Although in order to confuse the opponent, the crossing team did not cover up and keep secret this so-called "Overlord Operation Jihua", but carried out recruitment and material transportation in various prefectures and counties with great fanfare, and did enough "publicity" and "rendering" for this operation, so that almost the whole world knew about it. But whether it was out of the usual prudence or the deep fear of the Beiping Army in their hearts, all parties in the Later Zhou court were more concerned about the authenticity of the Beiping Army's action while rejoicing. As a result, everyone is "eight immortals across the sea, each showing their magical powers", mobilizing everything they can mobilize, in order to get a reliable, accurate news.

The first to react to the Beiping Army's Northern Expedition was Zhang Yongde, who considered himself to be ahead of other opponents in intelligence gathering. After learning that the Beiping army intended to conquer the Khitan in the north, Zhang Yongde immediately sent someone to send a secret letter to Zhang Yan in Lu County, ordering her to get in touch with Fan Wucheng immediately, and be sure to find out reliable information about the Beiping army's invasion of Liao from the latter's mouth, and return to the capital as soon as possible. Zhang Yan didn't dare to slack off after receiving the order, so he immediately sent his right-hand man Shi Ran to set off and go to Beiping City to connect with Fan Wucheng and investigate.

Shi Ran asked for a joint, which was something that Fan Wucheng expected. As early as when the enlarged meeting of the committee decided to restart the "Jianye No. 1 Operation Jihua", Fan Wucheng had already been mentally prepared, and thought of a common argument that he would use to shirk the responsibility of providing Zhang Yan with the wrong information in case the people of "Feiyantang" discovered that the Beiping Army's large-scale conscription and preparation for war were going south to the Central Plains. As a result, to Fan Wucheng's surprise, he was both surprised and secretly pleased that in order to cover up the intention of the Beiping Army to actively prepare to go south to the Central Plains and achieve the effect of surprise, the committee actually asked the Military Department, the Intelligence Department, and other relevant departments to carry out a so-called "overlord operation" that attacked the east and the west and concealed the world. In this way, not only did it perfectly prove the "authenticity" of the false news about the next move of the Beiping Army, but also conveyed such a "big road" news, which would not attract the attention of "Dark Feather", let alone make him feel guilty for betraying his brother and betraying his team.

However, as the saying goes, "know what you know and what you do, and you will not be defeated in a hundred battles". While rejoicing and secretly rejoicing, Fan Wucheng did not forget to learn the details of the "Overlord Operation Jihua" from various channels, so that he could better deal with the intelligence pressure from the "Feiyan Tang".

Since the "Overlord Operation Jihua" was formulated by the Committee, the Military Department, the Intelligence Department and other relevant departments, as the head of the Ministry of Commerce and Trade, Fan Wucheng did not have the opportunity to personally participate in the planning of Jihua and obtain detailed information about Jihua. In fact, not only Fan Wucheng, but also other traversers who did not have the opportunity to participate in the formulation of Jihua also did not know the details of Jihua. After all, what they need to do is to seriously implement the "Jianye No. 1 Operation Jihua", and not actively participate in this "Overlord Operation Jihua", which has little to do with them. Therefore, all the information about this jihua before was obtained by Fan Wucheng from listening to rumors and chatting with the brothers who participated in the formulation of jihua. It can be said that in terms of understanding of "Operation Overlord Jihua", Fan Wucheng is actually not much more than Zhang Yan. Therefore, in order to obtain more information, so as not to fall behind in the confrontation with the "Feiyan Tang", Fan Wucheng asked his confidants to inquire about the operation in Beiping City, and at the same time, he also gave orders to Liu Erxing, Gao Gui and others, asking them to use their positions, identities, and connections to find out as much as possible some news related to the "Overlord Operation Jihua".

Because it was the first time that Fan Wucheng had given them instructions since the commission, whether it was Liu Erxing, Gao Gui, or Duan Ming, or Xu Wang and Xu Huan brothers, they all went all out and worked hard, and soon they all sent news to Fan Wucheng. Of course, due to the different positions and departments to which these people belong, there is still a big difference in the reliability and detail of the information that the five people can probe, and the most reliable and detailed of them is none other than the noble.

Although the noble military rank is not high, as the commander of the uniformed battalion who specializes in providing uniform equipment for the "Flying Dragon Army", he has the opportunity to access many secrets of the combat operations of the "Flying Dragon Army". As far as the "Overlord Operation" alone is concerned, the information that Liu Erxing, Duan Ming, and the Xu brothers were able to provide was actually not much different from what Fan Wucheng had before, and there was nothing really groundbreaking, and some people even believed in this operation and asked their families to hoard food and other materials in order to cope with the shortage of materials caused by the protracted war -- although Duan Ming was a deputy commander of the "Security Army," because the Sixth Regiment of the "Security Army" to which he belonged was not in the "Operation Overlord Jihua" , so he didn't get more news than others, so that the bits and pieces of content that Liu Erxing got from Liu Xiaoliu were more valuable than his. But he is noble, but because of his position, coupled with his connections in the "Flying Dragon Army", he not only knows very well that the so-called "Overlord Operation Jihua" is far from being as huge as rumored by the outside world, but also knows that this Jihua is by no means just a deceptive gimmick and a smokescreen to confuse the opponent, but a complex jihua that mixes truth and falsehood, fiction and reality, and is a mixture of truth and falsehood.

