From late June to mid-July, the entire Guandu was under construction, and the soldiers, auxiliaries, and civilians on both sides basically spent this summer in civil engineering and scattered battles!

The first to make a move was naturally Gongsun Xun, who immediately mobilized Sizhou soldiers and horses after discovering that Cao Cao's strategic contraction and the confrontation at Guandu was inevitable, and in order to resist the opponent's permanent fortifications, he adopted Cheng Pu's strategy, that is, the company battalion moved forward, trying to directly approach the opponent's camp.

However, this strategy in turn made Cao Cao wake up, and his people immediately started a large-scale construction, on the basis of the original four front battalions, they started the company camp to fight the company camp!

However, it is also a company battalion, but there is an unusually significant difference between the two...... The company battalion of the Yan army was the north and south company battalions, and the goal was to spread the fortifications in front of the opponent's battalion, so as to attack the Cao army's battalion on the basis of erasing the difference in fortifications, which was vertical; However, Cao Cao's company camp is the left and right company camps, and his camp is constantly extending to the left and right, as if there is a tendency to build a simplified version of the Great Wall in Guandu, which is horizontal!

To be sure, this was a stroke of genius, because this kind of company camp could greatly reduce the tactical movement space of the Hebei cavalry in the Guandu area...... It is even said that if Cao Mengde really makes a complete blockade of the inner Great Wall in the Guandu area, it is really possible, and it is extremely cost-effective!

Because this can completely cut off the cavalry advantage of the Yan army, and then liberate the reserve forces used to defend the cavalry in several cities behind the Cao army!

Think about it, isn't it a distance of dozens of miles wide from the mountainous area in the west to the Bianshui in the east? The Great Wall can be repaired, but a simple long-term camp can't be repaired? In this situation, is Cao Cao not having manpower and material resources, or Gongsun Xun not having manpower and material resources?

In fact, after Cao Mengde came to his senses, he kept mobilizing and organizing the people to repair the camp, and at the same time, he kept laying a kind of simple cavalry defense line on the passage on both wings, mainly wooden fences, horse rejections, and watchtowers...... The main battles broke out at these construction sites, as well as further afield in the woods, mountains, sand piles, and other areas where the construction materials were produced.

Within dozens of days, various sporadic battles broke out everywhere, and the two sides came and went, and the fighting was trivial but frequent.

The officers, non-commissioned officers, and civilians below will naturally be anxious because of this kind of fortification confrontation, but for the commanders of both sides, they may not care about these details.

In fact, these confrontations and the progress of fortifications, from Gongsun Xun's point of view, only show one thing, that is, Cao Cao did not lose his temper because of the previous battle, but reinvigorated.

That's all.

And these days, Gongsun Xun's mind is not on Guandu, but on three things outside the Guandu battlefield:

First, which battlefield should the remaining Kansai soldiers be put into? Is it to go directly out of Wuguan, and then let Zhao Yun go east from Hanzhong and follow the Han River, and join forces to attack Nanyang? Or go out of Luhun Pass and march into Rushui and try to dig out the back road of Yingchuan? And simply took it to Guandu, or even handed it over to Lou Gui?

Second, do you want to add weight to Guan Yu? If so, how big should you add? When to increase the size? After all, Zhou Gongjin must be twelve points careful, although Guo Jia was sent, Gongsun Xun was still a little apprehensive.

Third, how to deal with the letters in Nanyang, Yingchuan, and even Nanjun...... That's right, after the First World War in Guandu, the surrender faction in the Central Plains began to emerge in large numbers!

In fact, if you think about it, before the first battle of Guandu, although Hebei looked stronger, in terms of paper strength, Cao Cao, who was supported by Liu Biao, Liu Bei, Sun Ce, Lu Bu, and Xiao Tianzi, did not seem to be worse than Gongsun Xun. And the power on paper is precisely the basis for the judgment of these wall-stickers, or capitulationists.

However, the impact of the Battle of Guandu was absolutely far-reaching, because the encounter was so fierce and straightforward, so the outcome and significance of the battle went far beyond the battlefield itself...... First of all, it proves that Gongsun Xun's Hebei army or Yan army is indeed as strong as it is rumored; Secondly, it proves that Gongsun Xun and Yan Jun, who are in the ascendancy, have not fallen into arrogance, and now this Yan Gong is still the Wei general of the year, and now this Yan army is still the strong army in the north that swept half of the world!

And if the stronger side is still the more daring and capable side, then the direction of the war seems to be clearer.

In addition, Cao Cao took the initiative to give up the depth of nearly two hundred miles, which made the hinterland of the Central Plains, such as Yingchuan, Nanyang, Chenjun, and Liangguo, directly exposed to Gongsun Xun's soldiers, which naturally shocked those wall grasses even more.

