"Wait a bit longer, the collapse of the Hidden Sect Plane is the best opportunity to strike."
Ultimately, everyone reached their final conclusion.
The strength of the Hidden Sect made Heaven and the Penglai Realm very apprehensive. In the past, while the Penglai Realm and the Heaven Plane existed, it was still difficult for the Hidden Sect to attack Heaven or Penglai Realm and annihilate them.
But now, with the Heaven Plane already collapsed and the Penglai Realm not able to hold on for much longer, it is only a matter of time before it collapses. At that time, the three forces will all live in Earth Space, and a war among the Three Realms will inevitably happen. Without the plane barriers as the last line of defense, the strong from Heaven and the Penglai Realm have no confidence in defeating the Hidden Sect.
So, for the sake of safety, they must wait for the best timing to take action.
