After Reincarnation, My Companions Are Toys from the Real World?

【Lord】 【Farming】 【No System】 【No Magic】 Huh? How did I end up reincarnated as a down-on-his-luck noble in another world? Why does the beast-eared maid looking after me seem so familiar? Holy crap! Isn't this the figurine I just got? It turned into a real person! Fan Xia, a modern-day STEM guy, uses the memories he brought from his past life to thrive in another world! Sure, this city is a mess, but I think a technological revolution could still sweep the place. This soap is nice, right? It's for washing, hey, don't eat it! This isn't a colored-glass cup, it's just an ordinary glass cup! A fire poker? No, no, this is a devastating weapon. Aren't you a great warrior? Come take one of my peanut bullets! What? The Demon King is that powerful? Will one nuclear bomb do the trick? How about two? Why bother looking at the tags? Your brains and your girlfriend are the strongest golden fingers there are!
