The four of them crawled to the outside of the cave, because they were afraid of the swarm of poisonous bees on their heads. Ma Qian climbed in front, but as soon as his foot kicked, he fell into it in one fell swoop, what was going on? Ma Qian was a little hairy, and he didn't know what danger was waiting for everyone. He instinctively said "Huh", and wanted to pull out the fallen leg, but as soon as he tried hard, the leg came out, but it brought out a large ball of dirt, which was all pasted on the face of Zhao Baixiong behind him.

"I'm going, what are you doing, what is this!" The unlucky Zhao Baixiong was a little unhappy, he didn't understand how Ma Qian kicked out a large cloud of dirt as soon as he kicked his feet.

"Dirt, how can there be mud in this stone cave" Lao Niu was very alert, he immediately realized that the situation here was not right, he felt on the ground, and soon touched the pit where Ma Qian's legs fell. This is a pit that has been filled with earth, how can there be a pit in the cave?

Lao Niu turned on the flashlight and shone it on the ground, turning the light of the flashlight to the lowest, for fear that the light would attract the poisonous bees overhead, because the poisonous bees were still unstable, still "buzzing" on the heads of the four people.

Ma Qian and Zhao Qingmai were also attracted by the flashlight of the cow, it is really strange to think about it, the whole cave is opened on the stone, there is a loess pit under this poisonous honeycomb, and the loess in this pit is very soft, Ma Qian just kicked lightly, and he fell down.

This is a small pit with a diameter of thirty centimeters, I don't know how deep, and it was stepped on by Ma Qian just now. Zhao Qingmai took out the sapper shovel behind his back and dug it up gently, his movements were very light, for fear of triggering the mechanism inside. The loess was cleaned out little by little, and when it was about half a meter deep, the sapper shovel "banged" and touched a metal. The sound of metals colliding with each other is crisp, creating an echo inside the hole, sharp and harsh.

Several people were lying on the ground, for fear that the sapper shovel had touched the mine, and planting the mine on the ground was a common ambush method used by the Japanese army in those years. The four of them waited for a moment, and without any movement, they gathered again, and at the bottom of the pit, a metal disc was exposed. It was a shiny round object, as if it were made of stainless steel, and it had been buried in the soil for an unknown amount of time, and it was still shiny without a trace of rust.

What the hell is this thing? The four of them looked at each other, all of them at a loss. Zhao Qingmai took the lead in reaching down with his hand and erasing all the soil on the round metal plate, revealing a round plate. Lao Niu carefully touched the metal disc with his hands, cool and slippery. The disc is more than 20 centimeters in diameter and about 3 centimeters thick. Lao Niu grabbed the disc with his hand and pulled it, it was very strong, and he used a little more strength, but the disc still didn't move.

Zhao Baixiong stretched out his head, and he asked, "Burmese boy, does this thing grow on the ground?" ”

Lao Niu shook his head and said, "This thing is very strong, it was installed here by someone's story, and the soil on it is obviously a camouflage."

Zhao Baixiong stretched out his hand, and he also pulled the metal disc, but he didn't move at all. The guy's strength came up, and he shook the disc vigorously, and the disc moved in a clockwise direction. "Hey, this thing is a spiral, it can be turned."

Zhao Baixiong shook it with brute force, and unexpectedly found that this disc-shaped metal could be rotated. Zhao Baixiong was very excited, and he used his hands to alternately rotate the metal disc in this pit. The resistance was greater at the beginning, but after a dozen or so turns, the resistance became smaller and smaller. Everyone is looking forward to it, I don't know what is under this disc, it can't be any treasure.

Soon the resistance was completely gone, and it looked like the thing had been completely unscrewed. Zhao Baixiong lifted his hands upwards vigorously, he wanted to lift the metal plate to see what was underneath. Under this metal disc turned out to be a metal piston body, and this piston was pulled up by Zhao Baixiong. Just when it was pulled out more than 20 centimeters, there was resistance again, Zhao Baixiong made a lot of effort, and the force was not small, but the metal piston was not pulled out, but there was a "boom" sound. Ma Qian felt that the voice was very wrong, as if the ground was about to crack. Before he could listen to the sound, his body sank and fell.

