Whatever was happening could be actions of pure instinct that these strange trees had, but given their Soul Realm, Tianlong Yun guessed that probably the trees thought that this was their golden chance.
The way they were running in a line towards the hole, with the big guys taking the front it appeared like more than just a simple attack, as it looked more like an attack formation.
They seemed to be truly organized in their attack as in no time they were in front of the hole. Appearing there they immediately struck with their vines and tried to block the hole.
It seemed to be a well-thought plan from them, as they first tried to block the hole, and then enter the inside of the formation and finally confront their enemies.
The disciples inside the formation were a bit surprised by all this in front of them, as it was something truly unexpected.
