Everyone was startled when they heard this. They seemed to have never thought of the retreat plan proposed by Cao Liang. After all, the Wei army's offensive route this time was the Tangluo Road, so subconsciously, when the Wei army retreated, they should also take this route.

This is the way.

Therefore, the Wei army made a desperate move and concentrated its superior forces to attack Fenshuiling, Shenling, and Yaling occupied by the Shu army, trying to carve out a passage from there and return to Guanzhong.

But now that the watershed has repeatedly failed to be conquered, and the Wei army's return journey has been intercepted, everyone has fallen into pessimism and despair. It seems that if they cannot recapture the watershed, the Wei army will be trapped and die here.

Cao Liang's words seemed to open another door for everyone, and everyone suddenly realized, yes, why do they insist on the watershed and the Tangluo Road? This road is blocked, can they find another way? From Hanzhong to the north, they can reach Guanzhong

, and heading east from Hanzhong, you can reach the three counties of Shangyong, Fanling and Wei Xing. Like Guanzhong, these three eastern counties are also the territory of the Wei Dynasty. As long as you can reach there, the Wei army can also escape from danger.

Dongsanjun is relative to Hanzhong. It is located to the east of Hanzhong, so it is called Dongsanjun. When Liu Bei and Cao Cao competed for Hanzhong, Cao Cao was defeated. Hanzhong belonged to Liu Bei, and Liu Bei ascended the throne as King of Hanzhong. Taking advantage of the great momentum,

At the right time, he sent Liu Feng Mengda to lead his troops to capture Dongsan County.

Later, Jingzhou fell. Because they sat back and watched Guan Yu's defeat without sending troops to aid, Liu Feng was killed by Liu Bei, and Meng Da surrendered to the Wei State. From then on, the three eastern counties belonged to the Wei State.

Later, the capricious Meng Da decided to rebel against Wei and return to Shu because he was not taken seriously in the Wei state. However, after the news was leaked, he was caught off guard by Sima Yi who came all the way at starry night. Meng Da was captured alive and cut in half in Luoyang.

, the Shu people will never have the chance to get involved in the three eastern counties again.

Although Dongsan County is adjacent to Hanzhong, the two sides have been living in peace for a long time. Compared with the war-torn Yongliang front line, this place is extremely quiet and like a paradise.

The only time that troops were used was during the Wei State's three-pronged expedition against Shu. Sima Yi led his troops from Xicheng and went up the Han River. However, due to heavy rain, the road was cut off, so the Wei army retreated early without engaging in a battle.

A few days ago, Jiang Wan, the Great Sima of Shu State, had planned to march eastward by waterway, but due to various reasons, the plan was shelved.

Therefore, the two countries of Wei and Shu have never fought on the border of Dongsanjun. This is not to say that both sides have not thought about it, but because the geographical conditions here are too harsh and are not suitable for large-scale legions.

Combat.

From the terrain point of view, the terrain from Hanzhong to the three eastern counties is a slowly descending terrain. For the Wei State, going up the Han River to attack Hanzhong is an attack from above. This kind of attack can be said to be the most difficult to attack.

A kind of battle.

As for the Shu Kingdom, it is easy to go out but difficult to return. It is relatively easy to go back down the Han River, but if the war is unfavorable, it is extremely difficult to go back against the current. During the Battle of Yiling, the Shu army

It was defeated by Lu Xun because of the difficulty in returning, and almost the entire Shu army was destroyed.

Therefore, during the Northern Expedition, Zhuge Liang preferred to go further to Qishan Mountain instead of the shortcut to the Three East Counties. The main reason was to avoid repeating the mistakes of the Battle of Yiling.

It was precisely because there was little fighting along this route that the generals of the Wei army did not realize that there was an escape route here.

It may not be a good idea to attack Hanzhong and take the three eastern counties, but it is different now. They want to find a retreat. No matter whether it is difficult or easy, as long as they can leave Hanzhong safely, everything will be fine.

The people of the Wei army who were already in a desperate situation were now excited and their confidence was rekindled. They gathered in front of the map, pointing and planning the retreat route.

At this time, Guo Huai coldly poured cold water on everyone: "Cao Changshi, your fantastic ideas are wonderful, but in fact they are just drawing cakes to satisfy your hunger. If you want to take the east road, you must break through the golden fortress."

, do you know what kind of city Golden Gate is like?"

Everyone shook their heads one after another. Huangjinwei was indeed quite unfamiliar to them.

Guo Huai said to Cao Liang: "Does Cao know the history?"

Cao Liang said frankly: "Unknown."

Guo Huai sneered and said: "Since Cao Changshi knows nothing about the Golden Siege, how dare he boldly persuade the general to go to the three eastern counties? Don't you want to put all the troops to death?"

Cao Liang immediately retorted: "Then Governor Guo has been to Jinjin?"

Guo Huai raised his head and said: "Although I have not come in person, I have already sent people to inquire about the situation of Huangjinwei and drew a geographical map. I can tell you responsibly that the difficulty of attacking Huangjinwei is not at all.

It is inferior to the watershed, or even worse. After all, Huangjinwei is a fortress that has been built for many years, while the watershed is just a temporary battlefield. There is no comparison between the two."

After hearing what Guo Huai said, everyone couldn't help but feel a chill in their hearts. Even Cao Shuang looked disappointed.

A small watershed can block the Wei army's retreat due to its danger. What's more, a strong city fortress like Huangjinwei not only has a dangerous terrain but is also well-defended. You can imagine how difficult it would be for the Wei army to overcome it.

Huangjinwei is east of Xingshi and west of Wei City. The Han River bends a huge arc here. The ninety-mile Huangjin Gorge is called the first gorge of the Han River. It is full of dangerous shoals and the river flows rapidly. The Huangjinwei

It is built in a dangerous part of the canyon.

Huangjinwei was built in the late Eastern Han Dynasty. When Zhang Lu separatized Hanzhong, in order to prevent the invasion of powerful enemies, a pass was built at the most dangerous point of Huangjin Gorge, which contributed greatly to Zhang Lu's long-term separatist rule in Hanzhong.

During the stalemate between Wei and Shu, Golden Siege became a fortress for the Shu State to defend against the Wei State's attack, and garrison troops have been stationed here.

The Wei army's attack on Hanzhong this time took the Tangluo Road, so they bypassed Huangjinwei and directly reached the Xingshi west of Huangjinwei. The role of Jinjinwei in defending the Wei army was not effective, and the Wei army's target was Hanzhong. Naturally,

He also ignored Huang Jinwei, so the two sides have always been at peace with each other.

However, if the Wei army wants to retreat from the three eastern counties this time, it must pass through Huangjinwei. Only by occupying Huangjinwei can it be possible to clear the way for retreat. Otherwise, the Wei army is likely to be trapped and die in Xingshi Mountain.

The army was destroyed.

Cao Liang did not lose heart because of Guo Huai's cynicism. Although he did not understand the defense situation of Huangjin, Cao Liang firmly believed that there was no end to the road. No matter how dangerous the Golden Siege was, there would always be a way to win it.
