After Wu opened his mouth, most of the people around him expressed their agreement with what Wu said, especially the second brother who had just swung the hammer for a while, who agreed with Wu's words the most.
Now in the whole tribe, he is the strongest person in terms of strength. Just now, he personally swung the hammer and smashed it hard for a long time. His arms were numb from the shock, but he didn't squeeze out a few drops of oil. It can be seen that there is really no oil in it.
Moreover, so much oil has been squeezed out of it, enough to fill an entire basin. All the oil must have been squeezed dry.
Han Cheng glanced around and saw that most people agreed with Wu's opinion. From the expressions of those who did not groan, it could be seen that they very much agreed with Wu's opinion. Only Yuan did not say a word, as if he wanted to say something but hesitated.
"Yuan, do you think there is still oil in here?"
When Han Cheng saw Yuan's expression, he suddenly asked.
During this period of time, Han Cheng has taught Yuan a lot of mathematical knowledge, and he has been able to master simple addition, subtraction, multiplication and division. Looking at Yuan's expression at this time, it seems that he has made some discoveries.
“There should still be oil in it.”
After hearing Han Cheng call on her to ask a question, Yuan hesitated for a moment before speaking out loud.
Han Cheng ignored Wu and the others' disbelief and surprise, and smiled and asked Yuan Dao again: "How did you determine that there was still oil in it?"
I asked this with a hint of anticipation in my heart.
"that is……"
Yuan paused here, opened his mouth several times, but still couldn't figure out how to express what he wanted to say. After scratching his head for a while, he suddenly squatted on the ground, found a wooden stick, and began to write and draw on the ground.
This scene made Wu, Second Senior Brother and the others puzzled. Didn't the Son of God ask how he knew the oil was not squeezed clean? Why was he squatting on the ground and writing now?
Can you write?
When Han Cheng saw this scene, the smile on his face became even more intense.
He leaned over to watch Yuan writing and drawing on the ground with a branch.
The first thing that Yuan wrote on the ground was the multiplication table.
I can recite the multiplication table in the order taught by Han Cheng, but I am not yet proficient in it.
So when doing calculations, Yuan needs to write out the multiplication table first, and then perform multiplication and division operations according to the multiplication table.
After writing out the multiplication table, she began to use a branch to draw division symbols on the ground. Then she divided thirty-five by five, and compared it with the multiplication table to get the result of seven.
Then I divided three hundred and fifty by five, and after some calculations, I got seventy.
The result of this calculation is correct, but it cannot solve the current problem.
Han Cheng saw the problem at a glance, but did not say anything. Instead, he stood there and continued to calculate the circle like a first or second grade student.
After some calculations, Yuan wrote out the last subtraction equation. With the help of counting on his fingers, he did some more calculations and subtracted thirty-five from seventy, getting thirty-five.
"Son of God, there is still so much oil that has not been squeezed out."
Yuan pointed at the bottles of tung oil and spoke.
Before making the calculations, Yuan had a vague feeling that the oil inside had not been fully squeezed out. Later, after hearing the Son of God's question, this idea became more certain.
However, she was not proficient in addition, subtraction, multiplication and division, and could not immediately explain the problem, so she squatted on the ground and calculated for a long time.
Wu, Second Senior Brother and the others looked in the direction of Yuan's finger, towards the two oil jars, and each of them had an expression of disbelief on their face.
They all saw it very clearly. This time, a large basin of oil was squeezed out, as much as 35 kilograms, all of which were put into these two jars.
Moreover, the second brother who had the greatest strength just now picked up the bronze hammer and smashed it hard, but in the end not a few drops of oil came out. Under such circumstances, Yuan actually said that there were still 35% of oil in this simple oil press that had not been squeezed out. Of course, they didn't believe it.
How is this possible? !
"Son of God, is there really so much oil that has not been squeezed out?"
Wu scratched his sparse hair and spoke with a puzzled look.
He didn't believe it at first, but when he heard Yuan say that there was still oil in it, Wu became a little unsure.
After living together for nearly a year, as Wu got to know Yuan better and better, he realized that Yuan was a very smart woman.
Although what she said at this time did not sound true at all, Wu still had doubts in his heart.
Especially just now, when Yuan was squatting there, holding a branch and writing, calculating, and counting his fingers on the ground, muttering to himself, it looked very realistic and quite intimidating.
When Wu asked this, everyone else, including Yuan who was feeling a little nervous, turned their eyes to Han Cheng.
