Start with detective Li Yuanfang

Chapter 41
"Is this the list of Tibetan spies in Liangzhou?"

"Qiu Ying was seriously injured. Two of the inner guards defected and joined the enemy. That noble lady Su Pi also died of poisoning after she surrendered?"

Pei Sijian, governor of Liangzhou, looked at the list that Li Yan took out, and then heard what happened last night, his face was full of shock.

He knew that the matter was of great importance, so he immediately ordered the mobilization of manpower: "Li Wuwei, this time to arrest the spies, your internal guards will be the main ones. The Governor's Mansion and Guzang County Government will fully cooperate, and Zhechong Mansion will immediately deploy troops."

Li Yan's eyes were bloodshot, he didn't sleep all night, but he didn't look tired, on the contrary, he had a resolute spirit, and said, "Thank you, Dudu Pei, I suggest closing the city gate directly, prohibiting entry and exit, and arresting all the spies. Open the city gate again!"

"City closure?"

Pei Sijian looked solemn and hesitated.

Li Yan nodded: "Pei Dudu, I know that Liangzhou is the throat of the five counties, an important place for commercial routes, and the daily market exchanges with merchants, and the closing of the city gate is very important, but it is precisely because of the importance of Liangzhou that the arrest Secret spies are more important! I am willing to take responsibility for this city closure!!"

Either don't do it, or do it absolutely.

He wants to catch everything.

Hearing Li Yan's eloquent words, Pei Sijian looked at the list carefully again, and slowly got up, her old eyes glowing brightly: "Okay! Li Wuwei, I believe you! Close the city gate and arrest the spies!"

With this order, the whole Liangzhou moved.

The personal guards of the governor's mansion, the soldiers of the Zhechong mansion, the inspectors of the internal guards, the servants of the government office of Guzang County, bad people...

All out.

Among them, the county government officers came to the eight city gates and issued orders to close the gates, and Zhechong's soldiers and the Dudu's personal guards guarded the main streets.

It is the internal guards and bad guys who actually carry out the arrest.

Restaurants, restaurants, bookstores, pharmacies, post stations, schools...

The secret spies on the list provided by Liniang, although they are all middle- and lower-class ordinary people, and have no high-school children, but they are widely distributed, and they can be said to be of all kinds.

Such an intelligence network can investigate people's livelihood very well, and prepare for Tubo to launch a war at a critical moment.

In fact, a few years after the original history, Tubo led an army to raid Liangzhou, intending to pass through here and occupy the entire Longyou.

War is the final word, and all kinds of preparations before the war are the factors that determine the outcome, and secret spies have also made great contributions.

Because of this, Li Yan treated everyone equally, no matter if it was a real list or a fake list, they were all brought back.

On the fake list, some people looked dazed and yelled that they were wronged, while some people had a guilty conscience and fled crazily...

On the real list, some secret spies showed panic and were caught limp, while some secret spies stood up and resisted...

Those who resisted, those who could be captured alive were all captured, and those who were highly skilled and dangerous were shot by bows and crossbows.

Either cut off limbs and disable them on the spot, or directly kill them without mercy!
For a time, the long street was covered with blood!
In order to arrest a mere hundred people, nearly three thousand soldiers were dispatched.

But the effect of this determination is also immediate.

It only lasted for less than an hour, when the school just started, the normal arrest operation was over.

"Report to Commander Pei and Li Wuwei, who are suspected members of the Tubo secret agents. Ninety-one people were arrested, thirteen were killed, and the remaining two are still at large. They are trying their best to arrest them."

"very good!"

Pei Sijian stroked her long beard lightly and breathed a sigh of relief.

With a thunderbolt, Li Ting swept the hole, and the secret spy network that Tubo spent at least several years and countless painstaking efforts in Liangzhou has been declared disintegrated.

Even with Pei Sijian's city mansion, she couldn't help but smile brightly: "Li Wuwei, this time I'm in your honor!"

Li Yan said in a sonorous tone: "With the support of Mr. Pei, we won this victory. Dafeichuan's disastrous defeat will never happen again. In the future, our Tang army will definitely win a big victory over the bandits, so we can feel proud!"

"Good ambition!"

Pei Sijian's spirit was lifted, and she said sincerely: "This old man really envies Leader Qiu Ge, he can have such a competent subordinate like you, God helps the inner guard, God helps the Tang Dynasty!"

After being happy, Li Yan restrained his smile again: "However, this operation is to arrest low-level black disks. Liniang's online is probably the leader of Tubo in Liangzhou. This person has trained a large number of black-clothed killers, which is extremely harmful. Daddy, if you can’t catch this person, you won’t be able to reach Consummation in the end!”

Pei Sijian said in a concentrated voice, "Any clues?"

After the chaos in the inner prison, Li Yan thought for a night with the wisdom of ordinary people, carefully deliberated, and sorted out a lot of clues: "Xiao Ling asked me for credit the day before yesterday. He was promised a lot of profit by the enemy and temporarily instigated rebellion."

"The thieves were divided into two groups. They ambushed and killed me along the way, and went straight to the inner guards all the way. They launched very hastily, which just proved that they were chaotic and we were cornered!"

