It is a sad and stirring story reflecting the assassination of the tyrant Yongzheng by jianghu righteous men. During the reign of Yongzheng in the Qing Dynasty, Daxing Literary Prison, many literati were killed innocently. In order to root out dissidents, Yongzheng trained the assassination group "Blood Dizi" and wantonly slaughtered folk righteous men. The anti-Qing organizations headed by former "Blood Dizi" members, Ma Teng and chivalrous Bai Tai Guan and Lu Si Niang, did not hesitate to sacrifice their lives and blend into the palace to fight to the death with many masters. Yongzheng tampered with the suicide note and won the throne. After ascending the throne, he not only eradicated dissidents but also carried out an inhumane literary prison, and many people were killed innocently. Yongzheng is also secretly training his own killer organization, Blood Dizi, to assassinate ministers and people who are dissatisfied with him. In order to fight for justice, the benevolent and righteous people in the rivers and lakes have secretly held assassination activities one after another have failed. Finally, Lu Siniang and others risked their lives to sneak into the palace, lurking around Yongzheng and became his trusted confidante. On the agreed night, the volunteers attacked Yongzheng's dormitory and were blocked by blood drips. At a critical time, Lv Si Niang put blood drops on Yongzheng's head and took the life of the tyrant.
