Who is not Cao Cao?

Chapter 121 Fertilization, the beginning of a new study

When He Yan was thinking about how to minimize the loss, he realized that Yang Xiu was still waiting outside.

"Mr. Yang!"

This sound was extremely cordial.

After all, 500 million dollars!

Cao Cao can get Hongnong Yang's wool, why can't he do it himself?
He Yan's enthusiasm gave Yang Xiu goosebumps all over his body, but when he thought of his mission, he still bit the bullet and dealt with He Yan.

"Dare to ask Marquis Shen, this new learning..."

"The main point of this new study is the unity of knowledge and action!"

He Yan taught Yang Xiuyan by example: "The first step is to plant the land!"

Yang Xiu: ...

--------

--------

Time: In the fifth year of Jian'an, at three o'clock on the day of Renxu in the twelfth month of winter.

Location: On a piece of farmland on the outskirts of Xuchang.

Characters: He Yan, Ren Jun, Yang Xiu, Cao Pi, and some soldiers who don't have lines to serve as background boards.

Yang Xiu blushed slightly, and asked He Yan who was beside him: "Marquis Shen, are you cold?"

"not cold."

"why?"

"Because we're all sane."

Except for Yang Xiu, everyone else was wearing thick cotton gowns (the inside was not cotton, but silkworm), looking at Yang Xiu who was only wearing a short shirt like a fool.

"Ah!"

Yang Xiu sneezed heavily: "I thought common people would wear shorts when they went to work in the fields..."

"It's true to wear short clothes. The question is who wears short clothes in winter?"

Regarding Yang Xiu's performance of "meat eaters are contemptible", He Yan has long been unable to complain.

"Cao Pi, give him your cotton robe!"

"do not want!"

Cao Pi held on to his clothes tightly, guarding against the possibility of robbing them at any time.

"Hurry up! Otherwise, Langzhong Yang will really freeze to death!"

He Yan looked at Cao Pi dissatisfied: "And don't think I don't know, you are wearing three cotton robes! A young man full of anger, wrapped so much to be careful of getting sick!"

Only then did Cao Pi reluctantly take off a cotton robe outside.

Yang Xiu wanted to go up and take it gratefully, but Cao Pi immediately scolded Yang Xiu: "Don't move!"

After taking off another cotton robe from inside, Cao Pi handed the inside cotton robe to Yang Xiu: "Here! The inner one is warmer."

Immediately, Yang Xiu was grateful for the flow of tears (or possibly the wind), and thanked Cao Pi for a long time.

But He Yan, who had already seen through the truth beside him, narrowed his eyes.

The reason why Cao Pi gave Yang Xiu that... probably because the cotton robe on the outside looks better than the one on the inside, right?
but.

With Cao Pi's temperament, he was able to say "the one inside is warmer than the one outside" to buy people's hearts, which is obviously a great improvement.

"Could it be that Jia Xu has already started teaching Cao Pi?"

……

When He Yan was struggling with this matter, Yang Xiu finally put on his cotton robe, wiped his nose and came to He Yan's side and asked, "Marquis Shen, what is it that called us here today?"

"That's right! He Yan! Why did you pull me out?"

Cao Pi's resentment is obviously much stronger than Yang Xiu's.

"Also! What did you say to dad last time when you went back? Why did dad whip me with a horse as soon as I went in?"

He Yan glanced at Cao Pi: "The reason why I called you here is to see that you have been bored in the Sikong Mansion these days, and I want you to come out to get some air. If you don't want to, you can go back by yourself!"

Oh open?

Cao Pi thought about it carefully, and found that since Cao Cao came back, he had indeed strengthened his restraint, and even sent Jia Xu to be his teacher.

In this way, Cao Pi has indeed never been out of the Sikong Mansion a few times, and he is very restrained.

So Cao Pi immediately showed his big white teeth and applauded He Yan: "He Yan! You are righteous!"

This time, it was Yang Xiu, Ren Jun and others who looked at Cao Pi with the eyes of fools...

He Yan also nodded in relief, and secretly breathed a sigh of relief: "It's okay! Even if Jia Xu goes into battle, he can't save Cao Pi! Very good!"

