An ordinary office worker who lived an ordinary life had a heart attack when he was about to go to work one day. When he woke up, he had become "Ars", the legitimate son of a weak noble family in another world. Ars was still ordinary in this world, but he had the ability of "identification" that could convert other people's abilities into numerical values. After learning that his country was about to break out in a war, Ars decided to use his "identification" ability to recruit outstanding talents everywhere in order to survive and protect his territory and people, and build a super territory from scratch!
