...

The copper-smel blast furnace renovated by the kiln factory has been burning for five days.

From the beginning of the black smoke to the point where it is now slowly turning into a light yellow smoke.

The entire kiln factory was filled with a choking atmosphere.

Fortunately, the terrain at the foot of the mountain was wide open, and there were two heavy rainstorms in the middle. This breath was quickly blown away and had little impact on people.

Every morning and evening, Xu Chenlei would take a few glances, 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 are already considered experienced old kiln workers. They are more experienced in raising and maintaining the kiln fire temperature, and there is no need for any guidance or reminder from Xu Chen.

In fact, Xu Chen can't guide him now. He has never burned a kiln. He is just a simple theorist, commonly known as a verbal expert.

According to Xu Chen's estimate, it will take at least ten days to refine the copper.

Therefore, he could only wait except for morning and evening inspections.

There are more than 300 kilograms of copper ore in total, and the composition is relatively messy. The most are chalcopy ore, then the chalcopy ore, and there are some chalcopy ore, and there are even a few natural copper blocks and malachite with high purity.

Natural copper blocks, like dog-headed gold, have few stocks in nature and are very expensive minerals.

Malachite is a kind of companion organism produced by copper ore under high temperature and pressure during the ancient formation period. It has high ornamental value and is very similar to turquoise, but there is still a difference between the two.

Malachite is mainly green, while turquoise is mainly blue.

Both contain copper minerals, but they have great differences in chemical composition and structure, and their hardness and density are different.

Copper blocks, turquoise and malachite are collected by several tribes as gems and used as decorations. Ores are mainly used as pigments.

Based on the analysis of these copper-containing ores from the time they switched to this, Xu Chen concluded that there must be a large copper ore within a radius of hundreds of miles.

Perhaps it is in the valley where the Wu tribe lives.

Near the farthest distance of the Cang tribe, there should be a gold mine of not small size.

There is copper and gold. If the tribe can really develop, this is a Feng Shui treasure land for the founding of the country.

However, the first priority at the moment is to successfully smelter copper, then find two metals, lead and tin, and make the bronze out.

Only with a large number of sharp metal tools can humans truly have the ability to fight the sky and the earth.

The copper ore in front of me is very purity. According to his judgment and analysis, if all smelted out, you can get almost thirty kilograms of copper, but this is just a theoretical value. There is a lot of slag that cannot be cleaned. If you can get twenty kilograms, it will be a huge success.

What can I do with twenty kilograms? Make a copper hotpot?

Swords are definitely useless, why not just make a hammer?

Xu Chen was a little confused.

While observing and waiting, I took the time to use the clay to slowly make a few clay sheets for later use.

No matter what, being able to refine copper is the most meaningful thing he has done since time traveling through time.

The opening of this skill will have epoch-making significance for both himself and for the development of human civilization.

...

In the passageway to the courtyard, there is an extra rattan lounge chair.

This is a reward that Xu Chen gave himself after being inspired after finishing the cradle and crib.

In the southwest region, it is almost traditional to make lounge chairs with bamboo, and every household in the countryside has them.

In many places in Guizhou, even houses and furniture are made of bamboo.

He hasn't found bamboo yet, but there are many green vines on the mountain. This green vine is flexible and slender, and is very suitable for weaving things.

It's similar to the principle of making the last time the witch carries.

The skeleton of the recliner is tied with wooden sticks of varying lengths, and then the back of the lying chair is woven with green vines.

Although it was the first time to make a recliner, there were rattan carriages, cradles, and cribs to practice. Therefore, the details of this rattan woven recliner, except for the poor style and proportion of the style are very good.

Because the recliner is complex, it took him three days to complete it.

The tribe members didn't know what he made at first, and they just thought it was also a cradle or crib, or it was a vine sedan.

Until the recliner was completed, when Xu Chen lay down with satisfaction, all the tribesmen couldn't help but exclaim, and were once again completely impressed by his brain-burning magical creativity.

It is the hottest summer now. It is uncomfortable to sleep day and night. The room is small and sultry. Even if you only have a straw mat on the bed, it is still difficult to fall asleep. However, this kind of recliner is transparent from top to bottom. As long as there is a slight cool breeze, you can feel extremely cool.

Therefore, after this rattan chair was prepared, it instantly became the favorite of the entire tribe, no doubt about it.

Men, women, young and old scramble to lie on it, feeling the comfort and coolness brought by this magical recliner.

