Miria commanded several large trees and moved a large object. On the surface, this thing is similar to the airship I made, and it is a shell made of blue and white painted trees.

It's just that this shell is even larger, and the size is not as petite as its own airship, but it is similar to the previous airship transport, that is, the appearance of the first generation of airships. But if you look at this shape, there are some sharp points at the top and bottom, and the shape is similar to that of a fish, and there are things like fins around it.

If this thing is not used for decoration, it is used to control the direction. After Chi Nan inquired, he found that this thing was really used to control the direction. Without this thing, it's not very stable.

"It's also made of blue and white painted trees, and you can really use these plants on a large scale. It's just that this plant feels a little strange, and the fusion seems to be a little too stiff. Silinka stepped forward and said with a frown.

Chi Nan spread his hands: "After all, I didn't make it myself, I relied on the energy pool and permission to make it, and there were two procedures in between, so it's good to be able to do it like this." "Chi Nan can't help it.

Even if the computing power of the plant brain far exceeds his own, but I don't know why, as long as he doesn't control it himself, the fusion plant will definitely have flaws. The life magic of this energy pool always seems to be a little different from his own life magic. Chi Nan doesn't know what this is, maybe he can figure it out later.

"Don't care, look at our cover-up. The first is the powertrain, which is something we made. This power system absorbs the surrounding water and repells it, just like you can repel air. ”

After a test in Chinan, it was true that the absorption and repulsion of the water flow was very stable, which could provide a steady forward momentum. It's not as furious as the air, so it can't be that fast. In the water, the speed of this submarine is not comparable to that of an airship, but it is not bad. Even the position that absorbs the flow of water is also in the back.

It seems that this aspect can be modified, after all, it's just people in this world, and some of the horizons are not very broad. If the absorption of water is absorbed from the front, it can reduce the drag and speed up the speed.

Chi Nan took a look at the inside of the submarine, and sure enough, the structure of the floating ball was still used.

Using the float ball to directly control gravity, there is no need for such a thing as a drain tank to control the weight of the submarine. As long as gravity is used, it can ensure that the submarine can go up and down freely in the water, and even fly without any problems.

Of course, if it does fly, then this kind of submarine will not be able to move forward because of the thrusters. It can only float to the surface and is used to avoid some dangers in the water. This is something that submarines on Earth can't do.

"So, what about the weapon attack system?" Chi Nan felt a little interesting. I didn't expect them to be able to concoct a powerful and practical weapon, and the wisdom of multiple people combined should not be underestimated.

"Of course, our weapon is this, the Ice Cannon. Miria pulled out a spiky object.

Injected with magic power, this ice cannon quickly condensed the water element, and at the same time condensed the surrounding water flow, instantly condensing an ice pick at the tip. The speed of the ice pick shooting out in the water is not slow at all.

The ice pick pierced into the stone, and the next moment it exploded, and countless ice crystals scattered and condensed into ice needles at the same time, increasing the lethality. The stone that had been pierced by the hole had been shattered at this time due to the relationship between the cold and the ice needle. It's just that the stone retains its shattered shape and freezes before it completely spreads.

This ice power can be maximized in water. And there is a stream of water everywhere around, so you don't need to rely entirely on the water element to replace it, and it's also very magical.

"Yes, it's good, if it's connected to the Heart of the Sky, it should be stronger. ”

"Of course, this is not a wind cannon, the ice cannon can do a lot, the stronger the magic power, the more powerful the ice cannon will be, and the magic power is enough to launch quickly, and it is no problem to reach the silver level. ”

"Yes, very good, but what about gold-level weapons, can this be achieved? ”

"Theoretically, it is possible, but in practice it is too wasteful, not ideal, and needs to be strengthened. Olna opened her mouth, and Miria glared at her angrily, this good friend had come to dismantle her own stage.

Chi Nan nodded slightly, not feeling that there was any problem: "What about the problem of the defensive barrier, how is this solved." ”

Miria said angrily: "You can't do anything, and of course we don't have any." The defensive barrier we use is affixed to the surface of the submarine, as long as it defends most of the important positions. The positions of the weapons are vacated. ”

"Does that make the submarine vulnerable? Forget it, there is no such thing as an alchemy flying boat in the water anyway, and it doesn't matter if you are fragile. "In the sea, the main opponents are all kinds of magical beasts, and this Chi Nan knows it. That being the case, it doesn't need to be as invulnerable as an airship.

"That's what I thought, Olna said. Miria was overjoyed at once.

"The waterproof structure we have here is very good, and even if some of the shells are broken, they won't leak into the whole submarine. The central control room is in the middle and is absolutely secure. In addition, we have all the aquatic plants that maintain the air inside. ”

Chi Nan was really a little surprised at this time, it was incredible that these people could do this just through the energy pool authority. "Yes, that's good, your research skills are worth affirming. ”

Miria smiled, like a little fox who had stolen an egg.

"Is there only one weapon system, the Ice Cannon, and nothing else?"

Orna said expressionlessly: "No, there is only this one for the time being, is there something wrong, if not, don't form it first, otherwise it will not be good for Milia to die in the sea." ”

"Hey, what do you mean, what do you mean to die in the sea. You can command the airship, can't I? ”

Why did these two people quarrel, Chi Nan was a little big: "Okay, okay, I don't understand the things in the sea for the time being." In this case, first form a team and explore the sea, Miria should not control it on the submarine, but control it from a distance on the airship for the time being. Anyway, our signal transmission is very good. ”

"Signal transmission?" Slightly silky eyes lit up, they had already discovered this when the two countries were fighting before.

Chi Nan didn't hide it, and quickly explained the problem of the signal station, which made Weisi even more shocked.
