Tang Hao revealed a self-mocking smile.
"I never thought that little brat from back then would possess such strength so soon. Sure enough, when you awakened your martial soul at six, I should have paid more attention to you. When you were fifteen, I should have eliminated you regardless of the cost, instead of fearing that old dog Qian Daoliu and letting you live until now."
Naturally, Qian Renxue could not tolerate Tang Hao calling her grandfather an "old dog." She immediately threw a punch at him. As for Mo Lin, Tang Hao was still useful to him, so naturally... he did nothing.
That was right. Not only did Mo Lin not try to stop her, he even secretly loosened his grip, allowing Qian Renxue to smoothly break free from his right hand and punch Tang Hao in the face. By the time that brief moment had passed, both Qian Renxue and Tang Hao were somewhat dumbfounded.
Qian Renxue had genuinely wanted to hit Tang Hao, and it had indeed felt satisfying when her fist landed. But after calming down, she was very surprised that Mo Lin had not stopped her. She knew full well that her actions had been extremely emotional. Normally, if an onlooker had the ability, they would at least try to stop her. Mo Lin could clearly have grabbed her and made her calm down, then said something like, "Don't get angry with someone who's about to die," or, "I have harsher methods," to soothe her anger. Yet he had done nothing.
Before Tang Hao was solidly struck by Qian Renxue's fist, he had thought that Mo Lin had not killed him outright because he still needed him alive. Therefore, Tang Hao believed Mo Lin would do everything possible to minimize any unnecessary harm he suffered.
