Daqin: Zulong's Traveling Frog

Chapter 27: Tools for Pounding Rice
Ying Zheng opened the photo.

Little Zhinu's big eyes are always so eye-catching.

In the photo, Xiao Zhinu is standing at one end of a wooden plank.

At the other end, there is a boulder four times bigger than Xiaozhinu.

And Xiao Zhinu seems to have this natural power.

It can lift the boulder.

It seems that the little child slave is really smart.

Use the principle of leverage to lift the boulder.

Could it be that Xiao Zhinu is telling the lonely king that his strength has become stronger?

But his intuition told Ying Zheng that it would never be that simple.

Take a closer look.

Behind Xiao Zhinu is a winding river.

Across the river there was a woman singing a sweet song.

The women were singing and pounding rice.

Are the women's identities suspicious?
But the women are just like ordinary people, with flushed faces, combed hair, and dark skin.

Wearing a coarse cloth jacket, holding it with difficulty
There is nothing suspicious.

It was nothing more than a middle woman pounding rice by the river.

pounded rice
Ying Zheng's eyes widened, as if realizing something.

Combining with the little boy to use the lever principle to prop up the stone.
Pounding rice with a stone pestle consumes no less energy than a boy's farming.

What's more, from morning to night, millet has been pounded in the stone mortar.

After pounding the rice, my arms were sore and I was extremely tired.

Even a burly man is exhausted, let alone a woman?
Pounding rice does take a lot of energy.

If this method of innate supernatural power is applied to pounding rice
Making full use of the principle of leverage, the huge stone pestle is connected to one section of the wooden pile, and the woman is at the other end.

With proper measurements, a woman must have been able to lift a stone pestle weighing about one stone with very little effort.

Couldn't the stone pestle for pounding rice be enlarged several times?
Wouldn't the efficiency of pounding rice be greatly improved?
"Such a simple truth, why didn't the lonely king discover it?"

Ying Zheng looked at the photo, rubbed his palms, and said calmly.

Yes.

The wise ancients have long known the principle of leverage.

unfortunately
The principle of leverage has not yet been used in the technology of pounding rice.

However, such a simple principle was rationally used by Xiao Zhinu and applied to pounding rice.

Before spring plowing, Xiao Zhinu used a photo to improve the farming method by using fish hooks, so that the original two-oxen pull bar was replaced by a fishhook-shaped curved shaft plow.The efficiency of men's sowing has doubled, and the harvest is [-]% of last year's.

just now.

The young child has to combine the principle of leverage to change the previous method of pounding rice by hand to using wooden boards to pound rice.

Production can be greatly increased again!
No way, the productivity in the Spring and Autumn and Warring States period was low.

Especially pounding rice is a kind of torture.

What's more, girls usually start pounding rice with their strength at the age of ten, and they have been working for decades, and their arms may be useless.

A woman's youth is wasted on pounding rice.

The difficulty of pounding rice is no different from that of farming.

In the Daqin law, pounding rice was used as a punishment, which was the same as the boy's Chengdan (boys were forcibly appointed to build cities).

If he can make a tool for pounding rice lightly, then that little childish slave will be doing a great job.

"Xuan Qinmo is here!"

Ying Zheng suddenly got up, flicked his sleeves, and said loudly.

Tian Feng and dozens of others came to Zhangtai Palace again to see what new tricks Ying Zheng would come up with?

After Qin Mo stepped into the palace gate, Jishou saluted.

After getting up, Ying Zheng told Tian Feng what was expressed in the photo of Xiao Zhinu.

Fix a long piece of wood to the wooden frame, with a stone pestle at one end and an empty end at the other end.

But there is a condition.

Even with the power of the pedals, the stone pestle can be lifted and lowered.

Tian Feng frowned, looking surprised.

This kind of tool, Tian Feng has not touched.

Qin Mo was also confused, thinking that Ying Zheng was being unreasonable.

However, due to Ying Zheng's majesty, everyone could only follow suit.

But after Tian Feng thought about it, he felt that this tool was unusual.

Use the principle of leverage to lift the stone pestle.

If you put a stone mortar under the stone pestle, and with the lifting and lowering of the stone pestle, wouldn't it be easy to pound rice?

Tian Feng's eyes lit up, and a smile appeared on his face, "Your Majesty, I understand."

"Oh?"

Ying Zheng glanced at Tian Feng.

Tian Feng explained: "This method is wonderful. In the future, when pounding rice, you don't need to lift the stone pestle, you only need to step on it with your feet!"

After all, Ying Zheng smiled indifferently: "The one who knows my heart is Tian Fengya!"

Qin Mo who was around stared at him with big eyes and small eyes, and his ears were filled with mist.

Encouraged by Ying Zheng, Tian Feng turned around and explained to Qin Mo and others.

Only then did Qin Mo understand, and a bright smile appeared on his face.

Some even slapped their thighs and said, "Why didn't I think of that!"

Tian Feng immediately took Qin Mo to make tools.

In addition to making tools, Yingzheng is most worried about the cost.

Ying Zheng immediately ordered to investigate the cost of making tools.

Half an hour later, Yingzheng learned that the cost was only [-]% of the cost of pounding rice with a stone pestle and a stone mortar.

Yingzheng was overjoyed. The tadui is not only easy to make, but also cheap. It is indeed a good tool.

Another hour passed.

Tian Feng came to report that the tool has been built.

Thus, Ying Zheng came to the Imperial Garden.

With the work of several Qin Mos, huge tools were placed in the imperial garden.

Two square plates are used as supports, with a crossbeam placed in the middle, and a long wooden pole is set up. A stone pestle is installed at one end of the wooden pole, and a stone mortar is placed under the stone pestle.

According to history, this thing is called Tadu, and it was not invented until the Han Dynasty.

But Xiao Zhinu informed Ying Zheng of Ta Dui a hundred years in advance.

Ying Zheng quickly ordered people to build it, and decided to start the experiment.

Before it started, someone was whispering underground.

I think tadui is very common, and even said tadui is unremarkable.

Tian Feng looked at them coldly, angrily reprimanded everyone, and even asked Ying Zheng to behead them.

Tian Feng not only humiliated them, but also saved them.

Otherwise, Ying Zheng would definitely not be lenient.

Sure enough, Ying Zheng didn't blame him.

After all, no one is optimistic about a new invention before it is used.

Only when the experimenter personally experiences and knows the benefits of the tool will he accept the tool.

Ying Zheng couldn't wait, and wanted to know the effect of stepping on the pestle.

Can the huge stone pestle be lifted up for pounding rice by using the principle of leverage as Yingzheng thought?
Is it more efficient than pounding rice by hand?
Facing Qin Mo's disdain, can Ta Dui make their eyes shine and slap them in the face.

And comparison is the most direct way to test the results.

Under Ying Zheng's order, a large amount of corn was put into the mortar.

Tian Feng also walked towards the pedal, and was about to step on it lightly, but was stopped by Ying Zheng.

I thought Yingzheng didn't want to try it, but Yingzheng ordered people to take out a new stone mortar, gave people a stone pestle, and pounded rice by hand.

Only in this way can the effect of treading be highlighted.

at last.

Ying Zheng started the experiment.

In the imperial garden, there was a muffled sound of stone mortars and pestles colliding.

Ying Zheng became increasingly nervous.

Can treading be like Quyuanli, bringing convenience to the people and benefiting the country and the people?
It's just that at the beginning, the speed of manpower pounding rice is faster than that of treadmill?
Did the little boy make a mistake this time?