"Cough cough."

After comforting Cao Pi, He Yan said to Yang Xiu, "The main reason for calling Doctor Yang this time is to experience the newly learned "unity of knowledge and action."

"The so-called "what is learned on paper is always superficial, and you never know that you have to do it yourself", this new learning emphasizes that everything must be done by yourself."

He Yan looked at his uncle Ren Jun at this moment.

Ren Jun stepped forward and pointed to the two fields under his feet: "These are the two fields that Marquis Shen asked me to find on purpose."

"There is no difference in water and soil between these two fields, but last year's harvest was [-]% different!"

Thirty percent?

Yang Xiu also frowned after hearing this number.

Thirty percent is naturally not much in one field, but what about one mu?What about an hectare?Or even hundreds of hectares?
This gap is enough to send out the grain of a large county. This is no joke.

Ren Jun didn't give a shit, but gave the answer: "Although these two lands are used for farming, one of them often goes to the river to pick some grass pond mud to spread in the field, and the other has not picked it. Grass pond mud!"

Yang Xiu understood now, the difference in harvest lies in the grass pond mud.

"However, Marquis Shen... what does this grass pond mud have to do with Xinxue?"

Not to mention the relationship with Xinxue, even the overall increase in grain production has little to do with it.

After all, grass pond mud is limited, and the government will not allow large-scale excavation of grass pond mud, otherwise there is a risk of even the river course breaking its embankment.

If you want to use grass pond mud to increase food production, it would be a bit whimsical.

He Yan was not surprised by Yang Xiu's question.

On the contrary, He Yan also showed an expression of "as expected".

Scholars educated by Confucianism are always like this "landlordism" when they see something.

People who have no morals will think: "Is this thing useful to me?"

People with a little more integrity will think: "Is this thing useful to others?"

At the most, you will think: "Is this thing useful to the court and the people?"

Only when a ready-made thing is put in front of their eyes, will they begin to think about and extend it.

But as for the essence of this thing... Sorry, this is not something these "scholars" and "masters" have to think about.

He Yan sighed, and asked Yang Xiu, "Mr. Yang, this is not the case with new learning."

"Let me ask you, do you know why this grass pond mud can increase the grain production?"

Not to mention Yang Xiu, even Ren Jun, a small farming expert, was a little dazed about this question.

Why can grass pond mud increase grain production?
Maybe there was just one person who poured some grass pond mud into his field, and when the crop yield increased, everyone started to follow the trend and throw grass pond mud into their fields.

As for why, no one will think about it.

In other words, even if you think about it, the answer is the so-called sage's words in the book, telling them what the universe is, what the prehistoric universe is...

Their answers are so vast that even the heavens and the earth cannot accommodate them, but it is very difficult to solve such a pile of dark grass pond mud.

Yang Xiu, Cao Pi, and Ren Jun all surrounded him, crouched beside He Yan and began to think about this question.

"Because the soil in the grass pond mud is different from the soil here!"

The clever Cao Pi took the first step on the right path, which is very good!

He Yan looked at Cao Pi with relief, and decided to reward him for his father's care.

"But what's the difference?"

"It seems that the grass pond mud is darker?"

"Not only black, but also smelly! There is a faint smell of grass mud!"

"Indeed, I remember that Cao Zhang once went to the river to play with grass pond mud all over his pants, and my mother suspected that he had pulled his pants pockets!"

"Really? Has the prince pulled his trouser pocket?"

"of course not!"

"What about Marquis Shen?"

……

"Hey!"

He Yan, who couldn't bear it anymore, kicked Cao Pi and Yang Xiu's ass hard, which brought the topic back to the topic.

"The smell should be the smell of rotting aquatic plants."

"Yes, I heard that some farmers let some weeds grow on the side of the grain, and they will turn these weeds into the field in the spring. In this way, the grain seems to be more prosperous..."

……

Even Ren Jun joined the discussion, and the three of them actually sorted out some principles when they talked about each other, which made them all find it interesting.

"But... the rotten grass leaves have disappeared, so why is it still increasing food production?"

The three of them got stuck in this place and couldn't make progress, all of them frowned.

