Xiao Gao searched around the sea and couldn't see any trace of Chen Xiu, the cooler his heart became, and he couldn't help but think: "He can't sink into the sea!"

At the moment, I dived directly without an oxygen cylinder, but when I dived to more than 20 meters, the bottom of the sea was already pitch black.

Even if the water is clear, the light is maintained at most about 20 meters, and the sunlight does not shine at the bottom. Usually, when they go down to salvage the things on the wreck, they will also bring light sticks and lighting tools.

"No way!"

After diving a few more meters, the greater the pressure of the surrounding seawater, Xiao Gao also felt the higher the pressure in his ears when he dived naked, and there was a unilateral ear ringing.

"Go up and put on an anti-stress suit and come down with an oxygen cylinder, no matter whether Expert Chen is dead or not, you must find him!"

Xiao Gao dived quickly, and before he leaked out of the water, he saw a young face looking at him from top to bottom, who was Chen Xiu.

I looked for him under the sea for a long time, he actually came up by himself, Xiao Gao was angry and didn't come to one place, if it wasn't for the fact that this time the dive was a little long, he couldn't breathe, and he was going to scold on the spot.

"Team Xiao, Expert Chen's lung capacity is really amazing. Do you know how long he went down to dive for you? a full five minutes and thirty-eight seconds!"

One of Xiao Gao's diving team members said excitedly while pulling Xiao Gao up from the seawater.

"What's the big deal, isn't it just fifty or thirty...... Wait, how long did you say he was holding his breath?"

"Five minutes and thirty-eight seconds. ”

The world record for the longest time to hold your breath in water is 22 minutes, a record set by a Dane.

Chen Xiu's 5 minutes and 38 seconds is not worth mentioning compared to this record, but this number is a good result among many diver team members.

You know, Chen Xiu doesn't know how to dive, he has no professional training, and he doesn't know how to ventilate underwater, this lung capacity is definitely amazing enough!

Xiao Gao looked at Chen Xiu with a surprised expression, and asked with some uncertainty: "Expert Chen, you really haven't learned to dive before?"

Chen Xiu shook his head seriously, seeing the surprised faces of Xiao Gao and his teammates, Chen Xiu was also secretly glad that he came up in advance, otherwise he would have behaved too demonicly, I don't know if they would have regarded themselves as monsters.

It turned out that when Chen Xiu surfaced, he could still continue to hold his breath, and according to his own conservative estimate, it would not be a problem to hold his breath for another five minutes. I just don't want to act too strongly, so as not to attract unnecessary attention and surface early.

Seeing Chen Xiu's serious face, and then thinking of Chen Xiu's ugly swimming style when he was swimming just now, it seemed that he had indeed never learned to dive, and couldn't help but sigh and said: "Expert Chen, you have such excellent physical fitness, if you start training since you were a child, you will definitely have a chance to win the world championship!"

However, as soon as he remembered Chen Xiu's identity as an expert in the archaeological team, Xiao Gao suddenly felt as if the so-called diving world champion was not attractive to Chen Xiu.

With such a young expert, it is obvious that Chen Xiu's status in the archaeological world is no worse than that of a world champion.

At the moment, he quickly changed the topic and said: "Your lung capacity is so large, it is much easier to learn to dive." Next, I'll tell you to wear a device and some special communication gestures under the sea!"

As Xiao Gao said, Chen Xiu's lung capacity is there, and learning to dive is twice the result with half the effort, as for the gestures of wearing equipment and underwater communication, Chen Xiu learned it in less than half an hour.

An hour later, Chen Xiu was already fully dressed, with a hemp rope hanging from his waist, an oxygen cylinder on his back, and a glow stick diving to a depth of forty meters.

Originally, Chen Xiu could continue to dive, but Xiao Gao was worried that he would have an accident on his first dive, and strongly asked him to float.

After this trip, Chen Xiu's diving training was officially over.

So much so that in the afternoon, Xiao Gao reported to Long Zhi that Chen Xiu had finished studying, and Long Zhi confirmed it several times before he dared to believe it.

"Captain Long, arrange for me to dive with the submersible. I've learned how to dive and I can't wait to see the shipwreck underneath!"

At this time, Long Zhi really couldn't find a reason to refuse Chen Xiu anymore, so he had to arrange for Chen Xiu to carry the submersible to dive on the same day.

......

The submersible, named "Dragon King", is a spherical machine, with a smaller space than a car, and can only carry two people at a time.

Chen Xiu was wearing a diving suit and sat in the machine with Shi Zhou, the operator of the submersible.

As the submersible descended, the light in the sea became dimmer and darker, and after crossing the 20-meter waterline, it was even darker.

When the submersible shook with a "bang", the submersible reached the bottom of the sea, turned on the lighting, Chen Xiu looked out through the transparent glass inside the submersible, and was stunned for a moment, his mouth couldn't close for a long time, and it took a long time to utter five words,

"It's such a big ship!"

When he first came to the maritime archaeology team, Professor Fang said that the length of the wreck was 151.18 meters and the width was 61.6 meters, but when you don't see the real thing, the number is always just a concept!

Chen Xiu saw the entity of the sunken ship with his own eyes at this time, and only then did he really know that one hundred and fifty-one meters away was such a long ship.

"What you see now is not one hundred and fifty-one meters, when it sank, twenty meters was trapped in the silt on the bottom of the sea, and when the ship sank, the entire hull was cocked at one end, and the keel could not withstand the fracture of the stern, and it was halved in half, and you can now see that the part exposed outside the silt is only more than thirty meters!" The voice of Professor Fang from the ship's headquarters came from the headset.

"This ...... And that's just part of the hull!"

Chen Xiu was even more shocked, and at the same time asked curiously: "What about the other half of the hull?"

"We searched within a hundred nautical miles and couldn't find the other half of the hull. This time it was Captain Long Zhi's voice coming from the headset, "The other half is probably not as lucky as this part, and the ship disintegrated after sinking, or was drifted farther away." ”

The submersible is installed with a small power unit, and under the power, the pilot Shizhou slowly drives the submersible to approach the wreck, so that Chen Xiu can also see the wreck more closely.

Although the surface of the wreck has grown a lot of seaweed and seaweed on the surface of the wreck after hundreds of years of immersion in seawater, he is even more surprised that the wood exposed to the seabed is still strong to the naked eye.

Chen Xiu couldn't help but ask: "What kind of wood is this ship made of, it can actually withstand the immersion of seawater for hundreds of years without rotting." ”
