Siheyuan: I Sold Off Qin the Widow from the Start

[Dark Revenge] + [High-IQ Scheming] + [Building a Powerful Nation Through Technology] + [Utterly Self-Serving] Wang Xuan, a top mathematics professor in the 21st century, dies of overwork and transmigrates into the world of Love in the Courtyard. From the start, he's in hell mode: gravely ill, living in utter poverty, drained by the Jia family, morally blackmailed by Yi Zhonghai, and threatened with violence by Silly Zhu. His predecessor was literally driven to death! Facing the courtyard full of vermin, Wang Xuan adjusts his glasses and curls his lips into a cold smile. "In a mathematician's eyes, you're nothing but a bunch of faulty variables riddled with flaws." "And errors must be... erased." Step One: Using game theory and human greed, he sets up a chain of contractual traps and "legally" sells the bloodsucker Qin Huairu off to a remote mountain village! Jia Zhangshi wants to make a scene? The law will set her straight! Silly Zhu wants to hit someone? The lever principle will teach him a lesson! Yi Zhonghai tries moral blackmail? Wang Xuan traps him in an airtight logical argument until he has nothing to say! Step Two: Starting out as a technician at the Red Star Steel Mill, Wang Xuan gets his hands on the National Deduction System. He uses linear programming to optimize production, leaving the Soviet experts stunned! He applies fluid mechanics to improve military manufacturing, bringing China's military blade out of its sheath ahead of schedule! He builds computers by hand, ignites nuclear fusion, and lays plans for financial warfare... Years later. As Wang Xuan stands on the nation's highest technology awards stage, hailed as the "Father of Modern Chinese Industry," the courtyard once filled with scheming and malice has long since fallen apart under his calculations. Yi Zhonghai sweeps the streets, regretting his choices for the rest of his life. Silly Zhu dies without an heir, facing a miserable old age. Bang Geng spends the rest of his life in prison... Wang Xuan: "In this life, I do only two things: calculate the vermin to death, and calculate a stronger China into being!"
