But his attempt cost his mother's life.
It was extremely painful and bloody.
The situation in Wei Da Kingdom was unstable with various infighting and also countless battles outside.
That battle for the throne involved him.
Yu Zheng Xi had to participate even if he didn't want to. He hoped that he would be able to protect his mother and aimed for power.
But he failed miserably.
He was not suitable to be an Emperor and all.
From his defeat and so on, he was angry and frustrated.
At the same time, Yu Zheng Xi knew how ridiculous it was for him to challenge the entire Imperial Family. He could only kill those who hurt his mother and involved in this matter. After he was done, he left the Capital City and was pursued by a lot of soldiers because of his background and his deeds.
The other Imperial Family members couldn't wait to go after him and make sure that his entire body was dismembered.
They wanted his life.
