And those underground people who ran in front also knew this. They all relaxed their hands and feet and crawled quickly on it.

Lying on the ground, I picked up a layer of floating ash with my hands. I saw a bright layer of things below through the headlamp. It was a bit like glass with poor transparency and strong reflective ability. However, it didn't reflect light. I didn't care. The key was that after tapping a few times with my hands, my heart suddenly hung up like the two bridges hanging high above the lava river, The thin layer of this thing, the knocking feel and sound tell me that it is empty below.

Seeing several of us studying the ground there, the Nightingale who followed Andre and others came up to us and said, "it's Muscovite rock. If you don't want to die, take it easy."

"What?" Ivan asked in wonder. The nightingale did not answer him. She thought she was still angry that Ivan had just called these underground people "monsters". Seeing her turn her face to one side, I had to repeat Ivan's question and tell her that so far we are not enemies. The real enemy is fluttering a pair of colored wings and commanding a large group of self exploding zombies to chase us.

"Muscovite rock layer is a plate-like rock layer composed of muscovite and hexagonal crystals. It is characterized by being thin, about more than ten centimeters thick, and is formed after the surface material of acid magma cools. Generally, during plate movement, the surface cools after magma upwelling, and the high-temperature lava at the bottom flows away through other channels. After the magma height drops, this layer covered by mica rock layer will be formed I basically understand the words of the Nightingale "cavity", that is, we stand on a piece of weak glass.

"What do you mean? Under our feet, across this layer of things, is..." I asked. Later, my tone shook up, joking, walking on the magma. Who is not afraid.

"Yes, this is our final defense method. The places you passed just now have similar composition, but they are all used to deal with the Soviets.

In fact, you don't have to be afraid. Maybe the magma below has cooled down, "said the Nightingale, pointing to the stone bridges we just passed behind us, and then trying to comfort me.

But everyone knows whether she said this or not. Judging from the several stone bridges she just passed, I'm afraid it's thousands of kilometers away from the magma below, and what's the magma cooling? Even if I don't know geology, I know it's rock. In other words, if you fall, you will either fall into the boiling magma and burn it into ash, or fall on the hard magmatic rock and turn it into meat cakes. Now, the wisest way is not to step on the layer under your feet.

Just when we wanted to start climbing, we saw a light flashing along with the running. Sanmei looked at it for a few eyes and said, "it's a blood dragon."

Closer, we saw that it was the blood dragon who just led the team to leave and ran back with more than 50 underground people. The difference is that nearly 40 of them are carrying a shell.

"Eh? Where did it come from?" at the same time, I thought of the answer to the question. They must have returned to T62 sandwiched in the rock crack and used the excellent climbing ability of these underground people to take out all the shells in the tank. Since we robbed a tank to escape, we mainly used anti-aircraft and parallel machine guns to deal with zombies. We only fired two guns.

The ammunition base of T62 is 40 rounds, and the normal ratio is grenade 17, shelling armor piercing projectile 13 and armor piercing projectile 10. In addition to the two rounds we used, the other 38 were here. They carried a lot of them all the way. They really have strength with more than 60 kilograms of things.

The key question is, what are they going to do after all? Blow up those zombies? Even if these shells are used, they will blow up hundreds at most, which is nothing to those self exploding zombies in 10000 units. Dealing with queen Yan? That's even more impossible. Let alone only shells. Even if we were given a 115mm shotgun, we couldn't pay for the flying monster.

Ivan was impatient and didn't bother to think like me. He opened his mouth and asked the blood dragon, "what are you doing carrying these things“

The blood dragon glanced at Ivan and us with his usual empty eyes and said four words briefly: "die together." while he said these words, the hatred in his eyes told us that this guy was serious.

After meeting the last batch of underground people carrying shells, we scattered and began to crawl on the thin mica rock layer, and our hands and feet touched it at the same time. The feeling of fear was more obvious, because the hands would feel the frightening creak caused by extrusion. It seemed to tell me seriously that with a little force, it would break, and I would fall under the abyss, knot Fruit? Naturally, it's a choice between meat pie and black ash.

