It's night.

Cao Ang looked at the solid plank under his feet.

Looking at the calm river with no edge in sight, the whole heart is full of comfort.

I couldn't help but stretch my waist.

Since hitting Diao Chan and the Queen Mother, the number of times it takes to get on the ship has increased, and Cao Ang has not counted it carefully.

But I didn't expect to return home this time, and I was unexpectedly happy to unlock a chance to board the ship.

It can be regarded as a rather gratifying thing, after all, Dong Bai's serious illness is almost cured, and he can fish out another item from the river on his side, no matter how you think about it, it is a big profit.

And Cao Ang pondered slightly.

I think that the cooling-off period between Diao Chan and the Queen Mother should be about the same, just the difference between the days before and after.

Case.

In the next few days, I will run to the Queen Mother a few more times, and maybe I will be able to board the ship again.

After thinking about it for a while.

Cao Ang secretly wrote down this in his heart.

Then he walked to the side of the boat, and without any hesitation, threw out the golden fishing rod in his hand.

Drift into the river with the fishing line.

I waited less than half a cup of tea.

There was a ripple on the surface of the river, and the fishing line that went straight into the water began to shake.

I waited a few breaths.

As Cao Ang pulled up the fishing rod, a boxy brocade box was pulled to the deck.

……

Stick the rod to the side of the boat.

Cao Ang couldn't wait to open the brocade box.

What catches your eye is a two-roll thread-bound book, which is quite well-made from the exterior cover, and the texture of the paper is quite good when touched by hand.

It's just strange to Cao Ang.

The covers of these two thread-bound books were empty, and even when the pages were opened, they were also blank, and not a word could be found.

Well?

Cao Ang was a little confused.

Could this be that it is caught and there is no word in the sky?

According to various routines, this kind of wordless heavenly book is generally roasted with fire, or sprinkled with water, which is a method that normal people can't think of in order to make its handwriting visible.

But Cao Ang felt that the things that came out of this river should not be so cerebral palsy.

This made him unable to help but take out the book, and then rummaged through the brocade box again.

Then I pulled out a large stack of notes.

This time there are words.

Each note is a noun that reads a series of food crops such as millet, millet, wheat, and rice.

Counting them, there are dozens of them.

These things are supposed to have something to do with the thread-bound books themselves, but I don't know exactly what the situation is.

After pondering for a moment.

Cao Ang didn't dare to act at will, so he chose to put things back in place as they were, and then walked quickly to the stone tablet.

Carefully interpret the inscription on the stele.

……

"Item Name: Self-selection book of improved methods for excellent breeding and selection of grain crops.

Function: Each volume of the book corresponds to a food crop, after choosing the desired food crop, the content of the corresponding crop will be displayed in the middle of the wordless book.

Remarks: Those who select and breed, make good use of the method of improvement and live countless people, can be called a great sage! ”

This is the first time Cao Ang has seen an item with such a long name, and it is also the first time he has encountered a treasure that gives him the right to choose.

Among the dozens of major food crops, choose two and stick them on the corresponding books, and the two books will be presented in the corresponding places.

How does it feel a bit like an item selection box?

It's too advanced!

But after sighing.

Cao Ang began to think seriously.

Being able to give himself the right to choose independently, rather than just forcibly giving him a preferred breeding method for food crops, is already quite preferential.

Then all he has to do is make good use of it.

Such a great opportunity cannot be wasted.

Choosing one at random, and not using it at all right now, is a huge waste of this hard-won opportunity.

Cao Ang walked briskly back to the box.

Then he flipped through the stack of notes.

Begin to pick and choose.

……

The following principles are generally followed.

One is to belong to the mainstream crops of the current era, only the heavier the proportion of the agricultural structure of the Han Dynasty, then it will be more cost-effective to optimize and improve the cultivation of improved varieties.

The second is that in this era, the crops that the Central Plains have, such as corn, sweet potatoes and other food crops, even if you know that this thing has a high yield, it can bring a lot of food.

Cao Ang will not choose either.

Because there is no one in the territory of the Han Dynasty at the moment.

When he finds the seeds of corn and sweet potatoes and cultivates them, then the people in the world probably don't know how much they have starved to death.

No matter how good the future is, if it is not needed at the moment, and cannot be quickly transformed into a resource, then its priority can only be ranked at the bottom.

The last requirement is to improve the difficulty of cultivation, which is also within the scope of consideration.

Although the stack of notes does not say who is easy or harder, the steps are not revealed before the selection.

However, Cao Ang himself has a basic logical judgment, and he can only rule out food crops that may take a long time and even consume a lot of manpower and material resources to carry out experiments to improve little by little.

It is always impossible to choose a high-yielding crop.

As a result, it took several generations to cultivate and improve, and maybe a generation of monarchs and ministers is gone, and this thing has not been changed.

What's the point?

Combine the above principles.

Cao Ang finally made his choice.

……

Looking at the few notes in front of him.

Cao Ang first removed millet and soybean, two food crops that have gradually withdrawn from the stage of the times, and account for a small proportion of the main grain production at present.

Secondly, after a struggle of ideas.

And he took out the rice.

It must be admitted that when he saw the rice, Cao Ang was very moved.

The reputation of this thing is too great!

But after rational thinking, Cao Ang could only choose to give up.

At present, the center of gravity of the whole country is in the north, and the center of gravity of politics, economy, culture, and even population is all in the north.

Compared with the north, the south is in a state of absolute imbalance, and rice, a crop, although it can also be grown in the north, is far less effective than the south.

