Luckily, Du Le soon found the answer he was looking for in the Butler's database.

Du Le is interested in an intelligent underwater exploration ship. From the perspective of all conditions, it is currently the most suitable underwater equipment for the actual situation of the island country.

This intelligent underwater exploration submarine is originally used for the study of the living habits of marine organisms, so it is a scientific research equipment.

Its most significant advantage is that it can operate in the water for a long time, and can even withstand a certain amount of pressure, and has a certain degree of freedom in the deep-sea position. In addition, because this detection submarine has a sonic detection function, it can be set up according to the data to complete the task of searching for life on the bottom of the sea. This is a great help for the search for specific targets at the bottomless depths of the sea.

However, with so many advantages, this smart submarine does not have a bloated size, but is not as large as a hatchback. Therefore, on the whole, for an island country surrounded by the sea, having this kind of intelligent submarine naturally adds a lot of strategic advantages.

Because, the main reason why Du Le likes this smart submarine is because after thinking, Du Le found that after a few simple transformation and design, this underwater exploration ship can be transformed into a submarine automatic patrol submarine, so as to upgrade it from an ordinary scientific research equipment to an indispensable marine strategic equipment.

Du Le imagined that if he had this underwater detection ship, he would be able to carry out non-stop patrol missions in the depths of the sea, and maybe he would be able to find out the location of enemy submarines in advance.

When you think of these exciting design options. Du Le couldn't help but start to be whimsical. Perhaps, we can also make a bold move, after converting these underwater detection ships into automatic patrol submarines, and adding deep-sea torpedo devices to increase the ability to launch torpedoes. In this way, it is possible not only to increase the aggressiveness of the ship, but also to increase the concealment of the torpedo launcher.

And. Judging from the drawings of this intelligent underwater exploration ship provided by the Almighty Butler database. Despite its small size, it was not difficult to install a full set of torpedo launchers.

What's more, Du Le is not completely out of the question. Adjustments were made in terms of torpedo guidance techniques and the shape and volume of torpedo devices. Even. In fact, Du Le can also make the guidance technology intelligent. So. Although this scheme is only Du Le's imagination at present, its feasibility is obviously still very large.

In fact. In the Almighty Butler database, the description of the production process of this detection submarine is not complicated. The only slightly troublesome part is the energy drive, and the metal requirements for the submarine hull.

Energy drive, there is no doubt that it is energy stones that are needed. Because seabed tracking and exploration is actually a "protracted war", a project that requires patience and time. Therefore, although the volume of the detection submarine is not large, according to the design of its energy tank, it still needs at least one standard energy stone to maintain its operation. As long as this sufficient energy demand is met, each exploration submarine can operate uninterrupted, at least for about 100 days, after each dive to the bottom of the sea.

And with regard to the hull of the submarine, the requirements are even more stringent. In order to be able to withstand the huge pressure of the deep sea, the requirements for the metal material of the submarine hull are naturally higher.

On the other hand, most of the countries that have submarines in the world today use alloys or titanium alloys in the production of submarines for military or scientific research in order to resist the huge pressure on the seabed. Because this material has the advantages of low specific gravity, high strength, high temperature resistance, strong corrosion resistance and non-magnetism, it has been widely used.

But for Dule, he will not rest on his laurels at this stage. Because in the deep sea, a combat site with high unknown and high danger, which side has a higher level of equipment and toughness, the probability of victory is naturally higher. In this regard, Du Le has paid attention to it, and remembers that some experts in related fields seem to have proposed that in the future, glass materials can be used to build the shells of deep-sea submarines. So, Du Le thought about whether he could try it on his own, if it really didn't work, or go back to Andromeda one day to find some more suitable designs to learn from.

Of course, that's all for later, and Du Le doesn't need to completely copy the function of detecting submarines, and transformation is inevitable. Because all of these ideas must be based on careful consideration and planning of the smart factory workload.

However, the 3D printers of the smart factory are now working hard to produce the production line equipment for space fighters and the production line equipment for laser cannons. But that's not all, there's a mecha production line waiting next to it. Therefore, if other new production lines are arranged on this production list in a short period of time, it will not be able to cope at all.

If the alien fleet wasn't coming, and there was plenty of time for Du Le to study slowly, it didn't matter how much was waiting for him. But at present, it is natural that the main task should be to reach the alien fleet, so all ideas must be implemented quickly in order to prepare for the war in advance.

