The Heavenly Demon’s Debt Collector

Han Kang-Dae was a high-stakes debt collector for a Seoul crime syndicate. He was known for two things: never failing a job and having a joke for every broken finger. When he's betrayed and killed by his boss, he wakes up in the body of Young Master Shen, the "Trash of the Azure Cloud Sect," whose family was slaughtered by the righteous Orthodoxy.
