Shu County, Tiandang Mountain.

Braving the bitter cold winds and the fine snow, tens of thousands of Qin prisoners of war, as well as the Shu people, were forced to wield hoes and carry wood to build passable plank roads for the Wu army.

With a "snap", a whip was whipped, and the Qin prisoners of war, who were already too tired, couldn't help but wail, their bodies were already peeling and fleshy, and their hands were full of frostbite, but they were still driven to work harder......

"Quick!"

"Don't be lazy!"

"Those who are slacking off will have their porridge halved!"

Sergeant Wu, who was in charge of overseeing the work, roared viciously, forcing the laborers to work hard.

It's just that Shu Road is difficult, and it is difficult to go to the sky.

"Ahh

One was working hard, and the other was careless, and after stepping on the air, he fell off the cliff and was buried in the clouds, and disappeared, only the long-lasting cry still echoed in the valley......

"Gollum."

Seeing that another unlucky laborer fell to his death, whether it was the rest of the laborers or the Wu soldier in charge of supervising the work, they couldn't help but swallow a mouthful of saliva, some of their scalps were numb, and they were terrified.

After all, the terrain of this Shu land is too precipitous, too terrifying.

Not to mention the cliffs and cliffs that are difficult to walk everywhere, they are still in the clouds and fog, and the view is a lake, so there are often laborers, and even the overseers are thrown to death.

At this time, not far from Tiandang Mountain, on a mountain peak, Sun Wu, Gongzixi and Bu Shang looked around, looking at the terrain here, and couldn't help but look at each other.

"Bring me the map."

Sun Wu took a sheepskin map from the hands of his own soldiers, and then sat on the ground and spread out the map, studying it carefully.

】

"Bu Junshou, do you have a detailed map?"

Sun Wu asked.

Bu Shang nodded and said, "Absolutely detailed." This map of mine was drawn according to the king's requirements, and every stroke was sent to investigate on the spot. ”

"Good."

Sun Wu nodded, pointed to the location of "Nanshan" (Qinling), and said: "Gongzi, Bu Junshou, you see, this is Nanshan, and now the place where we are located, north of Nanshan, south of Hanshui and Bashan, is the western gateway of Hanzhong, and it is also the northern frontier of Bashu to Qindi, and the geographical location is very dangerous. ”

"Its right side is barberry, the sky swings, the left arch is full of clouds and mist, Han, black, and all the water belts are wrapped in it, which can be described as the most dangerous in the world."

"If you build a fortress from here, you can attack it and defend it, but you don't have to do it now."

"I have estimated that if 10,000 elite soldiers set off from Tiandang Mountain, pass through the plank road, and cross Nanshan, they will be able to reach Yongcheng, the capital of Qin, in fifteen days at most."

10,000 elite soldiers crossed Nanshan and attacked Yongcheng?

Sun Wu really dared to think about it!

Bu Shang couldn't help but laugh and said: "Guowei, the terrain of Nanshan is high and the valleys are deep, and the weather is unpredictable. ”

"Even if our army builds a plank road and sends troops from the road of praise and obliqueness, the Qin people will definitely deal with it, and there are only 10,000 elite soldiers, but I am afraid that before the troops come to the city of Yongdu, they will already be blocked by the Qin army."

Hearing this, Sun Wu said with a smile: "Bu Junshou, I didn't say that I would send troops from the road of praise and obliqueness. ”

"This ...... Where did the lieutenant send his troops from? ”

Bu Shang was quite puzzled and said: "As far as I know, there are only two passages in Nanshan, one is Wuguan Road, and the other is the road of praise and obliqueness, why is there another way?" ”

If you enter Qin from the land of Bashu, the only road that can be passed is the road of praise and obliqueness.

As for the Wuguan Road, it was from Hanzhong County in Wu to Qin, and it was also a necessary route on the Silk Road.

This way of praise has been opened up as early as the time of Dayu.

In the past, King Wen of Zhou and King You of Zhou cut down Shu, which marched from the road of Bao Xie, and the entrance of Bao Xie Road was in the south of Zhou Yuan.

The slope is actually a valley and two mouths, although it crosses the Qinling Mountains, it does not have to climb over the mountains.

As far as its general trend is concerned, the Baochuan Road is the valley road with a relatively flat and fast route among the Qinling Mountains.

However, the southern section of the Baogu valley through which it passes is deep and rapid, and the cliff is volleying.

The slope is only a valley road, and its desperate place must be climbed, which is difficult and hard work, and it is unspeakable.

The reason why Sun Wu built the plank road was actually instructed by Qingji.

His task was to make holes in the caves and mountains between the cliffs and cliffs passing through the road, insert wood into beams, lay wooden planks and connect them into pavilions, and connect them to the road.

Because of the heavy grain and straw of the Wu army, it is difficult to pass through the valley road, so the "plank road" had to come into being!

"The way of praise and slope is to build a plank road. I intend to reopen a plank road, which leads directly to Qindi, and catch the Qin people off guard. ”

Sun Wu's finger pointed at a place called "Yu County" in the Qin State.

On the side of the Bao Slope Road, there is a section of the Jialing Ancient Road, which is turned southwest along the water valley of the old road, and can reach the Yu County of the Qin State. The Qin people must not have thought that our army could be killed from Yu County. ”

“……”

Bu Shang fell into deep thought.

If Qingji is here, you must recognize that "Yu County" is the historical Chencang, and the new plank road that Sun Wu wants to open up is actually "Chencang Road"!

In the eleventh year of Qin Wugong, that is, in 687 BC, Qin destroyed Xiyu, so Yu County was established.

This is the origin of Yu County.

At this time, Gongzixi frowned and said, "Captain, is this too risky?" ”

"If 10,000 elite soldiers cross Nanshan, they can really reach Yuxian, but if they want to break through Yongcheng, they can't do it anyway."

"Instead of spending time and effort to build a plank road from scratch, it is better to attack Qindi directly from the road of praise or the road of Wuguan."

Hearing this, Sun Wu just shook his head and said, "Childe, the reason why elite soldiers are elite soldiers is mainly because of surprise wins, not fierce attacks. ”

"Attacking Qin from the road of praise and obliqueness, the Qin people can be a master, and they can't do it."

"I personally led the army from Wuguan Road to attack Qin, after the successful construction of Xindao, 10,000 elite soldiers can quickly attack, capture Yu County, and then gain a firm foothold, forcing the Qin people to divide their troops and fight, or they can take advantage of the weakness to enter and break the Qin capital."

"Good."

Gongzixi finally knew about Sun Wu's plan.

Sun Wu set his eyes on Bu Shang's body again, and said slowly: "Bu Junshou, to build this new road, it takes a lot of manpower. ”

"Now that there is a shortage of manpower, I wonder if you can suspend the Dujiangyan project and use more than 30,000 Persian prisoners of war to build a new road, and at the same time recruit more people?"

Hearing this, Bu Shang bowed his head slightly and said: "I have no objection to the national captain to use Persian prisoners of war. ”

"It's just that tens of thousands of people have been recruited by the Shu people, and the land of Shu is newly attached, so I have to worry about the chaos of the Shu people and the disaster of the front-line army......"

Sun Wu thought for a while, and could only sigh: "Then, we can only make the Kunlun slaves who originally escorted the grain and straw heavy to the labor of building the new road." ”

In order to complete this new road, which was hundreds of miles long, as soon as possible, Sun Wu had to retreat to the next best.
