Combining the real history of the Anti-Japanese War with the superpower of "Historical Echoes": After the protagonist travels through time or awakens, he has the ability to touch specific items (such as letters, bullet casings, maps, corpses) to hear the conversation of historical fragments that are deeply related to the item. These fragments are not complete information, but random, fragmentary, time-limited conversation recordings. The more times an ability is used, the more severe the damage to the brain's nerves, which may eventually lead to amnesia or collapse. The protagonist must make an ultimate balance between intelligence acquisition and self-destruction, and each acquired intelligence requires complex puzzles and logical reasoning to be used. At the same time, historical fragments can only play back the past and cannot predict the future. However, the protagonist can reversely deduce the opponent's psychological state and next move by analyzing the Japanese general's tone, word choice, and degree of hesitation in a certain decision-making fragment.
