Ajie, a modern female doctor who has been reincarnated for nine generations, travels to Guangzhou during the Anti-Japanese War, and is followed by Kedi, a spirit turtle who can communicate spiritually. Proficient in medicine, she not only helped the world by hanging pots, but also was targeted by the Japanese anti-epidemic troops because she made her own penicillin. In order to rescue the captured people, she lurked in the enemy's hinterland and single-handedly turned the entire military police headquarters upside down. The big traitor also came to his senses when he saw her. Even the deputy commander of the military police became her little fan. Was the leakage of the top-secret Japanese military files on the Northern Guangdong Plan man-made or an accident? The smoke of gunfire, escape, life experience, conspiracy, and ancient mysteries are intertwined. In the chess game of troubled times, the long-lasting mystery of Brahma is revealed.
