Monologue under the Moon headed to Yunduan City's north gate to meet with the other members of The Black Hand mercenary group as he sent over a member with fast movement speed to the Hall of Mercenaries to accept the small guild's request.
There were many perks, besides having a larger player capacity, to a mercenary group being at a high level. For instance, a level 1 mercenary group could only pick up one mission at a time from the system, while a level 5 mercenary group could do five missions simultaneously. Naturally, the system had no way of limiting the amount of missions mercenaries could take from others in private. Furthermore, a high level mercenary group could assign certain members to have the right to accept missions, just like how that player Monologue under the Moon had sent to the Hall of Mercenaries could accept missions on behalf of The Black Hand.
The title is a reference to the 21st stratagem in the 36 stratagem, which is essentially a diversionary tactic where someone would mask themselves or even directly remove certain elements in an effort to appear as something else entirely.
