Wang Xijia thought that the underwater home of the gills was just a small natural cave, like a hermit crab, but he didn't expect it to be quite big. There were some fluorescent creatures swimming around in the cave, and Wang Xijia only recognized the alarm jellyfish, and the others did not know.

There were two pillars at the doorway, and beside them leaned a few harpoons, which were supposed to be used for decoration. There are some stone tables and chairs in the cave, which look very delicately carved, and I don't know if the gills moved them from the shore or carved them themselves.

There was no furnishings in the cave except for the tables and chairs.

"Sometimes it's raining up there, so we're here to hide. Snake said. It's strange that the snake can talk in the water, just like it can talk on the shore. Ordinary people will burst out of a string of bubbles when they speak in the water, and the words they say are incomprehensible to Ulu Ulu, probably because the snake breathes by its gills in the water, so it does not affect the work of the articulatory organs.

"Hey, hey, can you hear me?" Wang Xijia's diving suit did not have a sound amplification device, so he was afraid that the snake would not be able to hear it.

"Can you hear me?" Snake asked. Sound can also travel in water, as long as you can make it, you can hear it.

"How are you sleeping in the water?" Wang Xika was curious.

No, just like that, Ah Snake struck in a backstroke position and lay in the water, like a fish. Due to buoyancy, there is also a feeling of weightlessness in the ocean. You can sleep in any position you want, and the sea water envelops you from all sides, supporting you in perfect ergonomics. You don't have to worry about falling pillows or wrinkling your sheets, and you can sleep much better in the sea than on land.

The best thing about living in the water is that you don't have to worry about natural disasters such as earthquakes and mudslides, and you don't have to worry about mosquito bites.

Gills have no natural predators in the sea, and there is nothing from blue whales to great white sharks that are not afraid of them.

A snake swam out of the hole, grabbed two tuna and handed one to Wang Xika. Wang Xika naturally couldn't eat it while wearing a diving suit, so he could only watch Snake eat the fish.

"Let's go, let's go up?" Seeing that Wang Xika couldn't do anything in the water, Ah Snake suggested that he should go back to the shore. Wang Xijia agreed.

In the past, Wang Xijia only knew that the gills could live in the water, but he didn't know how to live.

"Can you give us electricity?" said Snake, still thinking about getting electricity in the water.

Wang Xijia thought for a while, the risk of laying wires on the seabed is too high, and any fish will bite off the wires, and there will be leakage accidents. All Snake wants is brightness, and he has to find a way to arrange a lighting device for him that won't leak.

"Yes, I'll get you something that shines. Wang Xika said.

The lighting equipment that Wang Xijia came up with was very simple, a large waterproof flashlight. The battery can be used for 24 hours and can be recharged when it runs out. A snake used it for a few days to say that it was not bad, but it was too troublesome to charge.

"I can't help it, I can only do it to this extent now. The main thing is that it's too troublesome to get wires underwater, and if you're on the shore, I can provide you with whatever you want. Wang Xika said.

"It's better to be on the shore, who wants to live underwater in the future?" sighed Snake.

Indeed, if humans had been living underwater, they would never have learned to use fire. If you can't use fire, you can't develop technology. Attracted by new technologies, it is inevitable that people living in the sea will go to land, and perhaps this is why there will be no more gills in later generations.

But the technological explosion brought about by Wang Xijia's crossing may break this rule, allowing the cheeks to retain their amphibious characteristics.

Wang Xika and Ah Snake discussed their plans for a long trip, saying that they planned to build a ship to explore the ocean.

Ah Snake said, "Why are you bothering to do that? Why don't you just sit with me when the time comes?"

Wang Xijia thought about it and felt that it was still unreliable, because he couldn't rely on food to get water like a snake, and if he couldn't replenish fresh water in the ocean, he would hang up, and if he had a boat, he could cook on the boat and eat cooked food.

"Where did you get those tables, chairs, and pillars in your house?" Wang Xika has been puzzled. Why do you need tables and chairs in such a buoyant place in the water?

"Ah, they were all picked up from the water. To the west, there is a large area of city on the ocean floor, similar to the city on the shore. I thought the tables were pretty good, so I got them to decorate. Snake said.

Under the sea to the west, a large city?Wang Xijia suddenly thought of the legend of Atlantis.

Legend has it that Atlantis had a highly developed civilization, which was first recorded in Plato's Dialogues, which states that the continent was destroyed by a prehistoric flood.

Later generations also said that Atlantis may have been affected by a huge earthquake and the subsequent tsunami, which caused the entire continent to be submerged in the sea.

Some underwater pyramids have been found at the bottom of Gibraltar, suspected to be the remains of Atlantis.

