Su Tang picked up an injured little beast, and the next day it called her owner in human words. The little beast turned out to be the ancient mythical beast Bai Ze, with incomplete memory but carrying the secrets of heaven. Bai Ze's recognition of the master aroused the covetousness of all parties. The demon Xie Yun, Tianji Pavilion Xiao Jichen, and senior sister Jiang Xuetong were successively involved, and Meng Po from the underworld was also secretly watching. Su Tang transformed from a wasted outer sect disciple to a descendant of the ancient spiritual body. She shared the same bloodline with Bai Ze and gradually uncovered the truth about the great catastrophe of the world - she did not pick up the mythical beast by accident, but was the "Tribulation Eye" chosen by fate.
