Qiao Tong looked at the row of bookshelves and said, "It seems like it was right around there when the presence suddenly disappeared."
Chen Mo got up and went to the bookshelf, his eyes shimmering with purple and gold light.
But even after observing carefully with his Golden Eyes of Truth for a long time, he didn't find anything unusual.
He casually pulled out a few books, discovering that every book showed traces of being read, and even the level of dust was quite similar.
There are hundreds of books here, mostly miscellaneous notes and historical books, and he didn't believe Chu Heng was that studious; it was clearly hiding something.
"The presence suddenly disappeared, and there was no Primordial Qi fluctuation; it could likely be Mechanical Techniques..."
"Thus, the crucial point might not be the content of the books, but the material and arrangement?"
Chen Mo pondered slightly, his fingertips emitting a wisp of flame that spread across the bookshelf.
