In 1937, the land was shattered, and Japanese troops trampled across the Central Plains. A young man from the modern era accidentally transmigrates to the front lines of the War of Resistance, bringing with him a mysterious live-streaming System that can connect to the internet of the future. With nothing but his own flesh and blood, he records the battlefield as it unfolds, sending images of the defenders' steadfast resistance back to the present in real time and awakening the memories of hundreds of millions. In the live stream, soldiers charge fearlessly, civilians risk their lives to support the front, and women prove every bit as capable as men. Each battle embodies the dignity and defiance of the nation's backbone. Modern viewers send supplies through comments, pass along intelligence, and raise funds. Across time and space, they forge a path to national salvation. There are no superpowers, only the truth; no lone heroes, only a collective faith. In this spiritual resonance spanning more than eighty years, history is seen anew, and the heroes' names will never fade. The world is divided into two ends: one is 1937, engulfed in flames of war; the other is today, a day that remembers and never forgets. Connecting them is a signal line called conscience.
