Chapter 221 Purification and Standardization

In the 21st century, separation and purification actually already have relatively standardized ideas.

In terms of guiding principles: new impurities cannot be cited; the state of the substance after separation and purification remains unchanged; the experimental operation is first physical and then chemical (simple and easy). These three points have hardly been modified since their establishment. For solid, liquid, gas, etc. For impurities in different states, there have been dozens of methods listed for inspection.

But in the world of astromancers, not only are the experimental conditions immature, but the small number of astromancers also delays the conclusion of the experimental methods.

Therefore, when Cheng Jinzhou discovered that other astrologists did not have clear purification rules, he could not help but propose that when separating and purifying solids, the method should start from: heating and burning, heating sublimation and heating decomposition, and further to dissolution, filtration, evaporation and crystallization ——The gentlemen, including Warlock Jiang Huangxing, were all dumbfounded.

Although they will use one or more of these methods, which one to choose and what steps to follow are mainly determined by the astromancer's own feelings.In other words, it is based on the experimenter's preference.

Although Cheng Jinzhou never conducted experiments, his words were precise and precise, which made Bai Jing and others confused.

Among them, Liao Kai is good at solid-liquid transformation, which is also the style of action.Halfway through the discussion, he couldn't help standing up after hearing Cheng Jinzhou's convincing words: "I want to do an experiment. It's about your choice of method."

Astrologists like to do experiments because they believe in experimenting to gain true knowledge.

"Although most of them are theoretical questions, of course, if you want." Cheng Jinzhou still spoke politely, but he didn't pay much attention to Liao Kai's experiment.What he is teaching now, that is, the courses around the first year of university, are not only commonly used content, but also have been tempered.The so-called scientific principles that can stand the test are much more credible than the spies of landlords.

Liao Kai didn't say much, and immediately got ready.

Several astromancers brought their own apprentice astromancers. They originally sat in the back and listened, but now they also helped prepare the experimental materials.It is very lucky to be able to be an apprentice under the name of any star warlock. If they are willing to work hard and have good talent, they always have the opportunity to become an star warlock.In contrast, those apprentices who have learned some astrology skills but have no one to guide them, wanting to successfully advance to the star warlock, it is simply impossible to say.It's a pity that most astrologists are not very willing to accept apprentices, which makes the chances for apprentices to get normal teaching even less.

Although Xiang Xin and Warlock Cao Fengxing trusted Cheng Jinzhou the most among everyone, when faced with practical mathematical problems, their research attitude remained the same and they actively devoted themselves to experimental preparations.Seeing that no one was interested in continuing, Xiao Cheng had to stop the discussion and wait for their experiment.

Similar things have often happened in the past month or so, and Cheng Jinzhou is used to it.He made himself a cup of weaker sugar tea, and drank it slowly—what kind of taste people like, usually has more physiological reasons than psychological reasons.Children like sweet taste, old people like bitter taste, drink cold water in hot weather, hot water in cold weather... You can draw a similar conclusion by observing the members of the family.If one is old enough, one can also discover that one has suitable tendencies in one's own self.

Warlock Jiang Huangxing put more tea leaves. He sipped hot bitter tea, stood behind Cheng Jinzhou and said, "I rarely see you doing experiments, and I never thought you were familiar with it."

The legendary Copenhagen-style discussion is a very in-depth discussion. It is not like a pure chat. In many cases, it will encounter questioning, verification, or current experiments.Cheng Jinzhou strictly abides by the procedures. As the initiator of the entire team, he also believes that only if he follows the procedures, other people will follow. The problem caused by this is that he occasionally says a few words too much.

In the eyes of the astrologists, the few words Cheng Jinzhou accidentally revealed seemed intentional, so they listened carefully instead.And when it was their turn, they either racked their brains to say two meaningful sentences, or revealed two sentences under constant questioning—in fact, the two extra sentences everyone said were the value of the Copenhagen team .Denmark

Cheng Jinzhou understood the thoughts of Warlock Jiang Huangxing, and said with a smile: "I didn't expect that I also have experiment experience?"

Questions such as the principle of purification can only be summed up after many times of purification experience, and his body is only 14 years old.But he didn't need to explain. Astromancers seldom asked about anything other than math and science. They didn't care and respected privacy.

Warlock Jiang Huang smiled and said nothing, it was a tacit agreement.

Looking at Cheng Jinzhou's immature face, mature eyes, and the many formulas on the surrounding whiteboards, Jiang Huang felt emotional.

After drinking the water slowly, he put down the glass and commented in a low voice: "Yang Zhanquan is...a difficult person to get along with."

"Eh?" Cheng Jinzhou didn't expect him to bring it up suddenly.

