After the Villain Shizun Was Born, He Cried at the Wrong Grave

After being reborn, I became the strongest villain in the world of cultivation. In his previous life, he sacrificed his life for the sake of the people of the world, but ended up being betrayed and separated from his relatives, and his soul was scattered. In this life, I choose to go dark and vow to make all those who owe me pay with their blood. It happened that the young apprentice who was killed by me personally became my disciple again. I sharpened the knife with a sneer, but I heard him kneeling in front of the old grave late at night, choking: "Master, don't be afraid, this time it will be me who saves you." Wait... Why is my name engraved on the tombstone?
