Subsequently, they found many more books that could be found everywhere to decipher the code in this way, but all failed.

Song Tingfeng and Zhu Guangxiao were a little discouraged, the former narrowed his eyes into a slit and said, "Ning Yan, you are suddenly not smart." ”

It can be clearly felt that Xu Qi'an's thinking activity has seriously declined, and he is not as keen as before.

Xu Qi'an raised his head, looked at the criss-crossing beams in a daze, and said angrily: "Your friend was not in good health for a few days, was he also particularly unenergetic?"

"Why, why did you mention my friend's matter again..."Song Tingfeng was a little embarrassed.

"Huh. "Xu Qi'an said, I haven't slept for thirteen days, how fast do you expect my brain to spin? Su Su's useless thing, I can't do it to refresh my mind, what's the use of raising her.

However, the advantage of this charm is not in the core, but in the matching shell.

Raising a charm is equivalent to raising a fish pond, which is easier and more comfortable than his hard work to raise spare tires such as Huaiqing, Lin'an, Fuxiang, and Caiwei.

When the time comes, Xu Qi'an, the owner of the fish pond, holds a steel fork in his hand, and if he sees any fish, he will quickly insert it ruthlessly.

"Why don't you take a break? Song Tingfeng proposed.

"Ask the postman to bring some sweets. Xu Qi'an said.

The best way to combat brain fatigue is to consume sugar, sugar is the only energy that the brain can use, most people like to eat sweets, in fact, it is not how delicious sweets are, but the brain prompts the body to consume sugar.

Xu Qi'an is in need of sugar right now.

The postman made them longan egg drop sweet soup, raisin pastry, almond tofu brain.... Sweet.

Xu Qi'an pulled out the general in a short state, chose the sweet soup of longan egg flower, and pushed the almond tofu brain to squint, Song Tingfeng suddenly became happy, and said with a smile: "Ning Yan, how do you know that I like to eat sweet tofu brain." ”

Because you look like a heretic... Xu Qi'an smiled: "Because we are brothers, see you wash your face with tears, give you tofu brain, sweet your heart." ”

Who washed his face with tears? Song Tingfeng rolled his eyes, knowing that he was alluding to Miss Su Su.

Then again, Miss Susu is wonderful, it's rare to be able to fight with me for 300 rounds.... Song Tingfeng thought about the ecstasy rhyme that happened in the private room of the teahouse today, and it was ten watches.

"You won't understand, you're a prodigal son, I'm not. Song Tingfeng shook his head and sneered:

"In the past, when you first joined the watchman, I persuaded you to marry Lu Qing and Lu Zhutou, you twisted and pinched your disagreement, and turned your head to be better with Fuxiang, I knew at that time that you were the same kind. If Lu Zhutou marries you, it will be a flower stuck in cow dung. ”

Xu Qi'an's mind flashed Lu Qing's heroic appearance, and he said angrily: "Although Lu Zhutou is not as beautiful as the floating fragrance, you say that she is cow dung, it's too much." ”

"I didn't say she's cow dung, I'm talking about you. ”

"Then what did you say that flowers are stuck in cow dung?"

“....”

After eating dessert, because Detective Xu Ningyan was not in a good state, Song Tingfeng took the initiative to take on the heavy responsibility of reasoning and cleared his throat:

"Let's think about it from another perspective, if I were Zhou Min, I would definitely hide the code book in a place where the governor's team could find it at any time, but it would not attract attention. ”

"Hmm!" Xu Qi'an nodded.

"Zhou Min's residence has been checked, and there are no dark and suspicious things. The books he left behind, we have just compared. Zhu Guangxiao said.

Song Tingfeng thought for a moment and touched his chin, "... Zhou Min is thoughtful, and he can definitely think of things that others can think of.

"Let's think about it differently, it may be a book with words, but not a book? Ning Yan, do you think this is possible. ”

"Very good, Tingfeng, your ingenuity has successfully caught my attention, you are a genius who has been delayed by the woman of the Sect Division. Xu Qi'an praised a sentence and asked:

"Then what do you think it will be? It's not a book, it's in Zhou Min's relics. And it has to be quite thick...."

Xu Qi'an suddenly paused.

"It's Huang Li?!" Song Tingfeng was the first to shout.

Zhu Guangxiao, an honest man who worked hard, accurately found a thick yellow calendar in the relics: "Is it it?"

"That's it!" Xu Qi'an spit out the turbid breath in his chest, his eyes full of excitement.

It's both a book and it's not a book. It's both striking and unremarkable. According to the speculation and analysis of Zhou Min's character during this time, Xu Qi'an has great confidence and confirms that this is Zhou Min's style.

The three of them couldn't wait to open the yellow calendar, starting from the first word, and counted to the one hundred and sixty-second word according to the figure Suoji: day!

The "day" of the second day.

Then there are the three hundred and forty-seven words, the fourth word, the first word, the second word.

Combined: Silent Riguang Ding Yiwu!

