Wang Haitang's words made my heart sour, as if an old man was telling me to find Xue Xiaxia.

I went back to my bedroom and lay down, rethinking the dream Wang Haitang had just described to me.

How can a piece of farmland be so similar to the environment of the fish seller in the ink painting? Could it be related to the fish freak?

When I think about it, I was scared into a cold sweat, and once I have something to do with the fish seller, it will be ...... No, absolutely not!

On the morning of the second day, I passed by the bookstore again, the bookstore had not yet opened, and I couldn't determine where Ma Yuan was, so I came out for a meeting at noon, and when I came back, I took a detour, and the door was actually open.

I was so excited that I quickly stopped and walked in.

Ma Yuan sat behind the cash register as usual, still smiling lightly, holding the purple sand teapot, as if nothing had happened before.

Regardless of whether this guy's calmness is true or not, at least he has a very good mentality.

"Mr. Zhang came to read a book?"

"You don't come to this set. It's almost time to heal these days, so it's time to be honest with me, I've already made an exchange with you. ”

Ma Yuan unhurriedly put down the purple sand teapot in his hand and asked indifferently, "Then what do you want to know?" ”

"What do I want to know, don't you know? Earlier you told me about a very important friend, and I'm going to ask you how she is, and you have to tell me the truth. ”

"Why is Mr. Zhang always so uncontrollable, giving people a feeling of impatience, this is very bad, really bad, you will suffer in the future."

This guy really looks like a Tang monk, with a lot of nonsense, if it weren't for the fact that I'm waiting to ask Xue Xiaxia's whereabouts now, I would have given him a big slap in the face.

Ma Yuan nodded slowly, and then touched his chin, "You understand the rules, I can't say it directly, but I'll give you a hint, it's enough for you to find it yourself." ”

I suppressed my anger, "Then you say, I want to listen carefully." ”

Ma Yuan folded his arms on the cash register, and said slowly, "There is the third bookcase on the left side of the entrance door on the second floor of the bookstore, and the 19th book is counted from left to right on the second floor. With that, he lowered his eyes.

I frowned slightly, silently repeated what he had just said, turned around and walked briskly up to the second floor, and found the book on the second floor of the third bookshelf as he had just said.

I almost fainted when I saw the cover of the book, it was actually an advanced math book.

Although I am a science student studying medicine, I really have a headache for me to have advanced mathematics, which is not much simpler than oracles, not to mention the content in it, I don't think it has anything to do with clues.

But since the clue he gave was this, I thought there should be a mystery hidden in it, so I took the book and went downstairs reflexively.

"Is that it?" I put the book in front of him.

He didn't shake his head or nodded, he picked up the purple sand teapot and took a sip, "I've already said everything that should be said, don't embarrass me for the rest, if you want to exchange in the future, you can come to me with the terms of the exchange." ”

Rogue rhetoric! I really wanted to pick up the book and smash him on the head a few times, but I held back.

I squeezed a phrase out between my teeth, "I hope the clues you gave me are useful."

He chuckled softly, but not with any ill intent, and I glanced at him, turned and walked briskly out of the bookstore.

I went directly to the hotel office with the book, this advanced mathematics was published in 1980, not new, the book, I don't know how many people have passed through the hands, although it is not very old, but the cover is a little hairy, the middle page is quite flat, there are some sketches and drawings in it, it can be seen that the people who used this book before are not like me, it is definitely a good study, not used as a decoration.

It took me more than two hours to read the whole book, but I really couldn't find anything suspicious in this book.

Probably because I was not interested in advanced mathematics in the first place, I lost my keen sense of smell from these numbers and the texts about mathematics.

I put down my book and went to the dining room with Zhao Heizi for dinner, and I talked to him about this advanced mathematics book during the meal.

Zhao Heizi's expression was more painful than me when he heard it, "I am probably only at the level of the second grade of junior high school in mathematics, advanced mathematics, I really ......"

He shook his head again and again, making a very resistant expression.

I couldn't help but laugh, "Big brother, please, I didn't ask you to understand what difficult math problems advanced mathematics solves, I just wanted to ask you to help me think about what is in this book that may be clues that I have ignored." ”

He thought about it seriously, pinched his chin and looked into the distance, but he looked very much like a failed high school student who had been tutoring for many years.

