On the other hand, after receiving the return of the spies, the father and son of the Guo family of the East Customs finally sorted out a complete "logical chain" after some thinking and discussion:

The loan note and the center point of the letter are all this person named 'Zhou Yan', and this Zhou Yan is the pseudonym of Yan Day, the prince of Youbei; and the Shuangtian Gambling House in Fengjing City is actually the business of this prince who gathers private wealth for himself; and the recipient Huang Li, that is, Lord Gu's concubine Li Niang, was originally a spy sent to Youbei Third Road by a Nankang family named Di Ting, a mercenary organization! Moreover, this 'Huang Li' specializes in serving the big customer of 'Zhou Yan', and has one-on-one contact with him on a single line; at the same time, in order to take advantage of the geographical advantages of the border city without a trace, he married Gu Hui, the prefect of Jincheng, as a concubine to hide his identity on weekdays.

And the death of 'Huang Li' this time is definitely just an "accident": every time she needs to rush to Fengjing, on the day of meeting with the prince, she invites her master Gu Hui to come to the room for a banquet in the name of cooking herself. After that, with the help of medicine and wine, he turned over his own master, and with his extraordinary light skills, he went back and forth between the Fengjing Shuangtian Gambling House and the Jincheng Mansion in one day.

In this way, although it is a bit troublesome, it is still very secure in terms of security.

However, as the days go by, it is inevitable that some chaos will arise due to paralysis and carelessness. Xu is Huang Li made a mistake in which link, and when he returned home one day, he was caught by the sober Lord Gu Hui, and his identity was completely exposed. Gu Hui used this matter to extort a large amount of silver taels from her; This amount is an astronomical amount for the 'Yellow Birds' who have been organized and distributed to the frontier, but the Youbei people, who happened to be in the quagmire of preparing for the war on two fronts recently, took out a large sum of silver taels, and wanted to express their sincerity in cooperation with Di Ting, and asked Di Ting to mediate one or two from it, so as to promote the alliance between Youbei and Nankang, and make a move to return the favor to the other side, and counterattack the Northern Yan Dynasty together on the north and south lines.

Of course, people have weaknesses, and this Huang Li, who has received a large sum of silver, is after all an abandoned son who was sent to the barren land of Youbei from Nankang, a water town in the south of the Yangtze River, by the Di Ting Organization; And now that his identity has been exposed, if he continues to stay in Youbei, he will definitely be threatened by his life; So, this 'Miss Agent' didn't think about it for long, and made up her mind to defect. Of course, in the face of the temptation of life-threatening and a large amount of silver, it was natural for her to make this decision. So she had no choice but to hand over this batch of cash that was inconvenient to carry to the prefect Gu Hui to deal with it on her behalf. After all, she was married for a hundred days overnight, except for some silver tickets, everything else became Gu Hui's money to hide her whereabouts.

And this Lord Gu Huigu, the method of realizing it is also quite simple - he only exchanged this large amount of cash from the Shuangtian Gambling House for a portable Huinan ticket through the black market in Jincheng, and the loss is almost negligible.

Gu Hui has been poor all his life, and now that such a large amount of ill-gotten wealth has been smashed on his head, there is naturally a retaliatory high consumption behavior; And the Huang Li, who had made up his mind to defect to the seclusion, couldn't even escape from the East Customs, so he was directly killed by the killers sent by the Diting Organization to clean up the portal.

There is evidence and logic, and the conclusion that the Guo father and son came to after summarizing all the mysteries gave rise to a sense of relaxation in their hearts. Yes, the sense of accomplishment of 'solving' a huge mystery and getting important information can already make them satisfied.

"Xing'er, tell me, if it is really as we expected, then what will be the fate of the Northern Yan Dynasty?"

Guo Xiao, the Marquis of Pingbei, who had not slept well for two days and two nights, stretched out his two fingers at this time and pinched his eyebrows vigorously, wanting to relieve the fatigue of the past few days.

Guo Xing touched the beard that had just grown under his chin and was still a little prickly, and replied in a heavy tone:

"Although I don't want to say this, but once this happens, then the possibility of the complete destruction of the entire Northern Yan Dynasty is not low at all."

Guo Xiao ignored his son's somewhat "alarmist and rebellious" judgment, still kept kneading his eyebrows, and gently spit out three words:

"Keep talking......"

As soon as these three words came out, Guo Xing was very surprised! Because in the past, every time I uttered such "rebellious words", I would be reprimanded by my father: either I had to be cautious in my words and deeds, or I would educate myself to only talk about battlefield fighting for the sake of the generals, and never talk about state affairs.

But this time, his father, who had been fighting all his life, was no longer as strict and cautious as before, but allowed himself to continue to 'speculate', which shows how serious this situation has become in his old man's heart.

"Hmm...... Whoever suffers knows it. Although he has a narrow land and few people, the production is extremely rich; The Li family in Dongyou Road is the first granary in the world, although due to the cold climate, Dongyou rice can only be ripened once a year; However, because the soil is fertile and sparsely populated, the annual grain yield is definitely not low.

