Qin Huaidao and Cheng Chuliang started their careers as contractors. This was a novel experience for them. No matter how unwilling they were to accept it, they could only bite the bullet to avoid Li Ming's snitching at this moment.

.

And after explaining the matter, Li Ming.

He didn’t treat him as a completely hands-off shopkeeper, but continued to be busy in the Shaofu.

This time he hired some carpenters.

After two days of tinkering, a tool slowly took shape.

And this is a unicycle.

Wheelbarrows are commonly known as "chicken carts", "second in command" and "dirt carts".

The wheelbarrow uses the lever principle to move the load's resistance point closer to the fulcrum (i.e., the wheel) to make its own operation more efficient. It also shares the load between the wheelbarrow and the operator, because the wheelbarrow makes it easier to move bulky or large loads.<

/p>

It was distributed in many parts of the country in later generations. Before the popularization of modern transportation, it was a light vehicle for transporting goods and people. Especially in the north, it almost played the same role as the donkey.

Cross hoes, wheelbarrows, and gantry cranes were extremely common in infrastructure construction in previous generations.

It can even be said to be an artifact.

However, even if it is a cross hoe, he currently does not have enough iron tools for him to squander, and the only thing he can use is a wheelbarrow.

Although there have been unicycles in China for a long time, compared with the unicycles of later generations, the unicycles of this era still have flaws here and there.

So Li Ming directly used the knowledge of signing in to create this new type of unicycle.

Compared with the old-fashioned wheelbarrow, it is not only more stable on flat ground, but also has higher maneuverability in places where balance is easy to be lost, such as small, paved or tilted roads. More importantly, it is easier to unload.

Control.

"Build a hundred of these wheelbarrows and remember to send them to the engineering team within ten days."

After speaking, Li Ming gave instructions casually.

"No!"

Several carpenters responded quickly.

Although ten days is a bit of a rush, considering the size of the Shaofu, building a hundred aircraft within ten days is not a big problem.

And after arranging these things.

Li Ming immediately went to check again.

Chicken and duck farms, as well as earthworm breeding sites.

More than a month has passed.

The scale of chickens and ducks has not continued to grow on a large scale, but has been in a relatively stable state.

The chicken and duck giveaway activities are still going on.

Now it has gradually spread to the entire Guanzhong.

A large number of people have already received chickens and ducks.

Although it is not completely free, it is almost enough. After all, a chicken or a duck only needs to be returned. In the eyes of most simple people, even if there are risks, it is impossible to kill them all.

This is naturally very fast.

In this kind of large-scale gift.

All the chickens and ducks are consumed quickly, so it is naturally impossible to expand the scale.

As for earthworm farming.

It has expanded a lot during this period.

The number of earthworms has also reached a terrifying level, and can basically feed 100,000 chickens and ducks.

Now that it has been moved to the entire Shaofu, perhaps the only thing that has not been able to develop is pig farming.

The little piglets he bought before have now grown up.

However, Li Ming shows no signs of expanding.

There is no way, in this era there is not enough food for the people to eat, so there is no leftover to raise pigs.

Although pigweed can be fed, the growth of pigs fed with pigweed is too slow.

Li Ming also had to restrain his thoughts.

I also temporarily suppressed the sacred book.

We can only wait for the subsequent fermentation of locusts.

Or wait for something better to sign in to.

And it seems that the system heard his voice.

When the sunshine shines the next morning.

Announcing the arrival of a new day.

Check in as always.

"Sign in!"

"Sign in successfully!"

"Congratulations on obtaining ten pounds of potato characteristic No. 1301 experimental variety!"

There was a flash of white light, but Li Ming didn't pay too much attention at first.

"Potato?"

He muttered to himself, a little confused, but soon when he saw a small bag of yellow lumpy objects appearing in front of his eyes, his pupils instantly widened.

"Potato, potato!"

The words blurted out almost uncontrollably.

At this moment, even if he is calm enough, he cannot calm down at this moment.

Potatoes.

He never expected that at this moment he would actually sign into Tudou.

Compared with everything before, this thing is a true artifact.

There is no exaggeration.

Because potatoes are fully worthy of this title.

Compared with rice, wheat, even millet, and potatoes in this era, they are truly high-yielding grains.

Nowadays, the yield of rice per acre is only more than 300 jins, and the yield of wheat and millet is even lower, only about 2,780 jins.

How much potatoes can be produced in a year?

Under normal circumstances, the yield of potatoes per mu is about 2,000-5,000 kilograms; the yield of non-repeat crops is higher, up to about 8,000 kilograms; with some good potato varieties, coupled with scientific management, the yield can even reach tens of thousands of kilograms per mu.<

/p>

Although this is in the future world, in this era without pesticides and fertilizers, it is basically impossible to achieve a yield of 10,000 kilograms per mu, but a thousand kilograms per mu is not a big problem.

Especially the potato in front of you is no ordinary potato.

But an experimental species.

With his right hand, he picked up an instruction manual that appeared next to it.

The text on it comes into view.

Li Ming instantly understood where these potatoes came from.

This is a product of the laboratory.

Compared with ordinary potatoes, it has a higher yield and stronger disease resistance.

More importantly, it will not degenerate as it reaches the next generation, and if nothing else happens, it will retain its characteristics forever.

Obviously, this has greater advantages than ordinary potatoes.

Even Li Ming was looking forward to this moment.

Nowadays, although the Tang Dynasty has gone through nine years of recuperation and recuperation during the reign of his cheap grandfather, production and life have basically recovered, and food is no longer as scarce as it was originally.

But food is extremely important in any era.

More important than money.

Whether a dynasty can be stable or strong depends on its grain output and reserves.

If a country wants to be strong and prosperous, food is indispensable.

And in this way, in other words, it seems to make sense.

That is to say, if there is more grain production, the national power will naturally become stronger.

Thinking of this, his eyes glowed even more when he looked at these potatoes.

National power, that is national power.

Eyes filled with excitement.

The next moment, Li Ming no longer hesitated, picked up the ten kilograms of potatoes, and quickly headed towards the Shaofu.

With this artifact.

Of course he was a little impatient at this moment.
Chapter completed!
