She was about to stand up when Wen Nian already came over, smiling as he asked, "What did you hide?"
Song Lili looked at him suspiciously,
"Are you a dog-eared person?"
"Uncle Wei said that as soon as you returned, you were in the study. The lights in the study were bright, but the door was closed. You sat alone at the desk, but the desktop was clean, without even a book..."
Wen Nian analyzed like a detective.
Song Lili had to admit his keen observation and logic.
She took out the drawings she had stuffed into the drawer.
Wen Nian walked over to her side, looking at the several drawings which had obviously been torn and then glued back together.
"Is this... a design for military weapons?"
"Didn't I tell you I have read a lot of books on this topic..."
"Right, these designs are..."
"Military weapons from five or six years in the future."
"..."
Wen Nian was astounded.