Xu Chen slept directly on the recliner during the past two days and nights. The monkey on the left and the little wolf on the right. Under the protection of two groups of divine beasts, two bundles of dried mugwort and hot water lily were lit in front of and behind his feet, bathing in the faint cool breeze blowing through the passage, and finally slept beautifully for two nights of cool sleep.

But as long as Xu Chen is not on the recliner, there are people lying on it at any time.

Everyone likes it, and Xu Chen is embarrassed to occupy it alone. It’s okay to say that the child is just driven away, but sometimes it’s a mother or a few older women, or a pregnant woman lying on it to rest, so he can only bear the pain and cut his nose and pinch his nose to find other places to rest.

In order not to cause family conflicts because of fighting for recliners, he simply brought two tools to build a row of rattan-woven cool beds against the wall on both sides of the gate passage.

The structure of the cold bed is simpler and more crude. It is to use wood as thick as an arm to build a row of wooden racks, with densely tied thinner wooden sticks half a foot apart, and then weave them next to each other with vines. Finally, there is a row of long rattan beds, about one meter five wide, and can sleep horizontally and vertically.

So since the cold bed was completed, the entrance passage became the favorite place for all tribesmen. A large group of women, children, elderly and weak people stayed on the cold bed and weaving cloth to chat and watch the children all day long. After the adult men and women working outside came back, they would sit on it and rest as soon as possible.

It’s really lively when I go to bed at night.

As long as it didn't rain, everyone was reluctant to go back to their room to sleep. A large group of old and young people squeezed into the cold bed, lit a few bunches of incense made of mugwort and spicy hot water grass, chatting, singing, willow flute, and leaves to brag for milk in the night. A few monkeys and two little wolves were hiking under the cold bed, and a group of children played hide-and-seek, which was simply lively.

At this time, Xu Chen always lies alone on his recliner, listening to the sounds of his tribesmen talking, chatting, playing and playing, looking at the river beaches, towering mountains in the distance, as well as the stars and moons or the dark night sky, enjoying a rare leisure, comfort and happiness in this primitive and barbaric era.

From time to time travel to the present, it has been almost a year in the blink of an eye.

It is already mid-May now, and last year I traveled through it in mid-June.

This year, the Ba people have changed a lot, but for him, the gains are not great, and he is still in a stand-alone state.

The Ba people are too small, and several nearby tribes are too far away. Because of the weak communication demand, the exchanges are almost half-cut.

Therefore, at present, in addition to clarifying the general situation near the tribe through two short exchange activities in Spring and Autumn, Xu Chen still has almost zero understanding of some places farther away.

Based on the current situation, the task of upgrading his tribe civilization will last for a long time.

To connect to the Internet, we must first solve the problem of food and clothing and transportation.

In addition, you must hold back your strength to send troops and equipment. Don’t just hang up after connecting online.

As a person who is not used to surviving people's faces, being strong is really strong. You must ensure your safety and life, and then consider the overall development of civilization of the tribe and the entire human race.

Everyone is satisfied with the current living conditions of the Ba tribe and respects him enough. He cannot sacrifice his life for the so-called kingdom of the Jiuzhou that unifies the Jiuzhou.

The most important thing is to be stable, not to mention that the powerful Wu tribe is still eyeing her.

The so-called stand-alone machine is not safe either. Before the time travel, the Time and Space Administration had already set up his living environment in advance. The Wu tribe was the first computer task he had to face before connecting to the Internet.

Only after the Wu tribe was dealt with, the game really began.

But he knew nothing about the current situation of the Wu tribe.

Since the Great Witch came back once in mid-March, there has been no news for two months.

In addition, after the big river rises, the river beaches on both sides of the river have been flooded, and the roads have been completely cut off.

In this ignorant and helpless state, he had no other way except to guard the Ba tribe and tinker with some gadgets within his ability.

"Oh~"

This fucking doggy era.

Xu Chen sighed, slowly closed his eyes, enjoying the breeze, reflecting the bright moon, gently tapping the armrest of the recliner, humming a song that he once was obsessed with slowly falling asleep.

Chrysanthemum ancient sword and wine.

Coffee soaked into the hustle and bustle pavilion.

The aliens worshipped the ancient moon in the sun altar.

The prosperous era of Kaiyuan is fascinating.

The wind cannot dispel long hatred

Flowers can't get rid of homesickness

Snow cannot reflect the mountains and rivers
