18+ My Civil Servant Life Reborn in the Strange World

He was on his way to buy some beer to celebrate his acceptance as a civil servant when he was suddenly banged down and isekai’d by truck-Kun. Reincarnated as Denburg Blade, the son of a legendary battle race chief, he caught demons at 8 years old and a dragon at 12 years old. Subjected to the spartan-style training of his muscular monster of a father, he lived an inhuman daily life. “I must leave this place that is far from peaceful!” Safety is the best! So he chose to be a civil servant of the empire! Can Denburg really become a civil servant and live the peaceful and stable life he wished for?
