Island for all: I built a home on the back of a giant turtle

The weight and buoyancy of the submarine have been calculated. When Chu Chen and four mermaids are installed inside, the submarine will float because the buoyancy is greater than gravity.

The way to make it sink is very simple. Chu Chen directly throws a large lump of sea gold from the storage space, adding weight, it will sink.

He prepared two lumps of sea gold in his storage space, the largest one, which can make the submarine sink rapidly. At this time, the buoyancy is less than the gravity!

The lump in the middle can make the submarine hover in the sea water. At this time, the buoyancy is equal to the gravity.

Put all these seabed gold into the storage space, the buoyancy will naturally be greater than gravity again, and the submarine will float up.

.

What an easy way!

As for motivation, let the mermaid patriarch use the water control ability, and Chu Chen will also have this ability.

That's why it's made so fast!

After the manufacture is completed, special instruments are used to simulate the pressure of 10,000+ meters on the seabed, and there is no problem with the submarine's ability to withstand it.

.......................................

After the submarine was manufactured, Chu Chen directly packed the small submarine into the storage space that had been expanded to 3 cubic meters, and then came to No. [-] Turtle Island, which was already in the center of the sea.

The mermaids are already here.

"Let's go~"

Chu Chen took out the submarine and got in first.

Caiwei, Shanshan, Tina, and the mermaid patriarch all got into the submarine.

One Chu Chen, three mermaids, and one little snake girl.

Under such a weight, the buoyancy of the submarine is still greater than the gravity, and it does not sink.

Chu Chen directly threw out the two lumps of sea gold.

Then the submarine began to sink rapidly.

However, the further you go down, the slower the sinking speed will be.

Because sea water is denser.

Chu Chen estimated that it would take a long time to dive for a distance of 10,000+ meters.

really.

After a long time, Chu Chen knew through the instrument that they had finally dived to a distance of [-] meters under the sea.

Along the way, I met several ancient species, but because they didn't have any sound and lights inside, the ancient species seemed not interested in this iron lump made of gold on the seabed.

The submarine continued to dive.

After a few more hours, finally, we reached the position of the moon core! .

Chapter 150

"It's almost here, brother Chuchen."

In the submarine, Caiwei's voice sounded.

Chu Chen let out a "hmm", and took away the largest lump of seabed gold in the submarine through the storage space. Then, the submarine's sinking momentum slowed down and hovered in the air.

When Tang Lei was calculating, she had already calculated the 10,000+ meter deep water, and the density of seawater was different from the above factors.

.

After the submarine hovered, Chu Chen flicked a few switches, and then, bright lights lit up around the submarine.

These lamps are naturally made of transparent sea aurite.

Otherwise, how could it withstand such water pressure.

.

Under the deep water, such a strong light can still illuminate hundreds of meters away.

A large number of pictures have appeared on the holographic screen of Chuchen Island's main watch. These are pictures taken by high-definition cameras arranged around, which are clearer than naked eyes, and can see the surrounding situation.

Now, the distance between the submarine and the lunar core is still about 100 meters away.

The lunar core with a diameter of ten kilometers is still very large, and only some changes in the arc can be seen, and it is impossible to see the entire lunar core.

The surface of the lunar core is quite smooth. It seems that after the impact, all attachments on the surface of the lunar core were knocked away.

.

"Irina, I leave it to you."

"Ok!"

The mermaid patriarch Irina activated the water control ability, and controlled the water flow behind the submarine to drive the submarine to move.

The speed is not slow.

The submarine skimmed along the surface of the lunar core, and Chu Chen also took a close look at the lunar core.

In this way, after more than an hour, the submarine finally passed the lunar core and entered the periphery of the lunar core.

After the submarine landed on the bottom of the sea, Chu Chen discovered that there was indeed a lot of seabed gold around the lunar core.

And they are all very large.

"Irina, go over there~"

Chu Chen asked Irina to use the water control ability to push the submarine towards a piece of submarine gold.

