I am a Primitive Man

After Wu spoke, most of the people around agreed with Wu's words, especially the second senior brother who just swung the hammer for a while had the highest degree of agreement with Wu's words.

Now in the whole tribe, in terms of strength alone, he is the most powerful, but just now he took the hammer and smashed it hard for a long time, his arm was a little numb from the shock, but he didn't squeeze out a few drops of oil. Come on, it can be seen that there is really no oil in it.

Moreover, so much oil has been squeezed out of it, which is full of a basin, and it must have squeezed out all the oil in it.

Han Cheng glanced around, and saw that most of the people around him agreed with Wu's views. Those who didn't have a grin, could tell from their expressions that they agreed with Wu's views very much. Only Yuan didn't make a sound, and some hesitated to speak. look.

Yuan, do you think there is oil in it?

After seeing Yuan's expression, Han Cheng asked in his heart.

During these days, Han Cheng taught Yuan a lot of mathematics knowledge one after another, and he was able to master simple addition, subtraction, multiplication and division. Looking at Yuan's expression at this time, he seemed to have discovered something.

There should be oil in it.

After hearing Han Cheng's name-calling question, Yuan hesitated and said aloud.

Han Cheng ignored Wu's disbelief and astonishment, but smiled and asked Yuan again: How did you determine that there is still oil in it?

Asking like this, I secretly looked forward to it.

that is……

Yuan said that he paused here, and after opening his mouth a few times, he didn't think about how to express what he wanted to say. After scratching his head for a while, he suddenly squatted on the ground, and found a wooden stick at random. , Start writing and drawing on the ground.

Seeing such a scene, Wu, the second senior brother and others were puzzled. Didn't the Son of God ask how he knew the oil was not squeezed clean? Why are you squatting on the ground and starting to write now?

Can you write?

When Han Cheng saw such a scene, the smile on his face became stronger.

He leaned over to watch Yuan write and draw on the ground with a branch.

The first thing to be written on the ground is the nine-nine multiplication table.

According to the sequence taught by Han Cheng, the ninety-nine multiplication table can be written silently, but it has not yet reached the point where it can be used proficiently.

Therefore, when doing calculations, Yuan needs to write out the multiplication table first, and then look at the multiplication table to perform multiplication and division operations.

After writing out the multiplication table, she started to draw the division symbols with branches on the ground, and then divided by thirty-five by five, and compared with the ninety-nine multiplication table, she got the result of seven.

Then divide five by three hundred and fifty, and after some calculations, seventy is obtained.

The result of this calculation is correct, but it cannot solve the current problem.

Han Cheng could see the problem at a glance, but he didn't say anything. Instead, he stood there and continued to count circles like a first- and second-grade elementary school student.

After some calculations, Yuan wrote down the last subtraction formula. With the help of his counting fingers, after some calculations, he subtracted thirty-five from seventy and got thirty-five.

Son of God, there is still so much oil in it that hasn't been squeezed out.

Yuan pointed at the bottles containing tung oil and said aloud.

Before making the calculation, Yuan vaguely felt that the oil in it hadn't been squeezed out, but after listening to Shenzi's question, this idea became more convinced.

However, she is still not proficient in using addition, subtraction, multiplication and division, and she can't tell the problem in one mouthful, so she just squatted on the ground and calculated it for a long time.

Wu, the second senior brother and the others looked at the two oil jars in the direction of the round fingers, with expressions of disbelief on their faces.

They could all see very clearly that this time a large pot of oil was squeezed out, weighing as much as thirty-five catties, and it was all stored in these two jars.

And the second senior brother who was the strongest just now smashed it hard with a bronze hammer, but a few drops of oil did not come out,

Under such circumstances, Yuan actually said that there was still thirty-five oils in the simple oil press that hadn't been squeezed out, of course they didn't believe it.

how can that be? !

Son of God, is there really so much oil that hasn't been squeezed out?

Wu scratched his thinning hair and said aloud, with a hint of bewilderment.

He didn't believe it at first, but seeing Yuan would say that there was oil in it, Wu also became a little unsure.

After nearly a year of living together, as Wu got to know Yuan better and better, he knew that Yuan was a very smart woman.

Although what she said at this time did not sound like the truth at all, Wu still murmured in his heart.

Especially when Yuan was squatting there just now, holding a branch on the ground, writing, counting, and counting fingers, and he was still muttering words, which looked very plausible and bluffing.

