The flow of time is different between the Abyss and the real world, which means Bai Yan can spare some time to deal with situations arising in the Abyss while Fu Chao and others study the power and influence of the Snow Wolf Clan.
Bai Yan's strength was recognized by all the Demon Lords who were imprisoned. When such a powerful figure appeared before them, they chose to surrender without hesitation.
In the Abyss, a world where the strong are revered, choosing to surrender when you cannot defeat an enemy is not a shameful act.
Betrayal, deceit... behaviors like these are what most demons despise.

Bai Yan's appearance made these Demon Lords instantly realize that Bai Yan's power was something they could not resist.
