[Urban High Martial Arts] + [Villain Protagonist] + [Mythology Subverted] + [Decisive and Ruthless] + [Feel-Good Read]
Su Mu, a transmigrator, awakens the Heaven-Defying Fate Book.
To grow stronger, he must enter mythological worlds, play the legendary great villains, surpass them, and accumulate “Fate-Reversal Points.”
Starting mission: Become the new keeper of Five Elements Mountain and let Sun Wukong experience what it means to get a thorough beating.
When the Monkey King yells, “I refuse to accept this!” Su Mu pulls out Moral Education and Advanced Mathematics, smiling kindly. “You don't accept it? That's fine. Finish this set of problems, and I'll let you out.”
