I died, was reborn as the most hated enemy prince, and was forced to take on the hellish mission of saving my motherland.

Personal Attendant: [Eating and waiting to die for a lifetime], progress 37%
Emperor Dad: [Unify the continent and establish an eternal empire], 40% progress

[Time limit: six months]
[Penalty for failure: death of millions of civilians, eternal sin]
