Seeing everyone next to him looking over, Feng Yong handed the secret letter to Gongsun Zheng, with a gloomy expression on his face: "The Cao thieves in the east of Longshan have made some unusual moves."

To be precise, it was the Wei army on the Yuezhi City side that showed signs of mobilization.

Gongsun Zheng took it, glanced at it, and said in surprise: "How is it possible? How can Cao Cao be so well-informed about the news?"

Although the Han Dynasty guarded the two most important passes, Longguan and Xiaoguan, it did not mean that they could sit back and relax.

At least Xiaoguan needs special attention.

Because it is located to the east of Longshan Mountain and at the same time it is at the northernmost edge of Longyou.

The big man wanted to support Xiaoguan, but the journey was long and he had to cross Longshan Mountain.

The loss of Yuezhi City caused Xiaoguan to lose an important place of early warning and guidance.

"Hang up the map of Longyou."

Feng Yong suppressed his slightly irritable mood and gave an order.

The staff officer quickly found a map of the entire Longyou and hung it on the wall.

Feng Yong walked to the map, first found the location of Xiaoguan, then clicked on the location of Didao, and finally his eyes fell on the two supporting points of Yuzhong and Jincheng.

"It's impossible to have such good information." Feng Yong said with certainty, "What's going on with the Cao thieves in Liangzhou now?"

"Judging from the news from General Ju, the Cao thieves are indeed as we expected. They only want to stick to the river and Jincheng and have no intention of going south."

Gongsun Zheng quickly replied.

"Then the strange behavior of the Cao thief in Guanzhong is most likely a coincidence."

Such a tacit cooperation cannot be achieved unless we can communicate in real time across the air.

I can't even make a radio. Could it be that you guys have some black technology?

Feng Yong looked at the map closely, playing with the small flag in his hand, and suddenly threw it out, hitting the rare place marked.

It was obvious that he was very annoyed with the bald area.

No matter what the purpose of the Wei army in Guanzhong was, Zhao Yun definitely wanted to return to the east.

If the Battle of Longxi cannot be concluded as soon as possible, once the Wei army in Liangzhou reacts without pressure, it will be its turn to bear the pressure from the north.

If the Bald Ministry can be more successful, Longxi should be ready to clean up the battlefield by this time.

"I want to go to Daxia County myself."

Feng Yong said with determination.

Daxia County is the final point where the Han army arrived in this campaign plan.

When Feng Yong went there, he could see the bald Kheli as quickly as possible and ask what the situation was like in the bald area.

More importantly, he will also look at the specific situation to see how to end this battle as soon as possible and consolidate the results.

Gongsun Zheng had no objection.

At present, the Wei army in Liangzhou has not reacted, and the Qiang and Hu troops in Longxi do not pose a threat to the Han army, so the monarch's trip does not pose much danger.

But he still reminded Feng Yong: "Didao has been decided for the first time, so it is best for the prince to bring his troops with him."

"Three hundred steps are enough." Feng Yong nodded, "Don't worry, I won't put myself in danger."

The unusual movements of the Wei army in Anding County passed through the Longyou Governor's Mansion and were also transmitted to the Prime Minister's Mansion in Hanzhong at an extremely fast speed.

Yang Yi, who was already accompanying Army Commander Shi, hurriedly took the urgent documents that had just been delivered and walked into the hall where the Prime Minister handled government affairs.

"Prime Minister, Longyou sent an urgent letter, saying that there is something strange happening to Cao's bandit over in Anding."

When Zhuge Liang, who was dealing with government affairs, heard this, his expression became condensed and he hurriedly took over the urgent matter.

After reading it, he walked to the huge map hanging on the wall, thought about it for a moment, and finally sighed: "This Cao Zhen is a capable person, and he really shouldn't be underestimated."

Yang Yi followed Zhuge Liang, but she didn't understand why the Prime Minister would utter this exclamation: "Why did the Prime Minister suddenly say this?"

"Guanzhong and Liangzhou are separated by Longyou, making it difficult to communicate with each other."

Zhuge Liang explained, "After the Battle of Longyou last year, the Han Dynasty was temporarily unable to invade Liangzhou. Now both sides have rested for half a year, and it is the beginning of spring, which is the time to use troops."

"Cao Zhen's move can just contain Longyou. Coupled with the loss of Yuezhi City, we have to heavily guard the east and cannot advance westward with all our strength."

Yang Yi asked with some confusion: "Prime Minister, you mean that Cao Zhen has expected that the Han Dynasty will send troops to the west at this time?"

Zhuge Liang nodded, "It's possible, but even if Feng Yong didn't send troops to Longxi, Cao Zhen would probably do this."

"Why is this?"

Yang Yi was even more confused.

