"What's your name?" Garlic asked him with a smile.

"Teacher, my name is Luo Yutian."

"Luo Yu, oh my God." Garlic whispered Luo Yutian's name a few times, and then laughed: "Good name."

"Hehe......" Luo Yutian just smiled.

Garlic said: "Don't look at the classroom is relatively simple, I am the class guide of the first class of the condenser." Since there have been no students in the classroom for several years, this has become my research room. At that time, I didn't have time to clean up when I received the teaching notice, don't dislike it! ”

Luo Yutian was more concerned about what Garlic Bi said, 'No students have come to class for several years', no wonder the surroundings were so quiet when Luo Yutian passed by the classroom just now!

Garlic Bi brought two chairs in the past, one for himself to sit on, and the other for Luo Yutian to sit on.

"Sit down." Garlic sat down.

"Thank you, teacher." Luo Yutian naturally didn't shirk it.

"First of all, the first question, how much do you know about the profession of Condenser?" As soon as Garlic mentioned the topic of condensers and the like, his expression would become very serious, not like his usual smile. In this regard, Luo Yutian can see it.

Luo Yutian naturally didn't dare to hide it, "Teacher, to be honest, I don't have much experience as a condenser. I don't know a lot of metals yet, but there are some energy metals that I still know. There are also some spirit alloys. ”

"Yes. It's normal for you to be too young to understand. Nowadays, almost all people spend their time on cultivation, so relatively speaking, there are relatively few condensation masters. In the five major courtyards, except for one or two teachers who teach condensation in the four outer courtyards, I am afraid that only the condensation masters in the core inner courtyard are relatively strong. Now there are fewer and fewer condensers in the world of all spirits, and there are even fewer within the nine ranks. Therefore, the fighting armor required by the current supernatural cannot complete the psychic level at all. Garlic said lightly, "Okay, you just said that you know some spirit alloys and energy metals, so I'll test you a little." If you really can't, that's okay. ”

Luo Yutian bowed slightly.

"Molybdenum." Garlic spat out two words.

Luo Yutian said: "The color of molybdenum is milky white, and it is also a kind of energy metal. Because it is milky white in itself, there will be very few magazines in the body, and it will not easily fail when used for condensation. ”

After Luo Yutian finished speaking, he looked at the garlic in front of him.

"You're half right. As condensers, the moment we get the metal, we should first feel the energy fluctuations in its body and the tendency of the elements. Although the failure rate of molybdenum is relatively small when it is used for condensation. However, if it is a defective product of molybdenum, it is impossible to judge the quality of the metal if you cannot feel the energy breath contained in its body. For example, the sixth-grade spirit metal is difficult to use to condense the Dou Armor. Garlic got up and went to his research desk and pointed to the drawings on the table.

Luo Yutian also got up and went over.

All he saw was a table full of drawings and metal. But comparatively speaking, there are more drawings.

"Metal blueprints?" Luo Yutian's eyes showed a different color.

Garlic bowed slightly, "Yes." Generally speaking, the condensation of the fifth grade of spiritual metal begins. We all need to study the metal, and the chance of re-refining failure of the spirit alloy is as high as more than 90%. So, we need to dig deeper into them. Knowing their internal structure allows us to be more prepared to introduce energy for refining during the condensation process. ”

"Teacher, the role of drawings is more than that, right?" Luo Yutian glanced at the garlic.

Garlic said with a smile: "That's right. In addition to providing an in-depth record of the metal, drawings can also be used to design Horcrux slayers in general. ”

"Horcrux slayer?" Luo Yutian shook slightly.

Garlic nodded, "That's right, it's a Horcrux Slayer." However, it's not very good for you to touch a Horcrux slayer at your current age, and besides, I'm just a fourth-grade psychic condenser. It takes a lot of time to design a drawing, let alone condense the metal. ”

Luo Yutian was thoughtful.

"Have you ever refined metal? Or has it been condensed? Garlic asked him.

"Teacher, is there any difference between condensation and refining?" Luo Yutian asked him rhetorically.

"Condensation is to shape metals, while refining is to change the shape and origin energy of objects and metals."

"Do metals also have origin energy?" Luo Yutian was slightly surprised.

Garlic smiled, "Why not?" When metal has spirituality, it will contain the original energy. However, the Origin Energy they contain is weak in our eyes. But if it's used to condense into fighting armor and Horcrux destroyers, it's the icing on the cake. ”

Luo Yutian said lightly: "If that's the case, then I should have tried both."

"So, you can choose a way to show me." Garlic Road.

Luo Yutian thought about it for a while, and then said, "Then, I'll choose refining."

"I see." Then, Garlic Pi picked out a few pieces of inferior metal on the table, and made a vacant seat in front of Luo Yutian's eyes.

"The first piece of metal counted from the left is a defective grade technetium. The second piece is a normal grade of dark silver, while the third piece is an intermediate grade of red essence and aluminum essence. So, please tell me your options. Garlic set his eyes on Luo Yutian.

One is a defective grade, one is an ordinary grade, and two are intermediate grades.

Comparatively speaking, the higher the grade of metal, the easier it is to refine. Comparatively speaking, the chance of failure is only half. Darksilver itself is a kind of energy metal, but it is now a defective metal, but it has greatly increased the energy fluctuations of the darksilver itself that is polluted. The last time he was in the library, Zhiyuan also asked Luo Yutian to refine a piece of defective metal. It's just that I've suffered a loss once, and it's better than the ordinary grade of Shen Technetium. It's not as difficult as defective metals, and for Luo Yutian, he should choose an ordinary grade of Technetium Essence.

"I choose a normal-grade Xuanyin." Luo Yutian said lightly.

"Oh." Garlic seemed to be surprised by Luo Yutian's choice, "Can you tell me why you chose an ordinary grade Xuanyin?" ”

Luo Yutian replied: "I think." If I choose the defective metal technetium essence, with my current cultivation and refining ability, I will not be able to control the powerful pollution energy in the body of the defective metal. After all, defective metals are also known as 'metal undead', and if the polluting energy in the metal is not well controlled, it will cause energy backlash and energy depletion instantly. Therefore, with my current fourth-order primordial ability, I still can't control the polluting energy in the metal very well. And the mid-level metals are almost all full of powerful elemental power, and the highest elemental power released is at least the strength of the second order or higher of the ordinary ability. Although the success rate of the mid-grade metal is very high, it is, in my opinion, the success rate is too high. Therefore, it may eventually destroy the original energy of the metal itself. For me, the ordinary grade Xuanyin is undoubtedly the best. ”

"You've made a good choice." Garlic laughed.

Then, Garlic pointed to the three-dimensional condensing furnace on the left, "This is the one used in the condensing furnace, is it okay?" ”

"No problem." Luo Yutian naturally didn't dare to dislike it.

Luo Yutian picked up the Xuanyin on the table and walked to the condensation furnace on foot.

Luo Yutian put Xuanyin into the condensing furnace. The furnace was a little dark, and there was a lot of dust piling up inside and outside. As soon as Luo Yutian put Xuanyin in, the dust inside spewed out.

"Giggle...... After Luo Yutian inhaled the dust, he naturally reacted immediately.

After the dust in front of Luo Yutian cleared, Luo Yutian turned around and looked at Garlic Bi with a speechless expression.

Garlic smirked, "Hehe...... Excuse me! It's been a long time since it's been cleaned. ”

Luo Yutian was helpless for a while!
