Bab 1076: That experiment

In the library of the British royal family.

Xu Cheng saw that there were a lot of books from the Middle Ages to the modern era, including pictures, text, and paintings of the royal family. He casually picked up some books and flipped through them, and some of the books with quotes from the classics were indeed authentic.

However, because there were too many books, it was not easy for him to pick out the stories about the Duke.

While he was aimlessly flipping through the books, the door was gently pushed open and closed by William.

"Please follow me." William said to Xu Cheng as he opened up a secret room. After the mechanism inside was activated, a dark cellar that looked like an underground Castle lit up with fire. Below was a spiral staircase with hidden compartments all around with books inside.
