Ling Yuan, a little cat demon adopted by the Ninth Princess of the Celestial Clan, was betrothed to the Celestial Crown Prince. Targeted by jealous rivals, she suffered one persecution after another and hid in the Netherworld. She had hoped to live quietly and help Meng Po grow medicinal herbs, but was framed once again for causing chaos in the human realm. The Celestial Emperor punished her by sending her to undergo trials in the mortal world. The Crown Prince followed her, while the God of War fell for her and secretly came to her aid. As she ascended, she was deceived by the Spirit Clan and accidentally wounded her adoptive mother. Ling Yuan's demonic powers awakened, and her true identity was exposed. Rejected by the Celestial Clan, she returned to the Demon Clan and took on the responsibility of finding spirit stones and rebuilding the Demon Realm. To stop the wraiths in the Iceflame Cavern from wreaking havoc across the six realms, she became a stone spirit and purified them, finally restoring peace to all six realms. Moved by her sacrifice, the Spirit Clan summoned the collective will of their people to revive Ling Yuan's primordial spirit. Through hardship after hardship, Ling Yuan came to recognize the unwavering love of Crown Prince Luya, who had always helped her in silence. Though she endured countless trials, she ultimately found sincere love.
