If it is just a simple large jellyfish, the light blue light emitted from its surface and the appearance of those tentacles like bright light strips are actually very beautiful.

But this is not the case in reality, because the energy fluctuations of Ziyue on this jellyfish are so familiar to Ji Yu.

In the pitch-black deep sea, when the first giant jellyfish appeared, it soon appeared one after another.

When Ji Yu controlled the olm to watch calmly, the final number of giant jellyfish that appeared was fixed at fifteen.

These fifteen giant jellyfish are like fifteen blue lights in the deep dark sea, they have been standing in the sea, and all of them approached the olm slowly.

It doesn't have any bones, and doesn't have any fast swimming skills. It only relies on its own umbrella-shaped head to rush towards the olm. To be honest, the speed is really not enough.

In Ji Yu's eyes, these giant jellyfish are just more intimidating, and so are their long and many tentacles.

The tentacles of jellyfish are poisonous. This must be common knowledge for modern people, right?

So Ji Yu is not polite at all to these large jellyfish that look big and scary.

He didn't wait for these jellyfish to attack him at all, instead he took the initiative to control the olm and rushed over.

At the same time, around the olm, the temperature of the sea water dropped rapidly.

The olm carries a huge vortex of water around it. When it dives towards the giant jellyfish, this vortex directly blows away the tentacles that these jellyfish want to entangle.

At the same time, when the olm carried this stream of water and rushed past the surrounding jellyfish, the surrounding seawater froze quickly.

You must know that this is five kilometers deep in the sea, and it may be the first part of human cognition to freeze on the bottom of the sea.

A strong cold current struck, and as the sea water froze, the tentacles of the giant jellyfish were instantly covered with a layer of hoarfrost.

At the same time as hoarfrost was produced on the tentacles of the jellyfish, the entire giant jellyfish seemed to be infected with a strong poison, and was quickly frozen into ice cubes.

If someone tested the temperature in the seawater at this time, they would definitely get a scary value.

Because at this moment, the temperature of the sea water here has dropped to around minus 120 degrees in an instant.

Fifteen giant jellyfish just turned into fifteen huge ice objects in an instant, and soon began to be squeezed by the pressure of the bottom of the sea and quickly float towards the sea surface.

Seeing this, Ji Yu stopped his movements.

Looking at the ice floes of giant jellyfish floating towards the sea, Ji Yu began to have new doubts.

That is, if these jellyfish have been staying in this abyss-like deep sea, how will they be polluted by Ziyue?

"The one who was polluted by the purple moon on the sea surface and then sneaked in here?"

Ji Yu murmured.

But after thinking about it, it felt wrong.

Because if these jellyfish are polluted on the sea surface, why do they gather in this trench?

And they're all the same size and pollution intensity?

Thinking of this, Ji Yu guessed a possibility in an instant.

That is, there is a boundary in this bottomless pitch-black trench.

If you think about it that way, everything makes sense.

Why can't the realm appear on the sea floor if it can appear on land? Or even underground?

If all this is true, then the situation of Blue Star is really very bad.

You know, the ocean on Blue Star occupies nearly 70% of the entire Blue Star.

Such a vast area, if there is a boundary.

Well, Ji-woo can already imagine how bad things are in the ocean.

However, if you think about it carefully, if there are really many ocean boundaries, will human ships on the waterways of the ocean be as easy to pass as they are today?

impossible?

In short, the possibility of boundaries appearing in the ocean is not low, but perhaps not many.

But no matter what kind of speculation it is, Ji Yu must now enter this trench to take a good look.

Therefore, without making any extra preparations, Ji Yu controlled the body of the olm to quickly move towards the trench where the jellyfish just rose.

At 6,000 meters, everything in the trench was as usual, but it was even darker and deeper.

At eight thousand meters, there was no movement in the trench, it was like a piece of stagnant water.

At 10,000 meters, Ji Yu finally dived into the deepest part of the seabed.

But here, what Ji Yu saw was another scene.

Because at this moment, although this area is still dark, the sea water is unexpectedly warm, and there are still many bubbles coming out of the seabed.

At the same time, Ji Yu also saw a submarine volcano erupting lava in the distance.

This submarine volcano is not big, but the billowing air waves and red magma erupted are still very eye-catching.

