This time, Lu Chuan did not choose to stay on Earth, nor did he shatter time to go to the Immortal Realm; instead, he traveled alone to the outer realm, tracing the roots, and found the source of the Evil Spirit, a broken coffin that was already decayed beyond recognition.
Lu Chuan drifted alone in the outer realm for a thousand years, finally discovering a way to kill the Evil Spirits, which was to seal them in the coffin.
So Lu Chuan split into three entities; one traveled through shattered time to the Immortal Realm, using the name Yan Yang, to guide the Evil Spirits within the Immortal Realm to the outer realm, sealing them in the coffin.
