The three armies did not move the grain and grass first.

When the war is launched, the transportation of military logistics materials is naturally a very key element, so since ancient times, wars can only be passed along the avenue suitable for the advance of chariots and horses, which can be regarded as a normal military expedition road.

In war, it is rarely a way to go over the mountains and mountains, unless it is a surprise attack by simple soldiers or a surprise attack by a surprise soldier, so that the soldier can carry about ten days of dry food with him, and completely abandon the surprise attack and sneak attack of logistics support, but he can not care about the road of marching.

But this kind of war, the risk is also very great, once the surprise attack, sneak attack fails, the soldiers have eaten dry food, then you can only fight hungry, and in the end you may not need the enemy to fight, your army will collapse on its own.

Therefore, if the Cao army wants to attack Nanyang now, it can only pass through the Xianghan Pass on the side of Bowangpo in order to smoothly transport logistics grain and grass materials, and to ensure that the soldiers fighting in front of them can get the supply of grain and grass materials in the rear at any time.

Therefore, this Xianghan Pass Road in Bowangpo has become the only way to attack Nanyang, and it can also be regarded as a gateway to Nanyang County.

However, the environment on this side of Bowangpo has also caused that there are many dangerous terrains formed by undulating hills on this Xianghan Pass Road, which can allow the defenders occupying Bowangpo to block the Xianghan Pass Road with the help of the terrain.

That is to say, whoever occupies Bowangpo can occupy the geographical advantage and block the road through the north and south, so Bowangpo has the military significance of fighting for soldiers.

Now Pang Yan's Xionglu battalion chased Zhang Xiu's army all the way, occupying at least three-quarters of the area of Bowangpo, and found many dangerous places on both sides of the Xianghan Pass of Bowangpo to send troops to garrison.

However, Zhang Xiu's army eventually controlled the last quarter or so of the northern section of Bowangpo in Xianghan Pass, which made it easier for Xiahou Yuan's Cao army to attack Bowangpo.

But if Xiahou Yuan wants to pass through the Xianghan Pass of Bowangpo and enter the valley plain where Wancheng is located, he still needs to start bloody battles with Pang Yan's Xionglu camp in Bowangpo again and again, so as to completely open up this Xianghan Pass Road.

In this way, if Zhang Xiu's army, who was familiar with the terrain of Bowangpo, as a guide, he might be able to provide some marching trails in Bowangpo for the Cao army under Xiahou Yuan's command to help Cao's army attack Bowangpo.

Although there is only one ancient Xianghan Pass road in this Bowangpo, it can allow the logistics and materials of the army to pass smoothly.

However, if there was a guide from someone who was familiar with the terrain of Bowangpo, Xiahou Yuan could naturally send a small force to detour from some small roads to the dangerous terrain where the Xionglu battalion soldiers were stationed, so as to help Xiahou Yuan's frontal attacking army take these dangerous places at the minimum cost.

In this way, the capture of the Xianghan Pass step by step will eventually allow the 20,000 Cao soldiers commanded by Xiahou Yuan to completely open up Bowangpo.

Therefore, although Zhang Xiu lost Wancheng, he still has great use value for Cao's army to attack Nanyang, as long as he can surrender to Cao's army with the remnants of the main force, and can unite with Cao's army to counterattack Wancheng again, Xiahou Yuan will still be happy to accept Zhang Xiu.

Of course, this is also the bait for Jia Xu to let Zhang Xiu deceive Cao Jun to gain trust, and it is also the root cause of Zhang Xiu's plan to carry out the plan to lure the enemy by pretending to lead the way.

However, now Jia Xu's strategy is still only one step of deception, and Zhu Wei is not sure whether Zhang Xiu can deceive Xiahou Yuan's trust, and whether he can hide the eyes of Cheng Yu of Cao Cao's faction in Xiahou Yuan's army.

