Seeing that Song Yi began to refine the new potion again, Professor Tan was helpless but also appreciative, and those who did research should have such a heart.

After that, they succeeded a few times, but unfortunately none of them had what Song Yi wanted, and there was one that was actually very close to what they needed, called the marrow washing potion, that's right, it can wash the muscles and cut the marrow, and it can eliminate impurities in the body.

"Well, is this okay?" After the marrow washing potion came out, they immediately found someone to do an experiment, after all, the marrow washing potion sounded similar to what they wanted.

"No," Assistant Wang shook his head: "After the patient drank the marrow washing potion, a lot of impurities in the body were discharged, even including radiation contamination, but it had little effect on the virus, at most it only slowed down the mutation of the virus." ”

"Radiation contamination can be ruled out, I don't know how much can be excluded." Professor Tan was a little surprised, before the end of the world, radiation pollution has always been their most troublesome problem, before the end of the society air and food have radiation, people are inevitably contaminated by radiation.

Once the pollution reaches a certain level, the human body will undergo irreversible distortion, and people can only reduce the pollution in the body by various methods, but cannot eradicate it.

"If the pollution is not serious, it can be eradicated, and if the pollution is serious, you need to drink it several times, but this agent is probably only more effective than the first three times." Assistant Wang said that as Professor Tan's assistant, he also helped to research agents that can repel radiation pollution, so Assistant Wang also attaches great importance to this.

"This potion can be recorded, but the most important thing at the moment is the medicine against the virus, since this potion can slow down the disease, it can be refined by others, we have to continue research." Song Yi's uncle specializes in research related to the expulsion of radiation pollution, and he knows a lot about this, so he said.

Professor Tan nodded, arranged for someone to refine the marrow washing potion, and turned his head to see that Song Yi was busy again.

"Would you like to take a break?" Professor Tan said with some worry that she had been busy for a day without a half a moment, so she just recovered her ability and rested halfway.

"It's okay, I can still hold on, anyway, I'm also a level 4 ability." Song Yi waved his hand.

"That's okay, if you can't hold on, don't force it, now there is a marrow washing potion that can be suppressed temporarily." Professor Tan looked at her and said.

"Okay." Song Yi nodded, began to select the material ratio, searched for the test tube containing the extracts of various materials, stopped when he skipped one of them, hesitated for a moment but picked it up.

"This is the highly toxic mutated plant extract." Professor Tan watched her pick it up and spoke.

"I know, but this is also a material that fits the magnetic field, so let's try it." Song Yi said, and then the ghost sent her, and she also picked up a bottle of cockroach virus.

The corners of Professor Tan's mouth twitched when he saw this scene, but he didn't say anything, it doesn't matter if he fails anyway, just start all over again.

The first few times were still failures, and the amount was not grasped well, but after more than a dozen times, Song Yi had mastered the required amount of various ingredients and began to try again.

This time it went well, the amount of each material was just right, and when the last material was put in, there was a light in the crucible, Professor Tan knew that this must be a success, and he saw Song Yi pour the cockroach virus into it.

"Ah, this ......" Professor Tan couldn't stop it, watching the originally clear and slightly blue light turn into a dull ink blue, a little lost.

"Assistant Wang, please appraise it." Song Yi turned his head and said to the assistant who knew how to identify.

"Oh, good." Assistant Wang came back to her senses and immediately stepped forward, and after the identification, she was overjoyed: "Cockroach virus repellent agent, professor, we have succeeded." ”

"Really?" Professor Tan was very pleasantly surprised when he heard this, "Is it really a cockroach virus repellent?" ”

"Well, it's true, it's against the virus that was added at the end and all the viruses that mutated from it." Assistant Wang nodded, his face full of excitement.

"Let's do an experiment with stand-in grass first." Professor Tan suppressed his excitement and said.

Stand-in grass, a special mutated plant found during the clean-up of the base, drips the animal's blood on the stand-in grass, and the stand-in grass will change into the animal's appearance, and completely mimic its state at the time, including people.

However, the person who becomes the substitute grass is similar to a vegetative person, except for the morphological physiological structure and even the lesions, which are the same as humans, but they have no thinking.

After its discovery, it was used in medicine, after all, what could be more suitable than a test subject that completely replicates all of the patient's stand-ins.

Professor Tan took a drop of the blood of an infected patient and dropped it on the stand-in grass, which turned into a humanoid shape, and was covered in red, with black-purple markings all over his body, and was in the fever stage.

Assistant Wang made an identification of the vegetative person: "Stand-in grass-**, state-cockroach virus infection, fever 42 ° ......" She reported the information of the vegetative person one by one.

Song Yi scooped a bottle of potion and gave it to the vegetative stand-in to drink, but there was no reaction at first, but after a while, a large amount of blood suddenly began to emerge from the vegetative man's body, and soon the entire vegetative man was dyed red.

"This, this, this...... Is it a failure? "Assistant Wang is incoherent, it's impossible, could it be that there is something wrong with her identification.

"I remember, the poison that Song Yi got seems to be called Bloody Grass, if a person is poisoned by it, he will run out of blood and die, right?" Professor Tan thought of something and asked.

"Ah," Assistant Wang immediately checked, and sure enough, he saw the name of the poisonous weed, and nodded: "Yes." ”

"Perhaps, this is a normal symptom of this potion, or not necessarily, you can identify the situation for it." Professor Tan pointed to the vegetative person and said to Assistant Wang.

"Okay." Assistant Wang nodded, used the identification for the vegetative person, and then opened his mouth wide: "The cure is successful, and the negative state on its body has disappeared." ”

"And it worked." Professor Tan smiled.

"yes." Song Yi was also satisfied.

After that, they did some experiments, and finally determined that the drug researched by Song Yi and what was added in the end would become a targeted drug for that substance, which could not only treat cockroach viruses.

"This medicine is called a rejection drug." Song Yi named the medicine he had newly studied.

"A great name." Professor Tan said.

The next step is to make more cockroach virus treatment agents as soon as possible, Professor Tan has found a lot of people to make medicines, some are responsible for material analysis, some are responsible for extraction, and some are responsible for learning refining.
