Wu Zhi, who returned to the inside of the small crack at the beginning, slowly flapped the fins on his body, and he was thinking about the secret contained in this mysterious giant wall after recovering some physical strength from the escape and wild swimming.

Although I couldn't figure out the truth about my transformation into a fish from Shiroyu, I still got a lot of useful information.

First, at the very bottom of this deep sea, there must be a highly intelligent creature with the ability to think, such as the mysterious white fish. If I didn't guess wrong, the reason why he turned into a fish and came to this deep sea was probably the work of these creatures.

Second, from the message transmitted by the white fish, the words "the place of the test of the king of fish" appeared. From the series of events that have just occurred, it is not difficult to deduce that this so-called place of trial refers to the giant wall of rock. And the meaning of the existence of this place is most likely to satisfy some kind of terrible plan of high-IQ creatures in the deep sea!

The third is the rock wall itself. The creatures of the deep that lie dormant in the pits or caverns are so calm that their anomalous behavior has nothing to do with the word "trial"!

"Even if they don't kill each other if they are of different races, it's impossible to keep squatting in the hole after so long, at least they have to come out to hunt!"

Looking down at the still extremely quiet pit below, Wu Zhi's heart was full of doubts, and he wanted to figure out all these doubts immediately.

It's just a pity that with his current weak physique, he is really not qualified to go down to the bottom of the deep sea to explore and study.

"Or ...... Are these potholes themselves hidden? ”

Looking at one pothole after another, Wu Zhi secretly guessed in his heart.

After such a line of thought appeared, he did not hesitate so much, and set off to swim towards the long darkness ahead.

He felt that he had to go back to the pit of the giant claw shrimp and crab to study it carefully, even if he lay all the black plants in the pit to see how its internal structure differed from ordinary rock caves!

As for why he didn't grab a pit under him nearby, except that Wu Zhi was not absolutely sure of his own strength now, and he could kill the unknown creatures in the pit one hundred percent. Another reason is that after two high-intensity upstream and downstream movements, his stomach is a little hungry, and his physical strength is not particularly sufficient.

So, to be on the safe side, he chose to swim through the long rock interior and return to the pit that was already his own.

If you have the chance, you can catch a big skull fish or something over there to fill your stomach, and that's the best!

Unlike the nervous caution when he first came over, Wu Zhi, who knew the internal structure of the rock giant wall, swam very fast this time, even if there were dense black pits under him, he did not have too much fear.

Because he already knew that this place was only the top of the so-called trial, and the more dangerous and terrifying creatures almost all existed in the lower strata.

In other words, he has the confidence that he will not encounter a fatal crisis in such a place!

In fact, Wu Zhi had this instinct, even if he swam swaggering inside the rocks further down, those giant deep-sea creatures would not burrow out of their burrows to prey on him.

Of course, after all, he didn't have the guts to appear in the inner space of the lower rocks!

The long journey took place in the frighteningly quiet waters, and it was not until a sealed rock wall appeared in the darkness beyond his vision that Wu Zhi slowed down and swam forward to watch.

Judging from the time, he should have almost reached the location of the giant pincer shrimp and crab pit, but the rock wall without any exit in front of him really existed. At first glance, it looks very unscientific.

"This should be the end, why didn't there appear that small crack of more than ten meters at the beginning?"

After observing the closed rock wall for a while, Wu Zhi discovered the problem.

According to the analysis of the height and length of the cracks on both sides of the rock wall, the crack he came in from the deep sea at the beginning should have been naturally formed, not designed for the "Fish King Trial".

In other words, there was only one exit on the design of the rock giant wall, and the reason why there was that small crack more than one meter high was purely formed by chance!

After clearing his thoughts, Wu Zhi began to swim horizontally along the enclosed rock wall.

As the rock wall spread little by little, finally, the field of view of 12 meters gradually contracted and narrowed, and a hole leading to the deep sea appeared little by little, replacing the closed rock wall.

The familiar location of the pothole, the familiar rock section, here, is the small crack where the giant claw shrimp and crab were found at the beginning!

"My judgment was correct, and I came to this place again!"

Wu Zhi, who had been advancing inside the oppressive rock for a long time, immediately swam over happily, rushed out of the crack directly, and temporarily left the inside of the mysterious rock giant wall, without returning to the familiar pit to observe the situation at the first time.

Although the field of vision is already very limited, staying inside the rock, where the average height is only more than two meters, can cause discomfort in the body.

It wasn't until I returned to the open sea and swam freely beside the rock wall that the discomfort gradually disappeared.

At the end of the day, to be a fish is to live in open water!

Leaving the depths of the oppressive rock cracks, Wu Zhi could more or less feel how uncomfortable those fish were trapped in a narrow tank.

"Okay, the discomfort in my head that I was so depressed that I fainted is finally gone!"

A few minutes later, Wu Zhi slapped the fish's tail and re-entered the crack in the rock giant wall, and slowly swam to the pit where the giant pincer shrimp and crab had been staying.

Although he saw the familiar skull fish when he was wandering and relaxing outside the crack, Wu Zhi had no idea of preying on them for the time being.

The most important thing at the moment is to find out if there is anything special inside the pothole. As for filling your stomach, you can do it at any time.

"Huh? How did this pit suddenly have so many black plants? I remember when I set out to find the carcasses of giant pincer shrimp and crabs, didn't I have already cleaned up all the plants at the entrance of the cave? ”

When he came to the pit, Wu Zhi found that the hole that should have been clear as far as the eye could see was covered by dense black plants. This seems very strange, after all, I have the impression that this disgusting black plant should not grow so fast!

"Do you mean ......?"

Wu Zhi cautiously approached the mouth of the hole, the muscles on his body tensed slightly, and he thought of a very bloody plot.

That is, in the few hours he was gone, the crater was once again occupied by a certain deep-sea creature!
