The heaven and earth are divided into three realms - the upper realm is inhabited by the gods, the middle realm is the vast continent "Phaseless Realm" where humans, demons and demons live together, and the lower realm is the "Secret Ruins" where souls return. According to the legend, only by breaking the shackles of fate of the "Shadowless One" can one transcend reincarnation and achieve one's true self. However, for thousands of years, no one has been able to see the true appearance of the "Shadowless Lord". There is only a prophecy left: "The form has nothing to rely on, the form has nothing to rely on, the heart is empty and clear, and all dharmas are unified."
