Both Wen Qinxi and Qie Ranzhe had different ways to deal with Kai Zi and punish the wicked. As the saying goes there are many roads but one destination. Qie Ranzhe's method was ruthless but slow and Wen Qinxi's route was most definitely fast yet subtle. Each of them acted separately and that's because the overprotective husband put Wen Qinxi on 24/7 watch.
His actions implying that Su Xin should stay as far away as possible from trouble but Wen Qinxi eats trouble for breakfast especially after entering this game. So how could he obediently sit down and watch everything go to shit? Nope! Wen Qinxi managed to leave the mansion but this time he was so cautious he even wore a disguise.
