Cao Leijun and Li Moran hosted Zhang Shanhai a few more times, and Zhang Shanhai and their uncle and nephew slowly became acquainted. Cao Leijun bought a few talismans here in Zhang Shanhai, everyone is familiar with each other, and the money still has to be spent. Cao Leijun and Li Moran's family is not short of money. Although the Cao family and the Li family are both official families, there are many people in the family who do not like officialdom and choose to do business. In a family like this, as long as people are not too stupid and do any business, they can make a lot of money.

Cao Leijun soon ended his vacation and returned to the army. Li Moran, the son-in-law, also had to run his business, so Zhang Shanhai calmed down and had time to study the art of alchemy. It just so happens that Zhang Shanhai is studying engineering, so naturally he did not go to the laboratory to do all kinds of experiments, although the domestic experimental conditions are relatively backward, but Yanda is an exception, through the efforts of some people, the experimental instruments in the laboratory are still relatively advanced.

Zhang Shanhai felt that this chemical experiment actually had some things in common with alchemy. For example, some chemical experiments need to be heated, or catalysts need to be added, or other conditions must be met before the reaction can occur. Alchemy also needs to be heated, and the following auxiliary substances need to be added to it, and at the same time, it also needs the necessary spells to control it, and finally it can become a pill. So in fact, the two may be mutually reinforcing. Chemical reaction, it is precisely because of the thermal movement of the molecules that make up the chemical substances, those molecular groups are recombined to control the way of molecular movement, so that the results of the reaction can be different, and the alchemy process is the same, the essence of the medicine in the pill is also moved in a certain way of motion, and the heat and spell are used to control the movement of these pill essences. The movement pattern is well controlled. Then in the end, it can be refined into a high-quality elixir.

"Zhang Shanhai, your kid was discovered by the teacher for skipping class in the past two days. This time, the chemistry teacher Chai Rumei can make a special mention of you, saying that if you don't show up in the classroom today, no matter how good you are in the final exam, you won't want to pass. Sheng Weigang told Zhang Shanhai a not-so-good news.

Chai Rumei has a nickname among Yan University students, that is, Jin Yong's character "Extermination Master". It is said that this person has been in menopause for a long time, and her temper is extremely eccentric. The students of Yan University are all proud sons of China. Take this Yan University diploma out, and you can find the best job casually. But if you fail the course, it will be a big trouble. When I graduated. I can't get a diploma. I can't assign work, and I can't go out and find a job on my own. For many people who want to mix up a diploma, Chai Rumei is the real-life version of the extermination master.

"Oh well. Nothing happened today anyway. It's nothing to go to class. Perhaps, learning a little bit of chemistry will help alchemy. Zhang Shanhai said in his heart.

"Okay, I'll pamper the Extermination Master today." Zhang Shanhai said with a smile.

Chen Dongcai said, "Boss, you can be careful. Mrs. Shi is dissatisfied now, and the temper of menopause is big, your kid's body is so weak, be careful to be sucked clean. ”

In the dormitory. Zhang Shanhai is also used to talking to these spring guys about some topics with a stronger taste. If the people on the road see that Zhang Shanhai is so in the bedroom, he is afraid that his glasses will fall sharply. Still, it seems. The monks have not found any examples of nearsightedness and farsightedness.

Sure enough, Mrs. Shi began to roll call in the classroom, and when Zhang Shanhai should "arrive", Mrs. Shi was stunned and looked at it several times with her glasses.

"Ouch, Zhang Shanhai is here, rare guest!" Chai Rumei said.

"The main thing is that Mr. Chai's class is full of interest. I stopped for a few days and didn't come, and I regretted it, so I decided to change my mind and become a new person. Zhang Shanhai said it exaggeratedly. The classmates couldn't help but laugh. …,

Chai Rumei also smiled, "It's useless to just talk about not practicing." Listening to the smiles of the classmates, you know that you are not sincere at all. But I warn you, you've missed most of your classes this semester, and you're going to have lab classes next week, so if you're still missing, don't think about chemistry this semester. Even if you score 100 points in the final exam, I won't let you pass. Chai Rumei knew that Zhang Shanhai's results were good.

"Teacher Chai will wait and see. I Zhang Shanhai said to do it. Zhang Shanhai said.

When Zhang Shanhai said this, he was carefully looking at Chai Rumei's face. Of course, it's not because of Chai Rumei's beauty, with Chai Rumei's age, no matter how beautiful she is, she is still a. Naturally, there is no lethality to Zhang Shanhai. What Zhang Shanhai was interested in was that this Chai Rumei's body actually exuded a trace of black gas, which was obviously an evil demon entering the body. Fortunately, it was Zhang Shanhai just now, who was upright, and suppressed the evil qi in Chai Rumei's body, which made Chai Rumei's performance very different from the usual paragraph.

But others are not as lucky as Zhang Shanhai.

Gu Qun plagiarized the homework of other classmates, and was named by Chai Rumei on the spot, and reprimanded loudly without mercy.

