It is not possible for one person to continue to protect, because a person's lifespan is limited and his energy is limited, and it is too difficult for a person to continue to protect, and it is a thousand-year-old guard.

These old people sent to guard, generally speaking, Fan Jingjing will find a way to tell them the purpose of guarding, because it is not to let them understand, but to let them pass on this concept to their children and grandchildren.

Otherwise, it will be difficult to implement this concept if no one communicates it and gets it to be accepted by future generations.

It is not only in these guardian villages that it is being promoted, but also in the Fan Family Manor.

It is very difficult to protect, but it is only a matter of a moment to destroy, not to mention some plants, if the outside world begins to decrease, the value of plants will begin to increase, when the value begins to increase, people begin to use these valuable plants and animals to make money, it is easy to be dazzled by money.

You must know that most people can't avoid the temptation of money, because people are resistant to money, that is because they don't need money much in life, because the money on his body has been satisfied, and the excess depends on whether he is greedy or not, whether he wants to do it, whether he has any goals to do, and whether he needs money to complete it.

If he just wants to meet his needs for food, accommodation and entertainment, a certain amount of money is actually enough, even if he is ready to lie down and have a good time, including medical treatment, there is enough money of 100 million yuan, and most of the people who want to continue to make money with 100 million yuan have some other reasons, some people are because there are many people in his business, and he constantly has to let the enterprise continue to maintain to ensure the living needs of others.

Otherwise, he can sell this enterprise and live a free life with money, but all the money, in fact, does not necessarily maintain its value, if there is a problem in the country, the money will no longer have value, and it is even likely to be inflationary, only money, people without industry, often very miserable, and there is industry and agriculture as the basis.

However, most of the farmland will be very restricted if you want to occupy it, but no matter how limited it is, it can still be produced, and the basic value of the land can be maintained through these lands, and it is impossible to devalue the land in the case of an increasing population.

But there is a lot of land in Datang, and more wasteland exists, which will really depreciate completely.

Because when a piece of land is completely abandoned and cannot be used, it will lose its value, it may be polluted, it may be other reasons, so that the land cannot continue to exist, in this case. The person who buys the land can also buy several scattered plots of land, in different countries, unless there is a world war, or the land will not depreciate at the same time.

But even in the event of a world war, once the value of the land that has entered into peace rises again, no matter how much the population decreases, there will be a great demand for land.

The location of the city will shift, but the possibility of depreciation of rural land is still very low, because you are not buying urban land in the first place.

The value of the land in the city is a bit inflated because the people are no longer in this place, and the value of the land is not in this place at the same time.

Therefore, some places have been speculated very high in value, and people have left one after another, and they have lost their original value, unless people continue to push the land of the city, or the city will be in a precarious stage if it wants to maintain, and it may collapse at any time.

So it's a lot like the bubble economy of the island country, when there was no way to do anything, and when the very high rent was maintained, the value of the place would begin to collapse.

Even the price of real estate has been cut in half.

What's more, Fan Jingjing will study these native plants and even plants that have disappeared in later generations, and do the work of variety improvement, Fan Jingjing is a student of the Department of Agriculture, and the students of the Department of Agriculture have a job to do agricultural variety improvement.

The improvement of agricultural varieties is sometimes done by grafting or various methods.

Some are made with fertilizer, some are genetically improved, and some are genetically improved, and Fan Jingjing certainly doesn't want to do it.

In fact, future generations will not be able to confirm that genetically modified crops are really good and will not cause physical damage.

The food is still natural and more acceptable to people.

At least in the era of science and technology, what can not be done, but many can be done at this time, because many plants have not yet become extinct, Fan Jingjing can find a lot of fruit trees or trees that can not be seen in later generations in the mountainous area of the Qinling Mountains, she asks people to study the characteristics of these fruit trees, and will come together to find a way to graft and improve, in addition to the method of grafting and improvement, but also choose particularly ripe and delicious fruits and then cultivate, in each cultivation, choose the best fruit, It is possible to choose a better breed from them.

Because in fact, gene mutation is actually a normal behavior in every species, this is a way to continue the survival of the species, only by making the gene mutated to be more suitable for the survival of this world, can the survival chance of the race be maintained, maybe in the future life, the original bitter fruit becomes a sweet fruit.

Fan Jingjing feels the happiness of agriculture in this era, but in this era, I want to engage in work that can be done, but it is so hard and so tiring, fortunately, most of the heavier work, people will not let Fan Jingjing do it by themselves, and the people who assign the work will hand over these tasks to others to do, and the farmland of Fan's manor is a scientific and efficient farmland.

They all think that it is good for the owner to do some light work, and even standing in the countryside to guide them can also bring them greater progress, and there is no need to carry the harvested grain with a hoe and follow everyone to dry the rice and turn the ground.

Every time the Fan family manor gets a bumper harvest, it can make people smile, even if such a harvest can be done every day, even if they no longer pay attention to the harvest of cereals, they also attach great importance to the harvest of every kind of vegetables and fruits, and even they also plant grasses specially for cattle and sheep to eat, so that cattle and sheep can eat fat and strong, and finally enhance their own meat.

Fan Jingjing said that if people eat more meat, the demand for food will decrease, because meat is actually very anti-hunger.

Once you eat a piece of meat, you actually have less need for food.

As for growing pasture, the grass that these cattle and sheep need does not need too good land, and even does not conflict with their crops, resulting in more land they can use.
