Li Yan casually threw the water balloon into the spring water of the space, anyway, the water is not poisonous, the water quality is not bad, let him return to the source.

Then Li Yan turned his gaze to the pile of black soil that had not yet been treated, and the pile of black soil was not very much, a pile half a meter high.

Now Li Yan already knew that he could use space soil and space water to transform this black soil, but he was not in a hurry to transform it, he wanted to conduct an experiment and find out the best transformation plan.

After looking at the pile of black soil for a while, Li Yan said in a deep voice: "Shovel, divide him into ten equal parts." ”

Li Yan's order had just been issued, and before the shovel could make any move, the black soil on the ground was automatically divided into ten equal parts, Li Yan couldn't help but be happy when he saw this situation, it seemed that as long as it entered this space, it could act according to his own will, which was really good.

Thinking of this, Li Yan decided to test it, and he said in a deep voice: "Space, calculate the optimal ratio of space soil and space water used when improving black soil. ”

"Permission exceeded, can't be calculated!"

"Holy! It's better to do it yourself. Li Yan couldn't help but curse secretly, filled the bucket by the spring with spring water, and picked up a small shovel to shovel a spade of space soil.

The reason why Li Yan wanted to calculate this ratio was because he was afraid that if he used too much space soil, there would be less soil in the space, and in that case, it would really be worth the loss.

Now space is Li Yan's biggest reliance, if the space is destroyed here, then all his plans will be in vain, there is no way to realize it, and he will return to the situation of being poor and white, guarding this dead land and waiting for death.

Out of this consideration, Li Yan wants to calculate the optimal ratio of space soil and space water needed to transform black soil, which can not only better improve the black soil, but also make space soil and space water not use too much.

Although the basic setting of the game played by Li Yan is the same here, this place has become Li Yan's last reliance, so he can't be as casual as playing a game, and he has to do a good job of calculating every step.

Li Yan first sprinkled the space water on the black soil, and then watched the changes in the black soil with great attention, while carefully calculating the ratio of the two.

When the space water is poured on the black soil, it is like the fairy dew in the willow branch bottle of Guanyin, and the black soil immediately changes, and the black soil like oil sand recedes little by little The oil-like black color has become a unique color of the black soil, and the sand-like things in the same place are also slowly disappearing and becoming ordinary soil.

After the small pile of black soil was completely improved, Li Yan carefully calculated that it was almost fifteen to one, that is, with one-fifteenth of the water, a pile of black soil could be transformed.

Li Yan is still very satisfied with this result, which means that the improvement ability of space water to improve black soil is still very strong.

Then Li Yan sprinkled the space soil on another pile of black soil, this time the changes in the black soil were a little different from when using space water, the black soil transformed by space soil looked more fertile than the black soil transformed by space water, but the ratio of space soil to black soil used was ten to one.

Li Yan turned like the third pile of soil again, this time he used space water and space soil to improve the black soil in a ratio of nine to one, and the result was successful, but the improved black soil was no different from the black soil improved with space water.

Then the eighty-two ratio, the result is still the same, the seven-three ratio, the result is still the same, the four-six ratio, the black soil becomes as fertile as the black soil improved with space soil, and then it looks no different from the six-four ratio.

By now, Li Yan no longer needs to be experimenting, and the use of space water and space soil in accordance with the ratio of June Fourth should be the most reasonable for the improvement effect of black soil, which will not cause too much waste, and the improved black soil is the best.

With the results of such an experiment, Li Yan was already very satisfied, he put the bucket back in its place, put the soil back on the ground, and then left the space.

Returning to his room, Li Yan sat there quietly, sorted out the harvest of this space trip, the land has been upgraded, the land can be opened, and the best formula ratio for improving the black soil has been found, then he should start preparing now and start improving the black soil, it is already April, if you don't do it at this time, it will be past the agricultural time.

Although Li Yan does not distinguish between grains and grains, he still understands these basic common sense, planting in spring and harvesting in autumn, and now is the time when spring has just begun, and it should be the time to plant.

And now there are 200 gold coins in his space, six bags of forage seeds, two bags of cabbage seeds, two bags of corn seeds, two bags of wheat seeds, and there is still a season of 80,000 catties of radishes in the warehouse.

Fortunately, all the seeds can be used in the space, which means that as long as he improves the land outside, then he can plant the seeds produced in the space outside.

While thinking about this, Li Yan walked out, he wanted to measure the land as soon as possible, so that he could carry out land improvement.

