A few days later, Likui left. He had seen too much in the south. He promised Suzai that when he returned this time, he would preach the praises of Hongzhou in the waves of the Northeast Sea and among the mountains and tribes. name.
He said that he might come back, and he would consider the invitation from Zanzai to live here from Pogu Mountain. Then, since it is a land where he might live in the future, there is no need to rush to stay at this time.
Carrying the goods exchanged from Hongzhou and leaving was something that would shock the world if word spread.
In the future, he can also learn from Dayi and tell others "I have a friend" everywhere...
Likui left a lot of goods, and he also left the location where the goods were obtained. He stayed here for many days, and Yuzai called a bunch of people to help record the goods.
The origin of these things, ores, tribal locations, strange animals, crops, geological environment, natural wonders...
In this way, everything is completely recorded, and a geological manual can be compiled here!
Yu Zai laughed in her heart!
Tell those weird names to Hanman, Shuhai, Wenming, "Man and Nature", "National Geographic" and the like...
In this case, no one will try to force me to name "The Classic of Mountains and Seas"!
After Li Kui left, he left so many records and goods that he couldn't finish counting them in a while, so Juzai searched again for the ore classification to see if there was any that could be used for various experiments in the future. mineral.
For example, scheelite, which often coexists with cassiterite, beryl, tourmaline, apatite, diopside, Fushanite, tremolite, tin, molybdenum, bismuth and other ores... In Sichuan, Gansu, and Hunan, There are branches in Yunnan and other places.
This thing can be used in many places, but the most famous one is used to make tungsten wire in light bulbs.
Before the appearance of tungsten filament, bamboo fiber was used. After using a vacuum pump to form a vacuum environment inside the bulb glass, the electricity was then turned on... Of course, the bamboo filament would burn out soon...
In fact, Yu Zai was planning to wait for the flood to recede before sending manpower to other places for mining. This era belonged to the ignorant period of the mining industry. There were many places in the Classic of Mountains and Seas where the ore was almost exposed and everywhere.
So there is no need to risk your life for underground or deep mountain mining... When ancient people went into deep mines, children were often needed because the mines were small and only children could enter and exit at will.
As for how future generations will mine, by that time, the corresponding technology would have already appeared.
Of course, besides scheelite, there was another thing that caught Ruanzai a little off guard.
uranium!
This familiar touch is still the same as before, and based on many years of experience as a geologist, I can immediately tell that the "quality" of this piece of uranium ore is very good!
Copper uranium mica!
The goods have been received and are genuine!
Yuzai felt resonance, meeting each other across 4,300 years, and in this era, it is very interesting to say that uranium compounds were used in the early days to color pottery and porcelain...
The pottery in your home may have been the color of atomic bombs in ancient times.
Yu Zai looked at this piece of uranium ore, and a bold idea came to his mind...
…
The next few topics that Yu Zai was going to prepare were relatively complex and required a high level of knowledge, so before Li Kui came back, Yu Zai did not continue to work, but stayed in the office.
Light, heat, electricity, sound, magnetism.
It can be said that if these five topics are illuminated, then the pace of social production development will take a big step forward.
Although among them, relying on the wizard's ability, there are many things that have been mastered, such as light is Gugu, heat is a few Zhurong, electricity is the welder's cloud neutron, sound is the wind beast, magnetism... .Just bring in Tieniu or Teacher Guangchengzi (Jinde) and give the cloud neutrons a shot.
However, social development cannot rely solely on wizards and qigong practitioners. Progress is the progress of the masses. After having enough food and clothing, we should have higher pursuits.
These five topics were moved to the explosion factory. Several big bombers were very interested in the research direction of the new topic, especially Huang Di, who fell in love with the subject of "electricity" at a glance.
Yu Zai thought that in optical technology, the only technological items that could be pointed out in the primitive era seemed to be microscopes, so it would be a good topic to start with electricity, because the other four all require electricity as energy.
After all, if society wants to develop, we cannot treat cloud neutrons as batteries.
The idea of putting Gugu in a tractor was outrageous enough before.
"Use glass, lead plate, sulfuric acid, copper, aluminum, leather..."
The structure of the battery is not difficult. Yan Zai did an experiment in an explosion factory. The lead plates in the glassware were immersed in sulfuric acid...
Of course, there are many types of ancient batteries. For example, the famous Baghdad battery is made of pottery and copper, and manganese batteries are not difficult to make...
Huang Di charged the battery, and after a while, Huang Di asked Huang Di to pick up the metal wire. At this time, Huang Di's hair suddenly stood up.
"How do you feel, Teacher Yun Zhongzi?"
Huang Di's eyes shined brightly at this time!
Oh oh oh!
Thor recharges!
Huangdi(??Battery 100%)
"I feel great. If this thing wasn't so easy to break, I should have brought two more cans with me!"
Huang Di expressed his inner thoughts. Unexpectedly, the dawn of electrical energy came from the sulfuric acid he randomly burned in the furnace.
Next, Yuzai tried another "toy".
It was a copper ball. This hollow ball was connected to a sealed pot filled with water through two hollow tubes...
Heat the bottom of the pot and the water begins to boil...
"Woo!"
It seemed that everyone heard this sound, and then saw violent steam spurting out of the two pipes!
The ball is starting to spin!
"This is power. The power of heaven and earth is everywhere. Water and fire are combined. That's it. I once used this power to burn the enemy..."
Yu Zai was talking about his past experiences, but Yu Pan suddenly realized what he was doing!
"Wu Yuan is just a ball."
Yu Zai: "?"
Apan, you are itchy again, right?
Yuzai said, "Yuanpan, I just like to hang you on a tree and beat you until the tree falls and you are still alive!"
After Yan Pan executed a set of combos, Yan Zai continued to tell everyone that in addition to steam power, he also needed to make simple generators. The source of Hongzhou's semi-mechanical production power now comes from water conservancy, such as large
Spinning wheels and iron smelting water rows, large waterwheels and the like...
The creation of a hydraulic generator will provide an additional source of energy in the future, and the significance it represents is very important...
The dawn of the tractor era!
Yu Zai: "My dream is to build a tractor in this era!"
But before that, regarding the uranium ore...
Yuzai left the explosion factory and found Gugu playing cards near the textile factory.
