The distant mountains are withered and yellow, dotted with white spots. That is the snow that has not melted, and it looks like a witch's hair.

At the quarry, the wind was whirring, sending gusts of wind through clay pots into the boiler, blowing the charcoal fire and making it burn more vigorously.

Red fire, white gas, and busy people are surging in this early spring when the ice and snow have not yet completely melted, making this season, which has not yet fully warmed up, become full of vitality ahead of time.

"Open the furnace!"

The second brother, who had transformed from a blacksmith to a coppersmith, shouted, and the idle people nearby moved aside, leaving some open space to avoid being accidentally injured by the high-temperature molten copper.

Seeing everyone move away, the second brother who had successfully lost weight scooped up the sticky copper liquid with a special ceramic spoon and placed it on the clay mold, leaving only a small hole. After tilting it, he poured the copper liquid into the mold through the hole.

The second brother, who was strong, had steady hands and poured a spoonful of copper liquid into the hole with little spillage, which was much better than Han Cheng's at the beginning.

Heiwa's eyes widened and his hands unconsciously clenched the animal skin he was wearing.

Spoonfuls of copper liquid were poured in, and thirteen of the fourteen plowshare models were filled with copper liquid.

The reason why the remaining one is not poured is that the copper liquid in the furnace is not enough to fill up a clay mold. If it is poured in, a clay mold will be wasted in vain.

It is not easy to make such a clay mold, so the better to waste it, the better.

However, the remaining copper liquid was not allowed to cool down. Instead, it was used to cast two small copper knives.

“Crack~”

Compared with a single mold, this mold, which is assembled with only one hole left for pouring bronze liquid, is not only more difficult to make, but also basically cannot be reused.

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

Although it was painful to break the mold that he had made with great effort, Heiwa did not show any mercy when he broke it. He picked it up and threw it hard on the ground. The outer layer of the bronze plowshare that was cast first collapsed.

Amid the flying mud pieces, a patch of brilliant yellow light appeared.

Heiwa quickly found a small bronze crowbar and poked away the mud that was stuck on the surface. A plowshare that was slightly larger than an ordinary person's palm appeared in his hand.

The plowshare is bright yellow, very beautiful, and it doesn't seem to have many flaws.

"Son of God!"

After taking a quick look at it, Heiwa ran to Han Cheng excitedly, holding the plowshare that he had made with great difficulty, and showed it to Han Cheng like a treasure, as happy as a child.

Han Cheng took the plowshare, which took a long time to make and was hard to come by, from Heiwa with a smile on his face, and looked at it carefully in his hands.

Compared with the iron plowshares that he saw later, which were whitened by the soil, the bronze plowshare in his hand looked much rougher.

Moreover, in terms of size and weight, it was not as big as the iron plowshares he saw in later generations.

The reason why the plowshare was cast so small was, on the one hand, because bronze is relatively brittle, and if it was cast too large, it would easily be damaged when plowing the land.

On the other hand, the deer in the tribe were weak and the plowshares were too large for the deer to pull.

When Han Cheng was looking at the plowshare, Wu and others who were here also gathered around. They had personally experienced the benefits of using deer to plow the fields and bronze tools.

Now combining these two together, the effect is exciting to think about.

Everyone was eager to install the bronze plowshare on the plow, then lead the deer to plow the field and see with their own eyes how effective this thing was.

“Haha, OK!”

Although the plowshare in his hand was a bit rough and simple compared to the iron plowshares of later generations, it had everything a plowshare should have.

There is no problem using it for farming.

After looking at it carefully for a while, Han Cheng laughed out loud, then reached out and patted Heiwa's shoulder, who was looking expectant, and exclaimed in sincere admiration.

Heiwa, who was already in a good mood, became even better after receiving Han Cheng's praise. He was in even better mood than after eating braised pork.

Then there was a crackling sound.

These are the remaining twelve models that were smashed.

There were thirteen plowshares in total, and one of them was defective.

The reason for the defective part was that when the second brother was pouring bronze into the mold, he did not fill the spoon full the first time, so he added a second spoon.

Copper liquid and other metal liquids solidify very quickly, and this short delay caused a fault to appear on the bronze plowshare.

Han Cheng took it in his hand, looked at it, and knocked it hard against a stone. The bronze plowshare immediately broke into two pieces.

Of course they couldn't bear to throw away the ruined bronze plowshare, so when the next pot of copper was smelted, it was put into the furnace and melted with the rest before being used again.

“Puff, puff, puff…”

In the few houses without kangs in the Qingque tribe, there were some people gathered together. The carpenter was lame and he was chopping at the bottom of the wooden plow with an axe in his hand.

After chopping for a while, he picked up the plowshare at hand and put it on the field to compare. If there was anything that didn't fit, he would remove the plowshare from it and continue to rest.

“Dangdangdang…”

After some rest, the lower end of the wooden plow finally fit well with the plowshare. Bo laid the plow on the ground with the lower end facing upwards, and then put the plowshare on it.

Later, he found a wooden board, held it on the plowshare with one hand, and with the other hand took the axe and hit the board down again and again.

The reason for putting a wooden board under it is that it is relatively soft. With it in the middle as a buffer, it can protect the bronze plowshare from being damaged by the iron axe to the greatest extent.

After more than a dozen blows of the axe, the plowshare was tightly attached to the wood.

After picking up the wooden plow and putting it away, Han Cheng held the plow handle from behind and felt it for a while, then nodded with satisfaction.

It is still crude, of course, but after being equipped with a bronze plowshare, the plow immediately looks more decent.

It is true that clothes make the man, saddles make the horse, and even the plow is decorated with metal.

Wait a moment and then make the bronze plow wall, clip it onto the plow head, and after it is fixed, the plow will look more like a real one.

After a plowshare is installed, some people can't wait to see the effect.

Without the plow wall, the soil plowed up by the plow would not flow to one side, and the plowing effect would not be very good. Han Ben originally did not want to carry the plow into the field at this time. He wanted to fix the plow wall and then use the complete plow to do experiments. But when he looked up, he saw expectant eyes all around him. After thinking about it, he nodded in agreement.

In fact, deep down in his heart, he also wanted to see the effect of the bronze plow.
