I Possessed the Great Demon King

After transmigrating into the Great Yan Dynasty as its demon king, the Southern Emperor, Yang Tiancheng discovers a menu in his mind: a System that lets him increase his income and draw prizes using worship points.

Yang Tiancheng soon realizes that his empire is unstable and surrounded by scheming enemies. The only one who seems loyal to him is Shen Guang, a man from Wu Xing. Meanwhile, the men around him, including Wang Chong, Tiger Guard General Sima De, Pei Fei Tong, Yuwen Huaji, and Yang Su, will soon rebel and try to take his life.
