Beginning: Lin Yu traveled to Peiping during the Republic of China, which coincided with the Japanese invasion of China. He witnessed the atrocities of the Japanese army and learned about the plan to move the cultural relics of the Forbidden City southward. By chance, he met Su Waner and learned some important information about the national treasure.
Development: Lin Yu, Zhao Tiezhu and others formed a treasure protection team. While evading pursuit by the Japanese army, they searched for and protected national treasures scattered throughout the country. In the process, they experienced countless difficulties and obstacles, and launched thrilling contests with Japanese spies such as Taro Yamamoto.
Climax: The treasure protection team learns that the Japanese army plans to seize a batch of important national treasures hidden in a secret location. They decide to take the initiative and start a decisive battle with the Japanese army. After a fierce battle, the treasure protection team successfully repelled the Japanese army and protected the safety of the national treasure.
Ending: After the victory of the Anti-Japanese War, Lin Yu and others safely returned the protected national treasure to the Palace Museum. They became national heroes, and Lin Yu also faced the choice of whether to return to modern times.
