A 22nd-century secret agent, Ji Yunshu, accidentally transmigrated into a novel, becoming the cannon-fodder princess consort who had just married the Prince of Zhenbei, Xie Meyao. What's even more absurd is that her fate was bound to this heavily injured prince; in order to survive, she could only figure out a way to protect him first. Yet on the second day of their grand wedding, the Prince of Zhenbei's mansion was raided and its occupants sent into exile. Ji Yunshu activated her portable dimension space, transferred the mansion's supplies ahead of time, and took back her dowry that had been usurped by her maiden family. While others suffered from a lack of food and clothing during exile, she relied on her space to resolve crises all the way; facing framing and harassment, she never backed down either. Protecting the prince, safeguarding the Xie family, investigating old cases, and fighting against powerful nobles all the way, she stubbornly turned a sure-to-lose starting scenario into a counterattack comeback journey.
