You can't get too far in any of the three CONDOR HEROES TRILOGY novels without encountering wulin warriors fighting in some sort of formation. In L/ROCH, you've got the Cheun Jen Sect's 7 Stars Big Dipper Formation, the Beggar's Union Dog Beating Formation, the Ancient Tomb Sect's Double Sword Formation, and Peach Blossom Island's eponymous formation. Skip over to HSDS and you've got Mo Dong Sect's Jen Mo 7 Section Formation and Shaolin's Demon-Subduing Circle Formation.
In DGSD, however, nobody uses formations. In DGSD, individual fighters seem to blast and shoot internal energy left and right, and the concept of battle formations seems nonexistent.
