2-dome no Jinsei, to Omottara, Jitsu wa 3-dome Datta.: Rekishi Chishiki to Naisei Doryoku de Fukou na Rekishi no Kaihen ni Idomimasu @COMIC

Takhir, a young baron, lost his beloved family and, powerless to prevent it, was branded incompetent. As he lay dying, his time-space magic suddenly awakened, restoring memories of a previous life and sending him back to childhood. No longer faltering before war or epidemic, he vows to use his revived modern knowledge to raise his people's level of civilization and change his family's fate. With knowledge of what is to come, he strives to reduce the devastation of poor harvests and floods while gathering talented individuals to strengthen the Solis barony. Acting without concern for the judgments of others, he aims beyond the Kair Kingdom, determined to alter history across the entire continent. Guided by his family-first principle, this child prodigy challenges his bleak destiny and sets in motion an unprecedentedly large rebellion.
