Chapter 807 The Son of God, there is no more oil (three in one)
(The previous chapter may have involved some sensitive words and was blocked. It may take two days to be released...)
Now there are generally two key issues that need to be resolved.
One is how to make a larger wooden pit on the wood that can accommodate more things, and the other is to solve the problem that the wooden wedge is nailed into the wooden pit and there is no way to pull it out.
Especially the later question about wooden wedges.
If this problem is not solved, the oil extraction business will not be carried out.
Even though time and effort were worthless in the primitive era, after working on it for so long and laboriously, only a disposable product was produced, and this disposable product could only squeeze out about ten kilograms of oil.
Even if Han Cheng is used to a slow-paced, low-efficiency life, he still can't accept it when faced with things like effort and labor that are not proportional.
"Son of God, can you dig a hole along the trunk of the tree?"
After hearing the news that Han Cheng said that in order to create a pit that could hold more tung oil fruits, it might be necessary to cut down thicker trees, Mao Er's childish face twitched a little.
Because it is already a lot of trouble to bring down the current tree completely. If we put down another tree that is thicker than this tree, it will be even more troublesome. Not to mention the rest, the tribal people
The big bronze saw is no longer long enough and needs to be rebuilt to be longer.
Because he didn't want to cut down a bigger tree, Mao Er stared at the thick tree trunk lying flat on the ground and began to think about how to make a bigger tree hole without cutting down bigger trees.
After thinking about it for a while, he actually asked him to come up with a solution.
After hearing Mao Er's words and looking at the thick tree trunk lying flat on the ground, Han Cheng was suddenly awakened.
How could I have forgotten this method!
Digging a wooden pit perpendicular to the tree trunk will be greatly limited by the thickness of the trunk itself. However, as long as you dig the wooden pit from one end to the other along the direction of the trunk, as the length increases,
The wooden pit can be made much deeper, and the capacity will naturally increase.
"Okay! Okay! Mao Er, your idea is really great!"
Han Cheng, who was smiling all over his face, patted Mao Er's shoulder vigorously and did not hesitate to praise him at all.
Mao Er, who was still a little worried at first, now saw that the Son of God was not only not angry, but also praised him so much. The little bit of worry in his heart had long since disappeared, leaving only deep joy and fullness.
of excitement.
I also solved a problem myself!
"After it was erected, it was too high. I had to stand on the wall and smash wooden wedges into it."
After Wu stood aside and figured out what to do, he scratched his head and said loudly.
"It doesn't matter if you don't stand on the wall. You can build a shelf and stand on the shelf to smash it, just like when we unwrap wooden boards."
After receiving the praise, Mao Er's thinking was very active and he was quite excited. He immediately came up with another solution.
When the tribe is sawing tree trunks into wooden boards with a big saw, if they encounter those trunks that are too high, they need to set up a frame on both sides of the trunk, and two people stand on the frame and pull the saw hard.
So it’s not surprising that Mao Er came up with such a solution now.
Han Cheng smiled and waved his hand. There was no need to stand the tree trunk up when he smashed the wooden wedges inside. You could just keep the tree trunk lying flat and smash it in.
After all, this is something that can be done by one person, unlike a saw pulled by two people.
After Han Cheng said such a method, the eyes of Wu, Lai, Maoer and other people who were not far away from Han Chengcheng suddenly lit up. This was indeed a good method.
So Han Chenggong began to arrange for people to dig out the wooden pit along the intact end of the thick oak wood, and at the same time, he also had people saw off the other end, which was destroyed after the wooden pit was dug out.
When I first chose this tree, in addition to the appropriate thickness, another reason was that the tree was handsome, tall and tall.
Now even if another section is cut off, the remaining part is still nearly six meters long, which is enough for use.
At this time, Bigfoot's body was no longer in trouble. He was directly released from his slave status by Han Da Shenzi because of the discovery of tung oil fruit and became a second-level citizen of the tribe. Now he is very motivated and can't wait to dedicate his whole body to the Qingque Tribe.
Under great construction.
So he felt fine just now and came to see Han Cheng, saying that he wanted to go back outside to build roads.
Seeing that he was healthy and still so positive, Han Cheng agreed after asking him to pay more attention to rest.
After seeing that Bigfoot's life was not in danger, the few people who sent Bigfoot back left the tribe the next day and went back to build roads again.
