My name is Chen Du. I used to be a criminal police officer, but later I became a madman looking for his wife and daughter.
They were "recycled" - not dead, but completely erased from reality. No one remembers their existence, except me.
In order to retrieve them, I took the initiative to enter the "furnace" - a screening field built by high-dimensional creatures. There is a judging game every seven days, the loser is recycled, and the winner is qualified to continue to exist.
