Jin Liang couldn't help but sigh: "If the Great Wall is like a shield that is blocking horizontally, then Qin Zhidao is a spear that pierces straight out; If the Great Wall is a bow that is drawn, then Qin Zhidao is an arrow that is about to fly out. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo”

Jia Xu stroked his palms and smiled: "Lord, wonderful, your analogy is appropriate, Qin Shi Huang used a straight road to revitalize the entire defense posture, from the original passive defense to active defense, if it wasn't for Qin Shi Huang's early death, the Great Qin Empire would have wiped out the Huns a long time ago." ”

Jia Xu went on to explain the benefits of rebuilding the straight road, which will not only have the effect of military deterrence, but will also play an extremely beneficial role in the unification of government decrees between the north and the south, economic development, and cultural exchanges.

Jia Xu cites the story of the Qin and Han dynasties to illustrate that Qin Shi Huang immigrated to the north of the Wuding River on a large scale in the 33rd and 36th years of the Qin Dynasty, and in the second year of Yuanshuo, the fourth year of Yuanjia, and the second year of Shiyuan of the former Han Dynasty, he also implemented military tun and mintun in Shuofang four times. The Qin and Western Han dynasties implemented these immigration measures, all relying on the straight and galloping roads from Xianyang and Chang'an to Shangjun. After Juntun and Mintun, the areas inside and outside the Great Wall, which were originally based on "animal husbandry as the world's rao", were called "Rao Valley" and "Many Animals", and the population of Shangjun reached more than 600,000 at that time, which was more than the developed Hanzhong County.

Jia Xu smiled and said, "My lord, if you want the people of other states and counties to develop the Hetao faster, you'd better rebuild the straight road." ”

Jin Liang ascended high and overlooked, the straight Qin straight road has been vertical and horizontal to the south, if like a yellow dragon, Jin Liang looked back to the north, the Great Wall on the Yin Mountain is like a dragon, the Great Wall, the straight road if the two dragons are closely coordinated, will be able to restrain the Saiwai Hu people to the Han border prying eyes, how can the Eastern Han Dynasty court be different from the Western Han Dynasty, there are many family ministers to control, more negative defense, after giving up the Great Wall and the Yellow River, the straight road has become an ordinary road, and it has been in disrepair for a long time, the road is overgrown with grass on both sides, and some places begin to collapse.

Jia Xu's introduction to the straight road made Jin Liang can't help but have the ambition to chase after the Qin Emperor far away, but he thought of a key point, frowned and asked: "Wenhe, the straight road is Chang'an, Chang'an is now under the control of Dong Zhuo, we have repaired the straight road, and it will only cheapen Dong Zhuo to encroach on our rich Hetao, and this straight road is a north-south connection, but it does not lead to Jizhou, although the straight road is good, we can't use it now, there is no need to repair it." ”

Jia Xu laughed loudly: "My lord, although Chang'an is now under Dong Zhuo's control, Dong Zhuo is now surrounded by enemies, the east is the Kwantung princes, the south is Yuan Shao and Yuan Shu's brothers, and the west is Huangfu Song, Ma Teng, and Han Sui, and we are eyeing him in Bingzhou and Jizhou, how dare he move people to invade the Hetao, and the day when Dong Zhuo's Xiliang army will be divided is not far away." ”

Jin Liang was shocked and asked, "You said that Dong Zhuo's forces will split?!" ”

Jia Xu smiled and said: "Dong Zhuo holds more than 100,000 Xiliang Iron Cavalry, vertical and horizontal, unstoppable, but he is a complete idiot, he can't see himself clearly, he thinks that if he works hard to please those ministers of the family, he can let them cooperate with him wholeheartedly, but he doesn't know that those ministers of the family regard the views of the family above all else. Never willing to let a cold martial artist rise to the top, it turned out that the heroes begged Dong, so that those ministers of the family in Luoyang were united with Dong Zhuo. Now all the princes are taking care of their own development, and there is no strong enemy oppression, and the minds of the people in Luoyang City have changed. The dark tide is surging, Dong Zhuoyi's son Yan Xing has been at odds with Dong Zhuo's generals Li Dao, Guo Yan, Zhang Ji and others, and the battle between the two sides is becoming increasingly fierce, and within a year, there will be chaos. ”

Jin Liang thought of the serial scheme in history, and couldn't help but have a mysterious smile on his face, and laughed: "What Wen He said is very true, then let's wait for Luoyang to become chaotic!" ”

Jia Xu said again: "Lord." As for the Hetao and Jizhou Xiangyang, limited to Taihang, Jinliang blocked the road, we can not build a straight road, but we can build a straight road, the road is connected with the straight road, along the gallop road soldiers and horses to the Hetao, along the straight road. Chang'an can be attacked in the south, and Xianbei can be attacked in the north. ”

Although Jin Liang himself is quite literate, he only knows a little about the history between the Three Kingdoms, and he doesn't know much about some things between the Qin and Han dynasties, while Jia Xu is not only quite resourceful. He is also a well-read person, and the sons of the pre-Qin Dynasty know everything, so he can put forward a ruthless move in military and political terms.