In fact, at the same time that the two armies were building a large camp in the Guandu competition, these days, not only Gongsun Xun had obtained a lot of messy letters here, but also Cao Cao had broken out several rebellions behind him that tried to echo Gongsun Xun...... The scale is not large, and the people who make trouble are probably some small heroes and the like, and they are basically pressed down by Sun Ce and Lu Su with a finger.

But there is no doubt that this is a sign and can also evolve into a tactical choice for the Yan army!

In this regard, Gongsun Xun will naturally think about it.

"The minister thought that His Highness was thinking too much." In the big tent of the Chinese army, which has been upgraded to a civil structure, Jia Xu, who was specially called, smiled after reading a few letters. "The letters are indeed correct, and these people do have the desire to change their minds, but they may not be useful in the overall situation......

"What does that mean?" Gongsun Xun was curious for a while, he has always been convinced by Jia Wenhe for this kind of thing in people's hearts, just as he only serves Xun Gongda when there are many opportunities on the battlefield.

"I would like to ask Your Highness, why do you have any doubts about these letters?" Jia Xu reversed the right color.

"I just think that since I never reprimanded the world from the Yang Palace, what I did was nothing more than suppressing the powerful and the world, and the new policies implemented over the years, Dutian, Shiwu, and the imperial examinations, were essentially suppressing them; As for Cao Mengde, although he did not do a bad job, his strength was obviously inferior to mine...... And since these people are grass on the wall, most of them are immoral and selfish people, and shouldn't selfish people regard me as an enemy between me and Cao Mengde? Why are they preparing to take refuge in me? Gongsun Xun's gaze swept over the busy staff in the wide military tent, but it was rare to be sincere.

"That's why Your Highness thinks too much." Jia Xu laughed again. "Or being in a high position, I can't help but be suspicious...... In fact, please think about it the other way, since these people have done something to betray the Lord, then as His Highness just said, most of them are immoral and selfish people, but the people who are immoral and selfish are often people without foresight, and this kind of person is destined to only see the immediate interests and harms, how can they have the ability to see through the system? So in their eyes, they will only hate Cao Mengde because Cao Mengde has done it to them, but they will not hate the lord because he has done more thoroughly in Hebei, because the lord is in Hebei, but he has not been able to spend these fields in the Central Plains! ”

Gongsun Xun was in a trance for a while: "In this way, I got the tip of the horns." However, I also know why Wen He said that they are useless, this kind of person has neither vision nor virtue, and when he sees weakness, he rises when he sees it, and when he is strong, he destroys, how can he rely on it in war? But Wenhe, if these vulgar and rampant people are destined to be incompetent, who is the ultimate obstacle to my new policy? You must know that in my life, now there are nothing more than two careful thoughts, one is to re-settle the four seas and make the world one; One is to set a new system, a new strategy, to replace the old system of the Qin and Han dynasties, not counting on thousands of generations, but it can also withstand the erosion of two or three hundred years...... That's all. ”

Jia Xu twisted his beard and smiled, but he was speechless.

Gongsun Xun woke up for a moment and laughed along.

After the two of them finished laughing, Gongsun Xun waved his hand and asked a few people who had already listened to the stupidity next to him to come over: "Find a messenger and send all these letters to Cao Cao......"

A few people had just bowed their heads and were about to step forward to pick up the letters on a few cases, but Gongsun Xun temporarily changed the order: "Forget it, you can discern if there are any people involved with the generals in the Cao Army, keep it a little, and take out the rest and burn it!" In the future, all such letters will be disposed of in this way, except by those who are particularly important. ”

Led by Wang Ling, who had just been able to move, several names bowed their heads again and said yes, and then went out of the account with this pile of letters to dispose of it.

Gongsun Xun and Jia Xu watched these people go out together, and they didn't say anything for a long time.

"Actually, His Highness's question today and his previous doubts about Kansai and Qingzhou are both the same thing in the minister's opinion." After a long time, Jia Wen and Fang spoke again. "His Royal Highness saw that Cao Mengde was mourning in Guandu, and he was determined to fight in a daze, and he knew in his heart that it would be difficult to make progress in Guandu in a short period of time, so he had the idea of opening up a new battlefield."

