The distance between the second and third levels of the Secret Realm seemed considerable. At the seven cultivators' pace, they walked for a full quarter of an hour, covering roughly ten li, without seeing the end.
Another quarter of an hour passed before a fiery red light appeared in their sight amid waves of scorching air.
The fire spiritual energy here is already as dense as that of a top-grade third-tier spirit vein.
A Qi Refining Cultivator practicing a Fire Element cultivation art here could easily double their cultivation speed.

Wisps of flame burned across its relatively calm, slowly flowing surface.
As far as the eye could see, boiling magma filled the bottom of the entire space, sending up waves of heat
