After Becoming Queen, I Will Be the Kindergarten Director in the Harem

I, a modern male kindergarten teacher, sacrificed my soul and traveled through the Five Dynasties and Ten Kingdoms, becoming Zhang Tiezhu, a butcher with chest hair thicker than leg hair. I cried when I saw my fiancée who could kill a cow with one punch and four brothers waiting for dinner. Troubled times are coming, so I have no choice but to return to my old business - running a kindergarten! Use love to influence the refugees and use rules to manage the army. When my "love value" system became popular all over the world, my old enemies rushed to send their children to school. They call me the one who fights the hardest battles with the softest heart - the tender overlord.
