A lazy bum transmigrates and marries a eunuch – it's awesome!

A strong female lead and a equally strong male lead + a ruthless, insecure yet arrogant male lead + a greedy and lustful female lead + a real eunuch + mutual pampering. Jiang Xinyu, a forensic doctor, was unlucky enough to be caught in the apocalypse right after graduating. After struggling to survive for three years, she died from the self-destruction of the zombie king. When she opened her eyes again, she had transmigrated into a book, becoming the eldest sister of the female lead, destined to be abused and die in childbirth. Jiang Xinyu was furious. Was a freeloader scumbag worth her time to fight in the inner palace? Get lost! It's just a wedding in three days, she can just find another groom. So, she set her sights on Xiao Yanwang, the head of the Eastern Depot, whom her neighbor's daughter absolutely refused to marry. Eunuchs are great, rich, handsome, powerful, and most importantly, they don't have to have children or serve their in-laws and follow rules. Too perfect...