Then, Chu Chen's mental power came out.

Sea gold has a very strong blocking effect on mental power. Fortunately, this was taken into consideration when manufacturing the submarine. Tang Lei carved some supernatural patterns on the inside of a piece of sea gold in front, so that Chu Chen's mental power could at least be detected. It's about ten meters away.

This is enough.

Soon, Chu Chen's mental power "touched" the piece of sea gold, and then Chu Chen thought, and the piece of sea gold appeared in the storage space.

This is a piece of seabed gold over 10 meters long!

This kind of sea gold, in the past, was unthinkable.

.

After having a successful experience, Chu Chen continued to let Irina control the submarine to move. This time, he only picked large pieces of seabed gold.

Of course, it's too big to fit in.

The current storage space is [-] cubic meters, don't think it is too big, it is just equivalent to a cube with length, width and height.

But don't think it's too small, because the storage space is not a cube. Putting things in it is not like ordinary things, piled up in a pile.

The things put in are all independent, as long as the total volume of these things exceeds [-] cubic meters.

Dozens of pieces can still be placed in such a seabed gold that is more than 10 meters long.

.

Even so, due to the surrounding seabed gold is too much.

In less than an hour, all the sea gold was packed into the storage space.

Then, Chu Chen let the submarine float up, put all the sea gold back into the warehouse on No. 1 Turtle Island, and then turned back to continue the process.

......................................

The second time I dived Chu Chen let Irina directly use the supernatural power to speed up, which was much faster.

In this way, back and forth, the final time is about 3 hours.

then.

Chu Chen went back and forth in this sea area to collect sea gold with a frequency of four to five times a day.

Chu Chen collected this collection for half a month.

Although it took half a month, Chu Chen gained a lot.

In the warehouse on Turtle Island No. 1, sea gold has piled up into mountains!

With so many sea gold, Tang Lei was shocked enough!

.

It can be said that the sea gold collected in the past half month can be used for Tang Lei to do too many things.

Many whale warships can be built, and these submarine gold can also be used to build the armor of ordinary warships.

As for the sea gold needed for the equipment of the mermaids, there is no need to search everywhere anymore.

"You can rest for a while."

Chu Chen was also a little tired after working on this job for half a month. Fortunately, every night, the little mermaid Caiwei and the little snake girl Tina would massage his head to soothe him.

.

These submarine golds are enough for a long time.

When it is used up, the mermaids will also evolve. At that time, the mermaids can collect the sea gold without Chu Chen doing it himself.

"Collect it again!"

Seeing that it was only afternoon today, Chu Chen decided to collect sea gold again, and would not do it again tomorrow.

Soon, he dived underwater again and quickly filled the storage space.

"Go back~"

Chu Chen put all the seabed gold into the storage space, and the submarine began to float up.

"Brother Chu Chen, wait a minute~"

At this time, the voice of the Little Mermaid Caiwei sounded.

"What's wrong, Caiwei?"

Chu Chen asked.

"Brother Chuchen, look` `~"

Caiwei pointed to the lunar core captured by a high-definition camera on the holographic screen, and said.

When Chu Chen saw it, his eyes paused.

because.

On the top of the moon core, there are some symbols!

These symbols seem to be engraved on the moon core!

....................................

"what is this?"

Chu Chen whispered.

"Let's go and have a look."

The submarine headed towards the lunar core, and soon arrived nearby. Now, I could see it more clearly.

There are indeed symbols on the lunar core, which is composed entirely of seabed gold, and there are not just one symbol, but many symbols.

Submarines follow these symbols.

Chu Chen discovered that these symbols covered a large area and formed a huge figure.

Then, right in the middle of these figures, he found a pattern of a door.

"Door?"

The submarine flew near there, and the door, which looked like a pattern, didn't seem to be a real door.

The door is very big, if it is a real door, submarines can go in.

.

Around the door, there are also a large number of patterns, which seem to be some exquisite pattern decorations.
