Qingli, a saint of the witch clan, and Xuan Xiao, the young master of the Demon Suppression Department, became connected because of their pursuit of the deer demon. However, they encountered great changes when they sealed the ancient demon king. Xuan Xiao was eroded by demonic energy and fell into darkness. Qing Li was willing to be tortured by bone-gnawing whips and forced her way into the forbidden area. Using the blood of the phoenix as a guide and the concentric lock as a contract, she gained the chance to reverse life and death in three days.
In the Demon Suppression Tower, the boy who used to protect her with a sword has become a demon puppet covered in demon patterns. His left eye is scarlet, and his fingertips are condensed with a cold blade that has killed thousands of demons. The red rope between Qingli's wrists burned inch by inch, and the prophecy of the fall of the first generation of saints three hundred years ago emerged in the blood light - it turned out that the half of antlers and jade hidden in the lock core was the key to rewriting fate.
When Xuan Xiao's demon-conquering pestle pierced her heart, the demon king revealed his true form while laughing wildly, but little did he know that the blood of the two of them had already been soaked in the ancient marriage contract. The golden and red lines and the silver-gray demonic lines fight like old enemies, and eventually become an everlasting red thread under the ginkgo tree.
From the fireflies in the Deer Ming Stream to the flames of the Burning Heart Technique, from the bronze coffin in the blood vine forest to the smoke-filled courtyard a thousand years later, they use their souls as torches to illuminate the darkest lies in the three realms. The sharpest thing in the world is never the order to subjugate the demon, but the half piece of wedding candy that the girl clenched tightly when she was tortured. It was the last concentric knot that the young man tied for her before his white hair fell away.
