In the laboratory of Chen Yu, an affiliated hospital of the University of Tokyo Medical School, he was holding a test tube containing bright red liquid in his hand, preparing to use a dropper to extract the bright red liquid from it.

"Chen Yujun, is it really okay to do this?" Hokami Kazuno looked at the bright red test tube in Chen Yu's hand, and his face showed obvious concern and hesitation.

It was a dragon blood potion prepared by Chen Yu with a drop of her blood. Its base was a healing potion recorded in the "Common Necromantic Spells of the Multiverse". However, it was not for the dead, but a healing potion that was rare for necromancers, but in a sense it was normal for the living. After adding the blood of Bomi in the city with dragon blood, this potion had fundamental changes in its effect.

As for the specific effect... Chen Yu's lab destroyed a large number of mice that had become very violent after the dragon transformation last night. Chen Yu just drew a drop of this dragon blood healing potion to the mouth of each mouse used for the experiment.

Under the action of this drug, the body shape of the mouse undergoes fundamental changes. Not only does the hair on the surface of the body fall off and scales grow, but there are even huge bone spurs that grow out of the bones under the skin, piercing the skin. These mice, which are five times larger than those of the kitten, look quite hideous and terrifying.

Not only that, these guinea pigs also showed extremely aggressiveness and irresistible mania. Since they mutated, they were trying to attack everything around them frantically. Their crazy desire to attack forced Chen Yu to take advantage of her blood river ability and completely destroy these guinea pigs to completely eliminate the possibility of this creature reproduction and destroying his undead space.

The endless attack desire of these dragon-turned crazy rats is combined with the rat's amazing reproductive ability and gnawing ability. If you leave it alone, these guys will definitely be able to eat all the things they can bite in the undead space before they all starve to death.

However, after seeing the terrifying nature of the Dragon-turned Rat last night, seeing Chen Yu take out this dragon blood potion and still test the tube, it is no wonder that Bomei in the city is worried.

It's like when you just finished watching "Resident Evil" and someone broke the green test tube that was exactly the same as in the movie, you can't help but feel frightened.

"Don't worry, this is not the same potion as what you saw last night when I fed the mice. This is the potion I got after eliminating the negative effects. There will be no problem." Chen Yu explained to Homio, and at the same time made a guarantee.

In fact, he was also startled when he saw the violent attack desire of the Dragon-turned Rat last night, but he quickly realized that the reason why these teenage mice became violent and wanted to attack and destroy everything was actually affected by three aspects.

The first is the attack desire of the mice in their bloodline, and the second is that the genes of the dragon are too powerful for a mere teenage mouse. Even if it is just a tiny bit, it is enough to pollute the original genes of these teenage mice.

As for the third point, it is because it is the blood of Bomei in the city, and it is the source of the power of the Blood Knight.

Because Bomi in the city is a blood knight, and one of the abilities of the blood knight is to cultivate blood seeds through his own blood. The main component of the Immortal Army under the Blood Knights is their most loyal and powerful servant, the sharpest blade in the Blood Knights legion.

Blood Knights usually create blood seeds by killing creatures that are powerful enough to gain the favor of Blood Knights. Using the corpses of these powerful creatures plus the blood of Blood Knights, they can transform them into blood seeds who are absolutely loyal to Blood Knights and become one of their undead army.

Normally, the Blood Knight will not exert this ability on living creatures, because the Blood Knight's blood contains a rich blood power, which is enough to erode and destroy a creature's sanity, making it violent and bloodthirsty.

Of course, the more powerful the creature is, the more it can resist and withstand the power in the blood of the Blood Knight, but the guinea pig is obviously not listed.

After understanding this problem, Chen Yu naturally adopted another method to achieve his goals.

Chen Yu first eliminated the violent and bloodthirsty effects contained in the blood power of Bomei's blood in the city, and then diluted the dragon blood potion configured with the blood after eliminating the influence a hundred times, and injected it into the body of the pre-prepared experimental organism. After the experimental organism was manic and bloodthirsty, he extracted the blood carrying the dragon's power from these dragon creatures and reconfigured the healing potion.

"Is there really no problem? Even if Huizi's mother signed the agreement and agreed to let us try some new drugs on Huizi's father, it is not appropriate for you to do this?" Huoneuchi Hoshinomi looked at Chen Yu extracting a little of the medicine in the test tube with a dropper, and then added it to the therapeutic medicine produced by Jiuzhai Pharmaceutical that Jiuzhai Liangcen brought to him, and still felt uneasy.

Hearing Hokami Kanei say this, Chen Yu laughed indifferently: "Why do you think Bomi are inappropriate? Is it because there are regulations that cannot be applied to patients without permission, or are you afraid that this drug will make Keiko's father crazy and bloodthirsty? If it is the latter, you don't have to worry. This is the drug I reconfigured last night. I have done animal experiments and will not cause such serious consequences.

As for the former, it is just to eliminate some inhuman human experiments. What we are doing now is not human experiments, but just using some knowledge that others do not know to save people."

Chen Yu said that the dragon blood therapy agent extracted from the dropper had been added to the therapeutic agent produced by Jiuzhai Pharmaceutical and shaken it well.

The therapeutic agent produced by Jiuzhai Pharmaceutical is the Necrotic healing agent that Chen Yu gave them before. The original color of the agent should be a green opaque liquid, but with the addition of modern technology, Jiuzhai Pharmaceutical's products are light green transparent liquid.

And now... after Chen Yu added the dragon blood healing potion, the color of the potion has turned orange-red.

"Okay, Liang Cenjun, you take this to the ward and let the nurse give the patient an injection." Chen Yu looked at the medicine in his hand with satisfaction, nodded and handed it to Jiuzhai Liang Cen.

"Yes, professor." He took the medicine bottle containing the orange-red potion, nodded before leaving the laboratory.
