A down-on-his-luck modern-day delivery driver transmigrates into the body of a good-for-nothing emperor and obtains a forbidden cultivation technique that the Heavenly Dao would not allow to exist. From then on, he defies heaven itself. The world laughs at him as a good-for-nothing, but he quietly rises to become the strongest emperor and rule all under heaven.
