When Gu Changhui, Xue Ming, Zhang Yi and other personnel rushed to the military district guest house of the local garrison in City C to join up with a group of professionals who had arrived in advance, Gu Changhui felt that he had a heavy responsibility, and in the face of the trust of the organization and the experts and heroes gathered in front of him, if he did not bring out an invincible elite army, he would not only fail the hope of the organization, but also be ashamed of these experts, teachers and soldiers from all over the world who were destined to work in this barren primitive mountain for several years.

Almost all of these people are leading figures and professionals in various fields of the armed forces, many of them are in the prime of life, and many of them are heroes, pacesetters, and training experts who have served in the army for many years; although they come from different specialties and different organs and departments, a common characteristic of these people is their absolute loyalty and love for the party and the army.

At that time, the people were simple-minded, carried out the orders to the letter, without complaint or regret, and none of them stretched out their hands to ask for conditions, because they regarded the trust of the organization as a kind of honor, regarded the army as warmer than home, and regarded the honor of soldiers as more important than their own lives.

Xue Ming was more concerned about whether the human air defense fortifications, which were the future training base, could meet the needs, so as soon as he arrived at the guest house, he drove himself and a guide directly to this secret world deep in the mountains.

After passing through the camp area, passing through several checkpoints, and driving for more than an hour on a gravel road in the dense primeval forest, the car came to a large naturally formed cave halfway up the mountain, which was difficult to find if you did not come to the front because of the dense forest cover. It was noon, but the cave was pitch black, and from a distance you could see that there was a faint light on the top of the deep cave, but it did not work at all in the huge space, at best it was only a guide.

Just as Xue Ming was wandering and observing outside the cave, the instinct of the scout made him realize that someone was moving towards him nearby, Xue Ming did not move, and slowly took out his ID from his jacket pocket, and in an instant, several guns forced him, and the leader took his ID. The guide, who was briefing Xue Ming on the side, hurriedly walked over and said, "Squad Leader Chen, this is Comrade Xue sent by the superiors, and I have greeted you. ”

Squad Leader Chen was unmoved, took Xue Ming's certificate and checked it carefully, and then handed it to Xue Ming, and said in a straight voice: "Report to the chief, the resident guard squad is here to guard, please instruct." ”

Xue Ming smiled: "Thank you, hard work, I just came to see it today, there is no arrangement, you continue to be vigilant." After speaking, Xue Ming returned a military salute very standardly.

Squad Leader Chen took a military walkie-talkie from a bush next to him and informed him that the door was ready to open.

Xue Ming got into the car and drove towards the depths of the cave, zigzag and turned for about a few hundred meters, and a huge cave door appeared in the field of vision, and this place was obviously much brighter than near the cave entrance. The door of the cave only opened a crack, but it was enough for Xue Ming's jeep to drive in unimpeded, when passing through the gate, Xue Ming was stunned by the thickness of the gate, at least nearly one meter thick by his eyes, it was completely made of steel plates and concrete, and the guide next to him saw Xue Ming's surprised expression, and said with a smile: "It's very thick, this is designed according to the standard of anti-nuclear weapon attack, and this is only the first door, there are two doors like this, each door is so thick, but the material is slightly different." Sure enough, after passing through two more of the same gates, Xue Ming and the others were stopped again.

At this time, the guide got out of the car, said a few words to a person from the opposite side, turned to Xue Ming and said: "Chief, I can only send you here, according to the regulations, I can't enter inside, he will take you inside, I will wait for you here." After saying that, he saluted and walked to a very secret hut next to him.

Xue Ming thanked him, turned around and drove towards the depths of the cave with the comer. At this time, Xue Ming's mood could no longer be described as surprised, but could only be said to be very shocked. The comrade next to him gave a general overview of this air defense project.

Xue Ming they were lucky, because this air defense project was basically not put into use after it was completed, and the era when it first began to be built should be traced back to the War of Resistance Against Japanese Aggression after the Kuomintang moved to the rear, at that time, in order to avoid the day and night bombardment, many important facilities and personnel were evacuated to the mountains, this cave was rebuilt by using a bottomless and natural cave at that time, and it has been expanding after liberation, especially in the years of preparing for war and preparing for famine. The construction of the small third line was intensified, and the cave was expanded and rebuilt several times, and it was only completed in recent years, when the ten-year catastrophe had just ended.

Xue Ming finally parked the car in a large open field in the cave, surrounded by countless lanes, and some places were sealed. At this time, Xue Ming didn't know how far he had come in, he thought it was over, but he didn't expect that the staff member took Xue Ming to a few turns and came to a near an iron gate, pressed the switch, the door opened, it was an elevator, and the staff motioned for Xue Ming to go in. Along the way, the staff had already roughly introduced the scale of this air defense project, but Xue Ming still couldn't hide his surprise, the area they passed by just now was only the place where the guards on the periphery of this air defense project lived and worked, but now it was empty.

When Xue Ming stepped out of the elevator and the staff turned on all the lights, he felt the meaning of "small" and sincerely admired our engineering soldiers.

He was ...... blown away by the grandeur of the place.
