Zhao Dezhu, a simple farmhand from a mountain village, has only two lifelong ambitions: to look after his two acres of poor farmland and marry a lovely wife! But who could have guessed that his old black bull, Niu Hai, would go mad after a heartbreak? Not only does the bull sport a green fringe and flirt with females everywhere, he even causes a scene at the gates of the Xuanyuan Sect, smashing the sect's grand entrance arch with his head! The prestigious sword cultivators are furious and draw their swords, ready to slaughter the bull and throw him into a cooking pot. This crosses the line for the honest farmer. Whoever dares touch my bull, I'll dig up their ancestors' graves! Grabbing his iron cattle-driving rod, Zhao Dezhu boldly stands up to protect his beloved bull. Unexpectedly, the violent spiritual energy from the grand formation awakens the ancient divine power sealed within his body. The supposedly righteous and exalted sects tear off their hypocritical masks and lay down a deadly killing formation. But little do they know that the old black bull is the real powerhouse!
