"I can go so deep."

Cao Ang checked the ground, it was not easy to be so deep.

Zhang Ming threw away the dirt, and then said, "What else? ”

"The soil turned up is even finer. No need to do it twice. ”

Zhang Ming led them to the side of the straight plow.

"Look, this straight plough still needs to be manually broken up with the soil, and this plough is not deep enough, sometimes it needs to be turned two or three times."

Sun Ce didn't know about the straight plow, but Cao Ang knew it very well.

Indeed, as Zhang Ming said.

Just looking at this, the efficiency of the curved plough has been several times higher.

However, there is still a problem, that is, this cow can pull multiple levels.

Don't bend the plough ox, pull for a while and you will be tired and paralyzed, and you can't pull it, then there is no point.

The people were walking in the fields.

Qu Yuan plough is far ahead.

Keep going for a mile or so, then change directions and come back.

Zhang Ming took them to compare as they walked.

Where the curved plough pulls through, it has always been very balanced.

The straight plow has just finished one trip, and the curved plow has already finished two trips.

Moreover, the curved plough has always maintained its speed.

Cao Ang and Sun Ce were shocked.

Especially Cao Ang, he is a connoisseur.

He even doubted that he would become an agronomist.

This Cao Ang has always been a doer, Cao Cao asked him to go to Tuntian, and in order to do a good job, he personally went to the ground and did all kinds of things.

The group walked slowly, and the contrast between the two sides was too obvious.

Cao Ang also has a lot of straight ploughs under his hands.

If you can replace it with a curved plow, it means that you can have twice as many oxen to pull the plow.

What reason is there to refuse this technique?

No, there's no way to refuse.

An hour later, the curved plow was still pulling, and the oxen of the straight plough were already a little out of order.

Zhang Ming said: "It has been proved that the quyuan plow is more efficient and more labor-saving, and the oxen of these straight ploughs are also randomly selected, and there is no difference." ”

"The straight plough is laborious, and the oxen are naturally tired."

Zhang Ming asked people to stop and gathered the cows and people together.

The peasants of this zigzag plough have already changed a batch.

There is no way to change people, the cow walks too fast, and the person consumes more physical strength.

And because the oxen of the straight plough is slow, the farmer does not need to change it.

"Efficiency, judgment."

"Dismantle two pairs of curved ploughs, and bring two pairs of straight ploughs."

Zhang Ming asked people to dismantle it, and one of them was simply disassembled.

"Prince Cao Ang, Wu Hou, this curved plow is easy to turn, and it is very suitable for the southern paddy fields."

The fields in the south, unlike in the north, are large and very flat.

Some fields in the south are not straight and monolithic.

Cao Ang even had to try it himself.

If this thing is taken to the south, it will definitely greatly improve the efficiency.

Cao Ang could even concentrate a few thousand head of cattle to reclaim a large amount of farmland and grow food for millions of people.

Can't refuse.

Cao Ang said: "Liaohou, we want to go to the place where this Quyuan plow was made. ”

"Okay, I'll take you there."

Zhang Ming and his entourage went to the place where the Quyuan plough was made again.

Cao Ang observed carefully, if it weren't for the fact that this place was not his own territory, he would even have to get started and make one himself.

It is not very difficult to watch the craftsmen make it, and after they go back, they can gather the craftsmen and produce them on a large scale.

A day passed, and Zhang Ming took them to see the whole process.

Sixteen million dollars are in hand.

This was able to build the road for the army to spend about two months.

"What do you think?"

On the way back, Zhang Ming asked again.

Cao Ang said: "Liaohou Dacai, it is really a blessing for the people to be able to make such a thing." ”

Sun Ce asked: "Liaohou, that plowshare is all good iron, and Liaohou is really an extraordinary person." ”

What kind of good iron, Zhang Ming uses steel.

He used steel as a plowshare.

Now, Zhang Ming has been able to make a large amount of steel, so he naturally wants to use steel.

"I also sell this plowshare, how much quantity you need, how much price you need, you can go to the people below to discuss, I don't care about this matter."

Sell, the finished steel can't be sold, they will go to build weapons, and the finished plowshares can be sold.

If they have the ability, they will buy the plowshare, melt it and turn it into a weapon.

In that case, the cost can increase exponentially.

After going back, Sun Ce and Cao Ang declined Zhang Ming's banquet, and the two went to the Tanglin Restaurant to eat by themselves.

When he arrived at the private room and ordered food, Sun Ce asked: "Gongzi Cao, what kind of existence is this Quyuan plow, and according to your calculations, how much can it be improved?" ”

Sun Ce has never been to the ground, and most of the internal affairs are handled by others, and he doesn't understand it.

Cao Ang said: "What Liaohou told us before is not an exaggeration, this thing can greatly improve efficiency, we can't do without it, and we have to make it on a large scale." ”

"But I've also carefully observed, Liaohou's plowshare, we can't make it well, we make it ourselves, I'm afraid the efficiency will be reduced, but it's also much faster than the straight plow."

"What does Cao Gongzi mean?"

"From Liaohou, we will buy plowshares separately, and we will make them on a large scale when we go back, and we can quickly open up a large amount of farmland, and as long as we plant rice in the last season, we can earn this money back."

Sun Ce nodded, in this way, he should indeed buy it.

Sun Ce asked again: "Gongzi Cao, how much should we buy?" ”

"Hey, let's buy 20,000 first, we can't get so many ploughing cattle now, and the biggest constraint now is ploughing cattle."

"I only have about 3,000 ploughing cattle under my command, and I need to replace them with quyuan plows as soon as possible, so I plan to buy the finished products directly and replace them all."

"After that, buy some, replace all the straight plows in the hands of the people, and as long as the people have oxen, they will send the curved plows."

Sun Ce nodded, he felt that Cao Ang's method was very good, and he could increase production as soon as possible.

Cao Ang had a good understanding of the situation under his rule, and he had been assisting Cao Cao in handling internal affairs.

And Sun Ce doesn't know much about internal affairs, and his subordinates Zhang Zhao and others are dealing with it.

Sun Ce also plans to buy thousands of finished products directly and go back.

The two exchanged opinions, and Sun Ce understood the role of Qu Yuan plough better.

At the same time, he learned a lot of methods from Cao Ang.

Cao Ang's tuntian was very effective, and a large number of paddy fields were opened up in the south.

"Wu Hou, before I came, my father hoped that the two of us could reach some kind of tacit understanding, you know, if the general trend is today."

Sun Ce shook his head lightly and said, "The Marquis of Liao has a great favor to my family, and it is definitely not possible to stand with you at this time." ”

"Of course, but you have to be kind enough to us."

Sun Ce knew this, at least Sun Ce would not attack Cao Cao from behind, and would not cooperate with Zhang Ming to attack them.

"I heard that Zhou Gongjin is also here, why haven't I seen it for so many days?"

"He took his little sister around to play."

Zhou Yu is not going to play, but this time, he needs to stay for a long time, and Zhou Yu wants to investigate it comprehensively.

From the city of Beiping, to the counties below.

This Sun Shangxiang is relatively wild and can't stay, so he followed.
