A 45-year-old delivery man accidentally traveled to Tianxuan Continent and practiced immortality for a thousand years. After Yuanying failed to survive the tribulation, he reincarnated into an 18-year-old Taoist priest in 1937. He saw the Japanese army burning, killing and looting, and in a rage he slaughtered the enemy invaders. He traveled all over Northeast China, Shanghai, Nanjing, and even set foot in Tokyo, composing a touching legend of the Anti-Japanese War.
