"Master, how can you use swastika energy to divert the light path here?" Yun Yi couldn't hold back any longer, and opened his mouth to say. I only have one sentence for 151 Kanshu.com, the update speed is n times ahead of other stations, and there are few advertisements

These days, in order to cause unnecessary misunderstandings, Yun Yi has been observing more and talking less, carefully studying every step of Master Niu. At the beginning, Master Niu's profound knowledge and years of experience made Yun Yi breathtaking, and even gave birth to a feeling of worship. Compared with Master Niu, Francis of Weilong Group can only be reduced to a researcher who helps him.

However, with the deepening of the design work, Yunyi's doubts became more and more. At first, he was able to hold back, but as time went on, every day when he returned to the room, he began to think about those questions, and when he couldn't get answers, Yun Yi became a little irritable.

No, as soon as Master Niu made a design that diverted the light path, Yun Yi couldn't help but jump out.

"You know mecha design? There are too few young people who know some mecha engineering knowledge these days, and it's not easy. Master Niu didn't complain that Yun Yi interrupted his work, but looked at him with interest: "Tell me, why can't you use a swastika to divert it?" ”

"It's an extremely important point, if the driver is doing a high-frequency exercise, the energy that passes through here is very high, what material can withstand such pressure? I think it's better to use a double Z-shaped structure. Yun Yi pointed out this question unceremoniously, his eyes glaring at Master Niu, wanting to see how he answered.

Next to him, Li Xingke was discussing the loading and use of weapons with a researcher, when he heard Yun Yi's voice and hurriedly ran over, pulled him behind him, bowed his head and apologized to Master Niu: "Master, don't care, he doesn't understand anything......

"No, just because you don't understand doesn't mean he doesn't." Master Niu raised his hand to push Li Xingke aside, looked at Yun Yi and smiled: "I found out a few days ago that no matter what I am doing, you will observe carefully, and always show a deep contemplative look, I guessed that you should have a certain degree of attainment in mecha engineering, otherwise there would be no such actions." I thought you would be asking a question a few days ago, but I didn't expect you to be able to endure it until now. ”

Yun Yi was taken aback, on the one hand, because of the old man's observation, in addition to designing the mecha, he was also able to observe his every move. On the other hand, Yun Yi saw very clearly, the old man only used one hand to push Li Xingke "gently" to the side, if there is no innate cultivation or above, it is impossible to be pivotal.

Could it be that this old man is also a congenital?

So how old is he? No wonder Francis is not as good as him in technology, Francis's cultivation seems to be only six or seven levels, and his age is about a hundred years old. But this Niu Master is probably at least two hundred years old.

"As for the question you just mentioned." Master Niu pointed to a point on the light brain screen and said solemnly: "Although what you said is very reasonable, in my case, only the best mecha will be designed." Those things can also be called mechas? The old man pursed his lips, as if he was very disdainful, and continued: "Don't forget, there is a thing in the world called the Francium Crystal, and it is strong enough to withstand it. ”

"Francium Crystal!"

Yun Yi seemed to have heard this name somewhere, and he was still thinking about it and didn't speak. Li Xingke next to him shouted, causing Yun Yi to turn his head and ask, "What is the Francium Crystal?" ”

"A synthetic element that is bombarded with a thousandths femtosecond laser by extracting the isotopic decay of the core and francium of the stone and then through a series of complex high-pressure compounds...... The resulting product. ”

Master Niu's explanation made Yun Yi half ringing and did not come back to his senses, although he didn't know much about material science, but Yun Yi had heard that only asteroids in some remote galaxies had a very small amount of output, and the price of a pound of Zhu Yue Stone was almost worth more than 30 million, and its core was even more expensive. After such a complex series of processing and synthesis, the materials required to make a swastika optical path are probably worth hundreds of millions.

Yun Yi swallowed his saliva with difficulty, this is just a small part, and it needs such a high-grade material. Suddenly, the problems that I didn't figure out a few days ago are all understood, as long as you use more suitable materials, you can completely solve those problems, and the effect is much stronger.

But the price of those materials ......

Yun Yi finally understood why most of the mecha designed by Master Niu couldn't be built.

Where is this to build a mecha, which is simply using money in a pile of mechas. Even on the rich paradise island, I am afraid that few people can afford these materials, not to mention, even if they can afford them, I am afraid it will be difficult to find them. You know, some materials are so scarce that they are either controlled or left to chance. Just like the Stone, there are countless companies that mine in remote galaxies every year, but only the lucky ones can come across it.

If you want to get these materials, I'm afraid it's even harder than climbing to the sky. Even if the Chu and Tang Empires poured all their strength into the country, they couldn't build a few.

However, even so, it is not easy to know so many materials and be familiar with their properties and functions to apply them to personal mechs.

"Master......" Li Xing pleaded with a bitter face: "You can help me change the structure here, can you not use the francium crystal?" I escorted that thing last time, more than a hundred mechas, more than forty innate masters, and twenty state-of-the-art warships combined, just to escort three fist-sized flock-and-francium crystals. Do you think I'm going to use this thing? ”

Yun Yi was taken aback, he never thought that the price of the Francium Crystal would be so high.

"Don't change!" Master Niu waved his hand, with a look on his face that could not be refused: "I just need to design the best and most powerful mecha, as for the materials or anything, that's not something I need to worry about." ”

Hearing this, Li Xingke was stunned for a moment, glanced at Yun Yi, and the two looked at each other, it seems that this is the true face of Master Niu, no wonder there is the title of Niu Lao Crazy......

In the following time, Li Xingke no longer had the excited and expectant look he had in the past, and sat alone in a corner of the laboratory, bowing his head and being silent.

Yun Yi was not as frustrated as him, for him, after the design drawings came out, he could carefully revise them so that he could use ordinary materials. But there are not many opportunities to learn from Master Niu, not to mention, when you encounter something you don't understand, you can also learn a lot of material knowledge.

By six o'clock in the afternoon, everyone in the lab should be ready to go back.

In the hovering car, Li Xingke's expression was sluggish, and there was no trace of brilliance on his face. Yun Yi glanced at him and asked a little funny, "Can't figure it out?" ”

Li Xingke nodded, and said dejectedly: "When I was a child, the place where I lived was next door to Master Niu, I admired his attainments in mecha engineering very much, and I thought since I was a child that after I advanced to the innate level, I would let the master help me design the best personal mecha." But I didn't expect Master Niu to be like this...... It's no wonder that after those people finish designing with Master Niu, they will go to other designers. I used to think that they didn't look down on the master's design, but I didn't expect it to be the reason. ”

"Then why don't you go find another designer?"

Li Xingke sighed, but didn't say anything more.

Yun Yi patted him on the shoulder and said with a smile: "Okay, when the design comes out, you can see what materials you can find." As for the uneven place, hand over the drawings to me, and I'll help you revise them. ”

"You? Come on. Li Xingke smiled reluctantly, his eyes fell into the distance, not knowing what he was thinking.

Back at the place where he lived, Li Xingke was about to go back to his room, but was pulled by Yun Yi.

"One thing I have to tell you, Dr. Song's research is almost complete, and there is no longer a need for kites. When the mecha here is designed, I want to ...... Take the kites out of here......"
