In Annan County, near the inn where Gu Changsheng and Yin Xian and others lived.

This is the fifteenth day after Gu Changsheng took Yin Xian and others to Annan County.

In the past half a month, their group has almost run through Annan County, and they can basically see the situation of the farmland around the capital today.

Take the dots and the surfaces.

Although Gu Changsheng didn't dare to exaggerate, he could know the situation of farmland and farm tools in the world from here.

But a few things are certain.

For example, the plough used by the Great Zhou Dynasty now is still quite backward in Gu Changsheng's opinion, and it is still in the era of the straight plow.

There is also the waterwheel, which has not yet been applied and promoted, and more irrigation only relies on manpower and animal power to draw water to irrigate the fields.

In addition, the methods of fertilizing the fields are also quite simple.

It didn't have much of an increase in yield.

Such discoveries made Gu Changsheng more and more motivated.

Those agricultural technology trees in his mind can indeed come in handy in this era!

And.

Gu Changsheng's eyes looked out the window, and an imperceptible smile flashed in his eyes.

He could feel that tonight, the number of people watching around this inn was more than half.

"It seems that the people of these big families don't have a lot of patience!"

"Huh?"

Hearing Gu Changsheng's emotion, Yin Xian and the others were stunned: "My lord, what are you talking about?" ”

"It's fine."

Gu Changsheng waved his hand.

He cultivated the "Great Grade Heavenly Immortal Jue", and his spiritual sense was far beyond that of Yin Xian and the others.

And the manpower arranged by the Zhang family and the Mo family to keep an eye on them is also quite hidden.

Gu Changsheng could detect it, but Yin Xian and the others were difficult to judge, so there was no need to tell them too clearly.

Gu Changsheng waved his hand and asked Yin Xian and the others to rest first, while he returned to his room, sat at the table, took a piece of rice paper in front of him, and began to reminisce.

Actually, after this half-month investigation.

Gu Changsheng also discovered a lot of agricultural technology that could be used.

But compared to [Waterwheel] and [Quyuan Plow].

The rest of the tech trees, the improvement effect that can be brought is not huge.

This is one of them.

The second is because those agricultural technologies can wait until Gu Changsheng cleans up the wealthy families in these places first, at least weakens them, and then implements them.

Otherwise.

These agricultural technologies have been released too much in one go, and it is likely that they will not bring much improvement to the lives of the people and the annual harvest, but on the contrary, these powerful clans have gained a wave of great benefits!

This would go against Gu Changsheng's original intention.

"First of all...... The case of the straight plow. ”

Gu Changsheng held the pen in his hand and groaned slightly, which was based on the actions of Yin Xian and others these days, and he had estimated a rough idea.

Under normal circumstances, the general straight plough of the Great Zhou, two people rotate, plus a cow, and one day down, can probably drive three to five points of land.

Again, this is based on the fact that cattle don't need to rest.

If you include the rest days of the cattle.

Then the efficiency of arable land is even lower.

Therefore, most of the people of the Great Zhou are now under the protection of the Great Clan.

Even if they have land, they often sell it to large households, and it is because of these large clans in the local area that they have more cattle.

Otherwise.

Relying only on his own family, he is just a cow.

After a spring ploughing, the cattle will not be tired to death, but will also be tired of disease, not to mention, where will there be a farmer with a cow in every household? Many of them involve several families buying a cow.

In this way, the disease rate of cattle is naturally higher.

And once the cattle die of disease, there is no cattle to help, only relying on manpower, the efficiency of ploughing the land in the next year will be slower, and so on, after a few years.

Even if you don't want to sell your land or become a tenant farmer, you will be forced to sell your land and become a tenant.

"But if you can transform the straight plough into a curved plow......

"One person a day, one cow, it only takes one day to be able to reclaim, at least three acres of land!"

This efficiency is not an exaggeration.

In fact, three acres of land is still said to be less.

In Gu Changsheng's memory, the Quyuan plough can allow a normal strong laborer to reclaim five acres of land or more in one day.

It is ten times more efficient than the current straight plow!

Once this can be realized, at least the livelihood of these farmers will be guaranteed.

Why is it that the power of the powerful clans in the local area is so great that it is difficult to contain.

It is because, even if the government comes forward to restrict these powerful clans from annexing land, in the face of natural and man-made disasters, ordinary people who are difficult to compete with each family will one day be unlucky and will not be able to turn over directly.

When the time comes.

The Haoqiang clan does not buy land, but it forces these desperate people to embark on a dead end.

But this is not to excuse the powerful clans.

After all.

The people who were forced to join the tenants did not live a good life.

It's nothing more than extending the date of the end of the road by a few years.

When Gu Changsheng took Yin Xian and others to travel around Annan County, in half a month, he saw too many miserable conditions for those tenants to live!

Gu Changsheng's eyes flashed.

"If the Quyuan plough can be implemented, the people's farming efficiency can be improved, a family, the land that can be cultivated has increased, and in the face of risks, the confidence to be able to compete will be more sufficient!"

This is the gain of the curved plow.

And outside of the Quyuan plow, there is another big killer prepared by Gu Changsheng, that is, the waterwheel!

Gu Changsheng raised his pen and began to sketch on another blank piece of rice paper, and soon, he drew three different waterwheel drawings.

Of these three waterwheels, one is a common automatic waterwheel.

One is an animal-powered waterwheel pulled by an ox.

There is also a pair of high-barrel waterwheels that are specially used in Gu Changsheng's memory in places that are far away from the water source.

These three waterwheels can cope with three different geographical environments at the same time.

The existence of the waterwheel can also greatly save manpower and animal power, and the waterwheel also has an advantage, that is, a waterwheel can irrigate at least half of the village's fields at the same time!

The cost of the waterwheel is much higher than that of the curved plow.

But its significance is much more important than the curved plow.

This is also an important reason why Gu Changsheng also took out the waterwheel and prepared to plow it with the curved yuan, and at the same time implemented it at the earliest!

"The ability of a household to resist natural and man-made disasters is too weak."

"But what if there is more than one family that unites to fight against those natural and man-made disasters?"

In Gu Changsheng's eyes, there was a bright light!

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