The twelfth year of Yuanheng is a very iconic year.

This means that for the first time, the people of Datang have been slowly released from the hard work of facing the loess with their backs to the sky.

It was also extremely strange for the people to see the steam tractors that made whining noises working in the fields.

After the surprise, it was like an African savage who saw the compound bow of the later generations, and his face was full of surprise and joy that could not be concealed.

This thing is horrible.

In the past, two or three acres of land, even if there was a cow at home, it would be tiring enough.

And......

Cattle are such livestock, although they are hard-working, but sometimes, they also make a temperament and don't want to do it.

Besides, if it were a hot day, the cows wouldn't be able to stand it.

However, there is no such problem with steam tractors.

A steam tractor can plough dozens or hundreds of acres of land for you in one go.

"In the past, this thing could only be seen in the army, and it was used in Tuntian, but I didn't expect that it can be seen here now."

】

There are young people who have been government soldiers and have seen this thing, so they opened their mouths to popularize science to others.

"This thing really ploughs the land quickly, and it seems that it has only been half an hour of effort, and it has been ploughed from one end to the other."

"This is all Your Majesty's compassion for the people of our Wangjia Village!"

After that, the village was about to bow down in the direction where Li Chengqian was.

The children were also staring at this black thing, crossing their waists, "Brother Heizi, have you ever driven this thing?" ”

The young man called Brother Kuroko said, "Nonsense, I can open it with my eyes closed." ”

After a short while, the steam tractor was driven up in front of them again, and the child was able to observe the thing more closely.

Then he asked the other party very curiously, what is it for.

This sunspot also knows everything.

Other than that......

Kuroko also learned by talking to the person who drove the steam tractor that it was free this year.

Cough!

What this means, it seems needless to say.

But......

It's not bad, anyway, it can save this year's effort, isn't it?

It only took about ten days to plow the fields around Luoyang to be planted with wheat by steam tractors.

Many aristocratic officials, tourists, scholars, and even some noble ladies in the Tang Dynasty couldn't help but come out curiously to see this thing.

The reaction after reading it was......

I really don't know if I don't see it, and I'm shocked when I see it.

Many of them may not know that Datang can still have such a powerful thing.

After all......

Not everyone has the opportunity to go to Liaodong, or to Shanzhou and the Western Regions to see the most realistic scene of steam tractor farming.

Now......

They finally met.

Isn't this thing more powerful than a hundred cows plowing the land?

Let's just say that it's a bit scary.

In fact, as long as you have seen a steam locomotive, then this steam tractor should not feel too unfamiliar.

It's just that......

A steam locomotive is a steam locomotive and a steam tractor is a steam tractor.

Even if it is applied to the same principle.

But this can still bring them a lot of shock.

After all......

This cultivated land is being cultivated too quickly.

As a result, when the steam tractor was plowing the fields, it attracted countless prostitutes and literati to come and watch.

This can be regarded as a picture that seems to be ahead of its time.

……

And Li Chong's words......

Of course, he wouldn't be so bored and go to farming.

He planted it himself.

This year......

His onions are also clearly a 'big harvest'.

In his experiments with potassium fertilizer, the resulting onions were, on average, about one-fifth larger than other onions that had not been dosed with potassium.

Li Chong felt as if he had mastered the true meaning of fertilizer synthesis.

In fact......

Fertilizer is not so difficult to be honest, anyway, whatever ions the plant needs, just give it whatever ions.

Of course!

If a lot of sulfate and chloride ions accumulate in the ground, will it lead to soil acidification?

This question can only be said...... Li Zhong understands that the fertilizers of later generations are definitely not so simple.

It must also be taken into account that the pH balance of the soil must not be disturbed.

If it is destroyed in the future, maybe it can be repaired and restored.

But if it is destroyed now, then Li Chong himself does not guarantee whether he has the ability.

But......

The realization that even the simplest chemical compound has the power to act as a fertilizer is enough to satisfy Li Zhong by relying on that.

But I don't seem to know why, maybe it's because of the technology and hard work.

Even if this is an onion grown by himself, to tell the truth, Li Chong still doesn't dare to say anything.

After all......

Who knows if this potassium sulfate and potassium chloride are poisonous.

To complete this experiment...... Cough!

Li Chong could only let the pigs eat and try.

When the pig finished eating, there seemed to be nothing wrong, and when the sheep was changed, there was nothing wrong.

At last......

That's what makes people eat.

Of course, you can't use your own people.

So......

Li Chong asked Li Angran for a few slaves and maids from the Wa Kingdom.

Cough!

Don't blame him for being ruthless, I can only say that he will remember them if he dedicates himself to science.

After Li Angran and the others saw Li Chong's letter, they also wondered if it was a letter written by his own Aye.

Merely......

Don't they know what kind of taste they have?

They just like women!

It's just a little unexpected, they Aye are so old, they can still have such interest.

After all, it's himself Aye!

Now that Aya has opened his mouth, as a son, he can't be unfilial.

Thereupon......

Soon, Li Angran and the others specially selected a few good-looking and passable ones for Li Chong and sent them to Luoyang.

Many women in the Wa Kingdom say that they are powdered and black-toothed, like monsters.

But in fact......

It is said that these black teeth are only specially painted with those black things in order to protect their teeth.

But none of that matters.

The letter said that it was for a few, but how many were it for?

The four of them discussed it again, and simply sent five of them over.

"It's disrespectful to the old!"

"Send five of this, can Ayeh take it?"

"No, what if a child is born at that time?"

"Forehead ......"

It can only be said that this sentence woke them up all at once.

However......

It doesn't seem to be a big problem, after all, you can drown directly if you are born.

Although it is very inhumane.

However, the safest thing should be the only one.
