"When you enter the lab, let go of all your imagination as if you were taking off your coat – because you can't be sloppy in the experiment. A careless operation can lead to a catastrophe in a chemical lab. But when you do scientific research, you have to spread the wings of your imagination so that you can have a better tomorrow. All scientific results come from genius fantasies. Chai Rumei seems to have completely come out, and the change in personality makes it a little difficult for all the students to adapt.

"Mr. Chai, what's wrong? Menopause is over? Not to mention, Mr. Chai's appearance, with his temperament at this time, is really a perfect beauty. Chen Dongcai said.

Zhang Shanhai smiled and didn't speak, only he knew best why Chai Rumei had undergone such a huge change. Zhang Shanhai listened very carefully to this class, not because he was embarrassed to skip class after getting acquainted with Chai Rumei. Rather, he seems to have learned some ideas about alchemy from this chemistry class. The process of alchemy is very similar to that of chemical experiments. Chai Ruxue's words just now are also correct when applied to the alchemist.

Chemical processes are very dangerous, and the slightest mistake can lead not only to the failure of an experiment, but even to an even more dangerous situation. The alchemy process is even more sinister, because once the alchemy process is not careful, if the furnace is fried, it will be a disaster. I don't know how many alchemists died in the process of frying the furnace.

The process of scientific experiments has a set of strict procedures, and each step of the experiment will have very strict requirements. However, as long as the operating procedures are strictly followed, the experiment can generally be successful.

When the experiment began. They each received the medicine, and the experimental procedures were pre-studied by everyone, so it was not too difficult to operate.

But in the process of doing the experiment, Zhang Shanhai was ingenious and randomly took concentrated chemicals and added them to the aqueous solution. Not every chemical can be dissolved in water, so the aqueous solution in the beaker naturally becomes cloudy.

"Mountains and seas. What are you doing? If you let Mr. Chai see you coming nonsense, you will be unlucky. Chen Dongcai asked.

"It's fine. Don't just look at me all the time, or else. Looking at you like this, everyone knows that I am famous here. Zhang Shanhai said.

In fact, Chai Rumei saw Zhang Shanhai's change here at the beginning, but she was a little conflicted. Should it be managed or not? This Zhang Shanhai is different from other students, he is very mature and shouldn't do something boring, but it seems, no matter how you look at it, this Shanhai doesn't look like he's doing serious things. However, she still couldn't help but ignore Zhang Shanhai's affairs and let Zhang Shanhai operate it by himself.

Zhang Shanhai stirred several mixtures in the beaker for a while, but these insoluble substances were still suspended in the water. Zhang Shanhai recited an ablation spell, several insoluble substances in the beaker. It dissolved strangely slowly, and soon the beaker turned into a glass of water.

"Hey, Shanhai, did you add sulfuric acid just now?" Chen Dongcai said.

"Well, a little bit more." Zhang Shanhai said.

"Huh. I don't know what you've become here. Chen Dongcai said.

When Zhang Shanhai and Chen Dongcai's attention shifted to other classmates, he played another spell and became a pill. The contents of the beaker automatically gathered up, and the water slowly evaporated, leaving a few small beads of crystal clear in the beaker. I don't know what substance it is, but this bead is really cute.

"Huh. What did you get? Sheng Weigang had already finished the experiment, and it was very strange to come over and see a glass of glass beads in Zhang Shanhai's hand.

"It's nothing, I washed a few of my glass beads with sulfuric acid. There was some dirt on it, so I just took advantage of the experiment to wash it with sulfuric acid. Zhang Shanhai said. …,

"Yours is the case. These beads of yours are really beautiful. Not like glass in general. It's the same as the orb. Sheng Weigang said with a smile.

Zhang Shanhai felt quite satisfied, no matter what he got, the most important thing was that he found that the spells used in alchemy were actually feasible to use for chemical experiments. Secretly put a few beads from the beaker into the mustard seeds of Sumeru, and then pretended to do the experiment again.

Chai Rumei had been watching Zhang Shanhai do experiments, but she didn't expect that after he randomly added several substances that could not react at all and mixed them in the beaker, not only could they be dissolved intact, but also a few strange beads could be obtained in the end. The most incomprehensible thing is, where did the original aqueous solution in the beaker go? Even if water were involved in the reaction, the volume of the synthetics that should not be produced could be reduced so much. No experiment was able to produce such results.

