Border Fortress Handbook. Side Story

The northern border collapsed and the nine borders were in danger! The barbarian iron cavalry broke through the defense line outside the pass, spies lurked in the court, rebellions continued, and food routes were cut off. The Ming border army was in a deadlock, defeated in every battle, and no one could break it. Everyone knows that Yi Jiuchou's hexagram steadies the smoke and stabilizes the frontier, but they don't know that it is a group of invisible border conspirators who really stabilize the dangerous frontier. He has no official status, no military power, and no name, but he holds a unique secret strategy and walks in the desperate situation of life and death. The enemy has thousands of troops, and I have a plan that goes against the will of heaven! Intercept the enemy's food and fodder, expose the spy network, kill undercover agents, and reverse the deadly situation. With the common people's wisdom, they can break the world's fatal battle. The army defends the city from the front, but they massacre in secret! The wind and sand cover up his name, and the troubled times hide his achievements. Behind every great victory is their bloodthirsty plan; every inch of the country they keep is a comeback from a desperate situation. No official history is written, no military exploits are recorded, but a secret strategy was used to pacify the deserted frontier thousands of miles away! This is the darkest, most bloody, top-secret secret battle in the Ming Dynasty's frontier fortress, and the one that dares not be recorded in the annals of history!
