Start with detective Li Yuanfang

Chapter 42 Free is always the most expensive
"Pei Dudu is here, and you are a yamen messenger, why don't you dare to speak?"

Kang Meng thought that Shi Jing was talking nonsense, and hurriedly urged: "No matter which noble family it is, just say it!"

Shi Jing thought about it for a while but still didn't dare to take the risk: "This case is of great importance and involves Shangguan. I'm a humble person, so I can't talk nonsense."

Kang Meng was stunned: "Shangguan? Your Shangguan is me, Aye. When did I have a servant like Lu San in my family?"

Shi Jing hesitated to speak, and said in a low voice: "A little more..."

Kang Meng froze for a moment, and after a while, he squeezed out three words: "Magistrate Cui?"

Zhang Huanhe's expression changed drastically, and Lin Yuzuo, who had been standing aside, lowered his head immediately in fright.

In the Tang and Song Dynasties, officials of the seventh rank could sit in one side, and Cui County Magistrate, the county magistrate of Guzang County, was already in charge of administrative and civil affairs of one side from the sixth rank.

Checked, checked, found him?

Kang Meng was white, but his father Kang County Wei Ke served under Cui County Magistrate, so he immediately looked to the bigger leader Pei Sijian as if asking for help.

Pei Sijian looked calm, took the account book and looked at it carefully, and then asked his subordinates to ask, and said slowly: "This book is opened in a remote location in the east of the city. There was a rebellion at the shop, and then it was proven to be a spy. The county magistrate Cui who bought the pen..."

Li Yan asked: "If both the buyer and the seller are spies, why should this transaction be recorded in the books?"

Pei Sijian said: "Because low-level spies are not qualified to know the true identity of high-level spies, a high-level spy is valuable, and the fewer people who know the real face, the better."

"When they went to the book store to inquire, they all shirked that they couldn't remember any customers buying pens. This was also the tacit understanding of the merchants, but they didn't expect that Zhang Huan and He would take away the account books directly!"

Li Yan was still puzzled and said: "But County Magistrate Cui is already a Ming government in a county, so there is no reason to follow the thief!"

And as an overtime fisherman, Li Yan still remembers the first time he went to the yamen to interrogate Shi Ming, he was very moved when he saw the county magistrate was still lit with candles in the night, and the magistrate Cui was working overtime inside.

Good officer!
It is absurd to think that such an official would take refuge in Tubo as a traitor.

Pei Sijian said: "I don't believe it either, no matter what, I must investigate!"

After the county magistrate came to take office, the accompanying servants would also be transferred. Zhang Huanhe rushed back to the county office again to transfer the household registration. This time, he was much more careful. portraits.

Holding this painting, Shi Jing gathered the bad guys, walked the streets, looked for witnesses, and determined the specific actions of the slave who bought the pen these days.

Kang Meng went home and reported to Captain Kang, and took countermeasures if necessary.

Pei Sijian's status is too high, some things are difficult to deal with, and they are the local snakes in this county.

In comparison, the outsider Cui County Magistrate has not yet gained a firm foothold.

……

soon.

Everyone reunited in Dudu Mansion.

Zhang Huan opened the household registration: "Magistrate Cui is very simple, and there are only two attendants around him, one is the old slave Tian Gong, and the other is Lu San who bought the pen."

He Jingdao: "They and Cui County Magistrate are both from Huzhou (Wu Xing), and they also speak Huzhou dialect. They have a strong accent and are easy to distinguish."

Shi Jing nodded: "That's true. My brothers checked the streets near the yamen and confirmed that Lu San often hangs out there, and he has written down all the shops he likes to eat. However, Cui County Magistrate often works late, so he I have been waiting at the gate of the yamen, waiting for the magistrate Cui to come out, and lead the horseshoe lamp in front."

Li Yan asked: "In addition to buying five Langhao pens, has this Lu San bought other four treasures of the study?"

Shi Jing said: "I have bought it. This person is generous. Cui County Magistrate seems to like to practice calligraphy. The pen, ink, paper and inkstone are very expensive, and it seems that he is not used to the ones in the yamen. He often buys them in big shops."

If the other party had planned for a long time ago, then doing this would be impeccable.

Li Yan asked: "Does Lu San have a shop that he is used to going to?"

Shi Jing shook his head: "It doesn't seem to be. There are several morning markets and evening markets that have received this person so far."

Kang Meng immediately said: "That's not right, if you have the pen utensils you are used to, why go to other shops?"

"Don't suspect someone of stealing an axe. Maybe they are used to using pens from their hometown, but Liangzhou's pens are just uncomfortable, so they are constantly changing?"

Li Yandao: "At least from the current point of view, just the fact that Lu San bought the pen does not mean that he has evil intentions and used it to make murder weapons."

