This is the original intention of Qin Gong Yingfei to find Jiang Wan and the others, he knows in his heart that this matter is very old and must be found from the file.

At this moment, Qin Gong Yingfei definitely didn't expect that Prime Minister Jiang Wan gave him a surprise in this matter.

……

The Chi Road of this era is almost equivalent to the national road of later generations, and the straight road is a military road, and the classification is extremely strict.

……

Before the Sui Dynasty, there was no Beijing-Hangzhou Grand Canal connecting the north and south, only the galloping road that began in the Qin Dynasty ran through the world, firmly controlling the Central Plains together.

Qin Gong Yingfei sometimes thinks that in addition to the relationship between culture and thought, I am afraid that the Chidao built by Qin Shi Huang is also one of the major factors.

……

Hearing this, Jiang Wan thought for a while, then turned towards Qin Gong Yingfei and said: "Qin Wei gallops in the world, the East is poor Yanqi, the South Pole Wu Chu, above the rivers and lakes, and the view of the coast is complete."

"Fifty steps wide, three feet and trees, thick outside, hidden with golden vertebrae, trees with green pine."

……

Speaking of this, Jiang Wan walked to the huge map of the Central Plains in the study, pointed at Xianyang with a wooden stick, and said: "Chidao takes Xianyang as the center, and goes east to the Qi and Yan regions, and south to the Wu and Chu regions."

"Generally speaking, the road is about 50 paces wide, and the road surface is firmly tamped by iron vertebrae, and it is turtle-shaped above the ground, and the slope formed is conducive to drainage."

"In order to facilitate the calculation of road mileage, according to the local conditions on both sides of the road, a tree is planted every three zhang, or green pine and willow, or acacia cypress and elm cypress, which stretches at intervals, which is spectacular and beautiful."

"At the same time, the road is three lanes, the middle is for the emperor's exclusive use, and no one else is allowed to use it without special permission, and the two sides are side roads, which can be used by the officials."

"At that time, the First Emperor ordered the construction of Chi roads throughout the country, and the five major roads were the most famous."

Hearing this, Qin Gong Yingfei still couldn't help but admire Qin Shi Huang's generosity, a Gaigu emperor like this is rare in ten thousand years.

Fifty steps is seventy meters wide, such a galloping road is simply terrifying, Qin Gong Yingfei knows very well, even the busiest national highway in later generations, it is only forty meters.

Four-meter one lane, Qin Shi Huang's gallop road, in later generations is a sixteen-lane super highway.

……

Such a far-sightedness and such a strategic vision, looking at the entire 5,000 years of China, I am afraid that only Emperor Yang of Sui, who dug the Beijing-Hangzhou Grand Canal, can be compared.

Because these two were tied together by land and water, they joined the formation of Chinese civilization.

……

The thought flickered in his heart, and a smile flashed in Qin Gong Yingfei's eyes, and he looked at Prime Minister Jiang Wan and said.

"Are the five major roads?"

……

Jiang Wan's statement was something that Qin Gong Yingfei had never heard, and he had only heard of the nine galloping roads of Shangjun Road, Linjin Road, Dongfang Road, Wuguan Road, Plank Road, Western Road, Straight Road and Binhai Road, not the five major roads.

Hearing Jiang Wan say this at this moment, Qin Gong Yingfei couldn't help but feel a little interested in her heart, and couldn't help but look at Jiang Wan.

Similarly, the same is true of the military advisor Guo Jia and the captain Xu Shu. The theory of the five major roads is easy to universalize, which aroused the curiosity of the three people.

Sensing the gaze of the three people, Jiang Wan smiled slightly and said, "Chidao is centered on the capital Xianyang, communicating the east, west, north and south of the Great Qin Empire, and radiating with other roads."

"There is the Longxi Northwest Tunnel in the west, the Sanchuan Donghai Road in the east, the Guangyang Road in Hanoi in the north and south, the Nanyang Nanjun Road in the southeast, and the Liaoxi Huiji Road near the Bohai Sea, extending in all directions, crisscrossing and criss-crossing."