Even so, Bigfoot will not be lonely on this trip, because in addition to some members of the trade team, there are also some women and minors from the tribe who are going with him.
They went there to pick up some tung oil fruits and then brought them back.
A group of more than 20 people headed west along the newly built road.
There were four donkey carts traveling with him.
The minors were sitting on the donkey cart, full of novelty and joy. Some people were lying on the donkey cart, looking through the gap in the cart board to see the retreating ground. (No nonsense, just looking through a small gap,
The things on the ground retreated really fast, and the ones we rode back then were still slow ox carts)
Some people were lying on the donkey cart and looking at the clouds that they couldn't get rid of and moving with them. Some minors were pointing at the unseen scenery on both sides of the road and were very excited.
The donkey cart moved forward, leaving behind laughter along the way...
Within the tribe, the work of digging holes has stopped again, and problems have once again been encountered at work.
The problem this time is still more difficult.
Drilling holes in the tree trunks went smoothly at the beginning. After all, Lame and the others have become old carpenters. It is not a problem to dig such holes. However, as the holes continue to deepen, the problem becomes bigger.
It slowly appeared.
As the cave deepens, it becomes more difficult to dig. When Lame and the others managed to make the pit nearly two meters deep, they could no longer dig deeper.
At this time, there were still nearly four meters behind the thick tree trunk that had not been dug.
Even if a section of the end needs to be left uncut, there are still three meters that have not been cut.
"Son of God, forge longer tools..."
Lame, who was inspiring to become like Lu Ban, was worried this time and made up his mind to dig the hole in the tree trunk.
After thinking for a while, Han Cheng shook his head. This was too much trouble.
And even if you can make a five-meter-long chisel, it is very difficult to use this five-meter-long chisel to dig a regular hole. This requires too much skill and physical strength of the carpenter.
"Let's saw this tree trunk open, from beginning to end, and cut it in half from the middle."
Han Cheng looked at Lai and said.
"this……"
Lame seemed hesitant. He was worried that after sawing the tree trunk from the middle with a saw, there would be no way to extract oil. After all, when he dug the wooden pit for oil extraction, Shenzi specifically told him not to break it.
And they themselves felt that if they got this thing open, they might not be able to use it to squeeze oil again, because when they nailed the wooden wedges inside, it would be very strong.
"It's okay, let's try sawing it open."
After understanding Lame's worries, Han Cheng smiled and waved his hands.
Han Cheng had never come into contact with this kind of artificial oil press before, but now he could try it out and learn while fighting.
We were encountering difficulties in digging the tree pit, and it reached the point where we could no longer dig deeper without breaking it open.
At this time, there is no other way to think of it but to get it open.
As for how to put the two pieces of wood back together after breaking them apart, that is what needs to be solved after breaking them apart.
Follow orders lamely.
So, it didn't take long for the battered tree trunk to 'stand' up again with the joint efforts of everyone. Then two people who often pulled big saws began to stand on the erected frame, pushing and pushing.
He started sawing from top to bottom...
After the tree trunk was broken in half, it became easier to start cutting again. Several carpenters started cutting there in batches according to the lines drawn by Lame. Compared with before, the progress was improved by four or five times.
However, although the progress has been improved so much, the people who are working at Lame do not feel much excitement, because they are all feeling vaguely worried about what will happen next. I am afraid that the tree trunk that has been sawed from the middle will not be ready for the next time.
After closing it again, it doesn't work.
After more than two days of polishing, the two halves of the trunk were completely dug out, with a semicircle on each. When put together, they turned into a hollow cylinder.
"How about trying some tung oil fruits."
Lame wanted to find a way to glue them together as much as possible, but Han Cheng thought for a while and did not give in. Instead, he asked people to directly put tung oil fruits inside to conduct experiments.
Because the tree is thick enough, even if part of it is removed, the rest is still very heavy.
Now one is pressed on top of the other, which is much heavier than the legendary coffin lid.
Han Cheng wanted to try to see if he could withstand this support with just his own weight. If he could, it would be great and save a lot of trouble.
The people who went to the road construction area to collect tung oil fruits have returned, pulling four donkey carts. The people who followed did not come back empty-handed, and they had more or less something with them.
If the 'oil press' can be set up properly, the oil extracted from the tung oil fruits brought back from the tribe can basically be used to brush the vine armor.
Under Han Cheng's instructions, after going through the procedures of stir-frying, shelling, pounding, and wrapping, a package filled with fried tung oil powder was filled and placed sideways. I don't know if it can be used.
