Feng Yong, who was far away in Tongguan, naturally did not feel Lu Xun's gaze.

It was even more impossible to hear Lu Xun's inner call.

At this time, he was sitting on the Taishi chair, with his hands resting on the armrests on both sides of the chair.

There were people and chairs leaning against the wall, hiding in the shadows, silent.

From his position, he could have a panoramic view of the combat staff room just across the door.

People in the war staff room could see the outline of the Central Protector when they raised their heads, but no one could clearly see the expression on his face.

The big room where the staff team was busy all night was filled with big candles that could only be used by the royal family and top wealthy families in the Wei Kingdom.

The entire combat staff room was illuminated as brightly as day.

After receiving the military order from the Central Protectorate, the headquarters of the staff group of the Central Protectorate did not delay for a moment. They set out from Chang'an and arrived at Tongguan only one day later than Governor Feng.

The arrival of the staff team finally brought the latest situation of the entire battle that Feng Duhu needed most - of course it could not be the frontline battle report of that day, but it was the latest news that the rear could grasp.

After arriving, they did not have any rest time and had to immediately formulate a battle plan based on the current battle situation.

Various partially enlarged maps, hastily made sand tables, and messy documents...

Some of the operational staff members were red-faced when they were arguing, some were writing and drawing against maps in their notebooks from time to time, some were too hot and simply went shirtless, wearing only a vest...

Jiang Wei and Liu Yin are also participating, and they are conducting war chess deductions on the sand table.

I don't know whether it was too hot or too nervous, but their foreheads were already covered with sweat.

There are people around them who are making suggestions, checking for omissions, and pointing out possible omissions.

Making a battle plan is not just about randomly drawing on the map and waving your hand to tell the army how to move.

Rather, it should be based on the actual situation of both the enemy and ourselves, such as troop strength, food and grass, etc.

Then based on the geographical situation we have, we must consider where the possible battle locations will be, what we will encounter on the march, how to deal with it, how to deal with it...

Things in the world are unpredictable, and wars are even more unpredictable. No matter how good the plan is, it is impossible to take all accidents into account.

But as the saying goes, "If you don't fight but the temple is the winner, you have to count it as more; if you don't fight but the temple is the loser, you have to count the less. More is the winner, less is the loser, and what's more, nothing counts!"

The more you think about it, the more confident you will be.

The battle situation ahead is not very optimistic - whether it is based on the current information or the deduced prognosis.

The staff group must not only deduce the most likely battle situation in the shortest possible time.

At the same time, corresponding plans must be formulated based on these battle conditions.

Time is tight and tasks are heavy.

Many people's eyes were already covered with bloodshot eyes, and they had not slept a wink all day and night.

But almost everyone drank strong tea, no one wanted to sleep at this time, and they all acted very excited.

the reason is simple.

What was originally an inconsequential battle in Gaodu has now evolved into a major war.

Judging from the deduced battle situation, the decisive battle between the Han Dynasty and the Wei bandit armies in Luoyang and Hanoi is likely to have arrived in advance.

Unknowingly, it was already white outside the window.

Gongsun Zheng took a document and hurriedly walked through the door and from the combat staff room to Feng Duhu:

"Zhongduhu?"

Feng Duhu's lowered head subconsciously raised his head when he heard the sound.

At the same time, he closed his eyes hard and shook his head, as if he wanted to shake off the fatigue:

"how?"

"Zhongdu Hu, this is the plan everyone has put together."

Gongsun Zheng was from Longxi.

From the time when the Prime Minister captured Longyou in his first Northern Expedition and Feng Duhu formally established the staff group, Gongsun Zheng has been the chief of staff.

Over the years, the staff members have changed one after another.

Most of them join the military and serve as the backbone of military officers.

But Gongsun Zheng never moved away.

When he was in Longyou, he was the chief of staff of the Qiang Protector's Office. When he arrived in Liangzhou, he was the chief of staff of the Liangzhou Governor's Office. As of now, he is the chief of staff of the Zhongdu Protector's Office.

Although they are both chiefs of staff, their qualities are definitely different.

