While He Tao and his son were arguing over whether to attend the court hearing on site or watch the live TV broadcast, at the newly built Tamengye Military Research Institute, strict inspections of improved and replacement parts, armor, and electronic equipment delivered by various units were being carried out. testing. The Military Research Institute is deeper than the Tamengye Training Base into a mountainous area full of primeval forests. It crosses a saddle-shaped low mountain range to the northeast and is located in a five-kilometer-long valley. On both sides of it, there is a big mountain. The absolute height of the mountains on both sides is not particularly high. The peaks are only four or five hundred meters high, but they are very steep and the mountains are very wide. The mountains on the west side run northeast-southwest, and there are continuous mountains for more than ten kilometers to the west, all the way to the plains between Guigai Muse. The mountains on the east side are in the shape of a trapezoid. The northern section at the end of the valley is narrow, about seven or eight kilometers. The mountain at the mouth of the valley is relatively thick, about ten kilometers long. Over this mountain, there was the original confrontation between the Su Ding army and the base area. The frontier town of Micah. The Military Research Institute is surrounded by mountains and primeval forests, with only one passage leading to Tamengye in the southwest. Putting it here, the confidentiality and anti-espionage effect is excellent, and with the valley as the center and the surrounding mountains, it is just right to dig holes in the mountains and hide a large number of important military industrial enterprises and research institutions in the mountains. With the protection of the mountain above and the virgin forest blocking the detection and observation from above, even if an enemy plane comes to bomb, it will be difficult to cause a serious blow, further strengthening the security of this military research and manufacturing base. On the way Guan Fei came by car with the base area and the domestic expert team, not a single person appeared. There are long mountains and high and low hills on both sides of the road. Looking from the car, there are tall and straight primeval forests everywhere. Large tracts of broad-leaved trees cover everything in sight. The nearest forest is only a few meters away from the road. Sitting in the car, you can see through the darkness. trees, and saw the shrubs, vines, and countless unknown flowers growing randomly inside. "During the counter-encirclement and suppression campaign, we penetrated behind enemy lines and passed through this valley, and rested here for a night." The driver had participated in the counter-encirclement and suppression campaign. While driving, he vividly described to them how they passed through the virgin forest and penetrated into the enemy's rear. Behind enemy lines, they pointed to the faint fluorescent light in the forest, indicating that it was the light paint they sprayed on the tree trunks to guide the troops forward. The experts in the car looked in the direction of his finger and could only see a little bit of light that appeared or disappeared through the tree trunks, branches and leaves, and they didn't know whether what he said was true or false. However, since everyone had no actual experience in field marching or combat, they naturally listened with great interest, nodded and praised in admiration. The road is winding. Because it is blocked by the saddle-shaped mountain range, it first goes north, and after bypassing this small mountain range, it turns southeast, travels three or four kilometers, and finally turns north and enters the mouth of the valley. This valley is still very wide. The mountain at the entrance is gentle, about six or seven hundred meters wide. Looking from the front, the narrowest part is about two or three hundred meters long. The terrain is very broad. The soil in the valley is washed down from the mountains on both sides and accumulated over the years. The ground is very flat. As long as drainage is done well, it is a good place to build a town. It¡¯s just that the soil quality here is very poor, it¡¯s all red soil without organic matter. Judging from the fact that there are no traces of human beings and no houses or fields here, it is indeed a deserted land with no human settlement. As soon as the convoy turned around the foot of a mountain, it heard the continuous sound of firecrackers ahead. A huge sound rippled through the valley, overlapping with an unknown number of explosions, billowing like muffled thunder. "Don't be nervous, everyone, we are blasting the mountain to dig caves for the future military industry." The companion who accompanied the car stood in the aisle and comforted. The experts in the base area have never been engaged in military industry before, and may not be used to it. These domestic experts are veteran military industry experts, so naturally they are not unfamiliar with this. Instead of being frightened, they went to the window and looked out. ??????????????????????????????????????????????????????: Engineer soldiers wearing blue canvas overalls are everywhere in the winding valley. It is initially estimated that there are no less than two to three thousand people. They were divided into dozens of teams and were drilling holes between the left and right mountain walls to fire off cannons. They then used excavators and forklifts to dig out the broken stones, and then used drills with drill bits to peel off the surrounding loose rocks piece by piece. Expand the blasted hole. When the drill bit no longer touches loose rocks, the drill no longer digs slowly, but withdraws, and the engineers come forward to drill holes again and place explosives for the next directional blasting. Through continuous blasting and the assistance of various engineering tools, the hole was quickly expanded to ten meters square, and then quickly extended in depth. ¡°We have started excavation work here since the beginning of the year and have already excavatedThere are more than 20 large caves two meters wide and ten meters high. These caves are dug straight forward, almost two hundred meters deep into the mountain, and then a main road is dug laterally. Then, using this main road, we continued to dig caves into the heart of the mountain, which were used as living and working places such as workshops, dormitories, warehouses, and research institutes. On top of these main roads, many branch roads have been excavated to connect up, down, left and right. "The companion stood behind the driver and introduced to the experts. Domestic experts smiled and nodded slightly. Excavation of tunnels is not unfamiliar to China and is a common occurrence. Facing the threat of giant bears in the north, domestic experts But there is no shortage of tunnels to dig. They are dug where there are mountains and where there are no mountains. In the mountains in the southwestern part of the country, there are tunnels stretching for tens or hundreds of kilometers, not to mention several kilometers. It¡¯s not uncommon. ¡°Dig a hole deep, store up a lot of food, and prepare for a war, a big war, a nuclear war!