The firefighting display with the equipment in place fixed the safety rope and slowly climbed down the cave wall. But a few minutes later, the person with the walkie-talkie on the ground suddenly became nervous and shouted loudly. There seems to be no response on the other side of the intercom. Three or four people hurriedly pulled the safety rope, but it felt very light when they pulled it, and when they pulled the rope up, they were sure that the person was gone. A section of the rope appears to have been ripped off as well. According to common sense, the safety ropes used by the fire brigade are very tough, and there is no problem at all in carrying a person. How can it be broken? Could it be that there is something wrong with the rope. Then they organized another rescue operation, this time two people went down from the left and right sides, but strange things happened again. Or the same position, the same result. The rope broke again.

This made a few leaders anxious, and they suddenly had no idea. Because no one can guarantee that those who are sent down will not be in danger again. But if no one goes down, how can the rescue operation be carried out? Time passed minute by minute, and the people who watched the excitement probably felt that things were a little unusual, and they were afraid of harming the pond fish, so they quickly ran away. Now I'm the only unofficial person here. One of the policemen looked at me and said, "Why aren't you leaving?" I replied, "I want to go down and see." "Which policeman was surprised and quickly reported to the leadership.

A man walked up to me and said, "Hello comrade, I am Cao Yang, the director of the Municipal Public Security Bureau. I replied: "Hello, my name is Liu Shengtian." He said, "I heard you want to go down?" Why? I didn't know why, so I casually said, "I'm afraid they won't be able to go down." He laughed, and then said, "Why are you so confident, you will definitely come up if you go down." "I said believe it or not, and turned around to leave. He quickly stopped me and said, "Wait, wait." I'll debrief. After saying that, he turned around and made a phone call. It may be that the situation here was explained to the superiors. Then he turned around and told me, "I have already asked my superiors about your matter, but there is nothing I can do because the situation is urgent." However, it is important to ensure your personal safety. So I think I'd better find a few people to go down with you. "I thought about it, but I forgot it. When there are too many people, it is easy to have accidents. In the end, I promised that there would be no danger, and he agreed to let me go down alone.

A couple of people came over to help me get my gear on. There's a headlamp, and there's an equipment bag, which is full of some caving professional stuff and necessities, such as pencils and A4 paper. Something like that. Glowsticks, batteries, flares, lighters, candles, compasses, markers, chalk, self-spray paint, first aid kits, and flashlights are all essential. But it's really heavy on the back. Not only this, but also an oxygen cylinder, because I don't know the composition of the air below, I am afraid that it will be toxic or the oxygen content is low.

Gear up and fasten the safety rope. Climb slowly down the pit wall. The upper side kept asking about the situation on the intercom. It took more than half an hour to go down to about five or six hundred meters. Later, I couldn't climb anymore. I reported the situation above, and I probably didn't expect it to be so deep at the time. Someone on the ground pulled me up slowly. Therefore, it saves more effort and time than going down. After about ten minutes, I climbed out of the big pit. As soon as I climbed out of the ground, a red sports car drove up nearby, and a young woman got out of the car and yelled as soon as she got out of the car. Hearing that she meant that her own brother also fell into this big pit, clamoring to save people quickly, several firefighters were overwhelmed by her for a while, and they had to be leaders. There was a loud shout and three of us were in distress during the rescue process. It's not saved yet, you're in a hurry, you're in a hurry to go down and save yourself. After saying that, he turned around and left. The girl was stunned on the spot, speechless. At this time, many family members of those in distress arrived one after another. They all asked to save people quickly, and several policemen explained the situation while doing enlightenment work.
