Cen Xiyan and the other five people opened the large package on their backs, each took out a bunch of parts from it, and began to assemble it.

Wei San and the others stared, but they couldn't understand what they were doing at all, let alone what the pile of things they were carrying was.

There is a big question mark in their minds, and they can't understand it when they see it, and they can't think about it clearly.

Once, Wei San always thought that he was a person with rich experience, profound knowledge, and a wide range of knowledge, but this journey with Suifeng and others, what he saw and heard, made him have to sigh, sure enough, there is a sky outside the sky, and there are people outside the world!

In this world, in some fields and levels that he usually can't touch, there are some things that he really can't compare to some people who work the rivers and lakes.

But even so, he didn't think that there was really anything in this world that others could see and recognize, but he had completely seen and heard of it.

But at this moment, in the face of these strange things in front of him, the pride and confidence in his heart were almost knocked to the dust!

He tried to think about it for a long time, and went through all the essays and ambitions he had read and thought of in his mind, and he didn't have any impression of the things in front of him.

Cen Xiyan, Cangqing, Canghai and other five people, when assembling parts, their expressions were almost the same, their lips were pursed, their eyes were focused, and they were extremely serious and dedicated!

Their hands moved skillfully and quickly, and there was hardly any sound except for the slight grinding sound between parts during assembly.

Wei San, Chen Liu, Zhao Er and the other five people stared at several pairs of eyes and looked at them for a long time, and finally Wei San finally found his voice and asked dryly, "Need ...... How can we help? ”

"No, you don't! Rest in place, talk less, don't make a sound! Cen Xiyan spoke dryly, his expression was serious, and he glanced at Wei San, and that look seemed to blame him for suddenly opening his mouth and disturbing them to do things.

Wei San shut up in amusement and watched silently from the sidelines, barely blinking his eyes, for fear of missing something important that surprised him.

About half an hour later, the sets of parts of Cen Xiyan and the others were finally assembled.

Wei San and the others looked at the five strange things standing on the snow, and in addition to being dumbfounded, they were still dumbfounded!

The five things, the overall shape is triangular, about three zhang wide, two zhang long, almost one and a half people high, the triangle above is made of canvas, blown by the wind, whirring, but it can be seen that it is extremely strong, supporting the triangular cloth surface, is some strange skeleton, I can't see what the name is, and under the triangular cloth surface, there is a hanging bag with two mouths side by side, there is probably one person to grow, and I don't know what it is for, in short, this is five strange looking big guys.

If you really want to say that these five things are like something, Wei San frowned and thought about it, it seemed to be a bit like a kind of swallow fish that he had seen in the South China Sea region!

"With the wind, this ...... What is this? Of course, Wei San is not the only one who has questions, and this time it was Chen Liu who couldn't help but ask first.

"It's called a delta wing, but they like to call it a 'bird's wing'." Cen Xiyan replied.

In fact, the more accurate name should be "unpowered delta wing aircraft", but the words "non-powered" and "aircraft" are too jerky and difficult to understand for the ancients, and she can't explain it to them, so Cen Xiyan has only referred to it as "delta wing" since she made this kind of non-powered delta wing aircraft, of course, she also thinks that Canghai They called its "bird wing" is also quite appropriate.

There are unpowered delta wings, of course, there are also power delta wings, but in this backward ancient times, the engine is a big problem that cannot be solved, so it is impossible to make a power delta wing, for this, Cen Xiyan regretted it for a while.

"Birdwings? Can this thing still fly? Zhao Er stared at the five delta wings with good eyes, and asked in a loud voice.

"Hehe, Second Brother Zhao, this time you guessed, let's fly over this snowy mountain!"

The delta wing was assembled, and Canghai also put away his previous serious and engaged expression, and returned to his usual smiling appearance.

"Fly! Fly over??!! When Zhao Er heard this, his eyes almost didn't fall off, "What are you kidding!" ”

He just heard the name "Bird Wings" and said casually, this thing can really take people fly? He couldn't believe it! I've never heard of anyone who can fly into the sky like a bird, and that's unbelievable!

If there is really such a big bird in the world, it can take people to fly, maybe it is a little bit reliable, but this strange thing in ancient times, it is not a real bird at all!

Not only did Zhao Er not believe it, but even Wei San, Chen Liu and others also felt that it was a pipe dream to rely on this strange thing to fly over this continuous snow-capped mountain group!

However, when Wei San looked at Cen Xiyan and saw the calm, confident, calm and calm expression on her face, a trace of hope suddenly arose in his heart that even he felt surprised......

"Are you kidding, you'll find out in a moment." Canghai smiled, and his tone was quite confident.

"Alright, pack up, we're ready to go!" Cen Xiyan beckoned everyone and arranged: "I will take the third prince of Wei to take a bird wing, Senior Brother Cangqing, you take Chen Liugongzi, Senior Brother Canghai, you take the second son of Zhao, chisel and hammer, you are responsible for taking Li Yan and Wang Shu." ”

Li Yan and Wang Shu are the two guards brought by Wei San.

"Okay, I'm sure I'll get the job done." Canghai replied with a smile.

"Yes, Childe!" Chisels, hammers, loud voices, agreed in unison.

Cangqing, the stuffy gourd, was as silent as ever, but nodded at Cen Xiyan with a serious expression.

Cen Xiyan took out the special helmets they brought and distributed them to Wei San and the others one by one.

"Helmets too?"

Wei San knocked on the helmet in his hand, the weight is not light, and it is so hard, it is made of thin iron? It's very different from the armor helmet worn on the battlefield, this helmet is covered tightly by the entire facial part, only a few holes are left such as the nose, eyes, and mouth, and the two holes in the eye area are also pasted with two transparent things, Wei San took a closer look and found that it was a glass piece! Such a luxury!

If this kind of helmet is used on the battlefield, it can better protect the head safety of the soldiers, but it is ...... The cost is too high!

"Of course you have to wear it! The sky is windy and dangerous, so wearing a helmet is the only way to protect your head from any damage. ”

As for what dangers there are, Cen Xiyan doesn't want to give examples one by one at the moment, because there are some examples that they can't understand, for example, in the 21st century, in the sky, a bird can crash a plane!
