Lin Yan was trapped by the Immortal Jump when he crossed over and was demoted to the barren Yunhuang border town. The emperor wanted to trap him for the rest of his life, and all the courtiers made fun of him.

The emperor on the dragon throne was deeply regretful, but Lin Yan's sharp edge had already overwhelmed the government and the opposition.