As soon as he went out, he saw Tie Dan and Dog Dan standing in front of the door to show him, and it seemed that no one was looking for him.

Li Yan nodded to the two of them and said, "Tie Dan, go find a bundle of rope and a ruler, and let's measure the land." Although Tie Dan didn't know why Li Yan did this, he still answered and immediately went to find it.

Because the place they are coming to is the Loess Plateau, where there is nothing, in order to cope with this situation, Zhao Lin has prepared almost all the things needed for life, the most of which is food, seeds, all kinds of daily necessities, things like ropes and rulers, and naturally prepared a lot.

Tie Dan didn't rush to find something, but turned to Li Yan and said, "Young master, it's almost time for lunch now, Grandma Li Na has come back to prepare lunch for you, let's wait for lunch and go after lunch." ”

Li Yan was stunned for a moment, looked at the sky, and sure enough, it was already noon, and he also felt a little hungry when Tie Dan said this, so he nodded and said, "Okay, then wait until lunch." With that, he led the two of them to the castle's restaurant.

As soon as the three of them arrived at the restaurant, they saw Li Na and Zhao Xuan setting up tableware there, Li Na saw Li Yan coming, and hurriedly bowed to Li Yan and said, "Young Master, you are up, I am about to ask Zhao Xuan to call you to dinner." ”

Li Yan smiled and said: "Get up, Grandma Li Na, in the afternoon, don't let those slaves clean the cave, wait for tomorrow to clean it, anyway, the blue-eyed rabbit can't be transported now, in the afternoon, you prepare a ruler and rope, go and measure the black soil outside, one piece per ten acres, make a mark, now it's about to spring ploughing, right?" We need to hurry. ”

When Li Na heard Li Yan say this, she said with an ugly face: "Young master, the black soil outside can't be cultivated at all, although we bought a lot of seeds, but those seeds are all used to plant in the mountains, and planting them in the black soil is all wasteful, and it is useless to measure them." ”

Li Yan smiled and said: "Don't worry, Grandma Li Na, I have a way to improve the black soil outside, and I can make those black soil fertile soil that can be cultivated, you just need to be responsible for measuring the land." ”

Li Na's eyes lit up and said, "Young Master, what you said is true?" Do you really have a way to improve the land out there? What land can be made arritable? Her voice trembled a little, she was so excited.

The area of the Loess Plateau is the largest plain area in the entire Maise Empire, and it is one-third the size of the total area of the Maise Empire, but it has not been counted in the land area of the Empire by the Maise Empire, because it is a dead land.

But if this place can be cultivated, and those black soil can grow crops, what will become of this place?

It would become one of the richest and most coveted places in the entire Wheat Empire.

Although the Tian Yuan Continent is a magical civilization here, people pay more attention to things like magic, martial arts, and magic crystal ore. But no matter what time and plane, it is an indisputable fact that agriculture is the foundation of a country.

The people live on food, and your magic is strong, and you can't eat it! Your martial arts skills are high, and you have to eat!

Even if a country has money, it is impossible not to grow it at all, and there is no country that will completely hand over food, which is related to the livelihood of the people, to other countries, if that is the case, then the country is not far from extinction.

If all the land here on the Loess Plateau can be cultivated, then there is no doubt that this place will become the granary of the entire continent, and there is no place on the mainland that is as flat and easy to cultivate as the Loess Plateau.

And the most important reason, which is also Li Na's excitement, is that in order to completely let the Kalin family have no chance to turn over, His Majesty Zhang Tie, under the witness of the temple envoys and envoys from other countries, reached an agreement with the Kalin family, and under the witness of God, the Loess Plateau will become the permanent fief of the Kalin family.

Don't underestimate this agreement, because this agreement has the testimony of the envoys of various countries and has been recognized by the temple, then it has been testified by God, and anyone who dares to violate this agreement is disrespectful to God, and will be attacked by all forces on the continent and punished by God.

And this agreement has another feature, because of the testimony of the envoys of various countries, even if the Maise Empire is destroyed in the future, other countries rule this land, and the Loess Plateau is still owned by the Kalin family, and no empire has the right to take it back, including the temple.

Think about it, what will it look like when Li Yan completely improves this land? Li Yan got the largest fief on the Tian Yuan Continent, and it was the kind that existed permanently, and no one had the right to take it back!

How could Li Na not be excited? If Li Yan really improved the land, then the Kalin family would become the richest and most powerful family on the Tian Yuan Continent.
