He rants about how he accidentally destroyed the original copy of the book, and how he's already written a new one. He says that zhu locked him up and forced him to rewrite the book every day, and that if he didn't complete a certain amount she wouldn't give him food. He finally gets his phone back and calls zhu for help. He tells zhu that he is the same as zhu and that he has the missing pages from the book. They agree to work together to solve the mystery of the missing book. .
