It took a few days for the satellite phone and satellite navigator to be delivered, and Su Ji took advantage of these days to learn all kinds of geographical knowledge from Shang Xialiu. From the stars, climate, ocean currents to various marine disasters and more.

Su Ji wants to go to the ocean, it is impossible to float on the ocean every day, he must dive to the bottom of the sea to see. Shang Xialiu was not too worried about the ocean that Su Ji was going to do, he was particularly worried about his deep dive, and when he heard that he was going to dive deep, he asked with concern: "How many meters do you usually swim and dive?" ”

"I don't know how deep it is, I didn't pay attention to this problem, there must be tens of hundred meters." Su Ji asked, "What are you asking for?" ”

"The deep sea is very stressful, and diving is a very dangerous behavior." Shang Xialiu said seriously.

"I know that the deep sea is stressful...... Su Ji has seen a certain funny cartoon that talks about diving on the surface, but in fact it is about drinking, talking about the water of life, and has a lot of diving knowledge.

"You may know that diving is dangerous, but you may not know how dangerous diving is." Shang Xialiu pondered for a moment and said, "Diving more than ten meters belongs to the range of activities of professional divers. At this level, the pressure in the water increases significantly, which will lead to an increase in the pressure of the gas inside the human body, and if you do not go through professional decompression steps when returning to the water, it is very easy to cause decompression sickness, which is fatal enough. ”

"I'm no ordinary person." Su Ji puffed up his chest and said confidently.

"I know you're not an ordinary person. But you have to know that the ultimate depth of the general submarine is a few hundred meters, that is, the deepest submarine is about a thousand meters...... It is said that in one or two years, Hollywood director Cameron took the Deep Sea Challenge and dived to a depth of 11,000 meters, setting a human record for deep diving, and after the submersible returned to the surface, the length was directly compressed by 7 centimeters. ”

"I know there's a lot of pressure in the sea, but since there are deep-sea fish in the deep sea, they won't be flattened by the huge pressure, so I'm sure there's no problem." Suji said, "I'm Long Ye. A dragon that ascends to the sky at the spring equinox and dives into the abyss at the autumn equinox. There's no reason you can't dive deeper. ”

"You're thinking about those things too simply." Shang Xialiu looked at the confident Su Ji, "You shouldn't be better with deep-sea fish, people have been living in the deep-sea and have already adapted to that pressure." ”

"You usually live on the shore, but now you are a deep dive, and you should compare it to those animals that are also diving deeply. Sperm whale dives reduce the size of their lungs to increase the pressure in their bodies, and they protect their internal organs from the huge water pressure by wrapping them in a flowing blubber-like substance, even if they can dive up to 3,000 meters. ”

"My physical fitness is definitely better than ......that of sperm whales," Su Ji bit his lip and said, "I know that diving is definitely dangerous, but I still want to dive." One of the reasons I wanted to go ocean was because I wanted to go deeper than the continental shelf. ”

"I'm not telling you not to dive." Shang Xialiu shook his head and said, "I know I can't stop you, and I don't want to stop you, I still want to hear you say what the deep sea is, I just hope you can pay attention to it." ”

"Notice what?"

"Whether it's diving or floating, don't go straight up and down, try to dive up and down diagonally, take the stairs into the bottom of the sea instead of falling into the bottom of the sea, so that the body can slowly adjust to the water pressure." Shang Xialiu raised his hand to draw a slash.

"I will." Su Ji nodded.

He didn't mean to perfunctory Shang Xia Liu, he has always listened to people's advice.

"If you're stressed, don't dive anymore."

"Of course." Su Ji said affirmatively, suddenly remembering something, "It is said that the deepest place in the sea, the deepest trench is called Ma He Trench." ”

"The Mariana Trench, with a total length of 2,550 kilometers, an average width of 70 kilometers and a maximum depth of 11,000 kilometers, is the deepest known ocean. High water pressure, complete darkness, low temperatures, low oxygen levels, and a lack of food resources make it arguably one of the harshest environmental regions on Earth. ”

"The average width is 70 kilometers, and there is a trench."

"It's a trench for the whole sea."

"I wonder what's there?"

"Just check it out."

"I don't know if there's a SpongeBob SquarePants."

"There shouldn't be any animals in the deepest part of the Mariana Trench."

"I just knew that the trench was so wide, I always thought it was a dark rift tens of hundreds of meters long...... If you just swim in, I don't know if you dare. "I don't have a phobia of the deep sea, but I'm not really afraid of anything. ”

He thought to himself that he used to play World of Warcraft, and Xia Hou Yue was afraid of the underwater map Vaskir, but he had a lot of fun, Xia Hou Yue would jump up in fright when he was doing a task on that map because of the whale shark that suddenly appeared behind him, and he almost didn't feel anything.

"Do you want to go to the Mariana Trench?" Shang Xialiu asked.

"I'm going to check it out." Suj said, "Where is that Mariana Trench, is it far?" ”

"It's really not far from our current city...... Strictly speaking, it is far away, but compared to so many countries in the whole world, my country is not too far from there. ”

"How long does it take to swim through?"

"If it were you, even if you could swim 100 kilometers an hour, it would take a few days."

"So far away......."

"We can fly to the Philippines and then swim to the Mariana Trench."

"Is it easy to get a visa for the Philippines?"

"It's not difficult, if it's urgent, it's almost two days."

"Can I leave it to you?"

"No problem."

"That's it." Su Ji, who had made a decision, felt that he needed to relax, so he stood up and stretched his arms to stretch his waist.

The two of them basically stay in the hotel these days, and they dress quite casually without going out.

Anyway, Shang Xialiu was wearing a loose T-shirt at this time, sitting on a chair next to the TV cabinet and operating the tablet with her head down, and Su Ji wanted to see what she was doing with the tablet, and at a glance she saw the white and tender skin in her collar. There is no obstruction, all the light is gone, and to be honest, there is nothing to see.

Su Ji had the heart to remind her, but was worried that reminding her would cause embarrassment, so she quickly moved her gaze to the tablet, couldn't help but take another look, and then saw Shang Xialiu reaching out and pressing the collar.

"See?" Shang Xia Liu didn't raise his head.

"Huh...... What do you see, what do you say? ”

"Chest, my chest." Shang Xialiu asked bluntly, instead of encountering embarrassing things like other girls and treating them as if nothing had happened.

Su Ji was able to change the topic at most, and he was embarrassed to admit it, so he could only support it.

"Is my breasts better than the cricket's breasts?"

"I haven't seen her."

"You really don't have anything to do with her."

Shang Xialiu didn't pursue it, and didn't seem to care too much, Su Ji was relieved, and inexplicably felt that the atmosphere in the room was a little ambiguous.

It couldn't be so quiet anymore, but to say something, Su Ji spoke: "I heard that there is an aquarium nearby, have you been to see it?" ”

"Nope."

"Study for a few days, take a break once in a while, and go see it in the afternoon."
