During this confrontation where Taoist Monarch Tianji took action against Great Emperor Ziwei, seasoned Dao Lords had already anticipated the intervention of the Jade Emperor, and under such circumstances, Emperor Wenchang, regardless, would not stand idly by.
When the Sword Emperor stepped in to block the Jade Emperor, Taoist Monarch Xuantian naturally appeared outside the Chaos Void, blocking Emperor Wenchang's path.
Unlike the decisive actions of Taoist Monarch Tianji and the Sword Emperor, Taoist Monarch Xuantian did not strike immediately when he intercepted Emperor Wenchang.
One reason being that Taoist Monarch Xuantian didn't see the necessity for a confrontation, as although several seasoned Dao Lords took action today, it was merely to teach a lesson to both Great Emperor Ziwei and Emperor Jade, not to harm their lives fundamentally.