Kang suddenly showed the look of being taught, but he was a little unwilling.

They didn't dare to doubt magistrate Cui before, but once they did, they naturally hoped that the target was really a spy.

It is also a secret spy, and the meaning of arresting a county magistrate is completely different from arresting a civilian woman.

Because the danger brought by Cui County Magistrate may be a hundred times that of Liniang!
Li Yan was not disappointed at all: "A county magistrate voted for the enemy country. It is definitely not something to look forward to. Besides, Cui County magistrate treats people well. I am quite grateful for the free buttermilk he provided... Wait..."

Li Yan's voice paused, his pupils contracted, and he called the inner guard: "Go to the academy and bring those jars of buttermilk!"

After hearing this, Pei Sijian also stood up abruptly, her complexion changed slightly: "Go to the back door of the Dudu Mansion, hurry up!!"

The inner guard led the way, and after a while, five tall pots were brought in.

There are five schools in the academy, and these pots stand at the entrance of each school for students to quench their thirst.

"Put the buttermilk out of the can."

Li Yan squinted his eyes: "Shi Jing, go and check inside to see if there is a killing mechanism similar to the Langhao pen!"

Shi Jing was stunned.

Li Yandao: "The magistrate Cui set up these pulp buckets in the school to quench the students' thirst. Just think of me as a villain who treats a gentleman's stomach. You should check it carefully."

Shi Jing understood, and when the inner guard had drained the water in the bucket, he leaned in with his upper body, tapping with his hands from time to time, making a thumping sound.

After a while, his voice came from inside: "It seems that something is really wrong!"

He straightened up, turned the jar upside down, pried open the bottom, and said in shock, "It's a dark trough for poisoning!"

Pei Sijian's voice was as cold as a biting wind: "Are you sure?"

There was both fear and uncontrollable excitement on Shi Jing's face: "Absolutely, this kind of dark groove is extremely delicate. When necessary, the poison bag can be placed in it, and the time of poisoning can be set, so it is difficult to trace."

"It's so vicious!"

Kang Meng was furious.

His younger brother Kangda is studying in the academy!
Even when the relationship between the two brothers was at its worst, he never thought of killing his younger brother. How could the county magistrate be so vicious as to tamper with the buttermilk in the academy?

But the next moment, he came back to his senses and looked at Li Yan.

According to his younger brother Kangda, this person seems to like to go to the school early in the morning and drink the buttermilk in the can, right?
"Free is always the most expensive! What a wise saying!"

Li Yan's face was extremely ugly.

He is a dignified Li Yuanfang, he ordered a drink for nothing, and he actually walked through the gate of hell?
Fortunately, these jars have not been poisoned yet, for the simple reason that no one drinks them.

As a child from a poor family, he drinks it every day, and the children of other high-ranking noble families have no interest in this free buttermilk at all.

It is obviously meaningless to poison one of them if it is poisoned inside.

Otherwise, Chapter 1 is over.

Pei Sijian bent down, identified the secret slot, and then compared the list of secret spies, and found that there was indeed a secret spy who was serving as an attendant in the academy, and immediately connected everything:
"Magistrate Cui is waiting for an opportunity. Which drink is more popular in the market? When the time comes, he will order the spy in the academy to change the buttermilk in the jar and throw poison. At that time, the consequences would be unimaginable!"

"Compared to the pervasive penetration of Tubo, my Tang Dynasty is too weak in this regard!"

Li Yan took a breath.

He realized that he had underestimated Tubo after all.

In fact, foreigners are quite good at espionage.

For example, in the Five Dynasties and Ten Kingdoms, when Yelu De Guang occupied Kaifeng and changed the name of the Khitan Kingdom to Daliao, he said this to the old officials of the Later Jin Dynasty: "I know everything about China, but Ru Cao doesn't know about our country."

At that time, the Liao State was able to suppress the ability of the intelligence organization against the Later Jin Dynasty. Later, when Zhao Kuangyin established the Song Dynasty, he immediately set up the Wude Department of the intelligence agency with his cronies. When Emperor Taizong changed its name to the Huangcheng Department, it began to develop with the Liao State. Espionage struggle.

This is also recorded in the official history, China's first full-time spy agency.

Due to the lack of historical materials, the spy organization in Liao Kingdom can confirm its existence, but its name is unknown, but its pervasive infiltration undoubtedly caused huge troubles to the Central Plains.

The Tubo in this world must not be underestimated. After all, there were inner guards in the Sui and Tang Dynasties, and they dealt a huge blow to the surrounding alien races. They learned from the pain and naturally retaliated.

On the other hand, the current internal guards are not professional enough. After this encounter, Li Yan completely abandoned luck and looked coldly:
"That being the case, let's fight hard for our respective countries!"
