With my voice echoing in the cracks under the ground, my heart is getting heavier and heavier. Is something wrong with Sanmei? No, I have to find her. Even if she is seriously injured, it's a big deal to give her my blood.

"A pool of mud, I'm fine" Sanmei's voice suddenly came from a place not far from me.

"Where are you?" I immediately got excited, leaned out and looked down intermittently, but found that the voice came from my side.

"We're above your head, fool" the voice of our companion came from the radio again, but this time it was changed into the cold tone of Jinlihua.

Immediately lit the flashlight, pulled over the radio and shouted, "where?"

With the light from above, I also found the armored vehicle stuck in the stone crack, and I also know why they were above us. Their BMP2 armored vehicle was hit and flew out, so it was stuck horizontally, and the total length of the armored vehicle was more than 8 meters. But our tank fell off askew, that is, it was not stuck until the stone crack was more than three meters wide. Thanks to Ivan, the tank turned a corner, otherwise it might directly hit the armored vehicle that fell first, and several might be killed on the spot.

Seeing that they were all fine, I finally breathed a sigh. The problem now is how to meet them, and then find a way to go up or down.

The current situation is not optimistic. I took photos of the stone walls on both sides. They are very smooth and very difficult to climb. We don't have professional climbing tools now. The armored vehicle was stuck obliquely above us and had to be 10 floors down to reach the bottom of the stone crack. We were in such an embarrassing situation that we couldn't get up and down.

"Wait a minute, I'll find out if there's any rope." after that, I pulled the handrail with infantry welded on the tank body, climbed over and opened the toolbox on the right side behind the car, but I was disappointed to find that there were only some maintenance tools in it. At this time, Sanmei's voice came from the radio: "we have a covered camouflage net in our car."

"The net is useful, and we don't catch fish," Ivan muttered.

"I have a way. You go back to the tank and close the hatch first," urged Sanmei on the radio. Although I didn't know what she said, I immediately pulled the handrail back to the cockpit and closed the hatch from inside.

After closing the cabin door and notifying Sanmei them, a huge machine gun fire rang out in the middle of the crack. Listen carefully. It turned out that Jinlihua was operating the 30mm machine gun on the BMP2. For fear that the chamber temperature would be too high due to continuous shooting, Jinlihua controlled the firing speed and fired continuously.

"These two women are crazy?" Ivan asked me as he listened to the gunshot.

I shook my head and didn't speak. I thought these two women were stronger than iron bars. Our lords were crazy. They didn't have anything to do.

After the machine gun sounded for a while, we could hear a lot of gravel rolling down, and fist sized stones jingling on our T62 body, just like the next rain composed of gravel outside the tank.

In my mind, I simply calculated the positions of T62 and BMP2, as well as the width of the stone walls on both sides. Generally, I knew what the two women were doing. At the same time, I secretly admired Sanmei's intelligence. It was worthy of being a woman who came through the storm.

If we connect our T62 tank with their BMP2 armored personnel carrier in a straight line, it is an inclined line. Then take this line as an inclined edge. The line at the horizontal position of the armored vehicle and the line perpendicular to the point where the tank is located can just form a straight angle triangle. Jin Lihua is pounding the horizontal line with a large caliber machine gun at the moment, It extends to the top of our tank, and two rows of pits of different sizes are blasted with machine guns for hand grasp or pedal.

After I told Ivan what I thought, he opened his eyes and asked me, "what are they going to do after that? Slide down from the top. Although the stone wall is not completely vertical, the slope is not enough, and they will fall to death."

At this time, the voice of Jinlihua came from the radio: "there are no shells."

"Well, come out and shine a light on me." after a while, Sanmei's voice came along the wireless telex.

"Light up?" Ivan and I were confused, but we climbed out of the tank, turned the flashlight to the brightest light and gestured upward. Ivan and I saw a very amazing scene when my neck was sore.

In the light column of the high-power flashlight, we all see a vigorous figure, kicking and jumping on one side of the stone wall, jumping to the other side of the stone wall with the strength, and jumping back with the same action. In this way, we control the falling speed with the help of the stone wall.

Ivan raised his head, swallowed his saliva very loudly, and said to me, "my God, your wife, it's really..."

