Attacking Zhou Tian would be in the best interest of the Pig Demons, in comparison to attacking the checkpoint, no matter how one looks at it.
If Zhou Tian could be killed, there would be no need to break through the checkpoint. The Beastman Tribe would naturally be thrown into chaos. Winning this way would certainly count as a victory. Meanwhile, if they were to fight Zhou Tian, the Beastman Archers would not dare to shoot arrows at them again. Taking these aspects into account, the Pig Demons, without paying any mind to Zhou Tian's intention, quickly turned their attention to him at the first opportunity and initiated an encirclement and suppression.
However, Zhou Tian was incredibly composed in the face of the encircling Pig Demons.
