The distant mountains were withered and yellow, dotted with white, unmelted snow, and looked like witch's hair.

At the quarry, the wind whirls and whirls, pouring gusts of wind into the boiler through clay pots, blowing charcoal fires to make them burn more vigorously.

Red fire, white gas, busy people, in this ice and snow has not completely melted in the early spring, so that this season has not yet fully warmed up, become vibrant in advance.

"Open the furnace!"

The second senior brother, who had been transformed from a blacksmith into a coppersmith, shouted loudly, and the idle people on the side went to the side, moving a piece of open space to avoid being accidentally injured by the copper water containing high temperatures.

Seeing that everyone dodged away, the second senior brother who had successfully lost weight scooped up the viscous copper juice with a special pottery spoon, put it there, leaving only a small hole on the mud fan, and after tilting it, poured the copper juice along the hole into it.

The second senior brother with great strength had a very steady hand, and a spoonful of copper juice was poured into the hole, and there were few spills, which was much better than when Han Cheng was at the beginning.

Heiwa's eyes widened, and her two hands unconsciously clenched the animal skins she was wearing.

Spoonfuls of copper juice were poured down, and thirteen of the fourteen plowshare models placed here were poured with copper juice.

The reason why the rest of the stove is not filled is because the copper juice in the furnace is not enough to fill a clay fan, and if it is poured in, it will waste a clay fan in vain.

This kind of mud model is not easy to do, and it is natural to waste one less to waste one.

However, the rest of the copper juice did not let it cool down like this, but poured two small copper knives out of them.

"Click~"

This combination, leaving only one hole to pour bronze juice into it, is not only cumbersome to make, but also basically cannot be reused.

If you want to take out the solidified bronze inside, there is no other way to use it, but to break the outer mold and the inner fan.

Although it is more distressing to break the mold that has been painstakingly made, Heiwa did not have much softness when she got up, and when she picked it up and fell the ground, the outer layer of the bronze plowshare that was poured first had already collapsed.

The mud flakes flew around, revealing a piece of yellow light.

Heiwa quickly found a small crowbar made of bronze, and poked off the mud chips that stuck to it and refused to leave, and a plow larger than the palm of a perennial man appeared in his hand.

The ploughshare is yellow and shiny, and it looks good, and it doesn't look like there are many flaws.

"Miko!"

After looking at it for a while, Heiwa held the plowshare that she had finally made, and ran to Han Cheng's side excitedly, showing it to Han Cheng like a treasure, cheerfully like a child.

Han Cheng took the long-lasting, hard-won plowshare from Heiwa's hand with a smile on his face, and took it in his hand to look at it carefully.

Compared with the iron plowshare that he saw in later generations, which was whitened by the earth, the bronze plowshare in his hand was much rougher.

And in size and weight, it could not catch up with the iron plowshares he saw in later generations.

The reason why the ploughshare is so small is that the bronze is relatively brittle, and the casting is too large, which is easy to be damaged when ploughing the land.

On the other hand, the deer in the tribe have little strength, and the plowshare casting is too large, and the deer cannot pull it.

When Han Cheng looked at the plowshare, the Wu and others here also came here, using deer to plough the land, and the good use of bronze tools, they had all experienced it personally.

Combining the two at this time, the effect is exciting.

The people were eager to put the bronze plough on the plough now, and then lead the deer up to the field and plough it to see for themselves how it worked.

"Haha, good!"

Although the plowshare in his hand is rough and simple compared with the iron plowshare of later generations, he does not lack the plowshare that he should have.

There is no problem with cultivating land.

After Han Cheng looked at it carefully for a while, he laughed out loud, and then reached out and patted the shoulder of the black baby with an expectant face, and praised it from the bottom of his heart.

The black baby, who was already in a good mood, got better after being praised by Han Cheng, and it was more beautiful than eating braised pork.

Then there was a crackling sound.

This is the remaining twelve models that have been smashed.

There were thirteen plowshares in total, and a defective product appeared in them.

The reason why there will be defects is because when the second senior brother poured bronze into this model, the first spoon was not full, and the second spoon was continued.

Copper juice and other metal liquids solidified very quickly, and this short delay caused a fault on the bronze plowshare.

Han Cheng took it in his hand and looked at it, and slammed it the stone, and the bronze plowshare immediately broke into two.

Of course, the ruined bronze ploughshare was reluctant to be thrown away, and when the next pot of copper was smelted, it was put into the furnace and melted down with the rest and used again.

"Puff puff ......"

In the few houses of the Qingque tribe that did not have pankangs, there were some people around, and the carpenter was lame, holding an axe in his hand and chopping at the bottom of the wooden plow.

After cutting for a while, he took the plowshare he had at hand and put it on top to compare and see what was not suitable, then he removed the plowshare from the top and continued to rest.

"Dangdangdang......"

After some rest, the lower end of the plough finally fits the plowshare, and the limp puts the plough down on the ground, so that the lower end of the plough is facing up, and then puts the plough on it.

Later, he found a wooden plank and put it on top of the plow with one hand, and with the other hand he held an axe and smashed it down at the plank.

The reason why a wooden board is padded is because the wooden board is relatively soft, and it is blocked in the middle as a buffer, which can protect the bronze plowshare from being smashed by the iron axe to the greatest extent.

After a dozen axes went down in succession, the plowshares were tightly attached to the wood.

Lifting the wooden plough up and putting it away, Han Cheng felt the plow handle behind him for a while, and nodded with satisfaction.

Simple, of course, is still rudimentary, but with a bronze ploughshare, the plough immediately looks more presentable.

Sure enough, people rely on clothes and horses to rely on saddles, and even plows are decorated with metal.

After waiting a little longer, I will make a bronze plough wall, and put a clip on the plowshare, and after fixing it, the plow will become more presentable.

Once a plow is loaded, there are people who can't wait to see the effect.

Without the plough wall, the soil ploughed up by the plough will not run to one side, and the effect of the plough is not very good, Han Yuan didn't want to carry the plow to the ground at this time, and wanted to use the complete plow to do the experiment after the plow wall was finished, but when he looked up, there were expectant eyes around him, and after thinking about it, he nodded and agreed.

In fact, deep down, he really wanted to see the effect of the bronze plow.