In the north, the Liaodong region, which can grow rice on a large scale, is currently in the hands of Gongsun Kang, and most of it belongs to foreign areas.

Then if you choose rice blindly.

As a result, after the improvement is developed, it will not have much effect.

That's blindness.

Perhaps, in the future, after the unification of the whole country, Cao Ang will gradually develop the vast areas of the south and raise the level of development of the south.

But that's a long process.

It doesn't happen overnight.

And when the whole country is unified, it can continue to expand southward, where there are some high-yielding rice varieties in itself, so there is no need to waste the opportunity now.

Thus after several exclusions.

Cao Ang had two notes left in front of him.

"Millet" and "Wheat"

This is Cao Ang's choice.

The former is the largest proportion of grain crops in the Han Dynasty at present, and it has a pivotal position in the proportion of grain output in this era.

And wheat is not as important as millet.

But it has also come to the fore.

At the same time, wheat is mainly produced in the north, and it is a crop that can be developed and bred in the shortest time, and then come in handy as soon as possible to increase grain production.

These two are basically the optimal solution after the synthesis of various items, so Cao Ang did not hesitate to paste two notes on the two blank thread-bound books.

……

"Whew!"

As Cao Ang made his choice.

The words began to appear on the two volumes, while the rest of the unselected notes instantly ignited and quickly turned to ashes.

A moment later.

Two books full of words appeared in Cao Ang's hands, and the thickness of the books was even slightly different because of the different varieties.

After getting the finished product.

Cao Ang couldn't wait to open the book.

The inside is densely packed with words, for Cao Ang, who doesn't know much about agriculture, and can even be said to know nothing except for some corner news.

These two things are basically equivalent to the Book of Heaven.

Unless he can calm down, immerse himself in the book, read through it slowly, and study it with the real thing.

Otherwise, it will definitely not be able to eat through.

But at least he could understand the words.

There are some very conspicuous, title-type texts, and Cao Ang can still understand the meaning.

Roughly flipped over.

The book contains how to choose the grain species, how to breed it, and what kind of conditions and operations need to be carried out in order to achieve a greater probability of success.

These are the contents of the book.

And take wheat, for example.

The book also lists the directions for the cultivation of wheat.

Including high yield, strong adaptability, resistance to diseases and insects, lodging resistance, temperature and cold resistance and other aspects.

……

"Shhh...... Call! ”

Closing the book, Cao Ang closed his eyes and leaned against the side of the boat.

The whole person couldn't help it, took several deep breaths one after another, only to feel emotional, and his heart was inexplicably gone.

Good stuff, it's definitely good stuff!

After advancing, the surface of the river became extraordinary, and such a precious thing could be obtained from it.

But anything that has to do with food.

In the era of feudal economy, it is enough to be called a treasure of the town, and it is enough to influence the times.

The stability of a country depends on the living conditions of the vast majority of the people.

If the vast majority of the people can fill their stomachs, it means that the country is in a stage of stability and prosperity, and if the people do not have the trouble of starvation, then the country will be able to maintain peace and stability for a long time.

All activities such as peasant uprisings are basically because the common people cannot afford to eat.

Everyone is going to starve to death.

So take the risk and fight to the death.

But if everyone has food in their hands, then basically no one will take risks and risk the possibility of killing their heads to oppose the country, but will live their own small life in peace.

That's how important food is.

……

As long as Cao Ang can smoothly evolve wheat and corn, these two food crops, even one generation.

Being able to increase production, or adapt to the environment, is enough to give him an advantage in the next step of growing his power.

Place of the same size.

In the territory under his control, the output of grain is much more than that of other forces.

Then Cao Ang will be able to recruit more soldiers and horses as a result.

Be able to have the confidence to carry out a larger-scale decisive battle.

At that time, there will be no force in the world that will be qualified to engage in a war of attrition with him.

It's time to compete for productivity.

It is any force that will be dragged to death by him.

When the basic agricultural technology is right, it is like the roots of a tree are strong, and then the branches and branches up will naturally be able to thrive.

There is no doubt about it.

Even in the future, when the Cao family took the surname Liu and established the Great Wei Dynasty.

can also rely on such a skill.

Let the dynasty live for a hundred years, or even hundreds of years.

All in all.

It's definitely a treasure today!

……

Of course.

Something good is good.

But also put it into practice.

It is useless to stay in theory, you must find a reliable person, and gradually turn what is recorded in the book into reality.

It's just a matter of the candidate......

Cao Ang was a little embarrassed.

Such an important weapon of the country must choose a reliable person, that is, a person who can be fully trusted by him.

Secondly, you have to be capable.

Otherwise, if you just have trust, but you are confused with a book and don't know how to start, isn't it the same as being blind?

And if you have to do both.

Hiss...... It's a bit difficult!

One name after another, in Cao Ang's mind, swirled back and forth like a marquee.

Many figures emerge.

But he was quickly eliminated by him.

After thinking about it for a long time, Cao Ang reluctantly chose a few people in his heart.

But it doesn't work at all.

I'm afraid we'll have to wait for the actual investigation to find out.

Carefully closed the two books and put them back in the box.

Cao Ang closed his eyes.

Then the consciousness left the ship's surface.

…………

Early the next morning.

Cao Ang looked at Diao Chan, who was still sleeping beside him, and did not disturb her sweet dreams.

Rather, it is after gently brushing your fingertips through your hair.

Quietly collapsed.

He changed into his robe and walked towards the palace.
