The brat who was gleefully conversing with Monologue under the Moon was none other than the student Ah Fa. A kid like him did not have the prudence of an adult, so his blatant show of his mirth further infuriated Monologue under the Moon.
In the end, Monologue under the Moon still had to care for The Black Hand's image. They were a mercenary group and not a guild. With the guild's aim to dominate others, it could get away with bullying the weak and helpless. As for a mercenary group's aim to do business online, it could never prey upon the weak. While a mercenary group could showcase its PvP prowess, it had to maintain a forthright and pristine image; only by doing that could they be well-received by the public and their business continue to grow.
Thousand Miles Drunk seemed to have expected this, so he was very bold at letting this bunch of unruly, low-level children act as bait.
