While Xu Sheng was discussing how to attract Cao's army, Liu Lan was also concerned about the war in Pei County, although he failed to give Pei County the most favorable guarantee and could not reinforce more troops, but a lot of news came to Liu Lan breathed a sigh of relief.

Among the gathered intelligence, the most attractive one for him was that Yuan Tan of Donglai led the main force to Chengyang County to join Yan Liang, this situation is a bit delicate, although Liu Lan can't determine whether this convergence is aimed at Xuzhou, but from the distribution of Yuan Shaojun, such a convergence, there is a real need to use troops against Xuzhou, especially in the case of Peixian County, where there is already a fierce battle, the possibility of Yuan Shao coming to Xuzhou to fish in troubled waters has become very great.

In this way, their temporarily changed deployment became extremely important, because Xu Shu had already issued a deployment to deal with the Jizhou army, and now the most important thing he had to consider naturally changed from Peixian to Langya.

Langya is next to Chengyang County, and Dongguan is adjacent to the Lingling, but because Dongguan does not have any troops deployed, if a war with Yan Liang is serious, the situation is likely to become a two-sided attack by the Jizhou army, so it must be arranged as necessary, just in case.

But there is one point that Xu Shu also analyzed, that is, the enthusiasm for Xuzhou is not high, so there is no need to have too many troops for defense and matching, and the most important thing is Yan Liang and Yuan Tan from Chengyang County in the east.

And Liu Lan's idea is to gather troops in Yangdu, this is the place to go south to Kaiyang, whether it is Yan Liang, Yuan Tan or the trial from Dongguan to the south, as long as the south invades Langya and attacks Kaecheng, it is bound to attack Yangdu County, so as long as Yangdu is held, it is equivalent to holding Langya and losing Yangdu, then Langya County has little hope of holding it.

But for the defense of Yangdu County, there has been a lot of controversy, because Yangdu County is a small county, the population is small, the city is low, if it is based on the city and defended, then he does not have many advantages, but it is better to retreat to the south of Linyi County, only more than 120 miles, although it is only a middle county, but it has always had the Kaiyang Acropolis, the city is high and deep, there is a certain advantage for defense, and it is relatively close to Kaiyang, it is easy to advance and retreat, and it is convenient to echo from the north and south, and it is easier to form a horn.

However, there are advantages to being close to Kaiyang, and there are naturally disadvantages, if you go all out to defend in Linyi, then if Yan Liangjun bypasses Linyi and goes straight to Kaiyang, then Kaiyang will be dangerous, if you send half of the troops, then in the face of the main force of the Yuan army, it will seem to be lonely, especially for the division of troops Liu Lan is extremely opposed and even difficult to accept, so although Linyi is more than a hundred miles away from Yangdu, but in his heart he is more inclined to Yangdu.

His meaning is very clear, since Guan Yu's Setshan battalion has been transferred, then in the battle with the Yuan army, we must not only consider how to defend against the Yuan army, but how to take the initiative to attack, then we must not look forward and backward, and want to defeat the Yuan army and want to keep Kaiyang, so this battle, either simply pull the troops out directly, and have a large-scale encounter with the Yuan army in Yangdu, as for Yangdu, Linyi and Kaicheng, they can all be ignored.

For Liu Lan's bold idea, Xu Shu thought about it very seriously, in fact, in the current situation, especially after the cession of Qingzhou, it is too much to consider the gains and losses of one city and one place, and to fight with Yuan Shaojun, if from the beginning, according to Liu Lan's ideas, to avoid the enemy's edge, then no matter where Yan Liang attacks, as long as a small number of troops are left, leave him alone, whether it is to the south or to the east, you can let him feel like no one, as long as you concentrate and go all out to deal with Cao Cao.

But since Xu Shu has persuaded Liu Lan, then Dongguan can give up strategically, and a Langya actually has nothing to give up, so gathering an army in Yangdu, and even taking the initiative at a critical moment will obviously become the real winner of the battle of Xuzhou.

In this battle, as Xu Shu said, let us concentrate our forces, destroy Yuan Shao first, and deter Cao Cao, so as to seek the final victory in the battle of Xuzhou.

Xu Shu stared at the map next to Liu Lan.

