Coming out of the warehouse, Li Ke found someone to arrange it, Datang actually had similar warehouses before, but those warehouses were definitely not good at preventing rats, so Li Ke asked people to build a grain warehouse again.

For example, a large amount of grain is stacked, and the temperature of the grain center will become higher, especially in the summer when it is hot, so the construction of the granary is also particular, fortunately, Li Ke has books here, and the earliest granary construction in China is certainly not as advanced as the modern granary, and it must be step by step.

At the beginning, the granary reserve warehouse can not be as big as the modern granary, and it is necessary to build a smaller one, so that the problems of grain storage are easier to solve, such as the temperature and humidity are too high, and we must find a way to solve it to avoid germination, mildew, etc., which are very complicated.

Fortunately, he has a set of processes here, and combined with the actual storage experience of the Tang Dynasty, the ancients also have a lot of experience in this regard, and these experiences are not completely useless, because it is impossible for modern people to think of what kind of method is best under ancient conditions.

The combination of the two is the best.

At present, there are several reserve granaries near Datang, and the number of completed ones is not much, Li Ke simply explained to Tian Meng, and asked him to arrange a warehouse with spare space first, and said that he would place excellent grain seeds in this warehouse in the future, so that people could protect it first.

After doing this, Li Ke went into the palace to say hello to Fang Xuanling, and the promotion of this matter still needs the cooperation of the Ministry of Agriculture, or the Ministry of Land and Resources.

Originally, the name was the Ministry of Land and Resources, and Gao Jifu, the original Zhongshushe, served as the secretary, but later Li Shimin changed the name to the Ministry of Agriculture, because agriculture is very important in the Tang Dynasty, Li Ke doesn't care, anyway, there is so much work to do.

And some of the work of the Ministry of Land and Resources, there are indeed not so many in this era, and then the Ministry of Land and Resources listed it separately, and Gao Jifu is also in charge.

To put it bluntly, there is not so much work in this department now, and it can be done with the Ministry of Agriculture, but it may be useful in the future, so the department will be established first.

The delivery of these grains was not so fast, and it was estimated that it would take Li Ke almost a month one after another.

When Li Ke was making these preparations, Xizhou.

Li Daozong and An Xinggui received the news of the use of troops in the Western Regions at about the same time.

Seeing the order in his hand, An Xinggui took a deep breath, worthy of His Royal Highness the King of Qin, this pattern is big, either not moving, or moving, or targeting the entire thirty-six countries of the Western Regions.

The order was accompanied by a complete set of military maps.

Maps that have been improved and redrawn from modern maps are actually artifacts in this era.

More than a thousand years have not changed much for the big rivers, such as the major large mountain ranges, let alone a thousand years, and the estimated changes in the second zero are not so big. Of course, it can't be said that there is no change at all, but this change is reflected on the map, which is actually equivalent to no change.

Map of this era...... How to say it, people like Li Ke, who are not road idiots, also need a certain foundation to understand the maps of this era, mainly because they are too abstract, although there is already a concept of scale in Datang.

The earliest scale is in the Wei, Jin, Southern and Northern Dynasties period, from Pei Xiu of the Pei family in Hedong, which is the ancestor of Pei Xingjian.

However, although the Tang Dynasty people drew maps with the concept of scale, they drew a house at the location of the village and a peak at the location of the mountain, which was not reflected in terms of topography.

Unlike modern maps with contour lines, etc., Li Ke's maps naturally also have contour lines, which are completely similar to modern topographic maps.

Of course, it is also marked that there may be some discrepancies.

But the whole map is used...... In fact, it is much more accurate than the map of the Tang Dynasty!

It has a large error on small things, but its accuracy in the big direction is absolutely unmatched.

The reason for this is naturally the changes of more than 1,000 years.

Take one thing alone, the area of Qinghai Lake in Datang is about more than double the area of Qinghai Lake in later generations, although the approximate radius of Qinghai Lake seems to have increased much when you look at it from a high mountain, but the area has increased a lot.

The reason for such a large gap is naturally because the number of rivers flowing into Qinghai Lake is different. The current Qinghai Lake is much larger than that of later generations, and the rape fields by Qinghai Lake in later generations are now under the water.

An Xinggui read the entire map, and he knew it in his heart, but he didn't do it as soon as possible, but waited for Li Daozong to contact him first.

According to the order in the edict, Li Daozong must have received the order before him, after all, the distance between Xizhou is closer, and the connection between Xizhou and Longyou Dao is actually increasing.

In the last year alone, the caravan trade between the two has increased hundreds of times compared to before, and all kinds of goods are entering Longyou Road through Xizhou, especially in the direction of Dunhuang County.

Part of the goods flowed back to the interior of Longyou Road through Dunhuang County, and some went to the Western Regions. There is also through the Yellow River all the way to Jincheng, and then through Jincheng stretches to all parts of Longyou Road.

Therefore, An Xinggui knows very well that Xizhou is much richer than their Longyou Dao now, not to mention that it is a place arranged by His Royal Highness King Qin?

And in this order, the most important thing is to make the army dispatched this time mainly the army of Xizhou, supplemented by the army of Longyoudao.

Why? Naturally, it was a difference in quality.

The reform of the military system of the Tang Dynasty, Longyou Dao has naturally been restructured, and the current government soldiers of the entire Longyou Dao are only 35,000 people, but they are basically all elite. Some of the older ones retired and returned to the local area to become officials of the Datang Public Safety Department.

Coupled with the special location relationship of Longyou Dao, the total number of government soldiers in Longyou Province was about 50,000 before, but now there are only 35,000 government soldiers, but the local security department officials have increased to 50,000.

The extra 50,000 officials just allowed the more than 30,000 government soldiers to no longer bear the responsibility of the security work of the town, and only a small number of city defense troops were retained, and then most of them could be arranged to the border. On the contrary, it strengthened the strength of Longyoudao.

You must know that in the past, the 50,000 soldiers of Longyou Road could only be concentrated in Dunhuang and other border areas, and the northern border was about 10,000, and the remaining 20,000 were distributed in various locations in Longyou Road.

Now, although the configuration is similar, for example, the more than 20,000 provincial soldiers concentrated on the western border are not distributed in various towns, but are concentrated in the army camps, and the ability to respond to emergencies has naturally improved.
