Even an academy is in crisis, how will it compete in the world in the future. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Info didn't dare to waste any time, Fang Ruitao sat on the bed and meditated and cultivated for two hours, until the true qi and battle qi were full again, he lay on the bed and fell asleep. Since coming to this world, Fang Ruitao slept on a comfortable soft mattress for the first time, and he slept very sweetly this night, until the fat man Feiqi woke him up the next morning.

"Boss, Boss Fang is about to get up, if we don't leave, we'll be late. The fat man shouted loudly, and used his fingers as thick as radish to flick Fang Ruitao. Fang Ruitao narrowed his eyes, kicked the fat man into the corner of the wall, and muttered to himself: "It's disturbing people's dreams early in the morning, and the fat man is really annoying."

Fang Ruitao turned over, but then he realized something, and jumped up from the bed suddenly: "By the way, it seems that today is a good class." ”

The fat man who was holding his stomach with a painful expression gradually got up and said, "Yes, Boss Fang, I came to tell you to get up and go to class, you actually kicked me out so hard, it seems that your life is still in danger as a little brother." ”

"I'm sorry, I'm in a daze. Fang Ruitao said with some embarrassment: "Absolutely not next time." ”

The fat man said with a painful expression: "Is there a next time? There is no need to apologize, I haven't eaten breakfast yet, Boss Fang, do you want to invite me to the cafeteria to eat again." As for the steamed raccoon meat with five gold coins and a plate of five gold coins ordered by Miss Gu last time, I only need to eat ten plates and eight plates to be satisfied. ”

"Ah......" Before the fat man Feiqi's words were finished, he was kicked out again by Fang Ruitao.

After eating some breakfast in the cafeteria, Fang Ruitao and the fat man Fei Qi ran to the classroom in three steps and two steps. Fortunately, the fat man was quite familiar with the geography here, and they rushed straight to the classroom without looking for it, which saved them a lot of time.

Walking into the classroom, which was already full of new students, they found a seat near the corner and sat down, calming their hurried breath as quickly as possible. As soon as the two of them sat down, an old man with a white beard walked into the classroom with an ancient book thick enough to crush a person. He opened the book on the stand next to the podium, cleared his throat and said, "My name is Capri, and from now on I will be the main teacher of your primary magic refining foundation, and in the next month we will focus on learning the various basic knowledge of magic alchemy, and today we will start with the material of alchemy. ”

The old man ignored the chaotic students below, and began to talk at length about the selection of alchemy materials, as well as the smelting and forging conditions of various materials. Fang Ruitao glanced at the old man who was chattering, and felt bored for a while, these beginner courses just let the students understand the various materials that need to be used in the magic refining, to put it bluntly, it is almost the same as metallurgy. On the Celestial God Continent, there is very little selectivity in alchemy materials, and metal materials are generally used, and the primary alchemy knowledge is how to purify these materials.

The metallurgical level of the Heavenly God Continent is not very high, it is a few levels worse than the ability of Fang Ruitao's micro factory, and it is several grades worse than what he learned on the earth, that is, Fang Ruitao understands that bit of theoretical knowledge is definitely higher than them, so he doesn't need to learn this subject at all.

The old man had been talking about the selection and purification of magic alchemy materials all morning, and the boredom made Fang Ruitao feel drowsy all the time, and it was not until the bell rang at noon that Fang Ruitao woke up.

"Boss Fang, you don't seem to have been concentrating on the class, are you all right?" the fat man Fei Qi leaned over and asked strangely, although he usually looked very aggressive, he was still very serious in class.

Fang Ruitao sighed and said, "I already know everything this teacher said, and there are still many mistakes in it, what else do I listen to?"

"Do you hear something wrong?" Can you explain it to me?" a cold voice came from behind the two of them, startling them.

Fang Ruitao followed the prestige and found that it was Teacher Capri standing behind them, looking at them with indifferent eyes. During class, he found that Fang Ruitao had been drowsy, which made him feel very bad, so he wanted to come over and ask him a few words after class, but he didn't expect to hear his words before he could speak.

Hearing this, one of Capri's reactions was that the student was too arrogant, and he was bragging, so he couldn't help but ask out loud. If Fang Ruitao couldn't say why, he would have to scold the other party fiercely.

Seeing Teacher Capri's unkind eyes, Fang Ruitao knew that if he didn't come up with something, he would definitely be scolded very badly today, so he had to bite the bullet and say: "The teacher said in class that before using magic alchemy to depict the magic array, the selection and understanding of materials is particularly important, the purer the iron, the tougher it is, and the more it can exert the performance of the magic array, I can't agree with this point of view." ”

"Oh, the thousands of years of demon cultivators on the continent have all learned like this, and they have found through repeated experiments that the more the iron is forged to remove impurities, the better the iron quality will be, how can this be wrong?" Hearing that Fang Ruitao was not vexatious but seriously raised the question, Capri hoped that the other party would be able to express his unique opinion.

Fang Ruitao said: "There are indeed many impurities in iron, most of which also have an impact on the texture of iron, but this is not the main reason why iron is not hard enough, because some impurities are still good for the hardness of iron, in fact, what you need to remove is excess carbon." Fang Ruitao's words completely subverted the conventional way of thinking in the entire alchemy world, but it seemed to have some truth, so that Teacher Capri couldn't help but ask: "What does this carbon have to do with iron?"

Fang Ruitao said: "The iron ingot is very hard before refining, but the texture is very brittle, and it will gradually become tough during the forging process, the hardness has not changed much, but the toughness will be better, but if you continue to forge, there will be another situation, that is, the toughness of the iron is getting higher and higher, and the hardness is getting smaller and smaller." ”

These knowledge are all junior high school knowledge on the earth, and Fang Ruitao has naturally learned all of them, but at this moment, he told it eloquently, but it gave Capri an unfathomable and profound impression. "This change is because the carbon content in the iron has changed, the original iron ingot I called pig iron, this kind of iron that has not been forged contains too many impurities, and the carbon content is higher than two percent, so it will be very brittle, and calcined excess iron I call it wrought iron, it is because the carbon is removed in large quantities, because the carbon content is less than 5 parts per 10,000 resulting in insufficient hardness. The kind with the best hardness and toughness, I call it steel, its carbon content is generally between 5 and 2 percent per 10,000, and the hardness and toughness of the steel at this time have basically reached the optimal state. "On February 6th, the 17th district of Xianxia Road will be opened, and the game level will reach level 50 and 11200 grains will be automatically received
