As mentioned in the TV series, the messengers of the underworld are all people who committed heinous crimes in their previous lives, so the crime committed by Wang Li is to kill Jin Shan and her brother under the temptation of a traitor, which is a ghost in reality.

Jin Shan was originally Wang Li's favorite woman, but was later framed and killed by traitors. After Jin Shan's death, Wang Li couldn't get over the pain, so when he knew that the mole had poisoned himself slowly, he pretended not to know until he was finally poisoned.

After his death, Wang Li became a messenger of the underworld because of his heinous crimes, and he lived a long life. Later, he met Sang Ni. When I first met sunny, she saw Princess Koryo's ring on the stall. The messenger of the underworld shed a lot of tears unconsciously at this time, which shows the deep bond between the two.