After Jia Xu's introduction, Jin Liang had a deep understanding of Chidao, and he suddenly found that the straight road was like the highway of later generations, and the Chidao was like the railway of later generations.

In the second year after Qin Shi Huang unified the six countries, he ordered the construction of a gallop road centered on Xianyang and leading to all parts of the country. The road is in a flat place, the road is fifty steps wide, a tree is planted every three zhang, the two sides of the road are rammed with metal cones to build thick, and the middle of the road is the part dedicated to the emperor's patrol car.

Jia Xu is good at meeting the wishes of the emperor, and naturally understands that Jin Liang is a very pragmatic master, unlike Qin Shi Huang, who is happy and self-conscious, so he smiled and said: "This Qin Chidao is just used as an emperor to go out on patrol, in fact, it can be used for military purposes, to transport military supplies and infantry to rush to the front." ”

Jia Xu led the way in front and led Jin Liang to a gallop road.

Jin Liangfei dismounted, came to the gallop that was already a little broken, squatted down, and carefully observed the construction of the gallop road.

Jin Liang took a closer look, and this galloping road, which had long been abandoned in the Eastern Han Dynasty, actually surpassed the advancement of this era.

This Qin Chi Road is an ancient "track", the principle is no different from that of modern railways, it is also a double line, but it is not a train pulled by a steam locomotive, but a carriage pulled by horsepower; Paving on both sides of the road is not the railroad track, but the wood, the wood material of the track is hard, and after anti-corrosion treatment, although after more than 400 years of wind and rain, so far intact, but the sleeper has been decayed, obviously not after anti-corrosion treatment, the material is not as hard as the track wood, but it can also be seen its general appearance. The roadbed is rammed very strongly, and the sleepers are laid on the roadbed.

Jia Xu picked up a sleeper and handed it to Jin Liangdao: "Lord, you see, the material of this sleeper is relatively soft, not only to reduce labor, nor only to open up a wide range of wood sources, but the craftsmen of the Qin period consciously selected, the softer sleeper can be closely combined with the rammed very hard roadbed, so that the track is stable, and the car can run quickly and smoothly on it." ”

Jin Liang smiled and nodded, he felt more and more that many good things in the Qin Dynasty were abandoned by the Han Dynasty, and it was worth picking up those good things again, such as straights, such as galloping, such as the standardization of weapon production, in the Qin Dynasty, the military industry has been very developed and scientific, and has achieved standardization, serialization and generalization, the craftsmen of the Qin State make sixteen million identical arrows every year, and the crossbows they manufacture are exactly the same as modern rifles, and even the appearance of the parts is completely similar to that of rifles, Moreover, its production is also standardized, serialized and generalized, and any part can be installed by picking it up.

Jia Xu smiled again: "Lord, you see that the distance between the sleepers of this gallop is just the right distance, and it is said that it is just in line with the horse's steps." Once the horse is on the track, it can't help but run fast and can barely stop. Every thirty or forty miles, there is a horse station, and the people at the horse station fill the wood between the sleepers to level it, and there are many horses waiting here, all of them are fed there, and they are well rested, and once necessary, they can gallop on the cart, and the horses will not stop, and when they reach the next horse station, because the sleepers have been filled and leveled, the horses can gradually slow down and stop, and replace them with another well-fed and rested horse, and continue to gallop forward, so that they can reach a very fast speed. This was the most economical use of horsepower, and it was said to reach at least a thousand miles in a day and a night, which was faster than a cavalry gallop. ”

Jin Liang's eyes widened when he heard that he could reach such a speed on the gallop road, which was far beyond the technical level of this era, and said: "It is no wonder that Qin Shi Huang can effectively manage a huge empire without dividing the feuds, and he can often carry out large-scale operations of hundreds of thousands of people. ”

Jia Xu said again: "My lord, you have strongly advocated four-wheeled carriages before, which are more stable and heavier than two-wheeled carriages, and are especially suitable for running on galloping roads. The ride is smooth, there is less friction between the ride and the wheels, and the horse-drawn carriage is less strenuous to pull up the carriage, allowing more people or more goods to be pulled at a time. ”

Jin Liang smiled and remembered that Ma Jun had added iron rings to the axles of the four-wheeled carriage in recent days, so that the iron rubbed against each other, and grease lubrication was added in the middle, which enhanced the firmness of the wheels, reduced the friction of the car bearings, and made the service life of the carriage longer.

