The Soul Travels Through the Underworld: Starting from the Wandering Soul to Become an Immortal

I traveled to the underworld with my living soul and turned into a fist-sized soul fire. Although it was very weak, I was the only one who could cross the barrier between the two realms and return to the yang realm. Swallow wandering souls, fight Yin soldiers, and kill Yin generals. Flee to the Yang Realm, build a physical body, and become an immortal. I am cultivating the path slowly, my Taoist heart is very strong, just to live forever in the world of heaven and earth.