Obviously, this is wrong.

Next, they used the second method, which was to take the number of pages, not the number of words.

If you take the number of pages, then each word count corresponds to a certain day in the calendar. The combinations are as follows:

Silence, April 6, January 15, January 29, January 25, January 26.

"Day, it's wrong again. Xu Qi'an threw away the yellow calendar and scolded his mother: "This idea is wrong, start again." ”

Perhaps we can unravel the word "silent" first, because it is the only word, and it is the first word. Zhu Guangxiao put forward his own ideas.

The significance of the head of the row is important.

Xu Qi'an pinched his eyebrows: "Then do you have any ideas?"

Zhu Guangxiao shook his head.

Xu Qi'an asked again: "The word Mo has no special meaning in our yamen, right?"

Song Tingfeng muttered: "Lord Governor and Jiang Jinluo have already studied the code, if the word "Mo" points to a certain code in the yamen, Lord Jiang and Lord Governor should be able to find out. ”

"What can the Governor find? Xu Qi'an pursed his lips, and the next moment, he was stunned.

Spiritual light burst out in the exhausted mind, and lightning flashed like a flint.

He remembered that when he was still at the police academy, a professor who studied criminal psychology once said that a person's behavior is closely related to his habits.

When dissecting and profiling the target person, we should first collect as much information as possible about the other party and understand the habits of the other party.

No matter how cunning a criminal is, there are traces of his behavior pattern, and that is his habit.

What are Zhou Min's habits?

It's an anagram!

Yang Yingying said that Zhou Min likes to play charades with her while drinking.... Therefore, when Zhou Min is thinking about how to hide evidence and leave clues, he will habitually move closer to the anagram.... It can be inferred from this that the only word in the two sets of ciphers is also an anagram. Xu Qi'an's thinking is getting clearer and clearer.

Song Tingfeng and Zhu Guangxiao glanced at each other, and remained silent tacitly, just a moment ago, Xu Ningyan's state returned, just like the wisdom and focus when he was tracking down the Sangbo case.

Silent, take it apart and it's black and dog.... Xu Qi'an pinched his eyebrows and asked, "I remember that my colleague who went to Huangbo Street said that it was a dog market?"

Song Tingfeng said "um": "It's the dog market, what's wrong?"

Xu Qi'an said: "The silent characters are taken apart, they are "black" and "dog", and the information of Huangbo Street is the clue left by Zhou Min in the last word puzzle game, I think it can be corresponded to now." ”

"Do you think the code points to the dog market?" Song Tingfeng frowned, "Then what does this black represent? Just one dog character, judging the code points to the dog market, is it too arbitrary." ”

"I have an idea. Xu Qi'an didn't finish speaking, and went out and called the post guard.

"My lords, what do you command?" said the postman.

"What do you know about Wong Bo Street. Xu Qi'an asked.

"Huangbo Street, that place is chaotic, it's okay during the day, it's quiet. But at night, there is a mixture of fish and dragons, everyone there, stealing chickens and dogs, tourists from the rivers and lakes, and even mountain bandits from outside will go to that street. The postman replied.

Is it dog meat or what kind of meat is it sold there.... Xu Qi'an sneered, and thought: "Mountain bandits and Jianghu guests, shouldn't they run there just to eat a bite of dog meat?"

"Of course not, Huangbo Street sells dog meat on the surface, but it is actually a black market. What is sold is something that is not visible, and it is a transaction that is not visible. "The postman said.

"Have you ever been to the black market?" asked Xu Qi'an.

The postman suddenly showed a look of shame and snorted, "I went to buy dog meat." ”

Why do you have to make an embarrassing expression of pretending to be found with your hands when you buy dog meat... Xu Qi'an frowned and said, "Talking about people." ”

The postman whispered: "I found a prostitute in Xin No. 6 shop, and this is what I mean when I buy dog meat." ”

I'm too young to find an adulteress to be so twisted and pinched to say it... The three shook their heads and sighed at the same time.

"Xin No. 6?" Xu Qi'an asked.

"The black market shop is named after the sexagenary branch. The young postman was red-faced, and he felt that he had been executed publicly.

Xu Qi'an bowed: "Got it, you go down first." ”

Waiting for the post guard to close the door and leave, listening to the footsteps gradually moving away, Xu Qi'an shrugged: "The situation is already very obvious, black dog, referring to this black market with dog meat." ”

As for why there is such a place in White Emperor City, it is not surprising to make shady transactions under the nose of the government.

Even in the world's most benevolent city, there is a lot of black market.

Huangbo Street is not far from the post station, but it belongs to the outer city, and there is no curfew at night.

"What do the other codes refer to?" Song Tingfeng asked himself: "It should be to tell us who to look for when we go to the black market, or how to find it." ”

The answer lies in the yellow calendar. Xu Qi'an said in a very affirmative tone.

"We've already tested it. Zhu Guangxiao looked at him.

