The protagonist Chu Tianze is a time traveler. He was once a top data analyst and was brought to the battlefield in 1944 by a rift in time and space. He can consume mental energy to construct an "event decision tree" in his mind, deduce all possible outcome paths for an event in the next five days, and find "the only and shortest path to victory" from them. This ability can only choose one path to deduce at a time, and the deduction result is absolutely correct, but how to "walk" to that path needs to be completed by the protagonist himself. Chu Tianze used this golden finger to move step by step in the enemy camp. He was both an agent and a master of analyzing the battle situation.
