I Made a Contract with the World-Destroying Witch, I Modified My Memory and Became Emperor

I traveled through time and became the most useless prince in the empire, Cloxiu. When I was about to die, I signed a contract with the World-Destroying Witch and gained absolute power and memory modification. This king's power makes my enemies become playthings at my fingertips. I want to take back everything I have lost! "The order you received is to swear allegiance to me." The guards who were chasing me became my loyal vanguard in the next moment. "Your lifelong wish is to help me regain the empire." The arrogant noble who hates the royal family declares his eternal surrender to me. "In your memory, I am your only master." The entrenched evil dragon has been engraved in its recognition that I am its only master. From the border town to the royal capital, the roads I walked were all paved with modified loyalty. The cities I refer to all open their doors to the true emperor in false memories. This is a crusade for the throne woven with lies. When all enemies become the staunchest allies, what he usurps is not only the empire, but also the "past" of the entire world. As Cloxiu approached the emperor's throne step by step, the secret of the witch who gave him the power to play with people's hearts also emerged from the cracks of darkness.
