The Holy Infant possesses the complete power of the rules, which is the real body of the Divine Spirit. No wonder the Linglong Heavenly Sovereign could control the power of the rules after merging with the Holy Infant.
"Senior, may I ask, why would the Holy Lord let you merge with such a precious thing as the Holy Infant?"
That was Long Yan's confusion.
With the Holy Lord's methods, it would not be difficult to cultivate the Linglong Heavenly Sovereign up to the Divine Spirit Realm; it is completely unnecessary to let Linglong Heavenly Sovereign merge with the Holy Infant.
Certainly, it's not just to let Linglong Heavenly Sovereign ascend from Initial Entry Emperor Territory to the Emperor Realm Peak in one fell swoop.
