Thanks for the chapter!
So the hair style and hairpin match so seems this woman is the last one of the four to appear from the cover pic. Granted the thug kicked the sister but I believe her when said sister in trouble, group out to kill her, and her women didn't beat sister up. Or at least everything said shouldn't be a lie, but what wasn't said leaves a lot of possibilities. Like reason why was sister bartending, who group is that attacked sister and why with intent to kill, why sister tied up with a abusive guard, is guard one of Zui's women or group's, and what Zui's position on matter is. Main thing I'd like to know is how sis had hands tied behind her back while MC was lifting guard by the neck one moment, and then next moment somehow clutching at him while trying to convince him to return?
In any case, she's probably interested in knowing more about MC considering his connection to her main rival the Ye family. Granted she probably wouldn't care if Ye family disappeared giving her a monopoly, but probably be pissed if Aunt Mei started making a mess of things and causing trouble or some upstart family like the Li family started grabbing power and influence while disrespecting her and her organization. After all, he saved Chenxi from an assassination and kidnapping attempt, cured Miss Ye from a poison Chi attack that would've killed her in a week, and has connections with the Tang family. So all this talk about his sister and dueling is probably taking his measure to see if he can back up what he says and his measure.
