I always feel that the messenger of hell played by Lee Dong Wook should be the king. He actually loves the empress (the general's sister) played by Kim So Hyun, but he was bewitched by a traitor and killed the person he loved the most. Passed away, and later erased his memory and became a messenger of hell. In the first episode, when the general became a ghost, the sword was rusted and the traitor's black beard turned white. It can be seen that what was wrapped was the deceased king. At that time, the king should have grown up to the age of Li Dongxu. role. And Liu Renna is the reincarnation of the goddess, because there is a scene in the trailer when Liu Renna picks up the ring of the goddess, and the messenger of hell looked at the ring and shed tears. This is a brain hole I guessed after watching two episodes. If this is the case, there will be more entanglements between the ghost and the messenger of hell.
