"Fairy Xiao, thank you."
Zheng Fa handed the few books in his hands to Xiao Yuying.
The books were about popular science of electromagnetism, well, children's popular science.
He had carefully selected these.
It wasn't that Zheng Fa was being stingy; having interacted with Xiao Yuying for so long, he had a deep understanding of her level of knowledge...
These books, perhaps...
Xiao Yuying excitedly flipped through the books, her brows lightly furrowing as she muttered, "This secret technique is indeed profound..."
Indeed!
"Fairy Xiao, you are welcome to visit the Jiushan Realm again in the future."
During this time, Zheng Fa was busy teaching Zhang, and he really didn't have time to copy books for Xiao Yuying.
This person didn't rush him either, which made Zheng Fa a bit grateful.
"Do you really not plan to leave the Jiushan Realm?"
Xiao Yuying asked in surprise.
"Uh-huh."
