The world has turned into a hell, a place where the strong thrive!

Weary reader, it is an honor for you to choose this book in this heavy, dark library room.

Somewhat sadly, the book is sick.

Your fingers should be able to feel the raised growths on the surface of the book cover,

The words written in the old days are like parasites rooted in the pages of the book, hoping that someone can observe their wriggling,

To feel, to analyze, to touch the story of the disease.

If you insist on borrowing this book, be sure to check your physical condition regularly.
