Chapter 391: Submarines Should Just Be Called Submarines (for Zui Yu Feng Lin, the Helmsman)

The ice steel alloy was manufactured bit by bit, and then Lu Pingxi used Dan fire to melt it together. He did not intend to manufacture ice steel plates one by one, but to manufacture a layer of submarine shell at a time.

The purpose is to prevent any gaps in the shell, otherwise, the gaps will easily become the weakness of the shell.

Lu Pingxi continued to melt in this way, and finally melted out a complete submarine shell. This shell looks like a ballpoint pen, which is cylindrical and elliptical.

After making this layer of shell, Lu Pingxi immediately arranged a formation on it and connected the power supply system of the formation with the submarine engine.

Then, Lu Pingxi began to melt the second layer of ice steel alloy shell. In this way, Lu Pingxi melted the shell layer by layer. Finally, after seven months, he successfully manufactured eight layers of ice steel alloy shells, and added the formation system and connected them to the submarine engine.

In this way, all the processes of the submarine have been basically completed.

Su Yu and Gaosu Gonglu immediately began to move the remaining materials into the submarine's warehouse, while Lu Pingxi began to build a propeller at the tail of the submarine.

With this thing, they can move forward or backward.

After the construction was completed, Lu Pingxi began to carve a new offensive formation.

This submarine can't just passively take a beating, it also needs a powerful counterattack skill!

Therefore, Lu Pingxi carved all the Five Elements Formation, the Twelve Heavenly Gods and Demons Formation, and the Chaos Formation, but using these formations will consume a huge amount of energy. If Lu Pingxi, a 10 million-level golden elixir, is not here, it would be difficult to activate these formations.

After carving these offensive formations, the submarine is basically almost completed, and the remaining are some details.

While dealing with these details, Su Yu asked, "Boss, what realm are you in now?"

Lu Pingxi said, "Same as you, early stage of Jindan."

Su Yu didn't believe it, but she didn't say it, but asked, "Boss, how much spiritual energy is in your Jindan?"

Lu Pingxi said, "More than you, about three million."

Su Yu didn't believe it even more.

Although Su Yu had entered the Jindan stage not long ago, he still knew that after entering the Jindan stage, a Jindan would be condensed. The amount of spiritual energy in the Jindan depends on your combat effectiveness and future height, so Jindan stage cultivators hope that their Jindan spiritual energy is as much as possible.

Once entering the middle stage of Jindan, the storage capacity of Jindan spiritual energy will double again. If entering the late stage of Jindan, the spiritual energy will increase to five times that of the early stage of Jindan. If reaching the peak of Jindan, the spiritual energy will reach eight times that of the early stage of Jindan.

Once reaching the Yuanying stage, the storage capacity of Jindan spiritual energy is ten times that of the early stage of Jindan!

After observing Lu Pingxi's actions for more than a year, she found that Lu Pingxi's spiritual energy was simply a bottomless pit. He was obviously working and using spiritual energy, but Lu Pingxi still did not stop to meditate to replenish spiritual energy, which was very scary.

However, Su Yu also understood that even she could not really grasp Lu Pingxi's strength and realm.

The three Jindan period cultivators began to deal with the details. A month later, the submarine was finally completed!

It was not easy. It took them more than a year to make this submarine, but the harvest was huge. This submarine was definitely strong enough for them to reach the 30th floor directly.

Moreover, the internal space of the submarine was very large, which could become their most suitable base, because it could lurk under the sea, and it was also a very good hiding place.

In addition, Lu Pingxi engraved a hidden formation for the submarine, which made the submarine a silent ghost hidden under the sea. If it wanted to attack the enemy, it could still move forward silently.

However, compared to the huge ship before, the size of this submarine is obviously much smaller. If the ship before is half the size of a medium-sized island, then this submarine is at most one-tenth the size of a medium-sized island.

Adding eight layers of thick ice steel alloy steel plates, the internal space of this submarine is even smaller.

But for Lu Pingxi and his friends, this space is already very large. Lu Pingxi does not intend to use a monster beast in the foundation-building period to drive this submarine. In the future, any crew member who wants to board this submarine must at least be a Jindan-stage cultivator.

Even if it is the little flower demon below the 20th floor, Lu Pingxi will never let them come here when they are in the foundation-building period. They must rely on their own efforts to enter the Jindan period, and Lu Pingxi will use the teleportation formation to pull them onto this submarine.

At this moment, Lu Pingxi and his friends have entered the submarine and come to the command room, which is the front of the submarine, but this command room has no glass. If you want to understand the situation outside the submarine, you can only use the cultivator's spiritual consciousness.

This is the submarine of the immortal cultivation side. Glass is completely unnecessary. After all, the defense of glass is too weak. All cultivators have it. Just use spiritual sense to check the situation outside.

After arriving here, Lu Pingxi pressed the start button, and then the submarine engine started immediately.

With a "hum", the submarine immediately vibrated, and a strong breath was emitted, scaring the small fish and shrimps around.

This submarine is equipped with too many configurations, and these configurations are too powerful, so it will generate a certain amount of pressure itself. The animals in the immortal tower are small fish and shrimps with sensitive spiritual senses, so they naturally sense this pressure and begin to flee in all directions.

But this pressure only appeared for a moment, and then it disappeared, and the sea area where the submarine was located seemed to have become nothing.

This was the activation of the concealment formation carved by Lu Pingxi.

And the vibration of the submarine also disappeared. This was a spiritual weapon-level submarine that Lu Pingxi had spent more than a year to make. Naturally, there would not be the flaw of vibrating after starting.

If the submarine kept vibrating, how could it hide under the sea?

For these powerful cultivators in the Immortal Tower, sensing a vibration is not a piece of cake.

Therefore, Lu Pingxi could not allow this vibration to occur, but it was inevitable to produce this single vibration when starting, after all, it was such a powerful engine.

The submarine engine started completely, and then a large amount of seawater was sucked into the submarine's water tank, and the submarine began to sink slowly.

After a while, the submarine completely sank under the sea, and the sea area was completely calm, as if nothing had happened.

In the command room of the submarine, Gaosu Gonglu suddenly asked Lu Pingxi: "Senior, what is the name of this submarine?"

Lu Pingxi paused. To be honest, he had never thought about the name. After all, a submarine is a submarine. Why should it be named?

Lu Pingxi thought about it, and then said: "Just call it a submarine. It is simple and easy to understand. There is no need to add more embellishments."
