Intelligence has become a science in later generations, and many professional scholars are researching, and many colleges and universities have also set up the discipline of information science, which is enough to prove that information science is a complex and comprehensive science. It is undeniable that intelligence is important to every force in every era, and it has a certain role in promoting human economy, economy, culture, military, science and technology, and so on.

It was not too late for Liu Feng to set up an intelligence agency at this time, he knew that such an intelligence agency was sometimes a double-edged sword, so when the structure was created, the first person in charge of the organization, the first batch of "guards" and the structure of the organization, etc., were very careful.

He chose the most intimate two brothers, Liu Yanbo and Liu Yanying, and when Liu Yanbo was training recruits, he asked him to choose suitable candidates for intelligence, and after strict examination, a total of more than 100 people became the first batch of "guards".

Liu Feng asked the internal guard, the action of intelligence, to achieve the "wide, fast, accurate and hidden" five-character decision, Liu Feng knew that in the later society, the education of information science, was developed on the basis of the library, and the intelligence force he wanted to build was not only a unit that could only explore intelligence, but also to set up a scientific and perfect department, so he established a bookstore in the north of Yucheng, reserved to copy and print books, but also to lay the foundation for the training of internal guards.

Liu Feng was even more hands-on in the training of the first batch of "guards", and he trained them one by one in courses such as intelligence collection, processing, reporting, retrieval, and research services, and he did not want the "internal guards" he had worked so hard to establish to be as notorious as Jinyiwei in the future.

Moreover, Liu Feng knows very well that the cost of intelligence work is huge and the development time is long, but fortunately, Liu Feng is still young, and the seeds he planted can play a key role in ten years, and it will not be in vain for his hard work.

In the establishment of internal security institutions, Liu Feng set up four places,

The Bird's Nest is responsible for training intelligence officers in various departments and arranging intelligence tasks, with Liu Feng in charge for the time being.

The Hummingbird Department is responsible for the intelligence collection of military and civil affairs outside the jurisdiction, such as: geological survey, land opinion, national politics, economy, science and technology, etc., and Liu Yanbo is in charge.

The Thunderbird Department is responsible for the actions taken after intelligence collection, and each is mainly responsible, and Liu Yanying is responsible for the defense and counter-reconnaissance in the jurisdiction.

The Ministry of Culture and Birds is responsible for the collection and management of intelligence materials, as well as the analysis and judgment of comprehensive intelligence, and is also responsible for the collection of civil affairs information in the jurisdiction.

Liu Feng's series of actions did not hide from the inside and outside, but the "guards" of the internal guards were too ordinary, they were uniformly dressed in soap clothes, and they were not much different from ordinary officials, and when these "guards" really played a role, they also shocked everyone.

After the three passes in the north, the Khitan was a little abnormal and did not have a large army to go south, which gave Liu Feng enough time to train, in the Yucheng military camp, a scene in full swing, whether it was a recruit or a veteran, they were in full swing training, about the training of the internal guard Thunderbird Department of action guards, Liu Feng was personally supervised, in the combat training of the squad, those raids, kidnappings, assassinations and other novel training subjects were staged one by one.

……

It's winter, and there have been a few light snowfalls.

Khitan, crossing the camp.

Yelu Ruan sat in the big tent, looking unhappy, his father Yelu Bei opened the eldest son of the emperor Yelu Abaoji for the Khitan, because his mother Shu Luping favored the second son Yelu Deguang, and loved the youngest son Yelu Lihu, so he was forced to abandon the country and run away from the road of no return, Yelu Bei took the Han favorite concubine Gao Meiren and other part of the dependents, sailed on the sea in Liaodong, and went to the Southern Tang Dynasty.

And after Yelu Deguang died of illness in Luancheng, the Khitan minister Yelu roared, Yelu Ambo and others supported him to ascend the throne.

However, his grandmother, the Khitan Empress Dowager Shu Luping, did not want him to ascend the throne, and insisted on letting his youngest son Yelu Lihu ascend the throne, so Yelu Lihu led troops to conquer him, the newly enthroned Khitan Emperor.

Although with the help of Yelu Roar and others, he defeated Yelu Lihu, but the Empress Dowager Shu Luping was not so easy to get along with, as early as after the death of Yelu Abaoji, Shu Luping was regent in the name of the queen and was in charge of military affairs. When Yelu Abaoji was about to be buried, Shu Luping cut off his right hand and put it into Yelu Abaoji's coffin as a burial.

Such a ruthless man, how can he get along well, personally reorganize the soldiers and horses, and Yelu Lihu led the army to garrison the crossing of the Huang River, and the armies of both sides resisted each other across the riverbank. And now the news of the Hedong Army's Cizhou Army recovering Mo Erzhou in the north and rebuilding the three passes in the north has come from Nanjing Xijin Mansion, but fortunately, Liu Feng's army did not continue the northern attack, which also left Yelu Ruan room for relief.

At this moment, how can he be happy, he, the Khitan emperor, can be said to be in internal and external difficulties. Fortunately, at this time, Yelu Wuzhi, who was born in a noble family, stepped forward and came to persuade Lu Ping to make peace with Yelu Ruan.

……

In Shu Luping's big tent, the atmosphere was calm.

Yelu Wuzhi is a Khitan royal family, his personality is simple and quiet, rich in tools and insight, and he is knowledgeable, proficient in astronomy, not only a general who leads the army, but also a talent who is well-versed in literature and ink.

As an important minister of the Khitan Three Dynasties, his prestige is enough to compete with Shu Luping, and he is neither afraid of the Queen Mother's suspicions, nor of Yelu Ruan's prestige. Under the persuasion of him and other important ministers, the grandfather and grandson finally met, but neither side wanted to let go.

In the noise, Yelu's house was also aroused by this stubborn and greedy grandson, and Zhengse said: "If you can't talk about it, how about another bloody battle, anyway, the dead and wounded warriors are all from the Yelu family." ”

Jeruwu said and walked away.

Leaving the embarrassed crowd in vain, and the threat of Yelu House is extremely useful, he has a decisive prestige in the Khitan country, forced by public opinion, and considering the power of the Yelu family, the Empress Dowager Shu Luping did not dare to be stubborn anymore, so he agreed to make Yelu Ruan the emperor.

……

Guo Wei of the Hedong Army of the Western Expedition also gained something, he built a fence on the periphery of the city in the river, divided the troops to besiege, and the section of the river made Li Shouzhen break through the siege repeatedly, all of which were thwarted, and the city in the river has also been besieged for more than a month, Guo Wei's tactical strategy, once again effective, and with time, the city in the river can be broken.

Liu Feng also sent the support of arrows and weapons to the Hedong Army in real time, it was not that the Hedong Army lacked these, but that Liu Feng wanted to sell a good one with Guo Wei, he knew that after the Hedong Army went west, it must be the neighbor of the most prosperous soldiers and hundreds of thousands of elite soldiers, Liu Feng had to be careful.

From the bottom of his heart, Liu Feng put himself and Guo Wei in the same position, saying that the burden of shouldering the nation is a little too big, and perhaps it must be the support of the villagers under his rule. In just over a month, Liu Feng and Guo Wei have been in constant correspondence, and the two have a bit of a feeling of friendship in previous years, and they are also teachers and friends. In the letter, Liu Feng and Guo Wei had a lot of exchanges on governing the army and the people.

What Liu Feng didn't know was that Guo Wei also let Chai Rongguan a lot of letters, which also made Chai Rong more and more interested in Liu Feng.

No matter how interested Liu Feng was in him, he finally began to develop the "artillery" weapon for the Zhaoyi Army to attack Yucheng.
