The mining tunnel was very dim, and the Luminous Pearl could only illuminate a small area; the traces of the mine's passage were quite new, clearly indicating that it had been recently opened.
After just over a hundred yards, Chu Zheng felt a surge of rich Earth Qi rising up, along with faint traces of poison and a whiff of deathly Yin Qi nurtured from corpse bones.
This was Turbid Qi, which for ordinary martial masters, would gradually erode the body like a Death Sentence. Even if they took a Poison Warding Pill, they couldn't stay in the mining tunnel for long.
Such Turbid Qi had no effect on Chu Zheng. He didn't even take a Poison Warding Pill and switched directly to internal breathing, drawing on the Yuan Qi between heaven and earth for sustenance.
After entering the mining tunnel, the group of just over three hundred people quickly split into several small teams, each choosing a direction to explore.
