* * In order to protect the country's cultural relics, the anti-Japanese team of the Producer Party, Pan Lianchang and others moved all the cultural relics in the Xia Emperor's Mausoleum, but when they opened the tomb of the Xia Emperor's Mausoleum, they found that it was empty. However, in the death of Yukio Watanabe, his daughter Keiko Watanabe was robbed by bandits on the way to Ningxian to bring her father's coffin back to Japan. In the gun battle, Koch dodged a shot, but the bullet flew to Keiko Watanabe. Qiao Wenchong came to cover, but it was too late. Keiko Watanabe died unfortunately. After the climbing company commander learned the information, he disguised himself as the killed daughter of Keiko Watanabe and sneaked into the Japanese army in Ningxian. Just when the Japanese army found out the whereabouts of the map of Luoshen, in the evening, the Japanese army was ready to rob it, but it was secretly destroyed by Xu Yanyun who sneaked into the enemy's interior, and the enemy's two actions failed. At the same time, the Japanese army followed the clues and began to detect that there was a traitor, so it opened a series of searches. At this time, Xu Yanyun realized the danger and accelerated the pace of action. She noticed that the small building where Yukio Watanabe once lived had been blocked, and the road map drawn by Yukio Watanabe before his death should be hidden in it. The next day, the Japanese captured two anti-Japanese fighters, and when they were about to be tortured and interrogated, Yi Ming, a special agent at the mouth of the Yangtze River, thought that they could not escape from here? Instead of being tortured to death by the Japanese aggressors, they might as well ... After Yi Ming, a special agent at the mouth of the Yangtze River, directly picked up a gun and shot him, soon Xu Yanyun decided to take risks, and she secretly explored the building twice. For the first time, she accidentally alerted the Japanese patrol and had to jump out of the window in a hurry. The second time, she sneaked into the small building, just found the road map, but was discovered by Yiming, and took her out of danger from the tunnel before the patrol arrived. Subsequently, can Xu Yanyun successfully get the road map of the operation and drive the Japanese army out of Ningxian County? In the end, Yoshiaki Kawaguchi died on the battlefield of protecting national cultural relics.
