When the farming is not working, if the people want to get extra income, they must rely on their crafts to make money, and the money for digging in the soil is still too little.

But the soldiers in the forbidden army don't have to worry about it.

Because, when they are slack in the farm, they will be called together to carry out military drills, and they will be able to eat and shelter every day, and they will be able to get a lot of money. After Cai Dao became the third envoy, whether it was in the border army or in the forbidden army, all the officers did not dare to drink the blood of the soldiers, falsely reported the quota of the forbidden army, embezzled and took the pitiful low salaries of these forbidden soldiers, and no longer dared to indiscriminately make the forbidden army handle private affairs for themselves.

Did any officer rush to do this in private? Anyway, Cai Dao hasn't found it so far.

Compared with the common people, the soldiers of the forbidden army only need to bear the risk of war, and when the farming is not working, they can get military salaries.

But the people will suffer much more.

In particular, the people living in the north have only one season of grain in their hands, but if they do not have enough fertilizer, they have to fallow the next year, or change to other food crops. According to the latest "Cai's Qi Min Yao Shu", during the rotation of the shift, the farmland that was planted with wheat last year can choose to cultivate two crops - soybeans or alfalfa in the second year.

Both of these cash crops have their drawbacks, such as the low yield of soybeans per acre, and alfalfa cannot be directly used as food to pay land tax.

However, under the vigorous promotion of Cai Dao, the economic value of soybeans has been deeply explored, making the price of soybeans much higher than the price of wheat, which offsets the shortcomings of its insufficient production. Moreover, according to the newly promulgated tax system, soybeans can actually be used as grain to pay land tax directly, and only one liter per mu is levied.

There are many economic values of soybeans, and the most profitable of them is that soybeans can be extracted from oil, and now stir-frying vegetables with soybean oil has become a new trend in the entire food industry in Bianliang City.

After the soybeans are pressed into oil, the remaining bean dregs are also made into soybean cakes, which can be eaten by people and livestock raised at home.

After many experiments and improvements, Cai Dao used this soybean cake to mix other plants or minerals, and made it into excellent feed, which can be used as supplementary nutritional feed for raising cattle and horses, and the effect of the promotion test is very good.

There are also bean skin, bean curd, bean tendon, tofu brain, soybean milk, etc., these various soy products have now become the favorite food in the dinner plate of the people in Bianliang City, its price is much cheaper than meat, but there are many kinds of flowers, a lot of food made of soybeans, when eating, people feel like meat-like texture.

There was not much land distributed to the common people and the soldiers of the forbidden army, but there was a layer of exploitation missing, that is, the exploitation of the landlord class. You must know that the annual rent collected by those landlords is basically five or six percent of the harvest per mu, which is much higher than the land tax levied by the imperial court.

Therefore, whether it is a ding tax or a land tax, there is very little pressure on their survival. In addition, the materialization of the fixed amount of land tax and ding tax has also greatly increased the enthusiasm of the people to invest great energy in improving their own farmland and their desire for advanced planting technology.

After all, whether it is cultivated land or wasteland, as long as the grain and silk cotton produced in their own fields are overproduced, after paying the ding tax and land tax, the rest is their own.

The less land there is, the more people want to learn advanced agricultural techniques.

And "Cai's Qi Min Technique" is compiled by Cai Dao himself, and its content is to record his own experience in planting crops.

It was purchased at the expense of the imperial court and given one copy to each of the local township chiefs and lieutenant chiefs, so that they could pass it on to the local people. In the future, there will be more literate people among the people, and the court will give them free of charge.

The Gyeonggi region has become a pioneer again, and one of the most important responsibilities of the rural literature and rural mathematics stationed in various places is to give the book to every student and to those farmers who want to learn it.

Moreover, when Cai Dao harvests every autumn, he will also send people to various places to ask the local planting masters, although most of them are honest farmers who don't know a big word, but after all, they have been farming for most of their lives, and some aspects of experience are still richer than Cai Dao.

In addition to the tax and the land tax, there are two very important elements in the tax system - military service and conscription.

In the history of China, what the people really hated was not the excessive taxes and miscellaneous taxes, but the endless military service or conscription.

Look at the kings of the fallen countries before the Great Song Dynasty and the dynasties that collapsed, the reason for their demise was to use too much people's power, coupled with natural disasters.

The most criticized thing about the Great Song Dynasty is the forced labor, often those who should be forced to serve the common people will be ruined because of this, which is also the only one in Wang Anshi's new law that can be continued, and when Sima Guang forcibly abolished it, it was also opposed by some officials within the conservative faction.

It is precisely because the conscription system is too civilian.

Sima Guang always said that the ancestral rites and ancient methods were learned, but he didn't mention it, and in the Han Dynasty, there was already a change of endowment.

Anyone who is unwilling or unable to serve in person can pay a sum of money to hire someone to serve in his place, or the government does not need his personal service and order him to pay for the service.

In fact, this is the Han version of the exemption law.

Conscription, the unpaid labor that the ancient Chinese rulers forced civilians to perform, including forced labor, miscellaneous labor, military service, etc.

The key lies in the word gratuitous, if it is paid, even if it is forced, the people can still survive.

Of course, with the formation of the conscription system, military service is no longer unpaid.

Then, only forced labor and miscellaneous labor remain.

All local governments will build water conservancy, build bridges and pave roads, and recruit people for free.

Han Feizi Bei Neizhong, there is such a paragraph, if there is less servitude, the people will be safe, and if the people are safe, there will be no power, and if there is no power, the power will be destroyed, and if the power is destroyed, the virtue will be on top.

The general meaning is that if there is less conscription, the people will naturally be stable, and when the people are stable, the rulers will not need to give too much real power to the local officials, and the real power in their hands will be weakened, then they will not be able to form an overly powerful local family or a warlord who divides the locality, and the people will remember that this is the emperor's kindness.

In order to prevent the local officials from endlessly serving the people without private service and making the people want to be forced into service, Cai Dao gave the emperor a lesson.
