I Took Down My Ex's Rich Heir, Then the Cannon Fodder Packed a Baby and Joined the Army

Mechanical research genius Jiang Yayan transmigrates into a novel set in a bygone era. The original owner was locked in a cattle shed by her in-laws and starved to death while trying to imitate a devoted mother’s care for her child. Only then did she learn that the “younger sister” mentioned by her scumbag capitalist husband, Lu Mingzhou, was surnamed Lin, not Lu. She was, in fact, his first love. The original owner looked like Lin Sangsang and was nothing but a disposable stand-in. So Jiang Yayan swallows a fertility pill and decides to find a biological father for the child in her belly. She beats Lin Sangsang until she’s howling, takes out the scumbag, and empties the Lu family’s coffers. Then she unexpectedly discovers that a safety pendant unlocks a reward pool. Trade a small ivory hand mirror with carved flowers for a nanometer-scale suit of armor! Trade gold earrings set with large pearls for a 2nm lithography machine!

There are also nuclear submarines, quantum computers, antimatter engines… With so many technologies and machines, what if they don’t fit the era she transmigrated into? Then she’ll quietly do good deeds without taking credit and donate everything anonymously! ***When Fu Rongchen’s fellow soldiers meet Jiang Yayan, they’re more delighted than shocked.

She can fix gantry milling machines and even tanks!
