This is a valley with an elevation of about 180 meters in the data: the northeast side is the main peak of the entire mountain range, and the highest point is more than 1,400 meters above sea level. The west side is only more than 20 meters above the bottom of the valley, and above it is the original radar station.

There are two points drawn by Zhang Nan on this map. They are about 500 meters away from each other. There are some protruding small hills in the middle, both on the northeast side.

The first point is 200 meters ahead, and the distance from the barracks area is at most 300 meters, and the second point is still further inside.

Xiang Weirong also looked at the map carefully and said, "How about the method used in West Germany?"

"Well, try."

Zhang Nan nodded.

Putting away the map, leaving a few people, Zhang Nan walked five or six to the west and climbed more than ten meters up the hillside.

Stop at a place where your line of sight is not blocked, and take a look.

After a while, Zhang Nan said, "It seems that the place should be right."

Xiang Weirong and Guan Xingquan also nodded.

The old way in West Germany is to look at the woods.

This is a tropical rain forest area. The soil is the soil changed by volcanic ash that erupted in ancient times. The soil layer is relatively thick, and the trees grow very fast.

Even if there was a base built by the Japanese army in the 1940s, as long as it wasn't a permanent reinforced concrete building, it would have been reconquered by nature over the past forty years.

It is important to know that although the general rainforest is densely covered with vegetation, its soil layer is actually very thin compared to other landforms. The soil conditions here are very good, and the plants will grow as long as they go crazy.

Although this area is not far from Subic Bay, it is about 40 kilometers along the road. Coupled with topographical and historical reasons, this area has not been traced by human activities. This is the same as the village on the foot of the mountain ten kilometers away. The densely populated cities and towns are completely different.

In front of everyone who is prepared, two "simple forest roads" from more than 40 years ago will be depicted, with the ends on the northeast side of the hillside.

At this time, Xiang Weirong said, "The road on the opening will be too close to the construction site. Why don't you go and look inside?"

Zhang Nan nodded, and a group of people walked down the hillside.

Leaving Linman and Zach fooling around on the construction site, the others walked in, looking like the boss inspecting.

Others will not care what Zhang Nan and the group are doing. This is the boss's site. Moreover, the military training base is built in the valley. There will be a lot of things that need to be kept secret. Those who come to work and contractors have long been told to work in accordance with the project contract. Don't be too curious.

They are all veterans who have done the work of the US military base: honestly make money and take care of their eyes, ears and mouth!

Just now everyone looked from the top to the front. Although the plants in this area are relatively sparse, they can still find the difference in vegetation with their intentions: the color and the height of the trees are different.

The difference in color is due to the deviation of plant height caused by the types of surface plants and soil fertility problems, and there will be a difference in the line of sight under the sun. This is the same as the construction of a football field lawn.

It takes about 20 minutes to walk here. It’s more troublesome to walk here than in the slopes of the Alps. It has a rain forest climate. Then, a group of people was blocked by a large rocky **** already occupied by tropical plants.

There is a high mountain **** in front. Because of the tropical rainforest climate, such volcanoes are easily eroded by rain. There are already many messy rocks in this area.

If it weren't for careful observation, walking on the ground would not find the difference here at all, although there are too many broken rocks among the vegetation!

Without the boss and monitor, Chen Hao had already stepped forward to check it carefully.

After climbing up and down for a few minutes, Chen Hao said: "It's blasting, using a lot of explosives, at least 20 times that of the Germans."

It is better to be sure that it is blasting, and it is better to use a lot of explosives, which shows that the original project here is huge.

It's not an old mine temporarily selected, but a specially built fortification.

Looking at the stones that are almost disappearing in the vegetation, Guan Xingquan said: "The US military at that time is also strange, so it's not a good idea to check these possible mines."

Zhang Nan said: "There is no way to check, and besides, the U.S. military will not be interested in the little devil's things, except for gold."

In fact, Guan Xingquan also knew that when enjoying the fruits of victory, who would spend great efforts to investigate these bombed tunnels.

No one wants to do thankless things.

Little devils like to dig tunnels everywhere in Southeast Asia. Saipan and Iwo Jima are dug like ant nests.

In the middle of the Pacific War, the U.S. military was so energetic that the little devil had to dig holes everywhere for defense. Especially in Iwo Jima, the volcano is said to be almost hollowed out.

The effect of deep digging is very good. Although the U.S. bombs and the super-heavy artillery shells fired by the battleship cannons are powerful, there are often no shells for these fortifications.

Luzon is mountainous, not far from Subic Bay, and there are many fortifications such as tunnels dug by the little devil.

While the US military returned to fight in the Philippines, the little devil estimated that it blew up countless tunnels, underground fortifications and tunnels.

Just like in Iwo Jima, for the bombed tunnels, the U.S. military has no interest in digging them up again to see what happens inside. UU reading www.uukanshu.com is still waiting for the little devil to suffocate and get out of it. Come.

Those that the devils took the initiative to blow up are even more ignored: if the ammunition that cannot be taken away, the Americans dig out the treasure?

Too lazy to dig.

The vegetation is messy and the landslide area is huge. Zhang Nan thinks that it is best to determine the location of the hole relatively accurately. This will save a lot of time when using a large excavator to excavate, otherwise the amount of work is not small.

I asked Chen Hao if he could do anything.

"Yes, I have discussed mine and tunnel construction with Xie Gong and others, and there are professional artificial seismic instruments that can be operated.

By receiving the seismic waves generated by artificial blasting with a very small equivalent, the instrument can reflect the general geological structure of the nearby underground.

If there is a hollow tunnel, the instrument can easily detect it. "

Zhang Nan asked immediately: "Can you do it?"

"Yes, Xie Gong and they will use it. I can learn it. It sounds very simple."

Hearing Chen Hao's answer, Zhang Nan nodded and said: "When I go back, I will buy one.

Change the people here next month and get started when the time comes. "

There is always a place to buy this instrument when there is money, and the same goes for excavators. Those American contractors can get it, and they can do it themselves.

As for the excavator who can't find a suitable one, it's okay, Zhang Nan can deal with it by himself.

It's not a difficult **** repair. Don't talk about the beauty and quality, just dig the stone: the **** is not too big, so you don't have to worry about it collapsing.

There are so many people now, and we will talk about it after the camp's infrastructure is completed.

"The yacht is also transferred, and it is estimated that it will not be less than Berchtesgaden."

Think about it in my heart, if this is the legendary "Fortification No. 8", then the "Sunshine Star" is too small and too small, and you have to get a transport ship.
