Ghost Songs, Mountains and Seas

The young man Fengyang grew up in the years of great disasters. His parents died young and were sold as slaves into a noble family's mansion at a low price by their uncle who had stayed with them for many years. By chance, he learned that the frail young master in the mansion had the same name as himself. He obviously died once, but was forced to reverse time and resurrected by the ancient gods. Looking at the young master's nameless grave, he decided to take over this identity and step into the cannibalistic aristocratic class.