After being ejected from the seafloor, the magma cools quickly in contact with water and takes on the shape of black rock.

For the exaggerated scene in front of him, Ji Yu was also deeply moved by it.

However, while sighing, he did not forget the purpose of this trip.

However, it was a pity that Ji Yu swam back and forth and observed, but he didn't feel a trace of Ziyue's breath.

But the trench is huge after all, so Ji Yu was not discouraged immediately, but continued to search around.

Sparing the lava eruption area on the seabed, Ji Yu once again entered the dark and calm seabed.

Here, apart from the light emitted by the olm and the movement produced by swimming, there are no other larger creatures at all.

This kind of search is aimless and quite boring.

Half an hour later, Ji Yu still found nothing.

An hour later, there were still no living creatures on the surrounding seabed, and the entire trench seemed to be a dead zone except for the jellyfish.

However, just when Ji Yu felt that he might have thought too much this time and had already floated up.

Suddenly, at the moment when he floated up to a certain area, Ji Yu felt an inexplicable fluctuation.

Ji Yu couldn't tell what it felt like to fluctuate, but it really existed.

It wasn't Ziyue's fluctuation, but Ji Yu suddenly felt a burst of familiar energy the next moment after the fluctuation.

And it was at this moment that the olm under Ji Yu's control immediately raised his head and looked sideways.

In an instant, a trace of the familiar brilliance of the purple moon came into Ji Yu's eyes.

This ray of light is very weak, and with the fluctuation of the water flow, it also seems to have a sense of waves.

This brilliance sprinkled on the seabed close to 10,000 meters without any medium.

The area where the purple light exists is not large, but just by looking at it, Ji Yu knows that this sea area is a boundary area that no one knows about.

In this boundary, Ji Yu soon saw some large and weird sawtooth fish.

These fish wanted to enter the seabed, which belongs to Blue Star's dark deep sea, from the glorious realm, but the moment these sawtooth fish appeared on the 10,000-meter seabed of Blue Star, they were directly crushed by the terrifying pressure of the 10,000-meter seabed. .

That's right, it just exploded, like a balloon being squeezed from all around by someone, and then burst.

The scattered flesh and blood floated in the sea, and at the same time terrified the jagged fish that were wandering on the edge of the realm.

These fish are really not big, the biggest one is less than one meter long.

Although the appearance is a bit scary, and it is somewhat similar to a merman-eating fish, it still can't withstand the terrifying pressure under the 10,000-meter deep sea.

Obviously, the corresponding sea area or river where the boundary area is located is only a shallow water area.

And the shallow-water Ziyue fish on the opposite side couldn't adapt to the pressure of the deep sea at all, and had no chance to harm Blue Star.

Seeing this, Ji Yu is also quite interesting.

But while it was interesting, Ji Yu also saw that when the flesh and blood that was crushed by the pressure of the deep sea fell, there were many small things around the size of human thumbs and less than thumbs that were rushing to eat.

After looking carefully, Ji Yu discovered that there are many miniature jellyfish like water fleas around here.

These jellyfish swallowed the flesh and blood of these strange fish after they exploded, and quickly grew stronger.

In just a few tens of seconds, many palm-sized jellyfish with the breath of a purple moon appeared in front of Ji Yu's eyes.

There are only a dozen or so jellyfish, but Ji Yu is not soft on this.

The moment he wandered past, Ji Yu breathed out a icy breath at these little jellyfish, and then grabbed them with his claws, killing them all.

On the other side of the boundary, when those weird fish saw the olm emitting a clear light outside the boundary, they immediately seemed to be frightened.

They escaped quickly, and soon disappeared behind an illusory water curtain somewhere in the opposite realm.

Seeing this, Ji Yu was both puzzled and amused at the same time.

"Not bad? Compared with the Ziyue beings that Xiaolu met in the ruined city last time, these sawtooth fish still know how to compare the strength of the two sides?"

You know, in the ruined city of Ziyue last time, when the little deer unleashed its huge breath of life energy, the surrounding Ziyue creatures didn't care about their own strength at all, but swarmed towards the little deer.

Compared with those unknown Ziyue beings, the Ziyue jagged fish Ji Yu just saw are much smarter.

