Heavenly Thief Demon Venerable was a Demon from Beyond the Heavens. He excelled in space path, created theft path, and possessed immense talent in refinement path as well.
His life had been devoted to transcending the Gu Master World and returning to his homeland.

The essence of a Gu Immortal refining Immortal Gu was to use their own will to drive out and eliminate the wild will within the Immortal Gu itself, ultimately turning the Immortal Gu into their own tool.
