Defeat Ma Dai and Pang De, then enter the Tong Gate itself. Weapon Box is located just past the Tong Gate, to the south of the map in between the tents.
Other notes:
A very straightforward requirement, but can be tough if you're not used to dealing with Xu Zhu. His slow movement and attack speeds are off-putting to players, but he has a unique Musou attack which can make up for it.
Xu Zhu's Musou can normally get a single hit on standing enemies, but multiple hits if it were somehow to catch a midair opponent, chaining hits by juggling them with the rotation speed of the attack. Pinning an enemy against a wall or other barrier is the best way to do this, it is harder but also possible to use knockup moves like C2 and C5 to combo into a Musou this way too.
Again, ensure you are the one that gets the kills on the two required officers, and enter the Tong Gate from the direction you started from, the weapon won't trigger if you go around the back where Xu Huang approaches.
