When the protagonist Shen Yue is surrounded by heavy Japanese troops, a "battlefield deduction system" awakens in his brain, which can directly quantify all factors such as the army, terrain, and logistics into real-time victory rates, and simulate different tactical trends. But the winning rate he saw was "theoretical value without considering the asymmetry of information and luck." To truly win, he had to personally execute those incredible tactics - using cavalry to charge tanks, using firecrackers as artillery, and having the cooking squad disguise themselves as the main force... Every extreme operation after precise calculations is a strong satisfaction to the readers' expectations.
