Nightwatcher

Afterwards, they found many books that could be found everywhere to decrypt the code in this way, but they all failed.

Song Tingfeng and Zhu Guangxiao were a little discouraged. The former narrowed his eyes 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 sharp as before.

Xu Qi'an raised his head, stared blankly at the criss-crossing beams, and said angrily, "Did your friend feel particularly lethargic during the few days when he was in poor health?"

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

"Hehe." Xu Qi said with peace of mind, I haven't slept in thirteen days, how fast do you expect my brain to turn? Susu's useless thing can't even refresh her mind, so what's the use of raising her.

However, the advantage of this charm lies not in the core, but in the supporting shell.

Raising a Mei is equivalent to raising a fish pond, which is more relaxing and comfortable than raising Huaiqing, Lin'an, Fuxiang, Caiwei and other spare tires.

When the time comes, the fishpond owner Xu Qi'an holds a steel fork in his hand, and will quickly and ruthlessly insert any fish he likes.

"It's better to take a break." Song Tingfeng suggested.

"Let the postman bring some sweets over." Xu Qi'an said.

The best way to fight against 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 that the sweets are delicious, but the brain prompts the body to consume sugar.

Xu Qi'an needs sugar very much right now.

The postman made them sweet longan egg flower soup, raisin pastry, and sweet almond tofu.

Xu Qi'an was short and pulled out the general, chose the sweet longan egg flower soup, and pushed the almond tofu nao to his squinted eyes. Song Tingfeng suddenly became happy, and said with a smile: "Ning Yan, how do you know that I like sweet tofu nao."

Because you look like a heretic Xu Qi'an smiled and said: "Because we are brothers, seeing you wash your face with tears, I will give you tofu brain to sweeten your heart."

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

Having said that, girl Susu is really wonderful, it is rare, Song Tingfeng, the girl who can fight with me for 300 rounds, thinks about the ecstasy that happened in the private room of the teahouse today, ten o'clock.

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

"In the past, when you first joined the watchmen, I advised you to marry Lu Qing and Lu Butou, but you shyly disagreed, so you turned around and fell in love with Fuxiang. I knew you were of the same kind at the time. If Lu Butou married Here you are, a flower stuck in cow dung."

Lu Qingying's valiant appearance flashed in Xu Qi'an's mind, and he said angrily: "Although Lu Tuotou is not as beautiful as Fuxiang, you call her cow dung, that's too much."

"I didn't say she was cow dung, I said you."

"Then what do you mean by flowers stuck in cow dung?"

""

After eating dessert, because the famous detective Xu Ningyan was not in good condition, Song Tingfeng took the initiative to assume the burden of reasoning and cleared his throat:

"Let's think about it differently. If I were Zhou Min, I would definitely hide the password book in a place where the governor's team can find it at any time, but it will not attract people's attention."

"En!" Xu Qi'an nodded.

"Zhou Min's residence has been checked, and there are no hidden compartments or suspicious things. We have also compared the books he left behind just now." Zhu Guangxiao said.

Song Tingfeng thought for a while, and rubbed his chin, "Maybe, maybe it's not a book? Zhou Min is thoughtful, and he can think of things that others can think of.

"Let's think about it differently. It might be something with writing on it, but it's not a book? Ning Yan, do you think it's possible?"

"Very good, Ting Feng, your ingenuity has successfully caught my attention. You are a genius who was delayed by the woman of the Jiaofang Division." Xu Qi'an praised her and asked:

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

Xu Qi'an suddenly stopped.

"Is it Huang Li?!" Song Tingfeng shouted out first.

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

"That's it!" Xu Qi'an exhaled the turbid air in his chest, his eyes brimming with excitement.

It is both a book and not a book. Both eye-catching and unremarkable. According to the speculation and analysis of Zhou Min during this period of time, Xu Qi'an can confirm with great confidence that this is Zhou Min's style.

The three couldn't wait to open the almanac, starting from the first character, counting to the 162th character according to the figure: day!

The "day" of Yimao Day.

Then came the three hundred and forty-seventh word, the fourth word, the first word, and the second word.

