The first victory after the breakthrough of the army was greatly boosted, and Li Zicheng feasted all the soldiers that night to express their congratulations.

The banquet was quite grand, and although the tables and chairs were not sufficient, the soldiers and generals who attended the banquet still enjoyed it, padding the ground with cowhide cloth and sitting cross-legged, watching the food and wine brought by the women of the rear camp.

Li Zicheng made a very generous move this time, slaughtering all the cattle and sheep in the rear camp, not only that, but also all the fine wine that had been seized (looted) over the years was put out, and the entire camp was brightly lit, except for some scouts patrolling the periphery, there was almost no vigilance.

Ma Xiangzhen's head was cut off, his eyes were still staring at him, his mouth was slightly open, as if he had begged for mercy before he died, and his head was hung on a wooden pole by the invading army, hanging high, looking particularly hideous and terrifying.

In the midst of the welcome and encouragement of the camp, only Li Yan sat in the corner thoughtfully.

He had already sensed that something was wrong, Li Zicheng marched quickly, and the Ming army had no time to react, so there must be no scout tail pursuit, after entering Nanyang, Li Zicheng made a decision not to fight Nanyang, and did not commit any crime against the county town of Nanyang, and the Ming army could not easily obtain the trajectory of his army.

Even if you get it, you can't catch up.

However, Ma Xiangzhen is different, he is blocked in advance on Li Zicheng's only road, which is very intriguing, if he is not a person in the camp, how can he know how to march? What's more, the marching route is still a plan that can only be clear to the top management, how can it be guessed by the Ming army?

It is true that it is indeed possible that Ma Xiangzhen happened to bump into Li Zicheng's army, but the safety of the whole army cannot be blocked by "luck".

The high-level leaders of the Chuang army are all Li Zicheng's cronies, and Li Yan believes that it will definitely not be the high-level problem, if there is a problem at the high-level, then they will not even be able to get out of Yufushan.

It's not that the top level is not necessarily easy, if a detailed work in the camp can deduce the strategic plan of the invading army based on fragmented and scattered information, then this is an intelligence genius, and such a person will have a big incident sooner or later if he stays in the intruding army!

Now Li Yan and Chuang Jun share weal and woe, and they absolutely cannot allow such a situation to occur.

Li Zicheng was very happy, after all, he won the Ming army for a while, and swept away the haze of the previous fish recovery, his self-confidence returned, catalyzed by this emotion, the wine was a cup of belly, and his face was flushed after drinking, and he was holding Liu Zongmin's hand and boasting to the generals of the army.

Liu Zongmin's killing of Ma Xiangzhen this time can be regarded as a great achievement, and Li Zicheng also began to re-trust this old brother who was "unruly" and now "repentant".

At this moment, Li Yan took the wine glass, walked away with a smile, and when he saw Liu Zongmin, Li Yan still raised his glass politely and said: "Mr. Liu, there were many misunderstandings before, and I hope that Mr. Haihan is still in charge." ”

Li Yan didn't want to offend Liu Zongmin too much, not to mention that Li Zicheng's intention to protect himself was obvious, so he also faintly had a plan to make peace.

However, Liu Zongmin obviously didn't think so, he snorted coldly, didn't give Li Yan any face, didn't pay tribute to Li Yan at all, just sneered and said: "Mr. Li is good at archery, I will definitely try to compete with Mr. when I have the opportunity in the future." ”

Li Yan frowned slightly when he heard this, he knew what Liu Zongmin meant, he shot him with an arrow before he held a grudge, and this person who was not very big did not accept his olive branch.

If you don't accept it, you won't accept it, Li Yan didn't mean that he had to lick Liu Zongmin, so he still said with a smile on his face: "Mr. Liu has a good reputation, and next time I will definitely take out ten successful husbands for the chief whistle to observe and guide." ”

Liu Zongmin's face suddenly turned gloomy when he heard this, Li Yan's threat was quite strong, he thought that Li Yan was afraid of him and came to sue for peace, but as a result, he threatened him with his backhand, and was about to ridicule him, but was stopped by Li Zicheng.

