Ma Chao was besieged in Qi County, where Jia Xu was planning to take advantage of Ma Teng's empty troops to steal territory, and there was also a force in the south of the Guanzhong Plain.

That person was Lu Su, the prefect of Hanzhong appointed by Liu Bei.

Lu Su, who was in charge of Nanzheng, only heard about Mahan serving the king and attacking the pseudo-DPRK in Chang'an in early September. It has been more than half a month since Mahan actually decided to send troops.

When Lu Su learned the news through the fast horse scout, Han Sui had been clamoring to attack Chen Cang for seven or eight days, and Ma Chao had been besieged in Qi County.

Lu Su’s main task this year is to carry out large-scale construction in Chencang Road, digging the former Western Han River waterway with landslides and landslides. He also used gunpowder during the construction process. Finally, the progress was quite smooth and would not delay next year’s Northern Expedition.

Lu Su’s other two tasks are to try to save as much food as possible in the Hanzhong Basin this year to ensure that the Northern Expedition Army can eat at least half a year next year, and will continue from the beginning of spring to the autumn harvest. If more food can be stored and insurance for possible accidents, it would be even better.

As mentioned earlier, before the old waterway of the Western Han Dynasty was restored, the grain from Hanzhong was transported to the front line of Chang'an. Basically, only one stone could arrive for four stones, and three stones would be eaten on the road, with up to 75% of the transportation loss, which was really too difficult to walk on the Qinling Mountains.

However, after the former path of the Western Han River is opened next year, as long as you can take a small boat, even a raft, to complete the last 160-mile mountain road across the Qinling Mountains, the transportation cost can be at least half.

Maybe three stones of grain will be transported out by then. As long as you eat one stone on the way, the remaining two stones will be able to enter the Guanzhong Plain.

Lu Su’s last task this year is to always keep a close eye on the trends of the Guanzhong warlords, collect information in a timely manner, and repay it to Liu Bei.

At the same time, Lu Su will also use existing information to return to Li Su's letters to discuss how to alienate the internal relations between the pseudo-DPRK in Chang'an and the pseudo-DPRK. Or "how to divert the military attention of the pseudo-DPRK in Chang'an and ensure that the main force of the enemy should be mobilized as much as possible before the Northern Expedition next year, so that they should not appear directly on the Northern Expedition route to block the entrance at the moment when the Northern Expedition was just beginning."

All this work, Liu Bei gave Lu Su, must be implemented until the end of October, when the Qinling University was closed. After the heavy snow was blocked, the princes of Guanzhong would not be able to cross the Qinling Mountains to attack Hanzhong. Only then could Lu Su return to Chengdu to hand over the New Year and then change defenses with Zhao Yun.

Because he was responsible for intelligence collection and pre-war smoke bomb deception, Lu Su certainly attached great importance to Han Sui and Ma Teng's battle situation and responded immediately.

He immediately discussed with Fa Zheng, the county magistrate of the Sanguan and the commander of the Sanguan, who brought the news, how to deal with it. (Because the first piece of information Lu Su received was that Han Sui was attacking Chen Cang, which was less than fifty miles away from the defense zone of Fa Zheng, so Fa Zheng was the first to know. Sanguan was originally a small county, with only a county magistrate. In recent years, due to its increased importance, it has been upgraded to a county magistrate. In addition, the commander of the checkpoint was also appointed by Fa Zheng.)

Lu Su asked, "Xiaozhi, what should our army do if this situation is done? It is definitely impossible to advance the Northern Expedition, because Han Sui's attack led to Li Jue and Guo Si focusing on Chen Cang in advance.

Han Sui had many troops but was not good at it. As early as the fifth year of Zhongping, he led more than 100,000 rebels to siege Chen Cang. He was defeated by the king and Huangfu Song, and lost tens of thousands of troops. Even if we attacked with Han Sui, we might not have been able to increase our combat power than fighting alone. Instead, it would have unevenly divided the spoils and led to a melee.

But if we have no response to Han Sui's actions and act too much, with Jia Xu's wisdom, we will definitely suspect that we are ready to go and have other good plans. Even if we want to act, we have to make some symbolic support to Han Sui's attack, right?"

Fa Zheng touched his smooth chin, which was not yet bearded, and wanted to "twist and contemplate", but unfortunately his beard did not cooperate. When Liu Bei defeated Han Suiqian, he passed by Mei County. At that time, Fa Zheng was only fourteen years old. Now, even if he has been an official for several years, he is actually only twenty years old and has won the championship.

Fa Zheng thought for a long time and said, "Mr., I remember that the king and the right general had ordered that if there was indeed a good opportunity, they could also act cheaply and harass the enemy without exposing our army's Northern Expedition plan...

Over the past year, in order to inquire about the military situation in the north, the Fujun also divided the civilians of Baozhong County to rebuild the wreckage of the more than 20-mile plank road burned by Chengji last year during the slack season.

It would be better to take advantage of the autumn harvest, and the remaining grain in the four fields of Guanzhong has not been cut off. Guo Si and Zhang Ji's soldiers were attracted by Han Sui Ma Teng. We went out of the plank road with a small number of elite soldiers to Wuzhangyuan, backed by the plank road, and the east was Wugongshui. We set up a camp to grab grain according to the danger.

The food and grass they have been harvested can be stored on the spot in the Xinli Camp in Wuzhangyuan, or take a 30-mile plank road and transported back to the outpost of the military farm in Taibai Mountain. In this way, it is better to act like "our army is not in a hurry to fight the Northern Expedition, but will not give up on the Northern Expedition."

