Why did Xu Mansha kneel down? The reason is simple: she was terrified.
She had heard about flying artifacts before and even recognized that this flying artifact was very likely the Time Shuttle from Kunlun.
Feng Jun revealing the flying artifact and taking her to a desolate wilderness, what could possibly happen? It was very likely aimed to silence her!
Hearing him speak, she answered tremblingly, "Master Feng, I have never targeted you before, please show mercy."
It was actually Yang Yuxin who could guess what she was thinking. Hearing the words, she smiled, "Afraid of being silenced?"
Such words, logically, shouldn't be said by her. If the other party was silenced, what did it have to do with her? The dignified daughter-in-law of the Gu Family; shouldn't she just watch from the sidelines as events unfold? What if her words were inappropriate and she offended the cultivators?