"It's all my own brothers...... Don't hurt your peace...... Jie Xuan, Mr. Li Yan is a great talent, you learn more from him, don't just rely on martial arts to do things......" Li Zicheng was obviously a little slurred, and he was talking drunk intermittently.

Liu Zongmin stopped talking when he heard this, and arched his hand towards Li Yan quite unconvinced, Li Yan was naturally not such a reckless man with such a happy and angry look, and still returned the salute with a smile on his face, as if the two of them had really released their previous suspicions.

"King Chuang, his subordinates have important things to report, please move to King Chuang." Li Yan restrained the smile on his face and bowed his hand.

Li Zicheng obviously didn't want to talk about military affairs at this moment, but just waved his hand and said: "Today is a time for a happy gathering, don't talk about military affairs, don't talk about military affairs, what is there tomorrow." ”

"King Chuang, this matter is very important, and his subordinates must report it now!" Li Yan raised his voice a little.

Although Li Zicheng glanced at Li Yan twice when he heard this, he didn't change his mind, but just asked, "Is it really important?" ”

"The subordinates suspect that there is a small ...... in the army," Li Yan said in a low voice.

"It's normal to have some fine work, and it doesn't hinder anything" Li Zicheng thought it was a big deal, but he waved his hand indifferently.

Meticulously, there is nothing strange for a peasant rebel army like Li Zicheng, there are so many defectors who surrender every year, and there are many who rebel after surrendering, these people often bet on both ends, and everyone understands the dirty transactions with the imperial court in private, and this matter is not easy to investigate and cannot be investigated

When Li Yan heard this, there was a black line, well, after engaging in it for a long time, he did not have the awareness of guarding against spies at all, but this is certainly unreasonable, and the value of intelligence is unimaginable in a war, especially in a large-scale war.

So Li Yan immediately bowed his hand and said: "King Chuang, Sun Tzu has a saying: 'Ming Jun is a virtuous general, so he moves and wins, and success comes from the many, and the prophet is also.'" The prophet shall not be taken from ghosts and gods, nor from things, nor from the degree, but from men, and from those who know the feelings of the enemy. If I want to win a decisive victory in the world, I can't underestimate the role of the intermediary, and now not only do I not set up my own intermediary organization, but I also don't guard against the spies of the Ming court, I am afraid that sooner or later I will suffer a big loss here! ”

Li Zicheng eats this set the most, move an ancient immortal, and then point out the problem of breaking into the army according to his words, you can directly catch the point that Li Zicheng cares about.

Sure enough, Li Zicheng's expression was a little more serious, and then he said: "A meticulous work, do you really have such a great ability?" ”

"King Chuang, Ming Taizu has set up Jinyi Guard, and later Emperor Ming has set up East and West Inner Factories respectively, even figures like Ming Taizu attach so much importance to the role of intelligence, can King Chuang still ignore it?" Li Yan said solemnly.

Zhu Yuanzhang's background can always resonate with Li Zicheng, so for Zhu Yuanzhang, Li Zicheng has some respect in it, so he was really relieved when he heard the words.

"Brother Li Yan, all the soldiers at today's banquet, I can't be there, in this way, this token is given to you, you discuss it with Gu Zuoshen, get an idea, and take this token to do it, this token is in hand, and there must be no obstacle in the camp." Li Zicheng thought for a while, reached out and took out a token from his waist and handed it to Li Yan.

The camp is not rich, the tokens are all made of iron, and Li Zicheng's tokens are a little blackened.

Li Yan was overjoyed to take the token, Li Zicheng had always used him as a staff officer before, and now he gave him this token, which can be regarded as giving him some permissions, this is a good start, he is not willing to be a staff officer who can only give advice all the time.

After thanking Li Zicheng, Li Yan took the token and went to Gu Junen, who was practicing calligraphy.

Gu Junen doesn't like this kind of banquet, as a literati, he can't play with a group of reckless people, but it's a pity that he has no fame and can't play with literati, so he has to break into the camp.

