After killing that resentful spirit, Ye Wudao continued onward.
His search method had changed.
His physical body moved slowly across the gray earth, while his intent body floated five hundred zhang away, sweeping over the surrounding points of light like an invisible searchlight.
At the same time, he deliberately released a trace of his intent body's aura, faint and subtle, like lighting a small lamp in the darkness.
That little lamp was bait.
The resentful spirits in the Reincarnation Realm were extremely sensitive to the aura of the living.

He could search for soul lights while killing resentful spirits to nourish his intent body.
After absorbing the first resentful spirit, Ye Wudao discovered a pattern.
A resentful spirit's resentment was tied to the depth of its obsessions in life.