"Huang Li's idea is right, but how could Zhou Min leave a crucial clue in the relic. Xu Qi'an said:

"It's the yellow calendar of previous years, not this year. ”

"What year is it?" said Zhu Guangxiao in a deep voice.

"Guangxiao, today you are obviously not as witty as Tingfeng. There were so many in previous years, and Dafeng was founded for six hundred years, and it is undoubtedly a needle in a haystack to find the correct yellow calendar, and Zhou Min does not seem so stupid. Since it wasn't this year's calendar, I guess it had some unusual meaning to him.

"Of course, the yellow calendar will not have any special significance, but there are years, such as the date of birth, the wedding day, etc. If I'm not mistaken, it should have been the Yellow Calendar 14 years ago.

Because that was the beginning of Zhou Min's appointment to Yunzhou. ”

Fourteen years ago, the old yellow calendar, this time the post station is gone, only the yamen and the bookstore still have reservations, in order to keep a low profile, Song Tingfeng did not look for the yamen, but went to the bookstore.

After a cup of tea, he rode his horse and returned with the old yellow calendar.

Xu Qi'an found a pen and paper and spread it out on the table, thinking that his words were difficult to get into the elegant hall, so he pushed Zhu Guangxiao out to act as a knife and pen officer.

They used the previous method to decrypt the "first few words", and found that it was still wrong, and the copied words were not in the horse's mouth.

Then the "page count method" is adopted, and the 162nd page is May 12, which is appropriate: opening the market, getting married, entering the house, and traveling.

Don't: pray for blessings, open positions, dig wells.

"Open the market!" Xu Qi'an captured the key information, "It should be that we go to the black market after the market opens at night." ”

His statement was agreed by Song Tingfeng.

Then there is the second set of codes: Three Hundred Wanton Pick Up Seven Wanton One Two

Xu Qi'an turned to page 347, the date of this page is January 15th, he glanced at the yellow calendar of that day, and finally suddenly realized, his mouth suddenly opened, and said:

"I see!

One hundred and sixty-two and three hundred and forty-seven refer to the number of pages, and four, one, and two refer to the number of words. Tingfeng, you see, what are the 4th, 1st, and 2nd words on this page?"

Song Tingfeng squinted his eyes and read, "Ding 15..."

Thinking of the information that the post guard said just now, he blurted out: "Black market shop, Ding No. 15?"

The puzzle is finally solved...

Xu Qi'an and Song Tingfeng were relieved, leaned back in the chair, and let out a long breath.

Zhu Guangxiao also put down his pen and felt relaxed.

Xu Qi'an walked to the table, looked at it, and said with a surprised expression: "Guangxiao, the words you write are so ugly." ”

Song Tingfeng ran over to join in the fun, and shouted: "I can't get into my eyes, I can't get into my eyes..."

Zhu Guangxiao was not convinced: "Your handwriting is very good?"

Song Tingfeng said arrogantly: "My calligraphy is no worse than that of a reader, when I was a child, in order to practice calligraphy, I saved money to buy paper and ink." ”

Xu Qi'an said: "When I was a child, my family was poor, and in order to practice calligraphy, I used a brush dipped in water to practice calligraphy in the yard, and I practiced it for 20 years. ”

Zhu Guangxiao glanced at them suspiciously, and handed over the pen: "Then you write a few for me to see." ”

Xu Qi'an and Song Tingfeng turned around tacitly and hooked their shoulders:

"Let's go, go back to the room to rest, calligraphy is not for showmanship. ”

"I think so too. ”

Looking at the back of the two leaving, Zhu Guangxiao opened his mouth, looked down at his calligraphy, and secretly decided that he would also start practicing calligraphy in the future, and he couldn't lag behind them in this small team.

Back in his room, Xu Qi'an took off his shoes and went to bed to meditate to make sure that he was in good shape when he went to the black market at night.

Maybe his brain was too tired, he hadn't been in a state for a long time, and his thoughts were uncontrollably divergent, and it was difficult to restrain them.

.... Calculate the time, Huaiqing and Lin'an are about to receive my letter.... I hope that letter will turn Huaiqing's anger into joy, even though I don't know where I offended her.... Framing that stupid girl must be very moved, she is better flirting than Chu Caiwei's unopened foodie....

As for whether the two princesses will exchange letters in private, or be seen by people outside of them, Xu Qi'an thinks it is impossible.

First, the relationship between Huaiqing and Lin'an is not harmonious, and there is absolutely no possibility of exchanging letters. Moreover, the letter he wrote was somewhat ambiguous, and it was impossible for a girl in this era to tell others about this kind of letter.

Second, Huaiqing and Framing are both mature princesses, mature enough to conceive, and have the freedom and power to send and receive letters, the emperor and concubines will not ask, and others dare not open the princess's letters privately.

The fact that he wrote ambiguous letters to the two princesses with this little gong has almost no possibility of being exposed.

Gradually, Xu Qi'an entered a state of visualization.
