When Bai Zemin activated Gravity Manipulation in reverse, what he expected was that a scene similar to when the First Order blue-scaled snake he killed a couple of hours ago spat out its poisonous mist was to occur.
However, things don't always turn out the way you expect them to.
Swoosh!
The speed at which the blue flare of fire was traveling certainly slowed down and several flames shot up into the sky lighting up the dark night. The problem was that contrary to Bai Zemin's expectations, the torrent of fire continued to move in his direction.
Taken by surprise, Bai Zemin unconsciously raised both arms in front of his face hurriedly to cover himself.
Bang!
A bang that, while inferior to the bang caused when Bai Zemin fell from the sky was still undoubtedly loud, shook the forest again on the same night and within a short space of time of the previous one.
