To help Kyoko, he just helps people who have been hurt in exchange for comfort without harming his own interests, which is easy. It can be said that her conscience has not completely disappeared.
This question is very difficult, and everyone has his own opinion. It's definitely not the pistol quality. It is Yaya's most proud work! I don't think with Mei Dong's wisdom, Yaya's betrayal will not be ignored. I guess she found it when she came to Kyoto from Yaya and Jiang, but she didn't show it. Judging from the power of self-explosion, someone must have tampered with that gun. Otherwise, how could the pistol be a "flying corpse at the scene"? People who cheat are either elegant or beautiful. Ya also can see from the article that Ya also wants to return to Meidong. Therefore, the self-explosion of the pistol should be unknown, so only Mei Dong did something. Of course, she will be so calm. Everyone who knew about her past is dead. He can really turn over a new leaf, and he is also the noble lady she dreams of. That's why it's like a magical night.
The whole novel can be said to be the history of Mei Dong's struggle. With her beauty and wisdom, she stepped on one person after another and climbed step by step. She is vicious, insidious, heartless and heartless. The biggest mystery of this book is the true identity of Mei Dong. I think her prototype may be the snow ear in Night Walk, a demon who only lingers in the dark at last.
