It is enough for Da Zhou's agricultural taxes to increase by 30% or more.

Such a treasure.

If it can't be called a "artifact of national rejuvenation".

Even these officials of the Ministry of Industry can't imagine that there is anything else in this world that is qualified to be called such a treasure!

But.

After listening to their opinions and ideas, Zhang Ran's face did not show a satisfied smile, but was a little disappointed: "You guys, do you only see such a thing?" ”

What about increasing production by 30% or 50%?

Those yields, how much?

In Zhang Ran's opinion.

The design drawing of the waterwheel sent by Gu Changsheng is really used properly and well deployed.

It's enough to directly double Da Zhou's agricultural income!

"Flip ...... Double!? ”

Hear the words of your own heavenly official.

This time.

Not to mention the officials of the Ministry of Industry next to them.

Even Yin Xian and others came to deliver the letter, and these officials of the Divine Patrol Division were a little uneasy.

Although I know that this old official Zhang Yuan is quite concerned and optimistic about his own adults.

But the praise of this old heavenly official is inevitably too exaggerated!

Even Yin rewarded them, they were all praised at the moment, and they were a little empty-hearted, right?

Doubling the tax on agricultural products throughout the Great Week.

This kind of thinking.

They don't even dare to have it when they are dreaming!

Looking at the wonderful expressions of Yin Xian and the others, Zhang Yan twisted his beard, looked at the disbelieving faces in the room, and smiled slightly.

Now.

Zhang Yin calmed down and didn't continue to blame his subordinates.

After all, didn't you see that even the "own people" of the Inspector Division who sent this design didn't realize the importance of the waterwheel?

Zhang Yin thought and sighed again.

Patting everyone on the shoulder, he motioned for everyone to look at the few blueprints he had specially picked out, spoke in a deep voice, and said quietly, "Take a look." ”

"These blueprints are right in front of you."

"What they are aimed at, whether it is mountainous or dry land, these terrains, in the past, in many cases, have they been abandoned, and they are really only a few?"

Hearing Zhang Yuan's seductive words.

The officials of the Ministry of Industry present, and even Yin Xian and others, were stunned.

Immediately.

One of them counted as one, but they all shivered together, and they all had the feeling of waking up like a dream.

Looking at the design drawings of the waterwheel in front of me, the eyes are all different!

"Yes!"

"Before, there were still a lot of dry lands and mountains in my big week, and I couldn't use them."

"Even if it takes generations of hard work to reluctantly reclaim new fields, cultivating on this kind of terrain will be tiring and tiring in a few years, and it will not be easy to have a good harvest, a year or two is fine, three years, five years...... As the days go by, there will always be a day when these fields will be abandoned! ”

But now.

After having a waterwheel.

Whether it is dry land or mountainous land, they all have the hope that the yield per mu of the field is on par.

And so it goes.

These waterwheels, after being developed.

Not only can it greatly increase the grain output of the Great Zhou Dynasty and the existing acres of land.

It can also make many areas that could not be used as cultivated land before also be reclaimed as cultivated land, and truly realize the scene of turning wasteland into farmland!

"Even if these are these, the harvest of five acres of newly reclaimed wasteland can be worth the harvest of one acre of old land!"

"How much is my big Wednesday Thousand Prefecture Mansion?"

And, a place.

Mountainous land, dry land, and other wastelands that are difficult to use for cultivation often account for much more than arable land.

Once the waterwheel is popularized, many people dare not say that the states and governments will be able to increase their current tax fields and trees by 30% or even 50%.

Definitely not a problem!

Then calculate the yield increase effect of the waterwheel on the existing farmland.

It is said that the agricultural tax will be doubled throughout the Great Zhou.

This is definitely not an exaggeration!

After listening to Zhang Yuan's explanation.

The officials of the Ministry of Industry present were all completely enlightened.

The officials of the Ministry of Industry who were the first to react were quite excited.

Because of the undisguised appreciation in Zhang Yuan's eyes when he looked at them.

Let them all be secretly excited.

And Yin Xian and others are already a little stupid.

They really didn't expect that their own adults asked them to send this design drawing to Tianjing City would have such far-reaching significance.

And after coming back to his senses.

In their hearts, they are also quite a little and have a sense of honor!

Just when their hearts are stirring.

When Zhang Yin finished sighing.

But he reacted, his eyes fell on Yin Xian and the others, and he said with a smile: "Your lord said before that he wanted to transfer the master of the Tianzi brand of my Ministry of Industry to help him." ”

"I don't know, but he wants to ask my master craftsman from the Ministry of Engineering to come over and help him build a waterwheel?"

Hearing Zhang Yin's words.

Many officials of the Ministry of Industry present were all excited.

All of their eyes lit up, and they all looked at Yin Xian and the others, with boundless longing and amplitude in their eyes.

I can't wait for Yin Xian to immediately say a word.

After all.

Now anyone with a discerning eye can see who can participate in the development of this waterwheel.

In the future, you will be able to achieve unimaginable feats and qualifications.

And if the Ministry of Industry sent a master craftsman at this moment, he would go over to help.

Officials of all sizes in the Ministry of Industry will be able to share the profits of this credit.

This makes them, how can they not be tempted.

But.

Yin Xian shook his head again and again.

Let them all be instantaneous, disappointed to the extreme.

But.

Not waiting for them to hang their heads.

Hearing what Yin Xian said later, they were all excited again!

"Back to my lord, when Lord Gu sent me to wait, he didn't say that he invited the master to come over to make a waterwheel."

Yin Xian thought of Gu Changsheng's advice.

Hurriedly said: "My lord said that he wants to transfer craftsmen to him, and there are many other agricultural tools to be made on his side." ”

"Moreover, the adults of my family also specially asked me to tell you Tianguan, the meaning of those farm tools, even if they are not stronger than waterwheels, they will definitely not be worse!"

"What!?"

Hearing Yin Xian's words.

Zhang Yuan didn't answer yet, but the officials of the Ministry of Industry next to him were completely unsettled.

The appearance of the waterwheel, in their opinion, is already the supreme luck and the supreme opportunity.

They even started to think about it.

Do you want to go back, send a letter, and tell Gu Changsheng about their admiration and gratitude.

As a result, now, Yin Xian opened his mouth and said, that Gu Changsheng Gu, there are several farm tools, the value is not much worse than the waterwheel?

Some people died, but not completely......
