Qin Zhen ventures deep into the demon realm, using her extraordinary ability to connect with plants and trees to search far and wide for spiritual plants. When the ancient tree of the Monkey Clan, which has stood for ten thousand years, fails to bear fruit for years, she steps in and brings its withered seeds back to life. Heading west, she encounters swirling cold mists and strange disturbances beneath the waves. She joins forces with the Stone King to explore mines and search for medicinal treasures. Meanwhile, her younger sister, Qin Jia, ventures into the frigid deep-sea currents, nourishing her life-bound sword with Frost Marrow of Condensed Tides. The sisters each continue to cultivate and grow stronger, all in the hope of finding spiritual herbs to bring blessings and longevity to their elders. Plants have feelings, and the road to immortality is long, but together they press onward.
