The Campaign Against the Northern Barbarians

A top internist transmigrates by a stroke of fate to a parallel universe.

He goes from a highly skilled modern professional to a useless man who can’t even dress himself, his body already utterly depleted.

Unwilling to sink into despair, he devotes himself to learning.

He battles corrupt officials and brings disasters under control.

At last, a great master takes a liking to him and teaches him the art of war.

From a good-for-nothing, he becomes a gifted scholar and warrior, a pillar of strength in the fight against foreign tribes.
