The copper-smelting clay blast furnace renovated by the kiln has been burning for five days.
What started as billowing black smoke slowly turned into light yellow smoke.
The whole kiln factory was filled with a choking smell.
Fortunately, the terrain at the foot of the mountain is open, and there were two heavy rains along the way, so the smell was quickly blown away and had little impact on people.
Every morning and evening, Xu Chen Lei Dingfeng would come to visit a few times to watch the changes in the kiln fire and feel the temperature of the blast furnace.
Fortunately, after more than half a year of training, the four kiln workers can be regarded as experienced kiln workers. They are already experienced in raising and maintaining the temperature of the kiln fire, and they do not need any guidance or reminders from Xu Chen.
In fact, Xu Chen can't give guidance now. He has never fired a kiln before. He is just a simple theorist, commonly known as a talkative expert.
According to Xu Chen's estimate, it would take at least ten days to smelt copper.
Therefore, apart from inspections in the morning and evening, he could only wait.
There are more than 300 kilograms of copper ore in total. The composition is relatively mixed. The most is chalcocite, then bornite, and there is also some chalcopyrite, and there are even a few high-purity natural copper nuggets and malachite.
.
Natural copper nuggets, like gold nuggets, are rare in nature and are very valuable minerals.
Malachite is a companion product produced by copper mines under high temperature and pressure during the ancient formation period. It has high ornamental value and is very similar to turquoise, but there are still differences between the two.
Malachite is mainly green, while turquoise is mainly blue.
Both are copper-containing minerals, but their chemical composition and structure are very different, and their hardness and density are different.
Copper nuggets, turquoise and malachite were collected as gemstones by several tribes and used as decorations, while the ores were mainly used as pigments.
Based on the analysis of the copper-containing ores from here to here, Xu Chen concluded that there must be a large-scale copper mine within a radius of a hundred miles.
Maybe it's in the valley where the Wu people live.
And near the farthest Cang tribe’s habitat, there should be a gold mine of considerable size.
There is copper and gold. If the tribe can really develop, this will be a geomantic treasure land for the founding of the country.
However, the first priority right now is to successfully smelt copper, and then find lead and tin to produce bronze.
Only with a large number of sharp metal tools can human beings truly have the ability to fight against heaven and earth.
The purity of the copper ore in front of him is very good. According to his judgment and analysis, if all of it is smelted, he can get more than thirty kilograms of copper. However, this is only a theoretical value. There is still a lot of slag that cannot be cleaned.
If you can gain twenty pounds, it is considered a huge success.
What can you do with twenty pounds? Make a copper hot pot?
The sword is definitely useless, why not just make a hammer?
Xu Chen was a little confused.
While observing and waiting, I took the time to slowly make several clay models with clay for later use.
In any case, being able to smelt copper is the most meaningful thing he has done since traveling through time.
The realization of this skill will be of epoch-making significance for himself and for the development of human civilization.
…
In the passage leading to the courtyard, there is an extra rattan lounge chair.
This is a reward Xu Chen gave himself after being inspired to make the cradle and crib.
In the southwestern region, it is almost traditional to use bamboo to make deck chairs, which can be found in every rural household.
In many places in Guizhou, even houses and furniture are all made of bamboo.
He hasn't found bamboo yet, but there are many green vines on the mountain. This kind of green vine is flexible and slender and is very suitable for weaving things.
It’s the same principle as making the rattan sedan that carried the witch last time.
The frame of the lounge chair is made of wooden sticks of different lengths tied together, and then the back of the chair is woven with ivy.
Although this is my first time making a recliner, I still have a rattan sedan, a cradle, and a crib to practice with. Therefore, except for the slightly unsatisfactory proportions of the rattan recliner, the details have been handled very well.
Because of the complex structure of the recliner, it took him three days to complete it.
The tribesmen didn't know what he was making at first, they just thought it was a cradle or crib, or a rattan sedan.
When the reclining chair was completed and Xu Chen lay down on it contentedly, all the tribesmen couldn't help but exclaimed, once again completely impressed by his brain-burning magical creativity.
It's the hottest summer right now. It's uncomfortable to sleep day and night. The room is small, airtight and stuffy. Even if there is only a straw mat on the bed, it's still difficult to fall asleep. But this kind of recliner is transparent from top to bottom. As long as there is a trace of
There is a slight cool breeze, and the whole person can feel extremely cool.
Therefore, after this wicker chair was completed, it instantly became the favorite of the entire tribe.
Men, women, old and young are vying to lie on it and feel the comfort and coolness brought by this magical lounge chair.
