After transmigrating to a wuxia world where five kingdoms stand, Li Chang'an wants nothing more than to lie flat in his courtyard home in Changshan City. Fortunately, he awakens the "Stay-at-Home Sign-In System." As long as he stays home in peace, he can obtain Heaven-grade techniques, the peak cultivation of a third-rate expert, a grandmaster's brewing skills, and rare treasures. So he lounges in the sun, sipping tea and brewing wine, while welcoming Huang Rong, whose culinary skills are beyond compare, and the cold, domineering Yaoyue into his little courtyard. While others risk their lives roaming the martial world and fighting to level up, he lies flat and gradually rises to the pinnacle of a wuxia life.
