Under the summons of the Fairy King Kaka, the fairies seeking refuge one by one returned from the Library's White Ball to the castle, now in ruins, and, following Kaka's orders, began to clean up the debris.
Apart from salvaging usable materials from the wreckage, this was also to pay Yang Yu the compensation he was due.
After seeing Li Yan off, Yang Yu naturally broached the topic of his reward.
Yang Yu indicated that rather than material rewards, he was more interested in intellectual satisfaction and brought up the White Ball that was placed in the Sky-reaching Library.
The White Ball could locate the position of books based on the prompted information, a task that could not be accomplished by mere manual effort.
Kaka readily explained the operating mechanism of the White Ball to Yang Yu without reservation.
Without the support of the fairies and the Fairy Secret Treasure, in the end, the White Ball was just an ordinary Magic Device.
