If that's the case,
the true strength of The Master of Liu Village is probably even stronger by three parts than They have conceived.
After all, to achieve this step, to cover the karmic cause of a group of Immortal Kings, even They would need to expend a great deal of effort, and it's not something that could be accomplished overnight.
Because even at Their level of Realm, They cannot defy the great Karma, still living under the dominion of grand causality.
Otherwise, the backlash of force would be enough to annihilate Their God Souls.
Trivial causes can naturally be ignored, but the magnitude within Karma is not the literal size it implies.
Take an example.
Sometimes, slaughtering a city of Ten Thousand Clans might be a minor cause.
But sometimes, killing a single individual could possibly taint one with a great cause.
Therefore.
They mostly choose to remain silent in The Boundary Sea, rarely taking action personally.
