I am a primitive

After figuring things out and deciding on a strategy, Han Chengcheng went to find Hei Wa.

After searching around, he couldn't find it. Later, he heard that it was in the cave, so Han Chengcheng walked towards the cave.

A fire was lit in the cave of the Qingque Tribe, and around the fire, there were half a circle of pottery molds, big and small.

Hei Wa was holding the clay with frozen hands not far away, and kept moving her fingers. After a while, she would press something on the clay with another object, then picked up the bamboo knife, and rested for a while, Do it very seriously.

What Heiwa is doing now is the example of a plowshare that he has struggled with for a long time.

After a long period of thinking—experiment—thinking—and experimenting, he now finally has a way to solve this problem.

Fortunately, before the heavy snow completely melted, the matter of the plowshare model was figured out, otherwise, the spring plowing in the tribe would be delayed.

Thinking of this, Heiwa was very happy, not only because he had made the mold of the plowshare before the spring plowing, but also because he came up with this method himself.

Through her unremitting efforts, she overcame the headaches, and Heiwa was fascinated by the feeling of comfort at the moment of overcoming the difficulties.

Hugging with Zhuang and humming a little song is not as refreshing as this feeling.

Moreover, what he solved this time is not just the plowshare. With the plowshare model, he can make more models of utensils by promoting it to other places.

Copper basins, copper vases and other things, as long as he is given more time, he can get them out.

At this time, Hei Wa seemed to have overcome the ups and downs and saw the people with a smooth road ahead, and her heart was full of enthusiasm.

Driven by the desire to make the mold of the plowshare as soon as possible so as not to delay the spring plowing, and to fiddle with other utensils, Heiwa is now extremely enthusiastic about making the mold.

Now that the weather is only slightly warmer, he can't wait to start.

The reason why I choose to do these things in the cave is because the cave is more spacious than the room, so I can let my hands and feet loose, and the second is that there is no wind and the temperature is higher compared with the outside, and Good clay is not easy to freeze.

Make a mold in your hand, carefully put it on the edge of the fire, and evaporate the water inside by roasting.

After doing this, turn over the ones that were originally placed around the fire and continue to roast.

Some of the first ones were completely baked, so Hei Wa put them into the fire and burned them directly.

Through the previous casting of bronze ware, Hei Wa found that the mold does not need to be fired particularly well, and it does not need to be put into the kiln. It only needs to be burned in the fire for half a day, and then it can be used after being taken out. The effect is not inferior to that of pottery.

After doing this, Hei Wa squatted beside the fire, stretched out her hand and used the fire to roast her frozen palms.

At this time, the weather has just warmed up, and it is not a good season for playing in the mud. The cold mud is very cold to the touch.

"How's it going?"

Han Cheng, who stood not far away and watched for a long time, smiled and said, Hei Wa, who was immersed in his own world, was so frightened that his body shook...

-------------Chapter Dividing Line---------------

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

At the quarry, the wind whirled and turned, pouring gusts of wind into the boiler through the clay pot, blowing the charcoal fire, making it burn more vigorously.

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

"Open the furnace!"

The second senior brother, who had been transformed from a blacksmith into a coppersmith, yelled, and the idlers around him moved to the side, making room for an open space, so as not to be accidentally injured by the high-temperature copper water.

Seeing everyone get out of the way, the second senior brother, who had successfully lost weight, scooped up the viscous copper juice with a special earthenware spoon, put it on the mud form where only a small hole was left, tilted it, and put it The copper juice is poured in along the hole.

The strong second senior brother had a steady hand, and a spoonful of copper juice was poured in along the hole, rarely spilled, which was much better than that of Han Cheng at the beginning.

Hei Wa's eyes widened, and her hands unconsciously clenched the animal skin she was wearing.

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

The reason why the remaining one will not be filled is because the copper juice in the furnace is not enough to fill a clay pan, if it is poured in, a clay pan will be wasted in vain.

It is not easy to make such a clay fan, so naturally, one less waste is one less waste.

However, the remaining copper juice did not allow it to cool down like this, but used them to pour out two small copper knives.

"click~"

After this combination, only one hole is left to pour bronze juice inside. Compared with a single mold, it is not only troublesome to manufacture, but basically cannot be reused.

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

It hurts to break the mold that has been made so hard, but Heiwa didn't have much soft hands when she picked it up. When she picked it up and threw it on the ground, the outer layer of the bronze plowshare that was poured first collapsed. up.

A piece of yellow light was revealed among the mud flakes flying randomly.

Hei Wa quickly found a small crowbar made of bronze, and poked off the pieces of mud sticking to it that refused to leave, and a plowshare that was a circle larger than the palm of an ordinary person appeared in his hand.

The plowshares are shiny yellow, which is really beautiful, and it doesn't look like there are many flaws.

"Son of God!"

After looking at it for a while, Hei Wa held the plowshare that he had finally got out, ran to Han Cheng excitedly, and showed it to Han Cheng as if offering a treasure, cheerfully like a child.

With a smile on his face, Han Cheng took the long and hard-won plowshare from Hei Wa's hand, held it in his hand and watched it carefully.

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

And in terms of size and weight, they couldn't keep up with those iron plowshares he saw in later generations.

The reason why the plowshares are cast so small is that on the one hand, the bronze is relatively brittle, and if the cast is too large, it is easy to be damaged when plowing the land.

On the other hand, the deer in the tribe are weak, and the plowshares are too big, so the deer can't pull them.

When Han Cheng was looking at the plowshares, Wu and others here also gathered here. They have all experienced the ease of using deer to plow the land and bronze wares.

Combining the two now, the effect is exciting to think about.

Everyone can't wait to put this bronze plowshare on the plow now, and then lead the deer to plow the field and see for themselves how effective this thing is.

"OK!"

Compared with the iron plowshares of later generations, the plowshare in the hand is rough and simple, but it lacks everything a plowshare should have.

There is no problem in using it to cultivate land.

After looking carefully for a while, Han Cheng laughed out loud, then stretched out his hand and patted Hei Wa's shoulder with an expectant face, admiring him sincerely.

Hei Wa, who was already in a good mood, became even better after being praised by Han Cheng, even more beautiful than eating braised pork.

Then there was a crackling sound.
