Transmigrated as a Cannon Fodder, I Became the Military's Beloved Darling

【Alternate-Era Setting + Transmigration + Pocket Dimension + Everyone's Favorite + Revenge on the Villains + Marriage First, Love Later】 Lin Shuyu, a PhD from an agricultural science institute, woke up as a cannon-fodder supporting character who wouldn't survive three chapters. In the book, the original owner would rather die than take the heroine's place in an arranged marriage. In the end, she was not only tormented to death, but her corpse was even used in a ghost marriage. After transmigrating into a book, Lin Shuyu said she was willing to take the bride's place, but only if the money was right. And she wanted her family's heirloom jade bangle back, too. In the book, the stepmother gave the jade bangle to the heroine, who used it to unlock a spiritual spring dimension. Why should Lin Shuyu let someone else profit from what belonged to her? When her stepsister teamed up with her stepmother to frame her, Lin Shuyu hit back by sending the heroine to the countryside and the stepmother to jail. So what if the man was a twice-married older guy with a child and no chance of having more? Lin Shuyu wasn't afraid. Having a child was great. She could become a mom without the pain of childbirth. No chance of having more children? Ahem... As long as it didn't affect the other thing, she was totally fine with it! An older man... knew how to treat a woman right! She took the daughter she'd gotten for free with her to join him at his military post. The moment she arrived, she was stunned. This older man wasn't just the most sought-after bachelor in the military. He was handsome, had an eight-pack, and was a devoted family man. This bargain... would be a shame to pass up... One day, Lin Shuyu stared at the pregnancy test in her hand, bewildered. Weren't you unable to have children? Gu Tingzhi... It turned out that in the explosion five years ago, a fellow soldier had died, and newborn Niuniu had been left at the military base's front gate. Gu Tingzhi had adopted her... So the twice-married older man was actually still a first-timer?