Put it together: Mo Riguang Ding Yiwu!

Obviously, this is wrong.

Then, they use the second method, taking page counts instead of word counts.

If the number of pages is taken, then each number of words corresponds to a certain day in the calendar. The combination is as follows:

Momo, April 6th, January 15th, January 29th, January 25th, January 26th.

"Day, it's wrong again." Xu Qi'an threw away the calendar, scolded his mother, "This way of thinking is wrong, start over."

"Maybe we can unravel the word "mo" first, because it is the only word and it is at the top." Zhu Guangxiao put forward his own ideas.

The meaning of the lead is very important.

Xu Qi'an squeezed the space between 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, does it?"

Song Tingfeng pondered and said: "The governor and Jiang Jinluo have already studied the code. If the word "mo" points to a code in the yamen, Jiang and the governor should be able to find out."

"What can the governor find out? He is also good at guessing charades." Xu Qi'an curled his lips, and the next moment, he was stunned.

An aura burst out in his exhausted mind, flashing like lightning.

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

When analyzing and profiling the target person, first of all, we should collect as much information as possible about the target person and understand their habits.

No matter how cunning a criminal is, his behavior pattern can be traced, that is his habit.

What are Zhou Min's habits?

It's an anagram!

Yang Yingying said that Zhou Min likes to play crossword puzzles with her while drinking. Therefore, when Zhou Min is thinking about how to hide evidence and leave clues, he will habitually move closer to crossword puzzles. From this, it can be inferred that among the two sets of codes, the only A word is also an anagram. Xu Qi'an's thoughts became clearer and clearer.

Song Tingfeng and Zhu Guangxiao looked at each other, and kept silent tacitly. Just a moment ago, Xu Ningyan's state returned, just as wise and focused as when he was investigating the Sangbo case.

Mo Mo, it's a black dog when it's taken apart Xu Qi'an pinched his brows and asked, "I remember my colleague who went to Huang Bo Street said that there is a dog market there?"

Song Tingfeng said "hmm": "It's a dog market, what's wrong?"

Xu Qi'an said: "Separate the silent characters, they are "black" and "dog", and the information on Huangbo Street is the clue left by Zhou Min in the last word puzzle game. I think it can be matched now."

"Do you think the code points to the dog market?" Song Tingfeng frowned, "Then what does the black represent? Is it too arbitrary to judge that the code points to the dog market with just the word dog?"

"I have an idea." Xu Qi'an didn't finish speaking, and went out to call the postman.

"My lords, what are your orders?" said the postman.

"How much do you know about Huang Bo Street?" Xu Qi'an asked.

"Huangbo Street, that place is in chaos. It's okay during the day, and it's quiet. But at night, there are fish and dragons mixed in there. There are all kinds of people, sneakers, tourists from the rivers and lakes, and even bandits from outside. Go to that street." The postman replied.

Is the dog meat sold there, or what kind of meat is it?

"Of course not. On the surface, Huang Bo Street sells dog meat, but it is actually a black market. It sells shady things and makes shady deals," said the postman.

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

The postman suddenly showed shame, and murmured: "I went to buy dog ​​meat."

Why buy dog ​​meat with an embarrassing expression of pretending to be discovered? Xu Qi'an frowned and said, "Speak human."

The postman whispered: "I found a private prostitute at Xin No. 6 shop, and that's what I mean by buying dog meat."

Too young, even looking for a private prostitute so coyly, I dare not say that the three of them shook their heads and sighed at the same time.

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

"The black market shop is named after the heavenly stems and earthly branches." The young postman blushed, feeling that he had been publicly executed.

Xu Qi'an nodded: "Understood, you go down first."

After the postman closed the door and left, Xu Qi'an shrugged when he heard the footsteps gradually disappearing: "The situation is very obvious, the black dog refers to this black market for dog meat."

As for why there is such a place in Baidi City, it is not surprising that it is doing shady deals under the eyes of the government.

Even in the world's best city, there are many black markets.

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

"Then what do the other codes refer to?" Song Tingfeng asked himself and answered, "It should tell us who to contact when going to the black market, or how to find them."

