When Wang Rong came to Chencang City with the Wu Wei Army, the fifth candidate was already waiting here.

Wang Wei looked at the fifth candidate who saluted respectfully at the east gate of Chencang, did not speak, shook the reins of the horse, and drove the horse into the city.

Wang Xu rode his horse to the front of the fifth candidate, saluted on his horse, and said, "Fifth commander, you hurry up and get on your horse and follow you to the county office."

The fifth candidate replied gratefully, "Thank you to General Wang, and I will ask General Wang Baijiang to take care of me in the future."

For Wang Xu, the fifth candidate did not dare to slack off. Wang Mao, the commander of the previous Wang Rong's guards, was already the commander of the Armed Guards. It can be said that Wang Xu has a bright future in the future, and of course the fifth candidate must befriend the other party.

Wang Rong came to the Yazheng Hall of Chencang County to sit down, and Wang Xu took a group of Xiaojie guards to stand on both sides of Wang Rong.

Wang Mao, Zhang Yunshu, Ouyang Xun, Wu Luo, Li Sujie, Chu Luxu, Meng Sheng, Yuan Tiangang, Bai Su, Chang Wo and Liu Linshan and other generals of the Armed Guards sat down on the left side of the hall.

The Third, Fourteenth, and Nineteenth Armies, led by their respective commanders and commanders, sat down on the right side of the hall.

Wang Rong looked at the many generals in the hall and took the lead in saying, "Fifth, what information has your Detective Department detected at this time?"

As soon as the fifth candidate heard Wang Rong's inquiry, he suddenly came to his senses, he came out of the ranks, bowed to Wang Rong and saluted: "Your Majesty, after Li Song captured Hanzhong County, he led the Bashu army to block the old road, the Baochuan Road, the Fu Luo Road and the Meridian Road."

Wang Rong asked with a surprised face, "Li Song has so many soldiers and horses? Can they be stationed on the main roads in Hanzhong?"

The fifth candidate nodded and said, "Since Hanzhong County was captured by Li Song, he forcibly recruited men between the ages of fifteen and sixty into the army, and the army swelled to 200,000 people. Moreover, according to the news that the detectives led by the priest Cen Yu came back from the investigation, the road of Fu Luo was extremely difficult and dangerous, and there were many poisonous insects and beasts. The army can't march at all, so the Bashu army in Fu Luodao is the least, only more than 2,000 people."

The fifth candidate handed over a detailed piece of information with both hands, and the paper detailed the situation of the four main roads from Guanzhong to Hanzhong.

Fu Luo Road is a post road that crosses the Qinling Mountains from Chang'an to Hanzhong and Bashu. Because from the south of Chang'an to take this road must first pass through the Xiluo Valley of Xuwu County, follow this road over the Qinling Mountains and then exit to the south for the Hanjiang River tributary Fushui River Valley, so it is called Fu Luo Road.

Although Fu Luo Road is named after Fu Valley and Luo Valley, but the two valleys are not directly connected, the middle has to pass through the river valleys such as West Luo Valley Water, Hei Shui, Huangshui, Youshui, Fu Shui, etc., and cross the Eighteen Pan Ridge between West Luogu Water and Heishui, the main ridge of Qinling between Heishui and Huangshui, Xinglongling between Huangshui and Youshui, Niuling and Guanling Liang between Youshui and Fushui, and the West Luoshui River Valley is only 40 miles and the Fushui River Valley is only 100 miles The section of the road section only accounts for one-seventh of the whole journey. Therefore, Fu Luo Road is a winding valley road composed of many valley roads.