I also raised my head and looked at Sanmei's rapid jumping fall with fear. I shouted, "take away the electric light and don't shine on people. She couldn't see the position when she shook her eyes."

It was more than a dozen acrobatic jumps back and forth. Sanmei saw the position of the tank and jumped over, which was firmly held by Ivan and me.

"Come on, open this net and four people pull it up." three Mei couldn't care more. She opened the camouflage net tied up on her back and threw the three corners of the square net to me, Ivan and Andre.

The four of us pulled the net flat and sent a signal to the companions above. They slid down the stone wall one by one. We caught them with a net like firefighters. Fortunately, they didn't fall straight. Otherwise, even if we could catch them, I'm afraid they would hit the body of the tank, breaking their bones and tendons. Another awkward thing is that the four of us don't have much space at all. We all barely stand on the body of the tank. Thanks to Ivan and Andre, Sanmei and I have great strength, so we didn't fall together.

Ares and the blood dragon came down first. They also helped pull the net immediately. Behind them were the Nightingale and finally the golden pear holding Irina. Some of his companions got into the tank, and the rest sat on the erected body. They cut the camouflage net with a military knife and connected it to make a rope more than ten meters long, ready to hang people to a narrower place in the stone crack below.

The stone cracks below continue to close. After hanging down more than ten meters with a rope, the distance between the stone walls can be supported by hands and feet, which can also be used in the way called "chimney" wall climbing method in the army. After climbing horizontally along the bottom of the crack for a long time, we finally tossed into a large structural cave connected with the stone crack.

The cave is very spacious. There are many canine shaped bamboo shoot shaped stone columns hanging on it. There are some small pieces of water on the ground, like a node in a three-dimensional spider web. There are channels for people to walk down and down.

"My God, this is also natural?" Ivan asked the nightingale. The Nightingale was thoughtful, as if she hadn't heard Ivan's question. San Mei looked around with a flashlight and found many artificial construction traces such as steps to remind us to carry our guns.

From the time we sat on the "Sibuxiang" mine car all the way down the railway track, to the time when we cut through the power grid and broke into the underground nuclear test base of the "Mercury program" of the former Soviet Union, and then we drove tanks and armored vehicles to break through the mine array and fall into the underground crack, we have been going down. Although we can't know the current altitude, it must be terrible. In this way, the simple anti-G clothes we wear may not provide enough protection for our body, so we all chose the upward connecting channel, hoping to find a way back to the ground, and at least avoid the risk of blood vessel burst caused by huge pressure.

I opened the road with a gun and looked for a way out along the upward steps, but the more I walked, I found that the route became more and more chaotic. Here is a three-dimensional eight trigrams array of Zhuge and Wuhou, which is so complex that I may not be able to understand even if there are drawings. Compared with the caves where the Afghan guerrillas who make the U.S. special forces have a headache, it's as simple as a crossroads with traffic lights. I believe it's just like this to enlarge the ant nest 1000 times.

At the fork of the complex cave, there are many hieroglyphs carved on the stone wall. Unfortunately, we can't understand any of them. The Nightingale glances at them from time to time and looks very interested.

Just as we tried in vain to find a way through countless turns and bifurcations, the cave began to reverberate with a faint explosion. The sound should be the cave above us.

"Did empress Yan command the army of self exploding zombies to kill me? If I was stabbed by her tail pin, please be kind and break my body with a grenade. I don't want to drink Corinna's blood." Ivan's tone was full of fear.

Sanmei listened for a long time at a fork in the road, pointed to the hole on the right and said, "the voice is stronger here."

"Let's go the other two," Ivan said.

"No," I and Sanmei objected at the same time. After they looked at each other, I continued: "we fell down and were stuck. Those stone core zombies must have found a way around the crack, so they will be a step slower than us. If you want to go back, you may have to make an article from it."

Sanmei nodded to say that this was what she wanted to say, and others had no objection. We immediately chose the channel on the right and marched up along the explosion. As we continue to make progress, there are more and more signs of human activities. There are a lot of tools and statues made in unknown ages in many caves, including belly shaped ceramic bottles we are familiar with and reliefs with very similar styles.

After entering a large cave filled with human statues, the sound of explosion has become more and more clea
