The name "Wuqing Debt Collection Company" is edgy and on the nose. "Wuqing" means ruthless or heartless. The story plays it completely straight, treating it as a badge of honor. The bald fat man says it with such pride that it's almost comedic. I'm not sure if the author intends it to be ironic or not. But in this world, being ruthless is a sign of power. It's a typical xianxia/xuanhuan naming trope adapted to a modern setting.
The relationship between Emeria and Guilford is messy but interesting. He's her husband and father of her child, but he also abandoned her. I'm curious if they can build something real or if she'll escape again.
I'm getting major "underestimated protagonist" vibes from Ruby. Everyone treats her like she's worthless because her ability is "just" poison manipulation. But the pond scene hints that Poison User might be way more versatile than they think. The rats are also a sign – she can command poisonous creatures and they're loyal to her. If she keeps gaining followers (like the chick), she might build her own little army. Can't wait.
The fruits and vegetables with 60-80% purity being purified to 100% by the Green Lotus is a neat skill. I hope she starts selling those to solve her money problems.
The mood is overall light and comfy, but there's an underlying question of identity. The vampire starts doubting himself after the saint's warm speech. That moment of vulnerability makes him more human – even though he's not.