Xu Chen slept directly on the recliner during the past two nights. The monkey on the left and the wolf on the right were guarded by two groups of mythical beasts. They lit two bunches of dried mugwort and Polygonum in front of the feet and behind the head, bathing in the passage.
The light cool breeze finally gave me a nice and cool sleep for two nights.
But as long as Xu Chen is not on the recliner, there will always be someone lying on it.
Everyone liked it, and Xu Chen was too embarrassed to occupy it alone. The child was fine, so he could just drive it away, but sometimes it was a mother, several older women, or even a pregnant woman lying on it to rest, and he could only endure the pain.
Just pinch your nose and find another place to rest.
In order not to cause family conflicts due to competition for deck chairs, he simply took two tool men to build a row of rattan beds against the walls on both sides of the entrance passage.
The structure of the summer bed is more simple and rough. It is to build a row of wooden frames with wood as thick as an arm, with thinner wooden sticks densely tied half a foot apart, and then weaved together with tree vines. Finally, there is a row of long wicker beds.
It is about 1.5 meters wide and can sleep horizontally or vertically.
So since the summer bed was built, the entrance passage has become the favorite place of all the tribesmen. A large group of women, children, old and weak people who keep the house sit on the summer bed all day long, weave, chat and take care of the children. After the adult men and women who work outside come back,
It is also the first time I sit on it and rest.
It's only when you go to bed at night that the place becomes really lively.
As long as it doesn't rain, no one is willing to go back to their room to sleep. A large group of people, old and young, huddle on the sunbed, light bunches of incense bundled with mugwort and Polygonum, and chat, sing, and blow the willow flute and leaves in the night.
, a few monkeys and two little wolves were crawling around under the cooling bed, and a group of children were playing hide and seek, making it extremely lively.
At this time, Xu Chen always lay on his recliner with a contented mind, listening to the sounds of the tribesmen chatting and playing with a contented face, looking at the river beach and the towering mountains in the distance, as well as the stars and moon in the sky or
Under the dark night sky, in this primitive and barbaric era, you can enjoy rare leisure and comfort.
It has been almost a year since time travel to now in the blink of an eye.
It is already mid-May, but last year it would have been mid-June.
This year, the Ba clan has undergone tremendous changes, but for him, the gains have not been great and he is still in a single-player state.
The Ba ethnic group is too small, and the nearby tribes are too far away. Due to the weak need for communication, communication is almost semi-isolated.
Therefore, until now, apart from clarifying the general situation near the tribe through two short exchanges in the Spring and Autumn Period, Xu Chen still had almost zero knowledge of further places.
Judging from the current situation, his task of upgrading tribal civilization will continue to be a stand-alone state for a long time.
If you want to connect to the Internet, you must first solve the problem of food, clothing, transportation.
In addition, you need to work hard to send out troops and equipment, and don't hang up just after connecting to the Internet.
As a Taoist who is not used to living by looking at other people's faces, you are really strong only when you are strong. You must ensure your own safety and life, and then consider the overall development of the tribe and the entire human civilization.
Everyone of the Ba tribe is very satisfied with their current living conditions, and they respect him enough. He cannot use these tribesmen, who are so simple and have no distracting thoughts, to shed their blood for his so-called kingship of unifying the nine states.
Stability is the most important thing, not to mention that the powerful Wu tribe is still watching closely.
The so-called stand-alone computer is not safe either. Before the time travel, the Time and Space Administration had already set up a living environment for him in advance. The Uzbek tribe was the first computer task he had to face before going online.
Once the Uzbek people are dealt with, the game really begins.
But he knew nothing about the current situation of the Uzbek people.
Since the great witch came back in mid-March, there has been no news for two months.
In addition, the river swelled and flooded the beaches on both sides, and the roads were completely cut off.
In this state of ignorance and helplessness, he had no other choice but to watch the Ba clan tinker with some gadgets within his power.
"Alas~"
How many times does this fucking dog have?
Xu Chen sighed, slowly closed his eyes, enjoying the breeze and the bright moon, gently tapping the armrests of the recliner with his fingers, gently humming a song he was obsessed with and slowly fell asleep.
Chrysanthemum ancient sword and wine.
Being soaked in coffee into the noisy pavilion.
The foreigners worshiped the ancient moon at the Sun Altar.
The prosperous age of Kaiyuan is fascinating.
The wind never blows away the everlasting regret
Nostalgia can be penetrated by flowers
Snow cannot reflect mountains and rivers
The full moon cannot make ancient dreams come true