Du Le suddenly had a flash of inspiration in his mind, he might as well transfer the production tasks of these patrol submarines to other powerful countries to share, and he could choose to place orders with the submarine production factories of these countries. In this way, Du Le does not have to carry so much by himself, and even has to directly build a production line for patrol submarines, so he can focus more on dealing with the problem of the alien fleet.

Dule's first choice is naturally the shipyard of Huaguo.

Du Le has already carried out trade cooperation with China more than once, so the relevant trade barriers are naturally less than those of other countries, and the cooperation will be smoother. Moreover, relatively speaking, Du Le's trust in China is also higher than that of other countries.

Du Le's requirements are not too high, as long as he can produce at least 50 patrol submarines in the next six months and deploy them in the waters of the island country.

Of course, we will have to wait for discussions with the Chinese side to see how China will reply before making a separate decision.

Therefore, in the first step, Du Le needs to let the all-round butler design a relatively easy to operate, small patrol submarine manufacturing plan, before he can discuss it with the relevant parties in China.

The efficiency of the all-round butler was very fast, and in a short time, according to Du Le's request, he completed this task.

The manufacturing solution is divided into three parts.

The first part, the fuselage of a patrol submarine. This part will be handed over to a powerful and reputable shipyard to be responsible for the completion of the manufacture.

The second part is the energy drive box. This part is also easy to solve, and if necessary, it is also possible to use the energy cartridge of the hovercar to deal with it.

The third part, on the other hand, is the assembly part, which can be done by an engineer robot.

Because patrol submarines, in essence, are small unmanned autonomous submarines. Therefore, after the completion of manufacturing, Doul does not need to do any special tests to check its performance, etc. Therefore, Du Le will think that in the short term, it is feasible to create patrol submarines.

Without further ado, after the manufacturing plan was confirmed, Du Le immediately copied the fuselage design of the patrol submarine.

After thinking about it, Du Le waved his hand, asked Pan Huan to leave, and called Chen Chen again, and handed over all the design materials and requirements to Chen Chen. Du Le decided that Chen Chen would be in charge of ordering patrol submarines.

After solving this matter, Du Le took his parents home and had a good night's rest, and it was not until the next day that Du Le took two bodyguards and boarded a flight to country M together.

But after Du Le and his party got off the plane and walked out of the airport in country M, Du Le soon sensitively noticed that the situation was a little strange.

Doole appears to be under surveillance.

When Du Le found that behind him, there were always so many people who looked suspicious but deliberately hid themselves to follow, Du Le couldn't help but wonder in his heart, did the intelligence bureau of country M have received any news before he will be targeted?

Suddenly, Du Le stopped, and he thought of the biggest possibility - is all this related to the theft of the island Academy of Sciences? If Du Le's guess is correct, it is almost certain that these people behind him must be inseparable from the instructions of the Intelligence Bureau of Country M.

In the interval between Du Le's secret speculation, some reporters from country M who heard the wind saw Du Le's figure, so they leaned over to Du Le, wanting to interview Du Le. The topic of their interview is still related to Longxiang suspension car. But Du Le had something important to do, so he didn't plan to delay any longer and accept interviews with reporters.

As for these sneaky guys behind him, Du Le doesn't plan to pay attention to them, anyway, in the two days he stays in country M in the future, Du Le doesn't plan to do anything special. Therefore, since the people of country M want to spy on him, come casually, as long as it doesn't affect him, what you want to do, Du Le doesn't worry.

During these two days, Du Le carefully observed the places he passed through in country M, trying to find some suitable teleportation coordinates so that he could come and go freely in country M in the future.

After consideration, Du Le finally chose one of the restaurants in the hotel where he lived. In the restroom of this restaurant, Du Le set up a teleportation coordinate.

At the same time, Du Le also deliberately set aside a spy machine in this toilet to be responsible for the environmental monitoring of the bathroom.

Then, for the rest of the time, Du Le behaved in a way that was a big surprise. Because not only did he not run around and get into trouble, but he just lived in the hotel. In addition to enjoying food, massages and other services, Tule almost never leaves the hotel room.

In this way, after spending two days peacefully, Du Le flew directly back to the main island of the island country.

The one who felt the most headache about Du Le's bizarre behavior was naturally the director of the Intelligence Bureau of Country M. Khufu. (To be continued......)
