At the deepest level of the underground prison, in front of the cell imprisoning the undying Abyssal Spawn.
Compared to the other cells, the gravity crystal layer of this cell was half a meter thick. This showed just how wary they were of the Abyssal Spawn, as well as the fact that this cell was a separate structure rather than being built alongside the others.
When this cell was originally redesigned, the plan was for the criminals in the other nine cells to be able to see the undying Abyssal Spawn inside. If they noticed any unusual movement from it and informed the guards, they would have a chance to be transferred to the second underground level.
There was no chance of leaving the third underground level. Unlike the prisoners on the second and first levels, they could not even go outside for an hour of fresh air each week.
This arrangement existed because if the undying Abyssal Spawn ever escaped, no one could imagine how it would retaliate against the Alliance after being imprisoned by them for so many years.
Su Xiao looked at the Abyssal Spawn in the cell. The creature, which had constantly radiated malice while inside, had now stopped moving in an abnormal manner. It had sensed that the person capable of killing it was standing outside the cell, causing its aura to grow increasingly violent.
The underground prison had already been quiet, but an inexplicable pressure now filled the air. The Lion King, Furious Shark, and Banshee in the nearby cells all turned their gazes over. Hatred, who had been hanging upside down in his cell, and the Mind Master, who had been sitting motionless on his bed, also walked to the gravity crystal layer and looked toward the confronting Abyssal Spawn and Su Xiao.
