Everyone was stunned when they heard this, they didn't seem to have thought of this retreat plan proposed by Cao Liang in advance, after all, the Wei army's offensive line this time was Fu Luo Dao, so subconsciously, when the Wei army retreated, it should also take this road.

Therefore, the Wei army made a desperate bet, concentrated its superior forces, and stormed the watershed, Shen Ridge, and Yaling occupied by the Shu army, trying to make a passage from there and return to Guanzhong.

But now the watershed has been repeatedly attacked, the Wei army's return path has been intercepted, and everyone has fallen into pessimism and despair, as if they feel that if they can't 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 immediately realized, yes, why are they obsessed with the watershed, obsessed with Fu Luo Road, this road is not passable, can you find another way, from Hanzhong to the north, you can reach Guanzhong, and from Hanzhong to the east, you can reach the three counties of Shangyong Fangling Weixing, and Guanzhong, these three eastern counties are also the territory of the Great Wei, as long as they can get there, the Wei army can also get out of danger.

The three eastern counties are relative to Hanzhong and are located in the east of Hanzhong, so they are called the three eastern counties. Liu Bei and Cao Cao competed for Hanzhong, Cao Cao was defeated, Hanzhong belonged to Liu Bei, Liu Bei was promoted to the king of Hanzhong, and took advantage of the momentum to send Liu Feng Mengda to lead the troops to capture the three eastern counties.

Later, Jingzhou was lost, because he sat back and watched Guan Yu's defeat and did not send troops to help, Liu Feng was killed by Liu Bei, and Meng Da surrendered to Wei, so the three eastern counties belonged to Wei.

Later, the capricious Meng Da decided to raise troops against Wei and return to Shu because he was not valued in the Wei State, but after the news leaked, he was caught off guard by Sima Yi, who came from the starry night and Cheng Dao, Meng Da was captured alive and beheaded in Luoyang, and the Shu people never had the opportunity to get involved in the three eastern counties again.

Although the three eastern counties are adjacent to Hanzhong, for a long time, the two sides have been peaceful, and compared with the war-torn Yongliang front, it is quiet and unusual, like a paradise.

The only time the troops were used was when the Wei State attacked Shu on three roads, Sima Yi led the troops from Xicheng and traced the Han River up, but because of the heavy rain in the sky, the road was cut off, so the Wei army withdrew early before the battle.

A few days ago, Sima Jiang Wan, the great master of Shu, had planned to go east by water, but due to various reasons, the plan was finally put on hold.

Therefore, the two countries of Wei and Shu have never fought on the border of the three eastern counties, not because the two sides have not moved their minds, but because the geographical conditions here are too bad to be suitable for large-scale army operations.

From Hanzhong to the three eastern counties, in terms of topography, it is a kind of terrain that descends slowly, for Wei, tracing the Han River to attack Hanzhong, that is the upward attack, this kind of attack can be said to be the most difficult kind of battle.

For Shu, it is easy to go out and it is difficult to return, and it is easier to go down the Han River, but once the war is unfavorable, it is extremely difficult to go back. At the time of the Battle of Yiling, the Shu army was broken by Lu Xun, and because of the difficulty of returning, the Shu army was almost completely annihilated.

Therefore, during Zhuge Liang's Northern Expedition, he would rather go to Qishan and give up the shortcut of the three eastern counties, the main reason is to avoid repeating the mistakes of the Battle of Yiling.

It was precisely because of the neglect of the war on this route that the generals of the Wei army did not realize that there was still a way to retreat here.

It may not be a good strategy to attack Hanzhong and go to the three eastern counties, but now it is different, they are looking for a way out, no matter how difficult it is to walk, as long as they can leave Hanzhong safely, everything will be fine.

The Wei army, which was already in a desperate situation, rejoiced at this moment, and their confidence was rekindled, and they gathered in front of the map, pointing and planning the route of retreat.

At this time, Guo Huai coldly poured a basin of cold water on everyone: "Cao Changshi, your whimsical idea is wonderful, but in fact it is just a painting cake to satisfy hunger, if you want to take the east road, you must break through the gold encirclement, do you know what kind of city the gold is encircled?" ”

Everyone shook their heads one after another, and Huang Jinwei was indeed quite unfamiliar to them.

Guo Huai said to Cao Liang: "Do you know Cao Changshi?" ”

Cao Liang said frankly: "Unknown. ”

Guo Huai sneered: "Since Cao Changshi doesn't know anything about the Golden Siege, how dare he unashamedly persuade the general to go to the three eastern counties?" Don't you want to put your armies to death? ”

Cao Liang immediately retorted: "Then Guo Tingshi has been to gold?" ”

Guo Huai raised his head and said: "Although I have not been there in person, but what is the situation of the Golden Siege, I have already sent someone to investigate, and there is a geographical map, I can tell you responsibly that the difficulty of attacking the Golden Siege is no less than the watershed, or even more than that, after all, the Golden Siege is a fortified fortress that has been built for many years, and the watershed is just a temporary battlefield, and there is no contrast between the two." ”

Listening to Guo Huai's words, everyone's hearts couldn't help but feel cold, and even Cao Shuang showed disappointment.

A small watershed, with the danger can block the retreat of the Wei army, not to mention such a fortified fortress as Jinjinwei, not only the terrain is dangerous but also well-prepared, the Wei army wants to overcome, the difficulty can be imagined.

The Golden Gorge is in the east of Xingshi, the west of the West City of Weidi, the Han River folds a huge arc here, the Golden Gorge of 90 miles, known as the first gorge of the Han River, the dangerous shoals are numerous, the river is turbulent, and the Golden Siege is built in the dangerous place of the canyon.

The Golden Siege was built in the late Eastern Han Dynasty, when Zhang Lu divided Hanzhong, in order to block the strong enemy from attacking, he built a pass at the most dangerous place in the Golden Gorge, and made a contribution to Zhang Lu's long-term secession of Hanzhong.

By the time of Wei and Shu's stalemate, Jinjinwei became a fortress for Shu to defend against Wei's attack, and defenders have been stationed here for a long time.

The Wei army attacked Hanzhong this time, because it was Fu Luo Road, so it bypassed the Golden Siege and directly arrived at the prosperity of the west of the Golden Siege, the role of the Golden Siege to defend the Wei army did not play, and the Wei army's target was Hanzhong, so naturally they also ignored the Golden Siege, so the two sides have been peaceful.

However, if the Wei army wants to retreat from the three eastern counties this time, it must go through the Golden Siege, and only by occupying the Golden Siege can it be possible to open up the way to retreat, otherwise, the Wei army is likely to be trapped and killed in Xingshi Mountain, and the whole army will be annihilated.

Cao Liang was not discouraged because of Guo Huai's cynicism, although he did not understand the defense of gold now, but Cao Liang firmly believed that there is no endless road, even if the gold siege is dangerous, there will always be a way to take it.

"It's man-made. The general, the last general, asked for orders to attack the gold and fight a way out. Cao Liang's eyes were firm, and he took the initiative to ask Cao Shuang for his life.