Inside the oil press.
This time, two packages of tung oil powder were filled inside, weighing almost thirty kilograms.
After pushing them to the bottom with a stick, just like the unsuccessful experiment last time, a round wooden board with a thickness similar to the inside was filled inside.
After doing this, I started to put wooden sticks inside one by one. When a certain number of wooden sticks were stuffed and it was difficult to stuff them with my hands, I started to add the bronze hammer.
"Dong dong dong..."
The sound of hammers hitting wooden sticks and nailing nails continued. The surrounding area was quiet. Everyone was looking at the modified oil press, waiting for a miracle to happen.
Lame, people like Maoer who were involved in the entire production process didn't even dare to express their anger. They stared at it without blinking, and their hearts were on tenterhooks, for fear that something would go wrong.
However, errors still occurred.
Facts have proved that it is impossible to seal the coffin lid tightly without nails.
At the beginning, the support force was not very strong. Relying on its own heavy weight, the half of the tree trunk pressing on it could not move at all. However, as these tree sticks were continuously nailed into the inside, the support force inside became stronger.
It grew bigger and bigger, and finally the upper half of the trunk was stretched out and there was a gap.
"Alas~"
Lai and the others sighed together, feeling very disappointed with this result.
Although Han Cheng was a little disappointed, it was not serious. After all, this thing was made from scratch, and any kind of mistakes could occur in the process.
Immediately, someone lifted up the upper board, removed the stick, and reloaded it.
This method of sawing the tree trunk in half was originally thought up to solve the problem of digging a hole. Now, by accident, the problem of being unable to take out the wooden stakes that were driven in was also solved.
.
No matter how firmly these wooden sticks are held inside, as long as the upper half of the trunk is opened, the strength will disappear immediately, and the firmly held trunk will become loose.
After loading these things again, Han Cheng asked someone to find some tough vines and tie them up tightly, binding up to a dozen of them.
After finishing these, continue to fill in the wood piles. After filling them tightly, use a bronze hammer to continuously drive in.
"Oil! Oil! There is oil!"
This time, with these vines for restraint, as the stumps were continuously driven in, the upper half of the trunk was not stretched open.
After smashing it for a while, a sharp-eyed person pointed at the bottom of the simple oil press and shouted in surprise.
When Han Cheng and others around him saw this, they all looked there.
Han Cheng was immediately overjoyed when he saw this. He saw drops of yellowish oil flowing out from the holes drilled in the bottom of the simple oil press, and then dripping into the pottery basin below.
This scene is not very beautiful, but Han Cheng is looking at it with a smile on his face, and Lame and Mao Er, who have participated in the whole process of making this simple or crude oil press, are even jumping up and down.
Cheered loudly.
The second senior brother, who was holding the bronze hammer and hammering the tree stump, lowered his head to look at the drops of oil dripping down. After grinning, he held the bronze hammer with both hands and increased the strength, one after another.
Knock it on.
As the squeezing force increases, more grease comes out, from a droplet dripping down at the beginning, and turns into a thin line, continuously dripping into the pottery basin below, from less to more.
There were cheers all around, and everyone had happy and exciting smiles on their faces.
This is what success tastes like!
Before success, it often takes a lot of hard work, a lot of pain, and endurance, but when all of this passes and success really comes, all the hard work has turned into heartfelt joy.
And the more people give and the more suffering they experience, the more intense the joy they will get at this time.
You can understand this clearly just by looking at a happy lame who jumps higher than a person with nimble legs and feet.
Because of the appearance of this oil, the entire tribe suddenly became a sea of joy.
Under the hammer blows of the second senior brother, these tung oil fruit powders were squeezed into a more porcelain solid state, and the oil contained in them continued to flow out, gathering a piece of amber color in the pottery basin.
"Fried the tung oil fruit, peeled the tung oil fruit, crushed it and squeezed out the oil!"
Han Cheng howled excitedly, and the people around him also shouted excitedly: "Extract oil! Extract oil!"
Then there was a joyful and busy scene. Everyone was frying tung oil fruits, peeling them, and pounding them with great interest.
And here, after no oil dripped from it, Han Cheng began to put the tung oil collected in the pottery pot into the jar.
Then use a scale to weigh it. After subtracting the weight of the jar itself, the oil obtained this time is a little more than five kilograms.
