At that time, Dan Ah witnesses her father's death and flees in horror. Rebels try to capture her, but Jeok stops them, ordering them not to involve her.
During her escape, she encounters the head servant, but they are caught by the rebels. The servant gets killed, while Dan Ah gets injured in the process, witnessing the bloody chaos helplessly.
Bi Yeong Pal Mu captain Heuk Rang instructs his cohorts to save Hyun Bin and her baby princess; and the queen mother respectively. At that moment, he faces his former comrade, Mu Jin, in a death battle. Meanwhile, the paralyzed queen mother is left incapacitated in her crumbling quarters.
- The chapter's Korean title "화무십일홍" is equivalent to the Chinese proverb "花無十日紅" (Huā wú shí rì hóng), which translates to the chapter's English title. It also refers to the ebb and flow of life.