Therefore, today, when the enemy and us are fighting, it seems that our Northern Yan is waving its army north in the posture of swallowing whales, and it has a great momentum of destroying the withered and decaying and moving mountains and reclaiming the sea; But in the past hundred years, the war between the two sides has not been extinguished, but when did we Beiyan people set foot on any inch of land north of the East Customs? Therefore, according to the child, although the two sides seem to have a huge disparity in national strength, if it is really time to meet shirtless, the victory or defeat is actually still five or five......"

Guo Xing took a sip of hot tea when he said this, lowered his head and looked at his toes, and his two fingers were also intertwined and rotated...... This is exactly what he is used to when he thinks.

And Pingbei Hou Guo Xiao listened to his son's opening words, but he was quite surprised: his son, on weekdays, always swaggered through the city with a group of "honor guards" who couldn't fight tough battles. He originally thought that his son was a staunch and undoubted main battle faction, but he didn't expect that now that he opened his mouth, he would say his own accurate judgment of the current situation of friend and foe. It can be seen that this son's perception of the situation is still extremely keen.

"Judging from the results of previous years, if only my Beiyan and Youbei are fighting, then in the absence of accidents, the number of wins and losses will be at most five or five; And the see-saw consumption in front of the Eastern Customs over the years can also illustrate this; However, once someone adds some extra help, then the impact will definitely be very obvious. We recognized this problem before, so in the last two wars, we wanted to pull those Mobei barbarians to be the vanguard...... However, there are never fools in this world, so the effect of the alliance has never been very obvious...... I can also say that before Beiyan has a decisive advantage, the Mobei people will not give us any help at all; The posture of dragging two families with one hand is more in line with their own interests of the Mobei people; Therefore, they will only beat the water dogs with us, but they will never let us drive them forward. ”

Guo Xiao nodded again and again when he heard this, he had never thought that his son, he could have such a high degree of "strategic vision", and he just asked casually, but he didn't expect to really find some advantages of his son. So he nodded again, wanting to continue to take more things out of his son's mouth, so that he could better understand how much of his ability was still hidden.

"Yes, those Mobei people are all 'written allies' who can only share wealth and nobility and cannot share weal and woe, not to mention that in terms of geographical location, Youbei Sanlu is closer to them; After all, Mobei also has a long border territory with our Beiyan. I'm afraid that even Huangkou Xiaoer wants to get it, as long as the three roads in Youbei are destroyed, the next unlucky one must be the Mobei grassland. ”

Guo Xing listened to his father's words and nodded:

"The reason for the cold lips and teeth is not complicated, if I am from Mobei, the current stalemate situation is what I want to see the most. After all, I can receive two gifts at the same time, and I don't have to make any effort, and the longer this situation persists, the better. It can also be said that if anyone wants to stop the war of attrition between Youbei and Beiyan, that is Mobei's biggest enemy. ”

Speaking of which. Guo Xing stopped and thought about it, and his tone was very heavy:

"In today's situation, our Beiyan has become a tiger rider, but as the initiator, this war is already ready to go and has to be launched. Those big men in Yanjing City are still waiting for us to succeed in the first battle and recover the lost land in the north! However, if this time it is still unsuccessful, my father and son may be able to lose the championship and resign, and no matter how bad it is, he can still leave two lives; If once Youbei really forms an alliance with Nankang, plus the Mobei people who are only willing to share the fruits of victory, but are unwilling to contribute, join it, then my Beiyan will face a two-side, or even three-way attack, a final battle to recover Youbei that will inevitably win in the hearts of those civil officials, but it will be fought by my father and son into a battle for the destruction of the country by Beiyan, then at that time, my father and son will definitely die one step ahead of Beiyan, and they will be nailed to the pillar of shame, so that all the men of the Han family will be ashamed, and in the end they will inevitably end up with a stench of ten thousand years! ”

Hearing this, the old marquis Guo Xiao slapped his hand on the handsome case:

"My father and son have nothing to say about sacrificing their lives for the country, but they must not suffer this injustice, and they must not affect the ancestors of the Guo family!"

"Father, I dare to ask you to write a letter to your Majesty detailing the situation, and leave it to Your Majesty to decide how to deal with this matter. In this way, although it is inevitable to bear the infamy of being a scheming man, it is possible to save some face and blood for the Guo family; As for the weight of your Heavenly Blessing Emperor's heart, there is no need to worry; Could it be that you still expect to be ranked among the three princes in the future? ”

Guo Xiao smiled disdainfully, and then waved his hand:

"At the moment, the situation is tense, and these issues are a matter of later story. Maybe tomorrow my father and son will die on the battlefield, even if they are really posthumously crowned as the third prince of my father, what can I do? Xing'er, my father is a little tired, but I can't delay the presentation of His Majesty's feelings; Now go and draw up a movement in the voice of the Father. Remember, be respectful and concise in your words, and try to explain the current situation in as much detail as possible. After writing, it was sent to my father's bedroom, and it was stamped with the handsome seal after I verified and revised. Before midnight tonight, Pegasus must be sent out of the Eastern Customs without delay. ”

Guo Xing just nodded when he heard this, stepped forward to support his father's increasingly thin arm, and the two slowly walked to the main room of Shuai's mansion.
