Even Though I Just Want to Be a Easy Going Adventurer! The Legendary Sword is No Match For Bronze Sword +999 in Front of Me

One day, after defeating a skeleton, Krishna, a newbie female adventurer, got a bronze sword drop. When she used her "appraisal" skill to check the sword, the sword absorbed magical power from the surroundings and became Bronze Sword +999 which was clearly much stronger than a legendary weapon. She wanted to continue being an easy going adventurer after getting the SSS-rank bronze sword, but her surroundings would not allow her. And somehow a little orphaned girl from a fallen noble who has come along with her tried to make her become a hero. Wherever they go, the two of them will create an uproar!
