You don't understand. No one's saying 'lightly smack them and scold them'.
KILL THE FUCKING GUARDS. Incinerate their remains, leave no evidence!

Agreed. He should have gotten his balls together and gone in after her. Xianxia might be xerox'd garbage in most cases, but their MCs don't pussy around like Isekai protagonists. They pull out their sword, summon the wind and rain, throw mountains, and charge into heavily-guarded fortresses when this shit goes down. I find that slightly more engaging than Isekai MCs being so submissive and hand-wringing and leaving enemy humans alive.