"It should be words, words that appear often, or words that you think are strange."

I knocked on the table helplessly, "Most of the words in it are related to mathematics, and even the ones that are barely poetic will not appear, and the others are mathematical symbols and numbers, what do you think?" ”

Zhao Heizi smiled awkwardly, "Then I don't understand this, you go back and think about it again!" ”

I wasn't in the mood to rest after eating, so I went back to the office after a few casual words with him.

I sat on the chair and suddenly remembered what Zhao Heizi said just now.

By the way, since it is a number that often appears, will it be related to the number 1140 on the note left by Xue Xiaxia?

I quickly opened the page of Advanced Mathematics and searched down from page 1, and on page 46 of the calculus operation, I actually saw the number 1140 circled by the user with a red pen.

My hands trembled with excitement, why didn't I notice the red circle before the book had been marked in a hundred places?

This 1140 is a number in the whole calculus operation, and I'm not sure if it has the same meaning as the 1140 on the note, but if you think about it, the user circled such a number individually, it should not be arbitrary.

This is the clue that Ma Yuan gave me, but what is the connection between the 1140 that appears on page 46?

I racked my brain for a long time, and remembered the previous book "The Legend of Sunrise Ida", using that book as a "dictionary", will I find some hidden clues by contacting 46 and 1140?

I was excited, and I didn't know if I was right to guess that, but at least it was better to have a clue than if I had locked myself in a dead end.

I immediately picked up my book and got up and left the office and headed straight home.

I found the book "The Legend of Hirise Ida", and turned to page 46, and I marked the Chinese characters at the back word by word, and actually found the three characters on the note. The Last King Zhou.

This is supposed to be another demonic plan, and the words I found in this book are all put together by the name of the plan.

As for what that 1104 means, I tossed until more than 1 a.m., and I couldn't find a reasonable explanation.

At least now I have preliminarily concluded that Xue Xiaxia has something to do with their organization, so I traced these three words with a brush on paper, added 1104, and rushed to the hotel with the note.

I went to the Yin Hotel with Zhao Heizi and found Xiao Ash and asked him to identify these three words plus 1104, whether this is the name of a plan.

He frowned and thought for a moment, then nodded, "It should be." ”

Although each plan in the Demon Organization has a different executor, they have communication with each other, and Ash remembers hearing the members of the organization talk about this plan before, and the name is "The Last King Zhou".

As for 1104, he said that this plan should be expanded to a radius of 1140 kilometers around a certain point, and he didn't know exactly where he was, and I needed to explore and find it little by little.

Xiao Ash said that this plan was only a relatively basic one, mainly to provide it to the entire demon organization by sucking the spiritual energy and yang energy of young children, so Xue Xiaxia was safe in their hands for now.

His analysis is also very reasonable, and it is the same as what I think, but I am still very anxious, Xue Xiaxia has been missing for a few days, I don't know what kind of torture she is suffering now, when I think of this problem, I feel painful.

On the morning of the second day, I went to the bookstore again, and I asked Ma Yuan to provide me with some more detailed clues, but he played a scoundrel, saying that what he could say had already been said, and the reminders he had given me had been given, so that I could stop in moderation.

The demon organization really chose him as the core figure, and his mentality and methods are too suitable for sitting in a high-level position.

As for the axis that Xiao Ash said, I think it should still be the axis of the bookstore, just like the previous case, the existence of the entire bookstore is also very important to the entire demon organization, so I use it to open a breakthrough.

But Zhao Heizi advised me not to start the search yet, and it is very likely that they will use other plans as a ploy to divert my attention.

And I'm also worried that something else will happen in the near future, once I leave the situation, it will get out of control, and the so-called 1140 is indeed not easy to confirm in a short period of time, after all, it is a large range, and we will collect it within the visual range for a few days.

Three days passed in a flash.

I arrived at the bar that night, asked the bartender to mix a mild cocktail, and I sat down at a table in the corner.

It was the first time I've been to a bar for a drink since it opened.

There is melodious music playing in the bar, and there are not many customers at this time, everyone is talking about their own things in a whisper, and the atmosphere is very good.

I looked sideways at the bar, thinking about my own thoughts.

I never thought that Xue Xiaxia would have such a thing, I naively thought that as long as I didn't accept her feelings, she would be safe.