When Chai Rumei saw this scene, she was very surprised, but she was silent on the surface, and waited until the end of the experimental class before she said, "That's all for today's experimental class." Ask the squad leader to arrange the students on duty. In addition, please ask Zhang Shanhai to stay. ”

"Boss, what did I just say about yours? Don't mess around! You just don't listen. Teacher Chai must have seen it in her eyes, I just saw her glance here from time to time, what you have done, she must have seen it in her eyes. I think she's thinking about getting you in trouble. You're going to be in for a bad luck this time. Chen Dongcai said.

"Shanhai, you come to the preparation room." Chai Rumei's voice came again.

Zhang Shanhai walked over.

Chai Rumei walked to the door and closed the door.

The students who were engaged in sanitation outside thought that Chai Rumei would criticize Zhang Shanhaiguan inside. It doesn't seem to be the same as before. Now I know how to take care of the student's face. used to be in front of everyone, Chai Rumei started scolding.

"Zhang Shanhai, thank you so much last time. Now my husband and my son are getting better. We bought a house and were ready to move in a few days. Chai Rumei said.

"Hehe, that's the best, or I'm worried that you'll have problems living there." Zhang Shanhai said.

"I have one more question, how did you do that?" Chai Rumei asked.

"What and how?" Zhang Shanhai didn't understand what Chai Rumei said.

"After you started adding a few water-insoluble substances to the beaker, how did you get them to dissolve?" Chai Rumei asked.

Zhang Shanhai smiled, "This, I used some means that ordinary people can't do." ”

"Really? Can you show me those products? Chai Rumei asked.

"What's wrong with that? But it's best not to talk about it. Zhang Shanhai said.

"I know that." Chai Rumei said.

Zhang Shanhai put his hand into his pocket, and after a while, he took out a few beads from his pocket.

Chai Rumei took the beads from Zhang Shanhai's hand and looked at them several times in her hand, "This bead is really beautiful, like a gem." ”

"If you like it, I'll give it to you. Anyway, I'm just messing around. Zhang Shanhai said.

Chai Rumei smiled, "Then thank you." ”

Let's say that after Cao Leijun returned to the army to report, he immediately received an urgent task. Ke Shanfeng, a key scientist on a scientific expedition, disappeared from the desert in western Xinjiang. Cao Leijun was asked to immediately bring a special team into the desert to search. Although the chances of survival of these scientists are extremely slim, any one of the scientists on the scientific expedition is a great asset to the country, and from a political point of view, no one can give it up. Although it is possible that the cost of carrying out a rescue is higher. …,

The situation there was unknown, and Cao Leijun immediately rushed to the western frontier with a dozen or so soldiers, and a few days later, he joined the scientific expedition team.

"Teacher Ke said that day that he was going out to relieve himself, but after he went out, he never came back. Sensing that something was not quite right, we immediately searched the surroundings, but it was too late to find him. So, there was no way, we had to report to our superiors. Ke Shanfeng's student Hu Baoyong said.

"I have a question. Why don't any of you have any experience in the wilderness? If such an important scientific expedition is being conducted, why is there not a single security officer? If you can contact the army in advance to send a special protection officer. Probably no longer have such a problem. Cao Leijun said.

"Who would have thought that such a thing would happen? Our equipment is in good condition. If it hadn't happened to me, there wouldn't have been a problem. Besides, we have been conducting expeditions for so long, and what happened when we were about to return shows that there is not much problem with our survivability. Hu Baoyong said unconvinced.

"But, in the end, one of you went missing. And the most important person in your team. I heard that all the data is in his hands. If something so big happens, which of you can afford to take responsibility? Cao Leijun said.

"We have our share of responsibility. However, I think that it is useless to say more, and it is better to find someone first. Maybe he can save Mr. Ke back. Hu Baoyong said.

"Now that all this time has passed, do you still expect him to survive? I think it's almost enough to be able to find the body. Cao Leijun asked.

"Why not? Mr. Ke is the most survivable member of our team, so even if he gets lost, he should be able to survive with his extraordinary ability. But the more time passed, the slimmer chance of Mr. Ke's survival became. Hu Baoyong said.

"Okay, let's stop talking nonsense. We are now starting to develop a plan to save lives. I need your travel map for the past few days, and then conduct a step-by-step investigation from the place where Mr. Ke disappeared. Until someone is found. Also, you'd better tell us everything you know. This will facilitate the search for Mr. Ke. Cao Leijun said. (To be continued.)
