Now it's Joe Tianchang's turn to be speechless. No wonder he can develop tongbaozhai to this point.

"You're really sensitive to numbers, but what do you find in so many books?" Qiao Tianchang looks at Ning Mengyao and asks.

Ning Mengyao nodded, "look at this account book first."

Qiao Tianchang took over and looked suspiciously. The more he looked at his brow, the more he frowned: "he has been losing money all the time?"

If he remembers correctly, the business in this family is still relatively good. Even if it can't be the same as tongbaozhai, it won't come to this point?

Ningmengyao slightly hook up the corner of his mouth, looking at Qiao Tianchang and saying, "you are looking in the opposite direction."

Qiao Tianchang starts from the last page.

After reading it, his eyes were full of surprise: "they use the account books to remember backwards?"

"Well, not only do you remember it backwards, many places in it are in disorder. It's like this one. This account book needs to be seen from the middle. After seeing part of it, it needs to be seen from the last page, and then it can be seen from the front." Ning Mengyao nodded and explained to Qiao Tianchang.

Qiao Tianchang looked at the account book in his hands without any words. He had just read the account book according to the way Ning Mengyao said. It was exactly the same as she said.

"How did you find out?"

"In fact, it's my memory of numbers. I don't quite understand." She felt that way after she read the books.

"But why do they do that? Won't it be very troublesome? " What do they think of the mess up of the books?

Ning Mengyao looks at Qiao Tianchang funny and takes out an account book from the side and puts it in front of Qiao Tianchang: "Tianchang, do you find anything wrong?"

Qiao Tianchang looked carefully. At the bottom left corner of zhangben, he saw a few small numbers.

"Yao Yao, I see what you mean. They have done something on the cover of the account book. When people get the account book, they are most concerned about the contents, not the surface." Qiao Tianchang said suddenly.

Ning Mengyao nodded, "you are right, and you don't find the mystery in the account book. Even if you find the mark on the cover of the account book, it's useless."

"But I don't understand."

"Don't understand what?"

"I don't know what they are doing for."

To Qiao Tianchang's question, Ning Mengyao put the paper that recorded the number in his hand.

This paper has not only recorded numbers, but also recorded a lot of Chinese characters. It's just disturbed by irregularity. I can't see what it means.

"These..."

"In fact, this is also what I found accidentally. The first word at the beginning of each page of the account book can be connected with the last word on the next page, and the last word is connected with the first word on the next page. You can see it just like this account book, you can see it in the way I said." Ning Mengyao hands the first account book to Qiao Tianchang.

Qiao Tianchang took the account book and looked through it. When he finished reading it, the whole person was surprised, because the words in one account book actually said something about that family.

"What's the matter with Yao Yao?"

"I can't give you the answer right now. I need to read all the books and arrange all the words before I can tell you the answer." Ning Mengyao smiles and shakes her head. The arrangement of these words in some account books behind her is more complicated, which is why she hasn't finished reading the account books.

Qiao Tianchang nodded: "OK, but you should also pay attention to rest. We are not in a hurry."

"Don't worry, there is Qingshuang looking at me. Even if I want to read more books for a while, I won't be able to do it." Ning Mengyao said, helplessly and funny.

Qiao Tianchang leans on ningmengyao's side and suddenly feels sleepy looking at him.