"The answer lies in the almanac." Xu Qi'an spoke with certainty.

"We have already checked it just now." Zhu Guangxiao looked at him.

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

"It's the almanac of previous years, not this year."

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

"Guangxiao, today you are obviously not as smart as Tingfeng. There were so many in previous years, and the country has been established for six hundred years. If you want to find the correct almanac, you will undoubtedly find a needle in a haystack. Zhou Min does not seem so stupid. Since it is not this year's almanac, I guess That almanac had some unusual significance to him.

"Of course the almanac doesn't have any special meaning, but the year does, such as the date of birth, wedding day, etc. If you guessed right, it should be the almanac from fourteen years ago.

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

Fourteen years ago, the old Huangli, this time the inn is gone, only the yamen and the bookstore are reserved. In order to keep a low profile, Song Tingfeng did not go to the yamen, but went to the bookstore.

After a cup of tea, he rode a horse and returned with the old Huang Li.

Xu Qi'an found a pen and paper and spread it out on the table, thinking that his own handwriting would not be elegant, so he pushed Zhu Guangxiao out to serve as a knife and pen official.

They used the previous method, using the "number of characters" method to decrypt, and found that it was still wrong, and the copied characters were wrong.

Then use the "number of pages method", the one hundred and sixty-second page is May 12th, suitable for: opening of the market, wedding, house entry, and travel.

Inauspicious: Praying for blessings, opening warehouses, digging wells.

"Open the market!" Xu Qi'an captured the key information, "We should go to the black market after the market opens at night."

His statement was recognized by Song Tingfeng.

Then came the second set of codes: three hundred four hundred seventy four one two

Xu Qi'an turned to page 347, which was dated January 15th. He glanced at the almanac of that day, and finally realized it. Suddenly, he 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. Look at Ting Feng, the 4th, 1st, and 2nd words on this page are connected together. What is it?"

Song Tingfeng narrowed his eyes and read: "Ding 15"

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

Mystery finally solved

Xu Qi'an and Song Tingfeng felt relieved, leaned back on their chairs, and let out a long breath.

Zhu Guangxiao also put down his pen, feeling relaxed.

Xu Qi'an walked to the table, took a closer look, and said with a surprised expression: "Guang Xiao, your handwriting is so ugly."

Song Tingfeng ran over to join in the fun, and yelled, "I can't get in my eyes, I can't get in my eyes"

Zhu Guangxiao was not convinced: "Your handwriting is beautiful?"

Song Tingfeng said proudly: "My calligraphy is no worse than that of scholars. When I was a child, in order to practice calligraphy, I saved money on paper and ink."

Xu Qi'an said: "When I was young, my family was poor. In order to practice calligraphy, I used a brush dipped in water to practice calligraphy in the yard. It took me 20 years to practice."

Zhu Guangxiao glanced at them suspiciously, and handed over the pen: "Then let me see how many you write."

Xu Qi'an and Song Tingfeng turned around tacitly, hooking their shoulders together:

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

"I think so."

Looking at the back of the two leaving, Zhu Guangxiao opened his mouth, looked down at his calligraphy, and secretly decided that he would start to practice calligraphy hard in the future, and he could not lag behind them in this small team.

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

Maybe it was because his brain was too tired, he hadn't entered the state for a long time, his thoughts diverged uncontrollably, and it was difficult to stop.

Counting the time, Huaiqing and Lin'an are about to receive my letter. I hope that letter can turn Huaiqing's anger into joy, although I don't know where I offended her. Framed That silly girl must be very touched, she She's more flirtatious than Chu Caiwei's unrepentant foodie

As for whether the two princesses would exchange letters in private, or be seen by people other than them, Xu Qi'an thought it was impossible.

First, the relationship between Huaiqing and Lin'an was not friendly, and there was absolutely no possibility of exchanging letters. Moreover, the letter he wrote was a bit ambiguous. It is impossible for girls of this age to tell others about this kind of letter.

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

There is almost no possibility of his little gong writing ambiguous letters to the two princesses.

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