Seeing Sun Wukong's surprise, Ao Guang chuckled, "The Great Saint also feels it, this Luminous Pearl quietens the mind and concentrates the spirit, it's a supreme treasure for cultivation, perfectly suitable for the Great Saint's first attendance at the Peach Banquet."
"Could there be some kind of expectations to attend the Peach Banquet?" Sun Wukong asked in confusion.
As far as he knew, even though Lu Dongbin and the others also gave gifts, they were just ordinary items, nothing too precious, at least not comparable to this Luminous Pearl.
Ao Guang nodded, laughing as he said, "Usually, those attending the Peach Banquet for the first time will present precious gifts to show respect towards the Queen Mother of the West; the next time they attend, they can give more ordinary gifts. After all, even Immortals can't have an endless supply of treasures."
So that's how it is, Sun Wukong understood.
