There is a legend in this world. In the legend, there is a fireball that flew from the depths of the universe and fell to the ground. No vegetation grew where it fell, and the yellow soil was burnt black. The huge fireball turned into a big demon, causing trouble in the world. Wherever it passed, humans turned into a pile of bones. Not even an ant could survive. Xin De's eight masters in the world desperately resisted and were able to seal the big demon underground for billions of years.
