South of the South District, the dark forest is one of the several dangerous forbidden lands within the Kunwu Realm. In this forest, there is no trace of sunlight all day long, the sky is black, and the forest is filled with ancient trees that are black in color. These ancient trees originate from another plane and are known as Black Crystal Trees.
Black Crystal Trees emit a kind of black crystal aura which creates a powerful pressure, and this black crystal aura can also temper the body.
In the dark forest, there lives a race called the Black Crystal Clan. The people of the Black Crystal Clan have incredibly strong bodies, immense strength, and do not cultivate martial arts or spells. They only cultivate their physical bodies, and with the strength of their flesh alone, an adult can withstand a blow from a Martial Saint.
