I, the Agent of the Abyss

My name is Gu An, an ordinary trainee psychic. Until I personally absorbed the essence and blood of the last demon king in the world. I have become the only emperor in the world and the public enemy of the whole world. The Demon Division wants to slice me up for study, and the Demon King wants to capture me and use me as a resurrection vessel. Until I saw the ancient truth from the essence and blood—— The so-called invasion is nothing more than a failed "return". And I am the only "key" to this lost world. When forces from all sides force me to make a choice, I held the drop of boiling royal blood in my body and smiled. "Stop fighting." "Now, I am the disaster itself."