Fu Luo Road from Chang'an to the southwest, to Xukuo County, turn southwest 30 miles from the West Luo Valley into the Qinling Mountains, over the Luogu Pass, over the Laojun Mountains, trace the west source of the black water over the Qinling Mountains, into the Han River tributary Huangshui source, and then to the southwest over the Xinglong Mountains to the upper reaches of the Youshui, to the southeast along the Youshui out of the mouth of the Fugu; or to the southwest, Yueniuling follows the Bali River, a tributary of Youshui, to Baliguan; or from the Bali River valley over the ridge out of the Fu Valley; You can also follow the Fushui River valley from Niuling to the southwest, cross the water along the north bank of the Han River, and arrive at Hanzhong through Chenggu County. The total length of the route is about 770 miles, of which the valley road is about 500 miles, which is faster than other post roads leading to Chang'an, such as the old road, the Baochuan road, and the meridian road.

Although the Fu Luo Road has the advantage of being short, the height of several mountains climbed on the way far exceeds that of other roads, and the road is extremely difficult. The mountains near Luoguguan are steep, and the roads wind between the tributaries of the Qinling Mountains and the black water, rising and falling in the sparsely populated primeval forests infested with wild beasts. Even after crossing the Qinling Mountains, the road into Hanzhong is still "absolutely lingering, and the danger is endless", and there is also a dangerous place called "Yellow Spring", where there are many poisonous insects and beasts, and pedestrians regard it as a fearful road. Therefore, Fu Luo Road was opened and used late, and the time for being used as an official post road was also relatively short.

The most commonly used road from Guanzhong to Han is the old road, because the east branch of the upper source of the Jialing water - the source of the old road water source out of the south of the pass, so the source of the water is nearby, the Qin Dynasty set up the old road county. This road passes through Gudao County and runs along the Gudao water, hence the name Gudao.

Therefore, the road is also called Sanguan Road, which is named after Sanguan. Sanguan is one of the four stops in Guanzhong. It is recorded in the estimate: "Sekiyama Mountain River

The meeting will choke the intersection of the north and the south. The north must not be like this, and there is no way to enlighten Liang Liang; If you can't do this, you can't try to close the middle."

Sanguan was originally the pass of the Zhou Dynasty, so it was called Sanguan. Sanguan is located on the large Sanling in the southwest of Chencang on the north side of the Qinling Mountains, and the Sanguan controls the Sanguan Road.

The Sanguan Road that reaches Hanzhong and Bashu through Sanguan, like the Bao Slope, is also the traffic artery opened up in the early days of ancient Qin and Shu.

Therefore, the road is also known as "Chen Cang Road". It is because the north end of the road enters and exits the mountain pass for Chencang County. In addition, Chencang Road and the old road are connected as a route in Sanguan, so it is also called "Chencang Old Road".

Therefore, the road was the first road with many pavilions, and there were more than 3,000 pavilions. After the establishment of the Yong Dynasty, great importance was attached to the old way. With the progress of craftsmanship, the craftsmen gradually mastered the skill of "returning to the mountain to take the way" to build the road, and then replaced the pavilion with the road.

The road is also known as the side road. It is a section of the road that is built by excavating mountain rocks on one side of the cliff and facing the ditch on the other side in the turbulent water flow or the steep section of the cliff bank. It follows the slope of the mountain, with the elevation of the terrain, bending and surrounding, generally dozens of meters higher than the plank road, and is located in the middle of the mountain or the top of the mountain.

The road is made of earth and stone as the roadbed, which is firmer than the plank road, and the bearing capacity is larger, it is far away from the riverbed, and it is not easy to be washed away by floods in summer and autumn. Some sections of the road are limited to the terrain, and when the stack cannot be passed without chiseling holes, the wooden beams are changed to stone beams, and the trestle bridge is built to be firm and durable.

Its shortcomings: the route is winding, not as smooth as the plank road; Up and down the slope, it is not as straight as the plank road, and the difficulty of driving increases; In the rainy season, the road is muddy and difficult to walk, but the plank road is not muddy.

After such a renovation, the road was finally united and became a thoroughfare. Therefore, this road became the focus of Li Song's defense, and tens of thousands of people were stationed in Hechi, Fuxian and Yangpingguan. Yangping Pass is the top priority, and Li Song personally sits in charge.

