Although Mianmu Zuoniao seemed a bit erratic, she spoke quite logically, and Duanmu Huai quickly learned the whole story from her.
It all started when Inaba Tsukuyo came to find Duanmu Huai that day. At the time, she couldn't get any information from him, so she turned to Mianmu Zuoniao, who naturally refused to speak.
So, Inaba Tsukuyo communicated with her using the Five Swords method.
She and Mianmu Zuoniao had a fight, and she knocked Mianmu Zuoniao down.
However, although she was knocked down, Mianmu Zuoniao was never going to speak. But she did find a way around it, indicating that she couldn't say anything because she promised Duanmu Huai not to tell anyone. However, Duanmu Huai didn't say she couldn't take her along; if she really wanted to know, she could just come along and find out.