"Testing." Zhuge Liang looked at Yuezhi City on the map, his eyes flashing continuously, showing that he was thinking quickly.

"Cao Zhen is most likely conducting a test from Yuezhi City, and at the same time, he is also trying to delay our march into Liangzhou."

After losing Yuezhi City, the Han Dynasty only had Xiao Pass left in the east of Longshan Mountain.

Therefore, Cao Zhen did not hesitate to use troops in winter, in fact, in order to put pressure on Xiaoguan and then support Liangzhou conveniently.

"Because the longer it is delayed, the more advantageous it will be to the Cao thieves. Because Longyou is located between Guanzhong and Liangzhou, there is a danger of being attacked from both sides."

Zhuge Liang figured this out, walked back to his seat, sat down, pondered for a moment, and asked: "Wei Gong, how is the construction of the plank road in the Xiegu?"

Last year, Zhao Yun was discovered by Cao Zhen as a suspected soldier and had to retreat from Xiegu to Hanzhong. At the same time, in order to prevent Cao Zhen's army from pursuing him, he burned the plank road.

It's just that the fire was a bit too big. This fire burned nearly a hundred miles of wooden plank road.

It is easy to set a fire, but difficult to repair it.

The wooden plank road not only needs to wedge wood on the dangerous cliff, but also lay pillars and beams in the water below the cliff for support.

This is a huge amount of work.

"Prime Minister, Zhuge Junjun personally supervised this matter. However, it is difficult to work in winter. Although there is an engineering team from Nanxiang, the progress is still very slow."

"What's more, after the beginning of spring, there will be spring floods and the water flow will be turbulent. I have personally seen it and the red water has surged. Even the thickest logs cannot be fixed into the water."

Yang Yi quickly replied.

From Hanzhong directly to Guanzhong, there are four roads from east to west: Ziwu Valley, Luo Valley, Xie Valley, and Chencang Old Road.

Ziwu Valley is difficult to travel and is full of dangers.

There is another Chencang at the end of Chencang's old road. The terrain is difficult and the army cannot deploy.

The sloping valley is the flattest and can be used by large armies, but unfortunately the plank road is impassable.

"Luo Valley is also difficult to travel. We can only travel with partial divisions, not large armies. It's so difficult!"

Zhuge Liang sighed.

Yang Yi heard the words and knew what he meant, "Prime Minister wants to send troops from Hanzhong?"

Zhuge Liang nodded, feeling a little distressed: "Cao Zhen is testing, we can also feign an attack to cooperate with Longyou. But the sloping valley is blocked, what can we do?"

Yang Yi thought: "Why don't the Prime Minister send people to march from the old road of Chencang?"

"This is the only thing now."

There is no way around it.

After all, if you march from Luo Valley and it is difficult to march a large army, it will be easy for Cao Cao to guess that this is a suspicious army and not the real Hanzhong army.

In that case, it would not be able to contain Guanzhong.

Now Cao Zhen is just testing, so the Hanzhong army cannot be easily mobilized.

Coupled with insufficient preparation, rushing into battle will only waste money and food and tire out the soldiers.

Only by following the old path of Chencang can the Cao thieves believe that it is possible for the army to march into Guanzhong and attack Chencang. It doesn't matter whether they attack Chencang or not. What is important is that at least Cao Zhen cannot act rashly.

Seeing that the Prime Minister agreed with his words, Yang Yi cheered up and continued to suggest: "Last year in the Northern Expedition, the Prime Minister did not listen to Wei Yan's words, and he had little merit in the attack on Longxi."

"Now Wei Yan often complains in private, saying that the prime minister did not use his plans at the beginning and did not allow him to lead the troops out of the Xie Valley, so his ambitions could not be achieved."

"Why don't we let him lead the army out of Chencang Road this time to scare Cao's thieves and prevent him from moaning all the time."

When Zhuge Liang heard Yang Yi's words, he frowned slightly and glanced at Yang Yi.

Yang Yi felt Zhuge Liang's gaze, her heart skipped a beat, and she quickly lowered her head.

"Wei Gong, I know that you and Wei Yan are at odds with each other. It's just that the two of you work for the Han Dynasty, so it is important to attack the thieves together, not to attack each other."

"Wei Gong, you are well-planned. Wei Yan is brave and powerful. They are both rare heroes. If we fight, wouldn't it become a bitter feud?"

Zhuge Liang gave some advice.

Yang Yi did not dare to say any more and quickly agreed.

Zhuge Liang knew that Yang Yi was narrow-minded and not too young, so it was not easy to preach to him.

And this time, although he had selfish motives, what he said did make some sense.

Now in Hanzhong, only Wei Yan is the most suitable to lead the army in this expedition.

It's just that he is a little too careless and eager to make contributions, but he needs to be warned.
