It seems Yan Shuang has already read all about Ling Zhenfei's Divine Immortal Water and other related materials.
This innocent child is discovering things she never knew existed for the first time.
Ling Zhenfei said, "They're just some ancient recipes that I happened to find."
Of course, Ling Zhenfei must be a little modest, even in front of a beautiful woman.
If it were someone else, this great opportunity would definitely lead them to boast about how amazing they are and how they invented the Divine Immortal Water.
Actually, using Xuantian Spirit Spring Water as a cosmetic was indeed an invention of Ling Zhenfei's.
At this moment, a notebook was handed to them from behind, and Ling Zhenfei and Yan Shuang both turned around to find it was the actress who admired Ling Zhenfei earlier, asking him to sign it.
Ling Zhenfei signed the notebook and then handed it back.
