"If there is an instrument for measuring the years of daylight, then there must be the same thing for measuring the years of night."
Every time Yi saw the sundial, he would think in his mind that there must be something corresponding to the sundial. The sun gave birth to the day and the moon illuminated the night, but the moon did not necessarily appear as often as the sun.
It is measured using stars.
"How do you rely on the stars to determine the years and hours?"
Yu Zai was very curious. Regarding the stargazing technique in ancient times, later generations would not be able to learn it without any skills. However, there are sixteen gods who are good at watching stars at night. How could they not ask for help at this time?
And they actually have the wonder "Stonehenge"!
Unlock the technological calendar, +5 faith, goodbye.
This thing seems to buy a great man!
In fact, it is said to be Stonehenge, but it is actually the big stone house where the Erba gods live during the day. Because they are arranged around the sacrificial flames according to a certain pattern, when the Erba gods recounted their stories, Yu Zai would think of Stonehenge.
stuff.
Ye Bo began to tell Yu Zai about their methods.
"What the earth carries includes everything between the upper, lower, southeast, northwest and Liuhe. Within the four seas, there are also the sun and the moon shining, there are big and small stars rising in the east and setting in the west, there are four seasons of spring, summer, autumn and winter to record the seasons, and there are also the twelve Taisui.
The annual cycle is aligned with the natural time.”
"The stars in the sky can move, like right now."
Ye Bo raised his head, searched in the sky, saw a star, pointed at the star, and told the time, it was probably half past two in the middle of the night.
This is similar to the method used by Yu Zai in the past to judge the approximate time by watching the movement of stars in the sky when exploring geology, such as exiting and retreating.
However, the ancients looked at the stars to tell the time, not just the approximate time, but also the "celestial equator" and the "permanent circle". After listening to Yebo's story, Yuzai was a little confused. Looking at the stars is actually
If you ask a university question, most people really can't do it.
The stargazing skills of the Erba gods are even more powerful than those of Uncle Xi and others, but such powerful stargazing cannot accurately correct the time, so sacrificial fire is needed. If there is no sacrificial fire, according to the Erba gods
Humanly speaking, the stars move every day, and they move slower than the day before.
Yu Zai disagreed with this statement. Of course, it was better not to say this. After all, when it came to stargazing, compared to them, he was really a three-legged cat.
"The night is governed by the stars, the big moon, and the rooster. When the big moon rises in the east, the Chang Geng star appears in the western sky."
No matter what the world is about, at least some of the knowledge points in the stargazing method explained by Erba God are very different from what Yu Zai knew in the past.
"One-third of the sacrificial fire has died out, and we cannot clearly see how much time has slowed down. The shadows have also disappeared, and all living things in the world are a little frightened."
The Erba gods still hoped that Ruanzai could go with them, but at this time, Ruanzai thought of something that could be used to keep time at night.
That's night leakage.
As the saying goes, "When the night is gone, the sky will be bright."
But to be honest, this thing is difficult to make. Compared with the sundial, Yu Zai is not sure about the specific method of making the night clock. This thing relies on the delay of dripping water for accurate time calculation. Maybe archaeologists can know this.
How to make toys.
But for Yuanzai, this is indeed a very unfamiliar thing, just like the moondial that I first thought about. This thing sounds like it is made according to the moon? But in fact, the moondial is comparable
The sundial appeared more than a thousand years later, and it was also very difficult to make.
After listening to the ancient stargazing techniques of the Erba gods, Yu Zai knew that this was definitely a good thing.
But the Erba gods began to complain.
"The sundial is a good thing, but it still has shortcomings!"
"This is just delaying the time!"
"If Emperor Yan's fire can rekindle in the wilderness of Biyi"
"Yes, yes, come with us!"
"Although we can't give you three tree branches, we can give you other things!"
"Yeah!"
The gods began to respond noisily, and Yuanzai asked with a smile: "Yes, the journey is long, and we can't just agree to strangers. We don't know you, and we don't know Lingnan even more, so we just went there rashly.
If I die, what will happen to the tribe?"
The gods said: "We will drive the wind and rain to clear the way for you!"
"We can call upon all the beasts to find the way for you!"
"If there is a cliff, we will jump over it with you in our arms!"
"If there is a big river, we will put you on our shoulders!"
"If there is a strong wind, we will form a wall to block you!"
"If there is an earthquake, we will run with you!"
The gods spoke sincerely, and Yu Zai asked again: "If I go with you, then what are the good things you talk about?"
Ye Bo said: "If you help us light the sacrificial fire, we can give you charcoal, which is a good thing for fire wizards to practice."
Yu Zai: "Fire coal?"
Is it the kind of charcoal you understand?
Ye Bo described it. In addition to normal charcoal, he specifically mentioned that the Fire-Tired Kingdom was rich in a kind of black stone that burned as hot as firewood. There used to be fire wizards there who used it.
This kind of black stone practice.
"This thing, in some places in the north, seemed to be called Shi Nie more than a hundred years ago."
As soon as Ye Bo said these words, Su Zai was shocked! Then he immediately said to Chi Songzi:
"I think I should take a long trip!"
Chisongzi was also startled by the sudden change in face of Zuzai, and Zuzai said: "Master, even if it is not a fire wizard's cultivation treasure,"
That’s probably “coal”!
It has been said that Shi Nie is the same thing, Shi Nie is a name for coal!
It’s not that there is no coal in the south, but there is very little, and it cannot be used on a large scale. It is naturally far inferior to the north and the northwest wilderness, but the people of the Fire-weary people and the Erba gods actually have coal.
To be honest, the performance of coal in iron smelting is actually not as good as that of charcoal, but the consumption cost of charcoal is higher than that of coal. Large-scale felling of trees and the speed of planting trees are far slower than the consumption, although there was no such thing in primitive times.
There are so many concerns, but the role of coal is not just for smelting.
Just this thing, if the deal is done, a large number of people can be brought back, or even a coal transportation route can be built, it will be worth abandoning the spring plowing this year and going out to purchase goods!
Dayi said to Chisongzi: "I didn't expect that there are stone nirvana in the south, but can this thing be used as charcoal to make a fire?"
"It is said that people in the Fire-Tired Kingdom like to eat these things very much. Because they eat these coals, they can spit out fire from their mouths. It turns out that these coals are stone nirvana."
Ruan Zai discussed with Erba Shenren that he could bring a pile of coals from Bizhiye back to Ruan Zai, but Ruan Zai had never thought about using coal to practice as an energy source.
, let’s take it slow first!
"I doubt it now"
Yuzai muttered.
"The reason why there are endless fires in the wilderness of Bizhi is because there are coal mines down there!"
