The lost money is enough for Datang to repair how many official roads, how many rivers to repair, and how many things to solve? It can be said that ...... This is an unsolvable problem, and it is not impossible to solve it, that is, they opened the pit as soon as possible in the black soil in the northeast.

The black soil in the northeast has been detected by them, including the climate around the black soil, when to plant and harvest every year has been tested by professional agricultural personnel, Huo Gang did not lie to them, the land here is too fertile, enough for them to grow enough grain.

Therefore, when the land here is reclaimed, it can naturally make up for the shortage of grain in Datang.

In fact, even so, Datang's food is not enough, which Li Tai knows, his two elder brothers and his father are naturally also clear, and those ministers of Datang are also clear. Because Datang's food consumption is growing rapidly every year, these food consumption is not only a problem of population growth for the people of Datang.

It also includes the problem of the growth of food consumption of the people themselves.

The reason is very simple, what did the people of the Tang Dynasty eat in the past? I can't eat enough whole grains! Survival is the first priority, when they used to eat noodles, such as bran was almost mixed into white noodles for use, although it was coarse grain black steamed buns, but at least they had a full stomach.

The point of the problem is that such a black-faced steamed bun with bran skin was not enough for the people of Datang before! It is conceivable that there is a food shortage in Datang.

And now? Not only can everyone eat enough for ordinary people, but the most important point is that the vast majority of people no longer eat coarse grains, they have begun to eat fine grains, and the bran has been ground separately to feed pigs, chickens and other poultry and livestock, and increase meat for the people's homes.

From these alone, it can be seen that the living standards of the people in Datang have been continuously improving, and this alone will increase food consumption by one-third. With the increase of fine grains, those that were not too delicious in the past, and the planting area of sorghum, corn and so on is naturally decreasing.

Also, when people's lives are better, there will naturally be more normal pursuits, such as wine. Brewing wine requires a lot of food, and it is almost impossible for ordinary people to drink Datang wine in the past, or once or twice in a lifetime.

But when alcohol gradually began to spread into the lives of ordinary people, the amount of alcohol needed was a behemoth, and the same amount of food consumed was naturally a huge number.

In addition, there is the invention of stir-frying, which was gradually introduced into the Tang Dynasty by the Han Dynasty and has swept the entire Datang folk, because of the improvement of life, many people also need to stir-fry, and oil extraction needs to use beans and other beans, or rapeseed and other specially planted oilseeds, which are also land that needs to be cultivated, or consume food.

In this way, the grain grown on the cultivated land of Datang is decreasing, even if the grain grown by Datang is not reduced, according to the current consumption method, the food gap of Datang is as high as half or more!

In fact, at present, two-thirds of Datang's grain needs to be imported from Dahan.

Of course, there is also a reason for this because Datang is storing grain, and Datang naturally sees some certain threats, not that they think Dahan will do it on purpose, but they are also afraid of accidents, so they also store some grain, but the grain they have in stock is basically only enough to eat for a year.

It is difficult to save more, the storage conditions, and the speed of Dahan's imports are actually limitations.

But being able to save for a year is already good, how could Datang dare to say that there is food for the population of the whole country to eat for a year? Don't even think about it, it's impossible.

Now it is a good thing, and when the black soil in the northeast begins to be cultivated, this pressure will be even more relieved.

It's just that the black soil in the Northeast is very slow because of population and other restrictions, but this time there is good news, that is, the railway technology has been opened, allowing Datang to build all the way from Chang'an to the Northeast, although the railway may go far in twists and turns, but as long as it is built in the past, the control of the Northeast will naturally be improved to a level.

The speed of immigration can naturally continue to accelerate, it is too far away, and the current speed of immigration in Datang is certainly impossible to keep up.

It is also because of these reasons that Li Tai and the others have learned a lot, and these methods are actually summed up by Li Shimin, and Li Tai and Li Chengqian have also seen them, because they know the same methods, and they can use them for other countries!

Because Datang also has such an advantage over other countries!

As for the grain, of course, it is not a problem, just continue to buy from Dahan, anyway, his master said, you can have as much as you want, and the transport ships from the upper reaches of the Yangtze River to the lower reaches have also been updated and larger, and the speed of transportation is naturally faster.

