After a while, Erhei took back a cloth pocket, the pocket is what Cheng Yang commonly uses, Cheng Yang four people divide labor, Yun Haifeng Erhei is making a bracket, Cheng Yang and Zhou Luqiu are digging a groove, after all, this kind of collapsed place is to use a support to support the top surface, so when digging, the bracket should also be put in, if the bracket is not done well, the hole will collapse, and if it is not dug well, it will also collapse.

Cheng Yang and Lu Qiu had already dug out an opening that was enough to place the scaffold, as long as the scaffold could get in, it would be considered half the success, and nearly half an hour had passed since the collapse.

Erhei walked to the hole dug by Cheng Yang with a stack of wood, and put the wood at the front into it, and then Cheng Yang and the four of them began to rotate the wood clockwise, and the wood went in quickly, and after a while, he felt that the resistance in front of him suddenly disappeared, Cheng Yang knew that he had figured it out, and Cheng Yang also had a rough distance in his heart to know how long it was here.

In fact, it is not very long here, and if you dig it fast, it only takes a dozen minutes to dig through. Cheng Yang began to dig up after assembling the shelf, Cheng Yang dug a more classic way of digging a square hole, in this case, you can't dig a round hole, because there is no place to put a bracket inside the round hole.

It took a total of an hour for Cheng Yang to open the passage, and there was no one on the other side of the cave, so he just used the walkie-talkie to call the people inside. Soon the people inside had a weaker reply. Because there is no oxygen in the cave, oxygen has always been supplied by an oxygen machine, and after the collapse of this place, there was no new oxygen coming in, so the oxygen that could be used was quickly insufficient.

The oxygen supply machine soon continued to supply oxygen to the inside, and the workers who stayed on it also came down to help clean up the other parts of the passage, after all, Cheng Yang had already dug a temporary passage, so there was no need to worry too much about the oxygen problem of the people inside.

Because there are more people, this place will be emptied soon, and the program will come over after Cheng Yang has been completed, and say thank you to this Cheng Yang, after all, if something happens here, he is the first person to be responsible.

Cheng Yang went in because he was going to go in to see why the ground couldn't be blown up, and when Cheng Yang went in, he happened to see the people inside being helped out by someone, because the wires had been reconnected, and it was very bright inside, so Cheng Yang nodded to them.

At this time, Erhei walked over, handed the bag in his hand to Cheng Yang and said: "Yun Haifeng saw that you didn't take anything, so let me send it to you, and said that there might be a serial cave inside, so be careful." ”

Cheng Yang took the thing and looked at it, a multi-functional knife, a shovel, a strong flashlight and a walkie-talkie. Cheng Yang patted Erhei's shoulder and continued to walk inside.

Walking in it alone actually felt a little lonely, but Lu Qiu was not interested in everything, so Cheng Yang didn't ask him to come along.

After walking for a while, he saw that there were many tools for explosives on the ground, as well as explosives placed on the side, Cheng Yang took a look at these explosives and the energy released was much smaller than the explosives that usually blew up holes.

Looking ahead, I don't know if it was because it was blown up or because there was no wiring, Cheng Yang turned on the flashlight and looked at it, and there was a dead end not far ahead. Cheng Yang took a look at how their explosion points were arranged, and when he saw Cheng Yang, he understood that this group of people was blown up by the usual blasting method, and this kind of cave was designed to be bombed, so the general cave has an explosion-proof function.

Cheng Yang pressed the walkie-talkie and told Yun Haifeng about the situation, and at this time, a man with a white hat came over, pointed at Cheng Yang and said, "Who are you and why are you here, don't you know that outsiders like you didn't come in here, Tu Lao Hat." ”

Cheng Yang looked at the other party with some disdain, thinking to himself who this guy is, Cheng Yang doesn't know him at all, and why is he still holding it like this. I asked, "Who are you?" ”

The person on the other side said angrily: "I am the engineer invited here, who are you?" ”

"Is the engineer you invited very good? You don't need to know if I'm you, I've opened the passage, you just came, and the person who was trapped inside just now when you came would have already died. ”

The person standing opposite Cheng Yang was still the same, and Cheng Yang didn't bother to talk to the other party, after all, the old man said that let Cheng Yang follow up on the matter here, and it was considered a test.

Cheng Yang was holding the explosives in his hand, after all, they had already made a hole, but they didn't explode it, so Cheng Yang is now readjusting the proportion of explosives, and strive to blow up here in one go.

Cheng Yang looked at the person after he got it, the person was far away from Cheng Yang and kept talking about something with the walkie-talkie, Cheng Yang saw that the other party didn't look at him, so Cheng Yang pressed the explosive and the detonator.

Because the explosives were stronger than the original explosives, Cheng Yang could feel that the entire ground was shaking, and the sound was very loud. There was already dust flying everywhere around, Cheng Yang's flashlight could barely see the ground around him, Cheng Yang covered his mouth and looked at the place where it had just been blown up, the ground was no longer there, and the ground was already a hollow.

Cheng Yang's walkie-talkie suddenly remembered Yun Haifeng's voice, Cheng Yang covered his mouth and responded to the other party: "It's exploded, you came in with something vacuumed, and water, my face is covered with dirt." ”

Soon Lu Qiu came with a relatively large vacuum cleaner, and the dust was quickly cleaned, Cheng Yang looked at the engineer in surprise, and almost laughed to death.

A person who is covered in ash and has a big mouth poked where, the funny thing is his posture, he actually leaned against the wall with one foot and his body, the independent posture of the golden rooster makes people want to laugh when they look at it.

Erhei and Lu Qiu were already hugging each other and laughing, holding tears while laughing. Yun Haifeng and the program looked at the engineer with some sadness, and soon the engineer was pulled out by the workers. The program took a look at the hole in the ground, shone it with a flashlight and said: "It seems that the underground space is quite large, put ropes and ladders, go and get the pathfinder we use, and use the mechanical pathfinder, it will be much safer." ”

Soon the machine car was put down, and from the picture transmitted back, the complexity of the underground can be imagined, and then the screen suddenly blurred, and it must have been the mechanism that damaged the machine car.

Lu Qiu saw that he was already a little nervous, and Cheng Yang was actually a little excited in his heart, so he said to this program: "Lu Qiu and I will go down to take a look, first make sure that the neighborhood is safe, and then you will come down." ”

After speaking, Cheng Yang and Lu Qiu slid down the rope, but before Cheng Yang slipped to the bottom, the top of the cave was frightened.

"I'm Nima, what the hell is this, it's scary." Lu Qiu grabbed the rope and said.

Cheng Yang was also shocked, what kind of thing is this, there are snake heads on the top of the cave. Soon Cheng Yang and Lu Qiu fell on the ground underground, Cheng Yang stood on the ground and looked around, although he had just seen the surrounding scene in the transmitted screen, but Cheng Yang was still a little surprised by the surrounding scene.
