The cave leading into the false vault was deeply dark. Only after traveling dozens of miles within the mountainous paths, winding around trees, did one delve underground and enter. As Yan Moshan entered, he began to fall rapidly, activating his mana to gently descend. Charging downward, he had no idea how far he had advanced, but after at least tens of thousands of miles, Yan Moshan finally reached the deep underground, where a sea of fire appeared before him, with magma boiling and scalding like oil, flowing freely.
The temperature here reached thousands of degrees; consider then how hot the depths of this magma must be, likely above ten thousand degrees. Even for the formidable Yan Moshan, with his indestructible **, entering such high temperatures would not be easy.
