Gu Zhi, a graduate student in warfare, woke up and became the chief scout of the Northern Army in the Northern Territory—charged with collaborating with the enemy. The evidence was a secret letter that he had not even opened the sealing wax. Tomorrow at noon, the head will be beheaded in public display.
On a rainy night, there was a riot on death row. He killed the jailer, seized the waist sword, guarded the north gate with twelve defeated troops, broke the bridge and burned the formation, and killed Han Duwei's three hundred cavalry. From death row prisoner to city defender, it only took one night.
But this is just the beginning.
Behind Lieutenant Han is the hidden stake network of Beidi Royal Court, Heishizhai has three years' worth of grain, grass and weapons, and there are five Beidi codes hidden within the Zhenbei Army. Tuoba Ye's 300,000 cavalry will go south in a month.
Thirty defeated soldiers, a half-ruined fortress, and a poisoned wound. Gu Zhi has a war chess sandbox in his hand, which can deduce the world's war situation - but the sandbox only provides deductions, not resources. He must personally train troops, farm fields, open mines, and forge cannons. He must feed his soldiers with the enemy's food and arm his battalion with the enemy's ordnance.
From a death row prisoner to a thousand households, from an isolated village to the three states, from a border town hero to the founding hero.
