"Yiting'er, do you remember Du Yu?" Xie Ming Yu suddenly asked Yang Yiting.
On this day, the two were checking the roster of students enrolled in the past two years in one of the Pavilions of the academy.
"The son of Du Yuan, the Minister of Foreign Affairs? The one who disappeared a few months ago?" Yang Yiting thought for a while and replied. She remembered at that time, there was a Wuji assassin who committed suicide on a major street in the capital. The man who faked his identity as Du Yu.
"Exactly." Xie Ming Yu nodded. "Strangely, he came back ten years ago, but couldn't remember all of his disappearances in the past few months."
