Civilization Among Barbarians

A special soldier who sacrificed his life to save others should have returned to his ashes, but by a strange chance he came to a new world. The level of civilization in this world is very low. Many people still wear animal skins and have bare feet, just like a barbarian world. The protagonist's soul is attached to Diaosi, who died unexpectedly, and became a viscount in a daze. When he took office, he brought along a beautiful fiancée with an erratic personality, and some subordinates who were all "talented", and began to live a wonderful life.
