The most touching part of this story is that it cleverly integrates modern military knowledge with the history of the Anti-Japanese War. Through the setting of the "German Arms Ace Master" system, it not only retains the passion of the Anti-Japanese War theme, but also adds the innovation of scientific and technological elements. The most impressive thing is the dilemma and choice faced by the protagonist Zhao Tieying - the balance between system rules and guerrilla warfare principles. This inner conflict makes the story full of tension.
