Heaven Ascension Immortal Sovereign had always exercised a somewhat detached control over Han Muye.
Bridging time and space with the method, the Celestial Array Dao spurred a convergence between the two parties, ultimately leading to a clash of their powers.
The Heavenly Cycle Formation was, after all, one of the methods to reshape heaven and earth.

The more thorough the integration, the more aligned the source powers became.

Han Muye was the master of Nine Mystic Mountain.
