Chaos of the Three Kingdoms Summons

"If you want to enter the hinterland of Hanzhong, several roads are cliffs, rugged and difficult!"

Then, Feng Yi introduced the situation of the road from Yongliang to Shu for everyone.

The first Tangluo road, to take this road from the south of Chang'an, you must first pass through the Xiluo Valley of Zhouzhi County, and then pass through the Xiluo Valley Water, Heishui, Yushui, Youshui, Tangshui and other river valleys, and cross the Xiluo Valley Water and Hei There are four or five mountains, including Shibapanling between the waters, the main ridge of the Qinling Mountains between the Heishui and the Yushui, the Xinglong Ridge between the Yushui and the Youshui, and the Niuling and Guanling Liang between the Youshui and the Tangshui. big mountains.

Compared with the remaining roads, although the Tangluo Road has the advantage of being a short and fast route, the mountains to be crossed on the way are much higher than the other roads, and the road is extremely difficult and dangerous.

The Shibapan and Laojunling mountains near Luoguguan are steep. The road from Laojunling to Dudumen winds among the tributaries of the Heihe River on the south side of Taibai Mountain, the main peak of the Qinling Mountains, and rises and falls in the primitive forest with few people and wild animals. .In Zhenfu County of Yangzhou, there are 84 pans with a bend of 84 miles. Not only are there "extremely lingering fences and endless dangerous stacks", but also a dangerous place called "Yellow Spring".

It can be said that compared with other roads, this road is the closest.However, the sinisterness in it is also more than three points.

The second Baoxie Ancient Road starts from Baogukou in the south, ends at Xiegukou in the north, runs along the Baogu River and Xie River, and runs through the entire Qinling Mountains. It is about [-] miles long and avoids many dangerous peaks. Better to go the valley road!

In the past, King Wen of Zhou traveled to Bashu through the ancient Baoxie Road. Later, during the Warring States period—King Zhaoxiang of Qin Dynasty, he used a lot of manpower and material resources to lay the valley road on the cliffs and cliffs passing by. The plank road, known as "a thousand miles of plank road, can lead to everything", has firmly controlled the Bashu area!

The third ancient road, also known as 'Chencang Road', runs from Guanzhong-Chencang to Dashanguan in the southwest, along the valley road in the upper reaches of the Jialing River, turns southeast into Baogu, and exits the valley to the hinterland of Hanzhong.

In the past, Liu Bang was named the King of Han, unwilling to live in Bashu, he worshiped Han Xin as a general, built plank roads, and secretly guarded Chen Cang. The army entered Guanzhong through this road, wiped out the "Three Qin Kings" in one fell swoop, and competed with Xiang Yu in the east!
As the main road to Shu, Liu Che was also the most prepared for Chencang Road.Besides, when the ancestors made their fortunes, they left a strong mark on this ancient road.There is such a historical reason that it is normal for Liu Che to pay more attention to this ancient road.

The fourth road, Ziwu Road, is named because it crosses the Ziwu Valley and runs north-south from Chang'an southbound.

After Liu Bang, Emperor Gaozu of the Han Dynasty, went to Hanzhong and sent Zhang Liang to burn the Ziwu plank road, in the fifth year of Emperor Ping Yuanshi, Wang Mang ordered to build the Ziwu road and set up the Ziwu pass.

During the Qin and Han Dynasties, when transporting supplies from Sichuan and Hanzhong to the capitals of Xianyang or Chang’an, most of them took the Baoxie Road and the old road instead of the Meridian Road. Like the Tangluo Road, small groups of soldiers and horses were still possible, but they were not suitable for large groups of troops. .

The fifth road, the army goes all the way west from Chang'an, enters Jieting and Tianshui County in the Xiliang area, climbs the towering Qishan Mountains to the south, then walks east to Jianwei, Hechi, Baimashu... and finally enters the hinterland of Hanzhong!
This road is the most distant, and it takes a detour of thousands of miles, but the road is relatively easy to walk. The water is sweet and the soil is thick along the way, and the population is large. The army can collect food and grass along the way, reducing the pressure on logistics supplies!

In the past, this is what Zhuge Liang said when he came out of Qishan.

"Everyone, please take a good look. There are many mountain roads and canyons in Hanzhong, and they all rely on plank roads to communicate with each other. This is the model of plank roads..."

However, Feng Yi has a unique talent, and he has done a lot of homework. He has also studied the terrain, customs and customs of Bashu mountains and rivers thoroughly, and he speaks logically.

Moreover, the preparations are extremely well prepared, and people have made a plank road model based on the idea of ​​the sand table, explaining its design, construction, use... and various advantages and disadvantages in detail!

There are many mountains and valleys in the Hanzhong area, and there is no Yangguan Avenue to walk at all, so we had to spend countless manpower and use the method of "burning fire and stimulating water" to set up plank roads on the cliffs!
The method is: when a big stone blocks the road, first burn it with a strong fire, then pour cold water on it, and after the stone is soft, smash it with a giant hammer...

When encountering cliffs, holes are drilled on the cliffs, cross-bars are erected, planks are laid, and then connected together with pliers.

Every [-] to [-] miles, an open and watery place will be chosen to build a plank road pavilion, and a large number of houses and warehouses will be built for pedestrians to rest, stay, and avoid bad weather!
With such wisdom, the ancients opened up roads in the mountains and connected Guanzhong, Hanzhong, and Bashu into a whole. However, although the plank road is exquisite, it also has several major shortcomings:
First of all, the plank road is built along the cliffs, hanging high in the air, and the bottom is either a deep abyss or a rushing river. If you look at it with fear, you will tremble when you walk, and you will die if you fall!
Secondly, most of the plank roads are wooden structures, so the load-bearing capacity is limited, and only infantry, horses, and small carts can be used... and the team needs to be lengthened to reduce the pressure on the feet. It is difficult for four-horse heavy chariots and heavy siege equipment to pass. of!

It is precisely because of this that it is not easy to attack the land of Bashu, but it is also not easy to fight out of the land of Bashu.This logistical pressure is really frightening.

Finally, there is a lot of rain in Yizhou area, the wood is easy to rot, and there are often falling rocks in the mountains, so the plank road is easy to be damaged, and it is often repaired while walking, and how many lives are filled!

Therefore, people in the world say: "Walking the middle road of Shu is like approaching the gate of ghosts. Ten people go out, and nine of them will not return home. The bones of the dead hang in the mountain stream, and ghosts cry in the abyss. If you want to survive, you have to go far away!" '

It is precisely because of this that so many generations of writers have left behind the eternal words like "the road to Shu is difficult, and it is difficult to go to the blue sky".

"Hiss!" Hearing Feng Yi's description, many generals gasped.

Although I have heard of the dangers of the Shu land in the past, I don't have a real awareness.Today, after listening to Feng Yi's narration, I felt a little bit of a glimpse.

If the enemy army ambushes a group of troops in a dangerous place, condescending, and outflanking them, then they may never return!

Fortunately, Wang Jian and Wu Qi's soldiers and horses cooperated in Jingzhou's direction, and they attacked from multiple directions. If they only attacked from Yongliang and Liangyang, if they were not careful, maybe it would really be the case. A bloody end.
