Chapter 274: Efficiency increased by more than ten times.

Speaking of the foot-operated threshing machine, Chaochao couldn't help but move forward a little so that Daqi people could see it more clearly.

Seeing this, Jian Yunsang simply picked her up.

Then the narrator laughed and said, "This kind of threshing machine was developed in the 1970s. It has a wooden drum with iron teeth, gear pedals on both sides, and is linked by a crankshaft. Two people stand side by side to pedal the drum, and it can thresh up to three acres a day."

Three mu?
The people of Daqi stared wide-eyed, their breathing quickening.

Wouldn't three mu (approximately 0.33 acres) be six times more than a threshing bucket? Some families with little land can finish threshing in just one or two days.

The farmers of Daqi stared intently at the threshing machine in front of them, their eyes clearly conveying one message—they wanted it!
The narrator continued, "Not only did the threshing capacity increase significantly, but the labor intensity was also greatly reduced. It didn't require strong laborers; it was entirely possible for children to hold the bundles of grain while adults pedaled the threshing machine. It even reduced spillage losses to less than 5%, and the threshing rate was over 90%. Therefore, this type of threshing machine was very popular in the 1970s and 80s."

The people of Daqi became more and more excited as they listened. How wonderful it would be if they also had such convenient farming tools!

As Jian Yunsang listened, she carried Chaochao around the threshing machine twice, allowing the Daqi people to see it more clearly.

However, the people of Daqi, who were initially excited, gradually calmed down and then became somewhat disappointed.

The roller is inlaid with iron teeth. Iron is such a precious thing. Even if the imperial court really made it, they... most likely couldn't afford it.

They were so focused on their surprise at the daily threshing volume that they didn't even notice the words "iron teeth".

These days, even a simple iron hoe costs eight hundred coins, let alone such a large threshing machine, which must cost at least ten taels.

Many farming families might only have a dozen or so taels of silver left even if they took out all their savings.

Are we really going to use all our money to buy a farm tool? Let's just use our labor to do the work.

Emperor Jingxuan's expression was also somewhat solemn. Iron teeth were fine, but what was really difficult to popularize was the bearing in the middle, which looked heavy and substantial, somewhat like the axle of a carriage wheel.

Wealthy families can certainly afford it, but these are farm tools, and the people who need them are those who are not well-off. If the price is set too high, they simply cannot afford it.

Even just by looking at it, you can tell that the cost of this thing is not low.

The officials inside the hall were also discussing in hushed tones. After a long while, the Grand Tutor stepped forward and said, "Your Majesty, can this bearing be replaced with something else?"

Yu Kang Sheng sighed, "If that's the case, the axle definitely won't be very fast, and it will require a strong person to step on it to turn it, so the efficiency will be low, and it certainly won't be able to thresh three mu of grain per day. The people might not know how to use it."

That's true, so this matter needs to be considered carefully.

Emperor Jingxuan wanted to hear if there were any better threshing machines, but the narrator continued talking, which only made him more envious.

The narrator said, "However, this kind of foot-operated threshing machine was gradually phased out after the 1990s. Later, diesel and gasoline threshing machines appeared, which could thresh grains on 10 to 13 mu per day. And now, with the combine harvester, harvesting, threshing, and cleaning are integrated, and the daily work volume exceeds 50 mu. Technology is advancing, and our lives are getting better and better."

The people of Daqi gasped. How much?
Fifty mu?

And that includes harvesting, threshing, and washing—fifty acres a day? That's outrageous.

If that's the case, these ordinary people wouldn't even need half a day to harvest all the rice.

They didn't even need to worry about the weather, didn't need to rush the harvest, and probably... didn't need to expend much effort. No wonder people in later generations seem to have it so easy; how did they come to have such useful machines?

Emperor Jingxuan didn't even want to express his envy; he was immediately stunned.

It seems that development before the foot-operated threshing machine was very slow, and even if there was progress, the effect was still not significant. However, this process took more than two thousand years.

However, after the advent of foot-operated threshing machines, it seems that every ten or twenty years, a new type of threshing machine is developed, and the effect is ten times greater.

This is too fast.

Just then, the commentator said with a smile, "Since the country started to vigorously develop technology, in less than a hundred years, our country has changed dramatically. Take this threshing machine in front of us, for example. It has evolved from a foot-operated threshing machine to a combine harvester in just thirty or forty years. That's incredibly fast."

Emperor Jingxuan and his officials held their breath. The technology had only been developed for less than a century? The daily threshing capacity of the threshing machine had increased from three mu to fifty mu in just thirty or forty years?

Jian Yunsang couldn't help but laugh when she heard the commentator's words.

Without even thinking, she knew how much regret and envy the people of Daqi would feel upon hearing such data.

She took Chaochao around twice, allowing her to examine the place more closely.

Seeing this, the commentator said with some speculation, "If you want to know the internal structure, there are blueprints here."

The people of Daqi were invigorated. There were even blueprints?

Jian Yunsang followed the guide's finger and indeed saw detailed blueprints in a glass cabinet not far away.

She led Chaochao and Feifei over, and the two little girls looked through the glass case. Although they couldn't understand it, they chattered excitedly, and it looked quite convincing.

Emperor Jingxuan hurriedly asked, "Did you write it down? Did you write it down?"

"Your Majesty, I have written it all down."

Emperor Jingxuan nodded repeatedly, saying that the iron problem could be discussed later, and that it was more important to memorize the structure first.

Jian Yunsang guessed that Daqi Ren should have seen enough, so she led the two children inside.

There were many small farm tools at the entrance, such as hoes, carrying poles, winnowing baskets, wooden buckets, raincoats, and straw hats, which were not unusual to the people of Daqi.

However, Chaochao and Feifei rarely saw this kind of thing, so Jian Yunsang led them slowly, listening to the guide introduce each one.

The two girls came to broaden their horizons. Feifei was initially in low spirits, but as she listened to the guide's introduction, her attention gradually shifted.

Before long, the group arrived in front of a stone statue.

The guide explained, "This is Song Yingxing, an inventor from the Ming Dynasty. His book, *Tiangong Kaiwu* (The Exploitation of the Works of Nature), records various production techniques, including agriculture and handicrafts. It details the entire process from raw materials to finished products, and includes illustrations. If you two children are interested, you can take a look at it when you get home."

Tiangong Kaiwu?
Ming Dynasty?

Emperor Jingxuan suddenly raised his head and asked, "Didn't they mention before that the Great Qi period is equivalent to the later Ming Dynasty period?"
