That's right, the compressed biscuits came from Ding Yun.

But she didn't sell it herself.

She wholesaled it to others.

There are three main reasons, one is that the cornucopia hidden space has been filled with compressed biscuits, and at the same time, Ding Yun has other things that he wants to copy and must be vacated.

The second is that those compressed biscuits were bought and put in by Ding Yun four years ago, and they are copied, that is, they are exactly the same, the production date, the expiration date and so on are also the same.

Although time stands still in the hidden space, and things can't be broken for ten years and a hundred years, others don't know that the production date on it is more than four years ago.

There is less than half a year left to expire.

Whether it's artificially erasing the production date, re-marking a new date, or waiting for the expiration date to sell it before it expires, it's quite troublesome, so it's better to clear it before it expires.

And because the production date of this batch of compressed biscuits was produced before the National Food Industry Integration Reform was made by the Food Administration, there was no need for food stamps to buy these compressed biscuits at that time, or the food stamp system had not yet been introduced at that time, so it is easy to explain.

Third, of course, Ding Yun is short of money.

Although the state has increased support for agricultural research, most of this part of the support subsidies are given to famous researchers.

Agricultural research is not mathematical physics, even if there is no large number of experimental equipment and experimental processes, you can do theoretical research and publish sensational theoretical papers in the world.

Agricultural research is a practical class.

There must be experiments to achieve results, and every paper must basically have a realistic basis and be supported by data.

Although Ding Yun has worked hard in the past three years, she is obviously not qualified enough, and she can only follow her mentor to do chores by applying for experimental projects in the experimental field independently.

If there is nothing wrong with the world environment, then Ding Yun is naturally not in a hurry, and he will do it slowly, it doesn't matter, but the current world environment and food reserves obviously can't last long.

If there is no result, the country will be in chaos.

After all, the troubled times of all dynasties have originated from famine.

Therefore, Ding Yun naturally has to put aside his mentor to do independent research and get some results out as soon as possible, which can not only save the world, but also gain a lot of influence by the way.

And all this requires money.

If she doesn't sell those compressed biscuits, she has nothing else to sell, so she can't sell the cornucopia.

As for the source of compressed biscuits, she also basically made it up, saying that she won the lottery that year, and used the winning money to speculate in stocks for a period of time, and then worried about the end of the world, so she specially hoarded so many compressed biscuits.

Although it's almost the end of the world.

But the cookies were about to expire, so I thought about emptying them.

As for the winning records, stock trading records, purchase records, and even a series of records such as the production records and sales records of compressed biscuit manufacturers, Ding Yun has himself modified, compiled, and added them online, even if some people suspect it, in-depth investigation, it is seamless.

And she doesn't take food stamps to sell, so it's even more fine.

Because it has never been said above that merchants must collect food stamps when selling food, but merchants must use food stamps when buying raw materials, and ordinary merchants do not collect food stamps to buy raw materials without food stamps.

But Ding Yun didn't plan to continue to produce and sell.

She doesn't charge food stamps and sells them at a high price, and no one can put a beak.

In addition, there are a lot of compressed biscuits of millions of cubic meters compared to individuals, but they are really not much compared to the whole country, and there are still people who stock up on a large number of goods, save them, and are not willing to sell them outside.

The actual outflow is less than one-tenth.

So in the end, it did not cause any twists and turns, and at the same time, it had no impact on the consumption of food in the whole country.

Because most of the people who bought it back saved up and didn't eat, and kept it at the bottom of the box, in case the number of food stamps continued to be reduced in a few years, or it was difficult to distribute food, then these biscuits could save their lives.

……

Speaking of Ding Yun, after she vacated the cornucopia space, she began to copy agricultural research, some essential substances needed for the cultivation of improved seeds, and those that were not easy to buy.

And spent money to set up private research institutes.

Part of the land was leased to serve as a test plot.

She has a lot of grain seeds in her hands, and there are also those that can be extremely cold-tolerant and extremely drought-tolerant and high-temperature, but those seeds are all spiritual seeds, once planted in large quantities, it is very likely to quickly lead to the revival of the aura, and now the environment is so bad, the survival of human beings is quite difficult, and then a sudden revival of the aura is really I don't know how many people will die.

Therefore, there is only one thing that Ding Yun has to do now, that is, to use the existing spiritual rice seeds to cultivate cold-tolerant and drought-tolerant, high-temperature and low-temperature tolerant, and without spiritual energy.

It takes time.

After all, Ding Yun now had neither the ability to accelerate time, nor the golden finger to use such as seed cultivation space, so he could only let the hybridization of those spiritual rice seeds degenerate from generation to generation, reducing the aura contained in them.

In addition, she had to try to make sure that the output did not drop too low, which undoubtedly made it even more difficult.

However, in any case, compared to other breeding institutions that are still trying their luck and being more patient, at least Ding Yun already has a specific research direction, and he only needs to spend a little more time in the future, and he is already much ahead.

However, it didn't take long for the environment to change again.

One is the sudden eruption of the world's largest volcano, and the second is the threefold increase in solar activity in half a month.

Theoretically, volcanic dust and other products created by volcanic eruptions block sunlight and lower temperatures, which in turn increases in temperature.

The two will offset better.

But in reality, these two things cannot be offset.

It's not a matter of pouring water and adding water.

As a result of these two events, a dozen countries in the volcanic eruption region have seen mass plant deaths, environmental degradation, and air deterioration that have barely survived, while those countries that are in the middle of summer have experienced severe drought due to increased solar activity.

With a drought that is rare in a thousand years, rivers have dried up, most of the communication facilities have been damaged, and power plants have been paralyzed, and everything seems to have returned to the great drought of hundreds of years ago.

At the same time, peat in the Antarctic and Antarctic burned at low temperatures in a large area.

The ice is decreasing every day at a rate that is visible to the naked eye.

The news no longer reports on these things, because reporting is useless, it has no other effect than to increase panic, and the state is forced to make a new choice, which is to officially launch the doomsday survival mode.

For example, the gathering of population, migration and convergence to core water sources, the large-scale construction of seawater purification industry, the suspension of all industry development unrelated to survival, the concentration of national forces, the construction of underground survival bases and other projects.

Another example is to reduce the skew of funding for agronomy research.

No way, now the environment is changing day by day, even if today it is researched that crops can grow normally in an environment of minus 40 degrees, and the temperature rises to minus 43 degrees in a few days, it is useless.

In addition, natural disasters are frequent, and there have been more than one occurrence in various places, and natural disasters have occurred before the crops are about to be harvested.

The event that all the crops were completely destroyed.

Therefore, the General Food Administration can only change its policy, no longer demanding that food must be used to feed people, but start to research food substitute processing, hydroponics, underground cultivation, and even artificial starch, and hope to produce science fiction nutrients in the shortest possible time.

There is no way, the bottom line is broken step by step.

In the absence of any other hope.

Not dying of starvation is already the best outcome.
