National Island: I Build a Home on the Back of a Giant Turtle

In this way, after a few days, Chu Chen and the mermaid queen's induction began to become clear.

Clear induction, which means that it's almost here!

Chu Chen was refreshed and swam straight in the direction of induction.

In this way, after swimming for more than an hour, Chu Chen sensed again that the location of the mermaid queen should be underwater!

"Should be below ' ' ."

Chu Chen thought.

Thinking of this, Chu Chen plunged into the sea water and began to head towards the bottom of the sea.

.

The underwater volcano where the lava prison that holds the Mermaid Queen is located is not the same as the underwater volcano in the area where the No. 4 Industrial Island is located.

The submarine volcanoes here do not erupt on a large scale.

Looking at the sea, it is impossible to see that there are volcanoes below.

Moreover, the sea people did not set up vigilance on the sea.

However, as Chu Chen dived, he began to discover that a dense school of fish appeared in the sea.

When he discovered this shoal of fish, Chu Chen did not say a word, and directly activated the stealth ability shared from the ancient octopus.

Into a stealth state.

The mermaid queen told Chu Chen about this kind of fish. It was a kind of fish raised by the sea people, and it was quite alert.

Once they found Chu Chen, then in the prison, seamen with special abilities could find Chu Chen.

.

Ancient octopuses are now invisible for much longer than they used to be.

After sharing, Chu Chen can remain invisible as long as he doesn't move in the sea.

If active, it can last up to two hours at a time.

Then it will take a while to activate.

Two hours, in Chu Chen's view, was enough.

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

In this way, Chu Chen continued to dive.

In the sea water, there are a lot of that kind of fish, they form in groups, and they will besiege the fish that break into this area, turning those fish into their food.

Chu Chen avoided them and continued to dive.

In this way, after diving for more than 3,000 meters, Chu Chen found a faint light under the sea water.

"arrive."

Chu Chen whispered softly.

That should be the red light brought by the crater of the underwater volcano.

He continued to swim there.

After swimming a few hundred meters further, the sea water has some temperature.

The crater can already be seen.

Just under two hundred meters.

However, the crater is surrounded by high walls. These walls are dozens of meters high. They surround the submarine crater with a diameter of several hundred meters. At the top of the wall, from the four corners of the wall , each with an arched beam several hundred meters long.

Two beams, in the form of a cross, rest on the four corners of the wall.

In addition, in the middle of each wall, there is also a beam.

There are four beams in total, forming a "rice" shape.

On these arched beams, at intervals, there are some dark chains hanging straight down, all the way into the crater below.

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

"The ones hanging under these chains are the prison cells, right?"

Chu Chen looked at the chains and thought.

The mermaid queen told him about these chains.

The length of each chain has reached thousands of meters.

They are made of seabed gold, each chain is quite thick, and the thickness is used to achieve the effect of heat insulation.

Between them, there is a tube that wraps the seawater circulation.

The temperature of the underwater volcanic magma is higher and higher.

In other words, these cells are hundreds of meters below the lava lake!

Moreover, these chains can still be completely put down, that is to say, in case someone comes to violently rob the prison, the guards of the sea people can choose to completely loosen the chain and let the cell completely fall into the lava lake.

.

After reading the middle area, Chu Chen looked at the high walls.

At the top of the high wall, there is a row of buildings, and the people living in those buildings should be the sea people.

Chu Chen had never seen a sea man before, so he didn't know what was the difference between him and a human being.

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

Above the underwater prison, there are the kind of dense fish raised by the sea people.

This kind of saying is also a vigilance and reconnaissance method often used by sea people.

According to the mermaid queen, these fish have a very rare feature - shared vision.

As long as the fish born from the same batch of eggs are not separated by more than 100 kilometers, they can have the vision of other fish in the school.

Then, a small number of seamen with special abilities can catch a fish from each fish group and put it by your side, and you can get the vision of all fish from that fish!

This is also the reason why this lava prison is so difficult to break into.

Although the sea people do not have the scientific and technological means of human beings, there are still many sea people with special abilities.

.

