Shen Qingyue, a modern medical doctor, transmigrates into another world and becomes a lonely healer carrying the ancient spirit treasure, the Lotus Pearl of Recalling the Past. She crosses paths with Tang Ren, a battle-hardened general who protects the nation and secretly possesses the supreme temporal treasure, the Wheel of Cosmic Light. Strange cases plague the imperial palace, soul-corroding demonic poison runs rampant, and shadows gather around the mysterious Temporal Pavilion. Secrets buried for a thousand years slowly come to light: the two were once Lord Lingchen and Fairy Lingxi, guardians of the Three Realms. After the traitor Moyuan changed sides, they sacrificed themselves to seal him and fell into reincarnation.
To overcome their tribulation, the two treasures resonate, and the pair enter the Azure Cloud Immortal Sect, embarking on the path of cultivation and the pursuit of the Dao. They learn immortal arts, refine pills, break illusions, and suppress demons and evils. Moyuan closes in at every turn, while the Demon God of the Temporal Ashen Realm is on the verge of breaking free. The Three Realms stand on the brink of ruin.
She uses her cross-life compassion as a healer to save the world: one needle brings life back from death, one lotus purifies demonic miasma. He commands the order of time and space to keep her safe: one thought determines the fate of the world, one blade slays evil demons. Their immortal journey through Azure Cloud is long, and the flames of ash threaten to consume the world. Bound by fate across three lifetimes, the pair join hands with their twin treasures, making love their pact and the Dao their shield. They suppress the Demon God, avert catastrophe, and at last bring peace and tranquility to the mortal world.