Anyway, now Zhu Wei can see through the map of the Three Kingdoms game that after Zhang Xiu's army and Xiahou Yuan's vanguard Cao Jun met, Che Xuan did not suspect Zhang Xiu, and smoothly sent someone to lead Zhang Xiu to the rear to find the main force of Xiahou Yuan.

Of course, Zhang Xiu also took the opportunity to transfer the section of the Xianghan Pass area of Bowangpo under his control to the Cao Army's vanguard troops under the command of Che Xuan.

This is also a gift from Zhang Xiu.

In this way, under the guidance of the people sent by Che Zhou, Zhang Xiu led his troops to completely leave the Bowangpo area, and finally converged with the main force of Cao's army under the command of Xiahou Yuan in a village three miles north of Bowangpo.

Of course, Zhang Xiu's army still camped alone next to the camp of Cao Jun, who was commanded by Xiahou Yuan, not to say that the two armies were merged together.

In this way, even if Zhang Xiu was willing, Xiahou Yuan would not dare to agree.

Therefore, after Zhang Xiu arrived with his troops, Xiahou Yuan only invited Zhang Xiu to talk in Cao's military camp, which should also be to discuss Zhang Xiu's surrender, but unfortunately even if Zhu Wei could see the situation of Xiahou Yuan's Cao army camp with the help of Zhang Xiu's eyes, what happened after Zhang Xiu entered Xiahou Yuan's military tent was impossible to know.

In fact, even if Zhu Wei could see it, he wouldn't be able to hear what they were saying.

Therefore, now Zhu Wei can only quietly wait for the development of the situation, to see if everything can be according to Jia Xu's strategy, and Xiahou Yuan can believe Zhang Xiu's fraudulent surrender.

Of course, Jia Xu's strategy this time was not achieved all at once, even if Zhang Xiu succeeded in defrauding Xiahou Yuan and gaining Xiahou Yuan's trust, it was impossible to immediately lure Xiahou Yuan's Cao Jun into Bowangpo.

According to Jia Xu's strategy, this strategy still needs Pang Yanxiong Lu Ying on Zhu Wei's side and Cao Jun, the commander of Xiahou Yuan, to confront Bowangpo for a period of time before they can find an opportunity to complete the next step of the strategy.

Therefore, Zhu Wei is not in a hurry now, as long as Zhang Xiu does not have an accident in the Xiahou Yuan army now.

Soon, Zhu Wei found that Zhang Xiu came out of Xiahou Yuan's military tent safely through the map of the Three Kingdoms game, and it seemed that the two sides had reached some agreement, and Zhang Xiu's fraudulent surrender seemed to have succeeded.

So Zhu Wei relayed the news that Zhang Xiu had met with Xiahou Yuan and returned to his own military camp from Cao's military camp, and Jia Xu squinted his eyes slightly when he heard this, and nodded noncommittally.

In fact, with Jia Xu's understanding of Zhang Xiu, he believes that Zhang Xiu should still be able to complete the first step of the deception task.

As for the later stage of luring the enemy, at the beginning, I was afraid that Zhu Wei would need to sacrifice some troops on his side, and step by step induce Xiahou Yuan to trust Zhang Xiu more, so that he could lure Xiahou Yuan's Cao army into the trap and death in Bowangpo at a critical time.

Of course, now that Zhang Xiu has successfully surrendered, Zhu Wei's side has also begun to plan and arrange for Jia Xu's next step, and immediately ordered Pang Yan on Bowangpo's side to make corresponding military preparations.

These things had been instructed by Zhu Wei before he sent Yi to the Xiong Lu camp, so now Yi Yi can completely follow the plan and help Pang Yan make improvised moves.

In fact, there is no need for the Xionglu battalion on Pang Yan's side to do anything now, as long as Pang Yan does things according to the normal military strategy, and Yi Yi is just reminding him at a critical time.

In this way, Pang Yan, who was on the side of Bowangpo, also sent troops to try to launch several small-scale attacks on the Xianghan Pass area controlled by Cao's army.

This is also to test how effective Cao Jun is......
