Thirty thousand years ago, during the time of chaos, Siyin, the God of War, sacrificed his soul to the sky and built eight fragments to patch up the sky to ensure the stability of the human world, the demon world, and the divine world. Ten thousand years ago, the war between gods and demons disturbed the three realms, and the fragments fell accidentally, but they didn't know where they were. Gods and demons have no choice but to hand over to heaven from generation to generation in order to achieve peace in the three realms.
Purpose: Survival from desperate situations, mutual salvation
