Can you recommend a novel based on the fact that I only remember a little bit of the plot but can't remember the name?

I don't remember the name of the novel, but I remember some of the content. The main character's father sent him to an island to study, but there was a Heaven List, Earth List, and Human List on the island. I remember that he was the first on the Earth List and then challenged the Heaven List. Those who knew would add points. [Additional question: Is it a fantasy? It seems that his father sent him to the island to study, or did he go there himself? Anyway, there is a Heaven List, Earth List, and Man List. The protagonist seems to be a low-key person who pretends to be a pig to eat a tiger.] I just remembered this novel. I remember reading it before, but I forgot about it today. [Additional question: The first on the Earth List can challenge the last on the Heaven List. There are 100 people on each list.] The first on the Man roll challenged the 100th on the Earth roll, then the first on the Earth roll challenged the 10th on the Heaven roll. There were only 10 on the Heaven roll, and there seemed to be 100 on the Man roll. It seemed to be a very large academy that even some large families were afraid of. All the people who came out of it were experts...
