"It's easier said than done to liberate the labor force!"

Li Er is not very optimistic about this, after all, this is an eternal problem.

Although they have been making improvements to the plough, it still hasn't been solved much!

"Your Majesty, don't worry, there will be an invention soon!"

Zhao Yin smiled mysteriously.

"New inventions?"

Hearing this, Li Er immediately stood up from the dragon chair.

Every time this kid makes a new invention, it will make Datang take a step forward, which makes him look forward to it.

"But this new invention was not made by my son-in-law!"

"Who's that?"

Hearing that he didn't invent it, Li Er was even more puzzled.

"It's Lin Wu, he is currently working on a steam tractor, and when this machine comes out, it will no longer require so much manpower, cattle and horses to cultivate the land, and the efficiency can be increased dozens of times, and the liberated labor force, Your Majesty can naturally immigrate at will!"

Zhao Yin began to introduce them to the power of tractors.

"Is that true?"

Li Er was really taken aback.

He didn't expect that someone other than Zhao Yin could invent such an artifact.

"Can the son-in-law still deceive His Majesty?"

Zhao Yin nodded firmly.

"In this way, not to mention immigrating three million, even five million is no problem!"

The eldest grandson Wuji clapped his hands happily.

"Datang has such an artifact, why not develop rapidly?"

Dai Xuan also stroked his beard with relief.

"But ......! When will it be developed? ”

Although this artifact is good, it is useless if it is studied for too long.

"The slowest is only three months!"

Zhao Yin added another month on the basis of what Lin Wu said.

After all, after the research is out, it will be debugged!

"Quick! Xuanlin Wu entered the palace, I want to ask in person! ”

Li Er waved his hand at Wang De behind him.

"Yes!"

Wang De gave up his hand, did not dare to delay for a moment, and trotted out all the way.

After the immigration issue was resolved, other ministers began to report to other government affairs, but Zhao Yin was not interested in these at all, took out a small thin rub from his bosom, and trimmed his nails in public.

After the early dynasty, Li Er called a group of henchmen to the imperial study, and after drinking a cup of tea, Lin Wu finally arrived.

"The horse said that you have a new invention that can liberate countless laborers in the Tang Dynasty, but is there such a thing?"

After Lin Wu gave a salute, Li Er asked straight to the point.

"It's the horse master who is modest, if there is no horse master, the minister can't study the tractor, and even the drawings are drawn by the horse minister!"

Lin Wu arched his hand, not daring to take the credit for himself.

"What is a tractor?"

Like Lin Wu, after hearing this new word, they all looked at him suspiciously.

"That's the name the pony gave to this new machine!"

"Oh!"

"With this tractor, the efficiency of farming can really be increased dozens of times??

Dai Xuan couldn't wait to ask.

Of course, this is also the issue that Li Er and others are most concerned about.

"This question, Master Ma will know better than the lower officials!"

Lin Wu smiled and looked at Zhao Yin.

As his gaze shifted, everyone turned their attention to Zhao Yin.

"Of course you can, if this tractor is developed, it can not only be cultivated, but also transported!"

Zhao Yin nodded firmly.

Datang is now vast and sparsely populated, and what is most lacking is this kind of mechanization!

"Great, haha......!"

Li Er laughed happily, "Is it true that this machine can be developed in just three months?" ”

"It's three months at most, but if you want to mass produce, at least until the end of the year, this year's spring ploughing can't catch up!"

In this regard, Lin Wu still felt a little regretful.

"It doesn't matter, as long as this kind of machine can be successfully developed, let alone the end of the year, it doesn't hurt to wait for another two years!"

If you want to increase the population of Datang, it will take at least ten years, but if the machine is produced smoothly, the labor force can be liberated in advance.

"With this machine, the immigration problem will be solved this time!"

Dai Zhou was also happy about this.

Only by letting the people of the Tang Dynasty enter the northern Xinjiang one day earlier, can it be regarded as truly belonging to the Tang Dynasty.

"That's right, Dai Aiqing, you can start planning the issue of immigration now, where to move, how much to move, and make a plan before the end of the year!"

After arranging this matter, Li Er suddenly felt a lot more relaxed in his heart.

"Yes!"

Dai Xuan stood up and bowed.

The census was conducted by him and the local government, so he knew best how to move the people.

"Lin Wu, you also have to pay close attention to the development of the tractor, any manpower and material resources you need, you can talk to me, and you must ensure that the development of the machine goes smoothly!"

The importance of tractors, Li Er naturally knows, and he will not be stingy when it comes to business.

"Obey the order!"

"With this tractor, the cultivated area of Datang will definitely increase, and when the time comes, the people will not be able to eat all the grain produced every year!"

Dai Xuan folded his fingers and calculated, and said with a grin.

"It's just...... I wonder how much this tractor costs? ”

Just when everyone was hopeful about the tractor, Wei Zheng asked a crucial question.

Although the people have a little money in their hands now, they have not yet reached the point where every family can buy a machine!

"This is to the point, if this machine is too expensive, the people can't afford it!"

Fang Xuanling also agreed.

This is undoubtedly pouring a basin of cold water on Li Er on the spot, pouring it out of the cold!

"How much does it cost?"

Li Erhu looked at Lin Wu suspiciously, and Lin Wu set his eyes on Zhao Yin.

He didn't dare to call the shots for such a big matter.

If it is said that it is less, when it comes to mass production, the money approved by the household department is not enough!

If you tell the truth, I'm afraid that Li Er and others will stop R&D because the cost is too high!

"You can make a rough estimate!"

When Zhao Yin saw his embarrassed expression, he understood what he was thinking, and said with a smile.

"About ...... Four or five thousand, right? ”

Lin Wu thought for a moment and said a slightly vague number.

However, the machine has not yet started production, and no one can say how much it will cost in the end!

"Don't say 5,000 guan, just hit the lowest 4,000 guan, and the people can't afford it!"

Hearing this, Dai Xuan spread his hands, and all the hopes he had just had turned into nothing.

And everyone else here also looked at him, looking helpless!

"If an artifact like a tractor is developed, it must not be sold only at cost price!"

However, Zhao Yin's words dealt them a heavy blow.

"Then how much more do you kid want to sell?"

Hearing this, Li Er immediately became anxious.

According to his meaning, he wants to take advantage of the fire to rob!

"At least six thousand!"

Zhao Yin stretched out his thumb and little finger and compared a six.

"Even if the people can't afford the lowest 4,000 guan, let alone 6,000 guan, I think even if this machine is developed, it will be in vain!"

Cheng Yanjin waved his hand, which meant that there was no drama in this matter.

"It takes time and cost to study machines, and there's nothing wrong with making some money from them, besides, there are still a lot of things to study in the future, and money is needed everywhere!"

Zhao Yin said as a matter of course.

"Is there anything else you kid can do? Let's talk about it! ”

Although Li Er was angry, he then thought about it, this kid never did something he was not sure of, and it was impossible for him to say this idea knowing that the people couldn't afford it.

Presumably he still has his own plans!
