Gods, act on behalf of heaven.
And how to act on behalf of heaven is to use the authority in hand to execute the will of heaven and earth.
It can be said that authority is the foundation of gods; for gods, losing the authority in hand, even if the Divine Position remains, means losing the path for further progress in the future, even shaking their own foundation.
For a god, authority is an untouchable existence. Any creature coveting their authority is their mortal enemy, an irreconcilable foe, and must be eliminated.
Thus, Ju Mang is clear that in wanting to seize the authority held by the Wood Virtue Star Lord, he is shaking the foundation of the other's Divine Position. This is definitely not an easy time, and the other party is impossible to compromise on this matter.
Therefore, he is prepared to take it forcefully, even if it means offending some people and fighting a battle with that Qingling Primordial Lord.
