Cao Ren's conscience is still there, at least he will not do anything to abandon his comrades.

After returning to Chang'an, meeting Cao Pi, and understanding the current overall situation, Cao Ren's first suggestion to Cao Pi was that he hoped that Xu Huang and Cao Zhen, who had retreated to Youfufeng to rest first, would send troops again, and the troops would be divided into two routes.

Part of it was to quickly occupy various county towns and dangerous places on the east bank of Weishui to prevent Liu Bei's army from advancing eastward.

In that place, Cao Ren retreated too quickly, and he really didn't think of arranging people to guard him for a while, and when he retreated to Chang'an, he remembered that the east bank of Weishui was completely undefended, and now he was in a hurry to make amends.

The other part is to quickly reinforce Zhang He and Guo Huai, who are guarding on the west bank of Weishui, to block Zhao Yun's offensive route to Chang'an.

After Cao Ren rested a little in Chang'an City, he once again led 50,000 troops to the Baochuan Road to fight a decisive battle with Liu Bei's main army.

This was Cao Ren's next strategy to deal with Liu Bei's army.

But. Cao Pixin said that you should pull it down quickly, and the decisive battle is a fart!!

Cao Zhen and Xu Huang, who had just retreated to the right Fufeng, had more than 20,000 troops, and in a blink of an eye, they let you send out, and the 50,000 Chinese troops you brought back by yourself will go to Liu Bei for a decisive battle after turning around and resting. Co-author, do I still have to rely on these improvised "village warriors" to defend Chang'an?!

Before Liu Beijun only entered Guanzhong alone, these families were still reliable. Now that Liu Bei's army has entered Guanzhong with a total of 70,000 or 80,000, do you really think that these Guanzhong families are completely reliable? !

Don't look back, as soon as you leave the city, they will launch a rebellion and tie me up and give it to Liu Bei as a meeting gift.

Well, even if these Guanzhong families don't betray Cao Wei, what about the direction of Wancheng?!

Zhang Liao's side, this is the third time this month that he has sent an envoy to ask for reinforcements. If Guan Yu is allowed to break through Wancheng, then this Chang'an will really not be able to hold it.

In this case, Cao Pi no longer thought about how to fight Liu Bei, he only thought about holding Chang'an and stalemate with Liu Bei.

Anyway, whether Liu Bei is transporting grain from Baochuan Road or Qishan Road, his supply line is too long, and it is impossible to confront him for a long time, in this case, as long as he holds Chang'an, in the end, Liu Bei will definitely not be able to hold on first, and he has to retreat.

What's the decisive battle, it's good to keep the bottom line.

This is what Cao Pi thinks now, and it is also the biggest difference between him and Cao Cao Cao Cao really dares to take risks when necessary, but Cao Pi, a person who has been trained since childhood and took over his father's family business, is not a little worse than Cao Cao in terms of courage.

Therefore, Cao Pi ordered that the Chinese army brought back by Cao Ren should temporarily rest and recuperate for ten days.

Ten days later, Cao Ren personally led 20,000 Chinese troops to Wancheng to rescue Zhang Liao, presided over the defense of Wancheng, and must block Guan Yu's attack and defend Wancheng.

As for Chang'an, Cao Pi continued to sit in Chang'an, and let his confidant Xiahou Shang lead the remaining 30,000 Chinese troops to defend Chang'an.

As for Cao's army along the Weishui coast, Cao Pi also gave an order to "hold on as much as possible, and if things are not harmonious, retreat to Chang'an for temporary refuge".

Cao Pi made it clear that he wanted to delay, delay time, drag logistics, rely on Chang'an Jiancheng, and drag down Liu Bei.

This tactic is very conservative and seems a bit cowardly. But as long as it is dragged until Liu Bei retreats, then Cao Pi can also say to the outside world that he repelled Liu Bei, which is not a shame.

And Cao Pi is still guarding Chang'an Town, at least he didn't run away, and he still has a bit of a gentleman's demeanor.

Cao Pi made such a strategic adjustment, Cao Ren could only sigh, and finally said nothing.

On the one hand, as a vassal, Cao Ren could not make irresponsible remarks about the sovereign's decision, and on the other hand, Cao Ren could not accuse Cao Pi of whether his decision was right or wrong.

Even if he has the heart to fight a decisive battle with Liu Bei, but he can't win, in fact, Cao Ren has no bottom in his heart, Cao Cao is not there after all, and Cao Pi can't give Cao Ren that feeling like the backbone, maybe such a conservative choice is not necessarily a bad thing.

In fact, Cao Pi's decision to give up the decisive battle with Liu Beijun and stick to Sanfu and Chang'an also made Liu Bei a little uncomfortable.

The battle has been fought for half a year, and in this half a year, Liu Beijun's logistics supply has always started from Qishan Road, entered Tianshui County, and then hoarded in Xixian County, and finally transferred from Xixian County to Longshan Road. This supply line is too long.

Although this is a helpless thing to do, and it is also to ensure the safety of the supply line, in these years, the transportation of grain and grass not only requires a large number of people, but also the food and drink of these people have to consume part of the grain and grass.

The longer the supply line, the more grain and grass will be consumed by the people, and the smaller the amount of grain and grass will be sent to the front.

Therefore, even with Zhuge Liang, a person who is good at calculation, in charge of logistics, Liu Beijun has always been under great pressure on logistics.

Now that the Bao Slope Road has been opened, Zhuge Liang will no longer need to go through the distant Qishan Road to organize the transportation of grain and grass, and he can directly take the Bao Slope Road to transport grain, but there is also a problem with the Bao Slope Road to transport grain, that is, there are not enough hoarding points, and the risk will be relatively large.

