So, when those NPC demigods began to flee at the first instance, Zhou Tian also chased after them at that moment. Based on the situation at the time, Zhou Tian immediately caught up with the opponent. And, with his own strength, Zhou Tian killed an NPC demigod after a few casual attacks.
Seeing Zhou Tian's performance, those NPC demigods fled even more desperately. Even to increase their chances of survival slightly, the already few NPC demigods chose to split up at that time.
Though splitting up would completely lose their ability to confront Zhou Tian and basically meant certain death for anyone Zhou Tian caught up with, splitting up naturally increased the difficulty for Zhou Tian to chase down those NPC demigods. Not to say that it would be harder for Zhou Tian to catch up with the NPC demigods, but killing all of them became seemingly more difficult.
