Card Master of the Republic of China: I Defend the Country for China

Traveling through the card world, Resonance Ding, the initial card is thirty militiamen who don't even have names. The top students laughed at him as a useless person, and the great powers laughed at his civilization as having no future. It wasn't until his militiamen got through the fire attack, until he salvaged the first sealed military rule from the river - the world finally realized that what he held in his mind was not just a book, but an entire history of war.
