If it is said that before the "love make-up class" began, Tian Yang doubted Chen Mengmeng's ability. It was only two days before he began to doubt himself.

"Chen Mengmeng, you confess honestly, are you hiding clumsy?" Tian Yang glanced around, and sneakily leaned into Chen Mengmeng's ear and whispered.

"What's hidden?" Chen Mengmeng, who had just finished reading "Introduction to Mecha Design (Volume II)", raised his head from the pile of books.

"No, you've only been reading two days, and you've read all the two primers! It's still backwards! Tian Yang looked at her suspiciously, "Anyway, we have studied these two books for a semester as an elective!" ”

"But it's really easy to remember." Chen Mengmeng unconsciously continued to stab Tian Yang.

She wasn't lying, compared to the awkward and esoteric things that the old man told her to memorize, this beginner's primer was too clear and easy to understand, and she could quickly understand and memorize it.

"Ahh Tian Yang covered his chest with an exaggerated expression, and fell weakly on the table and lamented, "Is this the world of Xueba?" ”

"Cheer up," Ivy gave Tian Yang a slap mercilessly, "This is just getting started." ”

"Yes." Tian Yang jumped up again, and grabbed a thick copy of "Mecha Design Elementary Volume" that he used in high school. "It's time to show my true skills! Mengmeng, you take it! ”

However, four days later, in the empty classroom.

"What about Tian Yang?" Chen Mengmeng looked behind Ai Wei and Tian Xin, and the figure that usually jumped up and down did not appear as usual.

Tian Xin smiled awkwardly: "Tian Yang said that he was not very comfortable today, so he couldn't come." ”

Ivy rolled her eyes: "Actually, he complained to us today that you have already eaten the elementary level in just four days, and as a person who has only taken electives for two academic years, he is no longer qualified to teach you, and then claimed that he has suffered a huge psychological blow from you, and he wants to go to the school psychological counseling room to see a doctor." ”

？？？

As for it???

"To be reasonable, I was forced to take mecha design at home, and I think I had a big head to read that elementary book. Why do you understand it at a glance? Tian Yang said that he didn't have a chance to make a move. Basically, you flip through the book, and the rest of the time you ask a question or two, and he doesn't necessarily ask them. Ivy grumbled, but unequivocally took out a small box from behind her.

"What is this?" Chen Mengmeng looked curiously, the dark green box was wrapped in a layer of elegant velvet, inlaid with silver thin lines, and it looked very golden.

"I'm going to be your teacher today." Ivy smiled, opened the box, and took out a small ink-colored bead. "This is a miniature wormhole storage bead, which is a little mecha made material that I found at home, and I'm here to open your eyes today."

Then, Chen Mengmeng watched dizzily as Ivy kept taking out all kinds of strange materials from the black hole projected above the beads, and even the foot hook of a monster!

Yes... This.. What kind of family is it?

Tian Xin, who was watching from the side, was still smiling, but when Ivy kept taking out things, a look of shock appeared on his face.

"With titanium alloys, Isher stones, high-solid energy crystals, radium iron... Red Crystal Worm Hook? ”

In the end, Tian Xin, who had always spoken softly and gently, changed his voice.

"Tian Xin?" Chen Mengmeng looked at the reaction of the person next to her, and poked her secretly, "Aren't these very expensive?" ”

Tian Xin swallowed his saliva silently and nodded.

"At least you can buy a small city."

This time, Chen Mengmeng tried to close her mouth, she felt that she should call Tian Yang over to take a look, maybe he would know that Xueba is nothing great, and the father of the gold lord is the eternal god.

"This is the most commonly used in the book, and it is also the most basic titanium alloy in the battle mecha material, which looks like this."

"It's the Stone of Isher, which automatically stores solar energy and converts it into kinetic and thermal energy."

Chen Mengmeng was like a curious baby, asking Ai Wei and Tian Xin one by one.

It turns out that the pentapeptide liquid gold looks like this,

It turns out that this is the magnetic pole iron wood mentioned in the book

So in the glittering room, Chen Mengmeng saw the door of the new century.

Ivy was a little happy to see Chen Mengmeng sincerely asking for advice from her. If there was a little tail behind her at this moment, it must have been cocked. After all, she also wants to contribute as a sister group, but she knows seven out of eight for mecha design—none of them. Every day, I watched Chen Mengmeng bury herself in hard reading, and asked Tian Yang and Tian Xin if she had questions, which made her, the self-styled "eldest sister", very nonexistent.

What Ivy didn't know was that many of the materials she brought with her were of the highest grade on the market, completely beyond the scope of elementary textbooks. Although Chen Mengmeng has never seen any of them, she is very familiar with their names, and they are all mentioned in the notes given by Seth.

Chen Mengmeng only needs to match the name of the material with the appearance to be completely familiar.

Ivy raised the dark red foot hook in her hand with a little pride, "This was hit by my grandfather when he went to the battlefield before, when that red crystal Zerg was already fully mature, quite powerful, and directly attacked a detachment of our Gallo Empire Mecha Second Brigade, and later my grandfather took several squads to destroy it." I've heard of this foot hook which has excellent ductility and is a good forging material for. What's suitable? ”

Ivy scratched her head, she was really not interested in mech design.

"It is suitable for building a telescopic rope behind the mecha, the best quality is cut within one hour after the death of the red crystal worm, and the best effect is 5 times before and after melting it at high heat for 2 hours and then putting it in ice water." Chen Mengmeng opened her mouth to answer without thinking.

“？？？”

What is the incomparable familiarity in this speech?

Ivy trembled and pointed to the pile of things in front of her that she had just introduced with great interest, "Mengmeng... Is this really the first time you've seen these materials today? ”

"Yes," Chen Mengmeng nodded sincerely.

Ai Wei stared at Chen Mengmeng expressionlessly, and spit out a sentence half-loudly:

"You're not playing us, are you?"

.......

"I swear by the results of my mecha competition." Feeling the faint murderous aura in Aiwei's words, Chen Mengmeng quickly raised her right hand obediently and swore an oath.

"And how do you know that?" Ivy raised the dark red in her hand.

"I can see what I saw in a book in the library"

The murderous spirit is gone, and today is also a harmonious sister.