"He is a fourth-level two-star warlock. He became a fourth-level star warlock very early. The increase in contribution points is confusingly slow. Results reports are often not published in publications such as "Journal of the Chinese Academy of Sciences". Occasionally they are included and cited. The number of times is pitiful." Jiang Huangxing Warlock talked about Yang Zhanquan's experience, shook his head and said: "He has also been on the southwest battlefield, and it is said that he performed very well, and he has killed the opponent's third-level Star Warlock. With the Star God Warrior His likes are not on the same level at all. But in any case, his mathematical ability is highly questionable."

Cheng Jinzhou let out an "oh", he already knew about such news.

Jiang Huang sighed and said, "Yang Zhanquan's psychological comparison is out of control. I hope you can try not to conflict with him."

Cheng Jinzhou shrugged noncommittally, but his head did not move.

"If the other party is reasonable, I will not intervene in the dispute between you." When Jiang Huang said this, he was also a little embarrassed. In just over a month, he had gained a lot.But if two fourth-level star warlocks do not give in to each other, the consequences will be serious.After all, Cheng Jinzhou stole the supplies from the warehouse without permission, and it was only natural to return them to the other party.As for the astrologers wanting to enter the political arena, the Astrologers Association has always discouraged or supported it, and Jiang Huang is no different.

Cheng Jinzhou didn't expect Warlock Jiang Huangxing to say it directly, but he quickly smiled and said, "I'll take care of it myself."

He is the priest of the church.In terms of contact with the Astromancer Association, at most it is a normal one. If you want to fight against a fourth-level astromancer, you can only go to the Holy Church for such a troublesome matter.

He didn't care, but put a lot of pressure on Jiang Huang. He pondered for a while, and said, "Yang Zhanquan is a bloodthirsty person. Although you are a two-star warlock, he won't care about it. It's possible. You'd better live in the sanctuary under the circumstances. It's best not to provoke him."

The sanctuary is guarded by high-ranking astrologers day and night, and it can be said to be the safest place in the capital.The Palace is also inferior to its defensive density and strength.But facing a fourth-level star warlock, a little defense cannot be expected too much.

Hearing the word bloodthirsty, Cheng Jinzhou trembled inadvertently.He is not a steadfast and unyielding preparatory martyr, nor is he someone who will risk his life when his brain gets hot. He values ​​his own life very much.The problem is that if he backs down, he will not only lose his face, not to mention whether he can get millions of taels of silver now, and there will be countless obstacles in his life if he wants to farm in the future.

After all, he is different from ordinary astromancers. Those gentlemen who study mathematics can continue their research as long as they stay in the laboratory, get some materials, and at most invite a few people to help. Use your savings to buy some special items.

But that's not the only place where he spends money, and the benefits of planting real rice and other things are really too great.

Cheng Jinzhou thought so, but didn't say a word.

A thick gas rose from the alcohol stove and permeated the room in an instant.

Liao Kai recorded loudly there: "Thermal decomposition, no solvent is used, now the gas is collected and the purity is measured."

The first requirement of purification is not to change the nature of the substance, which is also one of the signs to judge whether the experiment is successful.

Several star warlocks once again devoted themselves to the vigorous wave of experiments.

Weng Xilian picked up the glass bottle again and put it under the hose.She peeked at Cheng Jinzhou, but was disappointed to see him looking down at the book in his hand.But even she herself didn't know what she was disappointed about.

……

In order to make the results universal, Guo Kai selected more than a dozen known compounds at one go, then decomposed and purified them in different ways, and then verified and compared the results. More than a dozen people were busy all day, but they did not complete all of them.

Star Warlocks are all energetic masters, and they don't even want to sleep until they finish their work.Although Cheng Jinzhou's physical fitness has improved, his ability to stay up late has not been developed in advance, so he simply goes to bed early.

When he got up the next morning, the experiment of Liao Kai and others was still going on, but it was also completed.

Xiao Cheng looked at the whiteboard pasted on the wall, and looked at their expressions, and he could guess the result of the experiment.But deliberately asked: "How is it?"

"At present, there is no evidence against the principles you set." Liao Kai couldn't say whether he was convinced or not.In terms of star rating, he is lower than Cheng Jinzhou's, and in terms of fame and status, he is also weaker than Cheng Jinzhou. If it weren't for being older, he would have been convinced by him long ago.

On the contrary, Xiang Xin had a taste of admiration, looked up and down at Cheng Jinzhou, and asked, "Did you do the experiment secretly yourself? While we were away?"

Cheng Jinzhou laughed with admiration.It feels a bit like facing a junior girl again - by the time girls reach their senior year, they will be too smart to be cute.

Smoke continued to fill the lab.
