My Disciples and Grandsons Were Scummed, and I Broke Out of Their Graves!

After traveling across the continent for 30,000 years, I managed to reach the ceiling of combat power but ended up in the grave. I wanted to ignore the world, but who would have expected that my clever disciple would be ruined? Ancestor, I am so angry that I am so angry that I am so angry that I burst out of my grave! Back to his old profession of killing!
