Chapter 90

The sky gradually turned dark, and the crew members had finished their day's work. At night, the fishing boat would arrange for someone to stand watch.

Tonight, Ye Yuan decided to take the watch himself and instructed all the crew members to go and rest.

After all the crew members had gone to rest, Ye Yuan secretly slipped into the sea.

Ye Yuan found that the more he cultivated the "Water Control Technique," the more he could not leave the sea. In the seawater, he transformed into a fish, and the sea felt like his home, where he could move freely.

The night sea was also exceptionally beautiful, with various luminous creatures adorning the ocean, adding a touch of mystery.

Being in such an environment, one felt a bit excited and a bit nervous.

Ye Yuan continued to dive deeper. Before long, he reached a depth of 2,000 meters in the deep sea.

This area of the sea had almost never been visited by anyone, at least no one had ever reached the seabed.

The purpose of Ye Yuan's descent this time was to test his diving ability. He remembered that when he helped Xu Hang, he had only managed to dive to a depth of 2,000 meters before feeling resistance.

Continuing downward, the last time at 2,000 meters, he started to feel pressure. This time, with the improvement in his cultivation technique, he easily surpassed the 2,000-meter depth.

Continuing downward, when he reached a depth of 4,000 meters, he began to feel some discomfort. Ye Yuan knew that his current limit was 4,000 meters deep.

Without a doubt, Ye Yuan should be the first human on Earth to reach this depth without any equipment.

For other divers, no matter how skilled they were, they would not be able to withstand the pressure halfway down and could not continue.

At such a deep ocean, besides the pressure becoming a barrier for humans, there were also various dangerous deep-sea creatures.

At this depth, there was no light, it was a dark world, a layer of mist covering it. Without high-tech means, no one knew what was hidden below.

Ye Yuan continued to wander in this mysterious sea layer, seeing many strange creatures.

Many of them he did not recognize.

It was evident that human knowledge was still very limited.

On this ancient Earth, how many species lived here, modern technology could not clearly count.

In Ye Yuan's perception, a sperm whale swam over from a distance.

This sperm whale was over twenty meters long, like a giant submarine.

The sperm whale had a very peculiar appearance, with a large head and a smaller lower jaw, only the lower jaw had teeth. From a distance, it looked like a giant tadpole swimming towards you.

Many introductions say that most whales are gentle, but a small part of them are very fierce, such as orcas.

The sperm whale is one of them. Due to its large size, it is terrifying in a fight.

Because of its large size and fierce nature, it is called a sea monster by the older generation of fishermen.

The sperm whale's favorite food is giant squid.

The two are natural enemies. Once they meet, they will definitely fight until one of them wins, and it is hard to separate them.

Ye Yuan had seen videos of sperm whales fighting giant squids.

One of the giant squids used its tentacles to block the sperm whale's blowhole, causing the sperm whale to suffocate and die.

However, most of the time, the sperm whale would be the winner when it encountered a giant squid.

The fight between a sperm whale and a giant squid is very spectacular. Both would leap out of the water during the fight.

It was like two small mountains chasing each other in the sea.

However, the giant squid is not without a way to escape. Most squids would use the ink they spray to confuse the sperm whale and then escape when they couldn't fight it.

Ye Yuan did not want to anger this giant. He quickly moved away.

The sperm whale's mouth, when opened, was several meters wide, and a small boat could be swallowed in one bite.

Ye Yuan was not confident that his water needle could deal with it, and storing it in his spatial ring was out of the question. He had already tried it before, and if the weight exceeded his ability, he could not store it.

Looking at the size of the sperm whale, Ye Yuan believed he did not have the ability to store this giant in his spatial ring.

Although Ye Yuan was envious of the points this creature could provide, he believed that if he could really convert it into points, it would not be few. However, compared to his life, points were less important.

He might be swallowed in one bite before he even got close.

Keeping a safe distance from the sperm whale, Ye Yuan did not want to stay here any longer and quickly swam upward.

"Hmm?"

While swimming back to the fishing boat, Ye Yuan noticed a white stone floating up and down in the water not far away.

Ye Yuan swam over and grabbed the stone, which didn't look very special.

The stone was white, somewhat like the appearance of a reef, not very heavy, but Ye Yuan was surprised to see such a stone here, as stones in the sea are usually on the seabed and do not float in the water like this.

Ye Yuan was about to throw the stone away when he suddenly thought of an item in his memory.

He hadn't thought of it before, but seeing the sperm whale and then finding this stone nearby made him connect the dots.

Looking at the stone in his hand, the more he looked, the more he felt it was the legendary ambergris.

Although Ye Yuan was a student at the Marine University, he had never seen ambergris, only read about it in books.

Ambergris, also known as sperm whale amber, is a solid, waxy, flammable substance that is gray or black.

Ambergris is actually the dried secretion from the intestines of sperm whales. Some sperm whales vomit it out, some excrete it through their intestines, and only a few keep it inside.

When it is discharged into the sea, it is initially dark in color, but under the influence of seawater, it gradually turns gray, light gray, and finally white.

Historically, it has been mainly used as a fixative in perfumes.

It is mainly composed of ambrox and a series of cholestane alcohols.

Ambrox is the main component of ambergris. It does not have the fragrance of ambergris itself, but it is closely related to the fragrance and function of ambergris.

Ambergris is a clear and elegant animal fragrance, the highest quality in animal fragrances.

Its fragrance is similar to the beauty of musk, slightly earthy, somewhat like seaweed, wood, and moss, with a special sweetness and an extremely long-lasting base note, a very complex fragrance combination.

Although its intensity is not strong, it is subtle and smooth, with a fragrance that lasts 20 to 30 times longer than musk, up to several months, making it the best fixative.

It can blend various fragrances well, making the fragrance soft and long-lasting.

Ambergris is often used in a 3% tincture.

When used with musk and civet, it enhances the fragrance.

In China, ambergris is not only used as a fixative but also as a traditional Chinese medicine.

It is mainly used for: promoting qi and blood circulation, dispersing nodules and relieving pain, promoting urination and diuresis. It is very effective in treating coughing, shortness of breath, qi stagnation, abdominal pain, and urinary tract infections.
