I am a primitive

Han Cheng howled excitedly, and the people around him also shouted excitedly: "The oil is squeezed! The oil is squeezed!"

Then there was a jubilant and busy scene. Everyone was frying tung oil fruits, peeling, smashing and mashing them with great interest.

And here, after no oil dripped from it, Han Cheng began to put the tung oil collected in the clay basin into the jar.

Then use a scale to weigh, and after the weight of the jar itself is removed, the oil obtained this time is a little more than five catties.

The tung oil fruit powder put into it this time is about 35 catties, that is to say, the oil yield is about one-seventh of the tung oil squeezed by this method.

This kind of oil yield rate is not high. There must be a lot of unsqueezed oil in the oil residue of the two dumplings, but it doesn't matter to Han Cheng now.

As long as most of the oil in it can be squeezed out, there is no problem. As for the rest, just waste a little bit, who made the oil press machine so rough, and the tung oil fruit resources there are like this Is it sufficient? !

At this moment, looking at the tung oil in the jar in his hand, Han Dashenzi looked extraordinarily proud, and four words appeared on his face, that is, rich and self-willed.

After everyone's busy work, more tung oil fruits were processed, and this time they put a lot in it, a full 350 catties!

In order to put more tung oil powder inside, these tung oil packages were not packed loosely like before, but were trampled firmly with their feet, making them into pancake shape.

Only in this way, new problems appeared.

The problem is that the pancakes trampled on by people are of different sizes. After one is placed next to the other, the big ones are big and the small ones are small, leaving a lot of gaps in the middle. The place will not be squeezed in the next oil extraction, which will greatly affect the oil yield.

After standing here and scratching his scalp for a while, Han Cheng came up with a solution.

He called Liao over, and asked Liao to weave circles of the same size with bamboo strips.

The halos woven from bamboo strips are 45 centimeters in diameter and four centimeters thick.

With these circles of the same specification, the situation of pancakes of different sizes and thicknesses is solved at once.

When making oil cakes, you only need to spread the linen cloth on the ground first, then put the circle on the linen cloth, and then continuously fill it with tung oil fruit powder. Tie the corners of the linen to each other.

And because there is a relatively hard bamboo ring on the outside, after standing up the pancakes, these pancakes will not deform as easily as before.

With the experience of last time, this time when putting the pancakes inside, instead of closing the 'lid' as before, and then putting them inside after binding them dead, first put the pancakes one by one on top of each other. The lower side is lined up neatly, and the circular plank is leaned against the end. After everything is done, the upper half of the tree trunk is covered and tightly tied with tough vines.

"Start squeezing the oil!"

Han Cheng yelled, and several people began to fill it with wooden stakes one by one.

Because there is a lot more tung oil fruit powder in it than before, so this time these wooden stakes are left outside for a long time.

"Bang! Bang!..."

After filling it tightly, the second senior brother cheered up and started smashing the wooden pile with a bronze hammer in his hand.

At the very beginning, the stakes went in very quickly, but as the number of smashes increased, the speed began to slow down, but in contrast, there was tung oil dripping from the bottom of the oil press.

This time, the tung oil fruit powder was put in enough, ten times more than the first time, so after the second senior brother continued to swing the hammer for a while, the tung oil that was originally dripping down directly turned into a trickle and flowed down. The earthen basin below was dripping.

Such a scene made Han Cheng and the others smile happily.

The second senior brother also cheered up, and smashed down with one hammer after another, constantly squeezing the tung oil powder.

After all, human strength is limited. After the second senior brother smashed it for a while, he was tired and out of breath, and the strength of the hammer he swung was not as strong as before, so the senior senior brother stepped forward to take over...

Looking at the pot full of tung oil, Han Cheng and the others were extremely happy.

With these tung oils, Shenzi can finally start brushing rattan armor, and the quality of his tribe's rattan armor can finally go a step further!

The joy in Han Cheng's heart was weighing the tung oil squeezed out in batches, and it became lighter after adding up.

The tung oil looked quite a lot in the basin, but after weighing it was only 35 catties.

Calculated according to the oil yield rate recorded during the last experiment, this time you should get [-] catties of oil.

Even if this batch of fruit is not as plump as the previous batch used for the experiment, it is impossible for the difference to be so large, it is just fifteen catties less!

Where did the fifteen catties of oil go?

"Smash it again."

After Han Cheng thought for a while, he said to the second senior brother who had recovered a lot. The second senior brother picked up the hammer and continued to smash the wooden pile.

It's just that under his continuous pounding, the wooden stake basically stopped entering, and only a few sporadic drops of oil dripped from it.

"Son of God, there is no more oil in it."

Wu was talking at the side, but Yuan didn't follow up, but showed a thoughtful look on his face.

Today's circle has been initially introduced into the world of mathematics by Han Cheng after nearly a year of shocking influence from the Qingque tribe.

From Han Cheng's weighing just now, she also saw some tricks.

-------------Chapter Dividing Line---------------

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?