¡± " This kind of propaganda slogan was often shouted in the past few years. Anyone who came from that era is familiar with it. Whenever the situation is tense, some key experts have been suddenly removed from work by security personnel. When called to work, I didn¡¯t even have time to get a change of clothes, so I hurried to the airport or the station to meet up, and took a plane or train straight to a hidden hiding spot in the mountains. This happened more than once. Although this is done less often now, in China, the situation in the north is still very low. Their vigilance has not relaxed at all. The mountain project built in the base area is just a replica of the domestic one, but on a smaller scale. They look out from the car window and can easily distinguish the mountain walls based on their own experience. There are densely packed holes, which are ventilation holes in the tunnel group, which are skylights, and which are emergency escape doors. From the layout and construction methods of these tunnels, it can be seen that they have received technical guidance from the domestic engineering troops. The higher the completion rate of the excavated caves, the louder the explosions will become. ¡°We started from the end of the valley first so that we can arrange the defense system and place the more sensitive projects in the safest locations. "The escort explained. The convoy finally stopped at the end of the valley. "It is said to be the end of the valley, but in fact there is a smaller valley road, which extends forward in a winding way and does not know where it leads. "There are many small branch valleys that go through there. We Turn it into an outdoor testing ground. Some artillery experiments or more dangerous experimental projects are carried out in those small valleys to ensure safety and no serious casualties will be caused in the event of an accident. "The companion saw their eyes and explained. "It turned out to be an outdoor test site." The experts nodded. They could see that there were soldiers hidden in the surrounding mountains and valleys. These were not engineers wearing blue overalls, but a Soldiers wearing digital camouflage, helmets and body armor, and armed with live ammunition, are scattered in groups at the commanding heights of the surrounding mountains. Two teams of sentries with military dogs can also be seen patrolling the dense forests on the mountain ridges. Looking closely at the reflection, you can see the iconic trumpet-shaped muzzles of the anti-aircraft guns. They are safe, very safe! Look further. The location where the convoy is parked is in front of a large cave on the left. The cave is twenty meters wide and ten meters high. Not to mention ordinary vehicles, even shooting vehicles carrying special equipment can enter and exit. It¡¯s easy to get in and out quickly. The entrance to the cave has been repainted with cement, but the outside has been painted with the same red color as the surrounding mountains as a camouflage. A large tree with lush branches and trunks has been specially transplanted on the hillside above the cave entrance. The branches and leaves that came out covered the top of the hole like a big umbrella to prevent the target from being detected by the air. At this moment, two huge steel doors sealed the entrance tightly, leaving no gaps. The second jeep door opened. Guan Fei got off the car, walked to the gate, opened a heavy steel shell, and entered a line of numbers on the code plate. Above the cave, a camera probe became active, turning left and right, scanning the fleet front and back. , and then reset. A few seconds later, a rumble sounded like it came from the ground. The two steel doors slowly moved away, revealing the passage. The car in front started and drove slowly into the cave. , the cars behind came in one after another. When the last car passed, the steel door roared and closed again. "It is at least two meters thick, and from the cross-section, it is not just pure steel. , and there are ceramic plates, fiberglass and other things sandwiched in the middle. It is simply thick.??Composite armor! " "How high the penetration power is to be able to penetrate it! " The experts were discussing quietly, but this time the people's army accompanying them did not introduce themselves, just smiled and said nothing. " After the bus the experts took passed through the gate, they found that the passage inside was very wide, and two rows of incandescent lamps were installed on the top. The lights illuminated the passage as bright as day, and the car did not feel dark and narrow at all when driving in. Moreover, they found several holes like shooting holes on the mountain walls on both sides, revealing several machine guns. The muzzle of the gun was slowly turning with the convoy, and it could be judged that someone was operating behind it. If it was an enemy coming in, it would have been rained down by bullets from high places on both sides. The convoy traveled about fifty meters. He was stopped by the second steel gate again. Guan Fei also got out of the car, opened the thick steel shell on the panel, and entered the password, but this time he also verified his fingerprints and pupils, and then the second steel gate opened. "Good guy, with the protection of these two steel gates, even a nuclear bomb can't open it! "An expert chuckled. Several experts in the car who had been to third-line security units smiled and said nothing. "Two steel gates are nothing, we have seen three or more! Some of the more important national defense tunnels even have holes on the top. Multiple layers of steel plates have been installed for reinforcement. Not to mention that ordinary aerial bombing can't do anything about it. Even if it is bombed with nuclear bombs, it can't be blasted. This is a genuine national defense project.
