The height from the wellhead to the surface of the water is thirteen meters, and according to the speed of 9.8 meters per second in free fall, I should have fallen into the water after more than a second, but after I jumped down, I realized that I was too naïve, I already had a slight fear of heights, and a strong sense of weightlessness made my time senses infinitely prolonged, as if it took half a lifetime to feel that my feet touched the water.

Before I could breathe a sigh of relief, the soles of my feet felt the touch of a stick-like object, and between the lightning and flint, I remembered the steel pipe that had fallen into the bottom of the well before, and my heart said that it should not be really such a back, right? Hao Jian's area is fine, why did Lao Tzu come down and skewer it directly?

Fortunately, the bottom of the steel pipe was not fixed, just when I was thinking nonsense, the steel pipe was forced to slide directly against the sole of my shoe, and then I entered the water all over my body, and the cold water temperature instantly woke me up, and my hands and feet floated to the surface with two flutters, and I was stunned by the scene in front of me as soon as I wiped the water off my face!

Earlier, I thought that the space at the bottom of the well should be about the same as the area of the wellhead, but I didn't expect that there was a huge cavity underneath!

I don't know how big it is, the nearest well wall is two or three meters above my head, and if there is no rope or something, it is estimated that it will be difficult for us to return from the same way.

"This Liu Yunsheng! I don't explain the situation below, how can we go up now? I looked at the two or three meters high well wall and muttered, and when I turned around, I saw Hao Jian floating two or three meters away, staring at me with anger on his face!

Fortunately, I had thought of my words before I jumped down, grinning apologetically, and a few dogs swam to Hao Jian's side and asked worriedly, "Are you okay?" Kiko is really! How can such a joke be made? ”

"Come less!" Hao Jianmeng waved his hand and lifted the water in my face: "If you hadn't discussed it, that little girl liar would dare to do such a poisonous thing to Lao Tzu?" ”

"Yes, yes, you are wise and powerful, and your courage is extraordinary, forgive her for not having the guts!" I blew a rainbow fart along with Hao Jian's words, and only then did I react after speaking, isn't this tantamount to admitting that there is a tacit understanding first?

Thanks to Hao Jianzheng's anger and didn't react, I didn't mention this stubble, paddling the water to the bottom of the wellhead, from this position I couldn't see Kiko's face, I could only see her flashlight dangling at the wellhead, I took out the flashlight wrapped in a plastic bag in advance, turned it on and blocked the light source with my hand and began to send signals to it.

"What are you doing? It's only been a moment since there was a code word? Hao Jianyou came over and looked at the wellhead above and asked.

"Some code words, just a few simple signals to her that we are in danger or something." I replied casually as I signaled.

Hao Jian wiped the water on his face: "I can understand reporting safety, what's the use of reporting danger?" Can she come down and save us? ”

"Uh...... She knew that there was danger, so she could go to the village and find someone to help! I was speechless for a while, pondering for a while before I came up with a reason that was not so, and as soon as I finished speaking, I heard a sound of water behind me, and when I turned around, I saw Liu Yunsheng swimming over.

Liu Yunsheng's iris is pure black, and it is even darker and a little crazy in this dim environment, he stepped on the water twice and stopped and said directly: "There is a dark passage below, the water surface boiled just now because the dark channel suddenly opened, and the well water poured into it produced a large number of bubbles, I went in and probed twenty meters before the end, which of you has a better lung capacity?" ”

Hao Jian and I glanced at each other, then looked at Liu Yunsheng at the same time and asked in unison, "You asked us to come down just to ask this?" ”

"Hmm."

"You're sick!" Hao Jian blew up at that time: "Can't you just shout and ask for this kind of thing!" Why do you have to let us come down! You can't handle it with lung capacity, you can't handle it so badly, so we two waste can get a fuck! ”

Hao Jian's angry roar echoed in the underground cavity, although I didn't speak, I also looked at Liu Yunsheng angrily, he did this really not authentically.

Liu Yunsheng was stunned by Hao Jian's yelling, and paused before continuing: "Different hydrological conditions will have an impact on the underwater performance of the same person, and factors such as water temperature are difficult to express clearly in words without professional measuring equipment, so I let you come down and experience it." ”

I was quite angry, but when I saw Liu Yunsheng's righteous appearance, I became a kind of depression that I didn't know where to sprinkle when I was angry, and then I heard Liu Yunsheng say lightly: "The water temperature here is too low, which will seriously affect your physical strength, let's go down and take a look first." ”

After saying that, Liu Yunsheng turned over and dived into the water, Hao Jian and I looked at each other and made a speechless expression, and then also turned over and dived.

Just now I was shivering when I was floating on the water, but after diving into the water, I felt a little warmer, the light of the flashlight spread out in the water through the plastic bag, illuminating a range of more than ten meters in front of me, Liu Yunsheng swam into the darkness in a flash on the edge of the light, it seems that he is already very familiar with the underground situation, and he can find the exact location without lighting.

Hao Jian was two or three meters to my left, I waved at him, and pointed in the direction where Liu Yunsheng left, and then the two of them swam diagonally down for nearly twenty meters, and I saw Liu Yunsheng reappear in the light range, and there was a dark stone wall in front of him, and a hole with a diameter of nearly one meter was opened on it.

Outside the entrance of the cave there was a palm-thick, rusty iron plate, one end of the thumb-thick iron chain was welded to the iron plate handle, and the other end extended down into the darkness, I used the flashlight to find it and didn't see the end, so I retracted my gaze and looked at Liu Yunsheng, gesturing to ask him what was going on.

Liu Yunsheng pointed to the iron plate, and then his two hands quickly played a series of sign language like a seal, Hao Jian and I looked confused, just at this time the air in the lungs also reached the limit, so he pointed to the water surface and swam up first.

The location of the hole is not far from the water surface, I kicked the water a few times and felt a warm float above my head, just gasped for two mouthfuls and a splash exploded around me, I choked on the water and immediately coughed violently, and after relieving myself, I saw Hao Jian floating next to him like a dead dog, snoring and panting, looking at his panting appearance, I was really afraid that he would not be able to suffocate here!

Liu Yunsheng was the last to come up, his lung capacity was much better than ours, and after coming up, he only took a breath to recover, and swam over to step on the water and asked seriously: "Do you think my analysis is reasonable?" ”

"What analysis?" I was stunned for a moment before I remembered Liu Yunsheng's string of sign language just now, although I didn't want to admit it, I could only reply embarrassedly: "I can't hide it, in fact, I don't have much research on sign language, so let's come up and talk about what we have to say." ”

"It's okay," Liu Yunsheng nodded, glanced at me and Hao Jian, and said in a deep voice, "Don't you think that hole is a little abnormal?" ”
