[Other plots are slightly sadistic + the main plot is sweet] The seventh prince of the Yan Kingdom, Murong Ming, has been sick and weak since he was a child, and has been under the protection of the prince Murong Jiong.
But one day, Murong Jiong was found a straw man with the name of the current emperor written on it.
Murong Jiong was imprisoned and tortured severely. He was asked to be executed tomorrow. Murong Ming only had one night.
So, he found the only witness at the time - Xu Jingqing, who was tried for killing thirteen members of the Yan family.
Only by overturning the case for the prince would Murong Ming overturn the case for Xu Jingqing.
But as the case develops, they discover that things seem to be far beyond their expectations.
In order to protect himself, Murong Ming had only one choice before him - regicide!
Intention: Sick prince VS cruel emperor, since you don't treat me as your son, then I will kill the king!
