Led by the Black Bull and the Tornado, Li Du swam in.

Soon, a huge corpse of a sea beast appeared in the light in the cold ice water.

Its body is about four meters long, its body is round, and a long horn extends from its mouth, of course, this is actually its teeth.

The narwhal appears!

Of course, this is the corpse of a narwhal. It is well preserved in ice water and has no traces of rot on the surface. However, Li Du looked carefully and could see that there were wounds on its body surface, and the rot began along the wound.

He swam over and touched the narwhal's teeth, which was what he had been looking for.

Now his location is just the opening of the invisible cemetery. The ice cave is very big. No wonder the old man Xiaopi said that it is very spectacular.

As we walked around and deeper into it, more and more narwhals appeared. We looked up and saw that there were also corpses of giant beasts above our heads. Some of the corpses rotted and revealed their white skeletons, some of which were frozen and well preserved.

Looking at these giant beasts, Li Du took a deep breath and a string of bubbles emerged beside him.

Because of the comparison between the giant beast, his body became very small and his bubbles were smaller.

I don’t know how many narwhals are here, but wherever he sees it, there are all such giant beasts, and there are hundreds or thousands of them, it’s okay anyway.

Unfortunately, the times were wrong. If Li Du discovered so many narwhal corpses in the Middle Ages, he would have quickly become rich and rich.

Superstition in the Middle Ages prevailed, and narwhal's whale teeth were said to have the effects of curing diseases, preventing diseases and detoxifying. People used narwhal's teeth to make goblets, tea cups and bowls, and believed that after pouring the toxic liquid, it would "black foam will appear and then the toxicity will disappear."

The emperors and popes at that time regarded whale teeth as treasures. Although the princes and nobles who had unicorn horns were constantly suffering sudden and inexplicable deaths, this horn still enjoyed the reputation of antidotes, and its price in the market has always remained unchanged.

Four centuries ago, Charles V of the Holy Roman Empire gave two unicorn horns to Marlefer, Bayreut, France, to pay the debt equivalent to $1 million today.

Of course, to this day, no one believes that narwhal teeth have these effects. Now its value lies in sculpture and scientific research.

A narwhal can penetrate two thousand meters deep underwater. Its teeth are never affected by changes in water pressure and can remain normal under various pressures.

This performance is valuable to modern marine science, because the deep sea has always been a world that humans cannot understand, and humans still lack sufficiently effective super-dive equipment.

The growth of narwhal teeth can provide some clues to the research of these diving equipment, so many scientific research institutions are very interested in the tooth of narwhal.

But Li Du knew that there was a better way to make money. In history, the Danish king Friedley III collected the most unicorn horns. He used unicorn horns to make a throne, which was considered a miracle in Europe.

For a long time, this throne has been used for the coronation of the Danish king, and its legs, handrails and bases are made of narwhal teeth.

The narwhal's teeth are not titanium alloys. It has been scarred for hundreds of years of use and competition, and was eventually destroyed in a palace coup.

The throne left behind a photo information. Li Du wanted to recreate one for sale to the Danish royal family. He believed that the royal family would be very interested in this thing.

Nowadays, narwhals are an endangered species, and major governments strictly prohibit the trading of whale teeth. Fishermen in some areas of the Arctic can hunt narwhals for consumption and whale oil extraction according to traditional conditions, but whale teeth will be confiscated by the government.

The whale teeth here come from whale corpses. As long as strong proof is given, they can flow into the market.

After visiting the ice cave, he surfaced.

Although there is no claustrophobia, Li Du felt that it was still very unhappy to stay in such a deep-sea ice cave. He was particularly depressed. He always felt panic in his heart, as if the ice cave could close or collapse at any time!

Note the specific coordinates, it will be much easier to come here next time.

Li Du took everyone back to the boat as usual. When she saw everyone's expressions, Sophie knew the result and said, "Have you found that cemetery? How many narwhal corpses are there?"

Brother Wolf showed her the photos taken by the underwater camera, and Sophie raised her eyebrows and showed a surprised expression: "God, so many? This is simply a miracle of nature!"

"If you witness it with your own eyes, you will feel even more shocked." Li Du sighed.

Sophie looked at these photos silently, looking at them very seriously.

After a long time, she said, "Actually, there is no need to destroy this cemetery. God will definitely not be happy... Well, telling you that God is useless and you are not afraid of him. In short, I think it is a bad thing to destroy a natural miracle like this."

Li Du said: "It's nothing, right? We don't hunt narwhals, we just use their bodies to make the best use of them. If we don't use them, wouldn't they be wasted?"

Sophie looked at him sincerely and said, "Dear, listen to me, if we destroy this cemetery, where will the narwhals die in the future? Also, you will flow whale teeth into the market. Maybe you are legal, but there are always people with illegal whale teeth in their hands. What should they do if they mix illegal whale teeth into it? This is to help the evildoer!"

Listening to her persuasion, Li Du said helplessly: "Then why are we going to the North Pole? You are willing to come to the North Pole with me to find this cemetery."

Sophie said weakly: "I thought this so-called cemetery had only one or several groups of narwhals, at most twenty or thirty."

Li Du said: "Let me think about it. It's so boring if we don't get anything, how boring would it be?"

"Who said there was no gain?" Sophie laughed, "We have been to the North Pole, the South Pole, the North Pole, we have all been to it. Isn't this an amazing experience?"

The Hammerhead Shark hit the way south, and suddenly broke down after leaving the glacier.

There are the chief engineer and the technical director of the entire ship's machinery, power and electrical equipment.

He went to check the situation and came back with a report sheet and said helplessly: "The transformer responsible for powering the propeller is burned. We have to replace it with a new one, otherwise we will not be able to leave."

Li Du said: "Then change it, there is a backup transformer on the ship, right?"

The chief engineer's smile was bitter: "Sorry, sir, we have no stock. The ship was originally docked for maintenance, and some spare parts were used up before. One of the purposes of this maintenance is to supplement spare parts."

Li Du was stunned: "What should I do? Our ship can't just stop here, right? Is there no other way?"

The chief engineer spread his hands and said, "Unless a tugboat dragged us away, or someone brought us a new propeller current transformer, we were unfortunately left to stay here."

Sophie said coldly from the side: "You said, could this be the undead of the narwhal that was causing trouble?"
