"Hey, acquaintances hurry to the side, you dare to show me a look without asking, do you know Ji Haoyue, who was fifth in the last Hundred Birds Challenge, he is my brother!" As soon as Ji Haoyue's name came out, many eyes looked at it, and Ji Xiaoru became more and more proud. But the other party's appearance of not knowing what to do really made her angry, so she threatened: "I advise you not to provoke me!"

Ji Yan looked at the front lightly, his expression did not change from beginning to end, and when he heard the last sentence, he suddenly laughed and said: "Otherwise, this is the school, you or your brother, what can you do to me?"

Ji Xiaoru gritted her teeth and her eyes glowed with poisonous light, thinking that the other party was too arrogant, she thought that she was bound by school rules, so she didn't dare to do anything? Hmph, as long as it is done secretly so that the school can't find it, what do you say you can do?

Of course, there are some things that can't be said explicitly, so I have to give her a "wait and see" look.

In the refining class, the teacher adheres to the principle of applying what he has learned, adopts the practical teaching mode, and after introducing himself, he leads them to the refining room.

The interior of the refining room is wide and circular, and various materials are stacked on the cabinets against the wall, and in the middle of the house, dozens of smaller tripods stand around a large tripod, and the small tripod is not close or far from the big tripod.

The teacher asked each of them to choose a small tripod to stand on, and they stood next to the big tripod in the middle to start introducing the class. This teacher does not follow the rules at all, and does not use textbooks. All kinds of knowledge came casually, and students listened and watched at the same time, and the effect was remarkable.

"The first step in refining a tool is to select materials. For you beginners, it is enough to configure the materials according to the simple recipe. There is a book of materials in the school library, and students who are interested in going to higher places can borrow it, and the second step is smelting. A thousand alchemists will refine a thousand weapons, and the reason is the difference in heat. The size and duration of the fire will affect the quality of the weapon. There is no shortcut to mastering the heat, you can only rely on practice to perceive it, and the third step is watering. After the material is smelted, it needs to be poured into a certain container to form, and the speed of watering should be fast, otherwise the melting night will cool in the air, and the previous work will be wasted. ”

Ji Yan listened very seriously, although she had been learning to refine the instrument spirit for a long time, but in a sense, this was her first class! The material encyclopedia mentioned by the teacher was not attractive to her, she was already an encyclopedia of materials!

"Machine Spirit, what is the Instrument Formula?" Ji Yan asked with his mind.

"Some experienced veteran refiners will list the materials of the weapons they created for future generations, that is, the weapon side. But you don't have to bother with the device, you can just ask me if you want to know what recipe is!"

The machine spirit said proudly, thinking that the amount of his hundreds of years of accumulation is nothing more than the same in the world. What's more, not only do I know a lot, but I also create a lot, of course, I can't tell her!

The teacher felt that what he had said was almost enough, so he gave each of them a simple instrument to start practicing.

Ji Yan held the instrument in his hand, gearing up, can he finally touch Dading, think about it, and be a little excited!

Material selection, feeding, ignition, and control are finally watered, because most people are refining for the first time, and some are in a hurry, and the final results are quite miserable!

However, the result of the bony feeling did not affect Ji Yan's good mood, and while sighing that time had passed quickly, he was looking forward to the arrival of the next class. xh118
