Above the three realms, there exists a Ghost Realm of Return to Void, which is the source of spiritual energy of heaven and earth, maintaining the order of all realms. Ten thousand years ago, the guardian of the Dao realm held the spiritual pulse of dust bone, suppressing the turbid qi at the bottom of the ruin with his own spiritual bone, ensuring the stability of the cultivation world in the world. A hundred years ago, the righteous path's number one sect, Xuanchen Sect, suddenly suffered internal turmoil, the former sect master mysteriously fell, and half of the dust bone fragment guarding the sect was missing. Since then, the sect has declined, talents withered, and it has been reduced to a third-rate sect in the Qingxuan domain.