Looking at the realm with Ziyue's energy fluctuations in front of him, Ji Yu seemed a little hesitant.

The appearance of this realm is very strange, but at the same time it makes Ji Yu feel very curious.

Because he really wanted to know if entering the realm could allow him to enter the world where Ziyue was.

This curiosity was very strong, and Ji Yu also began to calculate the degree of danger.

Think about the school of fish just now, and think about the ability of the olm.

Well, although the opposite realm may be just a lake or river, and Ziyue's life is not strong, Ji Yu is afraid that the realm will appear suddenly and then disappear.

If that's the case, if Ji Yu goes to Ziyue World, how can he come back without this transfer station?

However, amidst this hesitation, Ji Yu thought of some particularity of the olm.

That is, the olm, the deer, and the oak tree are all life in the non-Ziyue world, and it seems that they will be repelled back to the blue star by the rules soon in the past.

Thinking about it this way, Ji Yu suddenly felt like dying.

This is not the first time for Ji Yu to commit suicide, once for the oak tree, once for the deer, and now it seems okay for the olm to do it again, right?

After all, the particularity and strength of the olm gave Ji Yu enough confidence.

So, in the end, Ji Yu's eyes fixed, and then he rushed into the realm suddenly.

The moment he entered the realm, Ji Yu only felt that his surroundings were filled with the radiation of Ziyue's energy.

But this kind of radiation is really weak for the olm. Being in the water, even Ziyue's river can still give the olm the power of water.

In the water, the olm is not afraid of the radiation of the purple moon, and it does not appear to be much different from that in the blue star.

In this way, Ji Yu immediately felt at ease.

At the same time, Ji Yu quickly turned his gaze to the center of this realm.

There, there is an illusory water curtain, from which the school of fish escaped just now.

Therefore, Ji Yu came directly to the water curtain, and hesitantly stretched out the claws of the olm through the water curtain.

Then, nothing happened, and Ji Yu's feedback from the opposite touch was still a piece of water.

And here, of course, Ji Yu will not have any hesitation.

The moment Ji Yu found out that the water curtain was harmless, he controlled the olm to slip in it in an instant.

The arrival of the olm is undoubtedly like a bomb falling into deep water.

The moment Ji Yu came to this water area, he immediately saw countless sawtooth fish and more aquatic creatures around him.

Don't give these guys a chance to attack the olm or escape.

In an instant, the entire water area froze quickly.

The sound of "clicking" was endless.

Except where Ji Yu left a channel leading to the water above his head, everything around him was frozen, and all aquatic life was frozen in a piece of solid ice.

Satisfied, Ji Yu also quickly swam towards the surface of the water.

The huge dragon head of the olm appeared for the first time under the illumination of Ziyue, and at this time, Ji Yu finally saw the surrounding environment clearly.

The area where the olm is located is a lake.

The lake is not big, and the whole looks like nearly ten thousand square meters.

Above the sky, a huge purple moon is shining brightly, and on both sides of the lake Jiyu is looking at a dense forest.

These woods grow crookedly, and the leaves are pitifully sparse.

Looking at the scene in front of him, Ji Yu felt as if he had entered the environment of a ghost story.

Moreover, the environment of this ghost story is quite similar, because on the other side of the lake, there are many low houses along the edge of the lake.

And outside these houses, there are twenty or thirty strange humanoid creatures with big heads gathered by the lake at this moment.

These creatures are less than one meter tall, and they are all bald. They are covered only by some worn cloth, and their exposed arms and legs are all dry, as if they have been hungry for a long time and are malnourished.

The olm's huge eyes were watching them, and they were watching the olm's terrifying gesture.

Face to face, both sides were stunned for a while.

In Ji Yu's eyes, these humanoid creatures have big eyes and look quite intelligent.

However, these guys are a little timid, because Ji Yu saw that some of these guys were trembling uncontrollably and wet their pants when they looked at him.

Then, I don't know which humanoid creature yelled first, and then the group of poor guys quickly ran towards the small wooden house on the bank crying.

Among them, some of them were obviously frightened and dumbfounded. Their whole body trembled and they couldn't exert any strength, and then they fell on the ground tremblingly, as if they had seen a monster and collapsed on the ground.
