King Level bosses within the Monster Force already stand at a considerable height. Even if the Bone Demon Clan wasn't ravaged by players, it's estimated that their strength would barely reach that level. Under such circumstances, a barrier that couldn't withstand the King Level bosses proved to be enough to trap those Bone Demons.
But now, in a completely unnecessary situation, the NPCs somehow managed to create a barrier that could trap a King Level boss. Obviously, the NPCs must have made significant investments in those barriers, and considering what the NPCs have put into it, Zhou Tian figured that breaking through their arrangement would be quite difficult.
Of course, even if the barrier was extremely difficult to break, Zhou Tian was never going to give up at this moment. Therefore, his assault on the barrier was unchangeable, and what he truly needed to pay attention to was how he would go about ensuring he could break through that barrier.
