"Ladies and gentlemen, this is the low-earth orbiter 'Feiyun', with a transverse diameter of 3,100 meters, a longitudinal radius of 680 meters, a maximum crew of 12,000 people, and a long-term self-sustaining capability, which can fly in low-earth orbit and near space, with a maximum flight speed of 2 million kilometers per hour, and a continuous full-speed flight time of 15 minutes in the atmosphere."

Du Yuheng, as the representative of Xuanmen, took the most powerful group of people in the whole green star to visit the Feiyun, and these guys, who are usually high, listened to Du Yuheng's introduction carefully like primary school students.

The proud Du Yuheng took everyone from the outside to the inside to carefully touch the flying machine, these old guys who don't know how many years they have lived are also emotional, this thing, a 100,000-year-old antique, the meaning and story contained in it, it is indeed embarrassing.

When they arrived at the central control room, everyone looked at the omnidirectional passive detection magic array that was still running, and asked questions again, until they asked all the questions they could think of.

"The child is Du Yuheng, right?"

"Yes, Xuanmen Du Yuheng. ”

"That Du Yuheng from the Tang Kingdom Advanced Magic Academy?"

"Do you know me?" Du Yuheng looked at the short-haired old man with a lovely smile in front of him, and his eyes lit up.

I am Tong Yunhu, an elder of Xiaoyaomen, and the heavy weapons of the military are all designed by us, so we can be regarded as peers. ”

Tong Yunhu's words did not have the feeling of being condescending or relying on the old to sell the old, but communicated with Du Yuheng with a peer and equal attitude, and won Du Yuheng's favor at once.

"It turns out that you are Chairman Tong. I've always admired you. I put your self-cooling large-caliber magic cannon on the table as a mascot. That's the pinnacle of things! It's also the goal of our younger generation!"

"Hehe, you're too polite, you're a rising star, and we're all out of breath!"

"Ha, you're so polite. ”

Tong Yunhu smiled so hard that his eyes narrowed into a slit, and said in a very serious tone: "I'm not polite, we can't get a sample of the rapid-fire cannon you asked for for the automatic defense system designed by the military!"

"Hehe, that one is purely a little embarrassing, in fact, it is really difficult at the current level. ”

"You can't say that. That Wyvern of yours doesn't use this rapid-fire cannon, it's almost impossible to defend against. ”

As soon as the two technical masters talked about the things they were interested in, they couldn't stop, and the familiarity of the two suddenly rose in a straight line, and they almost hooked their shoulders to call their brothers, and they discussed the rapid-fire cannon for a while, and the topic returned to the Feiyun intentionally or unintentionally.

"I heard that your Xuanmen is going to repair and improve the Feiyun after the imitation work is completed?"

"Well, Senior Brother has this plan, but it's just a plan, all of this will not start until the imitation is over, and the first thing is to repair it. ”

"So. How can we repair it without damaging the structure of the aircraft, especially the structure of the magic array? Then you might as well rebuild a flying machine!"

"Well, there is indeed this concern, now Senior Brother and I are also thinking of a way, Senior Brother proposed a concept of self-refining magic array, speaking of which, this is still inspired by the self-cooling theory you designed, Senior Brother hopes to complete the long-term alchemy effect through an alchemy magic array circuit set in the magic array circuit, and constantly and slowly improve the metal structure to eliminate the fatigue of the metal structure. ”

Tong Yunhu's eyes lit up, this idea is quite interesting, if it can be realized, it is indeed a revolution in manufacturing technology, this Xuanmen seems to be very good at innovation, and once it succeeds, it is something that changes the world world, it is really unreasonable for such a sect not to enter the chairman meeting of the Demon Research Association!

"It's a good idea, but it's not easy to implement, I'm looking forward to it, if it succeeds, but it must be taken out to do a technical exchange, we're the first in line, hehe." ”

"Definitely, we can exchange bilaterally first!"

"Ha Lu, yes, a word is a certainty!"

The two of them didn't care whether this technique was still just a plan, but they began to discuss the matter of exchanging techniques, as well as the application prospects of this technique, and they were excited, and they didn't care about all kinds of eavesdropping and sideways glances around, this was really like no one else.

"This Feiyun will be repaired in the future, what is the Xuanmen going to be used for?"

"This is naturally used as a flying machine for personal use or commercial use, the Xuanmen family has a small business, but there is not so much money to make a new one by yourself, you build a new one, we have to use the old refurbiment, speaking of the value of these alchemy materials is really a bit painful!"