Seeing Li Yan coming, Gu Junen hurriedly greeted him, Li Yan was one of his few bosom friends, after all, he had no fame, he could read and write, and his manners were quite decent, not like those reckless men.

After a few words of greeting and laughing at the rudeness of the generals who broke into the camp, Li Yan cut to the chase.

Throwing the token given by Li Zicheng on the desk, he said: "This time, I was ordered by King Chuang to negotiate with Brother Gu to find a way to clean up the court in the camp, I don't know if Brother Gu has any ideas?" ”

When Gu Junen heard this, he thought about it for a while, and said: "Brother Li Yan, it's not me who poured cold water on you, there are many homeless people in this camp, and it is not easy to handle it if a few eagle dogs from the imperial court come in." Besides, as long as there are no problems at our top level, it doesn't hurt to have some fine work at the bottom. ”

"Brother Gu's words are wrong!" Li Yan said with a straight face: "Brother Gu, didn't Brother Gu see the problem in the encounter between Ma Xiangzhen and our army this time?" ”

When Gu Junen heard this, he frowned and said, "You mean that the fine work has leaked our army's course of action?" ”

"Brother Gu, we can't afford not to guard against it, Ma Xiangzhen is only two thousand people, and our elite army can deal with it, what if it is Yang Sichang's main force next time? So what do we do? When the time comes, I'm afraid that I will inevitably be defeated and die! It has been more than 200 years since the imperial court set up factory guards, and although it is in decline now, it is not without talents......" Li Yan said slowly.

Sure enough, these words made Gu Junen ponder, and he nodded and said: "If you say so, then you really have to pay attention to it, if there is really such a powerful work, I am afraid that it will not be my blessing to break into the army." What is the gentleman going to do? ”

Li Yan thought for a while and said, "Everything is fine, but there must be two things. ”

"Which two?" Gu Junen asked.

"First, you must contact the outside world, if you can't contact the outside world, then naturally you can't pass on intelligence" Li Yan has watched a lot of spy war dramas, and he knows some basic operations very well, and now there is no such thing as a radio transmitter, and the transmission of intelligence can only rely on manpower, and relying on manpower requires connectors.

Gu Junen thought for a while and said: "The messenger must not be the one who broke into the camp, if the person who broke into the camp went out every ten days and a half and didn't come back, the military law would not allow him." ”

This is also what Li Yan thought, I am afraid that the means of this spy still rely on the elements outside the camp, but there are many people who break into the camp without anyone entering and leaving the camp, and it is easy to investigate.

"And what about the second one?"

"Second, this person has to be literate, and if he is illiterate, he will not be able to write information clearly, and it is easy to make mistakes and omissions simply by relying on language transmission." Li Yan tapped his fingers on the case table and said.

"This is a breakthrough point," Gu Junen said: "There are not many people who can read and write in the entire camp, and it should be clear if you check them all." ”

"I don't have to tell you that he is literate," Li Yan shook his head and said.

"Yes, what should I do according to Brother Li's wishes?" Gu Junen knew that Li Yan was a scheming person, so he immediately leaned forward and asked.

Li Yan naturally already had an idea, so he smiled and said: "Then we have to trouble Mr. Gu to write some words and post them in the barracks, and we will secretly send reliable people to observe and see who has read these words, and then secretly track them down, thinking that this fine work will also show its feet." ”

At this time when the literacy rate is very low, those who can read are not ordinary people, and these people will always subconsciously take a look when they see the notice, even if they are disguised as illiterate spies, they always glance at each other, and Li Yan gambled on this glance.

In this era, there is no systematic espionage training, and the detailed work is often based on summarizing experience by oneself, and this also makes the counter-espionage methods of this era seem quite simple and crude.

Gu Junen also felt that this plan was very good when he heard this, patted his thigh and said, "That's it!" They should also be instructed to keep an eye out for suspicious characters wandering around the periphery. ”

"Yes" Li Yan was very satisfied with Gu Junen's point, and immediately nodded, and affirmed with a smile.
