There is a weird grocery store in Wutong Lane, Haiyun City.
The boss, Gu Ci, is a lazy young man. The store only sells old and tattered items. He never bargains about the price and buys as much as he likes.
No one knows that this seemingly harmless man was once a taboo being who terrified the underground world.
No one knew that the "fruit knife" he was playing with could cut into pieces the body-protecting aura of a half-step master; that the broken jar gathering dust in his shop sealed an ancient demon.
Until that day, the cold female CEO Lin Qingxue opened the dusty wooden door in order to save her grandfather...
"Now that you're here, follow my rules."
"In this shop, if it's a dragon, you have to coil up, and if it's a tiger, you have to lie down."
This is the story of an invincible boss who lives in seclusion in the city and just wants to peel apples in peace, but is forced to train various dissatisfied strong men.
