If Deng Ai does not want to repeat Zhuge Liang's mistakes, he must solve the problem of logistics supply and be prepared for a protracted war.

If you only want to fight and decide quickly, then the logistics supply may not be so sufficient. Once the battle is in an unfavorable situation and the food supply difficulties arise, how can you fight the battle?

Therefore, whether it is Cao Liang or Deng Ai, he is never stingy in preparing for logistics and supplies for food and grass. After pacifying Yongliang, Cao Liang has already begun to plan to attack Shu. In Cao Liang's original plan, attacking Shu was earlier than attacking Wu. After all, from an objective perspective, the strength of Shu was not as strong as that of Wu. Ordinary conquests were often easy to start and difficult to start, and then far away, just like Qin destroying the six countries. The weakest South Korea was the most recently, and the strongest Chu and the farthest Qi.

After Cao Liang pacified Guanlong, his momentum was strong. If he led his disciples to Guanlong south, it would be a good opportunity to break Shu.

However, Cao Liang did not act rashly. After all, the army had a momentum at that time, but the problem of logistics supply was not solved. If the attack on Shu was successful, it would be fine to attack Chengdu in one go, but if the logistics could not keep up, the Wei army would definitely be in a dilemma.

Therefore, Cao Liang did not rush to attack Shu, but made sufficient preparations and actively prepared for war. Only when everything is ready and everything is done can the curtain be opened for attacking Shu.

It was only because of the change of the situation that Cao Liang decided to destroy Wu first and then attack Shu, and concentrate his troops to attack Wu, leaving only Deng Ai's left army stationed in Guanlong and continued to prepare for the attack on Shu.

Although the plan to attack Shu slowed down, the preparations did not stop at all. In the past two years, the source of food and grass resources has been continuously transported from Guandong to Guanzhong, and the material reserves have reached an unprecedented level. Even if Deng Ai squandered some of them, the remaining food and grass supplies would be enough for him to use for a few years.

However, these food and grass materials reserves in Guanzhong are not enough to solve the problem of food and grass supply on the front line. The endless towering Qinling Mountains are like a natural danger, blocking between Qin and Shu, becoming an almost insurmountable barrier.

Deng Ai knew that if these food and grass materials could not be transported smoothly to the front line of Hanzhong or even to the hinterland of Yizhou, then no matter how much food and grass was stored, it would be meaningless. Solving the transportation problem was the most critical point in the war against Shu.

Although Deng Ai has collected more than 30,000 civilians, if not enough, he can continue to recruit more than 20,000 people in a short period of time, Deng Ai dares not fully guarantee whether it can really meet the food transportation needs of the frontline. After all, such large-scale and long-distance transportation of the Wei army has not been implemented yet, and only after the war begins can we try it.

What Deng Ai can do now is to ensure the full reserve of personnel and materials to the greatest extent, be prepared to deal with difficulties, and take logistics transportation as a top priority.

The only good news now is that Yan Yu has withdrawn the guerrillas deployed on the periphery, which can be regarded as clearing a major obstacle for the Wei army.

If these Shu army guerrillas continue to be active in the foothills of the Qinling Mountains, it will be a great threat to the logistics transportation of the Wei army. If the food supply cannot be guaranteed, the main force of the Wei army will be deeply affected.

Deng Ai had no special good way to clear out these guerrillas. After all, there were a few small-scale troops hidden in such a vast mountain range, which was really a needle in a haystack.

Under such circumstances, if the Wei army wants to ensure that the food and grass are not robbed, they can only send a brigade of men to escort the food and grass. It is already quite difficult to transport grain itself. If a large army is sent to escort it, the burden will be even heavier. Most of the food and grass will be consumed halfway. The food and grass that can be transported to the front line will probably be very small, and it will not meet the needs of the front line's army at all.

Moreover, sending troops to escort food and grass invisibly increased the burden on the field legion. Originally, they had sufficient troops to attack the tough, but they were likely to fail due to insufficient troops.

In short, the existence of these guerrillas will have a great impact on the Wei army. Although it is not fatal, it is enough to make the Wei army exhausted.

This is probably also the original intention of Jiang Wei to deploy these dozen guerrillas. Although it cannot pose a fatal threat to the Wei army, it can at least destroy the Wei army's food route and disrupt the military morale of the Wei army. This will sharply reduce the offensive momentum of the Wei army, and be depressed, and eventually retreat without fighting.

However, Jiang Wei's plan has been completely failed. Yan Yu abandoned his martial arts and withdrew all the guerrillas scattered around Hanzhong to Nanzheng. Nanzheng's defense has been strengthened, but these tampering on the outside no longer exists. Yan Yu's move has benefited Deng Ai for a lot of trouble.

The logistics transportation plan that Deng Ai has implemented this time is saturated supply, and he invests a lot of manpower and material resources at all costs, and is not afraid of waste of materials. Even if he spends three stones of grain to transport one stone to the front line, it is worth it.

In addition, Deng Ai couldn't think of a better way. After all, the transportation of food and grass is real and there is no need to play anything. Under the current conditions, only this saturated supply method can meet the needs of the front-line army.

As for eating from the enemy and obtaining supplies from Shu, this is not within Deng Ai's consideration, because Jiang Wei's Hanzhong defense plan was to follow Sima Yi's method, strengthen the walls and clear the fields, and the wilderness was infertile. How could he leave food and grass for the Wei army to eat?

After the Wei army entered Hanzhong, they were likely facing a thousand miles away from the land. All the food and grass supplies had to be realized through long transportation lines. Other ideas were unrealistic and were not within the scope of Deng Ai's consideration.

The saturated supply method proposed by Deng Ai was also recognized by Cao Liang. Cao Liang repeatedly emphasized in his correspondence that before the troops move, food and grass should be taken first, and difficulties should be taken more seriously. Food and grass supply must be kept up, and there must be no forced retreat because of the exhaustion of food.

We must use all existing conditions to increase transportation efforts and ensure the supply of the front line. The saturated supply method proposed by Deng Ai is a good way to solve the transportation difficulties of the Qinling Mountains. It is worth paying some of the costs now. We must look at the problem from a long-term perspective and have a sense of the overall situation. In order to succeed in the major plan of attacking Shu, all parties must make practical efforts. There must be no slackness, nor can we have blind optimism, face difficulties, overcome difficulties, and strive for the final victory.
