Shen Youran was very puzzled by Sun Yixie's actions.
Everyone knows that martial arts manuals, especially internal cultivation methods, are not to be shown lightly.
It's not like studying in school, where you can show someone a word you don't recognize or a poem you don't understand to ask for help...
If one must make a comparison... a martial arts manual is like a high-tech weapon design diagram. Even with close friends, one cannot easily share it, let alone show it to outsiders.
"No way?" At that moment, Shen Youran also had doubts, "Could this kid really consider me as one of his own?" He was not so naive, so he quickly dismissed the idea, "No...no, he might be testing me to see my reaction; maybe the paper doesn't even contain internal cultivation methods, but is filled with nonsense...or perhaps the method described is very common, belonging to the lowest tier of martial arts, and showing it to me would do no harm."