On weekdays, Duhu Feng holds the general direction, while General Guan is responsible for the main affairs of the army.

But when it comes to specific matters in the army, such as the allocation of food and grass, recording rewards and punishments, improving military discipline, camp arrangements, etc., Gongsun Zheng still has to be asked to arrange manpower.

It can be said that if General Guan is Feng Duhu's military commander, then Zhang Xiaosi is the military commander.

But General Guan had to lead the army on expeditions from time to time, so Gongsun Zheng was Chang Shi's substitute when General Guan was away.

There are a lot of documents in my hand, a very thick one.

Feng Duhu flipped through it casually, and found that the writing on it was rather sloppy. He was probably in a hurry and didn't have time to copy it again.

After looking at it for a few times, Feng Duhu felt that his eyes were getting even drier.

"That's right. Let the cook cook some delicious food so that everyone can eat and replenish themselves before going to have a good sleep."

Feng Duhu closed the medicine in his hand and gave an order.

As the coach, he also needs to carefully review all the preparations they have made, and at least be mentally prepared for the most likely situation.

Time was tight, and Feng Duhu was also in a hurry.

But no matter how anxious he is, it is still difficult for a clever woman to make a meal without rice because the troops at hand are insufficient.

The troops transferred back from Caoqiao Pass are still on the way.

Another important reason is that Chang'an is seizing the opportunity to transport a batch of grain and grass to Tongguan.

But I think it shouldn't take too long, maybe five or six days at most.

I have to thank Emperor Xiaowu for this.

Because when Emperor Xiaowu conquered the Xiongnu, the Wei River had insufficient transportation capacity, so he dug an artificial canal next to the Wei River.

This Guanzhong canal starts from Kunming Pool in Chang'an in the west, runs parallel to the Wei River for more than 300 miles, and finally merges into the Wei River in the east.

(This canal was used until the late Tang Dynasty. It has disappeared now, but it has been discovered by archeology. If you are interested, you can watch the third episode of "Chan Ba ​​Long Song")

Whether it's the Wei River or the Guanzhong Cao Canal, it can't drive the big ships or even giant ships in the big rivers.

But the advantage is that the water flow is smoother than that of big rivers.

The ships that transport food and troops are not going to fight. The ships are small and don't have enough carrying capacity, so they have to make up for it by quantity.

No matter what, it is much better than simple land transportation.

So in the past few days, you must be ready to go out at any time.

"Boyo, Xiuran, you two stay, I have something to say."

It was daybreak, and the shadows of the candles seemed a little dull.

Coupled with the fact that no one blocked the candlelight, Zhong Duhu, who had been hiding in the shadows, could finally see clearly.

Zhong Duhu, who had spoken very little all night, also had a tired look on his face.

After everyone had retreated, Jiang and Liu stepped forward and saluted, "Zhongdu Protector?"

"The food and grass shipped from Chang'an will probably be enough in two days. You two, have a good rest today. We will assemble the army tomorrow and set off the day after tomorrow."

Jiang Wan has always been a trustworthy teammate in raising food and fodder for the frontline troops in the rear.

Rather than being a pig teammate like Wei Yan.

"Set off?"

Liu Yin was startled.

"Where to go?"

Jiang Wei's eyes lit up.

Feng Duhu rubbed his forehead and said in a tired and weak tone: "Go to Hangu Pass."

"Hangu Pass!?"

"right."

Feng Duhu nodded.

I was really too lazy to get up and point at the map. Anyway, I had been staring at the map for the past few days, so the two of them should have memorized it roughly.

The Hangu Pass mentioned by Feng Duhu naturally refers to the Hangu Pass of the Qin Dynasty, not the Hangu Pass of the Han Dynasty.

Emperor Xiaowu wanted to expand Hangu Pass in Guanzhong, so he moved Hangu Pass eastward to the gate of Luoyang.

Therefore, although Hanhangu Pass can be regarded as a pass, it is more of an administrative geography concept.

Compared with Hanhan Valley Pass, Qinhan Valley Pass, which is closer to Tongguan Pass, is a truly dangerous military pass.
