Great Yu: I Drew Lightfoot Skills from a Flower Thief at the Start

The Heavenly Prison is the dirtiest, most desolate place in Great Yu. Most jailers end up falling ill from overwork and meeting an unceremonious end. Su Yuxing wakes up there, afflicted with consumption and facing a bleak future. That is, until he discovers that he can see the debts of sin carried by criminals and draw strength from their deaths. The flower thief's light-footed movement, the rebel's swordplay, the demon's secret arts... all become fuel for his growth. He lies low, watching the lives and deaths behind the prison walls with cold eyes, while his cultivation quietly rises above everyone else's. When the demon-slaying agency's experts escort a terrifying fiend capable of bewitching minds into the execution chamber, Su Yuxing stands with his head bowed, looking like the most ordinary servant. No one knows that the blood and killing intent surging through him are like a volcano on the verge of eruption.
