"Uncle Tang, since this place is a cave mountain, why do the plank roads of the Ming Dynasty still have to be built here, they are not afraid of what is in these cave mountains?"

Song Siyuan observed the map, and it was easy to see that the Yungu plank road crossed the cave mountain area, which also means that the Yungu can see the Wanyan cave mountain throughout the whole process, such a strange and strange place, the ancients were so superstitious, how could they choose such an unlucky place to build hundreds of miles of plank road.

Old Man Tang thought that he knew the reason, coughed lightly, and explained to them the reason why the Yungu Plank Road was built here.

Since ancient times, thousands of miles of Qinling Mountains have stretched and precipitated, and the Baochuan Road and Chencang Road are the most special!

Let's talk about Chen Cangdao first.

At the end of the Qin Dynasty, Liu Bang and Xiang Yu fought for the world, Xiang Yu personally set up a Hongmen banquet to take Liu Bang's dog life, he saw Xiang Yu's meaning, and left the Hongmen banquet under the pretext of urinating, and fled back to the Hanzhong fiefdom from the Qinling plank road.

Although Liu Bang said to the outside world that he would never leave Hanzhong, he has been cultivating the plank road in the open and Chen Cang in the dark, so paralyzing Guanzhong, this is the opportunity to attack the west by going out of the old way, and pacify the three Qins in one fell swoop.

Chencang Road has since been known as the Qinling Ancient Road!

As for the Bao Slope Road, it has a lot to do with the pre-Qin period.

It is rumored that the Bao Shute Road is the product of the Three Emperors and Five Emperors era, the plank road built for the Xia Yu period, to the pre-Qin Huiwen King period, Fan Ju will enter the phase, in order to develop the economic and trade exchanges between Qin and Bashu, so that everyone in the world knows the power of Qin, decided to rebuild the Bao Chute Road, widen the original narrow plank road to three meters, and set up a post war for the merchants to rest.

Since then, the Shu Han merchant department store has been continuously transported to Guanzhong, and it has also become the main road of economic and trade exchanges between the north and the south, and the march to the Tunguan, which is called "a thousand miles of plank road, all-encompassing", and the golden bull that destroyed the Bashu country, it is from here that the sword pavilion road in Hanzhong enters Sichuan and Shu!

The allusions of the ancient road of the Qin and Han dynasties can't be finished, so let's not mention it for the time being, let's go back to Wanyan Cave Mountain.

Wanyan Cave Mountain is located west of the Qinling Mountains, distributed at the southern foot of the mountain between Chencang Road and Bao Slope Road, which has been famous for mysterious cave mountains thousands of years ago.

Their records, the earliest can be traced back to the period of the Three Emperors and Five Emperors, the legend Xia Yu chiseled the slope, is to open the mountain in the Qinling Mountains to take stones to smelt Jiuding, these caves are the caves left when the raw materials of the Jiuding were chiseled, some people say that the Qin and Han dynasties died tens of thousands of soldiers when they repaired the Sword Pavilion Road, and their souls became tens of thousands of cave spirits in the long sleep cave, and even more, it is rumored that this is the heart of the Qinling Mountains, which inhabits the old gods of the Qinling Mountains, which is the first taboo place in the world.

So heavy, there are different opinions, no one knows how long this cave has existed, and I don't know what to do, and because of the treacherous terrain of the mountain, wild beasts and birds mostly build nests and nests in the caves, entrenched, once the living people enter the vicinity of the cave mountain, the most heard sound is the strange beast roaring birdsong, if the beast roars in the cave, then it adds a trace of terror.

In this case, the cave mountain is actually more like the ghost domain cave in the eyes of ordinary people, not many people are willing to take the initiative to come, but also because there are few people in the city, once people arrive near the cave mountain, they often get lost and are attacked by wild beasts and birds of prey, so that they never get out of the cave mountain.

To this day, no one has ever been able to walk through the entire cave unharmed.

It can be said that the cave mountain has not become mysterious because of the ancestral soul palace at all, but the soul palace is built in the depths of the cave mountain, which guarantees that it will never be discovered by outsiders, and it can still exist with the ancestral vein of Qinling Mountains until today, even if you can't hear the legend of the soul palace, whoever sees these caves will only feel that they are ghost caves and spirit nests.

In this case, the cave is actually more terrifying than the Soul Palace, after all, the Soul Palace is only a palace built by the Tang Dynasty, with a name and a surname, and the people are only curious and afraid of the Soul Palace rather than frightened.

After the Ming and Qing dynasties, Chencang Road, Bao Chuan Road is still used as an important passage for goods to enter and exit the south, after the development of north-south trade, the robbers with the mountains see that it is profitable, and gradually entanglement of grass people fleeing households to gather into a village, to rob merchants along the road for a living.

Even if the merchant escorted a cart of rice bran, he had to catch a handful and feed the livestock, in this case, even if the merchant really wanted to do business trafficking, but also because of the mountain bandits' chaos stopped, these mountain bandits knew that the Qinling Mountains were mountainous, so they took the Wanyan Cave Mountain between the two roads as a stronghold, occupied the mountain in the cave and set up a village, waved the flag and shouted, the imperial court sent troops to suppress the bandits many times, all failed because of the caves and caves, and the government never knew which cave these bandits were hiding, not to mention a lot of manpower and material resources, not to mention that even a mountain bandit was not caught.

Later, Liu Bowen looked at the mountain and observed the qi, found that the evil spirit of the cave mountain was strong, and the righteousness did not exist, thinking that the evil spirit was strong here to gather thieves, in order to completely solve the scourge of bandits in Qinling Mountain, he proposed to the Taizu of the Zhu Dynasty to rebuild the Yungu plank road, protect the freight of the pass, and also use the plank road as a sword to cross the cave mountain, in order to suppress the evil in the cave mountain.

After him, the Zhu Dynasty government rebuilt the Yungu plank road in the Hongwu period, connected the Phoenix Post and the Wusheng Post with 2,275 post pavilions, and monitored the entire cave mountain area with a 400-mile plank road.

If the Phoenix Post is compared to the hilt of a sword, the Martial Saint Post happens to be the tail of the sword, like a sword piercing the cave mountain, so that it will be suppressed by the sword forever, and there is no possibility of doing evil.
