It mythifies and fictionalizes the lives of Văn Dĩ Thành and Lê Ngộ, the leaders of a Vietnamese resistance during the Fourth Era of Northern Domination.

[1] The Tale of the Yaksha General is the twentieth and final story of Nguyễn Dữ's Truyền kỳ mạn lục collection,[2] published in the fourth volume.

At the end of Trùng Quang Đế reign, people die en masse and their spirits become hordes of wandering demons running amuck.

One day, a messenger from the Underworld appears and informs Dĩ Thành that Yama wants to appoint him the general of a Yaksha division.

Although the purple-robed man is unmoved, the fellow demons convince him to spare the human, so he removes Lê Ngộ's name from his book and his family recovers.
