There was a bustle outside, but Lee Sang-hyun in the laboratory had a gloomy face, there were less than three days left, and he had successfully reached 96% of his proficiency, and it could almost be said that he could finish his studies after completing the last few experiments.

However, things often did not go as smoothly as expected, and he was following the steps instructed by Dr. Annan in an orderly manner, and the last step of the antidote was about to be successfully made, when he was about to put the last reagent into the experimental solution, only to find that the new reagent was completely separated from the experimental solution by air.

"Teacher, will there be a problem with the last step?" Li Xiangwei looked at Annan beside him suspiciously and asked.

Annan had been observing his movements, shook his head and said, "It's a standard approach, and there is nothing wrong with it. ”

"But ......," Li Xiangwei said as he picked up the test tube with a test tube clamp and put it in front of Annan, "but teacher, why is the last reagent suspended?" ”

Hearing this, Annan picked up the glasses on the side and put them on, carefully observed the reagent in front of him, frowned and said: "Impossible, although I haven't done this experiment myself, but an old friend of mine told me that it is feasible to do so, and he is also an expert in this field, so he shouldn't be wrong." ”

The two of them looked at this very strange bottle of reagent and scratched their ears and cheeks for a long time, and they didn't know what was going on, and just when they were at an impasse, Annan suddenly remembered that there was a sealed book in his cabinet, which was full of Western fantasy, and he refused to believe it as an atheist anyway.

He was ready to gamble that maybe there would be an answer to that in that book.

Walking quickly to the cabinet, he took out a rusty key from his coat pocket and opened it, and a musty smell instantly hit him, carrying a lot of dust.

Annan pinched his nose and flipped through the dusty book from the cabinet, and he simply wiped the dust off the surface, and a smell of history came to his face.

He patiently rummaged through the table of contents, and suddenly saw a chapter titled "The Suspension of the Laboratory", and his heart was very excited, and he hurriedly greeted Li Xiangwei, who was still looking at the test tube.

"Xiangwei, come here!"

Lee Sang-hyun put the test tube back on the shelf, and then ran over and asked, "What's wrong with the teacher?" Did you find anything? ”

"Well, I pretty much understand what's going on." Annan nodded and said, then handed the book to Li Xiangwei, "Look at this page, test your understanding." ”

Li Xiangwei took the book, forcibly endured the choking smell of moldy ash and looked carefully at that page, and suddenly a scene appeared in his mind along with the reading.

This scene is a laboratory, a person is conducting an experiment, suddenly there is a situation of two liquids suspended, I saw that the person unhurriedly dripped a drop of black liquid, and then the two separate solutions quickly fused to make a new type of drug.

"Teacher! I see, there's a medium missing between the two solutions, and that medium is this black liquid. Li Xiangwei patted his head and reacted.

Annan nodded, but did not continue to show a happy expression, but said with a heavy face: "However, we don't know what this black liquid is. ”

"Teacher, there must be a limited variety of black liquids, so let's sift through them carefully, which can be used as a medium to show that this substance must have special properties." Li Xiangwei said tentatively, in fact, he is not sure that this nature will not exist.

The two of them began to sift through the black liquid they were familiar with, taking out some of the experimental solution and dropping it into many test tubes as experimental droppers, and then dropping the black liquid into different experimental test tubes one by one, but none of these liquids had any adhesive properties.

This is undoubtedly a huge blow to them, the closest to collapse is Lee Sang-hyun, time is getting less and less, if the task is not completed, he has no way to continue.

The sun gradually set, and Dr. Annan went back to his room to sleep because he was old and his body couldn't support sleeping late, and before leaving, he asked Lee Sang-ho not to work too hard, as long as he did his best.

Li Xiangwei nodded, but the stubbornness in his heart could not allow him to give up, this was not his character at all.

The whole person was immersed in the test, and halfway through Lin Yimo knocked on the game pod to let him go offline to rest, he just drank some water casually, ate some bread and returned to the game.

......

A boiling sound came from the test tube, and Li Xiangwei hurriedly came to it and stared at it, constantly chanting in his heart: "Success, success!" However, the result disappointed him, and after boiling for a while, the two solutions were suspended again, and there was no sign of fusion.

Distraught, Lee Sang-hyun knocked over the contents on the table, and a bottle of ink was shattered on the table, and the spilled ink happened to drip into the test tube of the official experiment.

He was very unhappy, and this one was likely to invalidate all the results of his previous experiments. He endured the heartache, picked up the test tube and tried to pour the liquid into the pool.

To his surprise, the two solutions magically fused together silently, and the experiment was successful!

[Hint: Congratulations to players for successfully mastering the rules of the "NAK Virus" and creating an exclusive antidote.] 】

He glanced at the subclass's skill proficiency at 98%, and there was one last experiment left, as long as it was completed in the next two days.

"Ahem......"

A strong cough came from Annan's bedroom, accompanied by the sound of nausea retching.

Li Xiangwei was shocked, ran to the bedroom door quickly, knocked on the door and asked, "Teacher, how are you?" ”

After a while, Annan's coughing voice stopped, and a somewhat vicissitudes of life and a weak voice said: "It's nothing, it's just that there is some discomfort in the throat, just drink some water, you go to bed first." ”

Li Xiangwei was still a little uneasy, and hurriedly found the key to the door to open it, and saw that Annan on the bed was hurriedly arranging the quilt, as if he was covering up something.

"Teacher, what are you doing?" Li Xiangwei asked a little uneasily.

Annan lay down and covered the quilt and said, "It's nothing, I accidentally kicked the quilt to the ground just now, it's nothing, you can get out quickly." ”

"Alright then, you have a good rest." After Li Xiangwei finished speaking, he closed the door and went out.

Seeing that the door was closed, Annan gently lifted the quilt, crumpled a pile of bloodstained paper, lit a candle and burned it all, sprayed a little fragrant perfume, and after making sure that there was nothing unusual, he lay back on the bed and continued to sleep.

......

And in a bedroom far away in the real world, a person can't sleep for a long time.
