In order to reduce the pressure on the mortgage, programmer Zhang Wei rented out the bedroom in the school district to Bai Qianqian, who was too beautiful to be true. He didn't know that this new roommate was actually a fox fairy who had been practicing for thousands of years, and he came here to benefit from the aura of his "humanoid spiritual stone". Immortal magic frequently fails to work on Zhang Wei, the steely straight man. The hair growth soup is regarded as sesame paste, and the proposal of dual cultivation is regarded as wanting to peek at the code, causing countless jokes. In a shared life full of collisions of species differences, the two went from misunderstanding to understanding, and jointly faced the provocation of the wolf demon and the test of the fox tribe, and straight male thinking turned out to be the key to breaking the illusion. In the end, they broke through the identity barrier and confessed their feelings, and clues to Zhang Wei's own mysterious blood also emerged, adding new variables to their future.
