Many girls only consider marriage when they feel they are no longer making progress in their cultivation.
Bian Shasha never thought that becoming a woman could increase her cultivation, even more effectively than consuming several high-grade pills. Had she known this earlier, she would have chosen to marry sooner rather than come to the Boundless Forest to be with this man, who looks to be in his thirties and speaks like an old man.
Now that it's too late for regrets, she could only wait for fate's arrangement. Bian Shasha made up her mind to learn his cultivation technique, already unable to turn back, so when she was capable, she would escape this man's clutches and somehow find a way to kill him.
If she couldn't kill this man, she still had to escape. Life had taken a turn, and her dream of Prince Charming might become unreachable, with Lai Jianlin perhaps forever hidden in her heart.
