The play is based on Haiyan's online novel of the same name, and the historical facts are the Northern Wei Dynasty, the Eastern and Western Wei Dynasties and the Qi and Liang Dynasties in the Southern Dynasty.

However, this work is an overhead history. Even if history crosses categories, the countries, people and events described have nothing to do with historical facts.

In other words, the content of this book is YY. If there is any similarity, it is unfortunate.
