"A kind of entertainment toy,"
Sun Wukong thought for a moment, then added, "It can also be used as a weapon."
Haruno Sakura looked at the black and white Youyou ball in her hand and continued to ask, "How should it be used, then?"
"Perhaps you could connect the center axis with Chakra threads and then swing it out," Sun Wukong suggested. "This isn't a true Youyou ball, it's a kind of recording device that can display memories of Chakra."
After pondering for a moment, Haruno Sakura concentrated her Chakra into threads. Following Sun Wukong's suggestion, she swung the Youyou ball out, and the black and white "Youyou ball" spun at the end of the Chakra thread, forming a 3D holographic image of a father and daughter.
The child was none other than Little Snow from the Land of Snow during her younger years, and the middle-aged man was her father, Hanxue.
The father and daughter were talking.
The father asked his daughter what her dream was.
