"The Majestic Yama of Beiliang" tells the legend of Xu Jin, the "Yama" of Beiliang. Due to the mystery of his life experience, he went to the ancient altar of Xueyuan and was drawn into the rift in time and space by the power of runes. He traveled to modern Jiangcheng and took over the body of young Chen Mo.
In the unfamiliar modern society, Xu Jin went from being at a loss to becoming a community security guard. He met Lin Wan who was suffering from domestic violence by chance, and showed his bravery in Beiliang when he captured the thief. During the exploration, he discovered that Chen Mo was closely related to his dreams and altar runes, and was actually his cousin. The mysterious organization "Shadow Pavilion" was coveting the time and space power of the runes, and was pressing on him step by step to snatch the "Gubeiliang Rune Research".
As the clues intertwined, Xu Jin uncovered the truth: the Xu family is the guardian of the altar, guarding the rift in time and space for generations, and the Shadow Pavilion wants to make money from this. In order to protect the altar and find Chen Mo, he returned to the snowfield, met his old friend Lao Scar, and had a final showdown with the Shadow Pavilion at the altar, awakening the power of the altar guardian to close the rift.
The story combines the iron blood of Northern Liang with modern weirdness, showing Xu Jin's transformation from "Yama" to a guardian, leaving behind suspense such as Chen Mo's trace and the counterattack of the Shadow Pavilion, and outlines a legend of responsibility and redemption that spans time and space.
