Since that thieving Heaven showed no regard for sentiments, performing such a thankless task as slaughtering the donkey after it finished milling, the Earth Immortals, being the ones being slaughtered, naturally wouldn't be polite either.
They simply defied their mother of Mountain, carving out their own domain and proclaiming themselves kings over their own land.
With their own territory in tow, they directly withdrew from the control of the Heavenly Path and became their own carefree kings of the Mountain.
By detaching themselves from the order of the Heavenly Path, the rules of Heaven could naturally no longer descend upon those sovereign Heavenly Immortals.
And the Great Tao painstakingly cultivated by the Heavenly Immortals themselves would naturally belong entirely to them, allowing them to use it without reservation within their own carved-out domain.
