Since the Wei army had abandoned almost all the cities west of Chang'an, the advance of the Shu army could be described as unimpeded.

The Shu army marched in two ways, Liu Yin led the front army, the middle army and the left army from Chencang, along the Weishui eastward, until the western suburbs of Chang'an, Liu Zhan led the right army and the rear army from Anding, along Jingshui to the southeast, and Liu Yin met under the city of Chang'an.

Because of the lack of troops, in order to prevent being broken by each one, Sima Wang gave up Huaili, Wugong, and Meixian to the west of Chang'an, and Chiyang and Xinping cities to the northwest, and concentrated all his troops in Chang'an, and put on a posture of defending Chang'an.

It can be said that Sima Wang's move was also forced to be helpless, when he first arrived in Guanzhong, Sima Wang had 100,000 troops, and put on an aggressive offensive posture, perhaps at that time, Sima Wang did not consider the defense of Guanzhong at all, he focused more on how to capture Longxi, and all strategic arrangements were also formulated around attacking Longxi.

However, after the Battle of Jieting, Sima Wang had to switch from offensive to defensive and redeploy the defense system in Guanzhong. At that time, the defense strategy adopted by Sima Wang was a comprehensive defense system, which kept the enemy outside the country, and divided the entire defense system into two lines, north and south, with Chang'an as the center and Chencang and Xinping as the defense points, to build a complete defense system in Guanzhong.

The core of this defense system is to fight each other, fight for every inch of land, and use Chen Cang and Xinping to hold the passage into Guanzhong and keep the Shu army out of Guanzhong.

But the disadvantage of multi-point defense is that the battle line is too long, and it is easiest to be broken by the enemy individually. Liu Yin took advantage of this weakness of the Wei army's defense line, and first adopted the strategy of attacking the east and the west, inducing Sima Wang's main force to come to Xinping to help. Then the main army smashed directly into Chencang, forcing Sima Wang to turn around and go south again, and so on, the Wei army must be exhausted. Later, Liu Yin used the strategy of besieging the city to send reinforcements, set up an ambush in Wuzhangyuan, annihilated Sima Wang's main force, and forced the defenders of Chencang to disorganize themselves. So as to take the old warehouse lightly.

The loss of Chen Cang caused the defense line of Guanzhong, which Sima Wang had painstakingly managed, to collapse in an instant, and Sima Wang, who suffered heavy losses, was forced to change his defensive strategy and defeat the comprehensive defense as the key defense. The forces were concentrated in Chang'an City, and the cities outside Chang'an were completely abandoned.

This is also Sima Wang's most pragmatic strategy, if the plan of multi-point defense is continued, then the distribution of forces of the Wei army is a major problem. It is easy to be broken by the Shu army.

And so it goes. The defense of Chang'an has been strengthened, but the west of Chang'an has become an undefended place, and the two armies of the Shu army are driving straight in, but it has only been two days, and the troops have already arrived under the city of Chang'an.

After Liu Yin led the army to the western suburbs of Chang'an, he did not directly attack Chang'an City, but began to clean up the outer counties of Chang'an, forming a siege of Chang'an, and at the same time wanted to lure the Wei army out of the city to fight.

However, Sima Wang ate the scales this time. No matter how Liu Yin tosses outside Chang'an City, he just guards Chang'an City and does not send troops.

After Sima Wang shrank his forces. These suburbs of Chang'an almost became empty cities, the Shu army effortlessly captured several cities one after another, the South Route Army swept Yunxian, Lantian, Duling, Xinfeng, the North Route Army swept Anling, Yangling, Changling, Gaoling, and finally the North and South Road armies met with Baling Bridge, completed the division of Chang'an.

However, no matter how Liu Yin deliberately put on a flaw, Sima Wang just didn't fight, the nine gates of the entire Chang'an City were closed, and the suspension bridge was hung high, which made Liu Yin's plan to lure the enemy fail. It seems that Sima Wang has already suffered enough from Liu Yin, and this time he will not be fooled.

"Wenxuan, since the army was dispatched to Nanzhong in August last year, it has only been half a year, and we have already been in Chang'an City, this situation is really like a dream." Liu Chen looked at Chang'an, which was once the capital of the former Han Dynasty, and sighed sincerely.

The expedition to the Northern Expedition, is indeed brilliant, only half a year, the Shu army has swept the entire Yongliang region, is already far beyond the ancestors of the record, even if there is a talent of the heavens and latitudes of Zhuge Liang, there is no chance to witness the city wall of Chang'an City, but Zhuge Liang's grandson, followed Liu Yin all the way to play a triumphant song, and now it is already a soldier under Chang'an City, from the original Zhuge Liang to restore the Han Dynasty, back to the old capital of the dream, really only one step away.

Under the city of Chang'an, this is the dream of countless Shu people, but in the era of the strongest national strength of Shu, this is also an unattainable luxury, Zhuge Liang's success and failure again and again, so that the enthusiasm in the hearts of Shu people is extinguished little by little, and there is no hope to be seen, and Chang'an City has become the most distant place in the minds of Shu people.

After the death of Zhuge Liang, the Shu Han people of all the people understood that the so-called restoration of the Han family was returned to the old capital, which has become a bubble, although Jiang Wei sent troops to the Northern Expedition again and again, but no one agreed that he could surpass Zhuge Liang's achievements, and the facts also proved that Jiang Wei's efforts again and again were fruitless, but the national strength of Shu was empty, giving the Wei people the opportunity to attack.

At the critical juncture of the overthrow of the Shu State, Liu Yin provoked the heavy burden of reviving the Han Dynasty, and he took a surprise army in a way that ordinary people could not imagine, and realized a strategic detour, not only to take the six counties of Longshang, but also to break the Wei army of 100,000 horses, and the soldiers came to the city of Chang'an.

Such a counterattack battle, it is no wonder that Liu Chen, the king of the northern land, is like a dream, until now, he still has an unreal feeling, saying that the Shu Han Dynasty is at the end of the road, but after half a year, he killed the city of Chang'an, and put thousands of miles of Guanlong land into the bag, this is simply a stroke of genius!

Liu Chen can't help but admire Liu Yin is the five-body throw, think that others dare not think, do others dare not do, Liu Yin is stunned to kill a way in a desperate situation, although this road is full of thorns, although this road is full of blood and tears, but to this point, Liu Yin is undoubtedly successful, his achievements are ancient and modern, no one can match.

In the face of Liu Chen's praise, Liu Yin just smiled modestly, every step he took was a dance of the tip of the knife, wandering in danger and danger, and every step was not allowed to have the slightest deviation, even if it seems to be infinite now, in fact, it is also a crisis, one wrong step, all the games are lost, so Liu Yin has never relaxed, every step is cautious, and the calculation is exhaustive, Chang'an is only a part of his layout in the world, which is a relatively heavy part.

Now is not the time to praise the merits, Liu Yin has also heard a lot of praise, naturally he didn't take it to heart, he put more thoughts on the need to take Chang'an City as soon as possible. (To be continued.) )