"Hehe, isn't it, such a big guy, I don't know where our ancestors got so many valuable materials. ”

"Where else can it be dug from the ground, no wonder it's difficult to find mineral deposits now, hehe. ”

Du Yuheng glanced at the guy who interjected, he didn't know, but Du Yuheng didn't care who he was, and he had to refute if his point was wrong: "Who said, our ancestors used metals very efficiently, almost all of them were recycled, and the matrix of these metals would not be expensive, but the use of more advanced alchemy techniques and formulas, as well as a large number of precious animal and plant medicines, greatly improved the characteristics of these metals." ”

"I see, so do you have the recipes and refining techniques for these metals?"

Du Yuheng suddenly, it turned out that this was fishing, can he be so sneaky, Du Yuheng squinted his eyes dissatisfiedly and said: "This thing will appear in the research materials of the Demon Research Society, and it is not a secret, you don't have to talk to me!"

"Ugh"

"Halu Hagadru, be ashamed, you Zoroastrians are sneaky, you were also the ones who caused trouble in the Niya Forest last time, haven't you lost enough people!"

"Hmph, I'm just asking, and besides, we are the Demon Fire Cult, so don't use the insulting word Zoroastrianism. ”

"Hehe, everyone is not stupid, the Demon Fire Sect, which is good at metal alchemy, still doesn't understand the problem of metal utilization efficiency, okay, don't speculate for more than half a sentence, Yu Heng, let's talk in another place." ”

Du Yuheng smiled and nodded, "Okay, by the way, Chairman Gardrew, my senior brother asked me to ask about Joseph's officiating priest." ”

"He's very good, and he's practicing very hard, in order to get something back in return, thank you Xuanmen for your concern!"

"That's good, my brother said, you are welcome to come and find fault at any time! But remember to bring cash, there will be a fee when the time comes, haluha. ”

After Du Yuheng finished speaking, he really pulled Tong Yunhu out of the house, and everyone was a little funny, the contradiction between the Xuanmen and the Demon Fire Sect seemed to have really fallen to the root, of course, no matter which sect it was, they were actually happy to see this result, but they all had some ideas about the fact that the Xiaoyao Gate was so close to the Xuanmen.

At this chairman's meeting of the Demon Research Council, when the Eastern Continent Branch proposed to add Xuanmen to enter the chairman's meeting, the Western Continent and the Southern Continent both voted against it, and the Northern Continent abstained this time, but Xiaoyaomen was clearly in favor, and it is estimated that this motion will be put forward again at the next meeting, and Xuanmen should be able to enter the chairman's meeting without surprise, and the power structure of the Demon Research Council will change.

This thing seems to be unstoppable, and now I still want to think about how to face this change, in fact, from the current understanding of Xuanmen, Xuanmen's aggressiveness is not strong, some like the same mountain gate, I believe that there is one more Xuanmen, and the Demon Research Association will only have one more stable force, not a guy who makes wind and rain.

What's more, the series of revolutionary changes that Xuanmen has brought to the Demon Research Society are of great benefit to everyone, and from this point of view, absorbing Xuanmen is definitely a very cost-effective thing.

Let everyone explore around on the Feiyun, Du Yuheng and Tong Yunhu went to the top platform, Du Yuheng introduced to Tong Yunhu how Xuanmen got this thing, of course, it is a modified story.

"So, there must be quite a few of these flying machines above our heads, so why don't they land?

"Because of fear, or whatever, you think, they haven't returned to the ground for tens of thousands of years, why are they coming back now? Moreover, when something goes wrong with the aircraft, it may not always be possible to accurately predict it, just like this Feiyun, at that time they were full of confidence that it could support three or four years, but after we took over, several sects repeatedly evaluated, in fact, the aircraft will not disintegrate in more than six months at most, so the danger is likely to come silently, and they don't even have a chance to choose. ”

"Is it possible that one of them will sneak back to the surface?"

"There must be, Chairman Xiang once suspected that our Xuanmen also came here like this, hehe. ”

"It's a real deal!"

"Hehe, if those guys in the sky think the same way, let's try to get them all down, at least the materials of these flying machines will be worth a lot of money, right!"

"By the way, why haven't I seen your senior brother, I'm also curious about him!"

"He, he doesn't like this kind of occasion, he says it's a waste of time, so he sent me, he went to ask Tianzong's library by himself, he will appear at the banquet in the evening, it should. ”

"Hehe, good habits, very good appetite for me, by the way, are you interested in going to Xiaoyaomen to play? We have a lot of beauties in Xiaoyaomen, do you want me to introduce you to one, we don't have so many rules in Xiaoyaomen, and it's okay to marry other sects." ”

"This can be considered, but the senior brother will be exempted, his child daughter-in-law is very jealous, hehe!" (To be continued......)
