Mariins's words made Li Du confused. He entered the water in his diving glass and then surfaced. Why were he praised? Why were Sophie and the others criticized?

Brother Wolf approached him and asked in a low voice: "Boss, don't you pay attention to the oxygen cylinder reading?"

They undergo deep diving training, and of course they will bring oxygen cylinders into the water. Generally speaking, the air in the cylinders can make people stay in the water for half an hour to forty minutes.

Mariins told them at first that during diving, you should always pay attention to the numbers on the diving computer watch. Under normal circumstances, the numbers it displays are usually 200.

Li Du looked at his oxygen cylinder computer table calmly. The number on it was only 42. He looked at the other three people, and the number was lower than 50.

According to the requirements, if the number on the computer table is as low as 50, you have to tell your companion, coach, to be ready to float up and leave the ocean, which is a dangerous number.

Obviously, the oxygen cylinders that Mariins gave them were tampered with, but after they got into the water, they were too excited and didn't pay attention to this.

Li Du didn't pay attention, but he was lucky. Water was in the mirror before, and he took the initiative to float up, making Mariins think that he had discovered the problem of oxygen cylinders like Brother Wolf.

In fact, only Wolf Brother was paying attention to this among the four...

Mariins and his assistant kept setting traps for them, which were common difficulties encountered during diving, so Mariins let them perceive them in advance.

While experiencing these problems and water difficulties, Malins also teaches them to enhance their diving skills.

Deep diving is the beginning of diving, and snorkeling is just a stepping stone. Li Du’s previous behavior of fishing for black gold abalone was not considered diving, which was called making a fuss in the water.

After systematic learning, they began to get involved in freediving, and in this way, a new world slowly opened the door to them.

The underwater world is so gorgeous, with a large number of marine life and plants growing lushly. Before free diving, they can also contact life in the ocean through the clear sea water.

But it seemed like standing outside the glass of the aquarium, they could only look at the underwater creatures in the giant glass tank, and they could participate when they were free diving.

Mariins showed them his power. He did not use any equipment and could go deep into the water for hundreds of meters, and then swim in the water like a fish.

However, at this depth, the ocean is no longer visible. Li Du can see through the flying insects, but no one else can see anything.

In fact, diving in the ocean is enough to dive twenty meters. This deep underwater world is the most gorgeous and prosperous. The sunlight is not penetrating enough, the light is not good, and the ocean ecosystem is not very exciting.

Diving mainly depends on experience. This is similar to a sharpshooter. The shooting posture is like that. To become a sharpshooter, you rely on bullets to feed it and you need to keep shooting.

Similarly, there are only a few diving postures and skills. To become a diving expert, you need to dive more, increase your time in the water, pay attention to safety and stay healthy. Over time, the stronger your diving ability will be.

Of course, to become a world-class diving athlete like David Mariins, you have to rely on extraordinary talents and physique.

Li Du and the others will dive to a depth of twenty meters at most, and this ordinary person can do it, without having talent and physique beyond ordinary people.

I spent five days following Mariins to learn about free diving and continued to go deep into the sea to fish for black gold abalone, so that Li Du and others would be more confident.

Mariins told them that freediving is a group extreme activity. When you go into the water, someone must follow you. If you have any problems, you will be able to get first aid immediately. This is double insurance.

This time when they returned to Jindao, they wanted to do a big fight, so they were planning to rent a boat for a long time.

Most of the boats on Jindao are yachts for tourism, and the rental price is relatively expensive.

After Li Du and the others discussed, they wanted to rent a fishing boat, which was cheap and was enough for them to use. Anyway, they only went out of the near sea and not the far sea.

"Let's go and see how much a new ship costs. If it's right, maybe we can buy a new ship because we have a fishing license, so we may come every year in the future." Hans said.

Li Du felt it made sense and decided to go to the ship company first. If there is a suitable new ship, then buy one.

Australia is a maritime country with many ship manufacturers. Among them, there is a ship company called Behemoth Ocean Heavy Industry in Melbourne, which produces very famous ships.

Hans found their salesperson online. After contacting him, the other party learned that they were in Melbourne and took the initiative to drive over to pick them up for a visit.

The salesman who arrived was named Rooney Cade, an energetic middle-aged man with red hair, got off the car and shook hands with them, and then began to talk about yachts and ships.

They went directly to the factory area of ​​Giant Ocean Heavy Industry on the suburb coast. The company has multiple production lines and assembly workshops here, and also display platforms.

The ships produced by Giant Marine Heavy Industry are diverse, including leisure boats, business communication boats, racing boats, fishing boats, private boats, public security patrol boats, and port supervision boats.

In addition, there are fire boats, salvage boats, fishing boats, fishing boats, operation boats, crew boats, adventure boats, cable boats, search and rescue boats, etc. In short, their ships cover almost all kinds of ships.

On the way, Rooney was very enthusiastic about introducing them one by one and asking them what they needed.

Li Du said: "We are preparing to fish for black gold abalone, so we think ordinary cruise ships are enough, and there is no need for very luxurious yachts."

Rooney nodded and said, "Yes, I understand this. Leisure boats, ordinary working boats and fishing boats are relatively suitable for your job, and they are of high quality and low price."

Li Du asked, "Then do you have any good recommendations?"

Because the other party is so enthusiastic about them, Li Du doesn't mind giving him a business, but it shouldn't be a big business, and he doesn't want to buy very expensive yachts.

Rooney touched his nose and said, "I already have an idea, but I think it's useless for me to introduce you now. You have to visit them and get in close contact. If you run into a suitable ship, your heart will tell you that it belongs to you."

After driving to the factory, they went to a dock first.

There is a beautiful big ship here preparing to go into the sea. The hull is super long, maybe three or four layers, the shape curve is extremely smooth, the overall white, the bow deck is wide, and the stern is equipped with a helicopter apron. Judging from the appearance alone, Li Du and others were shocked.

"We know that the rich people around the world are tired of driving yachts to conventional seas such as the Caribbean or the Mediterranean. They have an adventurous heart and want to go to more extreme places."