Let the enemy further believe that we are afraid that the enemy will see through Han Xin's story, so we will do the opposite and plan to go on the Baoxi Road to fight a protracted war, relying on the grain robbed from Guanzhong every year during the autumn harvest season to support the future Northern Expedition.”

The military strategy emphasizes the fact that it is virtual, and the reality is virtual. Therefore, when Han Xin pretended to walk on the Baoxie Plank Road and actually took the Chencang Road to the north to attack Guanzhong, it may not be that Liu Bei and Li Su would still choose this now.

In addition, Jia Xu also knows that Chen Cangdao is much more difficult than Han Xin at that time, and he can really cheat him. Maybe he will think, "Han Xin has reported the answer, and he will never think that he can copy it again. At present, the Chang'an pseudo-Korean has a lot of defensive forces in Chen Cang, but Zhang Han was not unprepared at that time."

As for whether he would believe that Liu Bei plans to take the Baoxi Road in the future, it depends on whether the harassment war this time and even in the future is effective.

If you use a small amount of troops to harass and grab grain, and you don’t need to eat much food, you can hoard it with a sufficient balance to subsidize the food consumed during the future full attack by the army. This account can be calculated, and then the probability of success of deception is very high.

If the harassment and robbery of grain is not effective and even one's own people think it is not feasible, then why have you talked about cheating Jia Xu?

There is no right or wrong in the strategy itself, the key is acting.

After hearing Fa Zheng's adventure, Lu Su was a little moved, but he was not very relieved: "Xiaozhi, you and the king had a path of Baoxia last year, but they were defeated in Wuzhangyuan. Isn't it enough to learn the painful lesson of more than 4,000 soldiers being damaged? Why do you have the confidence to not lose your troops and generals this time, and you can still get food?"

Fa Zheng also held his breath and wanted to turn the tables when he heard this question: "It's time and time! At that time, the king's strategic direction was not clear and his troops were insufficient, so he attacked Chang'an. He was thinking of Wang Yun. Lu Bu's strength might be the same as Li Jue and Guo Si. At this time, Wang Yun and Lu Bu could gain the upper hand if he added a few thousand troops.

So once Lu Bu is defeated and Wang Yun is killed, our army, as reinforcements, will be completely at an absolute disadvantage. In addition, it has already advanced eastward for more than a hundred miles along Weinan at that time, how can we not be defeated? Our purpose today is very clear, which is to lay a nail in Wuzhangyuan, thinking that it will take a long time to do so.

The troops don’t have to go far away, so they grab the surplus grain near Mei County. Moreover, our Legal family is the largest prominent family in Mei County. If I were asked to lead the troops, I would say hello to some wealthy families in Mei County, and maybe I could convince several wealthy families to surrender with their grain. At worst, we promise that after the Northern Expedition was successful, the military rations they sponsored this year will be returned triple!

As long as they have confidence in the king, it will be no problem to attract some people with a large stock, even if Li Jue reacts, he will have to get the news at least two days. It will take another two days for him to send troops from Chang'an or Chen Cang to Mei County. Isn't it enough for us to get the transportation?

Finally, if I take action this time, the elite troops I brought are not comparable to those of the peasants and soldiers a year ago. This year, in order to prevent Hanzhong from losing money, the king did not want to leave more troops to consume Hanzhong's food, so all he left were all elite soldiers. There is a battalion of the camp guarding the gate of Dasan Pass, and there is also a camp in Taibai Mountain in the northern section of Baoxie Road to cultivate farming on the spot.

We will focus on the camp, relying on the Wugong River at the entrance of the plank road, establish a camp, cut down Wugong Mountain, and build camps. Even if the bandit army comes with tens of thousands of troops, it is impossible to break through the Wuzhangyuan camp in a casual manner! We will only lay a nail in Wuzhangyuan and do not advance, just a little bit of troops, so that the enemy will not know the reality and bones are stuck in the throat, which is disgusting for three months in the first half of the year. It will divert the attention of the enemy and divide the enemy's defense, which is enough to support the real direction of the future Northern Expedition."

After some conditions were improved after some of the conditions that had been lost last year, I went again this year. This style of play is actually quite similar to the historical facts that Jia Xu taught Zhang Xiu to pursue Cao Cao's "to pursue the victory by defeating the soldiers, you will definitely win."

Although Fa Zheng is only twenty years old, almost all the IQ he has developed after years of training is seen in this strategy.

"In this way, I was afraid of my hands and feet. I only thought about the shadow of the last year's defeat. I didn't expect that I could do the opposite and lure the enemy..." Lu Su thought about it and thought it was quite feasible for a moment, but he was cautious after all, so he added some details in the end and asked:

"But, Xiaozhi, if you want to go to Wuzhangyuan to establish a camp in person, how can you defend Sanguan? What if Zhang Ji sees your banner appearing in Wuzhangyuan and thinks that Dasanguan is empty and takes the opportunity to attack? You are the commander of Sanguan."

Fa Zheng: "Don't worry, I'm not in vain this year. I have also seen all the military Simas sent to me by the king. They are quite talented in guarding the pass. One of them was Liu Yan's surrendered general, named Zhang Ren. Although his official position was not high under Liu Yan's tent, he also blocked General Gao Shun in Jiange for a year.

This person is a little scholar, and after I sent him to me, I mentioned him again. Now that I am not here, he is more than enough to guard the pass with the Sima of another department. If Zhang Ji dares to think that Dasan Pass is empty, he will definitely ask him to lose his troops and lose his generals on the wall of Dasan Pass, but like Yangping Pass, there are hundreds of Zhuge crossbows.
