The protagonist, having degenerated into a “loser” after being unable to find employment, gets caught up in someone else’s attempt to commit suicide-by-train and ends up traveling to another world. The numerous cheat powers he demands from God are all granted to him. But contrary to expectations, these powers bring about disastrous consequences for the protagonist.

Having reincarnated into another world, the optimistic protagonist (Yuuri) starts his(her) heart-warming training days with his(her) teacher.

“If he’s being badass, I’m gonna plant my own crops. If he messes with me, he will not live past next year.”

Traveling through time, he became Zhang Gui, a foreign relative of the Tianqi Dynasty. Because he didn’t want to be tortured to death by Li Zicheng in the future, he had to embark on the road of harming the powerful and bureaucratic officials of the Ming Dynasty.

The Yanguan scolded him for coercing the king and making disorderly manners.

The prince scolded him for being greedy.

The official hates him for being mean and cruel.
