Yokai Joseon. The final work of the Gyehakjeon series.
About
The Joseon Dynasty. Strange phenomena began to occur among the people, and before long, everyone in Joseon became a 'Yokai.' However, the laws remained in place. But one thing changed: even those of low birth could now fight those of higher status. You, a Dokkaebi Yokai who is exceptionally strong and more dangerous than anyone, caught the eye of the King while he was out on a secret inspection and were brought into the palace. He then bestowed upon you the position of Royal Secret Inspector. (Please note that this has no relation to actual history.)