What is even more rare is that through the analysis of the number of summer clothes that the "Flying Dragon Army" commanded the battalion to prepare summer clothes and the place and time where the relevant clothing materials needed to arrive, plus the news that he managed to inquire from many of his former subordinates, he speculated that the Beiping Army might be used for the strength of the Khitan Zhongjing Province and the time and place of the attack, and put forward countermeasures that he thought were feasible -- at the end of June of the eighth year of Xiande, Qian Yuanshan was the commander-in-chief of the Northern Expedition, with 10,000 to 12,000 army troops, and went out from Shanhaiguan. Attack all the way north along the coastline, possibly as far as Jinzhou. The Navy and Marine Corps will cooperate with Army operations to ensure logistical supply and the security of the Army's flanks and rear flanks. If we want to strike at the Beiping army that has left the city, the only way to do this is to lay heavy troops around the Yongle City in Jinzhou, and take advantage of the favorable situation that the city is far from the coast and the Beiping army and navy cannot provide effective fire support and flank cover for the army, so as to inflict certain casualties on the Beiping army besieging the city, and try to cut off its logistical supply line to force it to abandon its attempt to capture Jinzhou.

Of course, the purpose of this countermeasure was to force back the Northern Expeditionary Force of the Beiping Army, not to completely defeat it. After all, no matter how noble he did not want Qian Yuanshan to make new contributions, he could not deny or change the gap in strength between the Beiping Army and the Khitan Army, let alone hope that the Khitan Army would be able to completely annihilate or defeat at least the Beiping Army's Northern Expeditionary Force, including at least two regimental-level combat units of the "Flying Dragon Army" Army and a team combat unit of the Marine Corps -- even if the Khitans had the detailed combat of the Beiping Army's Northern Expedition, nothing would change.

Receiving this information provided by Gao Gui, Fan Wucheng was both happy and surprised. Happily, this noble information is not only detailed, but also extremely reliable, and it is more than enough to deal with the "Feiyan Hall". What is surprising is that this "overlord operation jihua" is actually planned so complicatedly, completely beyond his previous estimate that this jihua is purely used to confuse the smokescreen of all parties in the Later Zhou court, but the truth is false, and the truth is in the false, which not only misleads the parties in the Later Zhou court, but also effectively hits the strength of the Khitan, killing two birds with one stone.

This is the essence of this "overlord operation", and it is also the main content of Wang Kunjun's revision opinions after seeing the original jihua submitted earlier by the Ministry of Military Affairs that used pure false actions and intelligence as a means to confuse all parties in the Later Zhou court and cover up the true intentions of the Beiping Army. In Wang Kunjun's view, a successful "Overlord Operation" similar to the Allied army's deception of Nazi Germany and the disguise of its real landing in France in the previous life can effectively confuse all parties in the Later Zhou court and create favorable conditions for the Beiping army to move south to the Central Plains. However, after the shrewdness of all parties in the Zhou court, there is no absolute certainty of success in whether a pure false action can really confuse the other party. Once it is recognized by all parties in the Later Zhou court, then the Beiping army will not only waste its energy, but also become the laughing stock of the other party. Second, even if the relevant deception actions are very successful, although they can confuse all parties in the Later Zhou court, they will also confuse the Khitans. And the Khitans, after believing it, are likely to gather forces to fight against the non-existent Northern Expeditionary Army in order to protect themselves. Once the Khitans found that there was no strong enemy attacking, and the direction of the Beiping army was the direction of the Later Zhou court, which had already been in turmoil. Then it is possible for him to breathe a sigh of relief and collect his troops to recuperate. It is more likely that they will attack the Beiping Army south because they feel that there is an opportunity, which will bring unnecessary trouble to the Beiping Army whose attention has shifted southward. Therefore, instead of spending a lot of resources to set up a pure illusion, it is better to adopt a strategy of mixing the real with the false, and the virtual with the real. While confusing all parties in the Later Zhou court, he really sent an appropriate number of troops out of the fortress to carry out a limited attack on the prefecture and county towns of the Khitan Zhongjing Road, attracting the main force of the Khitan army to come to the aid and inflicting heavy losses on it. Therefore, before the main force of the Beiping Army went south to the Central Plains, the Khitans were taught a hard lesson, so that even if they wanted to make trouble for the Beiping Army to chase the Central Plains, they would be powerless.

Wang Kunjun's proposal was unanimously approved by the committee, the military department, and the intelligence department. Therefore, when the "Overlord Operation Jihua" began to be put into practice, in addition to the false intelligence propaganda and public opinion exaggerated to confuse all parties in the Later Zhou court, there was also a real force composed of the third regiment of the first synthetic infantry division of the "Flying Dragon Army", the "rangers" battalion, the "wolf tooth" battalion, the independent cavalry regiment, the first independent artillery regiment, the "security army" independent cavalry regiment, the first regiment of the marines, and more than 200 warships and transport ships of the first fleet of the navy. A total of more than 30,000 people (including 12,000 army troops) of the Northern Expedition. This army was led by Qian Yuanshan, Huanghai (in charge of Liliang on the sea) and Zeng Zhilin, and their offensive route was just as Gao Gui expected, from Shanhaiguan to the coastline, from Runzhou, Qianzhou, and Laizhou in the Khitan Zhongjing Road, to Xizhou. In the end, the troops came to the city of Jinzhou and induced the Khitans to send heavy reinforcements to achieve the strategic goal of annihilating the opponent's life, hitting the morale of the opponent's army, and eliminating the worries of the Beiping army going south.
