After Zhao Xu told Antonya about the entire process of how he had mastered his advanced abilities, he especially told her about how he had made a vow to the origin of magic that he would do anything for her until he died.
antonya didn't say much. she just went over to the desk and opened a "borrowing certificate" for him, asking him to find the answer on his own.
the next day, after zhao xu restored his spell slots, he took out the parchment that antonya had given him and started heading towards the destination that was recorded on it, the library of legends.
compared to the scholarly library, which could provide a wealth of knowledge for players to improve their skills, the legendary library had no such records at all.
Zhao Xu had flipped through the beginner wizard guide book. It recorded the locations of most of the buildings in the floating city, and the core area of the floating city, the "Hall of truth," was not a secret.
