Reception
The series was generally well received in China, despite courting some controversy by changing certain portions of the novel for aesthetic purposes to reach modern audiences. Some antagonists, such as Yang Kang and Wanyan Honglie, also deviate from their counterparts in the novel, to the point that they are portrayed in a more positive light. Other significant deviations from the original story include: greater drama in the rivalry between Guo Jing and Yang Kang; the Yangs' troubled relationship with each other before they acknowledge themselves as family and Yang Kang's desire for vengeance after his parents' deaths; Yang Kang meeting his newborn son and raising the child with Mu Nianci months before his death; Yang Kang's final repentance before letting Ouyang Feng kill him. This resulted in criticism from the audience, who said that the series resembled a Chiung Yao drama where there are often unnecessary and exaggerated conflicts inserted into the storyline.
