"Well, in this way, I'll bring it over, Xu San and they're over there, I'll let them carve it out." Huo Gang nodded, and soon he really needed a seal.

After these Turkic tribes migrate, it is estimated that most of the time they will not be nomadic and will definitely be sedentary, and as long as there is sufficient pasture and water for grazing, they do not necessarily need to migrate.

"Yes, does the general have anything else to explain?" Wu Ping immediately asked.

"It's basically gone, for the time being, we are safer here, and after I take the Yiwu country, our entire territory will be on the right track, and at present, we will be safe in the next year or two." Huo Gang nodded, "Mr. Wu, what you need to pay attention to is to cooperate with Anno to register our population, and the next time Zheng Ning and them bring some paper, it is equivalent to when the Luo Department migrates, including these Turks, they need to be registered." ”

"Yes, the old man understands, general, please rest assured." Wu Ping nodded immediately.

"In addition, there is one more thing, Mr. Wu can teach them some words in his spare time, at least basic literacy must be achieved." Huo Gang thought for a while and said.

"This ...... General, it's not that the old man is unwilling, but there are too few people who can be gentlemen now, although almost all the people on Anno's side are literate, but their literacy rate is not very high, and it is unlikely that they want to teach others. Wu Ping smiled bitterly, he could, but he also had a lot of things to do now.

"Well, okay, then I'll write a set of books for you to teach." Huo Gang thought about it, this could only be him.

As for what method, it must be the Chinese pinyin of later generations, in fact, there is pinyin in this era, and the ancients also gave Chinese characters phonetics, but this kind of phonetic pronunciation is to use Chinese characters to phonetize Chinese characters, also called straight phonetic method, but this method has great limitations.

In fact, after getting Hanyu Pinyin out, it is conducive to the promotion of Chinese, because the number of Hanyu Pinyin letters is relatively small, and the basic alphabet is only twenty-six, which is very simple to learn. Even for some ordinary people, it is easy to memorize these 26 letters, as well as initials and finals.

After memorizing all of these, mark all the Chinese characters directly in pinyin, even illiterate people can read this character.

Chinese is too difficult, but many people know the charm of Chinese, if Huo Gang wants to popularize Chinese, then he must simplify the way of literacy, it is too difficult to read in ancient times, the strength of the major dynasties in ancient China can be said to be the strongest in the world, but it is still impossible to popularize knowledge, so you can know.

Of course, the high cost of paper is also one of the reasons.

However, Huo Gang proposed some solutions, and the craftsmen had ways to solve them, but this Chinese pinyin was only able to solve it by Huo Gang.

And there is another reason that in the future, it should not be said that the number of foreigners under Huo Gang's command is much more than that of the Han people, so in order to popularize Chinese, it is necessary to get this pinyin out.

"Yes." Wu Ping didn't say anything, even if writing a book in this era is a very sacred thing, but Wu Ping didn't question Huo Gang, in Wu Ping's heart, he really treated Huo Gang as an immortal.

After the explanation, Huo Gang left Yumen Pass, he was going to go to the limestone mine, he went directly to Yiwu country, the limestone mine is estimated to be with Luo Bu in a few days, Huo Gang will deal with the affairs of Yiwu country first.

After rushing to Yumen Pass, Huo Gang also explained the transaction to Anno's side, and went to the mining area, mainly because the cement in the first furnace could be calcined out immediately.

The speed of the construction of the new cellar furnace is much faster than Huo Gang imagined, and it will be completely completed in just seven days, and Huo Gang does not need to give an opinion on the style of the cellar furnace, because after asking Sun Er and them, Huo Gang knew that limestone was already fired in this era, and the experience of the cellar furnace was also very pure.

Firing cement is similar to firing lime, and there is no difference between the cellar furnace.

By the time Huo Gang arrived, they had already finished making the cellar furnace, and they were waiting for Huo Gang's next arrangement.

"Sun Er, you have to record the proportion of the next firing, fifty percent of the clay, fifty percent of the limestone, and then grind it into powder, add water and then calcine it into clinker, and after it comes out of the oven, mix about two percent of the iron-making slag and grind it together to become a powder, and the calcination time is about a quarter of an hour." Huo Gang gave an approximate ratio, the exact cement ratio Huo Gang didn't know, he just knew an approximate proportion.

But the proportion is not important, the important thing is to know the method.

"This ratio is not fixed, and later in the firing process, you can use different ratios of clay, limestone and slag, and then test the strength after the firing is successful."

"Yes, my subordinates understand, but what is this that the general fired?" Sun Er asked with some curiosity.

"Cement." Huo Gang didn't bother to change the name or something, but directly said its original name, "As for its function, we will know it after you burn it." ”

"Yes!"

The stone mill next to it and so on are all ready, Sun Er and they directly began to execute according to Huo Gang's order, and the calcination time of a furnace of cement only takes about a quarter of an hour, of course, this time Huo Gang also estimated.

Because modern cement calcination will definitely not take such a long time, but the temperature of this cellar furnace must not reach the temperature of modern specially fired cement converters, so Huo Gang added time.

About an hour later, a gray-white powder continued to fall from the edge of the stone mill, Huo Gang stretched out his hand and touched it, it was very similar to the cement in his impression, but he didn't know what the actual strength was.

When these powders were ground out of two large boxes, Huo Gang asked them to stop for the time being, and there were still unpolished ones next to them, so they were not in a hurry for the time being, so they tested these cements first to see how the strength was.

"Go and bring the prepared river sand, mix it with the cement, and then bring the crushed stone that has been selected over there." Huo Gang directly commanded everyone to start acting.

Although the river flow here in Yangguan is not large, the rivers here in Yangguan have always existed, so the river sand can also be found out, as for the gravel, it is even simpler, next to the Qilian Mountains, there is nothing else, with as many stones.

Everyone acted quickly, and soon something similar to ordinary concrete in his previous life appeared in front of Huo Gang.

"Pour them into this wooden box." Huo Gang pointed to the wooden box next to him.

These craftsmen immediately shoveled all the concrete into a large wooden box prepared in advance with tools, and asked Huo Zheng and them to use two thick logs to stir vigorously in it to make sure that there were no gaps left inside.