Another key road leading from Guanzhong to Hanzhong, the Baochuan Road, was led by Xue Ting, who was sent by Li Song, to lead 50,000 troops to garrison Sanjiao as a barrier to Nanzheng City.

The slope was opened in the prehistoric period, and according to legend, it began to pass in the period of the Three Emperors and Five Emperors. In the ancient books, it is said: "The way of praise and oblivion, Xia Yu sent it". In the Zhou Dynasty, there was a record of King Wen of Zhou "cutting Shu", and later King You of Zhou conquered the country to get the beauty of Bao.

Although the ancient books do not clearly record the specific route of the Zhou Dynasty's "cutting Shu", the entrance of the Bao Slope Road is south of Zhou Yuan, so the Zhou Dynasty should have marched to southern Shaanxi through the Bao Slope Road.

During the Spring and Autumn Period, "Qin Wen, (Xiao) [De], Miao Juyong, the goods of Gap Long, and Shu were Duojia" ("Historical Records, Goods and Colonies"), and there were many trade exchanges between Qin and Shu through the Bao Slope Road.

In the period of King Zhaoxiang of Qin, the valley road of the Baochuan Road was chiseled into a plank road, so that "the plank road is thousands of miles, leading to Shu Han, so that the world is afraid of Qin", and it became the traffic artery between Qin and Shu during the Warring States Period.

Bao Shute Road is a road that follows the two river valleys of Weishui tributary Diagonal Water and Hanshui Tributary Baoshui, and crosses the Qinling Mountains from Chang'an to Hanzhong and Bashu. Because its north entrance is at the mouth of the Xiegu Valley in Yixian County, and the south exit is in the Baogu Valley in Hanzhong, it is called the Baochuan Road. From Chang'an to Hanzhong, first enter the valley, and then enter the valley, so it is also called the valley road.

The oblique water originates on the west side of Taibai Mountain, flows north through the east side of Wulipo in Taibai County, and then turns northeast out of the mouth of the inclined valley and injects Weishui. Baoshui originates from the southern foot of the Qinling Mountains, and has many sources in Taibai County, and the easternmost source is located in the area of Xigou and Tangkou Street on the west side of Wulipo.

The five-mile slope adjacent to the slope and the two rivers is a gentle slope about five or six miles long, and after this gentle slope, the inclined valley and the Baogu valley are communicated. Therefore, 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, the water is deep and rapid, the cliff is volleying, "even the height is deep", "the yin and the poor valley, ten thousand miles straight down, the reckless cliff cuts the wall, and there is no soil for thousands of miles...... The elk is incomprehensible, the apes look at each other, and the hooves and feet can not be crossed."

The ramp road is only a valley road before the plank road is repaired, and its desperate place must be climbed and walked, which is difficult and hard work, and it is unspeakable. To the Warring States Period, King Qin Zhaoxiang made Fan Ju as the phase, in the cliff between the cliffs and cliffs passing through the cave mountain for the hole, insert the wood for the beam, pave the wooden board for the trestle pavilion, connect the passage road, and then the slope road became the post road.

During the Qin-Yong period, the Baochuan Road was the main post road leading to Hanzhong and Bashu in Xianyang or Xuxi. Its route is roughly as follows: from Chang'an through Xu, Yixian, southwest from the mouth of the valley into the mountain, along the east side of the slope of the water south, passing

Diagonal water, turn over Baliban, enter the upper valley of the inclined water, and then go west to Wuliling to enter the source of Baoshui, then turn to the southwest, pass through the river pond pass to the upper reaches of the Baohe River Sanjiaocheng, and then pass through the stone gate or cross the Qipanling out of the Baogu valley, and then reach Nanzheng through Baozhong.

According to the route, it can be seen that although the Baochuan Road is closer than the old road, it is relatively difficult to walk, and there are Sanjiaocheng in the middle of the route, and the 50,000 Bashu troops are enough to make any Tang army general desperate.
