Su Nianyi, a descendant of a once-renowned demon hunter, graduates only to find herself unemployed. She takes over the dilapidated demon-suppressing inn left behind by her grandfather and unexpectedly becomes bound to a cross-world business system, unlocking five demon employees from a demon-suppressing tower in the cultivation world. Each powerful demon employee has a special ability, but the inn's initial business is disastrous, earning a string of negative reviews. To save the hotel from imminent bankruptcy, Su Nianyi comes up with an unconventional online shop, selling the demons' special services for just 0.9 yuan. She initially thinks it's just an online gimmick, but to her surprise, the demons' clones really travel thousands of miles to provide their services in person. After countless customers experience the supernatural firsthand, they flock to the Immortal Island Hotel in the middle of the lake. With visitor numbers skyrocketing, Su Nianyi gradually embarks on a fantastical business venture spanning two worlds.