When Wu asked this question, the rest of the people, including Yuan who was a little nervous, all looked at Han Cheng in unison.

Han Cheng shook his head with a smile and said, There's not that much oil.

As soon as this remark came out, Wu, the second senior brother, and the others immediately breathed a sigh of relief, especially the second senior brother, even opened his mouth, just saying, his arm was numb from the shock just now, and he needed all his strength. It's over, how can so much oil not be squeezed out under such conditions?

There was a tangled and puzzled expression on the round face. According to the calculation method taught to her by Shenzi, there was still thirty-five catties of oil that had not been squeezed out. What did Shenzi say right now?

It's not as much as the thirty-five catties that Yuan said, but it's still a lot.

Not waiting for the second senior brother and the others to be happy, Han Chenggong opened his mouth to attack everyone again. After saying this, he smiled and said to Yuan, You can do the math again.

Yuan, who was originally full of entanglements and doubts, was told by Han Cheng without too much nonsense. She squatted on the ground and began to carefully check the calculation process she had just written on the ground.

During the process of careful inspection, Yuan would write and draw with the branch in his hand from time to time, his eyes full of thoughts.

After maintaining this state for a while, Yuan's eyes suddenly lit up, and after a short pause, he took the branch as a pen and began to calculate in another place.

Different from the sluggishness during the inspection just now, Yuan's writing speed is much faster this time, and the whole calculation process seems much smoother.

Son of God, it is fifteen catties, not thirty-five catties!

After doing such calculations for a while, Yuan, who was squatting on the ground, suddenly raised his face, looked at Han Cheng and said in surprise.

Han Cheng looked at her approvingly, nodded vigorously to her, and said with a smile, Yes, it's fifteen catties!

While saying these words, Han Cheng gave Yuan a thumbs up.

The priestess of Yuan, a former semi-agricultural tribe, is indeed smarter than ordinary people. Mathematics has always been taught in the tribe. Most people in the tribe can do addition and subtraction, but when it comes to multiplication and division, then Immediately caught blind.

For the remaining people who can multiply and divide, most of them can just calculate numbers on paper, but they cannot apply it to daily life to solve practical problems.

But Yuan, a female priest from a former semi-agricultural tribe, has not been exposed to mathematics for as long as most people in the tribe. It only took more than two months, and it turned out that she was able to apply it to solve practical problems. .

Today's series of calculations, in addition to addition, subtraction, multiplication and division, actually involve some proportion issues.

Although Yuan didn't know much about this, he independently calculated the correct result.

Although the calculation was wrong the first time, it is already very rare.

After all, she has not been exposed to mathematics for a long time, and the actual application is much more difficult than simply calculating numbers.

Sure enough, mathematics is a subject for smart people, and talent really does matter a lot.

When people in the tribe do physical work, most of them are good hands, and they are not at all shy, but when it comes to various knowledge, many people feel weak in their legs and feet.

Chinese characters are better. After all, under the attraction of such well-known Qingque tribal classics such as Little Tadpole Finds Mother and Monkey Fishing for the Moon, everyone is still very interested in learning these characters.

But mathematics that is more abstract and requires memorizing many rules is really a pain in the head. Even the best stones in the tribe are still scratching their heads when it comes to mathematics. You just know the four simple arithmetic operations, and if you go deeper, you will not be able to understand and learn.

In this whole tribe, the level of stone is first-class.

Now that he found a good seed like Yuan, Han Cheng naturally couldn't let it go, and he needed to be encouraged.

This will help Yuan better immerse himself in the fascinating world of mathematics, and go further and further, laying the foundation for the future development of the tribe.

Han Cheng, who came from later generations, naturally knows the importance of mathematics, especially after the society has developed to a certain level, Han Cheng is more aware of the role that higher-level mathematics can play in the development of society.

Advanced and complex mathematical knowledge is of course not needed when shopping for vegetables, but there are many other things in this world besides grocery shopping.

Mathematics, when Han Cheng was studying at the beginning, he was really embarrassed to lose his hair, but after working, he rarely used it, but he would not deny the significance of learning mathematics because of this.

Now that Han Cheng has come to this world, naturally he will not abandon him.

The man who was hit on the head by an apple said that it was easier to pick apples by standing on the shoulders of giants.

Compared with the current tribe, Han Cheng is undoubtedly a giant. If he can leave these things behind, then future generations, based on the foundation he laid, can also stand on the ground of others from birth. It is likely to be above the end point that is impossible to reach in his whole life.

