You Told Me to Be Debauched, So What's With This Eternal Sage Emperor?

[Western fantasy + tyrant king + multiple heroines + elves + succubi + centaurs + monster girls + dragon knights + no saintly do-gooding + ruthless and decisive]

After transmigrating to a world of swords and magic, Ryan became an illegitimate prince.

From the start, the old king died horribly while practicing abyssal magic, and the throne fell right into his lap.

The kingdom was surrounded by demons on the outside and controlled by powerful ministers within.

Everyone thought he would be easy to manipulate…

[Ding! The Host has put on the crown. Tyrant System activated!]

As long as he ruins the kingdom’s fortunes, he gets rewards. If the kingdom falls, he can ascend to immortality on the spot!

Ryan was overjoyed. “Diligently managing the kingdom isn’t my thing, but I’m an expert at debauchery and vice!”

So, on the first day of his reign, the new king kicked his young brother aside and announced in public that he would take the late king’s favorite consort by force!

The elven saintess, the abyssal succubus, the vampire progenitor… The brave are the first to enjoy the world!

The ministers wept bitterly. “Your Majesty, if you keep acting this way, how is our Silvermoon Kingdom… turning into a divine kingdom?”

The demons sharpened their blades. “The tyrant is a monster, turning everything upside down! Brothers, follow me… What the hell! Are there spies all around me?”

The elven chief approached in a fury. “The king of the Silvermoon Kingdom is an idiot. We should… Huh? Why have you all surrendered outright?!”

Years later, Ryan gazed at his invincible empire, which had not only survived but conquered the Abyss and the Divine Realm, and fell into deep thought. “I really only wanted to be a tyrant. How did I end up unifying the continent?”
