Happy Tycoon

To Yang Jing’s surprise, after opening this heavy watertight door, behind the door was a circular passage about two meters in diameter, and the passage was made of special steel, which was four to five meters long. On the opposite side of the passage, there is also a round watertight door.

Upon seeing this structure, Yang Jing immediately realized what the circular passage and the watertight doors at both ends of the passage were for.

Most of this base is located below sea level. Before the base was established, it was a natural cave formed during the eruption of a volcano.

Because the cave has no other place to communicate with the outside world, enough air pressure is formed in the upper half of the cave so that the sea does not flow up from below the cave.

It’s just that this cave was discovered accidentally by Onishi Takijiro's men. Because it was extremely hidden, Onishi Takijiro decided to transform this natural cave into a secret underwater base.

But you can't just walk underwater in and out of the base, right? After all, the steel gate is for submarines to enter and exit, and the water is too deep, and it is impossible for the soldiers on duty at the base to enter and exit through the underwater gate. Therefore, these soldiers on duty in the base must enter and leave the base from other places. And this import and export must be on the island, not in the water.

However, once an opening is made in this originally sealed cave, the air in the cave will inevitably be discharged by the sea, and then the sea in the cave will be at the same level as the outside sea level, and the base will be lost. effect.

Even if Onishi Takijiro does not understand this most basic physical principle, the engineer responsible for the construction of this base must understand. So in order to avoid this situation, those engineers set up such a passage similar to an airtight cabin here.

When someone enters or exits, first open a door, the personnel enter the passage, then close the first door, and then open the second door. In this way, the air in the hole will not leak out.

The two watertight doors and this circular passage play such a transitional role.

Moreover, although he did not inspect the interior of the base carefully and did not see the relevant oxygen generators, Yang Jing is sure that there are definitely oxygen generators in the base. After all, oxygen generators have been used in the early last century. The Germans researched it out. Although only Germans and French people in the world could make industrial-grade oxygen concentrators before the 1930s, with the outbreak of World War II, Japan had already learned the craftsmanship of oxygen concentrators from the Germans.

And this base was established in the 1940s, so it is absolutely impossible for the base to lack oxygen generators. Because the oxygen concentrator can not only generate a steady stream of oxygen for the base, but also continuously supplement the air pressure that the base consumes due to personnel entering and exiting.

After understanding the function of this passage and the two watertight doors, Yang Jing closed the first door, then walked to the other door and opened the second door.

Outside the door is still a natural cave, but there are several barracks, which should be the Japanese barracks guarding this base.

After walking along the road between the barracks for more than 40 meters, a diagonally upward ladder appeared in the line of sight. Looking up, the diagonal ladder stretched upwards for more than 30 meters, with a height of almost a little bit. About fifteen meters, at the top of the inclined ladder, there is still a round watertight door.

Obviously, this inclined ladder and the watertight door at the end of the inclined ladder are the entrance and exit to the outside world.

Yang Jing looked back at the base that came over, and roughly drew the structure of this base in his mind.

This base was built on the basis of a natural cave. The widest point is on the southernmost side of the cave, that is, on the side of the slipway. The east-west width is more than 100 meters, and the height of the cave is the largest, at least there. Forty to fifty meters high.

Then the base has been extended to the north, and the width becomes narrower as it goes north, and the height of the cave is constantly decreasing. Until more than 200 meters away, the base became more than 40 meters wide and 15 meters high. On the whole, this base is somewhat similar to a trapezoidal cube.

Yang Jing shook his arm, then grabbed the ladder and started climbing. After reaching the watertight door at the end of the ladder, Yang Jing tried to twist the **** on the watertight door. With a sour sound, the watertight door finally began to move.

When Yang Jing turned the **** to the end, the watertight door opened completely, but the watertight door was very heavy. Even with Yang Jing's strength, it took a lot of effort to finally open the watertight door.

The moment the door opened, the sun came in from the outside accompanied by a burst of warm air. Yang Jing climbed out and found out that he was on the gentle **** on the west side of Maugexi Island and was close to the foot of the mountain.

After drilling out, I discovered that there was mud and a few rocks scattered beside the door. No wonder this door is so heavy. It turned out that the top of this door was covered with mud at least half a meter thick, and a few rocks that had rolled down from the mountain were also pressed on it.

If you change someone, I'm afraid you won't be able to open the door underneath.

No wonder Chris and the others did not find the entrance to the base they had searched for on this island. This door is buried under the soil~www.readwn.com~ They don’t have special equipment for detecting metal, and the door is relatively small compared to the whole West Island and almost negligible. Chris again How is it possible to find this door?

Yang Jing stood beside this door, took off his mask and took a deep breath, before calling Chris and the others over the radio.

After a while, Chris and the others came out of the lagoon on a motorboat and saw Yang Jing standing at the foot of the mountain with strange faces.

After getting off the motorboat, a few bodyguards trot to Yang Jing's body. Chris asked strangely: "BOSS, we didn't see you coming out of the water, why are you standing here?"

Kevin Martin on the side said with a dazed look: "Boss, would you use the kind of transposition in "Harry Potter"?"

Yang Jing dumbly pointed at the big hole next to him, and only then did a few people see the open circular watertight door.

"Boss, is this the entrance to the base?" Thomas asked in disbelief, patting his forehead, "I went up the mountain from here yesterday. Why didn't I see this door?"

Yang Jing didn't bother to explain, but said, "This door leads to the base below. There are two entrances and exits in the base below, one in the water and one here. By the way, have George and Clark come up?"

"Not yet, but it's coming soon, Sean and Mark are staring over there."

Yang Jing nodded and said, "Let's take a break first. After George and the others come up, we will go down here again!"
