The man with a cold heart turned out to be a good emperor;
The handsome man with thin skin and tender flesh turned out to be a good general.
The emperor who has no heirs has a childish prince brother who is careless;
The general with a mysterious life experience has a twin brother who is the champion with a vicious tongue.
Four people can create a dynasty;
Four people can overthrow a dynasty;
Four people, after loving each other vigorously——
Miracle! The country remains the same.
