Sanguan is located between the steep canyons, and in front of it is the well-known Chencang Shu Road.

"Wei Changshi, the south of Sanguan is the mighty city of the Shu army?" Wei Yuan looked very knowledgeable, and Chen Xu then asked.

"Yes." Wei Yuan naturally had to answer all questions, nodded and said, "The mighty city is located in Chencang Road, and the Shu army has also stationed men and horses in Tangcang Town on the west side of Shu Road. ”

Wei Yuan is worthy of being the chief of the shogunate, and he answers Chen Xu's questions fluently.

Weishui originates in Longxi, passes through Qinzhou, passes through Chencang, and is located in the north of Sanguan and Chencang.

The Gudao River connects the Jialing River, and the direction of the river is roughly similar to that of Chencang Road. From Chencang, Fengzhou, Xingzhou north-south direction.

The Sanguan where Chen Xu and the others are located is to the west of Chen Cang, about thirty or forty miles away.

If the Wei army wants to take Fengzhou, it is necessary to pass through the Chencang Road, but this road is not easy to walk, the Wei army wants to fight the Shu State, people must be unwilling, there is a mighty city blocked in the Shu Road, and the defenders of Tangcang Town on the west side of the Shu Road echo each other.

In addition, in the middle of Chengzhou and Fengzhou, further south is the solid town garrisoned by the Xiongsheng army of Shu State.

Qinzhou is located in Longyou, condescending, rushing down is Guanzhong.

Chen Xu hurriedly took out the pen and paper he had brought with him, and recorded and drew the geographical location of these relatively large cities, transportation arteries, and military gates.

First, he drew the coordinates of the scattered pass he was in the center of the white paper.

Then draw a short line with a ruler in the lower right corner of the paper, and mark 10 miles on the short line.

With Sanguan as the center, the larger towns such as Qinzhou, Fengzhou, Chengzhou, Jiezhou, Guzhen, Xingzhou, and Shannan West Road Jiedu Xingyuanfu were drawn one by one, and according to the approximate distance that Wei Yuan said, according to the short line representing 10 miles just made as the target, the distance between the upper city and the city was marked in equal proportions......

In this way, the geographical location of each city is clear at a glance, and then, he marked the location of some walled cities (Tangcang Town, Weiwu City) of the Shu army in Chencang Road, attached rivers and waterways, and traffic roads......

A simple map was born.

Wei Yuan and Yuan Jizhong on the side looked at Chen Xu with interest and relish, and depicted this military picture with a serious face.

Ancient military maps are not as professional surveying and mapping technology as modern ones with scale, contour lines, etc., and are still relatively primitive.

When visiting Wang Jing, Chen Xu had borrowed the topographic map of the mountains and rivers on the Fengxiang Mansion Jiedu Envoy, the words are very large, there are mountains and rivers but the ancients did not have the concept of scale, the water system on the march map is high mountains, the city is important, the big place is not too big, the small place is the boss of the painting, quite the style of abstract painting...... sweat

So Chen Xu had the idea of making his own drawing.

He didn't graduate with a major in cartography and mapping, but at least he knew the scale, and in this era, which was probably in the period of the Five Dynasties of China, he was standing on the shoulders of giants, and you must know that the concept of scale in Chinese maps in the previous life germinated in the Song Dynasty.

After the military map was completed, Chen Xuyou checked it again and confirmed with Wei Yuan whether it was correct, but he was still a little dissatisfied with the class.

The place where Sichuan and Shaanxi are at the throat of traffic is a place where soldiers must fight, but because neither Wei and Shu are at war, the Shu side stays honestly in their own territory, and basically does not invade and provoke trouble in peacetime. Therefore, the dispersal at this time seems to be extraordinarily calm.

It's just that now the scope of this military map is too large, and what he needs is a more accurate local map, especially the military deployment of the Chencang Daoshu army and the distribution of military passes.

So, he decided to stay in Sanguan for the time being.

By the way, I had a good relationship with the guards of Sanguan and asked them about some of the deployments of the Shu army.

Although the Shu army basically did not take the initiative to attack, the soldiers stationed in Sanguan would regularly send scouts to check the enemy's movements, and sometimes capture a few local people.

Unfortunately, the locals found by the scouts had already been released, and the Wei army only brought them over for interrogation, and did not hurt their lives.

The guards still attached great importance to them from Tokyo, and the next day, they found a few guides.

Chen Xu was looking at the map, and at this time, He Meng led an old man who looked older into the house.

This old man surnamed Liu, with white hair and a face exposed to the wind and sun, thin and black, may be due to the fear of the identity of the martial artist, and his expression seems a little restrained.

Chen Xu tried his best to use a friendly expression and asked, "Old man, are you a person who lives nearby, and what are you doing?"

The old man replied tremblingly: "General, the old man's family lives in a village in the Qinling Mountains, and he usually makes a living by selling goods."

Chen Xu was overjoyed when he heard this, the peddler has been traveling all the year round, and he must know the terrain and roads very well, otherwise he will definitely get lost in the rugged roads in the Qinling Mountains.

The old man was illiterate, so Chen Xu asked them one by one, especially the information on Chen Cangdao.

"Old man, how many roads are there from Fengzhou to Guanzhong?" Chen Xu asked.

The old man replied in 1510: "Don't hide it from the general, if you want to get from Fengzhou to Guanzhong, there are two roads, one is to take the Shu Road along the Jialing River, that is, Chencang Road, and the other is to go from Tangcang Town in the Qinling Mountains on the west side of the Shu Road."

"Tangcang Town can go to Qinzhou to the left, and there are two roads to the right to the Huanghua Valley in the Shu Road, and along the Shu Road by the Jialing River from Chencang to Guanzhong."

While listening, Chen Xu sketched on the drawings and drew a local road map about Shu Road.

No wonder Li Baishi said: "Shu Road is difficult, it is difficult to go to the sky!" It's twisted and turned, and it's confusing just to look at.

"Old man, I'll send a few people to follow you and go back with you to do business, and if anyone asks, say it's a partnership. Do you think it's okay? An idea popped up in Chen Xu's mind, and then he asked kindly.

"I'll give you a consistent amount of money in January, and the people who sell goods with you will give you in monthly installments, how about it?"

Qin Feng and other states still belonged to the Central Plains more than ten years ago, but later they were occupied by Shu due to turmoil, and they were fighting civil wars, not foreign invasions, and they had money to take, and the locals were willing to be guides.

So, it was very happy and smooth to reach an agreement.

After staying for a few more days, the one that should be deployed had been deployed, and Chen Xu and the others embarked on the way home.

On the way, I passed through Huazhou, and one of the world-famous five mountains, Xiyue Huashan, was under the rule of Huazhou.

In his previous life, Chen Xu only heard his name, but he did not reach his realm, and when everything on this trip was over, he wanted to stay for a few days and have a glimpse of Huashan, which is unique in the world.

The long sky plank road, the harrier turns over, and the thousand-foot building......

Swim to the Lotus Peak, the main peak of Huashan Mountain, a heavy rain is coming, and the group rests in a Taoist temple on the west peak.
