Chapter 544: Chapter 544: Bearing Humiliation and Burden, Being a Cat Again

Upon hearing this, Rui'er immediately took the book and checked it carefully, frowning, "I have read this book a few times, but I didn't find anything unusual. However, it is indeed a bit heavy."

She flipped through the pages with a rustling sound, muttering to herself, "Why is it so heavy?"

Jiang Ning brought the lantern closer, making the pages translucent.

That's when they discovered the clue.

It turned out that each page consisted of two layers, with what seemed to be another layer sandwiched between them.

Jiang Ning turned and asked, "Gucheng, do you have a knife?"

Gucheng immediately handed her a small dagger.

"Miss, let this servant do it, don't cut your hand." Rui'er took the knife and carefully cut open a page, revealing the hidden layer in the middle, which could be pulled out.

She took a look, and it was a letter.

"Miss, look at this." She hurriedly handed it to Jiang Ning.

Jiang Ning quickly scanned it: "It's a letter written by that man to her."
