Based on this reasoning, one can imagine that if Zhou Tian's followers do not possess certain strength, then even if they are sent into the weakest worlds, at times when they cannot protect themselves, even if Zhou Tian had arranged everything well, they might not have the opportunity to make an impact.
It was precisely because of this reason that Zhou Tian paid such attention to those Angels. One reason was that those Angels possessed substantial strength, and another was that they had remarkable talent. Even the God of Light was worried that one day these Angels might surpass him as the ruler.
Given the various advantages of the Angel Race, Zhou Tian ultimately decided to have them become the initial inhabitants of the Abyss World. And when necessary, he was unreservedly ready to rely on their strength to achieve his goals.
