The entire grain drying ground was covered with corn from eight hundred mu of land. The yield per mu ranged from five hundred to seven hundred jin—more for fertile land, less for poor soil.
Estimating an average of six hundred jin of grain per mu, there was a total of four hundred fifty thousand jin of grain here.
After subtracting the portion they’d processed yesterday, there were still about four hundred thousand jin left.
A large machine could thresh about eight thousand jin of corn per hour, and there were two of them. Gu Jiaojiao’s small machine could handle another fifteen hundred jin per hour. At that rate, it would take about twenty hours to finish all the corn with the machines.
By comparison, it would take the several hundred villagers seventeen or eighteen days to do the same. A simple calculation like this made the thresher’s advantages obvious.
And because the results were so impressive, when Gu Jiaojiao arrived at the grain drying ground, she was met with unprecedented enthusiasm.
"Gu Zhiqing is here! Let me tell you, this thresher is just fantastic. How on earth did you come up with something like this? It not only saves time and effort, but it gets the kernels so clean."
It was even cleaner than when they shucked them by hand. There was no need to double-check their work at all.
When doing it manually, they sometimes had to use their hands to get the stubborn kernels off.
Hearing the villager’s words, everyone else immediately nodded in agreement.
"Gu Zhiqing is really something else."
It was the first time they realized farm work could be this easy.
In previous years, threshing all this grain would have stripped the skin from their hands. But this year was different. All they had to do was step on the pedal, and the corn was threshed. It took hardly any effort at all.
When someone got tired of pedaling, another person would immediately take their place. The tired worker would then go shuck some corn by hand for a while. By rotating like this, no one felt tired in the slightest.
Gu Jiaojiao smiled and said, "I saw it in a book and then tinkered with the idea myself. I didn’t expect I’d actually manage to build one."
’Gu Jiaojiao didn’t dare claim she was the first to invent it. In reality, things like this already existed; they just weren’t in widespread use yet. The equipment being developed out there was far more advanced than anything she could imagine.’
Hearing this, the crowd couldn’t help but look over at Wu Cuizhi with smiles on their faces.
Gu Jiaojiao stood and waited. Soon, she saw Leng Yuan walking over quickly, pushing a flatbed cart.
She had seen other people pushing these carts before; it usually took two or three men to move one. But Leng Yuan, his arms taut and his body brimming with strength, was moving faster than a cart pushed by three people.
’She had no idea where this man got so much strength.’
But as Leng Yuan drew closer, Gu Jiaojiao immediately went to help him.
Leng Yuan, however, dodged her.
"Don’t touch it. It’s a bit heavy, you won’t be able to push it."
Gu Jiaojiao felt a little snubbed.
She was indignant, but she also knew her own limits. So, she just waited on the side for Leng Yuan to set the cart down before walking over.
