The underground tunnels were shrouded in blood mist, with chilly gusts blowing through.
Every inch of ground as far as the eye could see was packed with writhing evil spirits.
They crowded against the walls, the ground, the ceiling, howling desperately to crawl out.
But the purple light of the Soul Refining Formation filled the tunnel, forming a barrier that prevented the underground spirits from penetrating the tunnel.
Li Muyang and his two companions ran through the tunnel, their feet only centimeters above the sinister faces of these spirits.
This visual experience of running through a "pipeline" full of evil spirits was intense to the extreme.
Soon, the three came upon other disciples from the Demon Sect.
Although most of the disciples within the core area of the formation nearly perished, the many Outer Sect Disciples scattered in other regions had not been attacked by demons.
