Yichen commented as he took them all: "Mn. That's already enough."
He then used his spirit qi to send those poisons towards the barrier.
The poisons were then made to immediately circulate all over the air that was inside the barrier.
As the air got contaminated, the hell abyss dragon slowly started to react to it. His violent movements were quickly slowed down and shortly, its entire spirit qi was subdued.
It slowly came down from the barrier and was soon fallen into a dull state.
It appeared that its spirit qi was rapidly diminished, therefore, it became too tired.
The beast then slowly curled up and rested on the ground with its eyes wide open.
Unlike the other beasts or the humans who were experimented with the spirit qi subduing poisoned, this Beast Emperor dragon was a different case.
It was very powerful that the poison wasn't able to subdue it totally and made him unconscious.
