Jiang Yuanzhen, despite his contempt for Great Zhou, also knew that even if Imperial Heaven Realm could completely suppress Great Zhou, the Empire would not act against Great Zhou now. The reason was simple: even if Great Zhou was wiped out, the current Imperial Heaven Realm was not capable of controlling the entire world.
In the past, the Jiang Family was a descendant of the Emperor of Mankind and belonged to the Royal Family, but the problem is that a dynasty cannot be sustained by the Royal Family alone. For instance, the current Great Zhou, even if all the powerhouses of the Ji Family were dead, the collaboration with the military and the Six Gates and other forces could still support the entire Great Zhou.
Now, the Jiang Family was no longer a dynasty but a sect-shaped clan force, and it was impossible for them to completely control the world on their own.
