After the battle with the Weirdo Maker, the person most impacted should have been Zhu Shi, yet she noticed her own oversights more quickly than either Mazao or myself. Perhaps it was her professional consciousness as the Luoshan Impermanence still at work; in comparison, Mazao and I were truly outsiders.
After realizing this, she didn't call us over but specifically summoned Lu Youxun, most likely wanting to handle the aftermath herself. As for Lu Youxun being called to work overtime late at night, she probably didn't give a thought to whether he would be worn out or not.
Of course, the investigation and cleanup of the scene were originally Luoshan Patrol's duties. It would have been more surprising if Lu Youxun didn't deal with such a significant event. Moreover, there were fragments of the Weirdo Maker's self-destructed minions scattered around the site, which also needed to be collected.
