In the underground river cave where one couldn't see their fingers, Luo Zheng and the others shivered from the cold. If not for the special thermal suits, they couldn't withstand the chill inside the cave, especially the cold wind, eerie like it had emerged from hell. Although the wind was gentle, only a brushing sensation, it was equally bone-chilling and overwhelming. Fortunately, there were enough flashlights for illumination, which brought a sense of security and put everyone at ease.
The group advanced rapidly, using running to fend off the cold. No one knew how far they had traveled when the chilling air gradually gained a hint of warmth. The river narrowed, and the flow weakened. An intersection in the tunnel appeared ahead, causing Luo Zheng's expression to turn grave. He signaled the team to stop and instructed Mountain Eagle to go ahead and scout the path.