Using this as a starting point, we can always go further and make the tribe better.

Of course, these are many years later.

However, regardless of these future things, the Qingque tribe at this time also needs mathematical knowledge.

For example, statistics are made on the harvested grain and the fur in exchange.

Based on head count, how much food does the Qingque tribe need in a year? A road requires different numbers of people to build, how long does it take to harvest it?

The crops in the field can be harvested in about how many days if everyone works together...

This series of things all need to rely on mathematics to calculate in order to be aware of it.

Although there will be errors, they are much more accurate than estimates.

Not to mention the rest, if it wasn't for Han Cheng's calculations to know that the oil yield rate differed too much this time, the oil contained in the oil residue would have been wasted.

After hearing Yuan say fifteen catties, and getting Han Cheng's personal confirmation, the second senior brother and the others were suddenly a little dazed.

Although fifteen catties was not as much as the thirty-five catties that Yuan said before, it was also not a small amount.

You know, this time only thirty-five catties of oil were squeezed out, and two cans were filled.

This fifteen catties of oil can basically fill a jar!

God... Son of God, is there really so much oil?

The second senior brother looked at Han Cheng stutteringly and asked.

Han Cheng nodded and confirmed the matter again.

Seeing this, the second senior brother, who was scratching his hair, was about to smash the stakes with a bronze hammer, but was stopped by Han Cheng.

After thinking about it, Han Cheng basically wanted to understand why the oil production rate this time was so different from the last time.

This time, more tung oil fruit powder was put in, ten times more than last time.

If so many tung oil powders are stacked together, the elasticity will increase and it will not be easy to smash them through.

To sum it up in one sentence, it is too much to chew.

The second senior brother who was stopped by Han Cheng was scratching his hair there, and Wu He, Yuan Yuan who had just calculated that there were still fifteen catties of oil in it, and more people were scratching his hair with him.

The strength of the second senior brother is the strongest among all the people in the tribe. This is recognized by everyone. Now that the Son of God stops the second senior brother and prevents the second senior brother from swinging the hammer, how can we get out the remaining oil?

Of course, there was a reason why Han Cheng blocked the second senior brother. The second senior brother's strength was no longer able to squeeze out the remaining oil. If he could squeeze it out, he had already succeeded.

Even if he held the hammer again and smashed violently, it would be a waste of effort.

God, what should we do now?

A group of people looked at Han Cheng with puzzled eyes. Even the most powerful second senior brother couldn't do anything about the remaining tung oil. They really couldn't think about it.

I have a way to squeeze them out!

Human beings have limited abilities. They cannot swim as well as fish, cannot run to catch up with horses, and cannot fly in the air like birds.

However, because people have a well-developed brain, they can create various tools to solve various problems they face.

With the help of ingenuity and various tools, one can go to the sky and enter the earth, and can dive into the deep sea...

When the strength of the human body reaches its upper limit, then tools are needed.

Han Cheng made a very simple tool this time, it was a ram, just like the ones used to strike bells in temples.

However, the section of wood used as a bumper is larger, longer, and heavier than that of ordinary temples, and the impact force is correspondingly greater.

Boom!

Boom!

Han Cheng pulled the rope tied to the hammer with his hands, pulled the hammer back and raised it, and then followed the force of the hammer back and pushed back hard.

Under the control of Han Cheng, the ramming hammer with great power, with its own weight and the inertia of swinging in the air, coupled with the force Han Cheng put on it, slammed into the wooden hammer hard. on the pile.

Surrounded by a circle of curious people.

Everyone chooses to believe in the tool made by the Son of God, but there is some disbelief in this belief.

Because the second senior brother, who is the strongest in the tribe, couldn't hit it with a bronze hammer, and Shenzi, who is not good at strength now, said that he would use such a tool to knock down the wooden pile and squeeze out the oil.

Even though they were sincerely convinced of the Son of God, under such circumstances, there was still some unbelief contained in their conviction.

However, when the ram made of rough wood hit the stake under Han Cheng's control, the eyes of the onlookers all widened. , all turned into powder, transformed into surprise and disbelief!

Under this collision, the second senior brother, who was the strongest in the tribe, was smashed into a section of the stake that could not be smashed down with a bronze hammer, at a speed visible to the naked eye.

Oil! Oil! Oil is coming out again!

