Yanbei did not have a clear understanding of Cao Cao's current situation, although his staff were all talented people in the world, but in the end, few of them were from Yuzhou, and even the people of Yanzhou were pitiful, so he did not know enough about the situation in Yanzhou and Yuzhou, but took it for granted that the two states controlled by Cao Cao were compared to places like Youji.

This is a great fallacy.

Although Yanyu and Youji are both two states, the gap between these four states is not small. First of all, there are few feudal states in the north, and even if there are, they are some royal side branches, and their ability to control the land is extremely weak. But the identity of the Wuhuan subject country after the Yan clan became big in the past ten years has always been in the position of contributing taxes to the north.

Wuhuan does not hand over the mouth to calculate the endowment, but to pay the destiny. Wuhuan Shan Yu from the old single in Qiu Liju, Dai Shan in Badun, new single in Lou Ban, after three terms. But in the past ten years, the Yan clan has spread from a corner of Liaodong County to the north and planted Yanzi flags, and in every military conflict and every huge battle, Wuhuan warriors will always be the strongest backing in Yanbei.

Although they have never made great achievements and achieved the unparalleled prestige of the Yan clan's war generals, it is undeniable that hundreds of thousands of Wuhuan men have walked out of the subject country, and fifty percent of them have buried their bones along the edge of the land ruled by the Yan clan. There is such a saying about Yanbei in the subject country of Wuhuan: from the east to the single leader, to the south of the riverbank, to the west to the south of Longguan, and to the north of Jundu Mountain. Ask King Zhao what battles he fought, and he only needs to look for the Wuhuan tombs all over the mountains.

Yanbei has absolute dominance over the north, and the only one who can be compared with Yanbei in this point is Jiaozhou Shixie.

But Cao Cao did not have such a ruling power, because there were so many princes and kings surnamed Liu who did not pay taxes in the land he ruled, resulting in the land he actually controlled not as much as across the two states, which made it difficult for Cao Cao to be with the Cao Mengdebai imagined by Yanbei in terms of grain, grass and money.

But Cao Cao is not bad, he has money, in the past, in addition to encouraging the people to farm, the means of raising grain and grass in the past were to buy grain and grass from the princes and kings in various places, and now the situation is actually better for him, because the princes and kings are gone, as long as he can recover those lands, he can really hold the two states to open up the situation...... The premise is to beat Yanbei within three months.

Otherwise, everything will be over.

Guo Jia could guess that Cao Cao didn't have much military rations left, but he couldn't guess how much was left, and under Guo Jia's estimates, Cao should have at least six months of military rations, and no more than a year at most. This is a good thing for the Yan clan, and if the war continues to drag on, it will only be beneficial to the Yan clan, because the war broke out in the territory controlled by Cao Yuan and the others.

"In terms of grain and grass alone, the supply of grain to Yandi, the road consumption is huge, and the people in the state will inevitably mourn all over the country next year; However, there is no major drought in Jizhou this year, and as long as we persist until the grain harvest is large, all problems will be solved. Guo Jia said with a smile: "In the next suggestion, the general should avoid the war, defend Dongjun and Chenliu, increase troops to Shanyang County to protect General Zhang's retreat, and hold on for half a year, and the Cao clan will be defeated." ”

The Yan family has a great problem in grain and grass, and the cost of grain and grass transportation from Youzhou to the south bank of the Yellow River is as high as 70%, even if there are donkeys and horses, this number can only be reduced by 10%, which is equivalent to transporting 100 stone of grain to Yanzhou and only 40 stone left. This is also because of the reduction of road consumption by sea and land transportation, otherwise by land transportation alone, there will only be ten stone of grain left in Yanzhou, which will not be able to supply the army for consumption. Fortunately, the Yan clan has occupied most of Yanzhou, and the supply of soldiers and horses from all walks of life can be fed and the enemy, otherwise the pressure on the north will also be great.

"Fortune is mine." Yan Bei nodded and smiled at Guo Jia: "If it weren't for the rain and snow last year, if there is another year of drought this year, Yan can only withdraw from the army in August." ”

The eight-month war made Qingzhou and Yanzhou scorched earth, Qingzhou was still good, and the Luyi Department took three counties to confront the Yuan clan as soon as they came up, which had little impact on the people. Before the Yanzhou War, Zhang Liao walked and retreated, and the Yan army came to get grain and grass supply, and the Cao army came and the people had to take grain and grass supply, and the people had no food so they could only abandon the land and take refuge in other places, but there was nowhere to go.

There is a big river in the north to block it, and the boats along the way are all requisitioned by the Yan army, in order to prevent Cao Jun's secret agents from blocking the river and prohibiting the passage of civilian boats; In the east, the war in Qingzhou is in full swing, and the transportation arteries are blocked; Although there was no one to block the main roads to the south and west, they were all caught in the war and could not pass through at all.

Sixty percent of the people in northern Yanzhou have taken refuge in the nearby mountains to eat in the wilderness in order to save their lives. The rest are all families with many families, and they cultivate diligently in order to survive.

"Shift the defensive?" Yanbei did not agree with this, he had an absolute advantage, and the foundation of the north was unstable, and he urgently needed a big victory to deter the north. This is his usual means of maintaining his rule, and he is extremely skillful. Emperor Fengying then attacked Goguryeo Buyeo, and the court discussed that he would crusade against the Southern Xiongnu to stabilize and merge the state, and proclaim his military might. This time is no exception, Yanbei also wants to break Cao Cao to deter the court and the royal gate, "Now that the army has been sent, how to defend the so-called defensive position of Fengxiao?" ”

This kind of thing is like a treasure for Guo Jia, and he said: "The Cao army is on guard, and the scouts of the former army have reported to Cao Ren, who is stationed in Jiyin County and the second city of the single father, and Yu Ban is camping in the mountains between Chengwu and blocking our passage to the south. After Liu Chong's death, Chen Xiang Luo Jun joined forces with the Cao clan, and they were well supplied with soldiers. As the king said, the fortune is in me, instead of taking advantage of the battle with Cao's army, it is better to delay the decisive battle time as much as possible and force the Cao clan to fight a decisive battle with me. ”

Guo Jia's words were very level, forcing the Cao family to fight a decisive battle with them, and a decisive battle with the Cao family, but the difference between the two words revealed a different meaning.

"Do you mean to send a partial division to fight against Cao Ren and block his chance to go north?" However, a few words led to a huge strategy in Yanbei's heart, "To the west, Chen Liu, Yingchuan and Sizhou soldiers and horses will join forces, and to the east and Lu Yi will unite to oppress Zang Ba, and Cao Ren will be prevented in the middle but will not fight with him, when the Cao clan is urgent and urgent to fight with me because of the urgency of food and grass, the whole line will break through the defense lines everywhere, and collect Yanqing, and break Cao Cao in one fell swoop?" ”

Guo Jia nodded and said, "That's exactly what I mean!" ”

"With Gao Lan and Zhang Jaw as the partial divisions of the West Road, each leading the headquarters to march to Chenliu and collect Yingchuan to the south can be cheap. Yan sat on the Chinese army to garrison Cao Ren, and the east road was led by Wuhuan Wang Badun and Yan Rou, and let them help Zhang Liao all the way. Yan Bei raised his head as he said and asked, "Where has General Zhang's recent battle report gone?" ”

"Back to the king, General Zhang has entered Peiguo three days ago." Guo Jia smiled and covered his hands and said: "I will arrive in Qiao County in a few days, Pei Guo Qiao County!" ”
