Xiao Che, the dandy marshal who was demoted to Malan City, and his 800 old and weak soldiers, faced a dead end of shortage of food and grass and barbarian harassment at the beginning. No one expected that this young man, who was ridiculed as a "weak young man", actually harbored a modern military thinking that subverted the times.
He used warehouse management to uncover corruption, relied on primary school mathematics to design traps, and defeated barbarian cavalry with three-stage shooting. In the first battle, he shattered the "waste" label. From the granary in the border town to the court hall in the capital, from the Hexi Corridor to the Haidong Islands, he built martial arts halls to break the monopoly of generals, made canned military rations to innovate logistics, cast bronze cannons to crush the grassland empire, and gradually implanted the modern military system into Great Yan.
The iron hooves of barbarians, the fall of powerful ministers, powerful overseas enemies, and the collision of civilizations. Xiao Che can always use incredible tactics to overcome the situation - detecting the enemy's situation with sign language, using the principle of leverage to build ballistae, and using gunpowder weapons to overturn the torrent of heavy armor. From a despised young commander to a god of war revered by thousands of people, he not only conquered the world by force of arms, but also left behind era-spanning war wisdom with "The Art of War". The foreign ship on the seaside carrying unknown weapons is a sign that a greater legend is about to unfold.
