Strength is the basis of everything, especially in this Yin and Yang world, where the rules are made by the strong. The weak obey, the strong ignore. Strength is everything. Humans, ghosts, gods, and demons are divided into four realms: humans, gods, ghosts, and demons. The fight continues, but all this may be just the mercy of a better interface. The truth of all this is... No matter what, if anyone touches you, I will kill him!
