It can be imagined that when the prohibition set by Zhou Tian is triggered, those Heavenly Gods must feel as if they are witnessing themselves being constantly drained of blood. In that situation, their fear of Zhou Tian's ability is completely natural. Even Zhou Tian himself, if faced with such a situation, definitely wouldn't perform much better than those Heavenly Gods.
Reflecting on his own situation, Zhou Tian thought about the terrifying nature of the prohibition's ability, and naturally, he didn't believe that those Heavenly Gods wouldn't feel afraid. Knowing that such a prohibition was placed within them, even if faced with ten times the temptation, without assurance they could escape Zhou Tian's prohibition ability, those Heavenly Gods would likely rather die than betray Zhou Tian.
