As early as the time of the Three Ancient Emperors, the human race had already been able to use stone sickles and clam sickles. These two things were the prototypes of saws. Some people believe that the person who invented the clam sickle should be the Chao family.
Otherwise, why did the human race not have the skills to build houses before the Chao clan, but after the Chao clan, the human race suddenly built tall wooden houses. Stone axes alone cannot solve the problem of board accuracy.
Yan Zai took aim at this newly created thing, her palms were red, and her blood boiled for a long time because she tried to compress the small-scale flames.
The Iron Ox squatted here, and Ruzai hung his brass ax high on the beam, with the ax handle downward. The Iron Ox just squatted there motionless. This was probably the same as fishing a donkey with a carrot.
The reason why Yu Zai didn't let Tieniu go was because this simple but easy-to-use thing needed Tieniu's help.
Of course, it cannot be that the mop is stained with manure. The last time I fed a large piece of copper to an iron bull, I only got thumb-sized pieces of iron. The iron was very hard, but it had no properties, and it was obviously not deified. Influence.
Because the original copper was inferior, inferior to the divine copper, and after being eaten and pulled by the iron ox, the iron that came out was very strong, but it did not possess the power of deification.
But for Yu Zai, this is fine, as long as it is sturdy, don't use it, it will be fun if a ball of fire breaks out on it.
"What's this?"
Since Dayi came to the Chifang clan, he has taken on the task of raising chickens and walks them regularly every day. Now the chickens in the chicken farm have begun to grow up, and the new flock of chickens makes him unable to leave for the time being.
And Uncle Xi and Chi Songzi have now become Suzai's new followers.
"It's a brand new version of Clam Scythe."
Yu Zai made some gestures and gave it a try. He took a piece of wood, held the upper part of the wood with his palms, pressed the wood tightly with his feet, and then pointed a jagged iron bar at the piece of wood. .
Click buzz——
The iron teeth carved deep carvings into the wood!
"It's 'Saw'!"
It worked.
"Iron saws cannot be mass-produced. The main reason is that the iron ox eats so much and pulls out too little..."
However, there were also copper saws during the Warring States Period. The metal strips of copper saws were much thicker than the thin strips of later iron saws.
The hardness is not enough, so the volume is needed.
"This is very useful."
Uncle Xi took what Yu Zai handed over and sawed hard with the piece of wood.
Chi Songzi looked on.
This thing is one of the basic tools necessary for woodworking construction and production. It tastes better when used with a hammer and a chisel. It is no exaggeration to say that a powerful carpenter during the Warring States Period could use miraculous skills with only these three things. Various strange instruments were produced, among which the representative figures were Mozi and Gongshu Ban.
The so-called mortise and tenon method actually existed at this time, so among the trolleys, there were several experimental models that were also used above.
Yu Zai learned about this from her former teammate, of course the archaeologist who was knowledgeable and liked to brag.
[The earliest appearance of mortise and tenon structures on this land can be traced back to the Hemudu period... In the Hemudu ruins, a large number of dry-type mortise and tenon structures were discovered. For example, fire-convex square tenons, double-layer square tenons, and dovetail tenons... The Hemudu site discovered in 1973 contains a large number of wooden building remains that transcend the times, which are consistent with the 'sage's wooden structure' mentioned in ancient books. It is completely consistent, so some people speculate that the Hemudu people are probably the people of the Chao clan...]
The people of Hemudu are seven thousand years away from later generations, and two thousand eight hundred years away from the present era!
It was about the period from the Wulong clan to the Three Taikoo Emperors!
"So, the Chao family is the ancestor of carpentry..."
The Youchao clan was the first of the five ancient clans. According to the Book of the Three Emperors, he built wood as a nest and used leaves as clothes.
The square thing that Uncle Xi saw was the so-called rice bucket.
But it's not useful yet.
Uncle Xi knew that this thing was just a tool for carrying things. It was essentially the same as a clay pot, a wooden barrel, a bamboo cup, or a basket. It was just smaller, and the wood was not easily damaged, so it was strong and durable.
There are also "shengzi", "hezi" and "spoon" on the side of the rice bucket, but spoons are not a new thing.
The shape is a square platform with a larger top and a smaller bottom. It is an instrument made of four trapezoids and a square wooden board, and then joined together with mortises and tenons. It is smaller than a bucket.
"Ten liters equals one bucket."
Yu Zai just asked Yu Liang to make this thing casually, saying that when the harvest came, everyone would be able to share the food. Uncle Xi knew that there was a lot of this stuff, and it didn't have any technical content. After reading it, he felt that he should go back. Get one.
"The key point of this thing is to unify the measurement."
Uncle Xi is very familiar with spoons.
Regardless of whether the new measurement unit is formulated, whether it is related to weight or length, of course, these are all changes to the existing "Zhang", "Shi", "Jun", "嬬", "仞", Units such as "She" and "Xun" are more detailed. Of course, the Central Plains also has its own niche names for these detailed units. At first, Emperor Fangxun wanted to promote new small units, but because the people said that this was too It was troublesome and gave me a headache, so I gave up temporarily.
Uncle Xi picked up another object and stretched it out, just like the lotus leaf he was holding when he came.
Uncle Xi played with it in a very novel way and called out twice.
"Is this an improved version?"
The 簦 is the oldest umbrella. It was originally just a bamboo hat with a handle, so it could not be folded or put away. Uncle Xi himself had a lot of these things, because it was rainy in the south, so out of boredom, Uncle Xi started playing the game of collecting "簦", and his obsession was probably similar to that of a stamp collector.
The most powerful "簦" is probably the one owned by Qin Shihuang. I don't know if Qin Shihuang's sword was stimulated by an assassin who didn't wear pants, or someone who was waiting hard in Bolangsha. Such an infatuating thrill... The umbrella head and paratrooper of that thing can be separated. Although it cannot be folded, after the umbrella head and umbrella handle are separated, the paratrooper becomes a spear and the umbrella head becomes a shield. .....
"This is good, this is good, can I buy one?"
Uncle Xi knew that his status was that of a guest. He was only staying temporarily. He could not ask for anything from others and had to exchange it for equal value. However, Yu Zai waved his hand and said, "Yang Ji, you are too foreign. We are all one family." , if you want this thing, just ask, anyway, there will be more later.”
"But I want to give this to Yuliang first and let him take notes."
Yu Zai made this umbrella. The reason why the umbrella surface can be folded is because it is actually made of the skin of an old turtle.
After the death of the old turtle, purple materials exploded all over the ground, including turtle shell, turtle skin, turtle tail, turtle tail, turtle viscera... In short, there are a bunch of useful ones, and there are also useless ones, but in general, the useless ones can be fed to the turtles. Long, Yuzai even prepared some meat marinated with salt and earth, and planned to go to Daze to have a heart-to-heart talk with the old turtle.