When many people were still surprised by such a scene and did not come to their senses, someone pointed to the bottom of the simple oil press and shouted excitedly.

After hearing the words, everyone went to look at it, and saw that the simple oil press that had been determined to have no oil existed before. After Han Cheng pulled the ram and hit it again and again, oil began to drip, and it quickly disappeared from one drop to the next. The drops turned into a few thin lines...

It turns out that there is really so much oil in it, and it turns out that hanging a piece of wood horizontally has such a big impact!

Come on, bump into me!

After Han Cheng held the ram for a while alone, he said to the second senior brother standing beside him.

Under Han Cheng's signal, the second senior brother stood on the other side of the ram, and then worked hard together with Han Cheng, one left and one right, pulling the ram back and pushing it forward.

With the addition of the second senior brother, a man of great strength, the advantage of the ram was brought into full play.

With the impact of the ram again and again, the stake was smashed into it little by little, and more and more tung oil was squeezed out from it.

Son of God, this idea is really good!

Looking at the tung oil that weighed more than seventeen catties, the second senior brother said excitedly.

Using this method, not only can the tung oil be squeezed clean, but also very labor-saving.

Even though the second senior brother has a lot of strength, when he can save his strength, he doesn't want to use too much strength, and make himself as tired as the lucky general who sticks out his tongue to dissipate heat...

Because of the successful manufacture of the oil press, and because Han Cheng made such a labor-saving and efficient ram, the Qingque tribe seemed very happy.

Those lively and active minors always like to come here when they have nothing to do, and they always want to come here to play with the ram when they have free time.

Han Cheng was also very happy. On the one hand, he took the people from the Qingque tribe and made the oil press from scratch. From now on, there will be another machine in the tribe. On the other hand, That is, Yuan is really as talented in mathematics as he imagined at the beginning.

This is the benefit of smart people. In many things that require brains, the progress is always very fast.

After the successful large-scale oil extraction this time, Han Cheng did not let people continue to extract oil. The oil extracted now is enough, and the remaining tung oil fruits can wait until winter for oil extraction. After all, at that time , people in the tribe are more idle.

After this kind of busy work, the autumn is even more remnant, and the grass around the tribe has turned dark green. When we wake up in the morning, the dew with chills sticks to the grass leaves, and it looks like a vast expanse of white.

When people walk by here, dewdrops roll down while the grass leaves are shaking, sticking to the feet, making them a little cold.

The mountains and forests in the distance have also become colorful. Although it has not reached the point where the mountains are red and the forests are completely dyed, it is almost there.

Before he knew it, Qingque's ten-year late autumn had arrived.

In the courtyard, Han Cheng, wearing leather gloves, directly dipped a pair of rattan armor into a clay pot filled with tung oil. After turning it back and forth a few times, the entire rattan armor was covered with tung oil.

Holding the rattan armor in his hand, he waited for a while on top of the pottery basin until no more oil dripped from it. Han Cheng then hung the rattan armor on a shelf not far away.

A dozen pairs of rattan armor soaked in tung oil have already been hung on this shelf, and now under the sunlight of late autumn, with some light, it looks very beautiful.

Boom, boom, boom...

Little Pea, who was carried back and forth in the tribe by the pandas, held a rattle in her hand, shaking her back and forth, grinning silly, happy like a fool.

The rattle in Little Pea's hand also seemed to have a layer of light, which was much brighter compared to the dim color before.

This is also due to several layers of tung oil.

However, the rattle was not soaked in a tung oil basin, but was wiped out with tung oil on the unsuccessful silk that Bai Xuemei wove with silk, so that it would not leave any traces on it, and it looked more beautiful.

Tuk Tuk Tuk...

This is the sound of the crutch point on the stone road.

As the sound approached from far away, a witch with a cane in one hand and a handful of wild fruits in the other appeared in the field of vision.

It's just that Wu's walking posture at this time is very awkward. Every time he walks forward, his body will involuntarily lean towards the side of the crutch, and the crutch sticks out a lot, and the frequency is also high.

It didn't look like he was walking, but he was specifically showing off his crutches.

In fact, Han Cheng had asked Lame and Wu to make this crutch a long time ago, but Wu felt that wearing a cane would make him look old and could not show the strength of his body, so he left it there and never used it.

However, ever since Han Cheng soaked the crutch in mint juice for a few days, dried it, and wiped it several times with an unsuccessful silk cloth dipped in tung oil, Wu could not walk without this crutch. carry everywhere...
