The three great sects coveted the power of the Fire Seal and caused Zhang Yingying's parents to be killed. Before dying, her father sealed the power of the Fire Seal inside her body. Seriously injured, she was taken back to the Tianheng Sect by her older brother, Zhang Yaowu. However, she was ostracized by the sect leader and fellow disciples, making her life extremely difficult. Fortunately, her brother Zhang Yaowu always protected her.

With the sect on the verge of destruction and her brother Zhang Yaowu nearly killed, Zhang Yingying could no longer hold back. She unleashed the power of the Fire Seal and turned the tide.
