As we rode the carriage towards the mountains, I found it absurdly useful how we didn't need to take breaks thanks to the non-biological nature of the Golems that powered it.
Unlike horses, they didn't need food, water, or to replenish their stamina, so whenever we weren't taking a stop to sleep, we could keep going, and we didn't even need to steer or drive them at all because we were practically going in a straight line.
Of course, there were a few hiccups whenever some hostile Golems arose from the ground and attacked us, but they were sorted right away with the power of the Protagonist's harem.
During this time, I also wondered if it might have been useful to purchase something like Trap Fabrication to use on the Protagonist, and I actually did heavily consider buying some poisonous herbs to sneak into his meals, which was part of the reason why I ended up being the one offering to prepare our food, but in the end I decided against it.
