Recently, the development seems to have entered a peak period, and various bottlenecks have been broken through. This time, Chi Nan found a new transparent material, which is much stronger than the previous material.

This transparent material, only in its own hardness, is a little worse than diamond wood, but its own toughness is far from being comparable to diamond wood, it can be said that each has its own strengths.

With this kind of thing, Chi Nan directly replaced all the windows on the airship. And this kind of window can also be used on ships. Recently, Chi Nan transformed the magic pattern on the lifesaving wood, and finally formed a special magic pattern that he needed. This is a modification that mimics the thruster pattern.

Because the lifeguard is inherently capable of controlling the flow of water, it is fairly easy to modify. Using the method of controlling the flow of water, the thruster is able to compress and repel the water flow in large quantities with the help of the water element, and then form a propulsion force.

With this new power, you can get a speed bonus of several times the speed of your own boat in the water at once. And the underwater submarine has finally come out in the hands of Chinan.

During this time, Chinan has been designing submarines. The water route to the mainland and the Sacred Tree Island has always been very problematic, and I can only ensure that this section of the patrol is relatively safe.

However, there is no way to solve the underwater danger, and there are still frequent problems with ships.

If it weren't for the fact that there were really few people on these ships, I'm afraid that many people in the territory would have complained.

But with the advent of submarines, this problem will certainly be solved. "Yes, yes, it's much faster than a boat, it's small after all, and it's streamlined. ”

Chi Nan is controlling a submarine to navigate the water, while he observes and records from the shore.

After all, he has to go underwater, and once there is a problem, he will die, even Chi Nan will not rashly let himself fall into this danger. Anyway, for yourself, plant weapons are like remote-controlled toys. No, it should be said that it is easier to control than a remote control toy, because he doesn't need a remote control.

After sailing for a long time, the speed and turning have been tested, and Chi Nan is very satisfied. "In the water, it is easier to transmit information than in the air, and this is probably because of the special situation of plant brain communication. ”

It is incredible that Kenan discovered that seawater is not an obstacle to communication, but can promote the smooth flow of communication.

Finally, that's weapons. It is precisely because of the problem of weapons that Chi Nan has never made submarines. The previous thrusters didn't work, and if you wanted to install the missile inside the submarine, it didn't work.

"Patriarch, this is the submarine you made, it looks interesting, it can fight underwater. But what about weapons, and didn't you say that there are a lot of problems underwater? ”

Chi Nan nodded lightly: "That's right, there are many problems, but relying on the plant brain to cooperate with the perception of plants, plus the searchlight installed on it, the observation is generally feasible." "My own submarine does not use sonar, but plant perception. This type of perceptual plant was also found in the waters of Sacred Tree Island not long ago.

"As for weapons, I'll let the submarine launch it for you. "In the water, air cannons and wind cannons are unusable and have no power. If you use a cannon, you can even hurt yourself.

Chi Nan chose fish and missiles, or just similar fish and missiles.

The current thruster is mounted in a streamlined shell that resembles a fish, and suddenly fires out, eventually taking up a white line like a fish. From a distance, it looks like a shark swimming fast.

The "boom" fish hit a model of a ship that was targeted in the distance, and an explosion suddenly sounded. Although this fish only has the explosive power of the silver level, because of its larger size, the damage range is also more extensive.

The hull of such a hard ship was hit, and a large hole was blown open on the spot. Sea water poured into it. If it weren't for the fact that the cabin has many sealed compartments, I'm afraid this would have silenced it.

This kind of destructive power can be said to be placed overseas, except for the magic defense ships of the Silan family, ordinary ships don't want to block a cannon at all. At this moment, the surface of the water suddenly exploded, and two missiles broke through the water blockade and flew into the air. At high altitude, the wings shifted, which led to a change in the trajectory of the missile.

From ascent to level flight, then to descent, the target is precisely that model ship.

"If it weren't for the thrusters that can launch smoothly, this kind of underwater launched missile really can't be made. ”

Chi Nan said to himself, because there is no air in the water, the missile was not launched directly. The first is the use of the wind element, which forcibly sprays the wind element to send the missile above the water.

There are few underwater wind elements, but not nothing, and this missile can still be affordable with a small amount of use.

When it flies to the surface, the missile will change the thruster effect and change it to guide the air to form a wind, which in turn will produce a propulsion effect. That's why the missile pauses as soon as it breaks through the water.

This time is very short, ordinary people can't notice it at all, even if they can get to it, I'm afraid there is no way, this is on the water. It's not too big, it's not the kind that can reach the gold level of destructive power.

But when the two missiles accurately hit the model ship, there were two more explosions, and the ship was blown into several pieces, and it fell silent. Speaking of which, this ship model is really sturdy enough, and it hasn't been shattered like this. Sure enough, the plants you make yourself are powerful, even if it's just a model.

Chi Nan praised himself in his heart, and then turned his head to look at Miria next to him.

Miria, a half-elf who doesn't do her job, doesn't do her own thing, and actually runs out again.

"Are there only these two means of attack, this is too one-dimensional. ”

"It's easy to use, what does it matter if it's single. Chi Nan said indifferently. Miria didn't know that because of the small size of the submarine, not only was there a single means of attack, but there were also few fish and missiles.

In the heat of battle, you will soon run out of ammunition and then have to replenish it. But this is the first weapon used for underwater attack after all, and once it is used, even the Silan family will probably suffer a big loss.

Without continuing to talk nonsense with Miria, Chi Nan took out a lot of seeds and said, "Since you don't have anything to do, then take these things overseas and build a submarine secretly." Remember, the stakes are high and don't let too many people know. ”
