(New book, ask the bigwigs to collect and recommend!) ）

The Arctic Ocean, the coldest ocean in the world, can see large and small ice Xiaoice floating everywhere on the sea, and I don't know how many years ago these icebergs were formed?!

It is said that some icebergs were formed even back millions or millions of years!

These ices are veritable 10,000-year-old ice!

It's just that if you don't have as many magical abilities as in the novel, I'm afraid it will be disappointing.

Cheng Fan dived into the sea, the temperature in the sea is higher than the sea surface, but it is cold all year round, and there are environmental factors such as polar day and polar night, resulting in fewer types and quantities of marine life.

Because it was polar night outside, and there were many ice floes and icebergs floating on the sea, the light in the sea was extremely dim and almost none, even with Cheng Fan's eyesight, he couldn't see far in the water.

He looked at the compass on his wrist and knew that if he crossed a certain area, the direction of the needle would be reversed, and the direction he was going would change to south, and the path he had come from would become north.

The water is dark, and the further down you dive, the darker it gets, and the fewer creatures you see.

Cheng Fan had never known about the Arctic Ocean before, and he didn't know that this sea was not only the coldest ocean on earth, but also the shallowest and smallest ocean.

The average depth of the sea is just over a kilometer, and the deepest depth is only more than 5,000 meters, which is far less than that of the oceans that move thousands and can reach a maximum depth of 10,000 meters.

But the sea is the sea, not the lakes and rivers, and no one knows what kind of monsters are hidden under the boundless water, especially this ancient ocean.

As the dive goes deeper, the greater the water pressure Cheng Fan bears, and according to the mechanical formula, it can be easily concluded that when the density and gravity coefficient are constant, the liquid pressure is related to the depth of the liquid.

Cheng Fan is now at a position close to 600 meters under the sea, and the huge water pressure is on him, but he can withstand it alive.

He dived so deep, naturally not because he was full, nor because he wanted to see the scenery of the deep sea, but to exercise his body.

Using the high-pressure underwater environment to temper your body and movement speed in order to provide more security for the future, this is a bit like the gravity room cultivation of Son Goku and Vegeta in Dragon Ball.

As early as the previous two-month sea trip, he had already done this, exercising within a range of sea depth, and then challenging the next depth when he was able to move freely.

The innate quality of this monster's body is really much higher than the weak body of a human, and he has been able to move freely at a depth of more than 600 meters after more than two months of training from more than 300 meters at the beginning.

The journey was long, and Cheng Fan himself didn't realize that after he passed through a region, the direction of the compass had been reversed, no longer pointing north, but facing south, proving that he was already heading south.

People often confuse the geomagnetic north and south poles with the geographical north and south poles, but in fact, the two do not coincide a little, but have a certain deviation angle, so in the Arctic region, the compass may not necessarily face north.

Cheng Fan is not in the mood to care about these now, he had an accident when he challenged the depth of 800 meters, this accident was not that the water pressure was too high and unbearable, but that his activities provoked a tentacle monster living at the bottom of the sea.

This thing is bigger than a hill, nearly 100 meters long, transparent and colorless, with a head like an umbrella-shaped jellyfish, no eyes, and it is impossible to see where its mouth is from the outside.

Cheng Fan dodged back and forth between the eight tentacles, these eight tentacles are not only long, but also fast, and extremely soft and tough, Cheng Fan tried to cut with his claws and bite with his mouth, but the outer layer of this thing is smeared with a layer of extremely sticky and slippery mucus, which is not slippery on his hands, whether it is bitten with his mouth or cut with his claws, it is difficult to damage a bit.

Moreover, there are many disgusting little suckers growing on this tentacle, which look like many naked eyes without eyeballs open and closed, and each of them has a strong suction, if a dense phobia sees one, it is guaranteed to faint in fright.

Is there such a big monster living under the Arctic Ocean? Did you touch it yourself?

Cheng Fan didn't know whether to sigh that he was lucky or unlucky, he wanted to escape from here many times, but the successive attacks of the eight long tentacles, like a thick wall, always blocked his way, so that he couldn't escape.

This jellyfish-like tentacle monster has no intelligence, but its predatory instincts are enough to make it quite terrifying.

The attack trajectory of each tentacle is not chaotic, but cooperates with each other, and this cooperation is not to grab the prey immediately, but to gradually compress the prey's activity space, and finally capture it.

Cheng Fan has already discovered this after being attacked by tentacles many times, every time he dodges a tentacle, another one will force him to swim in one direction, if he doesn't go, he will be caught, and if he goes, he will be compressed into the activity space.

His current situation seems to be quenching his thirst, and if he doesn't find a way to escape, he will be caught and preyed on sooner or later.

But if he wants to escape, he has to shake those eight tentacles, but if he can deal with the tentacles, why should he escape?

It's a circular puzzle!

Speaking of which, it will attract the attention of the tentacle monster, and it is also due to the fact that this guy has lived too well during this time of travel, and occasionally adds food, causing his body to grow a lot.

I remember that before he left the island, he was only more than two meters tall and three meters long, but now he is more than four meters tall, and he is more than six meters long from head to tail.

The space to move and dodge is getting smaller and smaller, and there are three tentacles caught in a net, and there is a surge of water behind him, Cheng Fan doesn't need to look back, and he knows that there must be tentacles flanking back and forth.

He swam back and forth between the tentacles, not a fish, but tried his best to swim more flexibly than a fish, his body slid forward and backward in the water, rushed left and right, and did all kinds of difficult movements, if this thing went to participate in the Olympic synchronized swimming or something, he would definitely win the championship.

Unfortunately, he still couldn't escape, and a tentacle appeared above his head, blocking his escape path.

Cheng Fan is like a mouse teased by a cat, and it is only a matter of time before he is caught.

Escaped many times like this, Cheng Fan was surrounded by five tentacles, three tentacles attacked, he swam upwards and avoided seven, but was accidentally pulled by the last one.

At the moment when the tentacles grabbed the hind legs, those disgusting suction cups immediately sucked on Cheng Fan's legs, and before Cheng Fan struggled, a sharp pain immediately came from his legs, and something kept pouring into Cheng Fan's body.

Cheng Fan felt numb all over his body and passed out on his tentacles.

The sharp teeth on the tentacle suction cup bit through Cheng Fan's scales, and injected the venom that can paralyze the animal's body, digest and dissolve it into Cheng Fan's body.

The tentacle monster rolled Cheng Fan's body with a tentacle and sent it to the bottom of the umbrella-shaped body, where a large mouth without teeth opened, and then threw Cheng Fan in, and closed it again, and the tentacle monster itself also stopped moving, and it seemed that nothing had ever happened in this ancient sea.
