The latest website: Once the inside collapses, it cannot be pulled out at all.

Yan Ming originally wanted to explain a few words, but seeing Qin Yuan's insistence, he didn't want to say anything, he could only pray for his safe return.

Qin Yuan has already made preparations. Even if he flips over, it will not be a big problem. He can hold his breath for a long time in the water, even if he is down there, it will not be a problem. In addition to his own recovery ability, there are all kinds of problems. Protection measures, absolutely not a problem.

When he really entered the mine, he could hear the sound outside at first, but he could only hear his own breathing in the back. Yan Ming also prepared a gas mask for him, mainly because he was worried that there were other harmful substances in the mine. Qin Yuan took off the gas mask.

It was not a big problem for him here. At first he was able to stand upright and come in, but later he could only bend over. He found a few weak places and began to put on the support frame.

He walked like this while padding the support frame, and when he got inside, he found that it was not worth his waist at all. The whole person was completely half-prone, and he began to dig into it here.

Qin Yuan's excavation speed was very fast, and the repairs were also perfect. He quickly opened up the mine completely, and he was carrying a testing instrument on his back.

The key to affecting the speed is that he has to stop from time to time to look at the ore situation below.

In this way, he used the support frame to support each tribe point while going down. He knew the structure here very well. Even if the soil here was loose, as long as he did the preliminary work well, it would basically not be a problem.

However, only Qin Yuan can do this. He Chenguang and the others who were outside slowly noticed that the safety rope on their hands had moved a few times. Everyone tensed their nerves and stared at the safety rope tightly. There was a strong pulling force, and everyone was very nervous, so they could only pull it out desperately.

He Chenguang and the others thought that Qin Yuan was short of oxygen inside, after all, anything could happen in this situation.

It's just that after everyone pulled it out, they found that one basket after another, soil was constantly being transported from it.

And they only need to be responsible for pulling out the baskets outside. These baskets are also left over from the previous batch of excavation teams, and they dare not dig deeper.

In this way, he continued to dig for more than an hour. Yan Ming next to him couldn't believe it~www.mtlnovel.com~ Just relying on Qin Yuan alone, his digging speed was so fast.

In a short period of time, a hill will be formed next to it, which is too exaggerated! After more than ten minutes, no soil was brought out again, mainly because the supporting frame in Qin Yuan's hand had been completely used up, and he had to bring in the supporting frame from the outside.

As the depth continued to deepen, he originally wanted to use the walkie-talkie to let them send him in directly from the outside, but he couldn't get in touch at all. In the end, he could only crawl out from the passage.

As soon as he came out, Yan Ming and the others quickly gathered around to check the situation. Qin Yuan only had some dirt on his body and head, but he seemed to be in a very good spirit.

You must know that this is the first time to enter such a deep place, and the safety rope is no longer enough.

"Captain Qin, I didn't expect you to actually do it, and your speed is too fast, you just dug so fast by yourself."

"What is this? It's just that there is no support frame!"
