After searching for nearly 20 minutes, Bai Xiaobei stops in a remote place. It is almost less than 100 meters deep below. Li Momo can look for the treasure below.

Bai Xiaobei raised his head and made an OK gesture: "Ziyi, you can play in this area with foam and pocket bag first. This side is less than 100 meters deep, and the beach below is very beautiful!"

Li Momo can't dive in the deep sea. Bai Xiaobei is worried about the accident of Doudou. After all, it's easy to happen when you have a good time.

"Oh, oh, diving!" Pocket directly rushed down, Bai Xiaobei quickly went up to embrace the pocket, and stopped his behavior.

"What are you doing, brother?" he asked innocently

"Don't leave Ziyi and Mo Mo's sight, you know? Otherwise, I will send you back immediately, and you will not be able to go anywhere in the future

If you don't make it clear, you'll be lost in the sea by then. It's bad.

Doudou quickly points to the cerebellar bag and says: "pocket knows, pocket doesn't run around, pocket goes down to look for shells!"

After Wu Ziyi and Li Momo also came down, Bai Xiaobei loosened his pocket and said, "it's very beautiful down here. Ziyi, you should pay attention to protect the foam."

"I see. By the way, where are you going?"

Listening to Bai Xiaobei's tone, Wu Ziyi knew where Bai Xiaobei was going and asked curiously.

"Go to prepare seafood. We will have seafood barbecue and collect some seafood. When we go back, we will send them back. Few people in our village have ever eaten seafood."

Qingyan village is far away from the sea. Bai Xiaobei wants to take some seafood back. Of course, this is just by-pass. His main purpose is to find treasure.

Wu Ziyi and Li Momo quickly shifted their attention and dived down. Bai Xiaobei threatened his pocket again. Doudou nodded repeatedly to show that he understood, and then he went down.

Bai Xiaobei, who has already reached the foundation level, is very fast, several times faster than the last time. Even the shark can't reach anything.

"Well? Shark? "

In the distance, when it is less than a few hundred meters into the sea bottom, a body is long, thick and round, in a flow line, gradually tapering backward, with a slender tail base, and a forked or crescent shaped caudal fin. There are obvious ridges on both sides of the caudal peduncle, and a row of small fins behind the dorsal and gluteal fins. It has the shape of a torpedo, and its cross section is slightly circular. The shape of the shark is also very strange. Its whole body is streamlined. The breastplate extending along the head seems to be a unique balance board that can adjust the water flow.

Bai Xiaobei is surprised to see a shark here. Suddenly he feels wrong. Isn't this tuna? Where is a shark!

Tuna! Bai Xiaobei Yixi, the two meter long tuna is extremely fast, but it is difficult to get away from Bai Xiaobei's speed. In a flash, he comes to the tuna's side.

Sure enough, this is a tuna. Its tail is half moon, which enables it to sprint forward quickly in the sea. It has strong muscles and crescent shaped caudal fin, with gradually expanding scales on the shoulder. The breastplate is dark on the back and silvery on the ventral side. It usually has iridescent rays and stripes. Another feature is that there is a developed vascular network under the belly, which can be used as a body temperature regulating device for long-distance slow swimming. Li Momo sent tuna to him before, and it is the most expensive black tuna.

This one, obviously, is black tuna, also known as bluefin.

"Good luck to find this fish here?" Bai Xiaobei, however, has heard that tuna are usually found in the sea area with higher temperature. He didn't expect to encounter it here, so he reached out to catch it.

Bluefin tuna, the largest species of tuna, is also known as black fin tuna. The body is short and strong, conical and slender, with forked caudal fins; the color from the bottom to the side of the body is bright, the upper body is dark blue, the fins are dark dark, the small fins are yellowish, and the protuberant ridge of caudal stalk is black. This species is characterized by its scaly body, rather large mouth, small eyes, short pectoral fin, and less than the center of the first dorsal fin. The body length is generally 1-3 meters, the larger is more than 3 meters, and the weight is more than 700 kg. This one is obviously not the largest.

Perceiving Bai Xiaobei's approach, bluefin tuna was obviously frightened, and its speed suddenly accelerated. However, it fell into Bai Xiaobei's eyes and could not escape at all. He slapped him directly on the head.

The huge tuna was shot to death, and his body was still twitching and shaking. Bai Xiaobei grabbed the tuna and put it into the storage bag.

"Have a good mouth!" Bai Xiaobei is very happy. When he goes back, he invites everyone to eat roast seafood. It is estimated that many people have never eaten this roast tuna.

He continued to swim towards the sea. After more than ten minutes, he felt that he had reached nearly 10000 meters deep and swam directly to the bottom of the sea.

The more you swim down, the colder the water is, the less fish you can see. Because the pressure on the bottom of the sea is too strong, there are not many living things that can adapt to the deep sea floor.

