From Taiyuan County, follow the route that General Guan used to raid Hedong, go south, along the Fen River, pass through Xihe County, Pingyang County, and arrive at Hedong.

At this time, in the Hedong Dudu Mansion, Wei Yan went to Shangdang, and Jiang Wei led his troops eastward and stationed in Yize County.

This place, Yize, is a famous place in ancient times.

There is a saying that "Shun plowed Mount Li, made pottery on the riverside, and fished in the marsh", and there is also a record that "the emperor (King Mu of Zhou) rested in the marsh".

There is also a historical record of Tang Tang of Shang Dynasty analyzing Chengshan's prayers for rain and getting a good response, and wrote "Da Yi Le" to celebrate.

Although Jiang Wei is stationed here, he can always turn back and take care of Zhiguan.

But the trend of approaching Gaodu, the northern pass of Taihang County, is already very obvious.

When Feng Duhu learned about this, his expression turned gloomy.

It is indeed not easy for the Han Dynasty to send troops from Hedong to conquer Zhiguan.

The Wei army in Hanoi may not have the courage to leave Zhiguan and enter Hedong.

After all, in flat areas like Hedong, the Han cavalry had a strong advantage.

Especially in the past two years, Yanmen has been trying to find ways to reduce the source of war horses in Youzhou.

Feng Duhu believed that Sima Yi would not dare to collide head-on with the Han cavalry in Hedong without being completely sure.

But this is not a reason to reduce the number of troops defending Zhiguan.

"The so-called controlling the enemy without controlling it means mobilizing the enemy, rather than letting the enemy mobilize himself."

Feng Duhu looked at the map in front of him, slightly annoyed:

"Jiang Boyue moved his army to Yize, seemingly taking care of both ends, but in fact he was caught between them."

"If we are held back by the thieves in Gaodu and cannot escape in time, and the thieves take the opportunity to split their troops and come out from Zhiguan, the east of the river will be in danger."

Wei Yan could not come to greet Feng Duhu, and Jiang Wei was under orders from Wei Yan, so he had no way to get out.

Therefore, the only people who came to greet him were Jiang Bin (son of Jiang Wan), the governor of Hedong, and Shi Bao, Feng Duhu's loyal loser.

Shi Bao's new official position has not yet been appointed, so he is still the general of the Dian Nong Zhonglang.

But he had already heard the news.

After decades of poverty and poverty, he was completely transformed once he met Feng Duhu.

This is no longer a fulfillment of my long-cherished wish, but what I have gained in front of me is already much more than my long-cherished wish.

What is a dog leg?

Even if you are a bitch, it is worth it!

Hearing what Feng Duhu said, Shi Gouji quickly agreed:

"What Zhongduhu said is that the general had such concerns, so he... ahem, it's just that he spoke softly, alas!"

Shibao's virtue may be a bit uncultivated.

For example, he is greedy for money and slightly lustful.

But the talent is indeed outstanding.

Although he secretly reminded Feng Duhu of the anomalies in Hedong in some way, it was suspected of following the trend.

But it is undeniable that his reminder is indeed timely and necessary.

On the contrary, it was Jiang Bin, the governor of Hedong, who had some unpleasantness with Feng Duhu in his early years.

Fortunately, his lord Jiang Wan was the matchmaker when Feng Duhu got married twice, so the relationship between the two in private was quite good.

More importantly, Jiang Bin himself knew that he could become the governor of Hedong precisely because of Feng Duhu's recommendation.

Therefore, the unhappiness between the two of them in their early years has disappeared.

At this time, hearing Feng Duhu's assertion, Jiang Bin opened his mouth to explain:

"The Governor of Wei once said that there is only a river between Hedong and Guanzhong. Even if the general who conquered the east failed to turn back in time, Chang'an could send the imperial army across the river to support Hedong."

Feng Duhu glanced at Jiang Bin, his eyes flashed, thoughtfully.

This statement sounds like an excuse for Wei Yan, but it actually reveals a message:

Wei Yan's transfer not only received the approval of the palace, but may even have received strong support from the palace.

Feng Duhu couldn't help but cursed secretly: Gan!

