Li Zhensheng and Yanzi may find it strange about the effect of this potion liquid, but Lin Yu is no stranger to it.

When he, Tan Kai and the others were ambushed by Mo Luo's men on Changbai Mountain, he had seen the power of this medicinal liquid with his own eyes.

As long as a person has been injected with the drug, he can hardly feel pain, and he is extremely resistant to blows, and even if he is seriously injured, he can still launch suicide attacks in a short period of time.

Only by hitting these people in the brain and damaging their central nervous system can you kill them completely.

"Genetic Liquid?!"

Li Zhensheng hurriedly said, "Sir, what you are talking about is the kind of medicine that Bu Cheng mentioned on the phone last time, and the special intelligence department is overcoming the bottleneck?!"

Lin Yu nodded and sighed, "Actually, the effect of the previous potion liquid is already extremely shocking, if they wait for them to make a breakthrough, I am afraid that the effect will be even more amazing!"

No wonder these gray-clothed figures are so strong, it turns out that these people also used the genetic liquid of the Special Intelligence Department.

Saying that, he couldn't help but turn his head and glance at Yanzi, with some admiration in his heart, he didn't expect Yanzi to be able to cope with it so well when he met someone who had injected this medicine for the first time.

But he knew that this was just the beginning, and in the future, once this drug made a further breakthrough and was widely used by the people under Wan Xiu's subordinates, it would be even more difficult to deal with it at that time.

For those who practice occult arts, the biggest barrier is not the exercises and mental techniques, but physical fitness, among which speed and strength are the most important, which limits the upper limit of many occult masters.

Now, the emergence of genetic liquid medicine has greatly made up for this shortcoming.

In this way, the strength of the people under Wan Xiu's command will be qualitatively improved after mastering the many mystical secrets handed down from the Xuanyi Sect.

Moreover, Wan Xiu can also use this medicine to attract more occult masters to join his camp.

After all, there are many occult masters in this world who dream of money and power all their lives, but constantly break through themselves!

Thinking of this, the pressure on Lin Yu's heart couldn't help but be heavier, and he had to admit that after receiving the support of the Special Intelligence Department, Wan Xiu had changed from a feared big devil to a behemoth that was difficult to shake!

"You can't even kill them if you don't hit the cranial nerves...... This genetic liquid is too terrifying......"

Li Zhensheng swallowed his saliva, he had only heard Bu Cheng and others tell before, so that he did not fully understand the power of the genetic liquid, but now he saw the bloody corpse in front of him, and he really felt the horror of this medicinal liquid for a while.

"And now that they have the help of the 'Father of Genes' Sincott, the speed of the improvement and breakthrough of the liquid medicine may be faster!"

Lin Yu said with a worried expression.

"Sir, then we have to come up with a way to deal with it as soon as possible, we can't sit still!"

Li Zhensheng said urgently, "Or we will also develop a similar drug to fight them!"

He believed that with Lin Yu's medical skills, he could develop a more powerful medicine.

"We can't develop it!"

Lin Yu smiled bitterly and shook his head.

"Why?"

Li Zhensheng's face was dazed, and he said suspiciously, "Compared with their World Medical Association, our World Association of Traditional Chinese Medicine is not bad at all, it also requires money and money, people and people, official support and official support, and there is no lack of anything!"

"Not only do we lack nothing, but we have one more thing, so we can't develop it!"

Lin Yu smiled bitterly.

"Oh, there's one more thing, you mean?!"

Li Zhensheng and Yanzi were both stunned when they heard his words, and they were puzzled, why did they have one more thing, but they couldn't develop it?

"Humanity!"

Lin Yu said categorically, looking up at the dark night, his expression was extremely cold.

Human nature?!

Li Zhensheng and Yanzi looked at each other for a while, even more puzzled.

"The development of this drug mainly depends not on technology and money, but on white bones, white bones!"

Lin Yu's expression was sad and indignant for a while, and he said coldly, "The effect of this medicinal liquid can reach this point, it is piled up with countless corpses!"

Many people think that the birth of powerful genetic drugs only needs powerful technology and a steady stream of financial support, but in fact, what they need most is actually countless live subjects for experiments.

The more successful the genetic liquid in the Special Intelligence Division, the more people died tragically under their experiments!

Only by constantly experimenting with the human body and constantly improving the defects in the liquid medicine can the efficacy of the drug be continuously improved.

And the more you get to the end, the more difficult it is to perfect and break through the drug, the more experimental subjects are needed, and the more people die tragically!

"Doesn't that mean that we don't know how many children have died at their hands......

Li Zhensheng suddenly wanted to start accepting what he had said at this time, and his heart trembled, but he didn't expect the reality to be more terrifying than he imagined.

"To make a breakthrough in this efficacy......"

Lin Yu swept the two corpses on the ground and said in a deep voice, "The children used are at least millions!"
