The Heavenly Demon King, the Blood Demon King, and the other three Demon Kings of the Demon Race, all did not hesitate.
"I submit!"
"I submit, quickly, quickly withdraw your power!"
Yang Yan would naturally not withdraw his own Emperor Body Power!
Because once he withdrew his power, without its suppression, the five Demon Kings would inevitably become fearful and attempt to escape.
If they escaped, Yang Yan would have a hard time catching up to them and subduing them again!
There was simply no way he could achieve that!
Especially if they fled into Hell!
Yang Yan would only be able to travel there through a soul's traversing of space passageways!
His physique wouldn't make it through, and without his Emperor Body Power, trying to suppress the five Demon Kings with his current soul strength was simply a dream!
