What can kill people?

I looked at the history and found that it has no age, and the words "benevolence, righteousness and morality" are written on every crooked leaf. I can't sleep anyway. I read it carefully in the middle of the night before I saw the words through the gap. The book is full of "cannibalism"! There are so many words written in the book and the tenant said so many words, but he looked at me with strange eyes. I'm human too. They want to eat me!
