In 2077, the Third World War broke out. Artificial intelligence defected, alien creatures invaded, and the human camp split. The world became a purgatory. I, Lin Che, accidentally awakened the [Tactical Deduction System]. I can predict the battlefield trend, analyze the enemy's weaknesses, and formulate perfect tactics! As a former top military king, with the blessing of the system, he swept through thousands of armies with iron-blooded tactics: using encirclement points to attack reinforcements to destroy the AI base, attacking east and west to kill alien leaders, and relying on vertical and horizontal alliances to integrate human forces! The stronger the enemy, the more excited I am; the more chaotic the battlefield, the more calm I am. Those who stand in my way will perish, and those who oppose me will perish! Let's see how I use tactics as my blade and system as my shield to fight my way through the chaotic world of doomsday, ascend to the throne of tactics, and take charge of the survival of mankind!
