Advising Merlin and Elizabeth

"Mm… You girls have accomplished a lot while I was away," Leonardo swept his eyes across the numerous papers, the white triangles in his eyes spinning slowly the more he read. "Energy perseverance? I see, I see…" 

It didn't take long for Leonardo to finish going through years of documents and research—his speed at all didn't surprise the two girls as he was a cultivator, unlike them who could only do things by the book. 

It should be said that their mental fortitude was indeed exceptional, or should he call it that their pursuit of knowledge was too staunch? They didn't even react to the change in Leonardo's eyes. 

Well, Elizabeth was too conservative to look Leonardo in the eyes while Merlin was, as Leonardo speculated, too bothered to even consider the changes in his person. 

Thud!
