So I Am the Demon God Emperor

Liu Chuan transmigrates to a world undergoing spiritual qi revival with a shop System, but he cannot cultivate, so all he can do is open a Treasure Pavilion.

What he doesn't know is that every random item in his shop is an invincible imperial-grade treasure. Even a cup of tea or a painting can help people advance several cultivation realms.

Before long, countless people flock to his shop, and the empire's fortunes begin to change.
