"Where did this notebook come from?"
Andy's eyes revealed a trace of shock as he turned to ask everyone.
"It's one of my students. More accurately, it should be a prospective freshman."
"His name is Ye Feng."
Professor Lei stood out with an expectant expression on his face.
"Ye Feng? That's right. This notebook is real, but the strange thing is that the last secret text, the Sequence 13 secret text, has disappeared."
"But what we can be sure of is that the contents of the other notebook are indeed authentic."
"If I didn't see it with my own eyes, I wouldn't even believe that this long-lost secret manual could actually return to the world."
As Andy spoke, he waved his right hand, and six copies of the secret manual were instantly duplicated.
"This secret manual belongs to the common property of humanity."
