Counterattack on Jinling, 1937

Yang Chengyu, a modern extreme-sports enthusiast and retired soldier, transmigrates after an accident during a survey of ancient architecture, when he touches a mysterious bronze fragment beneath Nanjing's Ming-era city wall. He awakens a “superhuman constitution”: strength beyond human limits, with punches reaching 1.5 tons; speed comparable to a cheetah, covering 100 meters in three seconds; and extraordinary self-healing, with nonfatal injuries healing within 24 hours. He also has a photographic memory, basic combat skills, and first-aid training.
