According to Zhou Tian and that Human Emperor's strength, only a fool wouldn't realize that without the appearance of a third force, the situation of that Human Emperor who disappeared at the same time as Zhou Tian would definitely not be favorable.
Once the Human Emperor died by Zhou Tian's hand, those powers understood very clearly the impact that the Human Emperor's death would cause. And those powers at that time certainly did not want to see that situation happen.
