If Owen Bertram was still merely at the Fourth Great Realm, he would have used conventional methods, temporarily lurking beside Alen Charle and secretly investigating the entire event. But now, with two individuals at the Sixth Great Realm here, it would naturally be a force to break all laws and methods, no need for beating around the bush.
The arrival of the King of Souls, placing a false demon ghost like Alen Charle in ambush in the Abyss, was not merely "putting out one's full strength to hunt a rabbit", it was practically akin to blasting mosquitoes with a nuclear bomb. If Alen Charle understood the situation, he should be honored instead.
Well, Alen Charle himself probably wouldn't feel honored...not important.
