Heavenly Doctor and Imperial Mentor

Li Yu transmigrated to ancient times, where he once helped the Three Sovereigns and Five Emperors create humanity’s glorious age.

When humanity declined and was enslaved by the gods, he helped Emperor Qin Ying Zheng launch nine campaigns against the Heavenly Court.

In the final battle, however, Li Yu was betrayed by a traitor among humanity and died, body and soul destroyed.

When Li Yu awoke, he had returned to the modern age, back inside his original body.
