Chapter 647

Qin Shiou was very happy to see Billy. After all, this was his partner and gave him a Porsche 918.

At this meeting, Qin Shiou felt that Billy's mental outlook was much better. His golden hair was crisp, his face was ruddy and energetic, his eyes became sharp, and his muscles were bulging like a small volcano.

"I don't have to greet you. Your mental and physical condition must be very good recently." Qin Shiou said with satisfaction.

Billy smiled and did a bodybuilding move: "thanks to you and Winnie, I finally lost my way and stopped indulging in wine and sex. Recently, I have been shuttling between the gym and the diving boat. I really feel that I am in good condition. "

Qin Shiou asked him to sit down and asked, "have you found true love?"

Billy shrugged and said, "no, not yet, but I'm not in a hurry. I believe that if God wants me to meet true love, he will bring the girl to me. All I have to do now is wait patiently."

"Good. I admire your attitude now. But what if God wants to see you remain single? "

"No, God will not be so cruel. I trust him so much. He will give me a satisfactory result."

Chatting casually, Qin Shiou left Billy in the villa for a simple lunch. He couldn't drink because he had to dive in the afternoon.

After lunch, Qin Shiou and Billy went to Chenbao lake. When Tang Ji saw the two together, he was surprised and asked, "is it such a coincidence? Billy said the old friend to visit was Qin? "

"It seems that your relationship with Qin is not general." Billy said with a smile that Qin Shiou wouldn't let them expose their cooperative relationship outside, so he changed the topic.

With this relationship, the later things will be much easier. Tang Ji prepared a diving suit for Qin Shiou, and handed over other questions to Billy.

When he learned that Qin Shiou had never dived before, Billy was surprised and said, "do you never go to the water to see the situation of the fishing ground?"

Qin Shiou secretly said that I can control every corner of the fishing ground without entering the water. Of course, he thought about it in his heart. He said, "of course not. I have so many fishermen. If I want to work in the sea myself, why should I hire them?"

Thinking about Qin Shiou's laziness, Billy nodded and said, "yes, it's really your attitude towards life."

He gave a brief introduction to Qin Shi Gu. Shallow water diving suit was divided into two types: wet type and dry type. Wet type is more commonly used, generally made of foam synthetic rubber material, and the thickness is between 3mm and 10mm.

The main function of wet diving suit is to ensure that the infiltrated cold water is isolated by clothes and will not penetrate again. This isolation by inactive bubbles can prevent the loss of body heat. The fit wet diving suit can reduce the flow and exchange of internal and external water as much as possible.

However, in cold zone waters, dry diving suits are often used. This kind of diving suit has many kinds of materials. Foam rubber, synthetic rubber and nylon material are commonly used.

The diving suit prepared by Tang Ji for Qin Shiou is a dry diving suit. It is much higher than the wet diving suit. It has special waterproof zippers and other accessories, such as dry diving inflatable exhaust device.

Because the dry diving suit needs to be inflated and vented, it needs special training when wearing it. This is the reason why Tang Ji refused to let Qin Shiou go into the water. Underwater is not better than land. If something happens, it will kill people every second!

For a diving master like Billy, I don't think the situation is so serious, but some things must be made clear: "if you want to go into the water, you have to listen to me, everything, and look at my gestures."

Qin Shiou nodded and said he would be good.

Seeing this, Billy nodded with satisfaction and continued: "first, I'll teach you to use the diving suit inflation and deflation system. You see, because the air must be injected and discharged into the dry diving suit to maintain neutral balance, there is a pipeline in the diving suit from the medium pressure interface of the first stage of the regulator to the inflation valve..."

Tang Ji tried the water temperature. The surface water temperature of Chenbao Lake in the early summer afternoon was more than ten degrees. This temperature was more suitable for divers, so he had a little confidence in Qin Shiou's launching.

Billy also explained to Qin Shiou that the main function of the diving suit is to maintain the body temperature. Therefore, if the water temperature is higher than 20 degrees, you don't have to wear it. If the water temperature is lower than 20 degrees, you need to wear a dry diving suit.

After explaining clearly, Billy helped Qin Shiou put on his gray and blue diving suit and get ready to enter the water. Then he himself wore a set of bright silver diving suit. He looked very smart, just like the legendary golden haired little white dragon.

Qin Shiou threw his mouth and said, "you really don't forget to be handsome at any time. Although I'm not a diving expert, I also know to keep hidden underwater. Do you wear this exciting color diving suit to deliberately stimulate the creatures in the water?"

Billy smiled, "all you know is appearances. For small creatures, the more conspicuous they are in the water, the more dangerous they are. But for big guys like us, it's safer to wear bright diving suits, which can remind some scheming guys and let them notice the strength gap between us so that they can go away as soon as possible. "

With that, Billy put on his oxygen mask and dived from the boat in a backward position.

A long air pipe stretches down from the ship. One end of the air pipe is connected with an oxygen mask, and the other end is connected to the bow oxygen generator to provide them with a continuous flow of oxygen. This is a common oxygen supply method for shallow water diving, which can minimize the pressure of divers.

Qin Shiou took a deep breath of oxygen and held it in his lungs as Billy taught him. Then he leaned back and fell into the water.

Blocked by a diving suit, Qin Shiou didn't feel the coolness of the lake. He sank a few meters under his head and feet in the water, then his feet shook quickly, used his fins to provide power, and followed Billy deeper.

Previously, Qin Shiou estimated that the water depth in this depression was only 20 or 30 meters. In fact, he was too casual. From the pressure gauge in his diving clothes, when they were close to the bottom of the lake, the water depth had exceeded 50 meters!

Sixty meters is the limit of wearing this simple diving suit. They walk on the edge of the limit.

Recently, there are many ships coming and going in this water area. There are people diving and machines coming down to explore. Therefore, there is no fish around, and all the fish are scared away.

Nevertheless, Qin Shiou still feels very interesting.

He turned on his head lamp. A shining beam lit up the dim bottom of the lake. Billy swam over from behind and gestured to ask him how he was doing.

When diving, the biggest obstacle is not the water pressure and cold water temperature, but the psychological state. Underwater light is very weak, surrounded by vast cold water, which will cause great psychological pressure and make people feel helpless, lonely and afraid, which will do great harm to divers.

Qin Shiou is most used to this because he has the heart of sea god. He never feels lonely and afraid in the water. He is like a king in the water. This is his territory. Why does he feel lonely and afraid in his own territory?
