"I thought you'd forgotten that today is the anniversary of your mother's death," the man said in a low voice.
Shangguan Yu lowered his eyes. "I wouldn't dare to forget."
The man sneered. "Then why didn't you make a move when there was such a good opportunity previously? You could have killed him immediately."
He was referring to the time when Shangguan Pu imprisoned the emperor. At that time, if he secretly killed the emperor, Shangguan Pu would definitely take the opportunity to rise to power. They could naturally stand up and expose his crimes.
"Shangguan Qingyu was saved in advance. If I attack, I'll only fall into someone else's trap," Shangguan Yu explained unhurriedly. "Don't underestimate Song Jingchen."
Shangguan Qingyu was the emperor's name.
