In order to cooperate with the advance of the 50,000 Shu army, Fa Zheng had already presided over the advance of the logistics troops.

The so-called three armies did not move the grain and grass first, and most half a month before the departure of the army, the grain and grass logistics units began to set off first to clear the way for the army.

A soldier's life is to be lost on the battlefield, not in a useless place.

On the way to the army, the soldiers are the masters, and the auxiliary soldiers and the people are the nourishment, and they must burn themselves to protect the soldiers.

Therefore, the believers of the Wudou Rice Sect in Hanzhong have poured blood mold.

In order to eradicate Zhang Lu's influence on Hanzhong, Pang Xi forced the Hanzhong people to give up their belief in the Wudoumi Sect, and if there were still those who were unwilling to give up, they would all be accepted as coolies.

Later, Pang Xi mobilized the people of Hanzhong to encourage each other to inform, and found out the people who were still missing Zhang Lu and hated the Shu Kingdom, which caused Hanzhong to jump for a while, and also accumulated a lot of manpower for the Northern Expedition.

This time, a total of 70,000 auxiliaries and minfu were conscripted to transport grain and grass, and of course, most of them were believers in Hanzhong.

However, Rao is like this, before the official march, after the logistics troops took the lead in setting off, Pang Xi and Fa Zheng still felt that it was difficult for Shu to go to the sky.

It is really not the same thing to go by yourself and to lead a large army, but it is not the same thing to lead more than a thousand vanguard troops and tens of thousands of main troops.

Fa Zheng and Pang Xi made full use of the waterway that coincided with Qishan Road in the direction of the stream, and used the waterway to transport grain and straw materials, trying to reduce the burden on the auxiliary soldiers and civilians, but the facts told them that even if they used water, it was not as convenient as they imagined.

Because these rivers do not have much water and have limited carrying capacity, they cannot use very large boats, but can only be transported little by little by small boats, otherwise they cannot move forward.

But in this way, the carrying capacity will not be able to meet the requirements of the advance of the Shu army.

There were also a lot of troubles in the transportation of manpower, such as the difficult roads, potholes, mountain roads, narrow places, steep places, carts difficult to move forward, and the news that the auxiliary soldiers and people who transported the grain and straw were tired and fell to death and several people were constantly coming.

In this way, the logistics troops naturally complained, and Pang Xi had no choice but to order the troublemakers to be severely punished, and a number of heads were cut off before the situation was barely suppressed.

That being said, the logistical challenges won't be solved by this.

Every time you advance a distance, you have to pay a huge price for this, which is really too difficult for the advance of the Shu army.

Although I have made a lot of assumptions and explored a lot of data, there are still some discrepancies when it comes to actual action.

After discussion, Pang Xi and Fa Zheng had to slow down the advance of the army relatively in order to slightly cooperate with the advance of the logistics troops.

To avoid the person in charge of the logistics unit crying in front of them every day about how many people have died here, how to force them to die, etc., in the face of such a posture, Pang Xi and Fa Zheng are also annoyed.

The Shu army on the Qishan Road was slow to act for this, often stop-and-go, stop-and-go, in order to cooperate with the grain transportation of the logistics troops, which was about to become the norm.

In this case, Pang Xi and Fa Zheng have no good way.

The waterways along the road are not wide, the water level is not deep, the carrying capacity is too limited, the army needs more grain and grass to advance, the road is not easy to walk, and the speed of advance is far lower than expected.

In order to conform to reality, Fazheng had to relax, relax, and relax again and again the time needed to advance, and the demand for grain was getting bigger and bigger.

There's no way around it.

But things can't be left undone, the Northern Expedition can't be carried out, everyone can only grit their teeth and move forward, and contribute their livers to the great cause of the Northern Expedition at the risk of 770 and baldness.

Fa Zheng racked his brains to find a solution to the problem, but after thinking about it, he still couldn't do it in the face of the powerful power of nature and the limitations of human science and technology.

He didn't know that a few decades later in another time and space, a person with the same ideals, ambitions and talents as he would march north step by step with such difficulty, defeating again and again, defeating again and again.

He is very smart, very capable, and very powerful, and he concentrates all his strength on doing great things, and even if he is so, he can't solve the problem of the bumpy road of the Northern Expedition.

If it weren't for the bumpy road of the Northern Expedition, maybe history would have been rewritten.

Unfortunately, nature doesn't play with you.

The geniuses born in this era, no matter how hard they try, cannot reverse the disadvantages brought about by nature.

The Shu army walked forward step by step.

Around the beginning of July, the news of the Shu army's advance was obtained by Guo Peng, and according to accurate intelligence, Guo Peng learned that the route chosen by Liu Zhang's group was not to take Guanzhong directly, but to take Liangzhou directly.

Take the path of Zhuge Liang's First Northern Expedition and the Fourth Northern Expedition.

The main force of the Shu army, 50,000 troops, took the Qishan Road and marched along the route of Hanzhong, Wudu and Hanyang to Hanyang County, Liangzhou.

As for Guanzhong, they took a defensive position, guarded the major crossings into Shu, and blocked the roads, so that Guo Peng's army could not do it even if they wanted to attack.

Chencang Road, Bao Slope Road, and Meridian Road, the three important roads that Guo Peng sent people to strictly survey, all detected the Shu army's operations of destroying roads.

The already difficult path has become even more difficult.

In response to this, Guo Peng immediately convened a military meeting in Chang'an, attended by Guo Jin, the crown prince of Wei, to discuss this important information.

Xun You and Chen Gong immediately pointed out Liu Zhang's intentions, and judged that there were high-ranking people around Liu Zhang.

"The land of Longyou is the shape of the world, when Emperor Guangwu was in turmoil, cut off Longyou, Emperor Guangwu sent a large army to attack Long, four years can not win, with the land of Longyou projectiles to resist Emperor Guangwu for four years, it can be seen that the terrain of Longyou is dangerous."

Chen Gong pointed to the map for analysis.

Xun You analyzed the movements of the Shu army.

"The Shu army went out of Shu and took Longyou directly, and it was bound to want to capture Longyou, cut off Longdao, and hold Longdi to resist our army, so that our army could not enter Longyou, could not capture Longyou, and entered the whole territory of Liangzhou, while the Shu people could be in Longyou Tuntian.

In Longyou Tuntian, to solve the problem that Shu grain is difficult to deliver, and can occupy Longyou to raise horses, in order to train cavalry, then a few years later, the national strength rose sharply, Longyou cavalry out of Longlong, rampant Guanzhong, the situation is no longer what it is today. ”

Lu Sujin said: "Liu Jiyu has capable people around him, he did not want to compete with our army for Guanzhong, but seized the opportunity and entered Longyou, judging from the situation that the generals of Liangzhou were divided into many places and scattered sand, the generals of Liangzhou are very likely to be unable to resist the Shu army, then Longyou is obtained by Liu Jiyu, and the Shu people can open up the situation." ”

From a professional point of view, the strategists suggested that Guo Peng immediately react to this matter and make arrangements in advance, so as to prevent the Shu people from getting Longyou, lifting the situation of trapping the dragon, and soaring for nine days.

Otherwise, the situation will become very difficult to deal with.

If necessary, gritting his teeth and sending troops to Longyou, he will strive to occupy Longyou before the Shu people occupy Longyou.
