In fact, those NPC demigods had considered this problem as well, and because they had thought of it, they had left some members within the NPC large army at that time. The role of those NPC demigods was to increase the combat power of their subordinate NPC army, ultimately achieving the capability to take down Zhou Tian's beastmen.
However, even though those NPC demigods already had a high opinion of Zhou Tian's beastmen, should a conflict actually break out between them, Zhou Tian's beastmen would still likely bring about some surprises for those NPC demigods at that time.
After all, Zhou Tian had been preparing for so long that, no matter how strong those NPC demigods were, dealing with them wouldn't be that simple.
As a result, when that group of NPC demigods showed up, Zhou Tian did not avoid the battle at that moment.
Upon seeing Zhou Tian engaging in battle, the NPC demigods first breathed a sigh of relief, then immediately surrounded Zhou Tian with their numbers.
