At the waterfall base, two days have passed since Ye Qiong entered the Shimen space in the waterfall cave...
Ye Qiong has been spending the past two days in the laboratory at Waterfall Base.
After adding a wooden house, the laboratory has become somewhat larger. Ye Qiong's main research now is tungsten ore and the liquid obtained from the green pool.
Some of the tungsten ore was kept in the laboratory, and the other taken from the waterfall was directly given to Kuang Baizhi's five apprentices.
The people left at the waterfall base by Kuang Baichi this time were the first batch of people to be accepted as apprentices by Kuang Baichi, and they had already learned a lot of skills.
However, in order to prevent waste, Ye Qiong did not take much. Quan thought it was for them to practice and see if they could make black weapons and armor like those on the right side of the Waterfall Cave.
With the availability of coal, the refining of tungsten ore becomes much more convenient.
Controlling it at about 1,000 degrees for two hours, you can dissolve 99% of the calcium orthosilicate in the tungsten ore, and then soak it in water with a temperature above 80 degrees to get sodium tungstate and some infusible materials. Residue.
During the dissolution process, the materials required for forging weapons are added, and after controlling the proportions, a simple alloy metal weapon comes out. After a series of beatings, the impurities inside are knocked out, and after shaping and sharpening, the final step is Weapons used by warriors.
Different material ratios will result in different toughness and hardness of the weapons created. This ratio is the difference between a forging master and a novice.
Kuang Baichi spent the first half of his life studying these things, but he was also standing on the shoulders of his predecessors.
There were gentle clanging sounds coming from the laboratory at the Waterfall Base.
Ye Qiong was leaning on a wooden chair, and his right index finger was tapping the wooden table gently.
On the wooden table, there are several bottles of different sizes, all made of ceramics, containing several liquids.
The palm of Ye Qiong's left hand was not empty now, but had an extra light yellow particle, about the size of a grain of rice.
This is also the result of Ye Qiong's efforts over the past two days.
The millet grain in your hand is not gold or iron, but copper!
It is extracted from those dark green liquids, although it is only the size of rice grains, but the content is already very high.
What I never expected was that the liquid in the pool contained such a high copper content and was stored in it.
Originally, Ye Qiong always thought that the green viscous liquid was just some wastewater used by the ancestors of the Naning tribe when making weapons. In Kuang Baichi's blacksmith shop, there is a lot of wastewater for quenching iron, which is concentrated together every day. After that, it will also turn green.
But the wastewater used in the blacksmith shop definitely contains no copper element.
As for extracting the copper element from these liquids, it is relatively simple. In the prehistoric era of the earth, large-scale bronze vessels were born. The birth of any large-sized bronze vessel can cause a sensation in the archaeological world. If If there are words on it, the value of the bronze will be higher for each additional word.
To extract this rice grain-sized copper block, Ye Qiong used wet smelting method. Copper is already liquid and can be extracted directly without any auxiliary equipment.
As for bile vitriol and bile water, the central tribe has a lot of medicinal materials in its library, most of which are obtained from the jute tribe. For this kind of light blue crystal, many tribes like to collect it when collecting supplies. Later, Gradually, I discovered that drinking this stuff in water can treat some oral diseases, and it gradually became a medicinal material.
Now every peripheral base has a room dedicated to storing medicinal materials, which are used to treat some common diseases for soldiers and are also combat preparation materials. Therefore, although the base is not big, it still has a complete range of medicinal materials.
Ye Qiong is now holding the copper block the size of a rice grain in one hand and tapping it gently on the wooden table with the other hand, just to sum up the logical problems.
It's about whether the ancestors of the Na Ning tribe refined copper.
If you have the guts, refining copper is easy, but it remains to be seen whether they had the ability to do so more than three thousand years ago.
Being able to extract copper is enough to prove that the wastewater in the pool is not the wastewater for forging weapons. If it is not used to extract copper, Ye Qiong must think about what the water in that pool is used for.
"Bang bang bang..."
Thoughts were flying. In Ye Qiong's mind, various trivial information about the Na Ning tribe and the ancestors of the Na Ning tribe were being spliced together. Ye Qiong tried hard to connect the information together, but always found that there were a few missing people who could. The connecting point that connects it.
…
Canyon base!
Kuang Beili was leading a few soldiers to hunt scavengers in the periphery.
Entering the late winter, there is no food on the ground.
Mother Earth, perhaps could not bear to let the creatures above the snow become extinct, so this kind of vegetation was born.
That’s edelweiss!
After a long early winter and mid-winter, in some areas with relatively thin snow, those white seedlings broke through the snow layer and worked hard to absorb the energy released by the stars.
Some omnivorous beasts that had turned over the ground long ago can finally relax a little more. For them, it is much easier to find edelweiss on the ground than to eat tree roots from beneath the ground.
Some scavengers will eat edelweiss when there is no food.
For some small tribes, edelweiss has also become their hope to persist until spring.
At this time, some tribes that are short of food must send teams to leave the tribe to search for edelweiss. Larger tribes still have the ability to continue hunting Warcraft and Scavengers.
But for a small tribe that can only arrange for thirty to fifty people, or even a dozen people to go out, avoiding the monsters and scavengers and looking for edelweiss seems to be their only hope to persist until the beginning of spring.
Bringing the collected edelweiss back to the tribe, boiling it with snow into soup, and distributing it to the tribe members can prevent the tribe from developing into the most terrifying end of the world.
The soldiers in the canyon base naturally don't need to look for edelweiss to satisfy their hunger, nor do they need to hunt monsters and scavengers. Now Kuang Beili and the soldiers came out, completely free in the canyon base...
Fishing, exercising, and basking in the sun are basically the daily lives of the soldiers in the canyon base. It is leisurely and comfortable in the days when there are no attacks by beasts or crazy crowds.
Several warriors who had their turn to rest gathered together, carrying coal braziers, and sat down in the icy river channel of the canyon. They put fishing rods into the ice holes that were smashed out, and ice would appear from time to time. The fish below the domain are hooked.
After the fresh fish is hooked, the soldiers will pull out their daggers, scrape off the fish scales randomly, insert a wooden root in the middle, and spray it on the charcoal fire. After a while, the snowy devil wolf sitting next to him will roar. Stayed.
As a warm winter weapon, coal gave soldiers endless fun in the wild.
"Chirp! Chirp! Chirp!"
Just as the two waves of warriors gathered together to enjoy the warm days under the stars in winter in the icy rivers of the canyon, a rapid whistle broke the silence!
