Wang Ruiguang, a specially recruited recruit of the Southeast Military Region's Special Operations Brigade in 2026, is a "lazy" with extraordinary talents. As a global champion of tactical games, he has a photographic spatial memory, dynamic vision far beyond ordinary people, and a bug-level reconnaissance talent. However, he always likes to be clever and save energy. He is lazy and slippery during training and exercises, which causes headaches for the instructors. During a confrontation exercise between the Red and Blue Army, he accidentally traveled to the world of "Bright Sword" due to high-voltage electricity and accidentally entered Li Yunlong's independent regiment. In the war-torn era, Wang Ruiguang combined "laziness" with wisdom and used various lazy tactics to help the independent regiment repeatedly defeat the Japanese army. In the process of protecting his comrades, Wang Ruiguang lost his stubbornness and responsibility. After unexpectedly returning to modern times, he made a desperate comeback during an exercise and was appointed by the commander to form a special Falcon team to compete in an international special forces competition and win the championship. After that, he led the Falcon Squadron to the border, wiped out cross-border armed forces, and captured drug lord Kun Sa. He used precise and efficient "lazy tactics" to resolve crises time and time again and protect the peace of the border. He grew from a lazy and troubled recruit to a unique deputy commander of the special operations brigade, interpreting the wisdom and responsibility of the Chinese military's family and country in a unique way.
