Along the way, the closer you get to your destination, the fewer villages and towns there will be. It is not surprising that all the people in the surrounding area of hundreds of miles were relocated for this project. After the completion of the project, it is unknown how many towns and historical sites were submerged.

"Brother-in-law, it's here!" In the early morning of the third day, Xiaolu sat in the co-pilot seat and pointed to the winding mountain road in the distance and said to Cheng Sen.

"That's so tall!" Cheng Senang sighed as he looked at the two peaks in front of him and the dam built between them. The dam is about a kilometer high, and people stand at its feet like ants. Perhaps, it is not even an ant, it can only be regarded as a speck of dust. Downstream of the dam is a large river with gentle water. The water of the river is crystal clear, and the banks are covered with lush forests. The dam is built on the basis of two peaks, and the peak just forms a big concave character. There are two peaks, one on the left and one on the right, each with a very smooth and wide winding road, which rises to the top of the mountain. These two roads are also the only entrances and exits to the upper and lower dams.

Between the peaks, ropeways are pulled for tourists to travel to and from. However, now because of electricity, it is obviously discarded. The top of the mountain was cut very flat by the machine. There are dozens of huge windmills on it, and Cheng Sen doesn't know that they are wind power generators. It's just that for some reason, the electricity from those windmills is not fed into the equipment inside the dam.

The east and west sides of the mountain have been built to be very smooth and level. From a distance, there seems to be some faint reflection on the cliff. Because the distance is too far, Cheng Sen doesn't know what those reflective things are. However, he knew that it was impossible to do useless work for such a large people's livelihood and national defense project. Since they exist, there must be a reason for their existence. He decided to wait until he was stationed at the dam to find out.

"Brother-in-law, look at this road, can you rely on it to build fortifications? It was laid up in circles along the mountain, and as long as we built a small cement fortress on it, it was very effective to stop the enemy below. Xiao Lu said to Cheng Sen with some excitement.

"You mean, on every ring of the road, a fortress has been built. As long as the enemy sets foot on this road, they will be blocked from above their heads, right? It's a good idea, but it's not realistic at the moment. How many people do we have, you think? I'm afraid that all of them will not be enough to hold a mountain. In the future, we will have more people in our hands, and you can consider this suggestion. After listening to Xiaolu's words, Cheng Sen smiled and rubbed his hair and said. Although Xiao Lu's suggestion was a bit unrealistic, Cheng Sen was still there to encourage him. Being able to take the initiative to contribute ideas to the team, no matter what the idea is, is always commendable.

"It's also Brother-in-law Ha, I forgot that there are only about 30 of us hehe!" Hearing Cheng Sen say this, Meng Lu scratched his head a little embarrassedly and sneered.

"We must occupy this place this time, and after a long time, the population will naturally increase. At that time, it is completely possible to build this place into an impregnable wall according to the advice of the path. But for now, let's hurry up. Seeing the destination, Cheng Sen's mood was also very good. Picked up the walkie-talkie at hand and half-joked there.

After driving along the winding road to the top of the mountain, Cheng Sen and his party finally arrived at the dam after two hours. Getting to the dam doesn't mean going to the top of the mountain, because these two mountains are just too high. Cheng Sen visually measured that if he walked, it would take at least more than 1 hour to go up to the top of the mountain!

The top of the dam is also very clean because of the long-term mountain wind. And the dam with a thickness of 12 lanes made Cheng Sen stunned and amazed. Not only that, but this world-famous dam is actually made up of two identical dams. The distance between the two dams is about two kilometers or so, and the distance between the dams is a buffer zone. During the rainy season, two dams close the floodgates to stop the torrent so that the towns downstream are not flooded. In the dry season, the floodgates will be opened a little to drain the accumulated water downstream, so that the towns along the water can be irrigated and drunk!

"There should be two power supply systems here, one that uses wind power at the top of the mountain, and the other that uses these rapids as hydropower. Don't be stunned, let's find out if there's a place to stay. You can't just stand here and look at the view, can you? Cheng Sen took out a cigarette, lit it a few times without lighting it, and said with some annoyance. Standing at the top of the dam, the wind was so strong that the lighter couldn't be turned on.

"Boss, come on!" Half an hour later, the voice of Fat Tiger came from the intercom. No way, it's just too big. So much so that after receiving Cheng Sen's order, after looking for half an hour, Fat Tiger found the place in front of him.

Cheng Sen and his entourage got into the car, and while asking about the specific route and situation of the fat tiger, they drove the car in the direction of the top of the mountain. After about 10 minutes, they reached the top of the mountain lined with windmills, and found the fat tiger next to a spiraling down staircase. The staircase is excavated down the mountain, and a semicircular doorway is made of reinforced concrete. On top of the doorway, a thick layer of soil was covered, and some weeds were planted on it. If it weren't for the fat tiger standing there, Cheng Sen and the others would really find this place.

