Zhang Fangtong continued: "Slowly, I moved a little bit, ten meters, five meters, three meters, two meters...... Finally, I stood close to the big hole, and then stopped. ”

"It's very strange that the courtyard of my hometown is lit all year round, especially in the partial courtyard, because there is no room, so I don't have to think about the brightness of sleeping, and the lights are bright all night, like daytime, no different from the day. It is precisely because of this that I can lie on the rockery and see the movements of my cousins. ”

However, the bright daylight in the courtyard suddenly and inexplicably lost its effect after shining into this large hole. It can be clearly seen that there is a light shining into the hole, but when the light shines in, it does not bring any light, and the bottom of the big hole is still dark, and nothing can be seen. It's as if the light has been swallowed up by a big hole. ”

"Because the light has no effect, it is impossible to see the bottom of the cave at all, you can only see the position of the hole three or four meters deep, and then it is completely dark inside, you can't see it at all, there is no way to infer how deep the big hole is, let alone see what is under the hole."

After thinking about it for a while, I walked to the aisle paved with cobblestones more than ten meters away, pulled out two pebbles at random, and then walked back to the big hole. After aiming a little, I let go of my hand and let the pebbles in my hand roll downwards in a freefall motion! ”

"After the stone fell from my hand, I pricked up my ears and listened carefully, trying to see how long it would take for the stone to hit the ground, and to guess how deep the hole really was."

However, something strange happened again, three seconds...... Five-second ...... Ten seconds...... Twenty seconds ......, I waited for a long time, but there was no sound at all, not even the slightest sound, and in the end I waited for half a minute, and there was still no sound of stones falling to the ground. ”

"Impossible? How can there be no sound? Could it be that this is actually a bottomless pit? Faced with this situation, I was a little overwhelmed, and after thinking about it for a while, I speculated that I might have missed it, and the sound had already come out, but I didn't hear it. ”

Thinking of this, I picked up another stone, and then let go of my hand on the top of the big hole as well, and let the stone fall freely. Only this time I was more focused than before, and even before I let go, I was holding my breath and listening carefully, lest I miss something again. ”

"However, five seconds...... Ten seconds...... Twenty seconds...... Pinching the time, half a minute passed in a hurry, and I was even more confused because of it. There was no sound, the same as the last time, and there was still no sound of stones falling to the ground, as if the big hole really had no bottom, which made me completely panic. ”

"How is that possible? I must have not heard it again! I didn't believe in evil, so I went to pick up stones again, this time not just one or two, but a lot of them, and I also picked a few big ones. Back to the edge of the big hole, this time I threw this large handful of stones into the big hole at the same time, I don't believe there is no sound this time! ”

"Sure enough, just as I thought, this large handful of stones was thrown down, and this time there was finally movement at the bottom of the cave. And the sound is not small, crackling several times, all of them are very crisp stones on the ground. I roughly calculated that it would take about four seconds for the stone to land, which is about 20 floors when converted into height. ”

"It is worth noting that when I threw that large handful of stones, several of them fell crooked as soon as they came out of their hands and smashed against the wall a little down from the hole. However, after smashing it, it was not all the sound of stones colliding with the wall, but also a very crisp sound similar to the sound of an iron pipe being struck. ”

"After figuring out the depth of the big hole, I cautiously took another step forward, and after my body was completely parallel to the position of the hole, I slowly bent down, I squatted down, stretched out my hand and began to grope around the side of the big hole where it had just been smashed, trying to see if it was the same as my guess."

"There wasn't anything else on the edge of the hole, so I easily touched the iron pipe that had just been smashed, and pressed it down hard and it was very strong, without a hint of shaking. I continued to grope down the pipe, and soon found another pipe under it, which was also very strong in the same horizontal position. ”

"So I can be sure that, as I thought, the iron pipe is actually a ladder that extends downward, and if nothing else, the iron pipe should have stretched all the way to the bottom of the cave before disappearing."

"It's normal to think about it, such a big hole that is obviously full of many man-made traces, no matter what its role is, there is a ladder for people to climb on the side, it is really a very natural thing, unless the person who built the big hole never thought of going down, or never wanted to come up again after going down."

"It is said that newborn calves are not afraid of tigers, and at that time I was young and much more courageous than I am now. After finding the ladder at the bottom of the cave, I didn't even hesitate, I climbed to the ladder, stepped on it twice, felt that the quality was really good, and after it was solid, I began to climb down. ”

Having said this, Zhang Fangtong shook his head with a wry smile: "What is young." Do things recklessly, but for now, I definitely don't dare to climb down, even if I really want to climb, it must be best to prepare all safety measures, and I won't be so reckless! ”

"But at that time I didn't know what it meant to be reckless, but there was always a youthful momentum, and I climbed down the ladder step by step, because it was pitch black inside the hole, so I couldn't see anything clearly, so I could only rely on intuition and feeling to stretch out my feet to test where to go next. Now that I think about it, I'm really scared, if there was a little accident at that time, whether it was slipping under the soles of my feet, or feeling that my feet were empty when I felt wrong, I was afraid that I would definitely fall to death! ”

"But at the time, I didn't have as many ideas as I do now, I was just curious, curious about what was under the big hole. Could it be a treasure hidden at home? But if it is really a treasure, then why did the cousin drive the beasts in the family down and fall to their deaths? I wondered if I had ever connected this big hole with the rumors about our family that had been circulating in the village for many years......"
