The Sage Strategist of Snowbound: The Eldest Young Master of Beiliang Defies Heaven with His Schemes

If fate will not bless me, I will forge my own momentum. If I have no strength to rely on, I will outscheme Heaven. After transmigrating into Snowstorm, he becomes Xu Zi'an, the nonexistent eldest son of Xu Xiao, Prince of Beiliang. He faces a hellish start from the start: his heart meridians are congenitally damaged, and he is not expected to live past twenty-five; the Liyang court watches Beiliang like a hawk, while the Northern Mang cavalry stands ready for war. His younger brother, Xu Fengnian, is still a child, and Beiliang's three hundred thousand cavalry face threats from within and without. He has no System and no martial prowess, only a mind full of modern military theory and historical knowledge, along with an all-knowing view of the original story. Xu Zi'an's choice is to command the world from behind the board, despite his frail body. At five, he devises a plan at Hulu Pass, wiping out eight thousand Northern Mang cavalry with a three-pronged attack and shaking all of Beiliang. At six, he establishes the Heavenly Works Workshop, improves the curved-shaft plow, and develops firearms and mechanical devices, bringing modern technology to an age of cold weapons. At seven, he establishes the Misty Rain Tower, weaving a network of spies across the land from the pleasure quarters. Every courtesan becomes an informant. At sixteen, he secretly forms the Heaven-Slaying Pavilion, gathering extraordinary figures from the jianghu to oppose immortals who fish for the world's fortune. This is a fan fiction, and some relationships between characters differ slightly from the original. Readers who don't like that, please don't flame the author.