The Southern Army and the Northern Army, plus a Tiger Cavalry Army, are the three main forces of the Chang'an Forbidden Army.

It is also the cornerstone of stabilizing Guanzhong.

It is also Dahan's strategic mobile reserve force.

Whenever the Chang'an Forbidden Army is to be mobilized, a medium-sized battle is required at the very least.

If the three main forces of the Forbidden Army are all dispatched, then even if it is not a life-and-death moment when the country is in danger, it is still a time to influence a certain direction of the Han Dynasty.

He said that the imperial army could cross the river eastward at any time. If Wei Yan didn't know himself, he would think that the imperial court would give him the truth.

For Feng Duhu now, that can still be regarded as reluctant acceptance.

But if the palace really wants to support Wei Yan, he wants to fight Sima Yi in a medium-sized or larger battle on the old battlefield of the Battle of Changping.

Moreover, it was a coincidence that Feng Duhu was out on inspection and could not get the news in time.

This is the biggest bad news.

Feng Duhu took a deep breath and looked at Jiang Bin:

"In addition to mobilizing troops in Hedong, what about food and grass? Is there any large-scale deployment?"

It doesn't matter if Wei Yan is away, Feng Duhu doesn't want to see that old man anyway.

It doesn't matter if Jiang Wei can't come, Feng Duhu doesn't want to embarrass him now anyway.

But after all, Jiang Bin was the governor of Hedong. Even if he didn't know too much about the military affairs, he still needed the cooperation of the local government on food and logistics matters.

Otherwise, no matter how powerful the Han soldiers are, they cannot go into battle on an empty stomach to kill thieves.

"Except for the requisition of some grain and grass at the beginning, so far, no local grain stocks have been requisitioned."

Hedong is one of the most important counties in the world.

Before the great chaos in the world, Henan was the most important land of three rivers.

But after the great chaos, wars in Hedong were actually less common than in other places.

Therefore, in the land of three rivers, Hedong has become the most populous place.

Even if there is a spring drought this year, there are many rivers in Hedong and it is located on the edge of a large river, so farming is extremely advantageous.

And now that it is under the management of Dahan and has new waterwheels, the impact of drought is naturally much smaller than in other places.

It is precisely because of various reasons that the grain reserves in Hedong have never been small.

Now Wei Yan is mobilizing troops, but there is no sign of requisitioning places to store grain.

This made Feng Duhu a little confused again.

Could it be that this old man really wanted to readjust the defenses in Hedong and Shangdang?

Instead of wanting to send troops?

Feng Duhu rubbed his head with a headache.

Compared to sending troops, this is probably good news?

At most, it could be regarded as Wei Yan's new official's first ignition in taking office, and he wanted to show his sense of presence.

Just hearing what Wei Yan said from Jiang Bin made Feng Duhu feel a little worried.

He let out a long sigh and remembered that when he first arrived in Hedong, there was Jiang Ji on the left, Sima Yi on the right, and Youzhou behind, threatening his retreat, but he could still sit by the river and fish.

I never thought that now that Hedong had returned to the Han Dynasty for several years, I would be so uneasy when I revisited the old place.

"Hedong is the barrier of Guanzhong. If Hedong is damaged, Chang'an will be unstable."

Feng Duhu looked at the two of them and warned:

"Besides, Sima Yi across from you is not an idle person. Please tell General Zhengdong that if anything goes wrong in Hedong, he must report it to Chang'an in time."

There is no hope for Wei Yan.

The prime minister kept Wei Yan by his side during his lifetime. Apart from valuing his bravery, he may not have any intention of keeping an eye on him.

Because Wei Yan has a very high self-esteem, and his temper is too unruly and unruly.

It's okay if someone can suppress him. If no one can suppress him, who knows what will happen?

To put it bluntly, this person is a double-edged sword.

Now that the prime minister is gone, the palace still sends him to the east of the river. Feng Duhu doesn't know whether it is right or wrong.

The purpose of letting Shi Bao join the army as the general who conquered the east was to be sent to Jiang Wei's side so that he could keep abreast of the developments in Hedong.

It's just an insurance policy, of course, but it's more of a psychological comfort.
