I obtained a secondhand trading community that connects to another world. And the reactions are absolutely incredible. [Wasn't glass originally weak to heat? How could glass with this kind of heat resistance...?] That's the reaction to a triangular flask I got from an elementary school science lab. [I-I'll buy it! Sell it to me!! What do you want!?] Naturally, I have no idea about the price. "Just give me whatever you think is fair." [I will! Speaking of this item, it has a bit of dragon heart mixed in...!] Oh, this is insane profit.