After Pei Sijian inquired about many details, she pondered and said, "Yuan Fang's analysis makes sense."

"The other side plotted against Xiao Ling. They could have secretly conspired with the female spies. They decided to cooperate internally and externally before launching an attack. What happened last night was indeed too hasty. If Commander Qiu had a few more people around him, the two traitors might fall short..."

"The old man has a guess. Did you do something unintentionally to force the thief to do it in advance?"

Li Yan frowned: "I also had similar thoughts, but I really can't figure out what it is..."

Just at this time, the personal guard notified that Kang Meng and others had arrived.

The home and the inner guards were attacked at the same time, which made Li Yan vigilant. He was about to mobilize all forces at this time, so when he came, he asked Kang Meng and others to come together and work together.

Also give them a chance to show their faces: "Pei Gong, these few self-proclaimed detectives have seen through the murderer's arrangement in the Liangzhou post house, and the murder in the secret room has been solved!"

"Oh? Why didn't magistrate Cui tell me? Then I want to see you!"

Pei Sijian became very interested.

Kang Meng and his party were brought up and bowed to salute: "I have met Governor Pei, and Captain Li!"

Facing Pei Sijian, a third-rank official, they were undoubtedly restrained a lot. Li Yan smiled and said: "Pei Gong is very appreciative of your investigation of the Tubo ambassador's case. Don't be nervous, and explain the reasoning process again."

"Yes!"

As soon as these words came out, they became even more nervous, but they also showed uncontrollable excitement.

Pei Sijian gave a few words of encouragement, and after looking at the blueprint of the murder tool, she immediately understood the truth of the secret room, and frowned slightly: "The thief is cunning!"

Kang Meng said respectfully: "Following Li Wuwei's instructions yesterday, we searched for clues from the source of the materials, searched a lot of shops and bookstores, and put together all the recent books, hoping to find clues and catch the murderer who made the hidden weapon... "

His words were originally reciprocal, in order to highlight Li Yan's contribution, but Li Yan frowned when he heard this: "You didn't ask questions, you just searched the account book?"

Zhang Huanhe stepped forward and said timidly: "What Li Xiaowei said, it's like this..."

The two of them were first introduced to Li Yan by An County Captain. An County Captain assigned Hu Cao, who was in charge of taxation and household registration.

This time, in order to investigate the case, they directly took away the recent account books of the shop, and after checking, they notified the merchant to go to the Yamen to pick it up.

No one thinks this is overbearing, the status of the merchant is very low, and it is a normal operation.

Li Yan asked again: "Then what do you want to check through the ledger?"

Kang Meng said: "We don't understand the mechanism of hidden weapons, but since the murderer wants to make killing tools, he always needs a pen!"

"Furthermore, the mechanism required for this kind of hidden murder weapon is extremely delicate, and it cannot be accomplished once. It may require multiple trials, and the murderer may buy pens multiple times."

"Through the little officials in the post house, I found out that Nianzheng envoy of Tubo doesn't like Zihao brushes, but prefers Langhao brushes, and also likes to use Beibi brushes."

"Shi Jing asked the shop of the bookstore (the owner of the bookstore) again, and then realized that the Beibi used wolf hair inside and rabbit fur outside, but the body is thicker and blunter, and the pen shaft is thicker. Tibetans should like that style. "

"So we specifically selected shops that sell Langhao Beibi, but we asked a few, and those shops couldn't remember clearly, so we simply asked Zhang Huanhe to take back all the books of all the big shops that sold pens. I checked slowly in the book, and the valuables are all marked with the customer's name, which can be returned or exchanged."

Hearing this, Pei Sijian's eyes lit up immediately: "Bring me the account book and check it immediately!"

"Let's get it!"

Zhang Huanhe ran errands in a hurry, and after a while, he carried a tall stack and returned.

Everyone wanted to flip through the books, but Pei Sijian said: "Don't bother, compare the spy list and check those shops first!"

Li Yan nodded: "Mr. Pei is smart. Only the secret spies of Tubo will report the news of our tracing of raw materials. If the murderer really shows a flaw in this aspect, they will jump the wall in a hurry and launch an attack that night!"

Kang Meng watched from the side, secretly admiring.

Too much to highlight the wisdom of leadership.

With a clear goal, it will be much easier to carry out the work.

Everyone worked together, and quickly found four account books.

These four shops and bookstores that sell pens are all suspected to be operated by Tibetan spies, and the scope has been reduced all of a sudden.

With good eyesight, a few people who could read began to read, even Pei Sijian was no exception.

"Langhaobeibi...Langhaobeibi...here is one!"

"There's one here too!"

"This store sold two!"

"Huh? I sold five of them half a month ago, and they were bought by one person!"

Shi Jing suddenly called out.

But before Li Yan and others walked over, he looked at the name of the customer who bought the pen, but was suddenly stunned: "How could it be Lu San?"

Kang Meng's eyes were fixed: "This name seems to be a servant, who is his Alang?"

Shi Jing raised her head, and frowned, "I...I dare not say..."
