Deviation from novel.
In the novel, Wu Xie is the owner of an antique store but in the series, he is an overseas returnee who studied at a German University and returned to China to return an antique to the country. The rest of the team also became "protectors of the antique" instead of a "tomb-raiding team". 
Two new characters, High Master and Cheng Chengcheng, were also created for the web series.
Reception.
