Xing (played by Andy On) is a bloodthirsty, cruel and ruthless person. One day, he finally killed the emperor after coveting the throne for a long time. Not only that, he also tried to kill Princess Lian (played by Liu Yifei) and her brother Zhao (played by Su Jiahang). In desperation, the unarmed Lian took her brother on a journey of escape. Jacob (played by Hayden Christensen) is a brave and combative British knight. He came all the way to the Eastern country just to escape the painful memories of the past war. However, when Jacob was determined to protect Lian and Zhao, Jacob found himself once again forced to be in the center of the vortex of power and desire. In order to prevent his conspiracy from being exposed, Xing decided to completely eradicate the trouble. He not only offered a high reward for Lian and Zhao, but also sent fierce assassins to track them all the way.
