Another regressor type of story. But I like how he was successful in a peaceful world in the future, but he regressed because of some mysterious treasure he received lol. Bro was mad a bit ngl lol. Like why do I have to be a newbie again. But he still used future knowledge to improve things.
Also, surprisingly not a harem and there's only one girl interested in the MC. MC doesn't seem to be interested in her tho lol. Kinda funny and nice to see. Other girls have their own personality and are strong (*sob*)
