Ten years ago, the Sun Family of the Chang'an Marquisate was exiled to the Northern Lands. Now, with the New Emperor's ascension and a general amnesty, the Sun Family is allowed to return to the capital. En route, Shen Fei, a biology Doctor and a klutz in daily life, experienced a laboratory explosion and transmigrated into a pregnant woman's body, unexpectedly becoming a mother. The Original Owner's premarital pregnancy with an unknown father brought shame to the family, resulting in her expulsion. Shen Fei and the infant stare at each other, wondering what to do. In these Ancient Times, she can barely support herself, let alone a child. Shen Fei decides to raise the child and find the child's father to take responsibility. What? Identifying relatives is difficult at this time? Not difficult, not difficult. Just give me a strand of hair, and I'll conduct a DNA test; the results are guaranteed. The child's father is found, along with his true Identity, uncovering a series of conspiracies. Shen Fei unexpectedly becomes Princess Rong. However, before she can enjoy her good days, she makes a shocking discovery: her infant is of extraordinary origins! On the day their true Identities are revealed, it becomes clear that debts, sooner or later, must be repaid! Father and son, son and father—it's unclear who is who! In short, Shen Fei becomes the most respected woman, someone no one dares to provoke. Shen Fei's inner monologue: This is a bit exciting!
