While Ye Lin was in seclusion, the armies of the Xuanhuang Great World began advancing toward the Heavenly Demon Great World under Qin Wudao's command.
In the cultivation world, the strong were revered. Qin Wudao's talent and combat strength had earned the respect of the other Immortal Realm experts, so command naturally fell into his hands.
But if Ye Lin had been here, then the command would most likely have fallen to him.

What was more, Supreme Saint experts would occasionally appear to cause trouble. It often took three or even four Immortal Realm experts just to hold back a single Supreme Saint expert.
But to kill one, ten Immortal Realm experts had to strike together to ensure victory beyond all doubt.
