Part 4/10:
After some convincing, Straw finally meets Dol-Yi, the authentic Drill-Bit. In a scene filled with tension, Man-Sik and Sang-Goo arrive, inadvertently clearing Dol-Yi and Straw from suspicion due to the absence of injuries, thus allowing the plot to progress. The stakes escalate as Geon-Woo, a wealthy oil refinery magnate, hires Dol-Yi to accomplish a perilous task: drilling specific holes against a tight deadline, wickedly tied to an impending factory demolition.
