After Zhao Huang went to inquire about the boss, Wang Dong and the others immediately set off.

To the west of Mount Fuji, there is indeed a small lake, a reservoir to be exact.

The reservoir was originally built for agricultural irrigation, but in recent years, as arable land has decreased, the reservoir has stopped releasing water as often as it used to.

It's just that the environment is very good.

Because it is at the foot of the mountain, there are no hotels nearby.

When Wang Dong and the other four arrived, it was already midnight.

The water was clear and a bit cool.

Nothing wrong with that, though.

After putting on the scuba and putting on the oxygen cylinder on his back, Wang Dong entered the water first.

In fact, the water is not very deep, just over 10 meters.

The reservoir is also not very large.

It didn't take much effort for Wang Dong to find the problem.

What's the problem?

The water in the reservoir is flowing!

Although the flow was slow, Wang Dong could still feel that there seemed to be a hole at the bottom of the reservoir, a flood outlet to be precise.

Soon, Wang Dong found that location.

It's not a spillout, it's a pipe.

Fortunately, the pipeline is more than 2 meters old and looks decades old, for example, there are many underwater creatures on the iron fence from the pipe to the mouth.

When the others followed, Wang Dong demolished the iron fence.

The pipe goes all the way down, sloping down to be exact.

After swimming dozens of meters, Wang Dong stopped.

There was a bend in front of it, but at the top of the bend there was a gate that looked like a watertight gate, and it was certainly not very old.

Obviously, this is the place to be.

Get in?

If you don't go in, what are you doing here?

After reminding the others and telling them to be ready, Wang Dong opened the watertight door.

That's right, this is it!

Inside is a wet and dry isolation chamber, and it is fully automated, and after the watertight door is closed again, the water inside is automatically discharged.

"This is it!" After taking off the breathing surface, Zhang Zilan said that he was carrying a nuclear radiation detector.

Before entering the compartment, the radiation detector detected trace amounts of nuclear radiation.

"Get ready. If you encounter an enemy, fight quickly. ”

Wang Dong took off his wetsuit and took out the DF8SMG in the waterproof backpack.

Soon, the four were ready for battle.

Arguably, this is the strongest combat combination.

It's just that Wang Dong did not partner with Luo Qing, but with Lei Dong, and Zhang Zilan partnered with Luo Qing, mainly because Zhang Zilan and Lei Dong had no vicebrains.

If they meet Emily, the two of them basically have no ability to fight back.

Opening the inner door, Wang Dong paused slightly.

After confirming that there was no danger, he passed through the inner door.

When he went in, Wang Dong was immediately stunned.

It is indeed an underground base, and it is an astonishingly large underground base!

It's a huge underground cavern!

It looks as if the bottom of the reservoir has been almost hollowed out.

In fact, the bottom of the cave is at least a few tens of meters from the bottom of the reservoir.

Also, it is a man-made cave.

Of course, it must have existed for decades.

Apparently, this is a secret underground base built during World War II, and the amount of work is so large that it seems to be the central base of the area.

What was Japan doing here back then?

However, this is not an issue that needs to be clarified immediately.

Wang Dong didn't delay much and immediately started searching.

With radiation detectors, it should not be difficult to find a nuclear warhead.

It's just that it didn't take long for Wang Dong to find out that this was a big difficulty.

Why?

There is nuclear radiation everywhere in this place!

The dose is too small to pose a threat to the human body, but it is enough to interfere with the detector and prevent it from accurately identifying the source of the radiation.

What's going on!?

There is only one possibility, this place was originally a nuclear base.

A nuclear base built by Japan during World War II!

During World War II, Japan did have its own nuclear program and tried to build an atomic bomb, but before it could be built, it was attacked by a nuclear attack by the U.S. military, and then announced its surrender.

In addition, almost all of the information related to the nuclear weapons program was destroyed when Japan surrendered.

As a result, little is known about Japan's nuclear program during World War II, except for a rough inference that Japan's progress in developing nuclear weapons was very slow, far behind the United States, and even comparable to Germany's at the time, after all, Japan's industrial strength was not enough to support its huge nuclear program.

According to outside speculation, Japan's nuclear program during World War II remained at the stage of theoretical design.

Of course, no one knows how.

It didn't take much time for Wang Dong and the others to figure out the situation.

In one corner of the cave, there is a lot of slag, which at least looks like slag, but from the readings provided by the nuclear radiation detector, it should be high-quality uranium.

Apparently, Japan has been refining uranium in the past, but it has been progressing slowly.

Subsequently, Wang Dong and the others found dozens of skeletons in a separate room, and some of the skeletons were obviously different from their heads.

Japan's nuclear weapons scientists during World War II?

Whether they are dead or not, they are dead, and they are dying very tragically.

In another room, Wang Dong and the others also found some skeletons, and it was a prison cell, and those bones also had nuclear radiation.

What's going on?

Could it be that after the atomic bombings of Hiroshima and Nagasaki, the Japanese military captured some of the victims and locked them up for research?

As the search continued, so did the discoveries.

In one room, there are discarded, or rather completely obsolete devices, that look like tools used for research.

In addition, there is a room with strong nuclear radiation, more intense than other places, to be presumed, which was previously used to store nuclear materials.

Some explosives were also recovered, yellow explosives that had deteriorated to be exact.

After some investigation, it has been confirmed that this is a secret base built by Japan during World War II to develop nuclear weapons.

However, after the end of World War II, the base was abandoned.

It is clear that those Japanese who used to do research here, when Japan surrendered, did not admit defeat and then committed suicide en masse.

However, some of them were clearly executed, perhaps without the courage to commit suicide.

With these people, the secret of Japan's development of nuclear weapons was buried here.

Perhaps, after the war, the Japanese authorities did not know that there was such a secret base, and even if they did, they might not have made it public.

It's just that after looking around, Wang Dong and the others did not find any trace of the nuclear warhead.

Even if there is reason to believe that Emily has been here and hid the nuclear warhead here, Wang Dong and the others have not found any traces.

Obviously, the handling is very clever.

It's just that the nuclear warhead must be here, just hidden somewhere where Wang Dong and they haven't found yet!
