Tian Hua transmigrates into the body of a prince, the least remarkable one of them all.
A year later, the emperor unexpectedly issues an edict appointing Tian Hua regent. With no court officials backing him, Tian Hua is panicking like crazy when, all of a sudden: Congratulations! The year is up, and the System has successfully bound itself to you!
Tian Hua straightens up at once. “Make way! It's time for me to show off!”
... ...
Emperor: “I'm eighty percent sure I'll break through this time. In a year, I'll be the strongest person in the Southern Continent. I'll lead the Huaxia Dynasty out of the Southern Continent and conquer the whole mainland. That's why I deliberately made Tian Hua, who has no connections among the court officials, regent. When I return, everything will still be mine~ Hahaha.”
Look at my reading time, who is longer than me~
