A modern military graduate student traveled to the Logistics Department of the Jinsui Army during the Anti-Japanese War and obtained a "three-dimensional strategic map system" that can display the battlefield situation in real time, combining modern war deductions with the real battle situation of the Anti-Japanese War. He did not dare and could not reveal his true identity. He could only use the vague identity of "fortune teller" and "mysterious informant" to convey accurate intelligence through the hands of others, and gradually established his own strategic influence in the cracks of various forces. He tried to use "intelligence leverage" to influence the direction of the entire war and save those teams that should have been sacrificed.
