"Chen Niang, write it down, in the future, I will catch the noble woman of Western Xia, and I want to leave a young and beautiful one for this big brother, his kind of mind must be worthy of a decent daughter-in-law. The Song people don't dare to arrest you, get a Xixia woman general, and only teach Chinese when you have a child in the future, who dares to say that he is not a Song person! ”

For this request, Hong Tao agreed very seriously, everything that can be recorded in Chen Niang's small book is the most important, and its credibility is second only to the holy decree in the eyes of the soldiers of the new army.

With skis that can climb the slopes, Jiang Erlang's special forces are equivalent to another pair of wings, even if they encounter extremely complex terrain that cannot be passed by the sleigh, they can move forward lightly. And the travel speed is not much slower than that of a sled, and it is certainly much faster than walking on foot, which is very suitable for large-scale maneuvering operations.

Not only can the special forces use skis, but the new army also makes it a standard equipment in winter, and pays to give priority to purchasing large quantities of horse skins from the pioneers in Liangzhou and Mawei City.

In the future, this practice will also become a common practice, and all large-scale purchases by the Huangzhou military must give priority to pioneers, and those who are insufficient will be obtained from other channels, which can be regarded as a kind of policy tilt.

"What do you three think of this big ship?" After arranging many things such as rinsing, Wujin Xing, and expanding the new city, Hong Tao began to do his business again.

He built a very strange sled, and the strange thing is that it was not pulled by dogs, nor by camels, nor by any kind of animal power, but by a sail and driven by the wind.

In addition to the children's group transferred from Huangzhou, there were three new members who took the lead in boarding this sled. They were the nephews of the crown, and they were brought to Liangzhou by Wang Hao to be apprenticed to the horses, specializing in learning the magical art of navigation. This is also one of the conditions of the contract that Hong Tao made with the crown, which must be completed.

Hong Tao didn't plan to lose his promise, this wind sled was actually specially designed for these three children. There is no sea in the northwest, and even if there is a lake, you can't build a big boat, so how can you learn navigation without a boat?

Hong Tao has the most ideas, so he simply uses a sled to make trouble. This thing shouldn't be considered a sled, it should be called an ice sled. It has no skis and three extra steel skates underneath.

In fact, in principle, sleds are the same as boats, and the key to navigation is not whether you step on the board or the ice, but in the knowledge of algebra and geometry, and the key is the star map.

Since he wanted to learn new knowledge, Hong Tao didn't plan to teach only these three children, but simply transferred the children's group under Xu Donglai, and dozens of children got together to learn more efficiently.

Most of these children are already members of the third group of children's groups, including the Tibetan, Qiang, and Uighur ethnic groups, while there are not many children from the Han family, and they are generally older than the children of the first and second groups of children's groups.

Due to the influence of the first two batches of children as seniors 24 hours a day, their growth rate is not only not slow, but faster.

The three children of the Wang family are not young, two are nine years old and one is ten years old, and Hong Tao simply incorporated them into the third batch of children's groups in order to save worry. This did not violate the agreement with the crown, and he only promised to teach navigation at the beginning, and did not say that he would teach it alone, let alone stipulate whether he needed to endure hardship.

In fact, the ancients did not spoil their children so much, even if the descendants of rich families sent out for apprenticeship, they are no different from children from poor families, and there are too many hardships to endure.

Where to find ice? This is not easy, the west of Liangzhou City is the Shiyang River. This river originates from the Qilian Mountains in the southwest of Liangzhou, and is more than ten meters wide when passing through Liangzhou City, and the water volume is quite large but the flow speed is not particularly fast, and it goes north very gently.

This is a small 300 miles, deep into the Gobi and desert in the north, and also formed two small lakes. There Hong Tao followed the order to go once, the scenery is very good, gathered a lot of wild animals and water birds, if you don't pay attention to the nearby desert, you will suddenly come to the south of the Yangtze River.

In fact, the area south of the Alxa League in the Song Dynasty was not full of deserts as in later generations, and there were many swamps and oases in between. It's just that with the increase in population and climate change, water sources are becoming less and less, and swamps and oases are slowly disappearing, leaving only the vast desert.

Animals know how to come to live in these oases and swamps, and people naturally know that many Western Xia herders who fled from Liangzhou used these places as temporary shelters.

They are reluctant to leave the treasure land of Liangzhou, people are cheap when they leave their hometowns, as long as there is still a glimmer of hope, they want to see more changes in the future. In case the Western Xia court sent troops to snatch Liangzhou back, they would be able to continue to live on this land.

It's a pity that what they are waiting for is not the Western Xia rescuers, but the special forces of the Song Dynasty led by the liking. With the existence of this Western Xia rebel general, many secrets that were not known to the Song army became public information.

Coupled with the elusive special forces, only a few herders fled into the depths of the desert, and most of them became captives, and only one fate awaited them, coolies and miners.

With the ice, the wind is easier, and everything may be lacking in the winter in the Northland, but there is no shortage of wind, and it is very many and fierce. The sleigh was halfway up when the wind blew and slid up, and the twenty or so children sitting on it were as if they had no weight, and they were sliding faster and faster.

The cold wind and snowflakes could not stop the enthusiasm of the children, they had never experienced this feeling of galloping like a fast horse without effort, and their little faces were blown red and still refused to turn their heads to avoid the wind, and they grinned and giggled.

To demonstrate the effect of a sextant, it is necessary to move long distances to be obvious. So the slide lasted most of the day, and it was not until the sun set in the west that the sails were retracted, and a makeshift camp was set up in a leeward place by the river.

Today's itinerary is basically here, according to the plan, tomorrow will go north for half a day, and you can return to the city after measuring the data of a few points along the way.

Hong Tao took the children out not only to demonstrate the effectiveness of the sextant, but also to do a simple survey of the river, and then use the data to redraw the map around Liangzhou to prepare for the future.

This work is not only done by Hong Tao, but every day a small team of youth league members will go out to map a small area and collect the data to Hong Tao.

But it was not the youth league that provided the most data, but Fu Ji's camel caravan. They measured wherever they went, and in the past two years, they have persevered and traveled almost all over the northwest border area.

Don't look at Hong Tao didn't go through all the mountains and rivers basins in Huangzhou, but he can say very responsibly that there are really few people in Huangzhou who know the terrain as well as himself, which is called knowing the world without leaving home......

Of course, it is a bit of a blow to say that the world is blowing now, but it will not be long before we can know the Central Plains, the north and the south, and the entire East and Central Asia regions.

These groups of children are their own eyes, legs, and hands, and what they can see, walk, and touch is, to a certain extent, equivalent to their own experience.
