I Help the King of Heaven to Regain His Strength

After traveling through time, the good thing was that I became a prince, but the bad thing was that I became Ran Min's subjugated prince. In order to survive, I helped King Wu Miao to unify the world, end the chaos of the Jin, Southern and Northern Dynasties in advance, and end the darkest history of the Han people, the Five Husbands' Rebellion in China! "What? You want me, an emperor, to listen to your prince? You are really rebelling against Tiangang!" "You are the Heavenly King Wu Dao who has descended to earth. Only by unifying the world can you return to heaven and become an immortal again, so you have to listen to me." After unifying the world, Ran Min's eyes were full of excitement, "Prince, I will definitely be promoted when I go to heaven this time, right?" "Definitely!" "Great!"
