The sky of the divine realm has truly cracked. Thirty-seven small worlds are collapsing simultaneously, yet no gods in the divine realm dare to step in. Emperor Di Yao and Empress Yun Hua hold hands tightly, take the initiative to request orders, and plunge into the most perilous ancient dynasty—starting right seven days before the crown prince is assassinated. Disguised as a divine doctor couple traveling the world, on the surface they heal the sick and save lives, but behind the scenes they manipulate the tides, saving the heir with a single needle, exposing a fake blood letter with a single word, and purifying a usurping powerful official turned monster with a single palm.
