The Japanese learned that Hao Maoting's home had a Jun porcelain national treasure, the General Zun. Hao Maoting asked his daughter Hao Meizhen (played by Ping An) to escape with the General Zun overnight, but Hao Maoting and his wife were killed by the Japanese invader Katayama Gangyi (played by Chun Yu Shanshan). The servant Hong De (played by Wang Hongxiang) who was out on business witnessed the tragic situation of the owner. He had been serving in the Hao family for many years, and his chest was full of anger. He protected Meizhen to go to the grave of Hao Maoting and his wife to pay tribute late at night, but he was followed by Japanese agents lurking there.

Maruo Rinko successfully moved into Hongde and Meizhen's home. Can Hongde discover the coming of danger?
