Strength was the foundation; though Zhou Tian had successfully dodged their attacks, having observed Zhou Tian's performance, the NPC demigods still revealed a hint of excitement at that moment.
Given the situation at the time, although Zhou Tian momentarily outlasted them, the NPC demigods were also aware that, even if Zhou Tian could withstand their attacks, his energy consumption would definitely exceed theirs. Thus, even if Zhou Tian didn't show signs of defeat in the short term, if they kept up their actions, Zhou Tian wouldn't be able to last much longer.
Once the NPC demigods considered this, they already had substantial confidence in their impending victory. After all, the circumstances at that time were clearly to their advantage, and as long as they maintained that superiority, they would eventually defeat Zhou Tian.
However, just when the NPC demigods thought they had taken the initiative and would not need much time to win, something accidental happened at that moment.
