"All those who have taken my class know that my class will be held for seven consecutive days at a time. As for when the next seven days will start, and waiting for notifications. If you have any objections to this schedule, it is still time to withdraw from the class of other teachers. If no one wants to withdraw, then start the class now." Vivian sat on the raised stool on the podium with a serious face, and leaned against the side of the podium, which never left her body: "This year I am talking about the cutting and synthesis of crystal stones. According to convention, before starting the lecture, it is three minutes to ask questions. Who has any questions? Now ask."

"Teacher Vivian, I have a problem." A fat boy dressed in plain clothes and acne-faced face was the first to stand up: "Master, why didn't your bodyguard sister come today?"

"What do you want to do?" Vivian lowered her head, raised her eyelids and stared at the fat man with a cold look: "I really disappointed you. I've changed people today, I'm a man."

"Oh, Hubert is on." The little fat man covered his chest with his hands and screamed, and collapsed weakly on the chair: "Who will save my broken heart."

"Don't worry, I remember you, Kuba, right?" Vivian pointed to the fat man: "See you during the exam."

"Teacher, I'm wrong, please forgive me." The fat man put his forehead on the table and kowtowed: "Please forgive me."

"Report to the teacher, I have a problem, too." A girl dressed in cool and heavy makeup stood up the second time: "Master Vivian, your new male bodyguard..."

"You don't need to know him." Vivian interrupted with a headache.

"No, no, teacher, I don't want to know him." The girl waved her hands and said in a strengthened tone: "I want to know, is the male bodyguard you mentioned? The wretched uncle who was pressing his face against the window and rubbing against the window with a lustful look on his face and staring at every girl's thigh?"

"Haha, haha, haha." Vivian's mouth twitched, and her neck twisted little by little towards the girl's finger. The staff had been copied in his hand at some point and pointed out the window: "Dear Mr. Pannis, are you coming in and sitting in the last row and waiting, or will I help you fall from the sixth floor and enjoy the joy of flying?"

Panis opened the window and rushed in, sitting in the last row of empty seats, looking straight ahead without looking squinting, as if nothing had happened just now.

"Since there are no other serious problems, I will start teaching." Vivian cleared his throat and said, "I won't talk about the most basic things, such as what crystals are and how to use crystals. If you don't even know these, please go back to the junior class to re-exercise."

"Let's get to the point, everyone should be clear that the discipline of crystal cutting and synthesis is a high-risk discipline, both property risks and life risks, which are terrible. Crystal cutting mainly bears property risks, while crystal synthesis mainly bears life risks. Therefore, if you are planning to use the Crystal Energetic School as the main school, you must be clear, clear, and then clear about this."

"As the name suggests, this discipline includes two aspects: crystal cutting and crystal synthesis. If you want to learn these two aspects, you must understand the secrets inside the crystal. To put it simply, the crystal is an unstable energy system. The higher the energy contained in it, the stronger the instability. Therefore, the higher the energy, the more likely it is to escape energy, and the dissipation is irreversible. If you have a crystal of 20,000 ter, then first of all, you need to congratulate you on having a wealth of more than 80,000 gold coins. However, maybe it is just a slight knock collision, or maybe it is just a simple room temperature rise, and your 80,000 gold coins may completely disappear."

"Some students noticed that I mentioned the crystals of 20,000 terres. Why must it be 20,000, not 30,000? Because the threshold for energy dissipation of naturally formed crystals is 20,000. Once the internal energy exceeds 20,000, it will immediately dissipate, without exception. Therefore, any crystals of more than 20,000 terres are artificial, and the method of manufacturing is the crystal synthesis we will talk about below."

"Who will tell me what if I want to synthesize a 40,000 terite crystal?" Vivian glanced at the students who were ecstatic.

"It is made of two 20,000 terite crystals." The quick-responsive student immediately answered.

"Okay." Vivian pointed to the answering student and said, "I played with building blocks when I was a child. Now I give you 40,000 blocks to build a castle. Do you divide them into two groups, each into two upper and lower parts of 20,000 yuan each, and then stack them up, or is it easier to build them up bit by bit?"

The student who answered lowered his head and stopped talking.

"Actually, your answer is correct in theory. Because every time the crystal is synthesized, no matter how many terres of crystal added, even if there is only one terre, it will cause a significant reduction in the stability of the target crystal. Therefore, the higher the energy of the crystal is added, the better. However, the higher the energy, the more unstable it is. Just like the building blocks mentioned earlier, it will be more difficult to synthesize and enter the target crystal. Therefore, the energy selection of the added crystal is a very delicate problem. This is a life-and-death issue, because the crystal stone is a matter of life and death.

