Lin Mo, who was a down-and-out medical student in the late Southern Song Dynasty, gradually rose up with the help of the "Tiangong System", using medical skills as an edge and wisdom as a sword. In the desperate situation of the Jin Kingdom's cavalry and the powerful officials colluding with powerful organizations, he used modern thinking to reform the military, medical, and economic systems. He started a family-state game with his old enemy Han Mingyuan, and finally led the Southern Song Dynasty to complete military renaissance and institutional reform.
