Happy May Day, today is more, thank you for your support.

After many tests, and even Chi Nan pulled many researchers to test together, this new water explosion bomb was finally completely formed. In addition to not being able to be used on land or in the air, in the sea this kind of water bomb is no less powerful than a Bat missile.

"With the waterburst bomb, the submarine basically has a complete deterrent force. The torpedo moves slowly, but has a longer range than the Bat missile. Then the submarine itself, as long as the ice cannon is enough, this configuration is similar to that of an airship. Ice arrows don't need to, but they don't have to be removed completely, and ......"

Chi Nan's eyes narrowed slightly: "Since there are so many underwater submarines, then the underwater aircraft carrier should also be manufactured." A complete platform is needed underwater more than in the air, just like airship carriers. ”

Chi Nan began to experiment whimsically. Soon, a deep-sea carrier modeled after an airship carrier was created. The shape is a little different because it's more streamlined.

And because of the buoyancy of the seawater in the sea, the size of the deep-sea carrier can be made even larger. There are also more torpedo launches, so there is a strong attack capability.

Eventually, Chi Nan added the kind of plant that he found from the Sea Spirit clan that could produce bubbles. When the mothership docks with the submarine, or when it is needed, it will directly produce bubbles to repel the surrounding water. This makes it easier to work underwater. "It's just that in this case, it's still a bit monotonous. ”

"If there are hummingbird fighters in the air, then there should be one in the water, not just the mothership itself. Without combat units, what kind of mothership is a mothership. Chi Nan set his sights on those manta rays.

After a week of struggle, these manta rays were finally studied and penetrated by Chi Nan. In the water, a new combat unit has appeared, something that looks similar to a manta ray, and can easily accelerate in the water.

There are two things, thrusters and water flow controllers, and the speed of this manta ray fighter in the water is very close to the speed of the hummingbird fighter. And in terms of flexibility, it is higher than the Hummingbird fighter.

"It's a pity that the ice cannon can't be installed on this, that one is too big, and only ice arrows can be installed. ”

Chi Nan placed the ice arrow on the body of the manta ray fighter, and it was not one, it was two. One underneath each of the two wing-like things. When it was fired, the ice arrow launchers on both sides were fired one after the other, full of power and coherence. It may be less destructive than the wind cannon, but the firing speed is incomparable.

These Manta Ray fighters are flat in size and look much larger than the Hummingbird fighters. However, because it is too flat, it can be easily stacked together, and more can be packed into the same space.

Once the war begins, the mothership is able to easily unleash an overwhelming array of Manta Ray fighters. These manta ray fighters can even fly at ultra-low altitude on the sea, even if they fight on the sea, there is no problem.

The attack of condensed ice arrows can easily form the effect of ten thousand arrows at once. And it's all magic, not a human archer. When the quantity increases, there will also be a qualitative change.

"Finally, with the addition of the self-detonation type, it is the same as the airship formation. But this self-detonation, forget it, let's study it later. ”

Chi Nan put the self-detonating submarine down for the time being and began to study the underwater base instead. That's right, underwater bases. The buoyancy in the sea water is so strong, Chi Nan doesn't want to waste it like this.

Since the buoyancy is large, then continue to expand the size of the underwater carrier, and in the end, it is better to simply make it into a base. Chi Nan thought of the war fortress, didn't this thing sink underwater before? Simply, Chi Nan was directly transformed with a war fortress and transformed into a situation suitable for underwater survival. Unsuitable weapons, take them all.

Those super cannons are useless in the sea. Simply, it would be better to replace it with a larger torpedo. The main thing is that this base is needed, and with this activity base, it will be possible to produce a large number of submarines at any time to replenish it.

Even such a large base is capable of continuously producing motherships. On the surface, this seems to be an enlarged deep-sea carrier, but in reality it is not like this at all.

It's not just a matter of amplification, but the most important thing is that this kind of production capacity is completely incomparable to that of deep-sea carriers. Pond Nan's intention is to use the underwater base as a standard, and then to study the underwater city. Once the underwater city is successfully established, I believe that the benefits will be even greater.

It's a pity that the establishment of a city is completely different from a military fortress, the city pays attention to comfort, and to build an underwater creation of this scale, it is not something that can be completed by Chi Nan alone.

After finally giving the order to study, Chinan left most of the design work to someone else.

At this point, the underwater submarine formation was thus completed in the hands of Chinan. Chi Nan didn't bother to use other standards, and directly adopted the same standards as air formations. Each of the four motherships carries thirty submarines, which directly form a formation. Using this as a standard, submarine formations under water began production without a sound.

People from the outside world didn't know that such a major change had taken place under the water of the Holy Tree Territory unknowingly.

"Both the mothership and the underwater base are seriously not in line with the underwater environment, and now they are only slightly modified. In the future, various problems are discovered, and continuous improvement is needed so that it can adapt to the underwater. ”

You don't need to bother yourself with this problem. As long as you have formulated a big framework and completed the main body, the next modifications have nothing to do with you. Although Chi Nan wants to find something to do, he will not make trouble for himself.

Because at this time, Chi Nan has found a new research direction. In the past few days, with the continuous cultivation and transformation of the twin trees, Chi Nan's ability to transform the magic pattern has become more and more powerful. Now, Chi Nan is working on a new wind cannon concept. After adding the fire-attribute magic pattern, Chi Nan plans to research a new plant weapon on his own.

The recent research on deep-sea formations has allowed Chi Nan to accumulate a lot of knowledge. He also has a deeper understanding of the transformation methods of various magic patterns, which is the reason why Chi Nan has moved to improve the wind cannon.

From the beginning, the wind cannon was the most powerful weapon in the territory, but now it has become a chicken rib because of the range problem, and it is impossible not to be depressed. It's just that I haven't found the direction of improvement, so I'm dragging it out.

Now, with the ability to transform the magic pattern, after a lot of experiments, I can finally improve it.
