[In the Ninth Carriage, Jade had already moved here to eat the last Blood Fruit that would allow her to evolve into a High Human.]
[You had already told her the process of evolving into a High Human, so she knew about the impurity discharge and skin shedding.]
[Because of that, Jade wanted to do it privately and had also asked you for an Instant Clean Scroll, which you didn't refuse.]
[Instant Clean Scrolls weren't that rare, and you knew it was due to the World Will wanting players to be motivated to get items like these to improve their quality of life.]
[Since the train was already Level 9, it already had nine carriages and one locomotive.]
[Those nine carriages were identical to each other and weren't anything special.]
[You already knew from the World Will that a Train Carriage Modification Blueprint was needed to modify it.]
[You haven't opened every treasure chest yet, and they were still stored in your system inventory, so you didn't know if they had one.]
