National Island: I Build 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 inside, the submarine will float because the buoyancy is greater than gravity.

The way to make it sink is very simple. Chu Chen threw a large lump of seabed gold directly from the storage space, and if the weight increased, it would sink.

He has prepared two lumps of seabed 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 allows the submarine to hover in the sea, and the buoyancy is equal to gravity at this time.

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

.

What an easy way!

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

So, it was made so fast!

After the manufacture is completed, the pressure of hundreds of thousands of meters on the seabed has been simulated through special instruments, and the submarine can withstand it without the slightest problem.

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

After the submarine was built, Chu Chen directly put the small submarine into the storage space that had been expanded to 6,400 cubic meters, and then came to Turtle Island No. 3, 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 a little snake girl.

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

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

Then the submarine began to sink rapidly.

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

Because sea water is denser.

Chu Chen estimated that at a distance of more than 100,000 meters, he might have to dive for a long time.

really.

After half a day, Chu Chen knew through the instrument that they had finally dived to a distance of 100,000 meters under the sea.

Along the way, I met the ancient species a few times, but because they didn't have any sound or lights inside, the ancient species didn't seem to be interested in this iron lump made of seabed gold.

The submarine continued to dive.

After a few more hours, finally, the location of the moon core was reached! .

Chapter 150

"It's almost here, Brother Chu Chen."

Inside the submarine, Cai Wei's voice sounded.

Chu Chen made a sound of "um" and took away the largest lump of undersea 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 doing the calculation, she had already calculated that the density of seawater was different from the above factors at a depth of hundreds of thousands of meters.

.

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

These lamps are naturally made of transparent seabed gold white crystals.

Otherwise, how could it be possible to withstand such water pressure.

.

In the deep underwater, such a strong light can still illuminate hundreds of meters away.

On the holographic screen of Chu Chendao's main watch, a large number of pictures have appeared. This is the picture taken by the high-definition cameras arranged around it. It is clearer than the naked eye, and it can see the surrounding situation.

Now, the distance between the submarine and the moon's nucleus is still about 100 meters away.

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

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

.

"Irina, leave it to you."

"Um!"

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

Not too slow.

The submarine skimmed along the surface of the lunar nucleus, and Chu Chen also observed the lunar nucleus up close.

In this way, after more than an hour, the submarine finally swept past the lunar nucleus and entered the periphery of the lunar nucleus.

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

And they're all unusually large.

"Irina, go over there~"

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

Then, Chu Chen's mental power reached out.

The seabed gold has a very strong blocking effect on mental power. Fortunately, this was taken into account when making the submarine. Tang Lei engraved some power lines on the inside of a piece of seabed gold in front, so that Chu Chen's mental power could at least be detected. Ten meters away.

This is enough.

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

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

This kind of seabed gold, in the past, I dared not think about it.

.

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

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

The size of the storage space is now 6,400 cubic meters. Don't think how big it is, it is equivalent to a cube of length, width and height.

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

The things put in are independent, as long as the total volume of these things exceeds 6,400 cubic meters.

Such a seabed gold with a length of more than 10 meters can still be put in dozens of pieces.

.

Having said that, because there is too much gold in the seabed around.

It only took less than an hour, and all the seabed gold was put into the storage space.

Then, Chu Chen let the submarine float, put all the seabed gold back in the warehouse on Turtle Island No. 1, and then folded back to continue the process.

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

The second time I dived into Chu Chen and let Irina use the ability to accelerate directly, it was much faster.

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

then.

Chu Chen collected seabed gold back and forth in this sea area at a frequency of four to five times a day.

This collection, Chu Chen has collected for half a month.

Although it took half a month, Chu Chen's harvest was huge.

In the warehouse on Turtle Island No. 1, the seabed gold has accumulated into a mountain!

With so much undersea gold, Tang Lei was shocked enough!

.

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

There are many whale warships that can be built, and these seabed gold can also be used to build the armor of ordinary warships.

As for the seabed gold required for the equipment of the mermaids, there is no need to look everywhere.

"You can rest for a while."

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

.

This sea gold is enough for a long time.

When it is used up, the mermaids have also evolved. At that time, the mermaids can collect the undersea gold without Chu Chen doing it himself.

"Collection again!"

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

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

"Go back~"

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

"Brother Chu Chen, wait a minute~"

At this time, the voice of the little mermaid Caiwei sounded.

"What's the matter, Caiwei?"

Chu Chen asked.

"Brother Chu Chen, look ' ' ~"

Caiwei pointed to the moon nucleus captured by a high-definition camera on the holographic screen, said.

Chu Chen looked at it, and his eyes suddenly stopped.

because.

There are some symbols on the moon core!

These symbols are like those engraved on the moon core!

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

"what is this?"

Chu Chen whispered softly.

"Let's go and have a look."

The submarine headed towards the lunar nucleus and soon came to the vicinity. This time, I could see it more clearly.

There are indeed symbols on the moon core, which is entirely composed of seabed gold. These symbols are not only one, but many.

Submarines follow these symbols.

Chu Chen discovered that these symbols, covering a relatively small area, formed a huge figure.

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

"Door?"

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

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

.

There are also a lot of patterns around the door, which seem to be some delicate pattern decorations.
