"Ladies and gentlemen, I don't know how to operate the next process of how to increase the manufacturing speed of rails, so I will ask Xu Yiyi to explain it to you." Dai Huadong decisively ignored Xu Yiyi's words and pushed her up. At the same time, he whispered: "You should know about steelmaking and rolling, right?" Just ask them to tinker with this kind of equipment. ”

"Huh?!" Σ(っ°Д°; )っ

Dai Huadong decisively ignored Xu Yiyi's surprised expression with a hint of help, and began to applaud. Calling you almost made me unable to get off the stage.

The other students also began to applaud, and Xu Yiyi could only bite the bullet and start explaining to them, and then he became inexplicably excited, completely without that feeling of weakness, just like the kind of person who looks cold on the surface but looks like a neurotic when it comes to the field he is good at.

Although most of the students felt that Xu Yiyi was very different from last night, the knowledge she talked about was something more attractive to them, so no one questioned it.

However, the explanation encountered difficulties in the first place, and the ironmaking was questioned:

"Such a high temperature can't be achieved by relying on the existing forging furnace at all, and can only rely on high-level fire soul masters, so it is impossible to meet the requirements of high efficiency." It was a teacher who asked the question.

Xu Yiyi was stunned for a moment, and she asked, "Don't you have coke?" ”

The teacher looked puzzled: "Coke? What is it? ”

Dai Huadong remembers that he seems to have read in a chemistry book that coke is needed for steelmaking, and that this kind of coking coal can produce a higher temperature than ordinary coal after combustion, and it seems that there is a process of coking, but ...... Dai Huadong had almost forgotten about it, and the only thing that impressed him was the periodic table - because he had stupidly memorized the entire periodic table, only to learn that he didn't use so much in the exam......

"Coke is the carbon that can reach a higher temperature after coking coal has been processed...... Xu Yiyi began to explain to them what coking coal and coke are, and how to extract them.

Then those people suddenly realized, Dai Huadong also said, Nima I thought coke was what! It turns out to be carbon with a higher purity!

Then, in view of Dai Huadong's reminder, Xu Yiyi did not directly give the drawings of the steelmaking furnace and the equipment for dry distillation coke, but focused on the precautions in the design. Dai Huadong wants a group of scientists who can think for themselves, not a group of craftsmen who can only do what he says.

The noon break passed quickly, Dai Huadong clapped his hands, and said: "Our martial soul department still has classes in the afternoon, so we will teach here for the time being, and see you in this place in the evening, you can use this time in the middle to review, or try to develop the soul guide needed in the method Xu Yiyi said, after all, time can't be wasted, isn't it?" Goodbye, everyone. ”

Then Dai Huadong pulled Xu Yiyi, who was still unsatisfied, out of the classroom, Xu Yiyi finally got rid of that kind of teacher state, only then did she notice that her hand was pulled by Dai Huadong, and her face was suddenly flushed, and when she just wanted to remind her, Dai Huadong let go of her hand, and finally let her breathe a sigh of relief, although the island and Dai Huadong have a good relationship, but she is still not used to having physical contact with the opposite sex.

Huo Yuhao also followed, after all, he also had to go to class.

"Second brother, you are waiting for me," Huo Yuhao glanced at Xu Yiyi, whose red face had not completely receded, and showed a clear look, "I thought you were misleading us last time, but it turned out to be true, so I will leave first." ”

After speaking, Huo Yuhao ran away.

"......" Dai Huadong looked at Huo Yuhao's back as he ran away, and showed a smile, his white teeth looked so infiltrating.

When Xu Yiyi was said this, she suddenly remembered what happened in the cafeteria before, her face turned red again, and she said hesitantly: "That...... That one...... We ......"

"It's okay, the clear ones clean themselves, don't worry about this." Dai Huadong said that although the explanation is very important, there are some things that will only be more and more troublesome the more they explain, such as this one, the more they explain it, they will only think that they want to cover it up, so they simply don't explain, those guys will forget about this stubble sooner or later, and ......

"And, although now we are friends, but later...... How can you say that it won't be as they think? Dai Huadong looked at Xu Yiyi with smiling eyes.

A white steam suddenly came out of Xu Yiyi's head, and the red color instantly spread to the root of her ears, she covered her face, turned around and ran away.

Dai Huadong covered his nose, numb, and suddenly felt that this guy was so cute, and sure enough, it was because the image of the evil and cold queen of the outlying islands was too impressive - although it may be a little shorter (outlying islands: this is redundant. And then suddenly run away because of shyness or something...... Is it really a contrast?

In the afternoon, Xu Yiyi sat in the classroom, peeked at Dai Huadong and then quickly turned away, and the students next to her looked at her with a strange look and didn't know it.

"Outlying islands, do you think he ...... Is he serious? Xu Yiyi asked the outlying island in her heart.

At this time, the outlying islands are generally awake, and the deep sea does not need sleep, and she is not forced to sleep like Xu Yiyi.

[Don't pay attention to him, he's a guy with a bad personality himself, so he just wants to see other people's tangled expressions.] The outlying islands commented.

"Huh? Are you sure? Xu Yiyi suddenly blushed.

[This guy often dangles in front of me, of course I know his character. 】

"That is to say......"

[That's right, it's just that you're thinking about it alone.] 】

"Woo~" Xu Yiyi suddenly let out a sad cry and covered her face and lay on the table. Could it be that she herself has been thinking about it all the time?

[Also, this is my body, even if you have a crush on someone, I won't allow you to do strange things with my body.] 】

"Talent...... Not really! Xu Yiyi's face suddenly turned red.

“…… Are you okay? My face is redder than normal! "Dai Huadong doesn't think that even his hands are red because he is shy, he must be sick!

"I didn't ...... It's okay. Xu Yiyi hurriedly waved her hand.

“…… It's not normal to look at it, you're like a boiled crab right now. Dai Huadong reminded.

"It's really fine." Xu Yiyi forcibly suppressed her blood flow, and her face suddenly turned blue.

[Hey! Are you going to kill yourself? I'm not going to die yet! Stop it! The remote islands clearly feel the condition of their bodies.

"......" Dai Huadong looked at Xu Yiyi's face blue for a while and red for a while, how could he feel abnormal, but as a deep-sea ghost, how could he get sick? So what's going on? Is it the rejection of the world?

In an instant, Xu Yiyi's temperament changed, and the two soul rings were hidden under his feet and did not rise.

"Outlying islands?"

"That guy has a bit of a brain problem, don't worry about her, I'll teach her for the time being." Outlying Island glared at him.

"That...... You two are one body, right? Scolding each other like this......"

The outlying island reacted instantly, her face became extremely ugly, she stared at Dai Huadong with scarlet eyes, and said viciously: "Forget it for me immediately, otherwise I can only use physical methods to make you forget." ”

Dai Huadong immediately looked around: "What just happened?" Why didn't I hear anything? ”

The outlying island was very satisfied with Dai Huadong's reaction, nodded, and began to listen to the lecture in place of Xu Yiyi.

Dai Huadong doesn't know how strong the real ability of the outlying islands is, after all, it is difficult to compare different worlds, and he is not very familiar with the outlying islands - because he can't fight at all, so there is no need to understand - but he can be sure that the strength of the outlying islands should be stronger than Zhou Yi, she just turned on the martial soul in class, but Zhou Yi didn't find it at all, you must know that the outlying island is a land base, not a submarine that is good at stealth, even so people can't feel that she has turned on the martial spirit, it's just a monster.

"Anyway, you don't need to learn this at all, do you? Why come to Shrek Academy? Dai Huadong asked this question that had bothered him for a long time.