The sand table that Liu Lan made in Xuzhou includes Kaiyang, including the entire Xuzhou and even Yuzhou, but there is no Linyi and Yangdu and Qingzhou in the north of Kaiyang, so at this moment the two can only stare at the map, but the new sand table is under construction, and it will not take three days for Xu Chu to do a good job for him, and at that time the two will have a more intuitive understanding of Linyi and Yang.

At this moment, the two can only judge by the map, and if the war starts in Yangdu, then the movement of the troops is particularly important, especially when Guan Yu has not yet arrived in Xuzhou, Huang Zhong's Langya army can not be moved too early, nor too late, it is best to let Guan Yu's Setshan battalion play the role of a surprise soldier, and then a blow can repel the Yuan army and drive them directly back to Linzi.

But Xu Shu had a different idea, he felt that in the battle with the Jizhou army, the enemy's strength was not less than theirs, on paper, the two armies should be said to be Qihu equal, and the decisive battle was particularly risky, because no one could predict who would achieve the final victory, and from the map, if the two armies were on the same starting line, then the biggest disadvantage of the Yuan army over them was that their battle line was too long.

Although it seems that Qingzhou is now in the hands of Yuan Shao, and Yuan Tan is still the thorn history of Qingzhou, don't forget that they have only been in charge of Qingzhou for a few months, and the people's hearts have not been attached, so they raise grain and grass, although they can raise some from Qingzhou, but more still need to be raised from behind Jizhou.

And this situation is actually exactly the same as the battle of Jizhou that year, and Yuan Shao had done his best in the battle of Jizhou back then, in Liu Lan's words, the two sides should have been a draw, and even Gongsun Chan was defeated, and Yuan Shao won completely because he found Gongsun Zhan's land for grain storage, and he had destroyed Gongsun Zhan's grain route in the river.

Therefore, in this battle, they can completely follow the example of Yuan Shao at that time, as long as they can find the enemy's grain storage point, and then cut off the grain route from Jizhou, then Yan Liang can't retreat if he wants to.

And Yan Liang is now concentrating Jizhou's troops on the border, and there is almost no fortification in the rear, as long as we are willing, we can send a surprise army to recover the lost territory in Qingzhou at any time, and if this candidate is Zang Ba, with their experience in operating in Qingzhou for many years, the soldiers must have opened the door to surrender one after another, and it will not cost a single soldier to recover Qingzhou, and then how much power Yan Liang's troops can have to fight with our army, I am afraid that they will have been in a hurry to recover the lost territory, so as not to be cut off by our army.

Liu Lan was silent, Xu Shu's strategy You can say that he is learning from the plan that Tian Feng arranged for Yuan Shao back then, maybe Xu Shu's arrangement is not as thoughtful and impeccable as Tian Feng, but there is one thing, Xu Shu will not repeat Tian Feng's mistakes, because Yan Liangjun is missing Zhao Yun, the winner and loser.

In the battle of Jizhou, the reason why they were able to win was entirely because of Zhao Yun alone, and he almost single-handedly ensured the smooth flow of Jizhou's grain routes. And the most critical thing, as Xu Shu said, the most critical point of their battle is that the open jaw during the battle of Jizhou is dispensable, because they don't need to find a place for Longcuo to store grain, as long as Zang Ba is sent out, Yan Liang will definitely be in turmoil, and when the time comes, as long as he is out of array and withdraws back to Qingzhou, then they can attack back and forth, or eliminate or defeat, all by personal will.

At that time, let alone defeat Yan Liang, even if it is impossible to completely recover Qingzhou, it is even more desperate, simply destroy all the ferries of the Jizhou Army on the Yellow River, and completely cut off Yan Liang's back road, at that time, as long as they slow down the pace of attack, it is not impossible to wipe out Yan Liang in Qingzhou, and the most important thing is that there is no need to worry about Yuan Shu's counterattack, so that the battle of Xuzhou will establish Liu Lan's position as the largest force in the Kwantung region in one fell swoop.

However, this is not very likely, whether it is Yan Liang or Yuan Shao, they will not have any protection for the ferry, and it is not very likely that they want to sneak attack the ferry, but if it is implemented according to Xu Shu's plan, only Beihai County needs to be taken, then Yan Liang's army will definitely be disrupted, and this is enough.

