In the dark crypt laboratory, Le Chen was lying on the operating table, and for several days, he had been sliced and studied by the crypt hybrid researchers, as if the crypt scientists were developing a potion that could control the sanity of the Mengjia tribe, and the research of this potion had been carried out secretly for hundreds of years, and now, it was close to the completion stage, and Le Chen became a guinea pig in this final stage, especially, the crypt elders judged that Le Chen was a fraudulent Mengjia tribe, which was a strange commodity, because the cave tribe was not sure about the medicinal properties of this medicine, that is, whether it could control the deceptive high-level individuals of the Mengjia tribe。

Le Chen didn't resist, and in the past few days, he learned from the words of the cave elder and the leopard girl that Hu Hei was not on this crypt planet, but sent to the headquarters of a certain resistance army to interrogate the information of the Mengjia security army in this quadrant.

Le Chen can only consider himself unlucky, but the crypt people may have successfully developed a potion to control the sanity of the Mengjia clan, if it is really successful, then not to mention that there is an extra shortcut to use this potion to quell the rebellion in this star field, that is, it will be equivalent to cutting off one of the arms of the frost nobles in the future, so Le Chen also hopes that this potion can really play an effective role, so that if he gets it, he can further improve the kingdom's scientific research strength so that it can be put on the battlefield and can be mass-produced.

Of course, the taste of being injected with various drugs all day long on the operating table is not pleasant, and Le Chen lives like a year, but whether the medicine can be successful or not, he feels the most directly.

The principle of this potion is actually to directly cause the Mongols to brain death, but at the same time, new brain cells will quickly grow in the Mongol shell to control the shell, that is, kill the old individual to give birth to the new individual, and the new individual has a lower IQ, similar to an animal that acts completely on instinct, but will treat the caveman's breath as their mother and protect it and obey the caveman's orders.

If this potion is really successful, Le Chen will also be brain dead and jump out of this body, which will generate a new consciousness and become a slave of the cave people.

In the torment of being injected with the potion, Le Chen was pondering that this medicine should also be able to use the physiological characteristics of other races, so that the Mengjia tribe regarded them as the mother of the offspring of the breeding race and served them.

However, speaking of which, this biochemical drug may be more vicious in nature than the genetic virus developed by the Frost Guiren against the mother planet, it seems that this drug did not cause genocide, but in fact it is not much different from genocide, perhaps, it was put by the cave people who were slaughtered by the Menga people of tens of billions of people, so as not to arouse strong criticism from those moral fighters, after all, the Genocide of the cave people by the Mengjia people is an ironclad fact, but the empire has no power to interfere, and the Frost Guiren completely ignore it.

Lying on the operating table, Le Chen was thinking wildly, suddenly, the cave began to vibrate violently, as if it was a shock wave from the ground, boom, and the criss-crossing crypts through the cave people were shaking violently.

With a "bang", a rock smashed on Le Chen's body, but the entire crypt was extremely quiet, as if all the cave people had disappeared.

However, after living with them for a while, Le Chen understands that now they must be hiding all over the crypt and making their physiological state enter a state similar to animal hibernation to avoid the enemy's search.

However, today's events seem to be very unusual, and the violent tremors of the cave did not stop as before, but trembled more and more violently.

"Boom", the entire crypt laboratory suddenly collapsed, and countless boulders buried Le Chen.

Le Chen was about to make a move, but suddenly his body stiffened, but the brain stem in his Mengjia body was rapidly aging, and it was the effect of the cave man's medicine!

Le Chen smiled bitterly in his heart, this is really a coincidence, if he jumps out of this body now, he doesn't know if it will be exposed, because it is obvious that the hiding place of the cave people here has been discovered by the Mengjia people, and now there must be a Mengjia starship on the side.

After a little groaning, Le Chen's mind moved, and the brain stem in the original Mengjia human body quickly died, and then, the medicine continued to work, and the new brain cells and cerebral cortex quickly divided, and quickly connected with Ao Guo's original light brain, so that the light brain could not determine that the body had died, and had been taken over by the newly born consciousness, but this newly born consciousness was still Le Chen.

Outside, there was a woman's crying, and the sound was the leopard girl, and then, with a few bangs, Le Chen's body was light, and the boulder that was pressing him was already torn apart.

"Dad, I'm not leaving, I'm not leaving!" In the dust, Le Chen saw that the leopard girl was holding a person in her arms, it was the cave elder, but at this moment he was already angry, and his silver eyes were extremely gray, as if the infused mercury was slowly flowing, which was a sign that the cave hybrid was about to die.

"Obedient, the rise and fall of our clan is on you, didn't you see that the experiment was successful? The original solution of the potion is also on you, and then take this puppet test product away, quickly!" Although the cave elder was no longer able to move, his words were extremely clear, but he was a little angry, obviously feeling that his daughter was too unprioritized, and it was really not the material to do big things.

Le Chen could only be speechless at the moment, the operating table could sense the changes caused by the medicine in his body, obviously no matter how critical, there were always cave researchers staring at the experimental data, but the medicine took effect, yes, but this newly born individual was not a cave puppet, but the experimental data could not be read.

Le Chen got up slowly, just when he didn't know if he should sneak away, but when he saw the leopard girl gritting her teeth, she put her father down, and then a miniature spaceship appeared beside her, she grabbed Le Chen's wrist and jumped into the spaceship, this spaceship, which can only accommodate two people, flashed hot silver light at the stern, and suddenly drilled into the ground, the hard rock layer was like tofu in front of the spaceship, and the spaceship moved rapidly, and it seemed to have reached the core of the planet in an instant.

The spaceship floated quietly in the fiery red magma, Le Chen closed her mouth and did not speak, the leopard girl wiped her tears, her silver eyes flashed, but they became human eyes, obviously in the spaceship, she no longer used those silver eyes to perceive this crypt world, her human eyes were extremely deep and charming, faintly blue, but from time to time she looked at Le Chen with hatred, which made Le Chen very helpless, and said that if she was impulsive, I don't know if she would kill her puppet to vent her anger.

Fortunately, it seems that the leopard girl is quite knowledgeable, although she looks at Le Chen's eyes very badly, but she still didn't make a move to Le Chen after all.

That's it, I don't know how many days have passed, Le Chen suddenly said, "I want to eat!"

The cave people have a special physique, they can sleep for months underground, and the same is true for the cave people's hybrids, but Le Chen's Mengjia body can't resist the attack of hunger.

The leopard girl glared at Le Chen viciously, and Le Chen had no choice but to shut up.
