Gao Tianlei, a modern-day maintenance worker, accidentally travels to a fantasy cultivation world. He has neither a spiritual root nor the ability to read cultivation manuals, yet he develops a bizarre form of turbid qi powerful enough to shatter formations. Farting, burping, and even a rumbling stomach can become astonishing attacks. As a result, he is repeatedly mistaken for an evil cultivator. Amid pursuits and misunderstandings, he joins a cultivation sect and befriends companions such as Yuanhua and Liu Ruyan. Together, they journey from the sect to the upper realm, becoming entangled in the Heavenly Gate's judgment and a crisis threatening the nine realms. With his quick wit, perseverance, and unique 'belly thunder,' Gao Tianlei repeatedly overcomes seemingly impossible challenges. Along the way, he learns to shoulder responsibility, protect his companions, and fight for justice for those oppressed by prejudice.
