In addition to announcing Jing Yao as the Crown Prince, Emperor had also announced another royal decree.
The Chief Commander of the Pure Heaven Bureau, Zhang Yiai, investigated the case of the assassination attempt on Zhao Layue outside Zhaoge City by the order of the Emperor, and found it was a plot concocted by the Palace of Prince Jing Xin.
It turned out that Prince Jing Xin had hired the assassins of the Old Ones; it was an unforgivable evil deed.
This was something known by all; but the imperial court had announced this in public this time, and also presented some true or made-up evidences. No matter what, Prince Jing Xin couldn't stay in the palace of Prince any longer and had to go to another place, even for the house arrest.
Prince Jing Xin was sent to the Fruit Formation Temple to become a monk and
would pray there every day for the late emperor.
