From Yuan Wenye's perspective, Si Jin was targeting the wizard, which had nothing to do with him and he didn't want to be dragged into trouble.
However, Si Jin targeted both of them, so it was impossible for her to let Yuan Wenye run away.
Therefore, the moment Yuan Wenye moved, Si Jin grabbed a chair and hit him.
The next moment, the chair hit Yuan Wenye causing him to scream in pain. Then he fell to the ground. Because of the sharp pain, he couldn't get back to his feet.
Si Jin turned back to fighting the wizard, while paying a little attention to Yuan Wenye, in case he ran away.
The wizard realized that he was no match for Si Jin, so he wanted to use poisonous magic. Unfortunately, before he could, Si Jin directly ruined his plan.
Si Jin used magical energy, so she was quickly able to defeat the wizard. The wizard was seriously injured and both of his hands were disabled.
