Chapter 0977 Nightmare again(1/2)
After the Battle of Xiaoguan, Wei was forced to completely abandon Anding County to the west of Longshan and to the east of Longshan.
Then, defensive fortifications were built around the central area surrounding Yicheng (corresponding to Xiedao) - Chencang (corresponding to Chencang Road) - Qianxian (corresponding to Longguan) - Jingshui Valley in Xinping County (corresponding to Anding County).
As for Feng Thief's little moves in the north of Beidi County and his hometown of Jiuyuan County over the years, Sima Yi was naturally well aware of it.
Therefore, on the one hand, in addition to reversing the practice of shrinking Beidi County since the Later Han Dynasty, he actively eliminated certain pro-Han tribes near Beidi County.
At the same time, the first cordon was set up on the Great Wall within the Qin Dynasty, that is, in the area of Jushui in the north of the original Beidi County (note: it is not Jushui in Hanzhong, it is located in the northern Shaanxi Plateau in later generations).
Beidi County is high in the north and low in the south. If the Shu captives want to raid Guanzhong from the hometown of Jiuyuan, there is a barrier that cannot be bypassed.
This is the Qiaoshan Mountains (later known as Ziwu Ridge).
Qiaoshan Mountains is the collective name for a large mountain range. The altitude of the mountains is not too high, but the terrain is relatively complex.
Even in later generations, it is a well-preserved natural vegetation area on the Loess Plateau and an important ecological forest in the central part of the Loess Plateau.
The Qiaoshan Mountain Range starts from the source of Jushui in the north and ends in Fuping County, the county seat of Beidi County, in the south.
Qinzhidao is in the shape of a zigzag, winding on the ridges of various mountains in the Qiaoshan Mountains.
The army was walking along Qinzhidao, and could overlook all the conditions at the foot of the mountain.
Before the Han Dynasty regained the Hetao area, they relied on this mountain range to prevent the Xiongnu from going south and entering the hinterland of Guanzhong.
It can be said that it is the last barrier in Guanzhong blocking the enemies from the south.
Since the Later Han Dynasty, Beidi County has been shrinking, and its final territory ended at this mountain range.
You can throw it away north of Qiaoshan Mountain, but you can never throw it away at Qiaoshan Mountain.
Therefore, Sima Yi naturally knew the importance of Qiaoshan. He not only had people dig trenches on the Qin Straight Road, but also built barriers to block the cavalry.
At the same time, camps were set up at various dangerous mountain passes in Qiao Mountain, intending to set up camp step by step to stop the enemy.
And because the mountains south of Qiaoshan end in Fuping County, the county seat of Beiji County, there are many rivers of different sizes that converge from the mountains and flow through Fuping County.
The dense river network, as long as it is used properly, can also delay the advance of the cavalry. This is Sima Yi's third line of defense.
It can be said that Sima Yi attached more importance to the defense of Beidi County than anyone imagined.
He would not leave the slightest chance for his opponent to raid Guanzhong from Beidi County.
There was no way, the Ghost Cavalry under King Feng Gui was really too terrifying. If they were allowed to cross the Qiaoshan Mountains and enter the Guanzhong plains, no one would be able to say that they could withstand the charge of the Ghost Cavalry.
If the Han army wanted to imitate Huo Piao and Yao and make a large circle from the desert and go south along the Qinzhi Road, they would have to attack his camps one by one on the tops of Qiao Mountain.
The problem is... the enemies coming from Jiuyuan's hometown must only be cavalry.
How much casualties would the cavalry have to pay to capture these densely packed camps or the camps placed in dangerous passes on the mountain tops?
Naturally, Feng Yong didn't know about Sima Yi's arrangements.
So he didn't know that after leading the army in a big circle this time, he would most likely run into the hardest turtle shell at some point in the future.
Just when he was having a great time leading the sheep in the desert, Xi Zuo of Wei State in Hanzhong and Longyou was already running like flying through the deep mountains and old forests of Qinling Mountains and Longshan Mountains.
They walked on the wild paths in the mountains that only woodcutters knew, and wanted to convey the news of the Han army's dispatch to Guanzhong as quickly as possible.
But it was Xicheng who first conveyed the news.
Although the Shu people used the excuse of not traveling for a long time on business trips, they blocked several roads in Hanzhong two years ago.
However, as the Xiegu Road where Shu captives in Hanzhong are most likely to appear - the other road is Chencang Road - Xicheng's outposts placed on the Xiegu Road have never been interrupted.
The outposts detected that there seemed to be abnormal Shu captives deep in the Xiegu Road. Coupled with the sudden closure of the Longshan Pass to prevent business travelers from traveling, Sima Yi suddenly guessed what might happen.
