"If the army wants to enter Hanzhong from Guanzhong, there are three ways to go from east to west:

The first Bao Xiean Ancient Road, from the south of the Baogu Mouth, north to the mouth of the Xiegu Valley, along the Bao and the Diagonal Two Rivers, runs through the entire Qinling Mountains, the total length is about 400 miles, avoiding a lot of dangerous peaks, it is a relatively easy to walk the valley road!

In the past, King Wen of Zhou passed through Bashu, that is, by the Baoxian ancient road to the south, after the Warring States - Qin Zhaoxiang King, and used a lot of manpower, material resources, on the cliff cliff of the road - the cave mountain for the hole, the wood for the beam, the valley road paved into a plank road, known as 'plank road thousands of miles, all-encompassing', firmly controlled the Bashu region!

The second ancient road, also known as 'Chencang Road', goes southwest out of Dasanguan from Guanzhong-Chencang, goes along the valley road in the upper reaches of the Jialing River, turns southeast into the Baogu Valley, and goes out of the valley mouth to the hinterland of Hanzhong.

In the past, Liu Bang was named the king of Han, unwilling to live in Bashu, but worshiped Han Xin as a general, Ming Xiu plank road, dark Chen Cang, the army entered Guanzhong from this road, eliminated the 'Three Qin Kings' in one fell swoop, and fought with Xiang Yu in the east for the world!

On the third road, the army went west from Chang'an, entered Jieting and Tianshui County in the Xiliang area, climbed the towering Qishan Mountains to the south, and then went east to Jianwei, Hechi, and Baimashu...... Finally enter the hinterland of Hanzhong!

This road is the most far, to detour thousands of miles, but the road is relatively easy to walk, along the way the water and soil are thick, the population is large, the army can requisition grain and grass along the way, reduce the pressure of logistics supply!

Everyone, please look at it, there are many mountain roads and canyons in Hanzhong, all relying on the plank road to communicate with the Quartet, this is the model of the plank road......"

Ma Liu has a unique talent, not only to control the operation of Guanzhong, but also to study the topography of the western mountains and rivers, customs and customs, and it is the first thing to say.

And it is very well prepared, and it is also necessary to bring up a model of the plank road to explain its design, construction, and use in detail...... And all sorts of pros and cons!

The mountains and valleys in Hanzhong are heavy, and there is no Yangguan Avenue to go at all, so I have to spend countless manpower to open a plank road on the cliff with the method of 'fire and water'!

The method is: when the road is blocked by a large stone, it is first burned with a fierce fire, and then poured cold water, and after its stone is soft, it is broken with a giant hammer......

In case of cliffs, then drill holes on the cliff wall, erect horizontal logs, lay wooden boards, and then connect them with pliers and nails......

Every twenty or thirty miles, we will also choose an open and watery place to build a plank road pavilion and build a large number of houses and warehouses for pedestrians to rest, stay and avoid bad weather!

With such wisdom, the ancients opened up roads in the mountains and mountains, connecting Guanzhong, Hanzhong, and Bashu into a whole, but although the plank road is exquisite, it also has several major shortcomings:

First of all, the plank road is built along the cliff, hanging high in the air, below is either an abyss, or a rushing river, look at the frightened, walk up and tremble, fall down will definitely die!

Secondly, most of the plank roads are wooden structures, so the load-bearing capacity is limited, and only infantry, horses, and carts can be walked...... And to lengthen the line to reduce the pressure on the feet, the horses and heavy chariots and heavy siege equipment are not passable!

Finally, there is a lot of rain in Yizhou area, the wood is easy to rot, and there are often rockfalls in the mountains, so the plank road is easy to destroy.

Therefore, the people of the world say: 'Walking in the middle of the Shu Road, such as the ghost gate, ten people go out, nine do not return to their hometown, the mountain stream hangs white bones, the abyss hears ghosts crying, if you want to survive, retreat and go far away!' ’

"The last general has been fighting for more than 20 years, and he has walked seven or eight points in the world, and he has never seen such a dangerous place, let alone attacking the city and plundering the land, I am afraid it will be difficult to walk over!"

"The cliffs are steep, the mountains and rivers are treacherous, this is the Jedi of soldiers, who will go to such a place unless it is absolutely necessary?"

"If the enemy army is in a dangerous place, ambushes a group of men and horses, condescending, and outflanks us in front and back, I am afraid that we will have no return!"

…………

Most of the people who attended the meeting today were battle-hardened generals, thirsty for blood from their swords, trapped in the saddle, crawling and rolling in the pile of dead, and fighting without retreat!

But after seeing the terrain of Hanzhong and the three roads, all of them are not in good spirits, and it is difficult to walk in this kind of ghost place, so how to arrange troops, attack and kill, and defend?

