[Sweet romance, transmigration, flirtatious and steamy, powerful leads, mutual devotion, both leads are each other's first and only, happy ending] Business queen Meng Sujin suddenly dies, only to transmigrate into the body of a lowly slave locked in a cage in ancient times. A disastrous start, but the dashing hunter Gu Yu saves her. A business queen turned hunter's servant, she refuses to accept her lot. She picks up her old trade and vows to rebuild her business empire in this wild frontier. She clears land and farms while he quietly protects her. As she navigates the business world, he removes every obstacle in her way. They spend their days close together, whispering sweet nothings, and are more or less content with their life. Until one day, enemy forces close in and the state teeters on the brink of collapse. Meng Sujin packs their belongings, ready to drag her man away and flee Only to see the hunter who has spent every night entwined with her slowly don armor patterned with golden dragons, while a million iron-clad cavalrymen stretch out behind him like a sea of mountains… Meng Sujin stares at the man before her, his commanding presence on full display, utterly stunned! “Who are you, really?” Gu Yu takes her hand, his gaze profound. “I am not Gu Yu. I am…” From Gu Yu's perspective: I am a man who has lived for more than a thousand years. A thousand years ago, I committed a grave sin and was punished by Heaven. I am immortal, but I am forbidden from touching women for all eternity. The moment I do, Heaven's punishment falls upon me. At a market, I bought a female slave and discovered that I could touch her! To uncover the connection between her and me, I brought her home. Her arrival lit up the lonely heart I had carried for a thousand years. She said she was a woman who had transmigrated, and I believed her. A thousand years is long and dull. After meeting her, all I want is to lose myself every day in her sweet moans, drunk on pleasure and oblivious to the world.
