Shen Yanzhi, the newly appointed soldier, is a scholar who only knows how to "settle accounts".
The first thing he did when he took office was to open the "People's Livelihood Account Book":
"Food, three hundred stones of horse feed, can live for ten days. Arrows, one thousand two hundred, to defend the city for half an hour. Soldiers, including the old and weak, eight hundred people."
"And Beishuo Iron Cavalry, five thousand."
People in the city regarded him as crazy, and people outside the city wanted to take away his last spoonful of horse porridge.
But he wrote in the account book:
"1. Use ice slopes in exchange for war horses to get meat and skins. 2. Use horse hides to make paper armor, which can save 90% of iron. 3. Use 'dead man's rice' to recruit bandits as soldiers, cost: one waist card."
He calculates the price of grain, the consumption of arrows, the price of human hearts, and the price of broken hearts.
Colleagues wanted to check him for "violating the rules" in the court, and Beishuo Khan accused him in the tent of "not getting rid of troubles."
This is a war without miracles.
Every victory was clearly priced and written in his account:
"Yunguan defends the city and wins. Pay three hundred lives and the granary is at its bottom."
"Jinghua reverses the verdict and wins. Pay ten years to clear his name and get a new grain road."
"Yanmen saves the siege and wins."
When the dust settled, he handed over the military talisman and presented a full "People's Livelihood Account Book" to the emperor:
"My lord, Shen Yanzhi, the Northern Territory Protector, will leave without any regrets.
I only hope that Your Majesty will take another look. Behind every number is a human life or a grain of corn. "

Hard-core historical conspiracy, no system, no time travel.
There is only one account and one person who can calculate to the extreme.
