This is a story outside of historical records around the time of Zhenguan.
For example, there were more than six departments under the three provinces of the Tang Dynasty, and there was also a seventh department - the Military Department.
For example, the Qiwu people have never appeared in history books.
For example, the Duwu Division specializes in suppressing the Qiwu people.
For example, after the Xuanwumen Incident, Li Jiancheng and Li Yuanji did not die, but instead sparked another bloody storm.
For example, the most evil organization that lasted from the Warring States Period to the Tang Dynasty - Zhenwuhui.
Historians say that the Zhenguan reign was the first reign of the Tang Dynasty, but in fact it was the darkest dawn of the Tang Dynasty.
