The tunnels were not interconnected, many areas were collapsed and blocked, necessitating detours.
No wonder Nie Xiaoqian took the initiative to guide Fang Zhou; he might have gotten lost if he were on his own.
According to Nie Xiaoqian, these tunnels were secretly constructed by the monks of the former Lanruo Temple, but the reason for their construction was unknown.
They reached the end of the tunnel, where Nie Xiaoqian opened a door and floated out to scout the surroundings before beckoning Fang Zhou to come out.
The outside was still shrouded in thick fog, preventing Fang Zhou from discerning their location, but with Nie Xiaoqian as a guide, they avoided wandering aimlessly.
In the fog, occasional ghostly figures or demons appeared, but with Nie Xiaoqian's help and cover, Fang Zhou remained undetected.