"Because the rotting blades of grass don't actually disappear."

At this time, He Yan picked up a hoe, knocked it hard into the ground a few times, and dug out a rotten blade of grass.

"Water, gas, and more that we don't see, but are actually things that are absorbed by the crop later to fuel its growth."

"Something invisible?"

"Yes, unseen things. But they do exist."

After hearing He Yan's answer, Yang Xiu pondered for a while and asked, "The new study is to study this?"

"Get rid of some miscellaneous things, the essence is to study this."

Yang Xiu was a little puzzled: "Since you can't see it, why do you have to study it so hard?"

"If you can't see it, does it mean it doesn't exist?"

He Yan raised his head: "Power, fame, none of these things can be seen, but does Yang Langzhong dare to say that they don't exist?"

"Many people in ancient and modern times have been studying power, but in the end it was nothing but nothing."

"But if anyone has figured out the substances that make crops grow, then this person must be the same as these substances. Even if they decay and wither, no one can deny his immortality."

"So, Langzhong Yang understands?"

The cold wind fluttered, but it didn't suppress He Yan's words. Everyone present clearly heard the "immortal" words.

Yang Xiu wasn't as relaxed as before, but frowned even tighter: "Is this new learning?"

"This is new learning."

This new learning... is different from what Yang Xiu knew before coming here.

After he chose to enter the pit, he had already read "New Explanation of the Book of Changes" and "Mencius".

These two books are indeed remarkable, and their core "searching things to gain knowledge, uniting knowledge and action" is even more exciting, but in Yang Xiu's opinion, compared with academic value, its political value is obviously more.

But what He Yan said today opened a whole new door for Yang Xiu.

"Only such knowledge can be defined as new learning!"

If it was said that Yang Xiu just wanted to dawdle in the pit of new learning before, but now he wants to dig deep into it!
Seeing Yang Xiu like this, He Yan was also filled with pride.

Seeing that Guo Jia had just slipped away before, He Yan still had some doubts about his ability to sell ships, thinking that smart people are not easy to fool around.

But now it seems... that's not the case!

Cao Pi also moved over suspiciously: "What's new?"

"It's a very new thing, I'll teach you when I go back."

……

Now Yang Xiu returned to the question of the grass pond mud: "How to find the invisible substance that can increase grain production as mentioned by Marquis Shen?"

"practice."

"Lots of practice!"

He Yan gave the answer.

"Until the law is discovered, there is only practice."

"Just like the deduction of astronomical phenomena in "New Interpretation of the Book of Changes", if there are no historians who have recorded astronomical phenomena for hundreds or even thousands of years, it will be difficult for us to know what the truth is."

"If it is said that "investigating things and extending knowledge" was done before, then what is done later is the real "integration of knowledge and action"."

He Yan spoke heavily, but he began to chuckle in his heart: "Except for cheating!"

Now He Yan, is to help this Huaxia, open the first cheat!
As for whether to dominate the entire server or be banned...it all depends on luck.

"Other things need to be practiced, but I really heard about the mud in the grass pond from a friend of mine."

He Yan finally revealed the real purpose of calling Yang Xiu and Cao Pi: "We can use the method of decomposing to make manure!"

After manure or livestock manure is retting, fermenting, and decomposing, the substance Yang Xiu mentioned can be obtained.

The garrison soldiers under Ren Qi's command lifted up the excrement they had prepared early and placed it at the feet of Yang Xiu and Cao Pi.

The strong smell made the two young masters almost faint, and Cao Pi slipped away directly.

Yang Xiu covered his nose and said, "Marquis Shen, can this really make something like grass pond mud?"

Yang Xiu and Cao Pi now sincerely want to say sorry to Caotangni.

Compared with these feces, how can the grass pond mud smell?It is very fragrant!

He Yan did not give Yang Xiu's affirmative answer, but said: "Try it and you will know? Could it be that Langzhong Yang has forgotten the newly learned horoscope."

"Study things to know, is knowledge and action united?"

Yang Xiu slowly put down his hand covering his mouth and nose: "Marquis Shen, what should I do?"

"Simple!"

