In the second generation of Tianyu, Huang Pizi punished the Feng family for the destruction of his family because of wrong answers. The third generation did the opposite after being reborn. He knelt down and recognized him as the reincarnated father of the Monkey King, and bound him through the rules of heaven. Huang Pizi had no choice but to become the backer of his family, solving troubles such as landlords and Taoist priests. When the Black Mountain Old Demon attacks, Tian Yu calls out to Tathagata as the son of the victorious Buddha. The Tathagata appears and assumes the identity of Huang Pizi, punishing the Black Mountain Old Demon to protect the Dharma for a hundred years. From then on, Huang Pizi protected his family sincerely, and Tianyu's family finally found peace.
