Lu Yizhou was quite amused seeing how enraged Ji Yan was. In one glance, it was apparent that he was in the guests camp. The way he wanted to eliminate the werewolves was too obvious. Wasn't he afraid that he would pull aggro[1] this way and end up being the target tonight?
Perhaps it was just how he was or perhaps he had a way to escape from the werewolves' ire. One thing for sure, he was unable to sit still when something like this happened and in exchange, he unknowingly hogged all the limelight. Really typical of a protagonist.
Lu Yizhou had spent two days with Ji Yan in the previous quest and could say that he knew the man's basic personality. Ji Yan was not the kind of stupid man who would act rashly, especially if the price he had to pay was his own life. The fact that he was clearly pulling all attention to himself meant that he had thought of the way to escape if worse came to worst.
I remember LYZ don't even know what NPC means when the game started and now he knows what aggro is! Is 666 a good teacher?? Lolol
