Tiangong Kaizi

When the world first opened, the three tribes of gods, demons and demons were born with magical powers, which coincided with the origin of the word. Only the human race has nothing and can only work as coolies for the three races. The source word is hidden in wind, fire, water and electricity. The human race understood characters from the fish, birds, gods and demons, and every time a character was created, the heaven and earth shook. I have memorized it for three thousand years and saved hundreds of words. I no longer work as a coolie, but I am still the weakest. Each of the four tribes has a guardian who is of equal strength and keeps each other in check. But the guardian of humanity is dying. When he dies, the other three tribes will pounce on him. This is the world Shirakawa was born into.
