Watching Sun Hui dodge away, Ling Tianyu smiled contentedly in his heart. As long as Sun Hui had dodged, the situation could still continue. Neither Wei Zifeng nor Wei Xiyao could be allowed to die. As for Yu Yue, whether he lived or died was a matter for later consideration.
He intended to use Sun Hui to draw out more people, ideally to lure out Wei Zifeng's birth mother, causing complete chaos within the Wei family.
If Wei Zifeng's birth mother did make an appearance, and if she brought Sun Aoyu with her, that would be even better. He could take the opportunity to make his move, and then he would be able to achieve his goal. However, it seemed he would not be able to find the Spiritual Liquid.
As for whether he could see who it was who had healed Sun Aoyu, if he could, it would be the best outcome; unfortunately, he feared he would not be able to do so.