The exit of the Bao Slope Road is in Guanzhong, where the power of the Cao army is still very large, and you can't hoard too much grain and grass in the barracks, otherwise once the grain and grass are burned by the Cao army, it will be a loss in vain.

Although the road at the exit of the Baochuan crossing is narrow, as long as you go out for a while, you will enter the Guanzhong Plain, and if you build a granary for storing grain here, it is basically no danger to defend, once the granary is burned down by the enemy, the whole army will fall into a situation where there is no food available.

Therefore, to transport grain and grass from the Bao Slope Road, it is necessary to strictly calculate the daily grain consumption and arrange the time for transporting grain back and forth, and there can be no big mistakes, otherwise it is easy to make mistakes.

This is not a test for the people who transport grain, but it is a very big test for the calculation ability of the logistics team headed by Zhuge Liang.

If Liu Bei stays in Longshan, at least there is a grain point in Xixian County as a buffer, but once he leaves Longshan, the pressure of logistics will be all on the Bao Slope, that is, on the calculation power of Zhuge Liang and others.

With such logistics and transportation, the fault tolerance rate is too low, and Liu Bei does not dare to come out of Longshan easily.

As for the west bank of Weishui, after Zhang He and Guo Huai received the rescue from Xu Huang's troops, the strength of the two sides temporarily restored the balance, and the Cao army under the leadership of Zhang He and Xu Huang also stabilized the defensive line, and the two sides were stalemate for a while.

Things have come to this point, and Liu Bei is also a little hesitant whether to continue to enter the army and attack Chang'an.

Attacking Chang'an was the ultimate strategic goal of this Northern Expedition, and Liu Bei was to occupy Chang'an, the old capital of the Han Dynasty. But now that the battle has been fought, the situation is completely different from when he was planning in Hanzhong at the beginning.

In the Guanzhong area, Cao's army now has nearly 100,000 troops, and the whole line has shrunk and retreated to Sanfu and Chang'an.

And Liu Beijun has only 70,000 or 80,000 troops, and with such a comparison of troops, Liu Beijun wants to conquer Chang'an, which is somewhat wishful thinking.

In addition, now that Liu Beijun has been fighting for more than half a year, the logistical pressure is very great, and the accumulation of rest and recuperation in the first two years has consumed seventy-seven eighty-eight in this half-year campaign.

It's not that you can't continue to fight, after all, there is still a little bit left in the foundation, but if you continue to fight, when the end is exhausted, it will really hurt your muscles and bones again.

This injury does not refer to Liu Bei's group's injury to the muscles and bones, but to the entire Shuzhong family, who will break the muscles and bones.

This is very detrimental to the rule of Liu Bei's group.

Even if it occupies Chang'an, but the most elite area of Liu Bei's group is still Yizhou, if the Yizhou family has a confrontational attitude towards the rule of Liu Bei's group, then what Liu Bei has to do next is probably to make every effort to maintain internal stability, and there will be no chance for the next Northern Expedition.

Now Liu Bei is not young, decades of conquest and displacement have made Liu Bei realize that under the current world, you can restrict and suppress the family and let the people live as well as possible, but it is impossible to completely eliminate the family, and even sometimes you have to rely on the family to maintain your rule.

Liu Bei is also old, and he doesn't want to offend the Yizhou family too hard, which doesn't do him any good.

And just when Liu Bei was still hesitating whether to enter Guanzhong, Zhuge Liang wrote a letter of guilt to Liu Bei.

The content of this letter of guilt is that Zhuge Liang pleaded guilty to Liu Bei because it was unfavorable to mobilize the people of Shuzhong to participate in the war.

As early as the moment of the breakthrough of the Bao Chuan Road, Zhuge Liang sent an order to Yang Hong and Qin Mi in Shu to recruit troops, asking them to launch a general mobilization in Shuzhong, with the male protagonist fighting and the female protagonist supporting the Guanzhong battlefield.

However, the response of the Shuzhong family was very slow, and Zhuge Liang's mobilization order had been sent to Chengdu for almost half a month, and the Shuzhong families began to write letters to Zhuge Liang one after another, telling about various difficulties.

As for the soldiers, they didn't see any of them.

Regarding the attitude of these families in Shuzhong, Zhuge Liang actually knew very well what was going on, so he strictly ordered Yang Hong and Qin Mi, who stayed in Chengdu, to send a general mobilization order, and on the other hand, he sent a letter of guilt to Liu Bei.

And along with this letter of guilt, there was also a secret letter written by Zhuge Liang to Liu Bei, the content of which was to seek Liu Bei's opinion.

Zhuge Liang was not on the front line after all, and he didn't know the actual situation on the front line, so he just asked Liu Bei if he still had the strength to attack Guanzhong.

If Liu Bei is determined to march into Guanzhong, then Zhuge Liang will hand over the logistics management to Yang Yi, leave Hanzhong temporarily, go to Chengdu in person, personally supervise this general mobilization, and transport soldiers, grain and grass materials to Guanzhong.

But if Liu Bei still plans to stay in Longshan Road and hold his troops still, then Zhuge Liang suggested that since the broken Longlong has been completed, then Chang'an is in a state where it can be attacked at any time, so it is better to accept it when it is good.

Don't forget, there is a Liangzhou behind us, which is not completely eaten.

Don't go back and dry Liangzhou for too long, people's hearts have changed, take advantage of our attack on Guanzhong to have a backstab. This is no small matter.
