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

In terms of guiding principles: no new impurities can be introduced; the state of matter after separation and purification remains unchanged; experimental operations should be performed first physical and then chemical (simple and easy to implement). These three points have been almost unchanged since their establishment. For solids, liquids, gases, etc. There are dozens of methods for impurities in different states waiting to be tested.

But in the world of Star Warlocks, not only are the experimental conditions immature, but the sparse number of Star Warlocks also delays the conclusion of experimental methods.

Therefore, when Cheng Jinzhou discovered that other star warlocks did not have clear purification rules, he couldn't help but propose that when separating and purifying solids, the methods should start from: heating and burning, heating to sublimation and heating to decompose, and further to dissolution, filtration, evaporation and crystallization ——The gentlemen, including Warlock Jiang Huangxing, were stunned when they heard this.

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

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 and is also an activist. Halfway through the discussion, when he heard Cheng Jinzhou's words, he couldn't help but stand up and said, "I want to do an experiment. Regarding your method choice."

Astromancers like to do experiments because they believe that experiments can lead to true knowledge.

"Although most of them are theoretical issues, of course, if you are willing." Cheng Jinzhou still spoke politely, but he didn't pay much attention to Liao Kai's experiments. The courses he is teaching now, which are about the first year of college, are not only commonly used content, but also have been refined over time. The so-called scientific principles that can withstand the test are much more credible than agents who are landlords.

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

Several astral sorcerers brought their own astral sorcerer apprentices. They originally sat in the back and listened, but now they also helped prepare the experimental materials. Being an apprentice under the name of any Star Warlock is a very lucky thing. If they are willing to work hard and have good talent, they always have a chance to become a Star Warlock. In contrast, for those apprentices who have discovered some skills in astrology but have no one to guide them, it is simply difficult to successfully advance to the level of astrology. Unfortunately, most star warlocks are not very willing to accept apprentices, which makes apprentices have even fewer opportunities to receive normal teaching.

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 happened frequently in the past month or so, and Cheng Jinzhou is used to it. He made himself a cup of lighter sugar tea and drank it slowly - what kind of taste a person likes usually has more physiological reasons than psychological reasons. Children like sweet taste, old people like bitter taste, they want to drink cold water when it is hot, and they want to drink hot water when it is cold... If you just observe the members of the family, you can draw similar conclusions. If they are old enough, people can also find that they have compatible tendencies.

Warlock Jiang Huangxing put more tea leaves. He sipped the hot bitter tea and stood behind Cheng Jinzhou and said, "I rarely see you doing experiments. I didn't expect you to be 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 procedures. As the initiator of the entire team, he also believes that only if he abides by the procedures, others will follow the procedures. The problem caused by this is that he occasionally says a few words too much.

In the eyes of the star warlocks, the few words Cheng Jinzhou accidentally said seemed to be intentional, so they listened carefully. 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 embodiment of the value of the Copenhagen team. . Denmark

Cheng Jinzhou understood Warlock Jiang Huangxing's thoughts and said with a smile: "Did you expect that I also have experimental experience?"

Issues such as purification principles naturally require many purification experiences to be summed up, and his body is only 14 years old. But he didn't need to explain. Astromancers rarely asked about anything other than mathematics. They didn't care and respected privacy.

Warlock Jiang Huangxing smiled and said nothing, acquiescing.

Looking at Cheng Jinzhou's childish face, mature eyes, and the many formulas on the whiteboards around him, Jiang Huang sighed.

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

"Huh?" 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 said "Oh". He had known about this news for a long time.

Jiang Huang sighed and said: "Yang Zhanquan's psychology is uncontrollable. I hope you can try not to conflict with him."

Cheng Jinzhou shrugged noncommittally, but his head didn't move.

"I will not intervene in the dispute between you when the other party is reasonable." Jiang Huang was a little embarrassed when he said this. In just over a month, he gained a lot. But if two level four star warlocks refuse to give in to each other, the consequences will be serious. After all, Cheng Jinzhou stole the materials from the warehouse without permission, and it was only natural that he should return them to the other party. As for the Star Warlocks who want to enter the political arena, the Star Warlocks Association has always been discouraging and not supporting 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 can handle it myself."

He is the priest of the temple. When it comes to the connection with the Star Warlock Association, it is at most a normal Star Warlock. If you want to fight against a fourth-level Star Warlock, you can only go to the temple for such troublesome matters.

His indifference put a lot of pressure on Jiang Huang. He pondered for a while and said: "Yang Zhanquan is a murderous person. Although you are a two-star warlock, he won't care. It's possible. In that case, you'd better stay in the sanctuary. It's better not to anger him."

The temple is guarded by high-level star warlocks day and night, making it the safest place in the capital. The palace cannot match its defensive density and strength. But facing a fourth-level star warlock, one cannot expect much in return for a little defense.

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 face, not to mention whether he can get millions of taels of silver now, he will also face countless obstacles in his life if he wants to farm in the future.

After all, he is different from ordinary astrologers. Those gentlemen who study mathematics and physics can continue their research as long as they stay in the laboratory, get some materials, and at most ask a few people to help. If there are level requirements, they can also Use your savings to buy some special items.

But that's not all he spends money on. Moreover, the benefits of growing real rice and other things are really great.

Cheng Jinzhou thought so and remained silent.

A thick smell floated up from the alcohol stove and instantly filled the room.

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

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

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

Weng Xilian picked up the glass bottle again and put it under the hose. She secretly glanced at Cheng Jinzhou, but was a little disappointed when she saw 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 once, then decomposed and purified them in different ways, and then verified and compared based on the results. More than a dozen people were busy all day long, but not all were completed.

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, Liao Kai and others' experiments were still in progress, but they were also completed.

Xiao Cheng looked at the whiteboard posted on the wall and could guess the results of the experiment based on their expressions. But he asked deliberately: "How's it going?"

"At present, there is no evidence against the principles you set." Liao Kai couldn't tell whether he was convinced or not. In terms of star rating, he is lower than Cheng Jinzhou's. In terms of reputation and status, he is also weaker than Cheng Jinzhou. If he hadn't been older, he would have been convinced by now.

On the other hand, Xiang Xin was rather admiring. He looked at Cheng Jinzhou up and down and asked, "Did you secretly do the experiment on your own? 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 laboratory.
