As Yan Zhaoge had begun leaving the Extreme Northern Snowy Plains, re-entering the North Sea, far away in the lands of the Fire Domain, calmness had gradually disappeared from the area.
The southern part of the Fire Domain contained hundreds of thousands of great mountains that formed a ceaseless chain, its climate greatly hot.
And amongst the mountains, heading underground, it was an even more blazing hot world.
There, below the ground, existed a world formed completely of flames and lava.
The Southern Underground Palace was one of the Eight Extremities World's great danger grounds alongside the Extreme Northern Lands and the Great Western Desert, its dangers also much more direct as well as brutal, truly being an underground world of a sea of flames.
Even for the Sacred Sun Clan, whilst being a sacred ground, it was also a forbidden land.
