Abandoned Forts as Flags

Lu Chen, the son of General Zhenbei, was intercepted and killed by bandits on his way into exile. After falling into a valley, he picked up half of a border defense map and discovered that the mastermind behind the scenes was a veteran Zhenguan general. He decided to use the abandoned military fort as a starting point to gather the refugees, crack the mechanisms, gradually regain the soldier symbols, and carve out his own way of survival on the dynasty's chessboard.
