primitive survival evolution

Chapter 85 Oil Pressing
Everyone surrounded the crooked neck tree and observed for a long time, but they couldn't find the reason.

I went around the mountain and found nothing suspicious.

On the contrary, there are a lot of olive trees here, and a lot of olives have accumulated on the ground, some of which are rotten.

At the same time, there are many dodos here. The meat of the dodos is very bad, and people are not interested in them, so they are not afraid of people.

There are also many dodos and olive trees on the next few hills.

There are also many wild deer, mice, and wild cats who come here to eat the fruit. The dodo has no natural enemies in this valley.

There are many dodo nests here, Li Yan and the others walked around a few times and picked up ten dodo eggs.

Dodo eggs are only the size of a fist, with some purple spots on the surface, and can be used to make animal feed.

They also picked up about ten catties of olives.

The settlements on the tribal mountains have also started to be built. There is food in winter, and the tribal people seldom go out to hunt.

Therefore, they rushed to build houses, expanded the stone tool shed, rebuilt the house for storing tools, and expanded the place for storing herbs. In addition, they also built a large granary here.

People work together and work together.

A few days ago, two old people died of illness, but seven children were born, and now the population of the tribe has exceeded 80.

After handing over the dodo eggs to Wen Shi in the feed room, Li Yan called Jiang Tu and a few women together, and he planned to squeeze olive oil.

Oil pressing, as the name suggests, is pressing, and the olive fruit is directly pressed out of the oil inside, which is cold pressing.

Cold pressing can preserve the nutrients of the fruit to the maximum extent, but the oil yield is twice as low as steaming and pressing.

Li Yan needs a lot of oil, and he wants to use the olive trees in the mountains behind the tribe, so he chooses to steam and press.

So he found a primitive pottery—甑【zèng】.

This is a kind of earthenware for steaming and cooking food.

A 鬲 [lì] for cooking porridge and a pot with many small holes in the bottom, these two pieces of pottery are combined into this steaming cooker, which can steam any grain and meat.

Li Yan used this steamer to steam the olives and put them in a basket.

Next, he went to the tool room and found a chainsaw.

This is the only saw in the tribe. It is more than one meter long. It was made a long time ago, but the tribesmen thought it was not as useful as an axe, so it was hidden in the snow after a few times of use.

Holding a saw, a few chisels, and a hammer, Li Yan led a few women down the mountain.

Came to a forest at the bottom of the mountain.

Many trees here have been cut down by people, and now they are all dry logs, and the tribesmen come to collect firewood every once in a while.

Li Yan and the others found a tree stump in the woods. The diameter of this tree stump was one meter.

It's a great platform.

He and the women used iron tools to process the tree stump into a dented platform, and then he sawed a wooden stake. The length of the wooden stake was more than half a meter. The density of this kind of wood was relatively high, and both ends were sawed flat , a very strong cylindrical wood pile.

Once processed, he starts pressing.

Put the cooked fruit in the middle of the stump, and then press it with a cylindrical wooden stake, and press it hard.

The fruit was broken and some oil splashed out.

However, the squeezing force this time was too small, and with the weight of two people, the fruit could not be completely crushed into slag, which was obviously not possible.

what else can we do?

Li Yan sat on the ground and thought of a solution.

In less than half an hour, he thought of a solution again.

He ordered a mammoth to be brought in.

He remembered that when he was watching TV in his previous life, he had seen some mahouts who would use elephants to open walnuts.

The mammoth brought here was called Xiaohui, and Li Yan taught it to step on the wooden stakes. After teaching it for half a day, it finally achieved something.

On the second day, Li Yan tried to make it step on a stake to extract oil.

Xiao Hui is [-] meters tall and weighs nearly ten tons. It was seen stepping on a cylindrical wooden pile with one leg. Under the command of the people, it stepped on it hard, and with a "poof", all the fruits under the wooden pile were crushed. Slag.

The green oil slowly overflowed from the bottom of the cylindrical stake, flowed into the grooves of the stump, flowed out through an opening, and then fell into a clay pot along a branch.

I squeezed ten catties of olives and collected four catties of oil. The oil yield is not bad, and it can be improved in the future.

However, the olive oil in the clay pot has a lot of impurities, and after a taste, there is a strong astringent taste and a lot of slag.

"This oil is not filtered." Li Yan frowned.

Jiang Tu also took a sip, and said with a look of disgust: "Patriarch, this kind of oil is so unpalatable, what's the use?"

"It's useful, it's definitely useful. We can eat it ourselves, and we can sell it to other tribes." Li Yan said, "There are so many olive trees here. If they can be used, the tribe will have a stable output of resources in the future."

Li Yan took the can of oil back to the cave on the mountain.

He came to Sakura's stone bed, and she went down the mountain to burn pottery, but she wasn't here.

On this messy stone bed, there are a lot of animal skins and hay rolled up, almost like a doghouse.

"I remember buying a linen dress for her during the autumn meeting."

"Where do you put it?"

Li Yan rummaged through her bed, searched for a long time, and finally found the linen dress in the crevice of the stone.

This is a linen garment produced by the Ziyi tribe, with wool sandwiched in the middle of this garment, the workmanship is fine, and it is worth [-] Bei coins, which is relatively expensive.

"It seems that I haven't seen her wear it a few times. I guess she doesn't like it."

Li Yan shook his head, then took out the obsidian blade, cut off a piece of sackcloth, stuffed the clothes back, and restored the animal skins on the bed to the way they were just now.

"That way she doesn't know that someone has turned over her bed."

He took the sackcloth, returned to the hole, and squatted on the ground.

Wrap the oil filling mouth with sackcloth and put it upside down in another clay pot.

I saw the yellow-green clear oil flowing down little by little, and the oil was shining, which was really beautiful.

A lot of slag was filtered, but the oil obtained was clear with very few impurities in the oil.

Li Yan quickly took a sip and said happily: "The filtered oil is really good, but there is nothing amazing about it. We have to find a way to make it easier for other tribes to accept it."

Putting the jar of oil back beside his bed, he wondered what vegetables or meats could highlight the benefits of the oil.

As soon as he came to the field at the foot of the mountain, he saw a large group of people approaching Taniguchi.

There are mammoths, giant oxen and giraffes.
He stopped and looked at it, and after a moment the group approached.

It turned out to be the Niu Tribe, the Kui Kui Tribe, and the Lianshan Tribe.

Li Yan realized that they were here to retrieve the goods and make a deal.

The Kuikui tribe came to sell long-necked camels, the Lianshan tribe came to get ten medium-sized pottery jars, and the Niu tribe came to send potatoes and carrots.

During the visit of the Niu tribe, in addition to delivering vegetables, their patriarch Niu Jiao also came in person, and several of their cows also carried several baskets of red fruits.

Niujiao smiled and said: "Patriarch Yan, our Niu tribe has a new fruit, you will definitely like it"

　Thanks for the reward of the four spirits