Ma Qian's body was completely weightless, and he fell into a space at once, and fell heavily on the ground with a snap, and before he could sit firmly, another person fell down and smashed on Ma Qian's back. He endured the pain and tried to touch it to see if it was hurt, but he slipped under his ass and rushed out, instinctively trying to grab something, but he was surrounded by smooth metal and couldn't grasp anything. It was like riding a roller coaster, the wind was whistling in my ears, and I couldn't control my body at all, so I could only lie down and slide quickly. During this time, Ma Qian heard the heavy breathing sound around him, and he could also hear someone shouting "ahhhhhhhh

In the darkness, I don't know what this place is, what kind of device makes people completely lose their center of gravity and glide quickly. I don't know how many meters I slid downward, Ma Qian slammed into a person's body, that person said "Mom", it was Zhao Baixiong again, he stopped first, and Ma Qian bumped into him. Then another person crashed into Ma Qian's body, it was Zhao Qingmai, and the last one who slipped over was Lao Niu, and the four brothers reunited in the dark unknown world.

Lao Niu was the first to turn on the light, it was the wolf's eye flashlight, this high-intensity flashlight illuminated this mysterious space at once. After the four of them adapted to the light, they were completely stunned, what is this place, where is this like being in a cave, this is obviously in a sophisticated instrument and equipment, around them, there are closely connected metal parts, a space of nearly twenty square meters, all enclosed.

Ma Qian said in surprise: "This seems to be a space warehouse!" Have we crossed over to a space station in the universe?"

He was originally a nonsensical joke, but no one laughed, and even everyone didn't even have an expression on their faces, because they were completely confused, what the hell is this place, why is it so peculiar.

Zhao Qingmai knocked on the metal parts around with the butt of the gun, the sound was very brittle, it seems that this is a kind of metal, I don't know what era it was built, looking at the solidity of the surroundings, this thing is one.

It was discovered that there were some metal balls around the large instrument, and there were some remnants of stone powder on the metal balls. It's a flat cylinder, and you're on the inside of it. At each end of this long cylinder, there is an exit, and everyone just slipped in through one of the exits. The exit at the other end is closed, and the closure is kind of like the exit of a submarine, a kind of moving spiral, now tightly closed.

After Zhao Baixiong saw this strange metal space, he exclaimed: "This should be a metal cage, we were caught by ghosts, they see, there is only one exit left, and we were pushed down by a strange force, you say, what is this not a ghost?" ”

"Zhao Baixiong, don't talk nonsense, what the hell, what a god, this is an industrial equipment, there is this kind of equipment in modern mines, it is used to crush ore, this kind of thing is scientifically called 'ball mill', we fell into this machine. The port we fell into was the inlet, and the average worker slipped the ore into the machine through a slide. Then this 'ball mill' rotates quickly, and the metal balls on both sides will crush the ore, and then open the outlet, and pour the ore out, and the outlet that is closed now is the outlet, which I have seen in a certain mine." Ma Qian actually knew what this strange machine was, and it still startled the others.

Just now, Zhao Baixiong accidentally activated a certain device, and the four people fell down like an ore that had been dumped, and then slid along the track of the ore and slid to the inside of this 'ball mill', if this 'ball mill' was started and running now, the four people would be ground into meat puree in an instant.

Fortunately, now the machine is not moving, or it hasn't moved in decades.

Lao Niu said: "This should be the equipment of the P7 base back then, I didn't expect that the Japanese had such advanced equipment in that era, this should be the machine that crushed gold ore back then." I didn't know what kind of equipment or workshop it would be when this exit went down, but we stumbled into it and fell into the interior of the refinery."

This is the internal equipment of the refinery, God help us, it turns out that it takes no effort to get it, it is so easy!
