There's A Evil Living In My Body

He used to be the Young Lord of the Moon God family. Recommended by his brother, he participated in the "War of Chaos" in the Light World and became the world's number one Asura.
However, while returning home, he was ambushed and injured. Surviving, somehow he returned home, but he found his clan's downfall, his father and fellow clan members slaughtered, and the Moon God Clan exterminated. To his shock, he discovered his brother was behind the treacherous act.
As if his brother's brutality wasn't enough, he found that his lover helped his brother seize the throne and played a major role in this disaster.
Roaring in madness, he rushed to them, wanting to tear this couple apart. However, how could he be his brother's match in that condition? He died with endless hatred and anger!
They threw his body into a desolate cemetery and left the scene with laughter. No one expected that a wisp of black gas entered his body, which helped him revive as the God of Slaughter, bringing eternal doom upon his enemies!
