Lin Chen, the hidden 'SSSSS-Class Prison Dragon' guarding the secrets of an ancient cultivation prison, lives as a loser food delivery guy in the city to lie low. Until one day, Su Wan, a wealthy heiress fleeing an arranged marriage, bursts into his rental house and begs him to 'pretend to be her boyfriend'—their embrace awakens the 'Prison Guard System' that's slept in him for ten years! Since then, he encounters vengeful cultivators while delivering food, forced by the system to solve problems with his Dragon power 'low-key'; in cohabitation with Su Wan, he hides his identity and acts cowardly while secretly helping her with family troubles. When enemies track him down via Su Wan, and system missions point to 'restarting the cultivation world', Lin Chen realizes: his 'laying low' was never a choice—it's fate's most explosive counterattack script!
