When Li Yuanzhan first arrived in the Middle Tang Dynasty, he faced a hellish start:
At the top, the Empress Dowager controlled the government, while at the bottom, the Heshuo vassal town rebelled.
There are four major eunuchs who control the military power inside, and there are two parties, Niu and Li, who work together to attack differences.
This is the broken Tang Dynasty. Li Yuanzhan faces life danger all the time, so he chooses a steady path, but he is pushed to the forefront by the Empress Dowager.
He moved around a bit and regained his footing, but then he discovered:
His son coveted his power, and his uncle thought about conspiracy to rebel all day long.
This is the most brain-burning plot. Li Yuanzhan is treating the Empress Dowager as his grandson, but at the same time he is thinking about how to trample her in the mud; while he is romantically involved with the Queen, he is using each other with her; while he is loving and filial to his son, at the same time he is having a decisive battle at the Xuanwu Gate...
Machiavellianism, stability, military affairs, heroes, love, and poetry are all present, but systems, guns, railways, and steam engines are all bypassed.
