Because before entering the water, Luo Yuanhao and the photographer talked about the fish has a strong wisdom, so in addition to lighting to find the way, the photographer's lights are turned off, after all, the fish can't see the light, but can also feel the heat, which is affected.

A bottle of oxygen, to be precise, a bottle of compressed air, lasts for a maximum of an hour. They don't go underwater, so the consumption is relatively high, and it would be nice to be able to last 50 minutes.

And at a certain depth, the pressure has to be adjusted. Fortunately, their depth is very shallow, so you don't need to pay attention to this, the main thing is to keep an eye on the time, otherwise you will be in danger if you are not careful.

After about two minutes of diving, Luo Yuanhao was familiar with the way and found the three huge holes.

It's just that unlike before, this time there are a lot of fish, and a large number of them have human faces. Luo Yuanhao shone down with a lamp and found that the three holes were almost corroded through, and if they continued to corrode, they would become a large hole.

Luo Yuanhao didn't know if he was helping them to pierce the hole with a dagger at that time, in short, the current situation is very different from that time, many people are swimming around.

These fish are large and small, toothless and toothless, all kinds of strange shapes, dizzying.

On the top of his head, the fish raised by Fu Chengzi has broken a big hole, and some fish can be seen caught and eaten inside. It can be seen that these people face monster fish also eat fish.

When Luo Yuanhao saw this, he couldn't help but tighten his speargun.

Luo Yuanhao looked at the three holes again, and he found that these schools of fish originally lived in the mountains. How can there be schools of fish living in the mountains?

Groundwater?

Luo Yuanhao was taken aback, these strange fish actually came from groundwater? However, they have human faces, which is obviously not the credit of evolution, after all, it is not conducive to their hunting. The human face that formed what it is today is not so much an evolution as a degradation. Since there is no need for sharp teeth, the teeth degenerate and the snout degenerates.

These face monster fish are still fish predation methods, and their mouths are not prominent, so they are inconvenient to hunt in the end.

The dolphin, the most intelligent life in the known ocean, doesn't its mouth protrude a lot? Why are there so many fish in this area that have human faces?

Luo Yuanhao could feel that most of these strange fish had no ill will towards him, and many of them didn't even look at these two uninvited guests, swimming freely.

After the photographer took pictures for more than ten minutes, the catfish monster that Luo Yuanhao had seen last time and seemed to be wearing a grimace mask came again. Two came, and they were still squatting at the bottom of the water, observing Luo Yuanhao and the photographer. The four tentacles on the chin also catch small creatures in the water and send them to their mouths.

Luo Yuanhao suddenly remembered the big fish with a mouth full of teeth, and he was a little worried. However, he has a lot of weapons this time, and the big fish may not be as powerful as a shark, and it is absolutely impossible for him to hurt him in the slightest with spearguns and harpoons.

After more than ten minutes, there was no big fish, but Luo Yuanhao didn't dare to relax, he swam to the vicinity of the hole at a very slow speed, and then he turned on his headlamp and searched inside, it was not turbid, and there were a large number of fish, but some of these fish played with each other, some attacked each other, and some devoured each other.

These people blame the fish, with such high intelligence, but here they kill each other?

Luo Yuanhao shook his head, feeling incredulous. Fortunately, the fish are not big, almost no more than one meter five. The two outside are still observing the photographer, and those two should be considered the largest.

He reminded the photographer that he was going in. The photographer ignored him and kept taking pictures of the surrounding fish.

Luo Yuanhao had no choice but to continue to swim inside, and it was a straight passage for a long time, and the side wall of the hole was as if it was dug by fish, very rough, but dug very evenly.

Luo Yuanhao rubbed an arrow mark on the stone wall with a harpoon, although the passage was simple, he also had to avoid finding the way.

After moving forward for more than ten meters, it seemed to have come to a T-junction, and the water in front of him began to be turbulent, which seemed to confirm Luo Yuanhao's guess, this place is very similar to underground water. It was flowing rapidly from his front left to his front right, with a velocity of about three meters per second.

Luo Yuanhao knew that at this speed, once he was swept away by the current, he would never come back.

However, he has a harpoon and can climb forward along the rock wall, but the movement is more difficult, and it feels like he is climbing on his stomach.

He made a mark and observed, and he looked up and looked up, and suddenly, as if he saw a mirror reflection, it was five or six meters away.

Looking at the time, it was more than enough, he slowly climbed forward, and suddenly, he saw something reflective, like an ore like a night pearl.

After climbing a little further, he felt that the pulling force of the current suddenly decreased, and there was still water in front of him. He looked around and saw that he had entered a T-shaped junction again, and the current was almost unimpressed. He was afraid that he would get lost, so he made two more marks.

There are a lot of fish in this area, and many of them are human-faced monster fish. It didn't take long for Luo Yuanhao to see that the two terrifying catfish monsters actually swam over, and they came to Luo Yuanhao's side very friendly, as if to observe how he swam in the water.

One of them swam slightly faster, and Luo Yuanhao followed the catfish monster.

Immediately afterwards, Luo Yuanhao felt that the pressure around his body was shrinking, and his ears seemed to be ventilated, as if he was about to surface. This feeling made him very uneasy, but it only lasted for a few seconds, and he suddenly felt a chill on the top of his head, and as soon as he reached out his hand, he touched the air!

Luo Yuanhao immediately rushed out of the water, and found that this place was really air, and it was not pitch black, there were many things like night pearls emitting light. Luo Yuanhao found that there was actually ground here, so he immediately climbed up, turned on all the lights, and illuminated the surroundings at once.

"Oh my God!"

Luo Yuanhao's face suddenly changed greatly, and his expression couldn't help but reveal horror!

"This is an underwater ancient city!"

Luo Yuanhao looked around and saw that this was actually a city in the belly of the mountain, with various buildings. It's just that the architectural style is not Chinese-style, let alone Western-style, but similar to the Han Dynasty, or the architectural style of the ancient Roman period, rough, grandiose, and domineering.

Directly opposite, there is a wide staircase, flanked by towers, and in the middle there is a very shabby-looking palace, almost old and decayed.

Seeing this, it would be wrong if I didn't take out my phone to shoot again.

As soon as he took a film, he heard the water behind him "rattling", and it turned out that the two catfish monsters had rushed out of the water, supported by their two front paws, and actually walked on the rocky ground!

"Amphibians?" Luo Yuanhao's eyes couldn't help but widen, and he hurriedly took off his breathing and glasses. Because he knew that since the strange fish could be active here, it must be breathable air.

I took two puffs, and sure enough, it was fresh and smellless. It means that there are certain ventilation conditions here.

However, what surprised Luo Yuanhao was that behind these two catfish monsters, there was also a strange fish that also rushed up to the rock, and he also had a human face, and the terrible thing was that he actually walked upright, clumsy like a penguin......

The strange fish also holds sharp rocks on its front paws, which seem to be used as weapons.
