He killed tigers and dragons and was respected by all people. Until the tree fell, his mother was expelled and died, his father was killed in court, his eldest brother's life and death were unknown, his best friend gave false testimony, his sweetheart married another man, his martial arts skills were useless, and he was exiled to the Jedi. The hero is dead.
What crawls back from hell is a monster that eats resentment and has no feelings. He smiled and entered the house of his enemy, squeezed his brothers into empty shells, ruined the reputation of the hypocrite, and refined the entire rotten rule into his own strength. He defeated all his enemies and sat on the highest throne.
Then he discovered that he could no longer taste the taste of wine, smell the fragrance of flowers, feel happiness, and could not shed a drop of "human" tears.
He killed the hero and became the devil. In the end, he discovered that the cold throne was the eternal cage he had built for himself.
