Courtyard: Sold Widow Qin at the Beginning

[Black revenge] + [High IQ layout] + [Technological power] + [Absolute self-interest] Wang Xuan, a top mathematics professor in the 21st century, died suddenly due to overwork and his soul traveled through the world of "Love in the Courtyard". The beginning was hell mode: he was seriously ill, his family was surrounded by walls, he was blood-sucked by the Jia family, morally kidnapped by Yi Zhonghai, violently threatened by Silly Zhu, and his original body was even forced to death! Facing the beasts in the courtyard, Wang Xuan pushed up the glasses on the bridge of his nose and raised a cold arc at the corner of his mouth. "In the eyes of mathematicians, you are just a bunch of erroneous variables full of holes." "Since it is a mistake, it must be erased." Step one: Using game theory and human greed, he set up a serial contract bureau to "legally" sell the vampire Qin Huairu into the mountains! Does Jia Zhang want to cause trouble? Criminal Law Warning! Silly Zhu wants to hit someone? The leverage principle teaches you how to be a good person! Yi Zhonghai wants to kidnap him morally? The closed-loop logic will leave you speechless! Step two: Starting as a technician at the Hongxing Steel Rolling Mill, Wang Xuan mastered the "National Deduction System". Using linear programming to optimize production shocked Soviet experts! Use fluid mechanics to improve military industry and let the Chinese saber be unsheathed in advance! Rubbing computers, igniting nuclear fusion, and planning financial wars... Some years later. When Wang Xuan stood on the country's highest technology podium, he was known as the "Father of China's Modern Industry." The courtyard house that was once full of calculations and viciousness had already fallen apart under his calculations. Yi Zhonghai sweeps the streets and regrets for the rest of his life. The stupid pillar is gone and his family is gone in his bleak old age. The stick is sitting in jail... Wang Xuan: "I have only done two things in my life: one is to kill the beasts, and the other is to strengthen China!"
