Qian Wangsun exclaimed, "Through a 100-kilometer-long tunnel without any light?"
Song Zhen replied, "It's not just that. I grew up in Nan Mountain City. The Hell Corridor, besides being pitch dark with no visibility, also had numerous runes carved into it. Every section of the tunnel had drastic changes in spiritual energy."
Song Zhen continued, "When people stay in the dark tunnel for a long time, with no sounds or sight, only hearing their own footsteps, breathing, and heartbeat... hallucinations gradually begin to appear. Moreover, due to the changes in spiritual energy caused by the runes, the hallucinations induced by the Hell Corridor are even more terrifying, containing a trace of the Dao Zang's essence."
Qian Wangsun exclaimed, "The Evil Sect actually engraved the contents of Dao Zang into it? Have they gone mad?"
