Seoul was originally known as Chuyang, but it was a small county town adjacent to Hanshui, but after Zhuge Liang determined the defense system of Hanzhong, Hancheng also jumped from a small city with no name to a top fortress city in Hanzhong, and together with Lecheng (Chenggu), it became one of the twin constellations on the defense chain of the Han army.

On the contrary, the original Hanzhong County seat in Nanzheng fell at the end, in the defense system of the two cities of Hanle, there was no existence of Nanzheng, and after Wang Ping retreated from Xingshi this time, they only defended Hancheng and Lecheng.

Wang Ping handed over the defense of Lecheng to Liu Min, and he led more than 10,000 Wei troops to retreat to Seoul.

This is the last defense system of the Shu army in Hanzhong, if Hancheng is lost, it is equivalent to the complete fall of Hanzhong, so no matter how difficult the situation is, Wang Ping gritted his teeth and insisted.

The fall of Xingshi made Wang Ping sleep, at this time to retreat to Seoul, he knew his responsibilities, so even if the Wei army surrounded the city, Wang Ping did not waver, he was determined, swore to live and die in Seoul, even if he fought to a soldier, as long as there was half a breath, he would never let the Wei army easily enter the city.

This is not Wang Ping's rhetoric, but he warned himself in his heart that no matter what, he will fight to the end.

The Wei army also regarded this place as the main battlefield, the general Cao Shuang, and the general Xiahou Xuan of the expedition to the west were all here, and the Wei army set up a large camp in the south of the city of Hancheng, across the Han River and Hancheng far away.

Since the first day of the siege, the siege has not stopped, but since the defense of Seoul has been carried out for more than 20 years, it is certainly not so easy to overcome.

Cao Shuang also understood that Seoul and Lecheng were two hard bones to bite, and if they wanted to take these two rock-solid cities, the Wei army used many siege equipment such as catapults, but they also had little effect.

The general idea of the battle of Hanzhong was to stick to the outer positions of Hanzhong to block the reinforcements of the Shu army, and the two cities of Hanle in Hanzhong were slowly planned.

But first of all, the periphery must be able to be defended, there are Xiahou Ba and Cao Liang on the side of Yangping Pass, and it is naturally no problem to hold on, but the newly emerging Dingjun Mountain has become the last straw that overwhelms the camel.

Sima Zhao and Guo Huai failed to hold Dingjun Mountain, causing Jiang Wei's reinforcements to enter the Hanzhong Plain in an instant, completely disrupting Cao Shuang's deployment at once, and the situation in Hanzhong was already completely collapsed and out of control.

After Jiang Wei entered Hanzhong, he did not rush to use troops in the second city of Hanle, but wandered outside the second city, and encroached on the small scattered troops of the Wei army, and his movements were extremely fast, basically changing places with one shot, and some of the small troops of the Wei army were surrounded by Jiang Wei's army without even reacting.

There was almost no suspense in such a battle, and even the time of resistance was very short, and it was a completely one-sided massacre.

Some Wei troops found that the situation was not good, and wanted to escape from the garrison and join the main force, but Jiang Wei was faster than them, and basically made a prediction in advance, and sent troops to intercept the route that the Wei army wanted to escape, so that those who were encircled by the Wei army were basically unable to fly and were slaughtered by the Shu army.

Jiang Wei pursued the tactics of each break, and the dispersion of the Wei army's forces undoubtedly provided Jiang Wei with an excellent opportunity, those small troops stationed out became Jiang Wei's dishes, Jiang Wei rushed back and forth, it only took a day or two to eat four or five small units of the Wei army, the number of people ranged from 1,000 to 3,000 or 4,000 people, but in total, it also exceeded 10,000 people, and the Wei army suffered heavy losses.

The main reason why Jiang Wei did not move the Wei army camp in Seoul for the time being was that his own troops were insufficient, although Wang Ping's army was used as internal support, but if he wanted to shake the main force of the Wei army, at least Fei Yi's army had to come.

Jiang Wei still has a clear understanding of this, after the Dingjun Mountain defense line is broken, the defeat of the Wei army is already doomed, the difference is how many Wei troops the Shu army will eat.

If the Wei army reacts quickly, it will shrink its forces together in time and not give the Shu army a chance to break through, so that the cost of casualties of the Shu army will be minimal, and the worst can ensure that the whole division retreats.

However, the Wei army's forces in Hanzhong were too scattered before, so after encountering this unexpected situation, they were a little slow to deal with it, and more than 10,000 people were eaten by Jiang Wei.

Whether it is Cao Shuang or Xiahou Xuan, they are both military book generals, they have been familiar with military books since childhood, but they lack actual combat experience, such a person is naturally handy in fighting against the wind, but in fighting against the wind, the situation is not so good.

The emergency documents flew like snowflakes everywhere, and Cao Shuang had a big head for a while, and he was at a loss, and he didn't know what to do.

Although Xiahou Xuan is stronger than Cao Shuang, it is difficult for him to make a decision in this chaotic situation.

The Wei army in Seoul has been besieged for a long time, although it has not been able to break the city, but it has already consumed a lot of defensive forces in the city.

But now that the city has not been broken, the enemy's reinforcements have arrived, and the Wei army will bear the crisis of being attacked by the enemy on its belly and back, and if it is not handled properly, it is very likely that the whole army will be destroyed.

Therefore, Yang Wei, who joined the army, proposed to immediately withdraw the siege of Hancheng and join the Wei army in the Lecheng camp to the east to avoid being broken by the Shu army.

Cao Shuang had no choice but to follow Yang Wei's advice and retreat the Wei army camp to the east, heading to Lecheng to join up with another Wei army.

As for the Xiahou overlord army in Yangping Pass, due to the distance, it was already beyond the reach of the whip commander, Xiahou Xuan sent people to inform them to evacuate, but the people sent out were intercepted by the Wei army on the way.

Jiang Wei was extremely interested in this letter, the withdrawal of Cao Shuang's army Jiang Wei did not stop it, with only his existing troops, it was difficult to leave Cao Shuang.

However, the Wei army withdrawn from Yangping Pass became the target of Jiang Wei's hunting, since they came to Seoul, Jiang Wei was ready to hold a welcome feast for them in Seoul to entertain these "distinguished guests".

During the battle of Yang'an Pass, the Wei army relied on the danger of the city, which made Jiang Wei suffer a lot, and he came and did not be rude, this time Jiang Wei finally seized the opportunity, he discussed with Wang Ping, laid a net, and waited for Xiahouba and Cao Liang to drill.
