90. "Spy" Yuge

"The internal security of the Korabo Legion is quite lax. There aren't even any breathing masks or filter cartridges provided in the guard room..."

Suppressing his breath, Noland Lee quickly rummaged through the guardroom under the illumination of the coal lamp, skillfully searching without daring to slack off.

He opened drawers, turned over bed boards, and checked storage cabinets, searching every possible location but never finding any trace of breathing masks or filter cartridges.