"Not bad." Gongsun Xun is also honest. "Wen He Yiyi, I saw that the situation of the two sides was really troublesome, and there was no flaw, so I was helpless for a while...... Without concealing it, I can think of how the next battle will be fought, which is nothing more than arrow towers, earth mountains, artillery, and tunnels...... It takes time and effort, but it is difficult to achieve great results! ”

Jia Xu smiled again when he heard this: "Before, the lord also asked Gongda about the direction of the wind, don't you still want to attack with fire?" ”

"Yes!" Gongsun Xun is still honest. "But I'm also a soldier for many years, and I woke up immediately after asking...... As long as the camp is strictly managed, the gap is opened, away from trees and mountains, a well in a hundred steps, and a water urn in ten steps, whether the enemy is good, I will not care, where will there be an opportunity for fire attack? In the final analysis, this kind of strategy can only be achieved when one party slacks off, but when one party slacks off, what strategy cannot be successful? It doesn't matter what kind of fire attack it is. ”

"So my lord!" Jia Wenhe suddenly turned positive. "This is the end of the battle...... The minister is still the previous opinion, the lord is better at fighting than Cao Cao, and Hebei is more confident than the Central Plains, as long as we persist and never slack off, then the first to hold on must be the Southern Army! Why rush? As for whether to open up a new battlefield, the minister thinks that the lord should not be too anxious, but should take advantage of the situation, and wait until there are flaws on the eastern or western fronts, or even Guandu himself, before making a decision! Instead of forcibly throwing soldiers and horses into Cao Jun when he has the spirit of mourning, there will be a risk of frustration at that time!"

"I already understand what Wenhe means!" Gongsun Xun sighed. "You want me to guard against arrogance and rashness, and wait quietly for the warplane, right? Don't worry, since Wen He has analyzed it so thoroughly for me, I won't rush it anymore...... Otherwise, the war will be frustrated, but my two small ambitions will never be allowed to fail here! ”

Jia Xu stood up and saluted and said yes.

And since the two monarchs and ministers agreed, they didn't say much, but went to their own work...... Jia Wenhe, as one of the two military divisions accompanying the army, is equivalent to Gongsun Xun's deputy second, and also has his own job and small battalion, so he naturally wants to leave. And when he walked out of the door, he saw that the two Chinese army big tent miscellaneous officers who were in charge of burning letters were the Qianshi Sima and his brother-in-law of the Southern Army who had defected from the battle before, but they smiled slightly, and went away with their own hands.

However, as the so-called world is unpredictable, just when Gongsun Xun has been persuaded by Jia Xu to make up his mind to calm down and take advantage of the situation, and wait for the Central Plains Coalition Army to reveal its flaws, some things have begun to brew in the easternmost part of the battle line that stretches for thousands of miles, and will make waves.

"Gong Jin!"

In Zhiyan County, Donghai County, Xuzhou, Jiang Gan, who was standing in front of the door of a mansion here, heard a squeak behind him, and turned around to see the door of the mansion wide open, and then a tall, clean and handsome young scholar walked out, and immediately bowed his hands to each other.

In other words, the person who walked out of the door was a lupine scarf, a wide robe and plain clothes, a face like a crown of jade, and an extremely young face, just like someone's son-in-law. With such a posture, I am afraid that no one can believe that this young Confucian student, who is only twenty-two years old this year, is actually the commander of the Eastern Front of the Southern Army and the head of the naval army jointly designated by Cao Cao and Liu Bei, and is a general at the same level as Xiahoudun, Lu Su, Xun Yu, Sun Ce, Lu Bu and others!

Of course, Jiang Gan must have recognized him, because this person was his childhood friend, and he was a close classmate who slept on a couch many times when he was studying in Huainan.

"Brother Ziyi!"

Zhou Yu first stopped on the steps outside the door, looked at the other party carefully for a long time, and then laughed and said forward, holding a fan outside the door and holding the other party's hands, feeling emotional for a while. "You wrote to me in Kaiyang to ask for help before, and I thought you would never come back after you sent your uncle and aunt to the north!"

"Gong Jin laughed, there is a division between you and me, although I don't dare to follow the example of Zhang Yide and Li Huizhi, the two generals, how to advance and retreat, but the rivers and lakes are far away, why not get drunk and say goodbye?" Jiang Gan was also emotional. "I came here today because my parents have passed Langya, the southern personnel, and I only miss Gongjin, so I came back to reminisce about the past...... You can rest assured, this trip is really not for business...... You told me the truth, just now you stood in front of the door, silent for a long time, didn't you think I was here to be a lobbyist? ”

"Neither nor not!" Zhou Yu held the other party's arm, shook his head and laughed. "I can't believe that I can still see Brother Ziyi in this life...... The previous gaffe, and that's exactly why! As the saying goes, Qingqing Zijin, I have my heart, but for the sake of the king, I have been groaning so far! Brother Ziyi, do you want me to show you my heart's liver? ”

Jiang Gan also laughed, and the two immediately entered hand in hand.
