Once the group left its range, the Poltergeist stopped attacking them. It then continued to dismantle all the man-made objects in the place, condensing a hand structure that it extended and grabbed hold of the second mural that was thrown off far away.
The moment the hand structure exited the village, the Ghost Qi within it seeped out in excess, getting annihilated automatically. It was the restriction faced by a Poltergeist. It was unable to exit its range.
But now, despite suffering damage and losing a tremendous quantity of Ghost Qi, the Poltergeist extended the hand structure and soon grabbed hold of the second mural, retracting the hand immediately.
The moment the mural entered its range, the Poltergeist seeped part of its body into the mural, refining it into its shell. Immediately, a tremendous reserve of Fear Qi exited the mural, getting absorbed by the Poltergeist that began to grow at a staggering pace.
