I Was Expelled From the Hero’s Party, but Because I Can Create Legendary-Class Items, My Territory Has Become the Strongest

I was expelled from the hero party. The reason was because I was deemed useless, and not only was I expelled from the party, but I was also expelled from the adventurer’s guild. Gracius, the hero, considered me to have no value and even took away my money. I actually think that being expelled is not that bad. The reason being, I am an alchemist and can actually create legendary items that only I can make. I went to a remote territory and used the legendary item to develop the land. As a result, the territory became the strongest. Meanwhile, both the hero and guild master fell from glory and hit rock bottom. This is a story about how, if I had been working hard for the adventurer’s guild and increasing our allies instead of being expelled, we would have had the strongest territory.
