绝命卦师：太后祸乱后宫，趁皇上不在皇宫杀皇子，让六儿子登皇位

During the "Tu Bu Bao" incident in the Ming Dynasty, after the emperor personally marched to the border and left the palace, strange incidents occurred frequently in the harem. The cultivator Tianmu Tong (played by Zhang Xiaochen) was ordered to enter the palace to capture demons and investigate the love and hate between him and eunuch Xiaomu (played by Zhang Haoran) and the female leader of the Jinyi Guard, Yun Xiangrong (played by Lu Anjie).
