The trilogy is Loosely based on the classical fantasy novel "Investiture of the Gods" (Fengshen Yanyi) by Zhonglin Xu and Xixing Lu, which is one of the only two mythical epics in Chinese literature history that originated from real historical events, and was greatly enriched and fabricated with vast imagination and fiction, when it was passed down the generations by storytellers over the last two thousand years, and finally became a classic. All materials came from local Chinese history and culture. It is arguably the No.1 mythical fiction of China.