The amount of tung oil fruit powder put into it this time is about thirty-five kilograms. In other words, if the tung oil is squeezed in this way, the oil yield rate is about one-seventh.
This oil yield rate is not high. There must be a lot of oil that has not been squeezed out in the oil residue that the two dumplings were poured aside, but this does not matter to Han Cheng now.
As long as most of the oil inside can be squeezed out, there will be no problem. As for the rest, just waste a little. Who would let the oil press you made be so rough, and the tung oil fruit resources there are like this
Is it enough?
At this moment, looking at the tung oil in the jar in his hand, Han Dashenzi looked particularly proud, and four words appeared on his face, that is, he is rich and willful.
After everyone's busy work, more tung oil fruits were processed. This time, more tung oil fruits were put in, a full three hundred and fifty kilograms!
In order to put more tung oil powder inside, these tung oil packages were no longer packed loosely as before. Instead, they were stepped on firmly with their feet and became like pancakes.
But as a result, new problems arise.
The problem is that these pancakes that have been stepped on by people's feet are of different sizes. After they are placed next to each other, the big ones will be bigger and the smaller ones will be smaller. There will be a lot of gaps in the middle. In this case, there will be a lot of gaps.
The area cannot be squeezed during the subsequent oil extraction, which will greatly affect the oil yield.
After Han Cheng stood here and scratched his scalp for a while, he came up with a solution.
He called Lai over and asked him to weave circles of the same size out of bamboo strips.
The haloes woven with bamboo strips are 45 centimeters in diameter and 4 centimeters thick.
With these circles of the same size, the problem of different sizes and thicknesses of pancakes is solved at once.
When making oil cakes, you only need to spread the linen cloth on the ground first, then place the circle on the linen cloth, and then continue to fill it with tung oil fruit powder. After it is almost done, fold the excess linen cloth in half, stamp it firmly with your feet, and put it in place.
Just tie the edges of the fine linen to each other.
And because there is a relatively hard bamboo ring on the outside, after the pancakes are erected, they will not deform as easily as before.
Based on the experience from the last time, this time when filling the pancakes inside, I did not close the 'lid' first and tie it tightly before loading it inside as before. Instead, I first put the pancakes one by one one by one.
The lower side was arranged neatly, and the round wooden board was placed at the end. After everything was done, the upper half of the trunk was covered and tied tightly with tough vines.
"Start pressing the oil!"
Han Cheng shouted, and several people began to fill the wooden piles inside one by one.
Because a lot more tung oil fruit powder was put inside this time than before, the wooden piles remained outside for a long time this time.
"Bang! Bang!..."
After filling it tightly, the second brother roused himself and started pounding the wooden piles with a bronze hammer in his hand.
At the beginning, the wooden stakes went in very quickly, but as the number of hits increased, the speed began to slow down, but in contrast, tung oil dripped from the bottom of the oil press.
This time, the amount of tung oil fruit powder was very sufficient, ten times that of 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 turned into a trickle, flowing towards
The pottery basin below was dripping with water.
Such a scene made Han Cheng and others smile with joy.
The second senior brother also cheered up and hammered down one after another, constantly squeezing the tung oil powder.
After all, human strength is limited. After hammering for a while, the second senior brother was exhausted and out of breath. 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 pottery pot full of tung oil, Han Cheng and others were extremely happy.
With these tung oils, Shenzi can finally start painting the vine armor, and the quality of his tribe's vine armor can finally be improved!
The joy in Han Cheng's heart became lighter after weighing the tung oil extracted this time in batches and adding them up.
The tung oil looked a lot when placed in the basin, but after weighing it, it was only thirty-five pounds.
Calculating based on the oil production rate recorded during the last experiment, we should get fifty kilograms of oil this time.
Even if all the fruits in this batch are not as plump as the last batch used for experiments, there is no way the difference is so big, it is just fifteen kilograms less!
Where did these fifteen pounds of oil go?
"Smash it again and see."
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 piles.
But under his constant pounding, the wooden stakes basically stopped going in, and only a few drops of oil dripped from the inside.
"Son of God, there is no oil in it."
Wu was talking to the side, but Yuan did not follow, but looked thoughtful.
Now, after being shocked and influenced by the Qingque tribe for nearly a year, Yuan Yuan has been initially introduced to the world of mathematics by Han Cheng.
From Han Cheng's weighing just now, she also saw some clues.