Jin Liang had a question and said unhappily: "Why is such a good road abandoned in this dynasty?" ”

Jia Xu said with a stunned face: "In the last years of the Qin Dynasty, the people's livelihood withered, there was a serious shortage of horses during the founding of the country, and even the emperor was unable to equip his imperial chariot with horses of the same color. And there are no cars running on the gallop road, but it obstructs traffic, so Qin Shi Huang worked hard to build the gallop road, some of which were destroyed in the war, and most of the rest were also demolished after the war and became ordinary roads. The national strength of our Han Dynasty only recovered after a long time, and the long-term implementation of Huang Lao's learning and inaction rule, so there has been no labor and mobilization to rebuild the Chi Road, plus the Qin Dynasty's Chi Road is too wide, and later many roads were reclaimed for arable land, narrowed, or even completely ceased to exist.

Also, the Qin Dynasty Chidao was used for long-distance transportation, and our Han Dynasty had been divided into princes for a long time, and the people everywhere had no need for long-distance transportation, and the transportation line became shorter, so it lost the need to build Chidao. ”

Speaking of this, Jia Xu said with a solemn face: "Lord, you have been trying your best to fight the scum in the clan and abolish those counties, I believe that you don't want the Liu Han royal family to engage in any more feudal system, and you have the ambition to expand the border, whether it is military or civilian, Chidao can come in handy." My lord, don't say anything about it, your determination to rebuild the gallop has been decided. ”

Jin Liang patted Jia Xu on the shoulder with a smile and said, "Cultivation will definitely be cultivated, but we have a lot of places where we spend money now, and the people have just stabilized. ”

Jia Xu smiled and said: "Lord, for the time being, we don't need to repair all of Qin Chi Dao, we only need to build a new one and rebuild one."

The Chi Road built in the Qin Dynasty mainly includes the Oriental Avenue of Xianyang out of Hanguguan along the Yellow River through Shandong Dingtao and Linzi to Chengshanjiao, the Northwest Avenue from Xianyang to Lintao in Gansu, the Qinchu Avenue from Xianyang to Jiangling in Hubei Province through Wuguan in Shaanxi Province and Nanyang in Henan Province, the Sichuan-Shaanxi Avenue from Xianyang to Bashu, in addition to the Jiangnan New Road in the south and Shuguang in the south, and the Jiangnan New Road in the southwest to Guilin, Guangxi, and the Northern Avenue from Jiuyuan to Jieshi in Hebei along the Great Wall in the east.

We don't need to build a new road to the Hetao, we only need to build a road from Xiangyang to the Northern Avenue, from this north-south road to the North Avenue, and then turn to the North Avenue, to reach the place where the North Avenue and the straight road are connected, and then cross the north and south of the Loop. ”

Jin Liang asked Jia Xu to take out a large map north of the Yellow River, pointed to the route Jia Xu said with his hand, and couldn't help shaking his head and said: "This gallop road from Jizhou to Youzhou does want to be built, but if you go to the Hetao along this gallop road, it will go around a big circle, it is better to build another one across Taihang, Jinliang, from Xiangyang straight to the Hetao of the gallop road, this gallop road through Shangdang County Zhihuguan, Hedong County Beiqucheng, Shangjun Diaoyin City, Beidi County Qingyang City, Anding County Linjing City, with this gallop, you can remotely control Shangdang County, Hedong County, Shangjun, Beidi County and Anding County are not afraid of Dong Zhuo, Ma Teng, and Han Sui peeping into the rich Hetao."

Jia Xu frowned and said with a wry smile: "Lord, this gallop road not only has to cross the Taihang and Jinliang mountains, but also cross the Yellow River, and there are countless hills and rivers in the middle.

