Shuang Daqin comparison, no comparison, no harm

Before.

The time was not ripe enough, and the Qin State did not have reliable iron use.

Now.

With the advent of low-carbon iron.

A lot of things, Zhao Ze can take out.

Examples include cocoons and curved ploughs.

Thereupon.

Zhao Ze got up and patted his butt and led people to the Industrial Construction Institute.

Saw Zhao Ze’s appearance.

All the craftsmen gathered around as if greeting the God of Wealth.

Syllable!

Zhao Ze took a sketch.

“This is a curved sickle!”

In fact, the Warring States already have a sickle.

But.

Because I don’t understand the principles of mechanics, the scythe made by the craftsmen at this time is a straight sickle.

Look.

It’s like a ruler.

And this straight-to-go structure is easier to build and simple to work.

Craftsmen are also happy to make sickles.

The sketch taken by Zhao Ze is a curved sickle.

It’s just that the blade is slightly bent to the inside.

But the effect.

But at least three times better!

“Scythe?”

The craftsmen watched curiously.

It looks like a straight sickle, not much difference!

It’s just a lost arc!

Syllable!

Zhao Ze took another drawing.

“This is a chainsaw!”

As a matter of fact.

The saw has long been invented.

The inventor is the originator of the craftsman of Lu Guo, and Lu Ban made it.

Reputedly.

When Luban went up the mountain, his legs were cut by a kind of grass.

He plucked the leaves of the grass and found that the edges of the leaves were serrate, which is why it could cut through human skin with a soft body.

So Luban rushed home.

Immediately imitated the leaves, made serrations.

But it’s well known.

In this era, bronze was too soft and hard enough to be used to make serrated cutting things, which was difficult to achieve.

And iron?

It has a high carbon content and is fragile.

A wooden stick was sawn, the stick was sawn open, and the iron saw was also broken.

So.

Craftsmen don’t like to use iron saws.

Too inefficient.

It is not as practical as the big one with an axe, and the small one with a carving knife.

Now the State of Qin has low-carbon iron.

The hardness and toughness are enough to take out the iron saw and promote it.

“Iron saw?”

The craftsmen were stunned.

Isn’t this thing already there?

“It’s different, look at the sawtooth.”

“My serrations are positive on one side and oblique on the other, making it effortless to use.”

Zhao Ze explained.

The sawtooth at this time is also because of not understanding mechanics.

So the serrations created are oblique on both sides.

The sawtooth looks like an acute triangle, while Zhao Ze uses modern zigzag and looks like a right triangle.

It saves effort when used.

And the cutting effect is also better.

Syllable!

Before the craftsmen could react.

Zhao Ze took out the grass paper of the Quyuan plough again.

“This is a curved plow!”

Equally.

Ploughs have long been available as agricultural tools.

However, everyone uses a straight plow, and what Zhao Ze took out is an improved Quyuan plow.

The curved plough is equipped with a free-rotating ploughshare on the bridle head, which can make the overall plough frame smaller and lighter, and also facilitate U-turns and turns, making the operation more flexible.

It can save a lot of manpower and livestock.

It is much inferior to the steel behemoth cultivator, but the Quyuan plow that appeared in the Tang Dynasty was definitely explosive in the Warring States period!

I haven’t waited for the craftsmen to study it.

Syllable!

Zhao Ze took another sketch.

“This is a columb!”

The car was born in the Western Han Dynasty.

That is, the Western Han that destroyed the Qin State and established the Han Dynasty.

There are still more than a hundred years before the appearance of the cocoon car.

But Zhao Ze doesn’t mind letting the car appear in this world in advance.

The people now.

Bend over when sowing seeds.

Peel the soil and sprinkle in the wheat seeds.

Cover the soil.

Compacted vigorously.

But with the cocoon.

When sowing seeds, only a cow is needed to pull the cart, and the cocoon can open a ditch and sow seeds on the level land, and at the same time cover and suppress, saving time and effort, so its efficiency can reach “one hectare per day”.

Until the age of technology.

It is also used in some remote mountainous areas.

You can see how practical it is!

Four drawings in a row.

Let the craftsmen of the industrial institute be overwhelmed.

They didn’t even understand the curved sickle, and as a result, Zhao Ze took out the iron saw, the curved plow and the cocoon car!

Each drawing is enough for them to study for several days.

“Changgongzi, how long do you want us to make these things?”

Some craftsmen asked with difficulty.

“Three days, no more.”

Zhao Ze muttered.

It’s just a sample, these dozen people add up, it is certainly not difficult.

“Good! Eldest son! ”

Feeling that there was plenty of time, the craftsmen also breathed a sigh of relief.

A few days later.

Huan Zheng took Zhao Ze’s hand and came to the farmland.

He picked up the curved sickle.

Walk towards the nearby grass, hold a handful of weeds in your left hand, and hold a knife in your right hand and pull gently.

Whaa

Effortlessly.

Just cut a handful of weeds.

If it is a straight sickle, it is estimated that it will take a lot of effort!

This scene.

Let the surrounding people secretly surprise.

The scythe is only slightly bent, which can save so much effort?

After that.

Wouldn’t it be easier for them to harvest rice and wheat?

Ying Zheng was also bright, and continued to test the next tool, the iron saw.

He found a wooden stick with a thick arm.

Walk over and start sawing back and forth.

A moment later.

Iron saws saw through wooden sticks.

Click.

The stick is broken in two.

The cut surface is also very flat!

“Easy to use, save effort!”

It’s much easier than picking up an axe and slashing it.

Then.

Ying Zheng aimed at Quyuan Plough again.
