Once an individual becomes too powerful, the authority of the royal family will be challenged.
In this world with all kinds of extraordinary powers, being an emperor is a very difficult thing. Not only do you have to deal with the destruction caused by those extraordinary people, but you also have to always worry about those guys breaking into the palace and taking the emperor's head if they are unhappy.
Any reputation that could revive the royal family in this situation?
A man with a system decides to fight violence with violence.
Become the strongest and beat all those extraordinary guys who violate the rules until they kneel down and call daddy!
In the name of a tyrant, a disobedient guy has no value in existence.
