There are only a handful of people who know the identity of 'Hongyan' in the entire Great Song Dynasty, and this intelligence agent is personally controlled by Zhao Ta, the boss, who has a one-line contact, and the people in the Intelligence Department only know his name but not his person, but he is a newly rising legend in the intelligence community. He not only sent back the political and economic information of the Jin State, but also transmitted back the high-level movements and decisions of the Jurchens, and the most legendary thing is that he not only obtained the information on the survival of Emperor Jing Kang in the Jin State, but also sent back a personal letter written by him to the emperor, which made a great breakthrough in the intelligence work of the Jin.

But the appointment of this Hongyan at the beginning also made a few insiders admire the emperor even more, speaking of which was only due to a conversation between Zhao Ta and Gao Chong, talking about the Song ministers who were taken captive to the Jin State, some of them called the high-ranking officials of the Jin State to forget their ancestors and be willing to be lackeys, and some people have always kept the festival and refused to submit to the obscenity of the Jurchens, and still cared about the Great Song Dynasty and did not forget to return to the south.

Gao Pet talked about one of his brothers, this person is named Gao Shitan, and he was at the same time after the Song Dynasty minister Gao Qiong, although the two were close but not familiar with each other, Bianjing City was taken away by the Jin army when it was broken, and at this time he was also an official in the Jin State, and he was appointed as a bachelor of Hanlin, which disgraced the whole family and removed him from the family tree. A few days ago, he sent back a letter saying that although he was an official in the Jin country, he also cherished his homeland and hoped to do something for the country.

Saying that the unintentional listener was intentional, Zhao Ta had been suffering from not being able to obtain information about the Jurchen high-level in time, so he immediately ordered Gao Zhong to write a letter to his clan brother, saying that if he sincerely served the motherland, he could recommend it to the emperor with a thousand needles, correct his name, and return his innocence when he returned to the south. Unexpectedly, after the letter was sent, Gao Shitan really sent back some information about the high-level struggle of the Jurchens. After the investigation by the Intelligence Department, it was proved to be true, so the two sides set up a line. He was assigned as a senior secret intelligence officer in the Intelligence Division, codenamed 'Blue Bird'.

The two sides came and went. Zhao Ta soon found that the information provided was unavailable with Gao Shitan's identity and status, and he was suspicious but did not want to give up this line, so he sent Li Jun to the Jin Kingdom to investigate the matter in person. The result of the matter was expected, and it was beyond everyone's imagination, the person behind the Blue Bird was actually - the traitor of the Great Song Dynasty and the important minister of the Jin State, Yuwen Xuzhong. Li Jun met with him through Gao Shitan, and Yuwen showed him his heart and was willing to contribute to the Great Song Dynasty.

This matter makes people feel too ridiculous, an official who has been repeatedly excluded and degraded in the Great Song Dynasty has been reused and trusted like never before in the Jin State. obtained the status and wealth that could not be obtained in the Great Song Dynasty, but he was still willing to contribute to the country regardless of his previous suspicions, how can people believe it! Li Jun did not dare to call the shots, and immediately reported the matter to the emperor when he returned to China, he thought that Yuwen Xuan might be a spy planted by the Jin State, and used Gao Shitan to provide false information to the Great Song Dynasty in order to achieve the purpose of influencing the decision-making of the Great Song Dynasty.

Li Jun's suspicions were not unreasonable, and many of the espionage cases they uncovered were bought and appointed by the Jin State by the Great Song Dynasty people and officials who returned to the south. Collect intelligence for the Jurchens in the name of returned righteous soldiers. And Yuwen Xuzhong was subject to his golden order, and he set an official system for it, drafted amnesty and enjoyed wealth. It is very likely that he is pretending to take refuge in the service of the Jurchens, but he is just doing it more secretive and advanced!

Zhao Ta had other ideas, and when he read history in his previous life, he found that Yu Wenxuzhong, the minister in the late Northern Song Dynasty, was a very strange person. He has both a biography in the "History of Jin" and a biography in the "History of the Song Dynasty". There are legends of Zhao Ta in the two histories of the Song and Jin dynasties, and there are two people who know about the Tao. One is Zhang Jue, and the other is Guo Yaoshi. Guo Yaoshi is included in the normal biography in the "History of Jin". In the "History of the Song Dynasty", it was included in the "Biography of the Traitorous Minister". Zhang Jue was even more miserable, not only was he a neighbor of Guo Yaoshi in the History of the Song Dynasty "The Biography of the Traitorous Minister", but he was also included in the "Biography of the Traitor" in the "History of Jin". Only Yuwen Xuzhong is different, not only does he have a biography in the two histories, but the histories on both sides have a good evaluation of him. That is, both sides consider him their own.

Isn't this a plot that often appears in spy movies? A successful double agent gained the trust of both hostile parties, and both awarded him medals and erected tombstones. Zhao also doubted that in a feudal dynasty with a strong emphasis on loyalty, could a person with a traditional Confucian education really be loyal to two rival courts? Is Yuwen Xuzhong's surname "Song" or "Jin"?

"Life is a dead and idle thing, and you will not forget it when you crack your chest." These are two sentences of one of his own poems transcribed by Yu Wenxuzhong in a letter to Zhao Ta, and this poem also made him make up his mind, how can a person who has such a deep affection for his family and country, and a person who smiles at death so much, be greedy for life and afraid of death, and pursue wealth and glory. So there is one more meritorious intelligence officer in the intelligence department - Hong Yan!

In constant contact, Yuwen Xuzhong knew that among the Han people who were officials in the north, there were many people who were dissatisfied with the Jin State, so he began to secretly make friends with these people, began to establish his own personnel and intelligence network, and collected more information.

