In the end, Billy left his house as soon as lunch was finished, and he confirmed that Kate and Natalie were taking their nap. Improving his cart speed might cause more problems than it solves. Still, Billy was considering doing that in order to return home sooner.
In any case, as soon as he arrived at Gustav's town, Wind of the north dungeon town, Billy headed toward the guild. He had heard about it, but the temperature of the area sure was something else. There was an inactive volcano near the town, but the place still emitted a lot of heat for some reason. That was why the area was so hot and the monsters quite troublesome since they always had that boost in attack power. That was why the Adventurers there used few clothes.
"You are…" Gustav frowned when he was about to enter the guild and saw Billy.
"It has been a while. Do you have a minute?" Billy asked.
Now that he thought about it, even if he was a dungeon master, he had to ask for permission and then mark a date to use the dungeon. He probably won't have the chance to use it that day. However, Gustav just frowned upon hearing that Billy wanted to use his dungeon. He didn't hear the details, but he knew that Billy had a method to move fast between places, so he could go as well to his dungeon town and not his.
"We are a bit shorthanded these days on the number of adventurers, so you can enter right now if you want," Gustave said. "Are you planning to do this for how long?"
"At least for a month. Thank you for your understanding," Billy said.
"It is nothing… Can I ask why you don't use your own dungeon instead?" Gustav asked.
"Sure, the monsters here are tough… Or so I have heard," Billy replied.
Gustav realized that Billy was going to enter the dungeon alone as well… Considering the things that he had heard of him recently, he probably would be fine. Still, sometimes things inside the dungeon can get messy, and just brute strength doesn't solve the problem. Regardless, Billy also asked Gustav where he could find some guys that could get the materials for him. That day, he was planning to use the dungeon just for two hours. Still, even so, since Billy already knew about the monsters and how to kill them, he imagined that he would kill more than a few dozen.
Gustav helped him with that as well, so Billy realized that he owed him quite a bit… Or maybe not, since he would help boost his earnings in the guild. In any case, since he was planning to stay on the first floor, Gustav introduced him to two helpers. They had some special knives and some of the cores of the cold golems that Billy and his friends faced years ago… He forgot. Still, most people used those to endure the temperature inside the dungeon.
"Mister… shouldn't you buy one of those?"
"It is fine for today, and just Billy is fine," Billy said.
As soon as they arrived in the dungeon, the guards opened the path since they had been informed by Gustav, and without wasting time, Billy jumped toward it.
Billy was used to hot places due to his workshop. At some points of the day, the tunnels get pretty hot as well. However, the dungeon was even hotter than that. The reason was the fact that the walls, the ground, and the ceiling… All of them were emitting constant heat.
"It is almost like the interior of a living creature…" Billy thought. "Despite that, the heat doesn't leave because it is absorbed by the monsters."
Speaking of monsters, they showed even faster than the helpers could enter the dungeon. The monsters of the first floor were two red spheres that almost looked like balloons, but those even had teeth, and his eyes emitted a yellow glow as if they were smiling at something. It was quite creepy… In any case, Billy pointed his hands at them before they could open their mouths, and they became ice statues that fell and shattered.
The skill Water Manipulation received 200 experience points.
The skill Water Transformation received 200 experience points.
Billy defeated those monsters almost instantly, but he wasn't satisfied with that. From his perspective, Sarah was way better while turning the surrounding air into water and then into ice. Still, he has room for improvement, and it seemed that things would improve rather fast inside the dungeon while receiving that amount of experience. Regardless, the helpers finally appeared and then frowned upon seeing the corpses of the fire spirits. They had heard of weapons that could freeze them, but only famous and rich Adventurers had them.
Moreover, Billy didn't have a single weapon with them. He left them at home since he didn't want to let them melt in that place. Even if he doesn't block the enemies' attacks with his spears, attacking them so many times would make them lose durability.
In any case, the helpers began to look for the materials inside the blocks of ice that the bodies had turned into. Although Billy froze their whole bodies, they still found red marbles inside the monsters. Billy recognized those… They were the items that Valentin used on the chimney of his house. Just by putting that there alongside some wood, it was enough to warm the entire living room.
