Xu Yunshu was already fully mentally prepared for Professor Xue's inability to study anything from the sample.

Half of this kind of thing depends on strength, and the other half depends on luck.

If Professor Xue can study any tricks in this short period of time, it is estimated that he has loaded the template of the protagonist of the academic tyrant, and since then he has started the journey of brushing papers and awards.

However, listening to Professor Xue's tone, it seems that the experiment is still progressing?

"Professor Xue, can you tell us about the specific situation? Almost a little bit...... What is the difference? Xu Yunshu asked.

"It's really just a little bit close." Professor Xue wiped the sweat from his head and replied, "It's just that the current samples have been used up by us, so you know, we don't need to use the soil in the corner of the forest, we only need the ones outside the forest." ”

Xu Yunshu frowned, listening to the meaning of Professor Xue's words, they should have found something, but they were not sure and needed additional samples.

It's just that every time he makes a sample, he loses a lot of energy, and if he makes it continuously in a short period of time, the burden on his body is too great.

He can't do what others say.

Xu Yunshu needs to weigh whether it is worth it.

If this "just a little bit short" is really "only a hundred million points away", he might as well go back to the Dream Forest again and find another way to solve this matter.

Or it's better to give up altogether.

"Professor Xue, I want to know where the experiment is going, just tell me the results."

Professor Xue scratched the gray hair that didn't have much left, hesitated for a moment, and said: "In the analysis and comparison of the two samples, we found fourteen complex organic substances that exist separately, and the other substances are similar, although there is a slight difference in percentage, but there is no statistical difference. ”

Xu Yunshu nodded.

In other words, if there is really something to restrain parasites, I am afraid it is on these dozen or so complex organic substances.

"The problem was that there were so few samples that we couldn't confirm which macromolecule was an effective insect repellent. Another difficulty is that although we can try to simulate the composition and structure of each macromolecular organic substance on the computer, there is no technical means for effective preparation in a short period of time. ”

Xu Yunshu understood that all the problems stemmed from the lack of firepower - phew, insufficient samples.

With his current physical condition, he could indeed make a soil sample outside the forest again, but compared to this, Xu Yunshu was more curious about the sample that Professor Xue had separated.

He vaguely felt that there should be a more convenient solution to this matter.

"Can you show me what has been separated?" Xu Yunshu thought for a moment and asked.

Professor Xue was stunned and nodded in agreement.

He still has requests for others, and naturally he responds to them.

After changing into a new isolation gown, Xu Yunshu re-entered Professor Xue's laboratory.

As far as the eye can see, in the fume hood, there is a row of test tube racks, on which are neatly arranged fourteen test tubes with transparent solution.

He paced over, leaning down, and scannying the liquid in the tube.

Just by appearance, you can't see the difference between them.

These tubes are 25 ml in size, with clear solutions occupying only the very bottom of them, and each of them is only two to three milliliters shallow.

This also includes the experimental agents used to extract and refine them.

In this way, it is true that there are very few samples available for study.

Professor Xue stood aside, pointed to the label attached to the test tube, and introduced to Xu Yunshu: "As long as I can get a new sample, the next step will be very simple." ”

"You see, what is placed in these test tubes is the special macromolecular organic matter that we have extracted through comparison. Numbers 1 to 8 are extracted from the soil in a corner of the forest, and theoretically they should not have the effect of repelling insects, but on the contrary, these organic matter should be closely related to the pupa of insects in the ground. ”

His finger swiped to the other side, pointing to the remaining samples on the test tube rack, "Starting with solution No. 9 and ending with No. 14, these six organics are the key to our future research." ”

Xu Yunshu followed Professor Xue's fingers and focused his attention on the six samples.

As it stands, they "maybe" have an anthelmintic effect, but they need to be further proven experimentally.

The problem is that each of the extracted solutions is extremely rare, and if you use them for experiments, if the experiment fails due to too small a dose, it is still impossible to determine which substance can restrain the parasites.

Or none of them are the key to restraint.

There are many variables, and a solution of less than five milliliters is too few.

Therefore, the shortcut that Professor Xue could think of was for Xu Yunshu to "bring" some samples for them to separate and extract in case of emergency.

Honestly, that's one way to do it.

Consume energy again, make soil samples, let Professor Xue continue to separate, find out the substances that are really effective against parasites, and then after Xu Yunshu returned to the Dream Forest, he used the powerful potential of the white wolf's body to prepare a large number of insect repellent drugs, and used it as a weapon to go deep into the corner of the forest.

Everything seems to be in place.

But Xu Yunshu did not act for a long time.

He did not mention to Professor Xue that he would go back to "take" the soil samples, nor did he make the samples on the spot.

Xu Yunshu just leaned over and stared at the six samples in front of him quietly.

Professor Xue, who was standing on the side, was a little puzzled, stopped explaining, and looked at him with a pair of cloudy old eyes, not knowing what he wanted to do.

Professor Xue was old and frail, and when he worked all night continuously, his body could not support him and he could not stand for a long time.

But now is the time to ask Xu Yunshu, it is inconvenient to find a place to sit, so he can only barely support it, and asks, "Xiao Xu, what are you looking at?" If there is any difficulty, you may wish to raise it and we will see if we can solve it. ”

"By the way, didn't the security officer surnamed Pi go and call a one-star dish certified by the tire factory? He is a graduate of the capital, how can he know what is delicious in this city, so I will tell the students to go ......"

"Professor Xue, there's no need to break the bank."

Xu Yunshu heard Professor Xue's words, and felt that his image seemed to have changed slightly in the eyes of others, so he had to explain with a smile, "As long as it is high-energy food, you don't have to look for restaurants with high added value." ”

"So, you agreed?" Professor Xue's eyes lit up.

Xu Yunshu was stunned and understood the meaning of Professor Xue's words, and then made a disappointing move.

He shook his head resolutely.

Professor Xue was immediately disappointed.

Immediately after, Xu Yunshu's words came into his eardrums.

"I don't think it's just in the real world."

Professor Xue was stunned for a moment, looked up at Xu Yunshu, and didn't know what this sentence meant.

Xu Yunshu straightened up, turned his head to Professor Xue and asked, "Are the solvents used to extract these organic matter toxic?" ”

"It's not too toxic, but if you accidentally touch it or take it by mistake, it will definitely have an impact on the body, and gastric lavage is inevitable." Professor Xue responded.

Xu Yunshu nodded, "Since that's the case, then I'll rest assured." ”
