In the year 2031, the earth has further advanced in its technological developments. Though there are democracies, republics, and several other systems of governance followed by various countries, there is still one country that adheres to the feudal system—the Arinphiam Empire.The empire is divided into three parts, where the royal family coexists with the central government to control the empire, keeping it as one of the strongest nations on planet Earth.The richest man on this planet belongs to this empire, where noble families still exist, governed by laws specifically made for them by the royal family instead of the central government.Marquess Avendial Croceaus has finally returned to the past, to the year 2031—a year before the tower's arrival—on the date where his downfall began.As he returns to the past, he discovers himself facing the initial setback of his life, where accusations of treason are soon to fall upon him.This world-building novel presents a completely fresh story with new ideas and plots, where the efforts of the main character lead him to become the one who changes his fate as a villain.Content warning: Adult R-18 Chapters without any warning, as they could be part of the story, a slow but well-paced story to provide the detailed idea about the world-building, a weak main character with the debuff of seven curses, making him even cut off from the chances of growth.

Ning Yechen used to be the Demon Lord. He singlehandedly took over the Demon Realm and attacked the Heavenly Realm. His name preceded him throughout the Six Realms. He got tired of fighting, so he quietly went into seclusion and became a happy hermit.One night, an Empress from the Heavenly Realm fell into the Mortal Realm after someone drugged her with an aphrodisiac. She inadvertently fell into his room, and they made out. After the deed, the Empress quietly left. Just when he thought he would never see her again, she showed up in front of him ten years later, bringing a child, saying it was his daughter and demanding accountability from him! “She’s your daughter. You have to be responsible for us!” Ning Yechen was stunned!