When the secret agent in Shu sent the first information to Chang'an, Sima Yi confirmed the authenticity of the information on the spot.
"Pass my order to Xicheng to send additional sentinels to find out the movements of the Shu captives!"
Sima Yi made a "pop" sound, pressed the silk with urgent military information on the case, and said sternly.
"Here!"
"Come here and send an order to Qianxian and Chencang, asking them to step up their defenses and guard against any loss!"
"Here!"
After giving the instructions, Sima Yi suddenly let out a long breath, relaxed his whole body, and murmured with a vague light in his eyes:
"finally come!"
Everyone knows that the Shu captives, who have great geographical advantages, will invade Guanzhong sooner or later.
Years of preparation, waiting for today.
If this battle is defeated, the Wei Dynasty will completely lose the opportunity to unify the world.
On the contrary, if the Shu captives can be defeated in this battle, Longyou can be restored.
With Longyou in hand, Liangzhou will have no worries.
Just when Sima Yi regained his energy and was about to issue the third military order, suddenly there was a dull and loud noise in the distance.
The loud noise sounded like thunder but not thunder, and there were gold-like objects striking each other.
When Sima Yi heard this voice, his heart skipped a beat, as if he remembered something, he quickly ran to the door and looked in the direction of the voice.
But the sky was clear and the sun was high, but there was no sign of thunder.
Sima Yi's face was slightly gloomy, because the loud noise was coming from the direction of Tongguan.
"Go, send someone out of the city to see what happened."
He turned around and ordered the personal guards who were following closely.
"Here."
Back in the house, Sima Yi was alone in a room, with a look of hesitation on his face, as if he was thinking about something.
Although it is almost certain that the Shu captives will invade in a large scale, it is still unknown where the main direction of the Shu captives' invasion will be from Ziwu Valley in the south of Chang'an to Qiaoshan in the north.
So he was not in a hurry to mobilize his troops.
Because there's no point in being anxious.
Only by knowing in which direction the Ge thieves and Feng thieves appeared can the Guanzhong army be mobilized in a targeted manner.
The Ge Thief will most likely come out of Xiegu. After all, there are several roads in Hanzhong, and this is the best way to go.
Even Chen Cangdao is not a good choice.
Because the deep valley below the Dashanguan Pass is very steep, with cliffs confronting it on both sides, like a line of sky.
Unless a sneak attack is successful, only a few thousand defenders are enough to make it difficult for tens of thousands of troops to move forward.
Even though it is rumored that the Shu captives have powerful siege weapons, it is not so easy to capture the narrow pass.
Therefore, Thief Ge's actions are easy to guess, but Thief Feng...
When Sima Yi thought of this thief, he suddenly felt a little irritable.
If Ge Ze likes a master who is upright and uses his power to force others, then Feng Ze is erratic, full of tricks, and unpredictable.
But this thief is very good at attacking, so people have to be careful.
Longguan?
Xiao Guan?
stable?
Or...Northland County?
Just as Sima Yi was thinking about it and anxiously waiting for more information from the details and the sentinels, a sergeant came hurriedly from outside to report:
"Da Sima, it's too bad. The people's manpower is insufficient. The dew-bearing tray had only been transported for about thirty miles when it fell into the trench and broke!"
Sima Yi's head buzzed, and he lost his voice: "What?"
It turns out that the loud noise in front was caused by the dew plate breaking?
Sima Yi's face changed drastically, and he suddenly slapped his thigh: "The Shu captives invaded, I actually forgot about it!"
He made a trip to Luoyang the previous time and argued hard, so that His Majesty knew that transporting the Jinren and the Bearing Tray at the same time would excessively deplete the people of Guanzhong, which would not be conducive to strengthening the defense of Guanzhong.
Therefore, you can transport the dew plate first this year, and then transport the gold person next year.
Although the dew tray is much larger than the Jinren, it can be disassembled.
Just moving it is still very difficult.
Thirty thousand civilians paved roads, built bridges, and worked hard to carry the goods. On flat land, it could only cover ten miles a day, but on rugged land, it was common for them to move three or four miles a day.
So for more than a month, we demolished and moved again, and then we moved the dew-bearing plate about thirty miles out of Chang'an City.
Unexpectedly, when it was first discovered that the Shu captives were invading, the dew plate fell into the trench and broke, and its sound could be heard for dozens of miles.
Sima Yi's face suddenly darkened.
He just said, "I actually forgot about this," which of course was not the truth.
He was originally waiting for the situation to be truly clear tomorrow or the day after tomorrow, so that he could have a reason to report to His Majesty and stop carrying the dew tray.
To be continued...