Han Cheng smiled and shook his head, "There's not that much oil."
As soon as these words came out, Wu and Second Senior Brother immediately breathed a sigh of relief, especially Second Senior Brother, who smiled happily and said, his arms were numb from the shock just now, and he had almost used up all his strength, so how could there be so much oil that had not been squeezed out under such circumstances?
There was a look of confusion and doubt on her round face. According to the calculation method given to her by Professor Shen Zi, there were still 35 kilograms of oil that had not been squeezed out. Why did Shen Zi say there was none now?
"Not as much as the thirty-five kilograms Yuan said, but it's not a small amount either."
Before the second brother and the others could be happy for long, Han Cheng once again attacked them. After saying this, he smiled and said to Yuan: "You try to calculate it again."
Yuan, who was originally full of confusion and doubts, didn't say any more nonsense after hearing what Han Cheng said. She just squatted on the ground and began to carefully check the calculation process she had just written on the ground.
During the careful inspection process, Yuan would occasionally use the branch in his hand to write and draw, his eyes full of thoughtfulness.
After maintaining this state for a long time, Yuan's eyes suddenly lit up. After pausing for a moment, he took the branch as a pen and started calculating in another place.
Different from the slow pace of the previous check, Yuan's speed this time was much faster, and the whole calculation process seemed much smoother.
"Son of God, it's fifteen pounds, not thirty-five pounds!"
After calculating like this for a while, Yuan, who was squatting on the ground, suddenly raised his face and looked at Han Cheng with surprise and said.
Han Cheng looked at her approvingly, nodded vigorously at her, and said with a smile: "Yes, that's fifteen kilograms!"
While saying these words, Han Cheng also gave Yuan a thumbs up.
Yuan, the priestess of the former semi-agricultural tribe, is indeed smarter than ordinary people. Mathematics has always been taught in the tribe. Most people in the tribe are good at addition and subtraction, but they are completely at a loss when it comes to multiplication and division.
Among the remaining people who can perform multiplication and division, a large portion of them can only calculate numbers on paper, but cannot apply them in daily life to solve practical problems.
But compared with most people in the tribe, Yuan, a female priestess of a former semi-agricultural tribe, has not been exposed to mathematics for as long as she should, only two months, and she has been 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 quite understand this, he still calculated the correct result independently.
Although I calculated it wrong the first time, it is already very rare.
After all, she had only been exposed to mathematics for a short time, and the practical applications were much more difficult than simply calculating numbers.
Sure enough, mathematics is a subject suitable for smart people, and talent is often very important.
When it comes to physical work, most people in the tribe are good at it and are not afraid of it at all, but once it comes to various academic matters, many people become weak in the arms and legs.
Chinese characters are relatively okay. After all, attracted by the popular works of the Qingque tribe such as "The Tadpole Looking for Its Mother" and "The Monkey Catches the Moon", people are still very interested in learning these.
But mathematics, which is more abstract and requires remembering many rules, is really a headache. Even Shi Tou, the best student in the tribe, scratches his head when it comes to mathematics. He can only do the simple four arithmetic operations so far, and he cannot understand or learn more advanced ones.
In the entire tribe, the level of stone is first-class.
Now that he has discovered Yuan, a good talent, Han Cheng naturally cannot let him go and needs to encourage him well.
This will help Yuan immerse himself better 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 knew the importance of mathematics. Especially after society developed to a certain level, Han Cheng understood even more clearly the role that higher-level mathematics could play in the development of society.
Advanced and complex mathematical knowledge is of course not useful when buying groceries, but there are many other things in this world besides buying groceries.