Fortunately, this situation did not occur, or the mica rock here was reinforced by those underground people. In short, although it was creaking all the time, it still persisted until we safely reached the lower part of the flat topped Jin'an tower. This is not the coverage of those mica rocks, but the real rock stratum, otherwise it is impossible to support a six story gold tower Word tower.

After reaching the foot of the pyramid, several of us with guns immediately opened the defense line, but Andre told us not to. Just stare at the sky and don't let Yan Hou fly over. At the same time, several young underground people with shells on their backs and serious ares walked in through a side door at the bottom of the pyramid, and there were underground people operating something at the top of the tower.

Because we are faster than those zombies, we have won a certain buffer time. The slow figure of those zombies has not appeared yet. Ares has come out of the pyramid with a black box. Followed by a few underground people who walk shakily. Judging from the piles of wrinkles on their faces, they are probably older than the one who was responsible for keeping the kindling just now.

"Where were those guys just now?" I asked Ares. I was stunned as soon as I finished, because I saw several people behind ares wrapped with ropes, just the kind used to carry shells. In other words, a few young people who just entered the tower - instantly aged dozens of years

As soon as Andre and the Nightingale saw the black box engraved with hieroglyphs, tears gushed out of their eyes, and even a trace of deep sadness passed through the empty eyes of the blood dragon. I realized that what is contained here is probably what they mentioned just now. We must grab what we get in front of empress Yan. Thinking of this, I couldn't help being interested in this black box that could hold the size of a football. At the same time, I realized that it was in this box that the essence of several underground people was instantly drained away, which made them grow old in a short time. It was as if ares had changed his name to Pandora.

What the hell is in here? I want to step forward and look at the box carefully. Who knows, as soon as I stepped out, I immediately put an AK muzzle on my back. As soon as I turned back, I met the blood dragon, who had recovered his empty eyes. It seemed that this guy was ready to kill me.

My companion immediately picked up his gun, but this time he didn't fall into that confrontation again. First, Ares and I asked our companions to put down their guns; The second and most important reason is that the zombies followed.

When a large number of zombies came to the mica rock layer, there was a rattle of gear rotation at the top of the tower, as well as a dull sound of collision. A stone half the size of a refrigerator was bounced out by a launcher powered by air pressure. From the perspective of launching, the stone did not intend to fly far, but as high as possible.

After drawing a very narrow and high parabola, the stone rushed to the ground with gravitational acceleration. First there was a click, just like falling on the lake in Northeast winter. Half of the stone smashed the mica rock layer, revealing only the upper half stuck there. Then, taking the stone that hit the rock stratum as the center of the circle, patches of mica cracked and fell one after another. The whole large area larger than the football field, with a point as the center, produced radioactive cracking, and countless stone core zombies fell down with broken flakes.

After the whole mica layer was broken, a large abyss had been created between the flat topped pyramid and those stone core zombies, and under the abyss were those high-temperature magma flowing. In other words, in addition to self explosion, they have to fly to come over.

I ventured to the edge of the abyss, looked down, and saw the color like a steel furnace. The zombies became smaller and smaller, fell into the running red, and the "waves" that stirred up magma were quietly melted in it. After each zombie fell, bright dots would appear and disappear in a flash, I know where their bodies are burning.

I turned my head, pretending to be humorous and said to my companions, "fortunately, it was not us who drowned in the coke." unexpectedly, they ignored me, but very neatly picked up their guns and aimed at them at an angle of 45 degrees.

I immediately turned around and put on the sniper rifle I had just taken in the gun room. I saw empress Yan hovering over the abyss from a distance. She didn't even look at the stone core zombies that fell under the abyss and burned in the magma like dumplings. Instead, she stared at the box in ares's hand and said in a loud voice, "give it to me and I'll let you live." Her words were over, and the echo was still floating in the underground space. It seemed that many people were persuading ares to hand over his things.

"What should I do?" Ivan turned and looked at me with questioning eyes. I turned to Ares. He shook his head and said, "too many of our people have died at her hands."
