Even a Minister Dares to Commit a Crime Against Someone Below the Monarch

[Two male protagonists + two strong men + two clean HE + seizing power + shady prime minister VS paranoid tyrant] On the day of the late emperor's death, Yan Jingze, the fifth prince, came to the mourning hall with a sword and forced all the courtiers to support his succession. The ministers were dissatisfied and after several rebuttals, Yan Jingze was completely angered. He killed the courtiers in front of the deceased emperor's spiritual throne. He was so ruthless and violent that everyone had to be afraid of him. After Yan Jingze succeeded to the throne, everyone feared him and was called a tyrant. The remaining forces in the court were divided into two factions. One faction supported the third prince in seizing power, and the other faction stood on the side of the fourth prince and opposed Yan Jingze. By then, Yan Jingze thought that no one in the court could be trusted. But he never thought that Suningchuan, the prime minister personally appointed by the late emperor, had been silently staying by his side to help him overcome obstacles, slowly warming Yan Jingze's long-frozen heart.
