The Executioner Scholar was originally someone from the Sword Saint Sect. Although he was a traitor to the sect, he was still very familiar with its situation and naturally knew about the plan to have those four servants block the sound. Hence, he concluded that if the Young Master of Sword Saint Sect wanted to kill Ye Qing, he would surely have those four servants block the sound while he goes alone to kill Ye Qing, thus increasing the chances of success.
It must be said that the Executioner Scholar was indeed very knowledgeable about the Young Master of Sword Saint Sect, having accurately guessed his plan.
He explained his conjecture, and Wanyan Hongsheng immediately agreed to the Executioner Scholar's method, as it was a once-in-a-lifetime opportunity. Not only could they kill Ye Qing, but they could also seize the items on him. In effect, it was a win-win situation for the Wanyan Family.
