He should have made sure toothpaste exists in that world before giving them all that sugar.

This has so much potential but all that is happening is product showcases and a speck of romance

Thank you for the scanlation

Ah, matches. Right up there with mayonnaise on the isekai checklist.

He can make a gatling gun, history has L I T E R A L L Y shown us what that means. Not to mention how by making a rifle he should be able to outrange most if not all people on the continent after some target practice. Those chumps hiding in the forest are toast.

Matches reminds me of that other merchant isekai lol

But given how much they like sweets surprised he didn't rent out part of a bakery or collab with them or so lol

Dunno why that guy shouted in surprise when he introduced himself as a 'merchant' unless he meant a more permanent store rather than setting up a carriage/stand

He should have made sure toothpaste exists in that world before giving them all that sugar.

I think isekai pharmacist is the only one that ever mentioned cavities but that would be interesting if he was OP enough to inject mana into some kinda 'chewing gum'/dental hygiene to make it a cure unless healing magic is enough
