Yao Ling thought that she could become cruel if she kept going to choose this path, but she felt an ache in her heart also guilt... But she also remembered how they became an easy target by these people. If she gave Qiu Qiu a way out and let her stay by her side, would she become loyal to her? She didn't think so. Qiu Qiu was different from Liu Li who had a twisted mind, so there was no guarantee that she wouldn't betray her once again. Yao Ling decided to harden her heart and in her heart, she already made an important decision.
She chose to protect herself and the people that she loved. Even if Heaven punished her, she didn't mind. Besides, there was no way out for Qiu Qiu --- her reputation was ruined and a lot of people already saw her disheveled state.
