Qing Lingyan had witnessed Ling Chuxi and Chu Fengyun exchanging blows, and knew that Ling Chuxi's cultivation was definitely not weaker than hers. If this woman did not dare attack now, then she could not take action either, since she wasn't confident she could win against Ling Chuxi alone.
Thinking about it, Qing Lingyan could not help but regret. If she had known earlier, she would have gotten rid of Ling Chuxi back in Rejuvenation Valley without worrying about the repercussions. Her cultivation wouldn't have been as strong then, so it would have been easier to take her down! However, it was too late to regret now.
