I Am the Demon Emperor Reborn

For five hundred years, I, Li Han, have been a genius. For the sake of all the people in the world, I have sealed the Tianyuan and the Demonic Abyss... But all the people in the world, relatives, and lovers have betrayed me, Li Han. But I, Li Han, will live another life, and I must make those who betray me pay the price. Li Han vowed to take revenge. And the things in Tianyuan Demonic Abyss were sealed by me. Is he really a devil? Why is the place sealed by me a sinner and a bloody person like me? And are the sects in the world really moral? Is Buddhism the real Buddha? What is the real image? What is morality, what is Buddha, and what is demon? Is Buddha really a Buddha, and is demon really a demon?
