In the seventh year of Kuang Yong, the third generation of Tokugawa shogunate generals, because of the implementation of centralization, weakened the power of many princes, and many of the once all-powerful samurai class became unemployed and became ronins. The cruel reality made idle ronins often go to the houses of princes to commit suicide, while the princes who were weakened and unable to recruit more ronins had to send them away with money, so this became a popular means of blackmail at that time. One day, a ronin named Qianyan begging for a daughter came to the well Yi family, and he also made the same request. The retainer decided to take care of the plan and let him cut his belly. As a result, Qianyan begging for a girl bit her tongue and died in great pain.

The reason is also the hardship of unbearable life, Jingyi family elder (Mikuni Rentaro is acted the role of) come forward. Before cutting the abdomen, Jin Yun asked to tell the story of his life.