The wooden stick in Jiang Wan's hand crossed the names of places one by one on the map, and said: "Longxi Northwest Tunnel, go west of the Wei River from Xianyang, pass Yongcheng and enter the northwest of Longxi." The branch road can reach Xitui and Dog Hill, cross Longshan, go to Jitou Mountain, the source of Jingshui, and then return to Xianyang along the Jingshui River Valley. ”

"The northern tunnel is all in the homeland of Qin, and this area is the ancestral place where the ancestors of the Qin people raised horses and gathered, and the area of Jitou Mountain is the birthplace where the Qin people were called by the king of Zhou and settled in Qin."

Taking a deep look at Qin Gong Yingfei, Jiang Wan turned the wooden stick in his hand and said, "The remaining four trunk roads are for the purpose of consolidating the new land of the Six Kingdoms."

"Among them, the Sanchuan Donghai Road, which runs from Xianyang along the east of the Wei River to Guguan, goes to the south bank of the Yellow River, passes through Luoyang, Sanchuan County, goes through Chenliu, passes through Dangjun, passes through Pengcheng in Surabaya County, and arrives at Qu County, Donghai County, which is the main transportation artery connecting the east and west of the empire."

Hearing Prime Minister Jiang Wan's eloquent talk, Qin Gong Yingfei's eyes flashed, looked at several place names crossed by Jiang Wan's wooden stick, and said: "Hangu Pass on the Sanchuan East Sea Road is the gateway in and out of the Guanzhong, and Xingyang is the fortress that controls the eastern part of the Guandong, and Pengcheng is the key point connecting Wei, Chu, and Qi."

"What the king said is very true, Sanchuan Tokaido has strengthened the connection between Xianyang and the Central Plains."

Prime Minister Jiang Wan complimented Ying Fei, and then his gaze fell on the map again, saying.

"Nanyang Nanjun Road, from the eastern suburbs of Xianyang along the Bahe River to the southeast, go Lantian, enter Shangluo, go out of Wuguan, pass through Wanxian County, Nanyang County, go south through the Jianghan Plain, arrive at the Jiangling area of Nanyang County, the avenue is here, and then go down the east along the big river, water and land are staggered, pass through Hengshan County and Jiujiang County, and arrive at the downstream Huiji, connecting the southeast of the empire into a piece."

"Guangyang Road in Hanoi, from Hanoi to the north, go to Anyang, to Handan, through the Dongyuan of Hengshan County, to Jixian County, Guangyang County, the avenue runs north and south across the North China Plain, parallel to the Taihang Mountain from east to west, extends east to the right Beiping County without end, and then arrives at the Jieshi area."

Jiang Wan, who was a little dry in the explanation, raised his head and took a sip from his cup, moistened his throat that was about to smoke, and continued.

"Hanoi Quang Duong Road is the main road of the empire's north-south traffic, Ji County on this road is the former capital of Yan State, Handan is the former capital of Zhao State, Anyang is an important place of Wei State, along Hanoi Quang Duong Road across the Yellow River into Sanchuan County, directly connected to Sanchuan Donghai Road."

"As for the Huiji Road in Liaoxi, it starts from the south of Liaoxi County in the north, and goes south through Youbeiping, Yuyang, Guangyang, Julu, Jibei, Linzi, Langya, and Donghai Counties, and reaches Huiji County."

"This trunk road can be connected to Liaodong from western Liaoning to the east, and from Huiji to the south, you can enter Fujian and cross the border."

……

"The prime minister is well-read and has a strong memory, and he really deserves his reputation."

……

Hearing Prime Minister Jiang Wan's exposition on the five major roads of Great Qin, Qin Gong Yingfei and others felt amazed in their hearts, and they had to admit Jiang Wan's erudition and strong memory.

Even this kind of thing recorded in the dossier is clear, which makes Qin Gong Yingfei moved.

……

The thought flickered in his heart for a while, and Qin Gong Yingfei looked at Jiang Wan and said, "Prime Minister, in addition to the northwest tunnel of Longxi, there is only the meridian road in my Qin country?"
