Although at the Immortal King level, battles are no longer purely about power.
But the power of the Immortal Country itself is also a form of strength.
Acquiring the Heart of the Power Rules still enhances one's power.
Especially for someone like Brother Cheng, whose Immortal Country's foundation is exceptionally strong, the overall enhancement will be significant.
However, although this rule is strong, it is very difficult to comprehend.
Moreover, most Quasi-Emperors, even if they cultivate the Power Rule, will not choose to merge with it.
The reason is simple: the Dominator of the Power Rule is the Lord of the Barbaric Realm.
He is an ancient powerhouse, not inferior to the Great Azure and Cyan Dragons, existing since the early Immortal Realm.
Completely unshakable.
Choosing this Main Rule Heart basically means it's impossible to become an Immortal Emperor.
But how could Brother Cheng care about such a 'minor detail'?
As long as the rule is powerful, it's good!
