Sherman didn't leave in a hurry. He asked the butler to find some people to take down all the books with black covers in the study and piled them aside.
If he hadn't been injured in an accident. Sherman would have done it himself.
There were only over three hundred books in black cover here, which looked quite spectacular when piled up together.
"Sir, all the books with black covers are here."
The butler didn't show any curiosity and reported to Sherman without looking sideways.
Sherman nodded slightly, "Bring me a pot of tea."
He hoped that there were books he needed, or he could only give up.
The butler left quietly. Sherman picked up a book from above and opened it.
No, neither.
He only needed to turn two pages to confirm the content and then put it aside.
The system didn't respond at all like the dead.
The treasure left by Hurd Hassey.
The history book, a map of five hundred years ago, with a painting.
