The way he threatens Old Man Qin was savage. "A commoner's wrath, blood spattered five steps!" is such a classic line but it was so good in this context. The old guy tries to be slick and delaying, but Zhou Chen just pulls a knife and forces the issue. In a world without law and order, that kind of directness is refreshing and honestly, pretty smart.
The bit about Third Aunt Mo owing Lin Mu a favor because her son was in difficult labor - that's good writing. It explains why she'd help despite the obvious danger of dealing with a spiritually cursed baby. Everyone has debts in small communities.
I'm a little worried about the constant use of Yang energy transfers. The kiss, the back carry, the blood marks. It’s a bit repetitive. I hope the author finds more creative ways for Jiuyang to use his Daoist arts in future chapters.