"Plagiarism is an extremely shameful act. As a student of Yan University, you should be strict with yourself. We will resolutely put an end to such acts. When you are on campus, you can copy homework and papers, and when you go out into society, you can cheat. I hope that there will be no more such behavior in the future. Chai Rumei said.

Gu Qun was stunned, this person is really angry compared to people, Zhang Shanhai skipped class for three days, and he didn't even say a few words without itching or pain, and when he came to himself, he just copied someone else's homework, but he accidentally copied a typo. It was so criticized.

"Teacher Chai, has he been so angry lately?" Zhang Shanhai asked.

"Not yet? But it's really weird, in the last class, she also said that she would deal with you seriously. But I didn't expect her to just say a few casual words and let you go. There's something weird about this! Mrs. Shi really likes you! Sheng Weigang said.

"Sheng Weigang! Speak, go outside, speak. It's too unusual. I often talk in small words in class. Chai Rumei's ears seemed to be particularly sensitive, and she could hear her clearly when she sat in the last row and spoke so quietly.

Sheng Weigang glanced at Zhang Shanhai resentfully, but did not speak, but the meaning in that expression was very obvious: See? It's okay for you to speak, as soon as I opened my mouth, Mrs. Shi went crazy.

After class, Zhang Shanhai was about to skip class again, so he took the book and walked outside the teaching building.

"Hey, old man, where are you going? Isn't the next math class right here? Sheng Weigang asked.

"I'm going to have something." Zhang Shanhai said.

The people in the class were accustomed to Zhang Shanhai skipping class, Sheng Weigang smiled, "You don't want to be a new person?" ”

"I mean starting tomorrow." Zhang Shanhai said with a smile.

When Zhang Shanhai walked out of the teaching building, Chai Rumei had already walked far away. The strange thing is that this Chai Rumei did not go in the direction of the office, nor did she go to the teacher's dormitory, let alone outside, but walked to the lake.

"What is she doing over there?" Zhang Shanhai was very strange, so he followed.

There is an ancient pagoda by the lake, which is said to be a water tower used to supply water to Peking University, and it was ingeniously designed as a pagoda. However, Zhang Shanhai felt that the main function of the pagoda was not so much to use as water supply, but to suppress feng shui. It is the finishing touch of the Yanyuan Feng Shui Bureau. It is also one of the reasons why Yanyuan has gone through twists and turns, but it can be passed down from generation to generation and prosper.

This tower level 13, 280 feet high, 104 feet circumference, hollow, only 37 meters high, 164 feet deep, water spray more than 10 feet above the ground. Water from the well comes out of the ground. The spring water gushes out of the ground, and it naturally connects with the earth. If you don't use pagodas to suppress it, it will inevitably be easy to breed ghosts here. But even so, the evil aura often leaks out. So much so that over the years, quite a few people have committed suicide in this lake. …,

This Chai Rumei didn't notice that someone was following behind her, and walked straight towards the ancient tower. He went to the bottom of the ancient tower and found a stone and sat down.

If this seems to ordinary people, there is nothing special about it. The lake has always been one of the favorite holy places for Yan students.

But when Zhang Shanhai took a look, he saw wisps of black gas leaking out from a gap at the bottom of the tower and flowing to Chai Rumei, who was sitting at the bottom of the tower. After absorbing wisps of black qi, Chai Rumei seemed to be very comfortable, with a very unfinished look.

Zhang Shanhai knew that this Chai Rumei had been invaded by the yin evil, and if she continued, she would definitely be completely controlled by the yin evil, and at that time, there would be big trouble.

Since it has been encountered, it is natural that it cannot be ignored.

Zhang Shanhai walked over, and Chai Rumei was not as friendly to Zhang Shanhai as she was in the classroom.

"You're not in the classroom, why are you here?" Chai Rumei said.

"Teacher Chai comes here every day?" Zhang Shanhai asked.

"The teacher's affairs need to be taken care of, so you better hurry back to the classroom and go to class!" Chai Rumei said.

"This extreme yin earth qi seems to taste good." Zhang Shanhai said something inexplicable.

"I, I don't understand what you're talking about?" Chai Rumei said.

"I think when people die, they shouldn't stay in the world, let alone go to other people's bodies. If you go on like this, you will not only harm others, but also yourself. You won't be able to enter reincarnation in the future. Zhang Shanhai said.

"You can see it." Chai Rumei said.

"Why are you possessing Teacher Chai?" Zhang Shanhai asked.

"It's none of your business." Chai Rumei said.

"I don't think you're harmful, so I'll be kind to you. Otherwise, your soul will be scattered, and you will never be able to be reborn. Zhang Shanhai said.

"At such a young age, he can only talk big. You're just a student who doesn't know how to learn. I can't manage my own affairs well, and I even take care of other people's affairs. Chai Rumei said.

"Really? Well, I'm too lazy to talk nonsense with you. Zhang Shanhai took out a ghost-detaining talisman that was as black as ink, ready to directly clean up the ghost attached to Chai Rumei's body.

As soon as this ghost talisman came out, the yin ghost immediately recognized it and hurriedly begged for mercy, "Daxian spare his life, and his subordinates are merciful." I also had to do it as a last resort. (Your support is my biggest motivation.) )