数学，当初学习的时候韩成确确实实被难为的要掉头发，而后来工作之后，用到的很少，但他却不会因此而否定学习数学的意义。
如今韩成来到了这个世界，自然不会将之遗弃。
被苹果砸到头的人，说站在巨人的肩膀子摘苹果比较容易。
相对于现在的部落而言，韩成无疑就是一个巨人，如果他能够将这些东西都给留下，那么今后的后代们，在他打下的这些基础上之上，也能够一出生就站在别人很可能终其一生都不可能达到的终点之上了。
以此为起点，总是能够走的更加远一些，能够将部落变得更加的好一些。
当然，这些都是许多年以后的事情了。
但是，抛去这些今后的事情，此时的青雀部落也一样需要数学知识。
比如对收获的粮食、换来的皮毛这些东西进行统计，。
按照人头来计算，青雀部落一年大约需要多少粮食才够吃？一条路，不一样数量的人去修建，分别需要多长时间才能收获完毕？
地里面的庄稼，众人一起动手的情况下大约多少天能够收割完毕……
这一系列的事情，都是需要依靠数学进行计算才能做到心中有数的。
误差虽然会有，但是却比估约莫准确的多。
其余不说，单单是这一次榨油如果不是韩成通过计算知道出油率相差太多，那油渣里面蕴含的油，可就要都浪费了。
听到圆说出十五斤，并且又得到了韩成的亲口确认之后，二师兄等人顿时就有些懵了。
十五斤虽然没有之前圆说的三十五斤多，但同样也不是一个小数目。
要知道，这一次总共也就是榨出来了三十五斤油而已，装了两罐子。
这十五斤的油基本上就能装一罐子了！
“神…神子，真的有这么多的油？”
二师兄有些结巴的看着韩成询问道。
韩成点点头，再一次的确认了这件事情。
见此，挠着头发的二师兄拎着青铜锤就要再去砸这些木桩，却被韩成给拦了下来。
经过这一番的考虑之后，韩成已经大致上想明白这次的出油率为什么和上次的相差那样大了。
这一次，放入的桐油果粉多，足足是上一次的十倍。
这样多的桐油果粉摞在一起，弹性会增加，不容易将之砸透。
用一句来概括就是贪多嚼不烂。
被韩成拦下的二师兄在那里挠头发，和他一起挠头发的还有巫以及刚刚计算出这里面还有十五斤油的圆，和其余更多的人。
二师兄的力气是部落所有人中最大的，这点是众人公认的，现在神子将二师兄拦下来，不让二师兄抡锤子，那剩下的油该怎么弄出来才好？
韩成拦二师兄当然是有原因的，二师兄的力量已经不能够将剩下的油给榨出来了，如果能够榨出来的话，之前就已经成功了。
这会就算是再次握着锤子一阵猛砸，也只是白费力气罢了。
“神子，那现在该怎么办？”
一众人看着韩成，眼中都是不解之色，连最有力气的二师兄都奈何不了这剩下的桐油，他们是真的没有办法好想了。
“我有办法，把它们给榨出来！”
人本身的能力是有限，游泳游不过鱼，奔跑赶上不马，更是不能如同鸟儿一样在空中飞翔。
但是，因为人有发达的脑子存在的缘故，能够制造出种种的工具，来解决面临的种种难题。
借助聪明才智，借助种种工具，能够能够上天入地，能够潜入深海……
当人体本身的力量达到上限之后，那么就需要借助工具了。
韩成这次制造工具很简单，就是一个撞锤，就跟寺院里面用来撞钟的差不多。
不过用作撞木的那一节木头，要比一般寺院的那种更大、更长、更重，冲击力相应的也就更大。
“咚！”
“咚！”
韩成用手拉着绑着撞锤上的绳子，将撞锤拉的往后方升起之后，就顺着撞锤往回反的力气，使劲的往回推。
蕴含着极大力量的撞锤，在韩成的控制之下，借着本身重量，以及在空中摆动的惯性，在加上韩成加诸在上面的力量，狠狠的一家伙撞在了木桩之上。
周围围拢了一圈看稀奇的人。
对于神子制造出来的这种工具，众人都选择相信，但是这种相信之中却又带着一些不太敢相信。
因为部落里力气最大的二师兄用青铜锤使劲的砸都砸不下去，现在并不以力气见长的神子，却说要凭借着这样的工具，把木桩撞下去，然后榨出油来。
纵然他们对神子都是感到由衷的信服，但是在这样的情况下，信服当中还是蕴含了一些不信出来。
然而，当粗木制成的撞锤在韩成的控制之下撞击在木桩上之后，在周围进行的围观的人，纷纷瞪大了眼睛，心里的那些不相信，在这一撞之下，全都化作了齑粉，转化为了吃惊与不可置信！
这一撞之下，部落里力气最大的二师兄用青铜锤都砸不下去的木桩，居然以肉眼可见的进度，被砸进去了一截。
“油！油！又出油了！”
在许多人都还在为这样的一幕而在吃惊之中没有回过来神的时候，有人指着简易榨油机的下方兴奋的喊叫了起来。
众人闻言纷纷去看，只见之前已经被认定没有什么油存在了的简易榨油机，在韩成拉着撞锤一下又一下的撞击之后，开始有油滴落，并且很快就从一滴滴变成了几条细线……
原来这里面真的还蕴含着这么多的油，原来把一截木头横着吊起来，真的有这样大的冲击力！
“来，跟我一起撞！”
