After saying this, Li Yuan felt that the burden that had been pressing on his shoulders these days suddenly lightened, and his heart felt a lot lighter. In the past few days, for the sake of the displaced people, he has thought of a lot of things with reference to the later generations, but it is difficult to do it if it is simple.

For example, in the Wenchuan earthquake in 08, the slogan at that time was "When one side is in trouble, all sides will support." "Countless supplies were shipped from all over the country, but that was due to the convenient transportation environment of later generations. One of the reasons why Yang Guang repaired the Grand Canal was to solve the problem of north-south transportation, but even if there was a Grand Canal, the road from Luoyang to Chang'an was mainly transported by land.

The characteristics of land transportation are very slow, and it will consume a lot of manpower and material resources, for example, from Luoyang to Chang'an to transport three stone of grain, may arrive in Chang'an only one stone of grain.

But when Li Yuan said this, instead of seeing half a shock on Li Shimin's face, he was full of suspicion.

"Father, you don't want to entertain so-and-so." Li Shimin couldn't laugh or cry, his suspicious eyes turned to Li Yuan, and asked, "Could it be... Father, are you old and confused? As the saying goes, open source and reduce expenditure, Chang'an's grain is a fixed amount, so before the grain from other places arrives, Taicang can use this bit of grain. As for saving resources, Fang Xuanling and others have always been reliable, and there are precedents for disaster relief in the past...... Father, what can you do to save those 200,000 displaced people? I can only do my best to keep more people from starving. ”

Li Yuan snorted disdainfully, his face unchanged. There is a brocade box on the desk against the wall on the east side of the warm pavilion, and the brocade box is about half an arm's length for adults, and the width of the palm is about about that. The delicate lock on it was opened with a 'click', and there was no strange treasure in it, but a piece of paper, on which a pattern resembled the rails of later generations was outlined with very thin ink lines, but on the rails was not a steaming train, but a four-wheeled carriage drawn by several horses.

"It's... What is it? The painting is so fine, it is much more vivid and lifelike than the painting of Yan Lide, the secretary of the Ministry of Industry (Yan Liben's elder brother), these horses are vivid, the neighing sound seems to sound in the ears, and every silk and hemp of the reins held by the driver is also drawn..."Li Shimin touched this piece of thin paper, couldn't put it down, and said in amazement.

"Nonsense, this is a photo, how can it not be realistic!" Li Yuan rolled his eyes, despising Li Shimin, an ancient man who had lived for a thousand years. If he had seen the illustration of the plum in the golden vase pressed under the bed, wouldn't he...

This railway photo is nothing else, but a photo attached to the appendix of "On the Economic Crisis of 1935~1942 in the United States" purchased by Li Yuan. As for why there were already steam trains in the United States in the forties of the twentieth century, but the appendix was a photo of a four-wheeled carriage galloping on the railway, which Li Yuan also felt strange.

"By the way, Father, what the hell is this painting?" Li Shimin couldn't put it down and rubbed it carefully with his hands, and the smoothness of the surface of the photo like oil paper seemed to him to be very novel, and Yan Lide, including his younger brother Yan Liben's paintings, could only be appreciated, but could not be used to touch them often, which was undoubtedly a defect in the eyes of Li Shimin, who was a bit of a literary fetish.

"The carriage in the painting is called a four-wheeled carriage, but that's not the point, this is the railroad track, and the wheels of the carriage are interlocked with the railroad tracks, and the carriage is running on the ground." Li Yuan pointed to the things on the photo to explain to Li Shimin, thought about it and said, "Shimin, do you know the way to transport grain in the Qin period?" ”

Li Shimin was stunned for a moment, and then said: "The first emperor in the "Historical Records" has written in this chronicle: from the pole temple road to Li Mountain, as the front hall of Ganquan, to build Yongdao, from Xianyang belongs to it. ”

A corridor refers to a passage between buildings with a covered roof.

During the Qin Dynasty, the Yongdao was built on both sides of the grain transportation route, which played an important role in the battle to destroy Chu.

"Isn't the Qin Shiyong Road and this railway similar? Building railway tracks to allow four-wheeled carriages to pass quickly can save the time spent transporting grain, so how can 200,000 displaced people not be saved? Li Yuan stroked his beard and smiled.

Li Yuan slumped the photo of the railway on the desk, and carefully talked to Li Shimin about the various wonderful uses of the railway, as well as the difficulty of construction, the cost of it, and so on.

"Wonderful! Wonderful! Li Shimin slapped his legs and laughed, and walked around the warm pavilion of Da'an Palace, the excitement between his eyebrows was obviously unbearable.

From now on, if there are natural and man-made disasters in the Tang Dynasty, relying on the convenient transportation of this railway, there will obviously be fewer people starving to death than in the previous dynasty, which is a great good governance.

This move is good for the future, and it is also good for the present, and there is no need to worry about the same tragic ending as Yang Guang, how much money can it cost to build a railway? It is obviously more expensive than digging the canal from Yangzhou to Youzhou, and it also saves people's manpower.

Now as long as the railway from Luoyang to Chang'an is built, these 200,000 displaced people can be properly arranged, and when the time comes, his Li Shimin's throne has the support of the people of this part of the people, and it is not as stable as Mount Tai?

As for Li Yuan's role, Li Shimin completely ignored it, as long as he, Li Shimin, didn't mention it personally, who could know that this railway policy was proposed by the Emperor Taishang, who lived in the deep palace!

"Although copper is needed for the laying of the railway, it is only a layer of copper on the surface, and wood can be used in other places," Li Shimin muttered.

According to his father, steel is the best for railways, but he firmly denies it. Datang's annual steel output is extremely low, and good steel must be used on the cutting edge. Although the food problem of 200,000 displaced people is very urgent for the Tang Dynasty, it is the Turkic people in Mobei who are even more urgent.

Jieli Khan could raise 100,000 Turkic elite horsemen to the south at any time, and if it were not for his usual great military exploits and prestige in northern Xinjiang, Datang would not have the Weishui Alliance to scare off the Turks, and could only move to Jinling like the Jin Dynasty in the past, and the north once again became the pasture of the nomads.

"But... Now that the northern part of Guanzhong is in turmoil, the world has just been decided, and the people are in the ascendant, if they are conscripted and conscripted..."The smile on Li Shimin's face suddenly stopped, but there was a faint sorrow.

It is a fact that the cost of building a railway is much lighter than that of the Grand Canal, but the current nine years of Wude are not as good as the great cause years of the Sui Dynasty, let alone Guanzhong, which has just experienced a military disaster!

Xing, the people suffer; Death, the people suffer.

Although Li Shimin didn't know Zhang Yanghao's first song, he didn't know that the sentence "The palace was made of soil" also referred to Taiji Palace and the Daming Palace he built.

But his understanding of the eight characters is beyond the ability of ordinary people, otherwise he would not have had four years of recuperation before launching a war of extermination against the Turks in the fourth year of Zhenguan.

But Li Yuan had already prepared in his heart, looked at Li Shimin fixedly, and said in a deep voice: "Work for relief!" ”
