I'm a Boss in the Underworld

I thought about the title of the work all night and didn't want to repeat it. After all, it is original. I have been single for 20 years and my hand speed is still acceptable. Let's not say much: let's get to the point. The story happened on that day in mid-August. Ye Tian, ​​the protagonist of the story, was taking a bath in the river. He accidentally picked up a box. The box was quite heavy, about twenty kilograms. At first, I thought it was an express train. When I took it ashore, I saw a lock, which was already rusty. I hurriedly ran home, and then a sudden trip began mysteriously. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
