With the change in the vegetable garden comes harvest and joy.
The stone grinding that Xu Chen has always been most concerned about has gradually taken shape.
Under the constant hammering of two stonemasons every day, the two stone mills slowly took shape.
Time has entered March, and Mother's Day is getting closer and closer.
The construction of the two stone mills was finally completed.
In order to ensure that there would be no mistakes in the stone milling this time, Xu Chen spent almost the entire last few days in the pergola, carefully observing and instructing the two stonemasons.
This pair of stone mills has a diameter of two feet and weighs more than three hundred kilograms together.
The upper fan is about 20 centimeters thick, with grinding holes on the top and bottom, and square holes on the side for mounting the grinding arms.
The lower fan is about 40 centimeters thick, with a grinding hole in the middle for installing a fixing pin, and a stone skirt groove around it for receiving flour and water slurry.
Although the stone mill has a simple structure, it is the most complex and sophisticated stone tool made by a group of stonemasons.
The most difficult part is not the shape, but how to create a flat seam on the contact surface.
In order to grind the grain thoroughly, it is necessary to ensure that the fan-shaped grooves inside are of uniform depth and thickness.
If we only relied on the rough technology of making stone mortars and grooves in the past, this stone grinding would definitely not be easy to succeed.
However, with the repeated practice and progress of a large number of stone benches, stone bricks and even the four stone beasts on the God's Eye Altar, the two stonemasons finally succeeded in advancing. Although it took more than twenty days and the progress was very slow, they finally succeeded in Xu.
Under Chen's careful supervision and guidance, he worked slowly and carefully to complete the construction of the first stone mill in human history.
They didn't know what the stone mill could do, let alone why Xu Chen built such a strange thing, and of course they didn't know the practical significance of this stone mill to human civilization.
All they knew was that they had finally completed the task assigned by Xu Chen.
They are just Xu Chen's tools. They work according to the tasks assigned by Xu Chen every day. As long as Xu Chen is happy, they can work until the end of time and will not consider self-creation at all.
Just like how they made stone knives and axes before, because ancestors have been hammering and polishing them like this for generations, change and innovation are very difficult. It requires not only wisdom, but also the guidance of the gods. Xu Chen is the magical leader blessed by the gods, leading the tribe to continuously create the same
Another magical and mysterious item quickly developed and grew into the most powerful tribe.
The two processed stone mills were carried under the built pergola by a group of strong hunters. According to Xu Chen's instructions, the lower millstones were firmly placed and wooden wedges were placed on the surrounding mill frames to secure them.
Xu Chen took matters into his own hands and wrapped a half-foot-long copper pillar that had just been cast tightly with linen cloth and nailed it into the hole in the center of the millstone. Then he gently knocked a hollow copper ring into the hole in the center of the upper millstone.
In the hole, the two millstones are then put together, and the copper ring in the center is placed on the copper pillar.
The upper and lower millstones are put together, and they look perfectly matched. In terms of appearance and shape, they are almost the same as the stone mills that were common in rural areas in later generations.
If there is any difference, it is that the stonemason's workmanship is a little rough, and the appearance is not very smooth.
But it is indeed a real stone mill, and it already has the normal functions that a stone mill should have.
And Xu Chen also believed that as long as the stone mill was turned, the grain would be ground into fine powder.
The whole clan, men, women, old and young, gathered around the mill awning, discussing loudly and lively.
This strange combination of stone tools is the most mysterious and confusing thing they have ever seen.
Because from beginning to end, Xu Chen never explained the function and use of this thing.
A group of older women such as Mom, Bahe, and Amu stood at the front surrounded by the little witch, watching Xu Chen instructing several masons and carpenters to work, their eyes unblinking and full of anticipation.
When Xu Chen finally put a push rod hanging from the roof of the pergola into the grinding arm of the upper stone mill, the entire stone mill was completely assembled.
"Okay, it's finally installed!"
Xu Chen wiped the beads of sweat rolling down his forehead.
"Is this the end?"
The onlookers looked at each other in amazement as they looked at this strange and complicated thing that was finally assembled.
"That's right. Once it's done, you can use it to grind the flour below!"
Xu Chen kicked the little wolf cub that was constantly spinning around the grinding frame to the side.
"Moga grinding noodles?"
"What is grinding noodles?"
Many people were confused and had doubts and discussions.
"Ye, go get a pot of wheat, and by the way, I also need a wooden spoon!"
Xu Chen wiped his sweat and ordered, and Ye immediately turned around and ran to the warehouse where the grain was stored. Soon he came over with a pottery basin filled with oats and a wooden spoon that was more than a foot long.
But after everything was ready, Xu Chen was a little dumbfounded again.
There were hundreds of men, women, and children at the scene, as well as dozens of powerful and brutal men, but none of them knew how to push a grinder. Even he was the only one who knew how to feed a grinder.
Seeing Xu Chen staring at the stone mill in a daze, a group of people didn't know what to say. The little witch stepped forward and pulled Xu Chen's arm and asked softly: "What's wrong?"
Xu Chen smiled bitterly and said: "It takes two people to grind noodles, but I am the only one who can do it."
The little witch was also dumbfounded. She stayed there for a long time and said nervously: "I, I will help you!"
Xu Chen looked at the little witch, then at the stone mill, then at the earthen basin, and finally nodded helplessly and said: "Okay, give it a try, it's a bit dangerous, you must be careful!"