So in fact, the grain from the Tang Dynasty is transported to the Wa Kingdom, in fact, the price is not high, if it is sold according to the grain price of the Wa State, their profit is not small, but Li Tai has also learned, so he will not sell according to the grain price of the Wa State.

Just like the method used by his teacher, he also has to control the grain of the Wa Kingdom, of course, whether his teacher did it on purpose or not, then no one knows, but now it has formed an established fact, whether Datang wants it or not, the food is in the hands of Dahan.

For example...... Can the Japanese people raise a large number of silkworms? They buy silk from their hands and sell it to them at a low price to make silk silk and attack their local textile and silk markets. Or let them use a lot of land to grow eucommia, and grow hemp.

Although linen clothes have been eliminated, the consumption of linen has not decreased at all, a large number of sacks, as well as the manufacture of the sea fleet, etc., Datang has to consume a large amount of linen every day.

Whether it is a burlap bag or a fine burlap bag, there are different uses, and the demand for burlap is greater than before.

The Han Dynasty did not produce linen on a large scale, so many textile merchants in Datang used it to produce linen except for high-end silk.

explained to Langchuan Hakata, Li Tai didn't care about these things, he only needed to do a few things every day, watching the construction team outside the city get bigger and bigger, and the same food expenditure was naturally more and more, but he didn't care about this food at all.

The entire Donglin Island is only 400,000 people, and at the current rate, and the grain he transported, Li Tai can sustain it for a year! As for the follow-up, it's not that there is no food, but that there is no need, and the food needed by 400,000 people can be transported by Datang's naval fleet now.

Of course, they didn't ship that much, after all, they can still produce and grow locally.

Therefore, Li Tai does not have to worry about the lack of food at all now, because it is impossible for 400,000 people to work for him, and it is impossible for him to feed everyone. After he has established his authority, he will later distribute land to everyone.

Moreover, Li Tai was also ready to carry his teacher's set, that is, the food stamps.

It doesn't matter if you don't do it yourself, it's always okay to just copy it, right? What's more, his teacher has already given him a perfect solution to this example, as for the reason why the food stamps will not be imitated, to be honest...... Let's not talk about whether the people here dare or not, even if they do, they can't even make paper, fake a fart!

He bought this special paper directly from Dahan.

So Li Tai is naturally not worried at all.

Huo Gang naturally knew about these things that Li Tai did, but he naturally didn't care, the special paper sold to Li Tai was the first generation of banknote paper belonging to the Han Dynasty, and the Han Yuan of the Han Dynasty had been updated to the third generation of paper.

The first generation of paper Datang can't be made, and it's even more impossible for the Wa Kingdom.

Of course, in terms of printing, movable type printing Datang has mastered it, Huo Gang doesn't care anymore, Dahan's printing technology has already broken through movable type printing, and he doesn't care about Datang's backward printing system.

So Li Tai wanted to buy paper, Huo Gang naturally gave it to him, and he gave him the cut paper directly. He still believes in this child's ability to copy, to be honest, Huo Gang also wants to see what Li Tai can do, but it shouldn't be difficult.

The main reason is that the system of the Japanese state is too backward, and if someone really starts to liberate it, the government of the Japanese state will not be able to bear it at all.

In fact, just as Huo Gang thought, seven days after the start of Bodu City, the other nine counties on the east island also started similar work, employing local people to work with grain, but the other nine counties were relatively small, and the population of these nine counties was not much anyway.

So this kind of small scale is enough, to build barracks houses, and when the barracks houses are completed, they will start leveling the roads in various counties, and even start building toilets and other related facilities, in short, these works will take a month or two.

You don't need to send money at all, just send food.

Li Tai didn't care about this food at all, and he paid for it completely, but this process made Li Tai's fame resound throughout Donglin Island, and he soon established great prestige on Donglin Island.

In this process, one by one the yamen referring to the Tang Dynasty began to be established in various counties, and the scholars assigned to each county gradually began to cooperate with the local aristocracy.

Li Tai was waiting for Langchuan Hakata to find the chicken for him, Li Tai was not in a hurry at this time, but what Li Tai didn't expect was that this time didn't make him wait too long, only about a month after he started to work on infrastructure construction, the drum of the Dali Temple Yamen established by Li Tai was finally beaten.

Li Tai, who learned the news, immediately couldn't help it, and directly ordered people to investigate and arrest him.
