Demon: Peace in the Dark

No harem.

Hei Xin is a man who has lost everything he owned, watching them be tortured and murdered in front of him. After achieving the revenge he longed for. He committed suicide next to the body of his murderer.

When he opened his eyes, he found himself sitting on a throne in a great palace. He had not died, but rather his soul had transmigrated into the body of the most hated and strongest cultivator on the continent.

That's not all, the demon was the final villain of a novel he had read. His disciples, partner and friends had betrayed him.

The experience of his past life has made him make the decision to get away from everyone, to explore the continent, looking for a way to resurrect his dead family.
