Lu Xiaochuan, the chief disciple of the Taixu Sect, possesses the Chaos Great Dao Sacred Physique. However, because the "Chaos Black Hole" inside his body devours spiritual energy, he has been stuck at the Qi Refining Realm for ten years. He can only earn money to feed the black hole by charging for knowledge, collecting challenge fees, and taking on all kinds of odd jobs, all while keeping a low profile to protect himself. In the eyes of outsiders, he is lazy and greedy for money, and the newly initiated princess Cang Ling'er even mistakes him for a swindler. But through one crisis after another, she discovers that this seemingly improper "Senior Brother" is actually unfathomably powerful: he can pinpoint cultivation bottlenecks, defeat formidable enemies, and protect the sect. Faced with mounting pressure from outside forces, Lu Xiaochuan is forced to step in time and again. While continuing to crack jokes and collect spirit stones, he secretly leads the Taixu Sect toward dominance in the Northern Wilderness.
