Part 6/10:
The challenges faced by Dol-Yi's team come to a head as they confront geological hazards, causing heated disputes over their drilling strategy. The escalating tension boils over when an accident leads to Jeob-Sae’s volatile temper and an altercation soon ensues. For Dol-Yi, this mission represents more than financial gain; it is a test of leadership and respect toward his team.
Despite the chaos, the team perseveres, finding themselves caught in a perilous situation under the adverse effects of an explosion caused by their tunnel work. As two of their own get trapped, a moral crossroad arises: should they escape or dig deeper for survival? Through sheer determination, they break through to their trapped comrades just as Man-Sik and Sang-Goo's investigation reaches its peak.