If the synthesis fails, it is not the consequence of the energy dissipation and loss of two crystals. Once it fails, an explosion will inevitably occur. The power is very powerful. If the crystal exceeds 20,000 terres, the golden-level mage will die. If more than 40,000 terres, even the legendary mage will die. The only synthesiser of the 60,000 terres in history, the legendary mage Tanya was killed when further synthesis. Before she was blown to death, she once said that the time she synthesized to 60,000 terres was completely based on luck."

"What about the demigod?" The fast-witted student heard the loophole in Vivian's words: "Since you, teacher, such an explosion demigod can withstand it, why didn't the demigod synthesize the second 60,000 terite crystal?"

"Ha, more than 70 years ago, a human demigod was addicted to crystal synthesis and challenged the synthesis of 60,000 terite crystals four times, but they all failed in the last step." Vivian shook his head and sighed.

"What happened later?"

"It's bankrupt, with a debt of more than 40 million gold coins. In order to pay off the debt, I could only go around to explore and finally died in the depths of the death jungle." Vivian shrugged and said as if nothing had happened: "So, even if you have a hard life in the crystal synthesis, it would be useless if you don't have enough money."

"The topic is far away, so continue to talk about how much capacity to choose to add crystals." Vivian said: "Based on thousands of years of experience, people generally choose five thousand terite crystals as added crystals."

"Hey, hey." Panis, who was originally straight, was already drowsy on the table. He heard someone talking to him in his ears: "Your name is Panis?"

Panis opened his eyes reluctantly, looked at a male student sitting in the seat next to him, and nodded: "Yes, what's the problem?"

"You also live with Teacher Vivian and the pastoral sister?" the male student asked excitedly: "I heard that they all live together."

"Well, that's right." Panis nodded.

The male student showed a leisurely expression on his face: "I really envy you."

"Oh?" Panis became interested and blinked at the male student in a narrow voice: "It seems that you are very abnormal to yearn for that pastor sister, hehe."

"Why is it abnormal?" the male student retorted with a flushed face: "It is abnormal for such a beautiful girl, a gentle and weak priest, and such beautiful silver hair. It is abnormal for such a girl to not be longed for by others."

"Gentle and weak, haha." Panis glanced at the male student with a slanted eyes: "If you are like this, she can kill twenty of them with one blow, so how can she be gentle and weak?"

"It's really true? Are you really living with them?" Hearing the conversation between the two people, a female student with hair erected on the other side, a huge silver ring on her ears and a thick black eye shadow could not sit still, and came over and whispered: "Then do you know that knight sister too?"

"Are you?" Panis grinned: "You're a girl."

"What's wrong with girls? Don't discriminate against women, okay?" the female student said with her eyes widened: "The pursuit of beauty is not different from men and women, especially the handsome and beautiful complex like the Knight Sister, which is really unforgettable."

"Okay, okay, you won." Panis said, rubbing his arm, "I don't discriminate, I'm just a little cold."

"That." The male student reached out and poked Panis: "Can you tell me the name of the pastor sister?"

"Yes, yes." The female student licked her lips: "And also the name of the Knight Sister, let me know, it's better to have personality and hobbies."

"You..." Panis frowned and said, "You actually want these?"

"Don't be so serious." The female student gave Panis a charming look: "We can make a deal."

"Trade." Panis suddenly reached out and pointed at the female students in the classroom: "Did you see this, this, this, this, and that, those beauties, give me their names, age, address, and preferences, and I will tell you. If there is more detailed content, hehehehehe, I still have a blank memory crystal there, you know, hehehehehehe."

"Hehehehe." The three of them leaned their heads together and made a wretched laugh at the same time.

"Huh." A huge wind sounded. As soon as the three of them looked up, a huge fireball hit him, accompanied by Vivian's angrily shouting: "Pennis, get out of here."

Panis chuckled, and the next moment he had already walked out of the window. The voice came from outside the window as his body fell: "I'll wait for you to get off get out of class at the entrance of the building."

The only remaining students were a man and a woman who were hit by a special fireball. Although they were not injured, they were covered in gray and black.

"You two." Vivian pointed to the two unlucky victims and said angrily: "Your class results this year are deducted 10."
