The Arrival of the Supreme God

[Pure Power Fantasy] The ultimate BOSS comes down to live among mortals, leaving all the twists and hardships to the supporting cast, while the villains meet their end... Power fantasies are hard to write, and stories where the protagonist is absolutely invincible are even harder. So this book gives the supporting characters plenty of time in the spotlight. The big shot handles the grandstanding and wraps things up, while the story is written as normally as possible whenever the protagonist doesn't step in. It also strives to build a believable world, so that changing locations won't make all the earlier stories and characters vanish without a trace.