In addition, if it wasn't for the telepathy between Chu Chen and the Mermaid Queen, in the boundless sea, who would have known that there would be such a lava prison in this seabed?

If it weren't for the effect of telepathy, Chu Chen might not have been able to find it after hundreds of thousands of years.

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

"As long as you avoid these fish, you should be fine."

Chu Chen pondered for a while, and then swam down silently.

He shared the superb water quality from the killer whale, and the ability of the sea whisperer from the mermaid patriarch Irina. The current Chu Chen can be said to be the darling of the sea, and his swimming in the sea is also silent. .

In this way, Chu Chen came to the top of the underwater prison soon, and he could already see the lights and some figures in those buildings.

Around the territory, you can also see the figures of the sea people swimming.

These figures, it seems, are similar to the human body, but there must be some differences in details.

.

Chu Chen did not observe these seamen too much, and the mission of this trip was to rescue the mermaid patriarch.

He dived straight down the wall.

In this area, the temperature of the seawater is already quite high, about seventy to eighty degrees. Chu Chen can withstand this temperature with his water control ability.

Further down, the temperature reaches 100 degrees.

But 100 degrees is not the end point. The sea water at 100 degrees does not boil at all. The reason is very simple. The water pressure here is too high.

You know, 10 meters of water pressure is equivalent to an atmospheric pressure on Earth.

The depth of the sea here is more than three kilometers, which is equivalent to several hundred atmospheres.

Under such terrifying pressure, even if the temperature of the sea exceeds 1,000 degrees... it will not boil!

In fact, the seawater close to the submarine volcano can no longer be regarded as "¨ˇwater", but a supercritical fluid, which does not boil, but the temperature is extremely high.

That is to say, further down, the seawater temperature there can reach hundreds of degrees.

No wonder this high wall is 100 meters high.

The seawater inside seems to be circulating all the time.

.

Therefore, Chu Chen had to put on his armor here.

.

Chu Chen swam along the high wall, observing the situation above.

After observing for a period of time, Chu Chen found that the main focus of the sea people was above and around the prison.

Inside the high wall, there were no seamen paying attention, and there were not many fish.

After all, the temperature is so high.

If someone else wants to rob the prison, it must also be a way of storming and raising the cell.

No one will use Chu Chen's method to directly enter the lava!

It's too difficult.

If the girl Eve hadn't been there this time, without the kind of alloy that the girl Eve made that can isolate the temperature well, Chu Chen's method would not work at all.

In addition, this underwater prison has not been attacked by any sea creatures for more than a hundred years, so although there are many seamen guarding here, these seamen are actually a little lax.

.

After observing for some time in this way, Chu Chen came to the right under a beam, and with the help of the beam, he took out his armor.

This set of armor is not complicated to wear, and Chu Chen can complete it by himself.

It took a few minutes for Chu Chen to put on the armor.

However, no sea people have found him. After all, there are no sea people at all, and they have nothing to stare at the magma below.

Who wouldn't want to go into lava?

Their defense center is indeed around, not below.

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

After wearing it, Chu Chen checked the tightness with his mental power.

After checking, Chu Chen activated his stealth ability again.

With the armor, the stealth ability has been affected to a certain extent, and when it sinks, it will cause some movement in the water.

But it's not a big problem, because there are a lot of air bubbles in the high wall.

Chu Chen slowly descended.

After more than a minute, Chu Chen came to the undersea crater. Although it was a not very active volcano, it still spewed out some magma from time to time.

Then, Chu Chen entered the magma directly.

After having the experience of the volcano below the No. 4 industrial island, this time Chu Chen entered the magma and became more proficient.

PS: Let me tell you, in the next three to four days, the author will travel far away. In these three to four days, 3 chapters will be updated every day, each chapter will be about 3,000 words, um, the number of words in each chapter is slightly less, that’s it Well, it will be back to normal when I come back. .

Chapter 165

At the eyes of Chu Chen's armor, the alloy used is somewhat different. It is transparent and can be seen outside.

Of course, in magma, even if it is transparent, it is of little significance.
