Book Nine by Yun Shui Ru Chan Xin

Shen Yan, a 35-year-old tycoon, transmigrates from 2026 back to 2010, returning to the beginning of the Ode to Joy story. Armed with knowledge of the next sixteen years of financial trends, the property market, and the entire plot, he has no intention of marrying and only wants to protect the women. From the start, he hoards Bitcoin, goes all in on promising stocks, and buys Apartment 2204 in Ode to Joy outright, becoming the neighbor next door to the five beauties. White Manager tries to deceive Yingying? He exposes him and serves up some face-slapping! The Fan family exploits Shengmei because they favor their son? He cracks down hard and puts an end to their schemes! Qi Dian schemes against Andy? He exposes his hypocritical nature on the spot! Ying Qin discriminates against women who aren't virgins? He tears into him until he questions his whole life! With immense capital as his shield and his foreknowledge as his blade, he rewrites all five women's tragedies and shatters the shackles imposed by their birth families and scumbag men.
