Gu Qianxue had no say over the matter of whether she should marry Xiao Luo. Gu Zhanguo had sent her to Mount Tianshan ever since she was a child. To her, Tianshan Elder was not only her Master but was also like a parent to her. Since Tianshan Elder wanted her to marry Xiao Luo, she would not object. Also, she had taken a fancy to Xiao Luo, so she naturally approved the decision.
Xiao Luo was also being persuaded by Xiao Quanren and Elder Long. His need to become attained greater strength and power left him with no other choice but to agree to the marriage. But he had some tricks up his sleeve. He planned to fake the marriage with Gu Qianxue, and it would be a marriage in name only. He did not want to disappoint or hurt Gu Qianxue.
Since both parties had finally agreed, that marriage proceeded!
