Here is the translation:

  The old man had just walked out of the cave for a few steps when he suddenly heard a faint rustling sound in his ear. The sound was like someone's light footsteps, and people often become extremely sensitive to sounds when they are in trouble. He slowly stopped walking, but as soon as he did, the rustling sound disappeared. After not taking many more steps, the old man came across a stone coffin. As he approached it, he saw that there were some strange patterns carved on it, and in the corner, there were several jars placed there. The old man immediately became excited and rushed to the jars. They were covered with dust, but after wiping them clean, he opened the lids and found that they were filled with "Yuan Datou" (a type of Chinese coin). At that time, people had already started collecting Yuan Datou, although the price was not high, it was still a small fortune.

  The old man continued to open the other jars, and they all contained the same thing. Until he opened the last jar, where he found a small box with the same patterns as the stone coffin. There was a small lock on it, but at that time, he didn't have any concept of protecting cultural relics, so he simply used a rock to lightly tap the lock open. Luckily, the box wasn't big, and he was able to put it in his pocket.

  At that time, the old man didn't understand the significance of this thing, but he always felt a psychological effect from carrying it with him as if it were a treasure. After my grandfather retired, he let the old man take over his job at the power plant. Every year, there was plenty of rainwater in this place, and over time, an artificial lake had formed. The water was clear, and the local villagers had put some fish fry in the lake. A few years later, they had grown big, but the villagers always had some reservations about this artificial lake. Although the water was clear to the bottom, no one dared to swim in it, no matter how hot the weather was.

  The workers who knew the inside story said that every year, someone would disappear from this lake. At that time, there was a young man named Sun Erhu, who had a very good relationship with my grandfather. One evening, just as my grandfather was about to go swimming in the lake with some colleagues, Sun Erhu suddenly grabbed him and pulled him aside. Although he was small in stature, he was incredibly strong and managed to pull my grandfather away from the group.

  My grandfather looked at the people who had already entered the water and felt a bit annoyed. Sun Erhu said, "Uncle Cao, you mustn't go swimming in that lake. It's not clean." My grandfather paused for a moment, cleared his throat twice, and then asked, "How do you know?" Just as he was about to say something else, there was a sudden cry from behind them.

  My grandfather and Sun Erhu turned around at the same time to look towards the lake. They saw that several young people were struggling to swim towards the shore, and the cries for help came from their mouths. My grandfather quickly rushed towards the lake, but he was once again grabbed by Sun Erhu.

  "Uncle Cao, don't go!" Sun Erhu said firmly. At this time, my grandfather didn't have time to think much, so he simply dove into the water. It was strange that although it was midsummer, the water felt icy cold as soon as he entered it, like it was winter. The colder he got, the more his legs became numb, and his sense of rhythm while swimming began to break down.

  My grandfather kept telling himself to stay awake. Suddenly, everything around him became quiet, and my grandfather's heart skipped a beat. He quickly turned around, but there was no one beside him. The numbness and cold sensation also disappeared at the same time. He floated alone on the surface of the water, and the moonlight was particularly bright. The lake water was pitch black, and suddenly, a thick layer of fog rose up from it.

  A lantern broke through the fog, followed by a white boat. My grandfather knew that something was wrong and wondered if it was...the legendary ghost ship? My grandfather's back felt cold, and he wanted to swim away, but his body couldn't move at all. At this time, my grandfather suddenly discovered that there seemed to be a faint light coming from beneath him.

  The light grew bigger and bigger, and the white ghost ship disappeared as it approached my grandfather. My grandfather heard another cry for help behind him, and he felt a surge of water rush into his nostrils. His nose hurt, and he instinctively swam upwards. As soon as he broke through the surface, he was shocked to find that he had unknowingly swum to the center of the lake.
