Apart from Rules, Everything Is Cause and Effect

Other people's golden fingers are given by the system. My golden finger was given by a dead man. After my grandfather passed away, I dug out a pocket watch among his belongings. Four words are engraved on the back of the watch: See the cause and know the effect. That night, the pocket watch dragged me into a world of trials created by the Seven Pillar Gods. There is no law, no morality, only one iron law: rules are supreme, and those who violate them will die. Others survive within the rules, betray and trample on each other. I'm different. I can "see" the thread behind the rules - each rule is linked to the person who wrote the rules. Rules are written by people and can be changed by people. Until I found out the origin of the pocket watch: twenty years ago, a teacher entered here with it and died in the third round. Before he died, he left the watch outside. And it was my grandfather who accepted this watch. My grandfather taught all his life and never mentioned a word about it until his death. The world is ready to pay me back one by one the things he has hidden from me for twenty years. I was the pawn assigned to the game. But the person who arranged for me forgot to ask? Do you want to let this seed fall?
