The imperial army, led by Xiao Che, has made a major move against Qinglong Stronghold. They mobilized a huge number of laborers and auxiliary troops, cutting down forests at the foot of the mountain to clear a broad road by force, and dispatched several teams to search the rear mountain. This tactic targets Qinglong Stronghold's two greatest advantages—its difficult terrain and hidden tunnels—and is the work of an experienced veteran commander rather than Shen Yi or Xie Yan.