What He Yan wants to teach everyone is the "simmering dung method".

If it's a bit more indecent, it can also be called "burning shit"...

The method is to mix mud with dung first and build a hollow mound.

Afterwards, firewood was put in and burned inside, so that there was heat all around.

In this way, through this method of "mixing mud and burning it to detoxify the heat", manure that can be fertilized can be produced.

Easier said than done.

Especially in the first step, mixing the dung and soil together will give people a great psychological obstacle.

Yang Xiu stared at the pile of dung, staring at himself a little nauseatedly, but still hesitated to do it.

"Mr. Yang! Unity of knowledge and action! Unity of knowledge and action!"

He Yan thoughtfully provided Yang Xiu with refueling service, and Yang Xiu finally stretched his hand in after a lot of struggle.

"Yuck~~~"

Yang Xiu was fine, but Cao Pi, who had been standing by, vomited out first.

"He Yan! I want to go back!"

Cao Pi has already retreated, saying that he can't do it at all.

"Oh."

Cao Pi originally thought that He Yan would use [-] ways to make him stay, but He Yan actually agreed to him to leave?
"Go back, anyway, you'll just sit there and study, you can figure it out yourself."

"..."

Cao Pi was really entangled.

Reading, or playing with shit?
It's so hard to choose!

After hesitating for only a second, Cao Pi came to Yang Xiu's side, and a fierce man inserted his hand in!
Only ghosts want to study!

Even though it's shit, it's still fun, isn't it?

Seeing Yang Xiu and Cao Pi happily playing with dung together, He Yan felt even more relieved.

"Xinxue has you~ Then I can rest assured!"

Ren Jun also came over at this time and asked in a low voice: "Yulang, is this... really useful?"

"It's definitely useful! Uncle can make more manure. I can't say that next year's harvest can be increased by [-]%, but at least it will grow by [-]-[-]%. There is absolutely no problem."

"And with manure, the method of crop rotation can naturally be implemented to increase production."

The method of crop rotation refers to planting crops in rotation in a field within a year.

For example, you can plant the millet first, then plant the millet after the millet is harvested, and then plant the millet after the bean is harvested...

Because of the problem of soil fertility, even though the method of crop rotation had been implemented as early as the Western Han Dynasty, it was not easy to implement it in a field for a long time, lest the land lose its fertility and become a poor field.

But if there is this manure, naturally there is no need to worry about excessive consumption of land fertility, and one can safely and boldly implement crop rotation.

Ren Jun's eyes lit up after hearing He Yan's opinion: "If it is true what Yulang said, I am afraid that next year's grain production will double!"

"That's not likely, but the growth is definitely certain."

With more food, the lives of the people will be better, and Cao Cao's power will be stronger.

For example, in this battle of Guandu, if after Cao Cao burned Wuchao, Yuan Shao and Wuyang Wuyang transported hundreds of thousands of shi of grain, even if the gods descended to earth, there would be no way.

And similarly, if Cao Cao's power is stronger, the duration of this troubled world will be shorter.

"The rise of this new learning has never been a solar eclipse that fools people."

"It's the countless grains that will grow from the ground in the future!"

He Yan turned his head and looked at the busy Yang Xiu, Cao Pi, and many soldiers in the fields.

"The beginning of the new learning is not in the house of Hua Xin's house, not in "New Interpretation of Zhouyi", not in "Mencius", but here!"

From then on, the roots of Xinxue... have really penetrated into this soil, and began to brave the storm and stubbornly declare war on this world!

When He Yan was planning the future of Xinxue, Yang Xiu and Cao Pi had already built a hollow mound.

Although Yang Xiu was full of stink, he was very happy: "The new learning is really amazing! The unity of knowledge and action! What a unity of knowledge and action! In this way, when the harvest is harvested next year, everything will be known!"

Cao Pi was also very happy at first, but when he saw He Yan, who was empty-handed, and the field soldiers around him who were also building earthen furnaces, he still asked something that puzzled him——

"Yang Langzhong, even if we don't do it, can't the surrounding field soldiers also make clay furnaces?"

Yang Xiu: "..."

Damn!It makes sense!

I didn't think so? ? ?
