It's been 25 years since the apocalypse, when the world we knew changed forever. It was then that terrible monsters appeared and some of humanity evolved to fight them.Seraphine a 18 year old citizen in Newber, was living a peaceful life with her parents, learning at the Academy, to get a nice job within the government. At least, until everything turned for the worse and she ended up as an Evolved in a destroyed city.

Wenyan read a book in which a cannon-fodder character sharing her name was a false heiress. After the true heiress assumed her position, the impostor tried to secure her place in the wealthy family by drugging the eldest son and making a done deal out of a cooked rice, only to be unmasked by the Shen Family and end up committing suicide in despair.Wenyan was furious to see such an ending. How could one not survive without the backing of a wealthy family? Hadn't the family provided her with a luxury house and countless luxury goods? Just selling those off would fetch tens of millions. She was just a hopeless case!If she were the Wenyan in the book, she would have relinquished her position and just lived laid-back like a salted fish!But when she woke up from her sleep, she actually transmigrated into the book. True to her word, she stopped scheming. Overnight she packed her bags, sold her house, car, and bags, and looked for a job.The entire Shen Family noticed the change in Wenyan, their adopted daughter. Not only had she moved out obediently, but she also never caused any trouble again. Even more bizarre was that they could now see her innermost thoughts!【Dad, Mom, I never wanted to usurp your nest, but the DNA test results of the true daughter have issues. In fact, she's even more fake than I, the bogus heiress.】Shen Family parents: ...... Then the long-lost 'daughter' who had been found was exposed as an impostor and taken away by the police for questioning.【Big brother, that schoolmate of yours is no good, he's a corporate spy, the illegitimate child of the Shen Family's archenemies.】Shen Family's eldest son: ...... Afterwards, the schoolmate got caught stealing confidential documents and was also taken away by the police for questioning.【Second brother, you are such a pure and noble person, you mustn't be with the Qin Family's daughter, she's just using you, her heart is actually set on someone else.】Shen Family's second son: ...... Thank you, I'll look into it.【And third brother, fourth brother......】In the end, nobody could have predicted that the Shen Family's most undistinguished adopted daughter would become the pampered daughter-in-law.