Jin Liang sighed in disappointment, after all, this is the end of the Eastern Han Dynasty, different from later generations, some leaders in later generations patted their heads, the moat must change the way, Jin Liang is to think about the great success, but also must comply with the technical conditions of this era, can not be forced

Looking at the lord's disappointed face, Jia Xu hurriedly smiled and said: "Lord, although we can't build a complete gallop road, we can build it in sections, and we can take a detour where we can't cross, anyway, the horses also need to rest, and the horses must be changed in the middle, and the gallop road doesn't need to be so complete."

Jia Xu lived in Beidi County all the year round and was very familiar with the terrain north of the Yellow River, so he roughly marked on the large map those places that could be built with a little leveling, and where the routes were to be detoured, very similar to the strands of later generations

Jia Xu smiled and said: "Lord, don't look at these routes are fragmented and twisted, but the carriage can travel fast between each section, even faster than the progress of the general cavalry After the completion of the construction of these sections, from Xiangyang to Beidi County, it can be reached in ten days, and before that, it will take at least a month, which is enough to save twenty days."

For the army, time is victory, and it can change the outcome of a battle in a few days, not to mention that it will be almost twenty days, Jin Liang happily ordered to rebuild the Qin Straight Road, rebuild the Northern Chi Road, repair the Chi Road from Xiangyang to Gaoliu City in Youzhou Dai County, and repair the Chi Road from Xiangyang to Linjing City in Anding County

Jia Xu pointed to the straight road and said very excitedly: "Lord, it's unbelievable to say that this Qin straight road began in the thirty-fifth year of Qin Shi Huang, and before September of the thirty-seventh year, it was a carriage and horse avenue with a length of 1,800 miles and a width of about 18 zhang built along the mountains and desert grasslands, and it only took two and a half years to complete the tasks of line selection, line change, construction, and construction of post stations."

Jin Liang understood what Jia Xu meant, and wanted him to follow Qin Shi Huang's example, recruit people, and repair the straight road and gallop road as soon as possible

Jin Liang shook his head and sighed: "Emperor Qin is so happy, seeking full blame, sparing no matter the people's strength, he can naturally make a thing in the shortest possible time, and we want the Han Dynasty to prosper, and we don't want the Han Dynasty to die in our hands, then we must be sympathetic to the people's power, and we can't requisition these roads are to cross mountains and rivers, the project is huge, the task is arduous, and it cannot be completed in one and a half years, and it is barely a prototype in three years, with a period of five years."

Wenhe, you said that you can build in sections, then we will build together from the end point, and use a section after repairing, and use it while repairing"

After Jin Liang and Jia Xu made a five-year plan to build a straight road and a gallop road, Jia Xu reminded: "My lord, if you want the road to play a role, you must issue a decree and strictly enforce the same track of cars."

"Cars on the same track?" Before that, Jin Liang could understand Qin Shi Huang's book and text, unified currency, and unified weights and measures, but he did not understand the "car on the same track".

Later generations that Guo Moruo once said that the car on the same track is a unified social system and customs, now it seems that it is absolutely far-fetched, and there are some people who interpret the "car on the same track" as the distance between the wheels must be the same, although this is in line with the literal meaning, but it is also difficult to explain Jin conscience, on the modern highway of later generations, various types of car wheel spacing are different, and there is nothing wrong with it, why the Qin Dynasty must use the same wheel spacing? Moreover, Qin Shi Huang's own chariot was pulled by six horses, which obviously would not be the same as the wheel spacing of an ordinary one- or two-horse horse-drawn chariot

Jin Liang is now standing on the Qin Chi Road, the original questions about the "car on the same track" have all disappeared in fact, in the Warring States Period, the other six countries also built similar roads for their own transportation convenience, just like the later Republic of China period, all the warlords also built their own railways, and set the width of the railway according to their own needs, so that the trains in other places could not drive to their own territory, and then liberated, the country was highly unified, and all these unreasonable phenomena were eliminated. The national standard railway gauge is 1435mm. After Qin Shi Huang unified China, the same track of the carriage was the distance between the two tracks of the unified gallop road, so as to determine the distance between the wheels of the carriage, and the distance between the two axles of each car was equal, and the carriage in the whole world could be driven to any gallop road, which was convenient for transportation

Jin Liang dictated, Jia Xu added, by the secretary Ling Lu Cui's handwriting, to the Xiangyang Imperial Court, requesting the rebuilding of the Qin Straight Road, Qin Chi Road and the resumption of the law of the same track, the chapter said that the rebuilding of the Straight Road Chi Road to the military and the people of the great significance of the brief and concise exposition (to be continued. )
