It is widely said that the king of Zhenbei, Xiao Yan, was ruthless, bloodthirsty and ruthless in his killings. The first three princesses all died tragically. The concubine Ye Qing was forced to marry in place of her eldest sister Ye Ying, who was pregnant and refused to marry. Ye Qing originally wanted to die, but unexpectedly after marrying into the palace, she became favored by Xiao Yan. When Ye Qing was pregnant with Liujia, Ye Ying regretted it and plotted to harm her sister to replace her as the princess.
