In 2050 AD, "Qin Lie", captain of the Dragon Soul Special Aviation Brigade, piloted a sixth-generation aerospace fighter codenamed "Tenglong". During a top-secret test flight, he encountered time and space turbulence. Along with some of the wreckage of the fighter and the built-in "Tiangong Divine Furnace" system, he traveled to the precarious China of 1934. At that time, the mountains and rivers were in ruins, and the country was in crisis. Almost at the same time, "Gu Chen", a senior intelligence analyst of the National Security Bureau, accidentally touched a mysterious energy while studying a dusty top-secret file of the Neon State's invasion of China, and his soul possessed "Silent", a low-level intelligence agent who lurked in the Neon State's consulate in Shanghai in 1935.
