After hearing Chen Zhifu's words, Ao Muyang laughed. The old man was a little interesting. In order to encourage himself to take risks, he actually drew a big cake like this for him.

So he smiled and said, "I am not interested in these treasures. Besides, according to national regulations, the treasures of shipwrecks in the sea belong to the state. As a probationary party member, can I pull out socialist wool and dig out the corners of communism?"

Chen Zhifu looked dull and asked, "Director Ao, are you making fun of me?"

Ao Muyang said seriously: "What amusing? I'm serious!"

Chen Zhifu immediately took a breath: "I am an old party member of the 50 years of party membership. I have never seen you a young man who is conscious. It is a blessing for the country and a blessing for the people."

Ao Muyang smiled and said, "Since that's the case, Professor Chen, can you ask me to help me? Go to the black chimney to find new creatures. Isn't this my life? Don't say anything wrong with treasures, just be sure there is a treasure. Then, can I find a life flower?"

He said this casually, mainly to find a polite refusal, but Chen Zhifu misunderstood.

Chen Zhifu said: "Do you think I was lying to you just now? What I said is true. The Jiangsu and Zhejiang areas have been rich since ancient times and are a golden area for maritime trade. In the early 19th century, in the early and mid-Jiaqing period of the Qing Dynasty, the southeast coastal areas we are going to now have frequent armed ship gang activities. At that time, pirates, Qing Shuji and maritime merchants performed countless stories on this sea. I will tell you in detail."

Ao Muyang smiled dryly and said, "No need?"

Chen Zhifu coughed seriously and said, "Why is it unnecessary? It's very necessary! Let me tell you about Cai Qian first. Cai Qian was the most famous of dozens of pirate leaders across the southeast coast at that time. In 1800, in the fifth year of Jiaqing, Cai Qian recruited Shui Ao and Fengwei gangs and the other pirates rose up. Two years later, on May 31, 1802, Cai Qian led hundreds of fishermen, boat owners and other people who had lost their livelihoods to Dadan Island and Erdan Island on Kinmen Island, killing the local defenders, burning and killing them on the island, and accumulating a large amount of treasures!"

"Some people are pirates, some are officials. Cai Qian's mortal enemy was Li Changgeng, the general of Dinghai at that time, and a senior general of the Qing Dynasty's waters. These two men, one bandit and one official, fought in the southeastern waters for more than ten years, and they can be said to be immortal."

"In the seventh year of Jiaqing, the court sent Li Changgeng to the Zhoushan area to supervise the construction of large ships, build 30 lightning ships, and more than 40 cannons to deal with Cai Qian's fleet. After several years of war, Cai Qian suffered repeated defeats, and in the end there were only more than 30 small warships, and disappeared on the sea with treasures that had been robbed for many years."

"After appearing on the sea again, it was in August 1809. Cai Qian lightly joined the battle with the Qing navy and was besieged by the Qing army. He was eventually outnumbered. He fired cannons and broke up his own ship. He died in the sea with his wife, children and more than 250 people. After his death, the Qing army tried his best to find the treasure he had plundered at that time. So where was the treasure?"

Chen Zhifu explained with an eloquence, then looked at Ao Muyang.

Ao Muyang spread his hands and said, "I don't know, Professor Chen, don't you think I know the information about this treasure, right?"

Chen Zhifu laughed in silence and said, "Of course you don't know, I don't know, but Lao Lu and his gang probably know that they have put in hard work on this. As long as you walk around with them often and they lack powerful divers, they will definitely have to ask you for help. Then you will get inside information?"

Ao Muyang understood that this old man was not giving up and was determined to convince himself to work for him.

He had no choice but to sigh, "Okay, Professor Chen, I'll listen to you, but I have something to say first, I can help you, but I won't risk getting close to the hot spring under the sea. That's too dangerous!"

Chen Zhifu smacked his lips and said, "In this way, I will arrange for my students to approach the hot spring first, and make sure there is no danger before you go there. Is it okay?"

Seeing his unwillingness to give up, Ao Muyang felt angry and said, "Professor Chen, you are taking risks with your student's life!"

Chen Zhifu said helplessly: "No, this is not a risk. Director Ao, you will know that the undersea hot spring is not that dangerous. And I will ask the students to send the undersea robot to collect information from the thermal spring. If there is danger, the undersea robot will feedback it."

Seeing that Ao Muyang was still unhappy, he sighed and said, "Fear comes from the unknown. Let's do this, Director Ao, anyway, we are still far from the target sea area. You come into the cabin with me first, and I will tell you about the undersea hot spring, which is our black chimney."

Undersea hot springs and black chimneys are both common names. The academic name of this oceanic landform is deep-sea hydrothermal vents. They are often hidden deep in the seabed. The principle is similar to natural hot springs on land: when seawater seeps downward along the coastal cracks, is heated by magma heat sources, and then flows upwards and erupts, it forms a deep-sea hydrothermal vent like a "chimney".

Ao Muyang roughly understood these things, and he said, "What is the temperature of the deep-sea hydrothermal heat sprayed out?"

Chen Zhifu said frankly: "The temperature is very high, about 200 degrees to 340 degrees."

Ao Muyang was about to clap his hands, but Chen Zhifu immediately said: "But this is the temperature at the center of the jet port. In fact, because the sea water has strong thermal conductivity, the temperature in the area around the jet port will drop sharply, and it will definitely not exceed fifty degrees. I will use the seabed robot to create a specific seabed temperature distribution map, which will not allow you to venture into the high-temperature area."

Together with the driver, there were four people and one dog. The oil was added during the speedboat and then they arrived at the target waters in the evening.

Ao Muyang had never been to this place, but he also knew that when Chen Zhifu talked about the horseshoe islands and reefs, he knew about this place.

As the name says, there are many small islands and reefs here, which are similar in shape, like horse hooves, which usually sink under the water and will only rise slightly from the sea when the tide is low in the day.

On the outside of Mati Island and Reef, a large ship broke down and was anchored, which was the marine scientific research ship led by Chen Zhifu. In addition, there were small boats parked near Mati Island and Reef in the distance. Chen Zhifu introduced him and said that Lao Lu and others were on those ships.

Listening to the introduction, Ao Muyang asked, "They can't spend the night on the boat at night, right?"

Chen Zhifu was stunned and said, "No."

Ao Muyang asked, "Then where are they going tonight? They still have big ships?"
