Thirty Nights with the Exiled Dragon King

Qinghe, a human historian, is sent down to a prison beneath the deep sea with a single assignment: document the life of Ao Chen, a black dragon king who has been banished there. The task forces the scholar to spend time with a figure the world has written off, and the account they are meant to produce carries weight for both of them. Their shared days in the watery stronghold push Qinghe to question what they were told about the exile and about the dragon himself.
