The pitbull is still very loyal. When he saw Ao Muyang and others appear, he wanted to get up and shout.

The general pressed his head down with his front paws, and the pit bull hummed and said that I saw a stranger. The general told him with his actions, no, you didn't see it.

Ao Muyang went up and dragged the general away. If Lao Lu's side saw him playing other people's watchdog here, there would be another conflict.

The pit bull was tied up by Lao Lu and his gang for a long time. The whole spring was spent in loneliness. Now when he met the general, it was thunder and earth-fire. Ao Muyang thought it was the general who forced him, but later found out that it was the pit bull seducing the general.

Because after he dragged the general away, the Pitbull whimpered in the corridor all night, with a very resentful tone. King Kong came out and yelled at it several times but it was useless.

With Ao Muyang coming, the scientific research team is about to start work.

The first thing that was put into the water were two submarine robots, that is, two small ATVs. They were traveling under the sea and driven by radio signals on the ship to control them to take photos and take samples on the seabed.

Watching the car wandering under the sea from the screen, Ao Muyang asked, "Isn't it enough to use this kind of car to take samples? There is no need to dive at all, right?"

An expert named Gu Dawei shook his head and said, "No, the sampling procedures are complicated, and robots cannot do such multi-programming work. In addition, their use requires a high environmental requirement. If the terrain is too complex, they cannot move forward."

After the robot was traveling underwater, some coefficients were passed back to the computer.

There are five black chimneys under the sea, which are considered a hydrothermal zone. The diameter of the black chimney is not large, the largest one is only thirty centimeters, and the others are mostly ten to twenty centimeters.

Black smoke continued to spray out from the mouth of the ground. This was a mineral-containing hydrothermal hydrocarbon, with a central temperature of 350 degrees Celsius. If the diver dared to get close, it would turn into braised meat in minutes.

After the extremely high temperature ore-containing hydrothermal fluid is sprayed out, it mixes with the surrounding sea water and quickly produces precipitation and turns into "black smoke". The black smoke continues to spray up, looking spectacular.

The robot collected sea water from multiple locations and returned to the ship, and then the students took down the sampling tube for testing.

Ao Muyang followed and saw that the precipitates sprayed from the local black chimneys were mainly composed of pyrite, pyrite, sphalerite and copper iron sulfide. The surrounding water was corrosive and toxic because it contained sulfur and mercury, which was very dangerous.

The robot also collected a message, that is, the acidity in the core area of ​​the black chimney is also extremely high, with a ph of about 2, which is a strong acid.

In such an environment, life is still developing vigorously. Judging from the image data collected by the robot, there are many bubbles around the gushing liquid. Shen Zhifu came over and said, "Take a microbial development for the liquid. Use various culture media. Now, there are microorganisms that use the chemical energy in dissolved salt for primary production."

The two doctoral students following him nodded and wrote down instructions in their notebooks.

Shen Zhifu gave them some instructions, and then explained to Ao Muyang and the other two: "We cannot see it with our naked eyes, but there are many microorganisms in this place, which at the same time form the first link of the food chain and provide food for primary consumers. Therefore, studying the black chimney will help us understand the initial life form of the earth."

Ao Muyang nodded to show his understanding. Yu Xinbo muttered in a low voice behind him: "However, this has nothing to do with us."

Chen Zhifu didn't hear him clearly and asked, "What? Teacher Yu, what did you say?"

Zheng Songlin hurriedly said, "It's nothing, Professor Chen, don't we rely on robots to make a 3D thermometer in the sea area of ​​black chimney? Did it be made?"

Chen Zhifu smiled and said, "Don't worry, it hasn't been done yet, but it's almost done. The robot below is drawing a 3D thermometer."

Lao Lu and his group boarded the boat and headed for the waters of Mati Island and Reef again. Chen Zhifu went up enthusiastically and asked, "Lao Lu, are you coming back for lunch?"

"We won't be back, we bring compressed biscuits and military rations." Lao Lu said, patting a box on the boat.

Near noon, a 3D thermometer was created.

Chen Zhifu did not deceive them. The black chimney sea area was not that dangerous. Although the temperature was as high as 350 degrees Celsius when the hydrothermal was sprayed, it expanded from the center to the surroundings, and the water temperature dropped exponentially, and the sea water outside the range of two meters dropped to 50 degrees Celsius.

The 3D temperature meter is well-made, with different colors indicating temperature differences. Each iconic temperature band is clearly depicted, and the seabed terrain displayed above is very accurate.

After lunch, Ao Muyang began to go into the water.

The scientific research ship is very professional. Not only is it equipped with a complete range of laboratory equipment and tools, but it is also complete with diving tools, including gas cylinders, airbags, facial mirrors, underwater respirators, back plates, lead-pressure belts, fins, and diving caps. These conventional equipment are naturally available.

In addition, they also carry sonar equipment when they go into the water. Ao Muyang doesn't know these things, so Zheng Songlin and Yu Xinbo have a lot of contact, so he explained it to him.

Multi-beam, side sonar, shallow strata and deep-sea GPS are all very professional tools for underwater detection and scanning. This is the first time Ao Muyang has come into contact with him, which makes him a little embarrassed. He is the leader of the diving team.

However, Zheng Songlin and Yu Xinbo did not underestimate him. Yesterday, Ao Muyang helped the two stand up and dared to fight head-on with Lao Lu and his gang, which has won their respect.

Black chimneys are also called deep-sea hot springs, because they are located in extremely deep ocean waters. The earliest black chimneys discovered are located in a trench.

The black chimney they were going to explore was shallow, with a water depth of only more than 280 meters, and professional divers could perform face-to-face work in-depth diving.

Ao Muyang first went into the water himself. According to the plan, he wanted to dive into the safe area around the black chimney, then smash the ground hook and tie the rope, so that the people behind him could dive down the rope.

After entering the water, he first adapted to the water temperature, then exposed the water surface and stretched out his thumb to show that everything was normal. The deep diving suit was very bulky and it was not easy to complete these simple tasks.

After receiving his signal, Zheng Songlin and the others returned with the ok gesture, and then Ao Muyang officially dived.

He glanced around and looked down and found that the sea here was quite abundant, including hairtail, sea bass, and pomfrets. They were all fish, big or small, still or moving.