"Damn, how did you find this place fat man?" Cheng Sen walked to the entrance of the cave, looked down at the retracted neck and asked the fat tiger. The bottom of the staircase was pitch black and bottomless, and if the entrance was not exposed, it was a good place for Tibetans.

"Well, I was in a hurry to urinate just now, so I was thinking about finding a big tree to cover it. When I finished urinating, I turned around and saw the hole behind me. It scared me at the time, I thought whose grave had been shoveled open! Fat Tiger blushed and explained to Cheng Sen there.

"Drive all the cars over and disguise yourself. Fat Tiger led a group to explore the road with me, and the others stayed on guard. If we don't come back after 1 hour, you will leave! Cheng Sen found a sheltered place, lit the previous cigarette, took two puffs and said to the people around him.

"That's not going to work, let's go down and go down together. We're all in this together, and we can't watch you go on an adventure! Meng Sui'er gritted her teeth and stood beside Cheng Sen and said.

"Don't make trouble, you and Su Linglong stay on top together. What's down there, no one knows. Fewer people go down, but it is better for us to act. If we really want to meet something, it will be convenient for us to retreat. 1 hour, obediently wait here for 1 hour. Cheng Sen knew that this stubborn girl was actually caring about herself, so he touched her cheek and said.

"Brother-in-law, take me with you. Maybe I can help you! Xiao Lu tightened the tactical vest on his body and walked out with a 95 semi-automatic on his back. What he meant Cheng Sen understood, once he said that there was a top secret place hidden here. And the code to enter and exit that place, now only he knows. And the path hasn't been broken yet, it's just that I don't want anyone in the team to have any different intentions. When everything settles, when Cheng Sen should let them know, he will naturally let them know!

"It's good! Follow me down the path, follow me after the afternoon, and don't move around. Cheng Sen pondered for a moment and agreed to Xiaolu's request. It's just that he really didn't know whether it was safe down there, and he opened his mouth and told the path a few words!

"Damn, I just found out today that Lao Tzu has a fear of heights!" By the light of the flashlight, the fat tiger moved down the stairs in front of him with some trepidation. People, for unknown places, always have a sense of awe. At this moment, the fat tiger held on to the railing on the outside of the stairs and said with a trembling mouth.

"Don't look down, the more you look, the more panicked you become, just concentrate on the road under your feet." Cheng Sen glanced at the bottomless abyss outside the railing and reminded the fat tiger.

I don't know how many steps I walked down, and when the fat tiger looked at the passage under his feet that had been excavated against the inner wall of the mountain and sealed with reinforced concrete. Then he let out a long breath, wiped the sweat from his forehead, leaned against the wall, and kneaded his somewhat stiff legs.

"This is the barracks~" Cheng Sen turned on the flashlight, walked along the passage under his feet for a while, and then retreated and said to the fat tiger who had already relieved himself.

"Boss, how do you know?" Fat Tiger wiped the sweat stains on his palms, looked up and asked Cheng Sendao.

"There are beds, simple furniture, and separate bathrooms." Cheng Sen pushed open a moving door and said with a flashlight. The steel-framed bed, the low bedside table, the walls plastered with cement, and the squatting toilet. One by one, the bright light of the flashlight appeared in front of everyone's eyes.

"The ventilation here is good, don't you feel that you have been down for so long, and you don't feel stuffy at all? It seems that this place was built with care. Cheng Sen shone a flashlight around and said to the soldiers.

"Poof~" Cheng Sen ripped off a signal stick and threw it down! The flashing red light of the signal rod spun and fell downward. Until the darkness annihilated the red light, Cheng Sen didn't hear the sound of the signal stick falling to the ground!

"It looks like the whole mountain has been hollowed out!" Cheng Sen retracted his head from the guardrail, slapped the dust on his hands twice, and said.

"Boss, can you let the people above come down?" The fat tiger really didn't dare to look down, and asked Cheng Sen with a sideways face.

"Don't be in a hurry, send a brother up to tell him that he is safe. Let's continue down the road, and if there had been a garrison here, I guess there must have been some monsters left here. Cheng Sen pulled the bolt, put the rifle flat on his chest, and said to Fat Tiger with a flashlight in one hand.

"It's okay, you go up and say to Squad Leader Jiang and them, and say that the boss is safe with us!" Fat Tiger reached out and patted the warrior next to him on the shoulder and said to him.

"This is the barracks, and it should be the place where the monsters are most concentrated. Everyone be careful and stick to the wall. Turn on the flashlights and shoot as soon as there is a situation! Cheng Sen hid the path behind him and ordered the soldiers.
