Thanks for the chapter!
The dragon is over 300 years old and yet looks like a child in human form while Frey looks like a woman in her late teens or early twenties. Is this because of preference or a reflection of how mature they are in their true forms? Like a dog reaches maturity faster because dog years are shorter than human years, so Riza is still a child in human form because in dragon years she's still a child, right? In any case, seems like MC has found a servant to come with him. Seems odd adventurers knew there was a dragon nearby since Riza always went out to get books in human form so how'd they know to come in force? Seems like they were the typical greedy humans concerned only for potential profit and self-gain rather than consider that by attacking the dragon they could cause a disaster to anyone in the area due to retribution for being attacked, didn't even try talking just started attacking and burned a valuable collection of books due to lousy aim, and didn't consider the dragon worthy of respect or talking to as a sentient being and just potential profit.
