Originally, Lu Pingxi could directly use the power system of this sea ship to design the submarine's power system.

But Lu Pingxi still felt that this power system was a bit bad. The power system of this sea ship was very simple. This is an instrument that can convert spiritual energy into five attribute energy. This may be related to the five elements combined attack formation of Haixian Pavilion.

They knew a lot about this formation, so they used this formation to create a power system.

Once this system is built, it only takes a spirit stone into the system to drive the entire sea ship. However, this efficiency is too low and not enough for submarines to use.

For a submarine, what is required is not only the kinetic energy of the engine, but also the electric energy of the entire ship and the powerful pressure energy of the sea water. Therefore, the submarine's requirements for the energy system are very high.

So if you want to build such a power system for submarines, the best thing is the nuclear engine.

With Lu Pingxi's current identity, status and strength, it is probably not difficult to find the joint army to ask for a design drawing of a nuclear submarine. But the problem is that Lu Pingxi has not found uranium in this fairy tower. Without uranium, Lu Pingxi will no longer have the raw materials for the nuclear engine. So what's the use of manufacturing a nuclear engine?

So Lu Pingxi had to find ways to build other engines and other power systems, and this was really not an easy task.

After thinking for a long time, Lu Pingxi still planned to copy the jade disc circuit directly. This jade disc circuit can absorb all energy for his own use. The circuit almost touches the origin and is a very powerful and very practical circuit.

However, there are too many ways to do this. Even Lu Pingxi wants to copy 90% of the time.

However, this time, only a small part of the circuit is required to build a submarine engine.

All Lu Pingxi needs is the circuit that can transform spiritual energy and evil energy into each other, and this circuit has it.

With this part of the circuit, Lu Pingxi can add the Five Elements Formation and Chaos Formation to the engine, so that it can be used to provide five different attributes of spiritual energy.

Among them, the combination of fire-attributed spiritual energy and water-attributed spiritual energy can generate huge energy, and then install a generator to generate electricity.

Wood-attribute spiritual energy and water-attribute spiritual energy can be used to grow herbs.

Metallic aura and earth-attributed aura can be used to protect ships.

In addition, the most favorable condition for using evil energy to provide energy is that while they continue to kill sea monsters, these evil energy can be replenished into the submarine's engine. In this way, just killing can replenish energy.

After all, sea monsters will cull when they see monks, so they will definitely encounter attacks from sea monsters during their stealth under the sea. In this case, killing the invading sea monsters and using evil energy to replenish energy can be said to be a by the way.

It is also worth mentioning that after killing the sea monster, the inner alchemy of the sea monster can obtain the sea monster's inner alchemy. These inner alchemy contain this extremely rich spiritual energy, but these spiritual cultivators cannot absorb it directly. They must refine the impurities after a long period of refining.

But this submarine engine is different. This submarine engine does not need to refine any spiritual energy at all. Whether it is the inner alchemy of the sea monster or the golden alchemy of the monk, it can directly provide energy for the submarine engine.

In this way, they can obtain energy well as they move forward.

After Lu Pingxi designed the submarine engine, he immediately started to make it. He used fire crystal ingots, which are heat-resistant and can produce heat by themselves, so they are very suitable for making the engine core.

The only difficulty is to carve the loops in the engine, which is time-consuming.

However, Lu Pingxi didn't think it would be possible to lose some time. The process of manufacturing a submarine now is equivalent to sharpening the knife. The knife will sharpen it so that it will work well in the future.

Moreover, it is best to design this submarine at one time, otherwise it will be difficult to modify any defects when detected in the future.

Lu Pingxi started to make this submarine engine, and it took three months to do it. The most important part of this engine took Lu Pingxi three months, and finally it was successful after repeated tests.

In this way, the core of the submarine was completed, and Lu Pingxi's understanding of the jade disc circuit was also a little higher, and he had gained something in the past three months.

After the submarine core was completed, Lu Pingxi immediately called the expressway highway and Su Yu to make the internal cargo holds of the submarine. Some of these cargo holds are used to accommodate people, some are used to grow herbs, some are used to store gas, and some are used to store cargo.

In short, the next process does not require any IQ, but a repetitive work.

They need to splice the submarine cargo compartments one by one, and then surround the submarine engine, so that the submarine core is at the center and in the safest place.

Moreover, you cannot just make one core thing. In addition to the central core, the head and tail of the submarine must be made into another core, which is called third-hand preparation.

The following project volume was also huge, and the three Jindan periods immediately became busy. After half a year, they finally successfully built and spliced ​​all the submarine cargo holds.

During the whole process, everyone was using their own spiritual consciousness and spiritual energy to create cargo holds with the means of controlling objects, which was also a means to exercise their own skills in controlling objects.

After they spliced ​​all the cargo holds, Lu Pingxi carved arrays one by one on the cargo holds. With these arrays, air, energy will be transported to these rooms, and the electrical energy converted through the engine can also be transmitted.

Lu Pingxi is not an ancient submarine. The submarine he made has electricity. Maybe it can install electrical appliances in the future, watch TV, play with computers, and use refrigerators.

Since he wanted to submarine early, he naturally had to integrate the knowledge on the scientific side and the knowledge on the immortal side. In the future, he might be transformed into a space warship or something.

He heard that on one of the tenth floors of the immortal tower is the land of stars.

But don’t care about those, now, after the cargo hold is spliced, the shell will be started.

Lu Pingxi has high requirements for the shell. After all, this submarine needs to follow them and directly reach the 30th floor.

If the shell is not hard enough, it will not be able to withstand the huge pressure of the deep sea.

Therefore, the ling steel made by Lu Pingxi from Ling Iron ore and the ice steel alloy formed by the fusion of Ling Iron and Ice Crystal Ore came in handy.

Lu Pingxi plans to use this ice steel alloy to create a shell and a hard shell of spiritual weapon level!

In Lu Pingxi's design, this shell requires at least eight layers, and each layer is engraved with formations to reinforce. He wants to build a submarine that is hard enough to block the siege of the Jindan stage monks!
