Mo Hua neither has the realm nor the capability to restrain a late-stage Golden Core Cultivator.
He only has Foundation Establishment.
He is not truly an "Evil God", unable to control believers through the altar's blood sacrifice like the Master of the Great Wilderness.
Therefore, Mo Hua can only wear a look of "indifference" — even if he wasn't indifferent, there wouldn't be another choice.
Mo Hua maintained a calm demeanor: "You may betray me, for my betrayal is insignificant, but..."
Mo Hua looked at Lugu, his gaze deep, "the betrayal of the Divine Lord is unforgivable."
"Never, ever betray the Divine Lord..."
Lugu's eyes sharpened, not knowing what to think, he slowly nodded.
...
The transaction between the two parties was concluded.
Mo Hua saved Elder She from Lugu's hands, then had Chi Feng cripple his legs and feet, temporarily imprisoning him.
There should still be other secrets within Elder She.
