Joy of Life: The melon-eating prince sees through Fan Xian's fake death

[TV drama fan fiction, some references to the original work]
The screenwriter traveled through the world of Joy of Life and became the Crown Prince Li Chengqian. He obtained the melon-eating system, and became stronger by watching plays and eating melons.
Originally, he just wanted to be a leisurely new king who ascended the throne safely.
Having seen too many injustices of superiors bullying the inferiors and treating human lives as worthless, he decided to cooperate with Fan Xian to change this cannibalistic world.
"You earn your salary from the people, and it's easy to bully the people, but it's hard to bully God!"
