During the important period when the reform plan was off to a perfect start, the research center was once again popular with the public. Mr. Yang Dezhu, our reform participant and the most important investor of the research center, took a few of his leisure women and started the voyage of the sea expedition again.

What is different from the past is that this time they have advanced nuclear submarines and other auxiliary tools, not only have a place to rest and take refuge in between, but also can bring more supplies. Of course, it is also possible to go further.

Seventy-one percent of the Earth's surface is covered by seawater. Therefore, human beings have never stopped exploring the vast ocean.

Ordinary people yearn for the ocean, and they can only watch documentaries to enjoy themselves. And Yang Dezhu now has this condition. Naturally, he didn't mind going on a realistic expedition.

The women who went to sea with him this time had Yan Rong, Qingtian Mei Gardenia, and Liu Qianqian.

They set off from Yangjia Wharf and started their way to the mysterious depths of the Pacific Ocean.

The mysterious underwater world is already very familiar to people like Yang Dezhu who have their own submarines. However, under the bright pinhole searchlights around the submarine, the ocean still looks far from colorful.

Beyond the colorful coral groves in the shallow sea, even the aquatic plants that can grow on the bottom of the deep sea have become scarce.

The submarine was equipped with all known channels, and Yang Dezhu chose one at random, activated the automatic navigation function, and then several people drank and chatted in the cockpit, sometimes discussing a certain species of underwater creature that they had never seen. Perhaps sometimes stop and take a closer look at a suspicious spot to see if it is a pirate shipwreck.

In fact, there are all kinds of terrain in the ocean. The trench is just a canyon on land. The bottom of the sea is as plain and hilly as it is.

The route chosen by Yang Dezhu passed through a plain, which is an endless submarine hills. Even if the submarine is advancing close to the bottom of the sea, the depth displayed is only more than 300 meters.

And Yang Dezhu wanted to try the feeling of going down to the deep sea of 500 meters to 1,000 meters. So at this time, there is still no desire to go into the water.

The submarine sailed for six or seven hours. Finally, a trench appeared. Although this trench is far less deep than the Mariana trench, it is seven or eight hundred meters. It just meets Yang Dezhu's requirements.

So Yang Dezhu quickly switched to manual driving, and then drove the submarine to explore the trench. Surprisingly, this place does not seem to be as inhospitable as it sees, at least as far as the submarine can see, there are still a lot of creatures moving.

However, the submarine is too large and there are some narrow places that cannot be detected, but it just meets Yang Dezhu's spirit of adventure.

Although Mitoriko Aota is the most powerful of the three women, it is only on land. When she got to the water, she was no match for Yanrong. Moreover, Yan Rong cultivates the same exercises as Yang Dezhu, and his physical fitness has been comprehensively improved, although he is not as perverted as Yang Dezhu, but he is indeed the best among all the women. Even if someone can catch up in the future, I'm afraid that only osmanthus with a special physique can have hope. So this time it was still Yan Rong who went into the water with Yang Dezhu.

Unlike the previous two impromptu surges, this expedition was much more prepared.

Yang Dezhu and Yan Rong are basically fully armed. A water-splitting steel fork in one hand and a deep-water hand crossbow in the other. The headlamps on their heads are all high-bright, which can illuminate everything in front of them clearly. in a row of buckles on the waist. Barrel of crossbow arrows. There is also a lot of underwater emergency equipment. Two high-pressure jet canisters are carried on the back, and the switches extend all the way to the wrist, allowing for flexible adjustment of the size of the switch. This gear allows them to start quickly, saving them the hassle of having fins. The fins were replaced with rather aggressive spurs. While allowing them to cling to the smooth stones of the seabed, they can also be used as offensive weapons.

Liu Qianqian activated a button, and the small water storage tank was immediately emptied by compressed air, and then closed from below. And the door above opened.

Waiting for Yang Dezhu and Yan Rong to go down to the small water storage tank. The upper door closed again, and the lower door opened. Then, as the compressed air is pumped back in by the pipes that recycle the compressed air, seawater fills the entire reservoir at the same time.

Wait until the indicator light is on, and the whole process is complete. Yang Dezhu and Yan Rong gestured to each other. After looking around the safety fence below for a while, and making sure that the surroundings were safe, he pressed the switch to open the fence and swam to the vast deep sea.

Hesitant has never descended to such a depth, and I don't know if their bodies can withstand it, so just now the submarine was parked at a depth of about 400 meters.

Yang Dezhu and Yan Rong adjusted to the sea water for a while, and felt that there was no problem, so they nodded to the submarine again and began to sink underwater.

Liu Qianqian and Qingtian Mei Gardenia in the submarine hurriedly controlled the submarine to adjust the water storage capacity of the four large water storage tanks, so that the submarine also followed Yang Dezhu and Yan Rong to slowly sink to the bottom of the sea.

With an increase in depth. The pressure under water is also increasing dramatically. is also thanks to Yang Dezhu and Yan Rong's bodies are perverted enough, if they are replaced by ordinary people. It has long been crushed by the sea. Because after more than five hundred meters. The pressure of the surrounding sea water will force the water into your skin. If you breathe. The pressure of the sea also puts carbon dioxide. Nitrogen. The ingredients in these ordinary oxygen are pressed into your blood, so ordinary people can't stand it. Only deep-water specialty oxygen can be used. Special oxygen: In addition to oxygen, other diluted ingredients are rare gases that are not absorbed by human blood cells. That's how you can stay safe.

And Yang Dezhu and Yan Rong have no worries about this. Because they have long since been transformed into a state of internal breathing. At this time, it is all the energy in their bodies that is consumed. So just deal with the pressure.

Descending above the trench, it is already 700 meters underwater. However, Yang Dezhu and Yan Rong's physical condition is still normal. It's just that further down, you'll find a criss-crossing narrow strip. The submarine had no way to follow them anymore, so Yang Dezhu and Yan Rong had to pay more attention to their safety.

Yang Dezhu gestured to the submarine to stop here, and then fixed the beacon light that emitted blue breathing light in all directions to the opening of the fence below the submarine. It's their last safe haven. It must be marked so that you don't get lost and can't find your way back.

After making these preparations, Yang Dezhu and Yan Rong began to explore these criss-crossing trenches.
