Retribution!

The following morning, before the sun had a chance to rise, a solemn assembly congregated before the Main Palace Hall within the royal palace. Their purpose was to bear witness to the ultimate departure of Yang Lingxin, who had been accused of treason and conclusively shown to have attempted the assassination of His Majesty. 

Not only was Yang Lingxin proven guilty of administering slow poison over an extended period, but it was also established that he continued to do so while His Majesty lay sick and on the verge of death.

To offer their final farewell to the Empress of the Empire, who had shamefully transitioned from a revered figure to a traitor, the Crown Prince and all the royal ministers gathered for the somber assembly. Upon receiving the unexpected news of Yang Lingxin's abrupt departure, Yang Ning too felt compelled to attend, motivated by a blend of curiosity and a sense of duty.
