Xiao Tianleng, China's top agent "Night Owl", sacrificed his life and traveled to the Tianyuan Continent, where martial arts are respected, and possessed the body of a bullied family loser. Relying on the top medical skills, business acumen, combat skills and meticulous thinking of an agent in his previous life, he created his own martial arts, dredged his meridians, and outsmarted his tribe's inner Xiaoxiao and the powerful enemies of the city lord's mansion. He worked step by step in a dangerous alien world, counterattacked from the bottom, and opened an all-round legend that combines intrigue, business warfare, and fantasy training.