"I'll get you a camera then, can you take a picture of that city and show me?" Wang Xika has always been fascinated by the legend of Atlantis, hoping to see what the city is all about.

"Okay, I just don't know how to use your stuff, if it's too complicated. Snake said.

"No, it's not complicated at all, you just have to flip the switch then. By the way, do you know how that undersea city fell?" asked Wang Xijia. The Snake clan has lived in the sea for a long time, and may know some legends about that continent.

"Oh, I heard from the old people in the village that the city was our hometown, and it is said that our people also lived on the land from the beginning, and built the city. Then I don't know how, the city exploded, and then we lived half the time in the sea and half on the shore - anyway, there is something that everyone in the tribe has heard, but who knows if it's true or not?" said Snake nonchalantly.

"What about the sea people who live at the bottom of the sea and never go ashore, and did they also fall from the land with you?" Wang Xika was very interested in this legend.

"Ah, the Sea People? That's not like us, they've always lived underwater, they were underwater before the city exploded, and they're still here. They are water monkeys. When it came to "Sea Man", Ah Snake looked disdainful. It is not difficult to think that the range of activities of the cheeks and the sea people is close, and it is inevitable that there will be some bumps, territorial disputes or something.

"What does that sea man look like, can you show me when the time comes?" asked Wang Xijia.

"It's not good, the sea people don't get along well. I went to shoot them and I didn't know if they would hit me. Snake said.

"Can't you beat them in the water?" Wang Xika always thought that the gills were the overlords in the water, and even whales and sharks had to retreat when they touched the gills.

"It should be fine in the shallows, take them to the surface and they die, they can't breathe on the shore. But not in the depths, not as fast as they swim. The seaman swam as fast as lightning. The main reason is that their feet are different from ours, they are fish tails, and you basically stop eating when you throw their tails, and you can't prevent them. Snake said.

"What about their upper bodies, do they have hands?" Wang Xika asked. The snake's feet are like those of an amphibian, with webbed in the middle, and this structure naturally swims faster than the average human, but certainly not as fast as a fish. It's like a frog, a duck, or something like a fined animal that doesn't swim as fast as a fish.

"The upper body of the sea people is similar to ours, and they have two hands about the same as us, but they also have two fins, so they have four hands. They don't have eyes, but they have a great sense of smell and hearing, and they can smell you from afar, so I don't know if I'll be found when I photograph them. Snake said.

The upper body is a human and the lower body is a fish's tail. Isn't this the legendary mermaid? Wang Xika has heard a lot of legends about mermaids, such as the little mermaid who is willing to turn into a mute in order to see the prince, and the kraken who will bewitch the sailors with his singing.

But this creature only existed in mythological stories in later generations, and was not seen with one's own eyes. There is also no mention in mythology that fish-people have no eyes.

Wang Xijia's curiosity was completely aroused. What kind of world is this? There are hairy people, werewolves, vampires, gills, and fishmen!

He suddenly remembered that the Vatican City State Codex kept by the Vatican God had recorded such a story: There were four generations of human beings in the world. The first generation of humans were giants. Giants do not come from our world, but from the heavens. The giants later became extinct due to starvation. The second generation of human beings, also from heaven, was destroyed by a great fire. The third generation of humans is the ape-man, and this generation of humans became extinct because of cannibalism. Later, a fourth generation of humans appeared, this generation of human beings who were in the "sun and water" stage, and became extinct because of the great waves of the flood.

Similar legends appear in the records of the Mayan civilization. If this account is true, then is the giant Zach and Jack hairy people? Are the second generation of people from the "heavens" aliens? In the end, because the spaceship exploded and caught fire, it hung up, so it was "destroyed by a huge fire". As for the third generation of ape-men who were destroyed by cannibalism, this is very understandable, isn't this the human beings of later generations? So, who is the fourth generation of human beings in the stage of "sun and water"?

There are even more legends about the "water monkey", and different civilizations in Asia, Europe, America, and Africa have recorded this primate that lives in the water.

In the scientific community, it is also said that in the history of human evolution, there is not only the current human race, but also Neanderthals, Zhoukoudian people, Yuanmou people and other human races that were later extinct. It is also said that at a certain stage of human evolution, they once lived in the ocean for a long time, so they took off the thick hair on their bodies.

Different legends, myths, and scientific speculations are intertwined. Wang Xijia only felt his brain buzzing, as if he had discovered something remarkable, but he couldn't figure it out.

"You must take pictures of the city in the water and the people of the sea to show me when the time comes!" Wang Xika said to Ah Snake.

"I tried my best. Snake scratched his head and said.
