The name Cangsanku is not a secret in the Korean People's Army, but no one knows where it is. Most people know that it's in Goryeo, it's in Pyongyang, but no one knows where it is. Even the world's top agents have not been able to find out the exact location.

They are very confused, according to intelligence, in that longitude, in that dimension. However, the building where Jingwei is locked cannot find the so-called Cangshan Library at all. As a result, they are skeptical of the accuracy of the source of the information.

In fact, the information is accurate, but the reason why it cannot be found is because the Cangshan Reservoir is not on the ground, but underground. And on which basement floor, it is even more unknown.

In order to prepare for the war, the major cities of Goryeo spent a lot of manpower and material resources to dig tunnels and make bunkers. Its degree of protection even exceeded that of Germany during World War II. This is also one of the reasons why Meiguo does not dare to act rashly.

Just imagine, what can a country where all the people are soldiers, even if it is invaded and occupied? Iraq is a good example of this, where the loss of soldiers and the weapons consumed simply outweigh the losses.

In the attack on Goryeo, it is expected that the loss of troops and weapons will be several times or even ten times that of the Iraq war. This is not counting the support of the Celestial Empire and Russia, and if the two countries do support, it will be even more immeasurable.

Meiguo would not do such a stupid thing, and would never let history repeat itself. Therefore, Meiguo has adopted an economic blockade strategy. In today's society, economic blockades are often fatal.

For example, a certain country has been under economic blockade for a long time, and although its people are still living well, they are very backward in weapons and everything. As a result, as soon as the rebels were dispatched, they were defeated and retreated, and finally died and were destroyed.

Gao Li also had such a problem at this time, but Jin Sanpang was not stupid. We are actively pursuing an open-door policy and are working hard to build our own economy. In the research and development of weapons, we have also vigorously invested resources and strength, in order to avoid the end of those tragic countries.

For the reserve of resources, Goryeo is actually not a lot at all, and it can even be said that it is very thick. It's just that foreigners don't know, and they speculate wildly based on some appearances.

Zheng Feilong walked along the underground road, went around for almost ten kilometers, and after almost twenty hurdles, he finally came to the legendary Cangshan Reservoir.

Don't look at it very easily, it's far more complicated than you can imagine. However, for Zheng Feilong, it is not so difficult to solve, but it will take a long time. Fortunately, everything went relatively smoothly.

I thought that in Cangshan Library, there would be many people guarding it. After all, this is an important place to concentrate supplies, but there are none. The reason is simple, that door ...... Can't open.

It's not that the door is very high-tech, in fact, there is no technology content at all. If I had to say anything, it would be heavy. It's as simple as that, it's heavy.

Goryeo is rich in copper, and the hotel's water supply pipes are all copper pipes. Naturally, this door is also made of brass, which is very thick. If you are too plain, it will look unartistic. However, he didn't carve the portrait of the second fat, probably because the second fat was built. At that time, it was not popular to commemorate Yipang activities, so there were no art photos of Yifat.

The portraits carved on it are actually some classic movie posters in the West, and even the movie titles are also carved on them.

But it's understandable when you think about it. Erfat loves movies very much, and has personally instructed actors to act many times. According to the narration of the husband and wife director in the Han Kingdom, who made a movie for Er Fat, in Meiguo, Er Fat has a very deep understanding of movies. The artistic attainments of photography are also very deep.

Zheng Feilong knocked on the door, there was no sound at all, and the thickness can be imagined. Even if it's unlocked, if you want to push the door open, you'll have to use a giant car. No matter how developed Zheng Feilong's muscles are and how good his internal strength is, he is just an ordinary person after all. If you want to open it, it's a fool's dream.

Zheng Feilong had no choice but to give up and prepare to return the same way.

However, there is a way that is "the way of heaven and no man".

Just when Zheng Feilong was about to give up, there was a sound of a locomotive starting in the distance. In this underground tunnel, it is especially clear and harsh.

Zheng Feilong wondered in his heart, could it be that someone found out?

When you think about it, it doesn't feel like it. So I hid in a tributary channel of a sewer to see what was going on. Even if it is discovered, it is very easy to break through with your own skills.

It didn't take long for the locomotive to get closer. It was an awl-shaped locomotive that looked like a submarine, about five meters long, which was not that huge.

The car stopped in front of the big bronze gate, and a few soldiers came out of it, and stood in front of the locomotive first, fiddling with it for a while. It didn't take long for the shape of the front of the car to change. Originally, it was an awl-shaped, but when you played it, it turned into a discus throw. Apparently this thing is meant to be used to hit things.

Zheng Feilong watched from the sidelines, wondering in his heart, are they going to open the door?

After that, the locomotive was really hitting the door, and a screeching sound came, and the bronze door was slowly recommended for half a meter. Then there were two loud "clicks", and the bronze door slowly opened to both sides, slowly showing the interior of the Cangshan Library.

Zheng Feilong has seen so many mechanisms, what thermal detectors, infrared scanning, voice-activated alarms, all kinds of intelligent induction. But compared to Gao Li, it's just too far behind.

If it is clumsy, it is not a coincidence! It's simply the best interpretation of this door.

Not only do you push the huge bronze door from the outside, but you also have to hook the handles on both sides of the copper door from the inside, and then pull it open to both sides. Based on the surveillance seen along the way, it is impossible to do so without being detected.

After the bronze gate opened, the locomotive drove in.

From the tributary pipe where Zheng Feilong was, he couldn't see the situation inside the warehouse, and he had to get close to it if he wanted to listen.

He listened with his downwind ear, which was much more sensitive than normal ears, and there was no one nearby. So he tiptoed a little and rushed over at a rapid speed. Before the locomotive could enter, he ran to the back of the locomotive, grabbed the bolt with the protruding suffix, and stood up.

The warehouse was full of shelves, and the first few rows of shelves were all rifles uniformly equipped with the People's Army. Backwards are magazines, and then grenades and the like.

One shelf has three tiers, and one floor has thirty guns. Three rows on one side, each with twenty shelves. Here is stored the equipment of a battalion.

Goryeo lacked supplies, and although weapons were produced, they were not well equipped. The equipment here is very adequate, even on par with the elite troops of many countries. It seems that this is intended for special forces, presumably some of the special forces' equipment depots.

Thinking about it, it is understandable that there is a shortage of medicine in Goryeo, and it is impossible for ordinary troops to dispense much. Those who can be equipped with a lot of high-grade medicines, of course, are special forces.

The locomotive drove further back, and after a short time, it stopped.

Zheng Feilong didn't know if they had found him, but he still jumped down cautiously. Lying on the ground, he pushed his hand to the ground and ran into the bottom of the car.

Just after Zheng Feilong scurried to the bottom of the car, two soldiers stepped out of the car. Ran to the shelves on both sides, took out military boxes, and put grenades or something in them.

Originally, this was nothing, and it was probably some kind of troop supply item. But later, when the two soldiers picked up something like a disc, Zheng Feilong immediately became uneasy. How could Goryeo have such a thing?
