I meant Lord Balebrook words about 'brought some inventions' did not mean physical items from the world you departed from but rather brought old world ideas and inventions and build them in this world. Example concept for trains. Or rules for American football and it turning into the national sport in one Free Nations or someone opening a fast-food restaurant as I did refer before (Queen's Burgers vs McGold).<br/><br/>So no, no physical items from isekaid folks. Even having a dead cellphone (no signal nor able to make calls) can be dangerous to have as an item. Ofc you can try create cellphones (but need work with what this world has to offer).
