An immortal maiden was born into the mortal world, with a spirit-vein key hidden in her soul. From childhood, Li Nianxian resonated with the spirit veins of heaven and earth, unaware that she bore a heaven-ordained duty to protect them. When a disturbance in the spirit veins led her to Qin Yuxuan, a mortal emperor secretly searching for their source, the bond they formed awakened their shared destiny: he was an ancient Yinglong dragon, banished to undergo tribulation and bound to the Fate-Severing Halberd; she was a guardian immortal carrying the spirit key, her immortal essence entwined with the rise and fall of the Three Realms.
The Chaos Realm Lord breaks free of his seal, seeking to devour the Three Realms. The Fate-Severing Halberd shatters into six pieces scattered across the immortal, mortal, and nether realms, throwing karma into chaos: memories are altered, spirit veins corrupted, and reincarnation thrown into disarray. Li Nianxian uses the essence of her immortal birth to activate the spirit key, while Qin Yuxuan awakens the divine power of Yinglong. Together with the Li brothers and those bound to them by bonds of love, they cross icy plains, brave the Crimson Flame Mountain, explore the netherworld, and enter the Divine Ruins in search of the halberd’s fragments. They protect their mortal parents and cherish the warmth of everyday life, finding the power to dispel evil in a bowl of braised pork and a single red thread.
Love can reconcile life and death; mortal affection can break through chaos. They use the immortal grace of Li Nianxian’s birth to stabilize the spirit veins, Yinglong’s divine might to cut through illusion, the brothers’ unity to fend off powerful foes, and their bond as husband and wife to withstand the backlash. Facing chaotic illusions and the manipulation of karma, they hold fast to their original purpose: peace in the Three Realms does not come from the battles of aloof immortals alone, but from a two-way bond of protection, where an immortal maiden braves tribulations and Yinglong wields his halberd, and mortal affection thrives alongside immortal destiny.
Atop Pangu’s altar, the power of Li Nianxian’s immortal birth merges with Qin Yuxuan’s Yinglong essence. Guided by their bond, grounded in the spirit key, and armed with the Fate-Severing Halberd, they sever the karmic chains of chaos and seal away the Realm Lord. In the end, they unite the immortal and mortal worlds, with the warmth of everyday life reaching to the highest heavens. The bond between the immortal maiden and Yinglong becomes the eternal protection of the Three Realms, forging an immortal legend: “Sever fate and shatter the wasteland; love binds heaven and earth.”
Love can reconcile life and death; mortal affection can break through chaos.