Moreover, it is difficult to hunt below. Just when Bai Xiaobei felt the pressure, he saw the bottom of the sea. If his eyesight had not been immune to most of the darkness, he could not see clearly below.One by one glittering fish, this is the survival and evolution of fish 10000 meters below the sea floor, because it is dark here, they all rely on this to attract fish and then eat them.

Different from the place where Liu Sansheng was born last time, it is obviously colder here. The fish of ten thousand meters in the deep sea are adapted to the environment, and their physiological functions have changed a lot. These changes are reflected in the muscles and bones of deep-sea fish. Due to the great pressure of the deep sea environment, the bones of fish become very thin; they are easy to bend; the muscle tissue becomes particularly flexible; and the fibrous tissue becomes extremely fine.

What's more interesting is that the fish skin becomes just a very thin membrane, which can make the physiological tissues in the fish full of water and maintain the balance of internal and external pressure. That's why deep-sea fish can't be squashed under such great pressure.

Secondly, in order to adapt to the dark environment of the deep sea, the fish living in the deep sea have to identify the same species in the extremely dim light, look for mates and forage, which requires them to have the ability to emit light.

Different fish emit different lights, which can transmit information to each other in the same fish, and lure other fish to sacrifice, or to get rid of predators. Therefore, luminescence is one of the important means for deep-sea fish to survive.

Bai Xiaobei's appearance obviously frightened a flat fish near him and swam away at a very slow speed.

"Is the fish delicious?" Bai Xiaobei thought about it for a moment, but he didn't do it at last. After all, even if people rely on the detector to scan the fish in the deep sea, they can't be sure whether there is poison. In case there is something harmful to the human body, the gain is not worth the loss.

A slender shadow came from afar. Bai Xiaobei had already shot it with one hand. The shadow was only four or five meters away. With a palm of spiritual power, it was madly struggling and ran away. Bai Xiaobei felt as if he had hit a sponge. He immediately understood that the creatures on the sea floor should not be underestimated.

This is a snake like creature. It is estimated that in order to adapt to the bottom of the sea, it has become a little different. Bai Xiaobei did not pursue him, but went down to look for treasure.

There are a lot of differences with the last 10000 meter sea floor. There are few creatures, few shells, crustaceans, sea cucumbers, starfish and so on, and the temperature is relatively cold.

After swimming for a while, they were attacked by several kinds of deep-sea creatures. However, each one had a strong ability to protect his life. Bai Xiaobei's success also made them not die directly.

Soon, Bai Xiaobei felt that the temperature here had increased a little. He was surprised and looked around. He seemed to see that there were more and more creatures in the dark sea bottom. However, he understood that the place was getting deeper and deeper. How could the temperature be hot?

Many land-based creatures also appeared. When I saw a submarine volcano in baixiaobei, I suddenly understood that it was suitable for survival here!

There are a lot of soft creatures in the sea floor, such as some colorful giant starfish, bony seabed stones, strange fish. Bai Xiaobei even saw the lantern fish that he was hunting. He was hiding there, quietly relying on his own light to attract fish. Unfortunately, the fish nearby clearly understood that it was not easy to be provoked and walked around.

"The stone is hard and a little red, but it's impure, and it's very difficult to refine it."

Bai Xiaobei is a little disappointed to see the most stones and minerals here. After all, it is 10000 meters of sea floor. The pressure is enough to crush steel. These stones can exist, and they are very hard.

He met some huge seashells. Every one of them was huge in size and had amazing defense. Bai Xiaobei immediately killed the seashells and put them into the storage bag together. He went back to study whether there were any good pearl treasures in them.

After searching for half an hour, the materials needed were not found, but shellfish were found. Just as Bai Xiaobei was about to leave, he suddenly saw dozens of giant vines crossed together.

"What is this?" Bai Xiaobei is curious. You know, the giant vine looks like a creature, but if it is also a creature, is it too big? And there are sharp spines on these vines.

With the existence of the last giant sea snake, Bai Xiaobei was on the alert, picked up a stone, injected spiritual power, and directly hit it.

The resistance and pressure at the bottom of the sea made this stone have little strength after it hit. However, in Bai Xiaobei's eyes, the huge vines are indeed creatures, stretching out like an octopus and disappearing here in one jump.

"I grass, is this octopus?" When he came to the bottom of the sea, he was the biggest living creature except the giant sea snake last time. He left very fast. When he drew back, he disappeared in his sight.

"The bottom of the sea is not safe, or go back to look after the pocket, can't let her run around."

This guy obviously has no malice. If he is vicious, Bai Xiaobei is sure to leave and even kill him. But if he is a pocket boy, he will be in trouble.

I quickly swam to the top. Although the sea floor is said to be rich in treasure, there is obviously no treasure in this area. It seems that the deeper the place, the more treasure there is, the more dangerous the deeper the place.

It's better to clean up the treasure of the sunken ship! Bai Xiaobei murmurmured in his heart and swam to the top.www.novelhold.com , the fastest update of the webnovel!