Not to mention the generals, even after Xiao Yi saw the terrain, he had a strong impulse, not in a hurry to fight to the death with the enemy, but to die down, return to the court, and live a small life with his wife...... Why suffer this sin?

Xiao Yi calculated in his heart that as long as the Hanzhong guards are not the product of stupid, foolish, or inbred marriage, then no matter which road he takes, the chance of winning will not exceed thirty percent, and the end of failure is - there is no way back and the whole army will be destroyed!

No wonder in history, when Cao Cao attacked Hanzhong, he sighed and said to his subordinates: 'Hundreds of miles of dead mountains and valleys, this is not a useful place, if I had known such terrain, I would never have brought troops here!' ’

It is no wonder that in the original history, with Zhuge Kongming's outstanding talents, he returned from Qishan in vain, and was blocked by Sima Xiaoer's hands, not because of lack of ability, but because of the terrain!

The Qinling Mountains are steep, the plank road is rugged and difficult to travel, and more importantly, in the process of marching, the army has to resist the enemy's ambush, but also to attack the city and seize the land, and the difficulty is increased several times!

Zhang Ling, Zhang Heng, and Zhang Luzu and grandsons have been entrenched in Hanzhong for decades, spreading doctrines, recruiting believers, and establishing a **** local government, and they are quite popular!

Especially since Dong Zhuo's rebellion, the people of Guanzhong have suffered from it, and they have moved their families to the south, and settled in the relatively stable Bashu and Hanzhong, and now the population of Hanzhong County has exceeded 500,000 people, which is comparable to the land of a state in the Central Plains!

Therefore, although Zhang Lu's territory is small, it is small and powerful, the ordnance, money and food are very sufficient, there are 100,000 soldiers, all of whom are followers of the Wudoumi Sect, under the influence of its teachings, they are loyal to their superiors, and they are not afraid of death in battle, but they are a hard bone to gnaw!

Then again, what is a hero, who can do what others can't, dare what others don't dare, know that there are tigers in the mountains, and prefer to go to the tiger mountain......

"There is no turning back from the bow, more than 200,000 horses gathered in Guanzhong, and countless money, grain and grass have been spent, how can we return in vain, even if Hanzhong is a copper wall, this big Sima will also crash out of a hole!

During the Warring States Period, the Qin general-Sima Coo's division went south, took the Hanzhong plank road to attack Bashu, and turned it into the backyard of Qin, indicating that you can use force from north to south!

During the Chu and Han dynasties, Han Xinming repaired the plank road, secretly Chen Cang, and took the land of Guanzhong in one fell swoop, laying the foundation of the Han Empire, showing that soldiers can also be used from the south to the north!

What the ancients can do, we can also do, and we must do it even better, conquer Hanzhong, conquer Bashu, and include the southwest in the territory, you and I can go down in history! ”

The army is fighting, morale first, Xiao Yi slammed the handsome case, like a storyteller, and talked about the classic battle examples of ancient times, not only to cheer up his subordinates, but also to cheer for himself!

China has been up and down for 5,000 years, and there are countless heroes, and there are countless famous generals, and Xiao Yi admires two of them the most: one is the killing god Bai Qi, and the other is the soldier Han Xin!

It's a pity that I crossed the wrong time, and I couldn't fight against these two on the battlefield and fight against each other, which is really a big regret in life, but there is also a remedy, which is to lay a more classic battle and create a more powerful feat!

The battle of the Han army in the north of Hanzhong was the first battle after Han Xin took the stage to worship the generals, and it was also the battle of fame...... Ten great achievements!

If he is in the land of Hanzhong, and he also fights a beautiful battle, won't he prove to the people of the world that his skills are not under Han Xin, or even higher?

Thinking of this, Xiao Yi suddenly felt energetic, as if he was several years younger, if he could defeat the soldier immortal, he would be the new soldier immortal!

"Man, husband, it is a great fortune in life to be able to die on the battlefield and the horse leather shroud, so why should we be afraid?"

"There are only generals who die in battle, there are no cowards who retreat, and the last general is willing to die for Da Sima!"

"The last general is willing to be the vanguard officer, the first to enter Hanzhong!"

Under the encouragement of Xiao Yi, the generals also had morale, and they all wanted to serve as vanguard officers, and they were the first to enter Hanzhong, enter Nanzhengcheng, and capture Zhang Lu!

It is very good to have high morale, but it is not okay to send troops recklessly, Xiao Yi waved his hand lightly, signaled everyone to calm down, and continued to discuss the matter of attacking Hanzhong, the Qinling Mountains stretch for thousands of miles from east to west, are there only those three roads to go?

"Ma Liu, the army is attacking Hanzhong County, are there any other roads?"

"Yes, you can say no, it's a dead end!"

"Dead end, make it clear!"

"Meridian Valley!"
