No One Supports My Sky-High Ambition, So I’ll Climb to the Summit on a Mountain of Bones

Demonic cultivator + no System + devious survivor + ruthless and decisive. This is a dark story, so don't read it if that's not your thing.

For survival, for immortality, a mountain of corpses and a sea of blood are no price too high.

To attain immortality, he sacrificed all living beings.

To obtain a superior constitution, he dug it out of his clan brother.

For resources, he robbed tombs.

For cultivation, he trained on bones and people.

Immortality? Easy. I'll simply become a Venerable.