Facts have proved that Zhao Ta's judgment is right, and Hongyan can also stand the test. In fact, the Yuwen Void Center has greater ambitions and endures humiliation in order to achieve great things in the future. His official became bigger and bigger, and he came into contact with a large number of government documents of the Jin State, so he not only learned a lot about the internal struggles of the Jin State, but also sent people to tell him the truth of the Jin State with secret letters, and every time the Jin people invaded the south, he also tried every means to dissuade them, and he was really in the Jin Ying's heart in the Song Dynasty.

Now Yuwen Xuzhong has sent back the views of the high-level of the Jin State on the current war situation, and decided to 'first pass outside the customs and then inside the pass, first Liaodong and then Nanjing'. Zhao Ta was overjoyed, the news came too timely, at least it showed that the Jin State had not yet learned the truth here, and still dealt with the current situation on the basis of the news sent back by Qin Hui, judging that the Song army sent naval forces to harass in Yingzhou and Liaodong was just a show of force, and wanted to further gain benefits in the negotiations, but only ordered the Wushu to mobilize forces and quickly expel the enemy in Yingzhou, so he could use the time difference between the information transmission of the Jin State to complete the deployment and achieve his campaign goals...

Zhao Yan suddenly received a letter from the emperor Feige, ordering him to stop withdrawing troops in the direction of Datong, stop the battle plan to lure the enemy into depth, and immediately launch a full-scale counteroffensive against the Jin army that invaded Fengshengzhou, and strive to annihilate the enemy. Zhao Yan was a little frustrated when he received the order, he had laid out such a big game, and the fish had already bitten the bait, as long as he waited for the Jin army to completely enter his ambush circle in two days, he could hit them hard in the northwest.

"Dutong, the Hunting Cavalry Brigade sent news, and the Jin Army suddenly stopped following up and turned eastward, as if it had the intention of returning to Yanjing!" Zhao Yan regretted that his plan was terminated by the emperor, but the iron law of military orders had already soaked every cell of him, and just as he was about to adjust the deployment, a personal soldier entered the account and announced.

"What, the Jin army suddenly retreated?! Did the vultures see through our plans, or did the actions of the Hunting Cavalry Brigade reveal a flaw! Yelu Yu looked at Zhao Yan suspiciously and asked.

"Your Majesty is really strategizing, and the decisive victory is thousands of miles away!" Zhao Yan handed the emperor's order to Yelu Yu and said, "Zhao Yong's army has conquered Zhuozhou, annihilated most of the Yanjing garrison Zongfu department, and the Jin army retreated to Yanjing; The emperor expected that Zongfu would send a messenger to report to Wushu, and Wushu learned that Nanjing was lost, and Yanjing was in danger, and he would definitely return to support Yanjing, which was much more important than Datong..."

"It's no accident that Your Majesty can have today's achievements!" Yelu Yanxi also sighed after seeing it, and was more convinced of Zhao Tan, but the enemy's situation had changed, and they had to make a countermeasure as soon as possible, "In order to conceal our strength and show the enemy to be weak, our main force has retreated too much, if the Jin army retreats with all its might, we will not be able to intercept the enemy brigade!" ”

"Now the front army of the Jin Army has passed Jiming Mountain, and our Longyi Army has penetrated into the area of Alum Mountain out of Songzikou, and it is still two hundred miles away from Juyong Pass. The three cavalry brigades of the Lion Wing Army and the Hezhong Army have already detoured back to the right flank of the Jin Army and are waiting in the Xishan area, only they are the closest to the Jin Army, but they are also a hundred miles! Zhao Yan looked at the map, his brain was running fast, thinking about countermeasures.

The emperor's intentions are already very clear, once the Jin army begins to retreat and begin to attack Yanjing, and after the reinforcements of Wushu arrive, they will fight a decisive battle with it in the city, which will have to fight two major battles in a short period of time, and may also have to prepare to resist the Liaodong reinforcements, and the pressure they face can be imagined, what they can do is to destroy the enemy and reduce the pressure on the emperor.

"The Jin army must retreat after the former army mutiny, but the Jin army has always used iron cavalry to open the way and use infantry to rear. As soon as they turned around, they became the infantry army as the front army, but the cavalry army became the rear of the palace, and the two armies fighting for the road will definitely affect the speed of the march, which can buy us some time! "Yelu Yu can be said to be a real 'three-surnamed family slave', born in the Liao royal family to lead the army to guard one side, angrily rebelled against Liao and surrendered to Jin, and was a supervisor of the army, and now he is a vassal of the Great Song Dynasty, but because of this, he is familiar with the combat methods of all parties and understands each other's strengths and weaknesses.

"yes, then we still have a chance!" Zhao Yan was also worried that the Jin army had always fought for the initiative on the battlefield with strong mobility, although the difference between the two armies was only a hundred miles, but it was not easy to catch up with them, Yelu Yu's words woke him up, "Order the cavalry hunting brigade to entangle the Jin army to delay their retreat, so that the cavalry of the Lion Wing Army and the cavalry of the Hezhong Army take a shortcut to cut off the Jin Army brigade to the north, and when the Dragon Wing Army arrives, it will annihilate the Jin Army!" ”

"Well, this plan is feasible, but we have lost a chance to make a big difference!" Yelu Yu nodded and said, now the three-way army is cutting gold, and the other two are attacking the city and plundering the land, destroying countless enemies, and recovering Youyan, and they just beat the side drum and give others a hand, which makes people feel a little uncomfortable...
