"Or else?"

Hearing this, Lin Cheng was not the slightest surprised, "Before the end of the world came, they began to secretly study the Eater, and after the end of the world, even the research institute was attacked by the test subject, but they still did not give up the research and development of the test body, such perseverance, coupled with the super vigilance against you and those guards, who do you think would really think that they want to build a resistance army in the end times?" ”

"yes......"

Hearing this, Meng Yi also smiled bitterly and nodded, "Actually, everyone gradually became aware of the true intentions of the headquarters later, but ...... Seriously, it's the end of the world now, and there are monsters running rampant outside, in this case, as long as you have a full bite to eat, who do you think cares if what you are doing is right or wrong? ”

"Hmm...... Also. ”

Hearing Meng Yi's words, Lin Cheng quite understood, the outside world was rampant with monsters, and no one knew when and where a nibder would pop out, compared to this kind of precarious day when there was no hope at all, this underground research institute was like heaven, except for the daily study of those test subjects who had been injected with stabilizing potions and were not a big threat, there was no other threat to life.

Seeing that Lin Cheng listened carefully, Meng Yi continued: "With the help of the stabilizing elixir, our research institute has finally gotten rid of the threat of these test subjects, but on the other hand, we have not been able to successfully control the test subjects while removing the stabilizing elixir, which has resulted in the fact that although we have a large number of test subjects in our hands, they can only be like animals in the zoo, with an empty pair of skins, but completely without their own instincts......"

"Looking at it this way, are you still failing?"

Thinking of the test subject he had seen in the internal laboratory before, which had almost completely lost its combat effectiveness after being injected with a stabilizing agent, Lin Cheng nodded, and then asked.

"It's basically a failure......"

Hearing this, Meng Yi sighed softly, "And the headquarters has always been very dissatisfied with the progress of these new test subjects numbered 'Plan B', and has sent people to urge us to speed up the research and development progress more than once, but what they don't understand is that as long as we can't solve the secret of the 'X' element for a day, we will never be able to truly control these test subjects!" ”

"It's a ghost if you can control it......"

Hearing this, Lin Cheng couldn't help muttering in his heart, the 'X' element, that is, the 'apocalyptic pathogen' is the core that supports the survival of zombies and eaters, this kind of thing itself is extremely evil and uncontrollable, any creature except these monsters themselves, as long as they get a little 'apocalyptic pathogen', they will die immediately, but these researchers are vainly trying to use their three-legged cat's biological theory to try to control them, it is simply a trick to die!

There is no need to ask at all, Lin Cheng can easily guess that there are more than one or two researchers in this underground research institute who died at the hands of the 'doomsday pathogens', and they themselves should have been aware of it, although they don't know how these people successfully extracted the 'doomsday pathogens' alive from the enhanced stock solution, but there is one thing that no one can change, that is, with the current level of science and technology mastered by human beings, no one can really unlock the secret of the 'doomsday pathogens'!

Sensing the disdain on Lin Cheng's face, Meng Yiliu raised his eyebrows and asked a little suspiciously, "Why...... Why do I always feel like you know so much more than I thought I would? ”

"I've been out there for half a year, shouldn't I know more than I know?"

Hearing this, Lin Cheng shook his head lightly, and casually found a reason to prevaricate.

Although he has basically sorted out the situation of this underground research institute, he is still not interested in revealing too many secrets to this Meng Yi, the purpose of his coming here is just to find Chen Jiajie and try to find out some truth about the coming of the end of the world from his mouth, now it seems that although this purpose has not been achieved, it has also made him get a lot of unexpected gains!

"So after the situation has been deadlocked for a while, your headquarters finally can't hold back and decided to restart that 'Plan A'?"

In order to prevent Meng Yi from asking himself other questions, Lin Cheng diverted the topic and asked her about 'Plan A' again.

Hearing this, although Meng Yi's doubts in her heart became more and more intense, she was not a fool after all, and she knew that asking again was likely to cause unnecessary trouble for herself, so she replied: "Yes, the purpose of the headquarters to train us is to help them develop a post-apocalyptic iron horse, but we can't conduct further research here for various reasons, so the decision of the headquarters to restart 'Plan A' is actually my expected decision, but I didn't expect them to bring up this matter so soon......"

"I admit that although 'Plan A' has such and such flaws, if it is only in terms of combat effectiveness, it has indeed met or even exceeded the requirements of the headquarters, and the headquarters will still make such requests knowing that the test subjects of 'Plan A' are difficult to control, I guess they have probably learned from the spies planted in our institute that three days ago, my team and I have developed a new agent that can effectively suppress the rage of the test subjects!"

"Wait a minute!"

Hearing Meng Yi's sudden revelation, Lin Cheng frowned, and hurriedly waved his hand to interrupt her, "What did you say?!" You've even developed a potion that can control test subjects?! ”

"It's not control, it's suppression!"

Seeing that Lin Cheng seemed to have misunderstood what he meant, Meng Yi shook his head and said, "Control means that they will do whatever they want these test subjects to do, while suppression is not, it just makes them no longer easily hurt people, and their combat effectiveness will not be greatly weakened......

"This ......"

After listening to Meng Yi's explanation, Lin Cheng's mind turned a few times before he finally reacted, "Listen to what you mean, isn't the test subject injected with the inhibitor still useless?" Have you ever seen the 'Iron Rider of the Last Days' that doesn't hurt people? ”

"No way, this is already the limit of what I can do......"

Hearing this, Meng Yi couldn't help but smile bitterly, "The suppression potion was only improved by me on the basis of stabilizing the potion, and it was originally intended to be taken out to make do with the exchange when the headquarters put pressure on us again, but I didn't expect that the headquarters knew everything about the movements of this research institute, and what I didn't expect was that after they learned that we had developed the suppression potion, they directly asked us to restart it." Plan A', which made all my previous plans fall through, and if I hadn't met you, I'd probably have started upstairs with the guards to look for 'A' by now......"