韩成独自拉着撞锤撞了一阵儿之后，对站在一旁二师兄说道。
在韩成的示意下，二师兄站在撞锤的另外一边，然后和韩成一左一右的一起用力，把撞锤拉的往后扬起，再用力的往前推。
有了二师兄这个力量极大的人的加入，撞锤的优势被发挥的更加彻底了。
随着撞锤的一次次的撞击，木桩被一点点的砸入，越来越多的桐油被从里面挤压出来。
“神子，这个法子真好！”
看着那称重之后，足足达到了十七斤多的桐油，二师兄满是兴奋的说着。
使用这样的办法，不仅仅能够把桐油榨的干净，而且还非常的省力气。
纵然二师兄的力气大，但是在能省力气的时候，他也不想出力太大，把自己累得跟伸着舌头散热的福将一样……
因为榨油机的成功制造，并且韩成又弄出来了这样的一个省力而又高效的撞锤的缘故，青雀部落显得非常的欢喜。
那些活泼好动的未成年人们，没事了总喜欢往这里凑，抽着空子了总想过来推撞锤玩。
韩成也非常的欢喜，这一方面是因为他带着青雀部落的人，从无到有的将榨油机给弄出来了，部落里从今之后又多了一种机器，另一方面就是，圆真的跟他当初所设想的那样，在数学上表现的很有天分。
这就是聪明人的好处，在许多需要动脑子的事情上，进步总是很快。
这一次大规模的榨油成功之后，韩成没有让人再继续榨油，现在榨出来的这些油就已经够用了，剩下的桐油果可以等到冬天的时候在进行榨油，毕竟那个时候，部落里的人更闲。
这样的一番忙碌之后，秋意更剩，部落周边的草色变成了墨绿，早晨起来的时候，带着寒意的露水粘在草叶，看上去白茫茫的一片。
人从这里走过，草叶晃动之间露珠纷纷滚落，粘在脚面上，有些冻脚。
远处山林间，也变得色彩斑斓起来，虽未到万山红遍层林尽染的地步，不过也已经快了。
不住不觉间，青雀十年的深秋就已经到来。
院落之内，带着皮手套的韩成直接将一副藤甲浸在装有桐油的陶盆之内，来回翻转几下之后，整个藤甲之上就已经全都沾上了桐油。
用手拿着藤甲在陶盆上方等待了一阵儿，待到上面不再有油往下滴落，韩成就拿着这副藤甲挂在了不远处的一个架子上。
这个架子上已经挂上了十来副浸过桐油的藤甲，这会儿在深秋的阳光的照射之下，带着一些光亮，看起来很是好看。
“咚咚咚，咚咚咚……”
被熊猫团团驮着在部落里来回走的小豌豆手里拿着拨浪鼓，一边来回的摇着，一边咧嘴傻笑，开心的像个二傻子。
小豌豆手里的拨浪鼓看上去也有着一层的光亮，与之前的色彩暗淡的样子比起来，光鲜不少。
这同样也是度了几层桐油的缘故。
不过拨浪鼓没有丢进桐油盆子里泡，而是用白雪妹用蚕丝织出来的不成功的丝绸沾着桐油擦出来的，这样弄出来的上面不容易留下什么痕迹，看起来更加美观。
“笃笃笃……”
这是拐杖点在石板路上发出的声响。
随着这声响的由远而近，一手拿着拐杖，另外一手拿着一把野果的巫出现在视野里。
However, Wu's walking posture at this moment seemed very awkward. Every time he walked forward, his body would involuntarily lean towards the side where the crutch was, and the crutch was extended with a large amplitude and high frequency.
It doesn't look like he is walking, but rather like he is showing off his crutches.
In fact, Han Cheng had asked Bo and Wu to make this crutch a long time ago, but Wu felt that using a crutch would make him look old and would not highlight the strength of his body, so he just left it there and never used it.
However, ever since Han Cheng soaked the cane in mint juice for a few days, dried it, and then wiped it several times with a silk cloth dipped in tung oil, Wu couldn't walk without the cane, and carried it with him wherever he went...
