I can't figure it out.

The place where people ate people for 4 thousand years, I didn't know until today that I had been in it for many years; Eldest brother is in charge of housework, and my sister just died. He may not be in the food, but he gave it to us secretly.

I may not have accidentally stopped eating some pieces of my sister's meat, but now it's my turn. ...

With a 4000-year history of cannibalism, I didn't know at first, but now I understand that it is difficult for people to see real people!

There are still children who haven't eaten anyone.

Save the children ...