At this time, Xu Chu reported loudly outside the conference hall, saying: "Lord Qi, there is a flying pigeon in Pei County to send an urgent message."

"Bring it in." Liu Lan hurriedly responded.

After Xu Shu entered the house, he presented the letterhead to Liu Lan with both hands, Liu Lan took the small letterhead, poured out a note from it, the note was silk paper, which was rolled into a long circle and unfolded the note, and there was nothing on it, just let him tell Zhao Yun something and keep an eye on Cao Cao.

Liu Lan was not surprised by Xu Sheng's worries, after all, these circumstances were all within his expectations, after all, Cao Cao claimed to have led more than 200,000 main forces to attack Pei County, although there must be water in it, but the alliance between him and the Shouchun army, no matter how small the number of troops, would never be less than 100,000, such a huge force, it was easy to deal with the defenders of Zhao Yun and Xu Sheng combined with less than 50,000 people.

Xu Sheng's worries were not unreasonable, but what Liu Lan was most afraid of was that Cao Cao might attack Peixian with all his might, and at the same time, he might also attack other places by surprise.

One of the four counties of Xiapi, Donghai, Langya and Dongguan.

Remind Zhao Yun that this matter is very simple and very easy to do, the meaning of the battle of Peixian, they are to drag Cao Cao, and Cao Cao wants to attract his main force to Peixian or to besiege the city for reinforcements or simply to storm Peixian, as time goes by, Cao Cao's intentions will be revealed, as for how to deal with it, Zhao Yun and Xu Sheng will make a reasonable choice.

And he must now find another direction in which Cao Cao might send troops.

Don't doubt that Cao Cao doesn't plan to divide his troops, with his understanding of Cao Cao, if he really wanted to attack Peixian, he would have attacked a long time ago, and he wouldn't send Dian Wei to call the battle, which is a strange thing in itself.

The existence of Dian Wei, or the existence of Xu Chu, is that Liu Lan imitated Cao Cao's arrangement of Dian Wei, he is a personal guard, what is his duty, Liu Lan knows, Cao Cao also understands that using such a person to provoke is itself a fight for the sake of fighting generals, which is completely unreasonable.

Therefore, Cao Cao's move is **, and it is Lu Yi who is besieging the city to help, and his purpose is to tell Xu Sheng and even himself that he Cao Cao himself is now in Pei County, he wants to capture Pei County, and the next step is to attack Xuzhou City.

Xu Shu, who took the note from Liu Lan in the morning, read the content of the ten words in the letter, and said softly: "Cao Cao used himself as bait? ”

"Hmm." Liu Lan said, came to the sand table with his hands in his hand, looked at the direction of Pei County in the sand table for a few seconds, moved the flag marking Cao Cao from Fei County to Pei County, and said: "Our old opponent is very difficult, I thought that he would only send Xiahou Dun or even Cao Ren to bring troops over, and he would personally lead the surprise soldiers to raid Xuzhou, it seems that I still underestimated Cao Cao." ”

"The lord said that Cao Cao used soldiers, combined with Zhengqi, eclectic, and it was possible to make any kind of decision." Xu Shu felt that Liu Lan did not need to be too entangled in this matter, in fact, from the very beginning, Xu Shu always thought that Cao Cao would personally lead troops to Pei County, but Liu Lan felt that it would not, because Cao Cao used troops, where he was, where was the direction of Cao Jun's main attack, and now Cao Cao was in Pei County, it seemed that Pei County was the direction of Cao Jun's main attack, but Liu Lan firmly believed that the truth was not so.

Don't doubt that Cao Cao doesn't plan to divide his troops, with his understanding of Cao Cao, if he really wanted to attack Peixian, he would have attacked a long time ago, and he wouldn't send Dian Wei to call the battle, which is a strange thing in itself.

The existence of Dian Wei, or the existence of Xu Chu, is that Liu Lan imitated Cao Cao's arrangement of Dian Wei, he is a personal guard, what is his duty, Liu Lan knows, Cao Cao also understands that using such a person to provoke is itself a fight for the sake of fighting generals, which is completely unreasonable.

Therefore, Cao Cao's move is **, and it is Lu Yi who is besieging the city to help, and his purpose is to tell Xu Sheng and even himself that he Cao Cao himself is now in Pei County, he wants to capture Pei County, and the next step is to attack Xuzhou City.
