The Lord of All Realms, Chu Yuan, tired of high-position life, concealed his cultivation and adopted an alias, coming to the dilapidated and weak Cangwu Sect to be an ordinary disciple, only wanting to experience the sect daily life of mortals. But the Cangwu Sect's crises are endless, the ancient seal on the back mountain is in imminent danger, powerful enemies from the Xuantian Sect and Blood Sword Sect eye covetously, and the sect members repeatedly fall into life-and-death perilous situations. While fishing and slacking off, Chu Yuan secretly protects sect mates like Sect Leader Qi, Wei Tieshan, and Gu Xiaowan, accompanying them through trials to grow. Through the Tianduan Mountain Range trials and fighting against external enemies, he repeatedly makes a move at critical moments, yet always conceals his true strength, silently guarding this mortal little home belonging to him.
