during the dispute between the two, and the documents inside were scattered all over the ground.

"Tsk...... Don't rob it!"

Shu Yungui squatted down, picking up scattered documents in the muddy water, and while picking them up, he scolded Cheng Sikong.

"Although I don't know as much about these things as you, but I was personally selected by Teacher Ang to join IAFA, and immediately IAFA will take over the work of the monastery, and you will be even busier, some things can actually be left to me to do, and there are Xinyue and Jiang Ruzhou to help......

When his fingers touched a familiar name, Shu Yungui was stunned and almost bit his tongue.

He picked up the paper from the muddy water, turned to the bright light and looked at it carefully, and was shocked to find that the column of the signatory of the document was written in three large characters-

Shu Tongze.

"This ...... How is this possible......

Shu Yungui immediately stood up, holding the document and said to Cheng Sikong, "My grandfather is only 76 years old this year, how can his name appear on a document from 123 years ago?!"

Realizing that something was wrong, Shu Yungui immediately said again, "It's not right...... Wrong...... Regardless of when this document was written, the point is how could my grandfather have anything to do with the alliance and the gene fusion trial?!"

A huge sense of surprise welled up in his heart, which made Shu Yun panic.

"You calm down first, this matter is not simple, I wanted to investigate it clearly and then tell you."

Shu Yungui propped himself on the bulkhead of the impacted cabin with one hand, took a few deep breaths, tried to calm his tone, and said, "For as long as I can remember, grandpa has always been at home, he is just a stubborn old man, and he even suffers from old age

Dementia, I don't even know it anymore, how can it be related to these things?"

"But your grandfather's name will not appear on the document for no reason, you don't mess up because you are a relative, the most important thing now is to forget the identity of Shu Tongze and you, let's carefully sort out this matter."

Shu Yungui closed his eyes and nodded vigorously, and when he opened his eyes again, he had calmed down, and said in a deep voice: "This document is written about the notification letter of compulsory termination of the 1185 human insect gene fusion test, we preconceived that it was signed in 1288, but is there a possibility that this document was signed after 1288?"

Cheng Sikong said thoughtfully: "According to the normal understanding, it is believed that the experiment was terminated in 1288, but the monastery that should have been dissolved is still secretly conducting the experiment, and they actually did not terminate the experiment according to the requirements of the alliance."

Shu Yungui said: "That's right, in 1388, a batch of gene fusion drugs carrying the queen's worm nucleus were sent to the neonatal departments of major hospitals in the Hope Star Field, and were injected into the newborn's body, until 1390, when the first case of human malignant Lin Ai appeared, and the monastery had a legitimate reason to resurface."

"If the Confederacy did not finance the monastery in the 100 years from 1288 to 1388, who was behind the cost of such a massive experiment? And who hid them so well that no one found out for a hundred years?"

Cheng Sikong bent his finger on his chin, and thought quickly in his mind: "The mastermind behind the scenes must have power and money, and at the same time, the gene fusion experiment must be very profitable for him, and this kind of plot will even exceed the scope of our normal people's understanding."

Shu Yungui clenched the piece of paper tightly: "My grandfather was born in 1335, if this document was really signed by him himself, it can only be signed before I was born."

"Based on the information we have so far, the key clue is still with your grandfather, and we must know what role your grandfather played in this matter."

Cheng Sikong said firmly: "Let's go back now, and be sure to find out your grandfather's detailed life history!"