Next, Xu Chen called the little witch to the stone mill and began to teach her how to feed the mill.
The action of feeding and grinding is not complicated. People who are familiar with it can do it well with their eyes closed, but those who are not familiar with it can easily cause accidents.
Feeding the grinding wheel is the same as pushing the grinding wheel. It requires a rhythm and speed. Because the stone grinding wheel needs to use force after being pushed, the rotation speed is generally very fast. The person who feeds the grinding wheel must also have good eyesight and quick hands, so that the grinding arm can turn at the right time every time.
When pouring the grain into the grinding eye, you must also take your hand back as soon as possible, otherwise it will be hit by the grinding arm or push rod that turns back quickly, and the grain may even be knocked to the ground.
These are things Xu Chen experienced when he was a child.
Because in rural areas, it is a common housework for children to help adults feed and grind, and one stop lasts for half an hour or even more than an hour. For children who like activities, it is tantamount to torture in life.
However, this profound memory of being tortured as a child has also become a sophisticated skill for him to show off after time travel.
Xu Chen carefully explained to the little witch, and everyone gathered around to listen attentively.
After repeating the demonstration several times to ensure that the little witch understood it, Xu Chen casually called a man over, pointed at the grinding arm and gave some instructions, asking him to help him push down and use force when he started grinding.
Because there were so many people in the tribe, this stone mill was also made very large. The two-foot-diameter millstone alone weighed hundreds of kilograms. It was not easy to push such a heavy mill.
Originally, Xu Chen also thought about making a smaller one, but considering the height, physique and strength of the savages, he felt that there would be no problem in making it bigger. After all, they are a group of powerful savages. They can't do anything else except one.
With brute force, you can build it hard.
After Xu Chen finished his instructions, he walked to the front of the stone mill, adjusted his body position with his legs in front and back, grabbed the handles on both sides of the push rod with both hands, pushed forward with both arms, and said to the man he had just told: "Push
one time!"
The man quickly helped to pull the grinding arm. Xu Chen felt a lightness in his hands and quickly used the force to push the grinding rod forward. The stone grinding wheel spun forward and reached its furthest point in an instant. At this time, with the acceleration of the stone grinding rotation,
He quickly leaned back and pulled the grinding rod, so that the stone grinder completed a circle of rotation and returned to its original position.
"Wow!!"
Seeing the stone mill turning like this, the men, women and children who were watching all let out violent exclamations and commotion.
After the stone grinding was completed, Xu Chen pushed the grinding arm to rotate twice with his hand. Everyone knew that the stone grinding wheel could rotate, but they did not know that it was actually used in this way.
And I don’t know what the two complex stone tools that Xu Chen was doing after spending more than half a month guiding and supervising them every day were built.
"Hey Mo!"
Seeing the moment when Grinding Arms passed in front of the little witch again, Xu Chen quickly reminded her loudly.
The little witch was holding a pottery basin in her arms with a face full of surprise. She was a little panicked when she heard the shouting, and quickly scooped up half a spoonful of wheat with a wooden spoon. However, she was frightened when she saw the grinding arm turning around with a clatter and then quickly turning around.
After taking two steps back, the wheat almost fell to the ground.
"Don't be afraid, just pour the wheat in according to the method I just taught!"
Xu Chen kept pushing the stone mill with his hands and making another idling circle while loudly reminding him.
The stone mill is very heavy, and it is newly milled. The intertwined fan-shaped grooves in it bite and rub against each other, and the resistance is extremely high. Fortunately, Xu Chen's body has grown very fast in the past two years, and he has grown into a powerful and wild young man.
, otherwise he would never be able to push this mill two or three years ago.
Even if he can push it now, it is actually very difficult.
Now I have only pushed twice, and my arms feel a little weak.
The stone mill quickly turned to the third circle. Under Xu Chen's loud reminder and comfort, the little witch calmed down quickly. After the grinding arm passed, she quickly stepped forward and poured half a spoonful of wheat into the grinding eye.
However, because the speed was too slow and I didn't have a good grasp of the rhythm, I was so scared that I quickly took my hand back before I finished pouring.
The rapidly rotating stone mill turned around with a clatter, its arm barely grazing the wooden spoon in the little witch's hand, knocking the unfinished wheat inside and scattering it to the floor.
"Wow!"
The crowd suddenly burst into even more violent exclamations. Many people turned pale and hurriedly stepped back. An older woman quickly pulled the little witch back.
Xu Chen stopped the stone mill and hurried forward to ask. He found that the little witch was not injured, but was just a little frightened. So he breathed a sigh of relief and comforted him: "Don't be afraid. Apart from the fact that the stone mill spins faster, there is actually no danger. You must pay attention."
With strong eyesight and quick hands, we can’t hesitate at all. Let’s try again!”
"good!"
The little witch was a little frightened, but under Xu Chen's encouraging eyes she mustered up the courage and scooped half a spoonful of wheat again to get ready.
This time, in order to allow the little witch to complete the feeding and grinding accurately, Xu Chen pushed slightly slower, but it was obviously more difficult.
Under the gaze of hundreds of pairs of eyes, and finally reminded loudly by Xu Chen, the little witch quickly poured half a spoonful of wheat into her eyes.
Although part of it was still piled outside, the hand was quickly retracted and the arm was narrowly avoided.
