Congratulations to the host for binding the (Check-in System). As long as you act like a salted fish in the sect for a day, you can obtain top-tier cultivation techniques! Lin Gou unexpectedly transmigrated to become a sweeping Taoist boy of the number one Xuanhuan sect. While others stay up late fighting monsters and overcoming tribulations, he stays up late researching "Cultivation World Food Delivery" and "Secret Recipe Spicy Malatang." The system tells him to pretend to be useless, but he accidentally feeds the sect's divine beast into a fat tabby cat. Until one day, a demon lord descends from the heavens.
