Chen Fei raised his voice and said, "Can you finish the words in one go?" What are you asking me to see? What is the top secret place for? ”

Lin Yuan said: "Since you can enter the underground command post, it means that the ventilation system of the underground command post is intact, you immediately ask people to check the pipelines of the ventilation system to see if there is a temperature regulation system in the command post, and if so, see if the pipelines go to that top-secret place." ”

Chen Fei said: "Okay, I'll investigate, but can you sue me first, what do you guess?" ”

Lin Yuan said: "In our time, what is particularly important to put in a cave? ”

Chen Fei said: "What is particularly important to put in the cave? Is it a ballistic missile? In our time, the strategic ballistic missiles of the Second Artillery Corps equipped with nuclear warheads are hidden in caves. ”

Lin Yuan said: "That's right, it's a ballistic missile!" I'm worried that the top-secret location is a ballistic missile silo, but I'm sure the Japanese will never be able to make a nuclear warhead. ”

Chen Fei said with a smile: "Although I don't know much about missiles, I also know that if ballistic missiles are not equipped with nuclear warheads, they basically have no combat value." ”

Lin Yuan said: "Then I can't watch the Japanese conventional missiles fall on our land!" ”

Chen Fei smiled: "Don't we have anything to defend against ballistic missiles?" ”

Lin Yuan smiled helplessly: "Do you think ballistic missiles are so easy to defend against?" The flight speed of ballistic missiles is extremely fast, and it is more than 7,000 meters per second outside the atmosphere alone, and when it falls to the ground, the potential energy will be converted into kinetic energy, and the speed will be even faster, and the radar will not be able to react at all. ”

Chen Fei listened while looking for the head of the engineering group, asked Lin Yuan what he said, and after receiving the reply from the head of the engineering group, he told Lin Yuan: "The pipeline of the air conditioning system did not go to that top-secret location at all. ”

Lin Yuan said: "The thing in there is definitely not a ballistic missile, and the ballistic missile needs to be in a constant temperature environment." ”

Chen Fei then asked, "If it's not a ballistic missile, what would it be inside?" ”

Lin Yuan shook his head and said, "I can't figure it out either, so let's send an expert to the Emperor's command post in Hiroshima to see if there is a way to open the collapsed mountain." ”

During this time, Lin Yuan's troops, as usual, confiscated the assets of the chaebol in Japan, stabilized the market, and carried out land reform in the countryside.

After carefully inspecting the mountain, the experts found that the rocks of the mountain were very solid, although the top of the top-secret site collapsed, but if the rocks were dug out, the mountains would not collapse completely, that is to say, if the rocks were dug out, the original face of the top-secret site would be revealed, so the experts decided: send troops to dig out the rocks that collapsed, because the top-secret site is located inside the command post, so large construction machinery cannot enter, and can only be excavated manually.

However, some rocks are relatively large, manpower can not be transported out, experts have thought of the method of directional blasting, first use a drilling machine to punch holes in the rocks, and then put the explosives in to detonate, the explosion can blow the rocks into small pieces, and then people dig out the small pieces of rocks.

As soon as this plan was decided, it began to be implemented, and the engineering regiment of the second division put down all other tasks and dedicated it to this matter, Chen Fei also stayed in the command post, and the excavation was carried out for six hours, and the commander of the engineering regiment came to report to Chen Fei: "Division Commander Chen, we have cleared part of the mountain rocks, and some top-secret locations will soon be exposed." ”

Chen Fei stood up excitedly and followed the head of the engineering regiment to the construction site, only to see a group of soldiers busy in front of the mountain wall, they were sweating profusely, shoveling up the rocks with shovels and putting them into the trolley, and some soldiers pushed the trolley to transport the rocks outside.

The head of the engineering regiment said: "Senior Commander Chen, please wait a while, we will soon clear this section of the rocks." ”

Chen Fei sat next to him while agreeing, he took out the communicator to contact Lin Yuan, and said, "We are cleaning up the rocks now, and it is estimated that we will soon be able to see the true face of the top-secret place, by the way, what are you doing now?" ”

Lin Yuan smiled helplessly: "Are you here to chat with me?" ”

Chen Fei smiled: "Aren't I idle and bored!" I can't move stones with the soldiers, by the way, I found that the Japanese emperor is very simple, he doesn't even have a bed, only a shelf made of wood as a bed, you look at you again, there is a bed to sleep on! Compared to him, you are simply the first faint king of the ages......"

Chen Fei and Lin Yuan chatted casually, Lin Yuan ignored him, put the communicator aside, and then went about his own business, from time to time "um, ah", Chen Fei thought that Lin Yuan was listening carefully, more than ten minutes passed, the head of the engineering regiment came over and said to Chen Fei: "Master Chen, a part has been dug out, please go over and take a look." ”

Chen Fei turned off the communicator and followed the head of the engineering regiment to the excavation place, and the head of the engineering regiment pointed to the ground and said: "Commander Chen, you see, the ground is paved with cement, which is very different from the ground in other places, and it is obvious that this is the top secret location that the Japanese have painstakingly covered up. ”

Chen Fei squatted down, gently stroked the cement floor with his hand, and said, "This cement floor is very ordinary, right?" ”

The head of the engineering group said: "That's right, it's very ordinary, this kind of cement in our China brand is 'GSY-1-600', 'GSY' stands for 'silicate', indicating that the main component of this cement is 'silicate', the back '1' stands for 'applicable to various industries', '600' represents the compressive strength is 600 megapascals, this is ordinary cement that can no longer be ordinary, I see that the top secret site is still inside, we need to dig deeper." ”

Chen Fei thought for a while and said, "Okay, you guys just keep digging." After Chen Fei finished speaking, he sat back in his chair, took out the communicator and continued to chat with Lin Yuan, and after about half an hour, he heard a soldier shouting: "It's over!" It's over! ”

Chen Fei hurriedly stood up, came to the head of the engineering regiment, and asked, "What's the end?" ”

The head of the engineering regiment pointed to the front with his hand and said: "The cement floor is over, and if you dig in front, it will be a mountain." At this time, the tunnel expert came over with a tape measure, beckoned someone to measure the distance, and said to Chen Fei after a short time: "Master Chen, the north-south direction of this cement floor is seventy meters, and it has come to an end, if you want to understand the situation of the top-secret site, you must continue to dig to the east and west." ”
