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

Seeing each other this time, Qin Shiou felt that Billy's mental outlook was much better, his golden hair was crisp and neat, his face was ruddy and full of vitality, his eyes became sharp, and his muscles were bulging, like a small volcano.

"I don't have to greet you, your mental state and physical condition have definitely been fine lately." Qin Shiou said with satisfaction.

Billy smiled and made a bodybuilding gesture, "Thanks to you and Winnie, I've finally figured out that I'm no longer addicted to alcohol." I've been shuttling between the gym and the dive boat lately and I do feel like I'm in good shape. ”

Qin Shiou invited him to sit down and asked, "Then 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 send that girl to me, all I have to do now is be patient." ”

"Very good, I admire your current mentality. What if God wants to see you single all the time, though? ”

"No, God won't be so cruel, I trust him so much, he will give me a satisfactory result."

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

After lunch, Qin Shiou and Billy arrived at Shenbao Lake. When Tang Ji saw the two together, he was surprised and asked, "It's such a coincidence?" The old friend Billy said he was going to visit was Qin? ”

"It seems that your relationship with Qin is not ordinary." Billy laughed and said that Qin Shiou didn't let them expose the cooperative relationship between the two sides outside, so he changed the topic.

With this layer of relationship. The rest of the matter was much easier, Tang Ji prepared a set of diving suits for Qin Shiou. Leave the rest to Billy.

Knowing that Qin Shiou had never dived before, Billy was quite surprised and said, "Don't you never go to the water to see the situation in the fishing ground?" ”

Qin Shiou secretly said that Lao Tzu can control every corner of the fishing ground without entering the water. Of course, he thought about this, and he said, "Of course I don't look at it, I have so many fishermen, if I want to go to the sea to work myself, what should I hire them to do?" ”

Thinking about Qin Shiou's laziness, Billy nodded and said, "Also, this is really your attitude towards life." ”

He gave Qin Shiou a brief introduction, shallow water diving suits are divided into wet and dry two, wet is more commonly used. It is generally made of foam synthetic rubber and has a thickness of between 3mm and 10mm.

The main function of the wetsuit is to ensure that the cold water that penetrates into the suit is isolated by the suit and will not penetrate out again, this isolation by inactive bubbles can prevent the loss of body heat, and the fitting wetsuit can reduce the flow exchange of internal and external water as much as possible.

However, in cold waters, dry wetsuits are more commonly used. There are many materials for this wetsuit, but the most common ones are foam synthetic rubber, synthetic rubber and nylon.

The wetsuit that Tang Ji prepared for Qin Shiou was a dry wetsuit, which was much higher than the wet suit and had special waterproof zippers and other accessories on it. For example, dry diving inflatable exhaust devices.

Because the dry wetsuit needs to be inflated and exhausted, it must be specially trained when wearing it, which is the reason why Tang Ji refused to let Qin Shiou go into the water before, and the water is not as good as the land. If something happens, it's going to kill you in seconds!

For a master diver like Billy, I don't think the situation is so serious. But something has to be made clear: "If you're going to go into the water, you'll have to listen to me." Listen to me, look at my gestures to act. ”

Qin Shiou nodded. Said that he would be obedient.

Seeing this, Billy nodded in satisfaction and continued: "First teach you how to use the wetsuit inflation and deflation system, you see, because the air must be injected and discharged from the dry suit to maintain neutral balance, there is a line in the wetsuit that connects from the medium pressure connection of the first stage of the regulator to the inflation valve......"

Tang Ji tried the water temperature, and the surface water temperature of Shenbao Lake in the early summer afternoon was more than ten degrees, which was more suitable for divers, so that he had some confidence in Qin Shiou's launch.

Billy also explained to Qin Shiou that the main function of the wetsuit is to maintain the body temperature, so you don't need to wear it if the water temperature is higher than 20 degrees, and if the water temperature is below 10 degrees, you need to wear a dry diving suit.

After explaining clearly, Billy helped Qin Shiou put on a gray-blue diving suit and got on the boat to prepare to enter the water, and then he himself put on a bright silver diving suit, looking extremely powerful, just like the legendary golden retriever little white dragon.

Qin Shiou pursed his lips and said, "You really don't forget to be handsome at any time, although I am not a diving master, but I also know that I try to stay as hidden as possible underwater, are you wearing this exciting color diving suit to deliberately stimulate the creatures in the water?" ”

Billy laughed, "What you know is just appearances, for small creatures, the more visible they are in the water, the more dangerous they are." But for big guys like us, it's safer to wear brightly colored wetsuits, which can remind some of the bad guys to notice the difference in strength between us and get out of here sooner. ”

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

A long trachea runs down from the boat, with an oxygen mask attached to one end and an oxygen concentrator at the bow of the boat, providing them with a constant supply of oxygen, a common method of oxygen supply in shallow water diving, which minimizes the stress on the diver.

Qin Shiou took a deep breath of oxygen and held it in his lungs as Billy taught, then leaned back, and fell into the water at once.

Blocked by a wetsuit, Qin Shiou didn't feel the coolness of the lake, he sank a few meters deep in the water under his head and feet, and then his feet shook quickly, and he used his flippers to provide power, and followed Billy to dive deeper.

Previously, Qin Shiou estimated that the water depth of this depression was only twenty or thirty meters, in fact, he was too casual, judging from the pressure gauge of the diving suit, when they approached the bottom of the lake, the water depth was already more than 50 meters!

Sixty meters is the limit of wearing this improvised wetsuit, and they walk on the edge of the limit.

Recently, there have been a lot of boats coming and going in this water, and there are people diving and organic qì coming down to investigate, so there is not a single fish around, and all the fish are scared away.

Despite this, Qin Shiou still felt very interesting.

He turned on the headlamp he was wearing, and a shining pillar of light illuminated the dim bottom of the lake, and Billy swam up from behind, gesturing to ask him how he was doing.

When diving, the biggest obstacle is not the water pressure and cold water temperature, but the mental state. The underwater light is very weak, and the surrounding cold water can cause great psychological pressure to people, making people feel helpless, lonely and afraid, which is the most harmful to divers.

Qin Shiou is most accustomed to this, because he has the heart of the sea god, and he never feels lonely and afraid in the water, he is like the king of the water, this is his territory, in his own territory, why does he feel lonely and afraid? (To be continued......)
