Mission-based transmigration: Modern-day heroine Lin Wan is bound to the “Save the Love-Struck” System and forced to transmigrate to ancient times, where she becomes Shen Wuyu, the original body’s owner and the Prince Regent’s consort. The System claims she must fix the original owner’s love obsession to extend her life.
Body-swapping pact: Shen Wuyu’s soul is trapped inside her body, watching as Lin Wan uses it to attract her husband, Pei Qingyan. When the System summons Lin Wan back to the modern world, Shen Wuyu must endure Pei Qingyan’s furious revenge. In the end, she uses seven talismans to initiate a “soul exchange” ritual.
A bookstore connecting all worlds: After Lin Wan returns to the modern world, she discovers that her ancestral bookstore can connect to other realms. The ancient books on its shelves are actually portals through time and space, and she must decipher their runes to return to the past.
Conspiracy of the Divine Kingdoms: The higher plane known as the “Twelve Divine Kingdoms” uses trials on a heavenly ladder as bait, siphoning energy from mortal emotions to maintain its rule. The System is actually a harvesting tool for the Divine Kingdoms, and the “Save the Love-Struck” mission is really designed to provoke extreme love and hate and extract energy.
Bond between twin souls: The souls of Lin Wan and Shen Wuyu resonate, forming a “mirror-like symbiosis.” If one is hurt, the other feels the pain too. The two eventually discover that they are the two halves of the same soul, split apart by the Divine Kingdoms.
