I am a primitive

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 35 catties is not as much as the [-] catties that Yuan said before, it is also not a small amount.

You know, this time, a total of 35 catties of oil was 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 slammed it 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.
