Burn a candle to know the night, and carve a candle to check the night.
Later, people carved time scales on candles made of specific materials and used them as timing tools. Such candles were called timing wax.
The Bai Ke incense of the Tang Dynasty was the pinnacle of the fire clock type timepieces. People in the Song Dynasty said, "The Hundred Ke incense is the most amazing in modern times. It is made by incense seals. Its writing is accurate to twelve o'clock, divided into one hundred quarters, and it burns for a whole day and night."
Has".
The so-called "Hundred-carved incense" refers to the spices made into the shape of seal characters and then subdivided into 100 scales. After the incense is burned, it will be exactly one day and night. The invention of this kind of object had a great influence on the fire clock type timekeeping in the Ming and Qing Dynasties.
had a profound impact.
Timepieces such as fire clocks have been used from ancient times to the Ming and Qing Dynasties. It can be said to be a very ancient way of timing.
However, the disadvantage of fire clock timers is that if there is an open flame, they will be seriously affected by changes in wind speed, resulting in inaccurate timing.
And the biggest disadvantage of the fire clock is that it requires someone to monitor it at all times.
"No wonder, since it is a fire bell, it must be watched over at all times, so when the Erba Godman was guarding the night for the Yellow Emperor, he also unlocked the wonders and astronomical observation skills..."
Looking at this huge three-fire disk of the sun, moon and stars, Yu Zai couldn't help but praise this spectacle. This was the wisdom of the ancient ancestors. They used the shadows of the burning fire to correspond to the positions of the stars in the sky, and then through observation and comparison at the observatory,
Can get the accurate time.
The Erba God-men are the most knowledgeable men of time and astronomical calendars in ancient times. Although they appear to be a bunch of fools, this fact cannot be denied.
"Then, the next thing to do is to rekindle the fire in the astrolabe. The fading fire has become smaller and smaller..."
The flames on the astrolabe were indeed much shorter. According to the description of Ye Zhong, the second eldest among the Erba gods, when they left, the reduction of the astrolabe flames was not very obvious.
Now it has become a lot shorter. If the fire is not ignited, the fire in the astrolabe may be extinguished.
"The branches of the three trees were cut down, and the leaves of Meteor were reduced to ashes. Bi Fang's fire burned them all, leaving only the bare stumps. We had no choice."
Ye Bo sighed and looked at Yu Zai expectantly.
I hope Yandi's fire can temporarily replace it.
Ruanzai thought carefully and took two steps to the edge of the astrolabe. On the other side, the little yellow chicken wearing a bamboo hat began to run around the three plates.
Guzi felt very comfortable staying next to the flames of Sanpan!
It’s like staying next to Mama Zai!
Guzi flapped his wings, flew up hard, and then landed on the sun disk. The strange runes could not be understood by Guzi, but it did not prevent the little yellow chicken from raising its paws and starting to pace step by step according to the intervals between the runes.
stand up.
"Gu? Gu? Gu!"
The other party.
Yuzai stretched out her hand and began to try to make the weakened flame burn again.
As a result, intense light and flames appeared in the palm of the hand, and in the wilderness, the central area where the three pans were located was illuminated by this firelight. However, when the light fell on the ground, it was somewhat scattered, unlike the original pillar of fire.
In comparison, the fire in Yu Zai's hand made the shadow of the fire pillar mottled and broken.
The "accumulating Yang Qi" rose from the flame in Yu Zai's palm. The sun-centered Qi absorbed last summer, at this time, with the help of the Qi Refiner, was like adding wind to the fire.
The weak flame began to pull up.
"Yes, yes! I can see the effect!"
The Erba gods were very happy, and Yuzai's eyes lit up, and he began to increase the output, and the flames lived up to expectations. The totem of the sun was fully displayed, with huge roars and winds, and the heat of the sun rolled upwards, and the flames were slowly
It is getting higher and brighter.
"Quick, quick, quick! Get on the coals!"
The Erba gods immediately hurriedly moved to their houses to move charcoal. The huge coal mine made Yu Zai's eyes full of black.
The Erba gods told Yuzai that somewhere in the wilderness of Bizhi, there were burning coals that would never burn out. That place was not far from the three stone formations in front of them.
According to the descriptions of the Erba gods, what they saw should be spontaneously igniting coal seams.
There are many reasons for the spontaneous combustion of coal seams. However, the flames in the Biyi wilderness were ignited more than 200 years ago, so it should be the Erba gods who ignited the flames during the construction and mining process. This kind of burning behavior caused the wilderness to burn.
Part of the coal seam below started to catch fire.
A large amount of charcoal was moved and sent to the ignition area in the center of the astrolabe, so the sacrificial fire, which was still a little empty, suddenly became brighter and more solid!
But Yuzai felt very strenuous.
The power of the sun totem was continuously transported in, but the burning height of the sacrificial sparks was not raised much.
At this time, Yu Zai retracted his hand appropriately, the heat of Jiyang subsided, the tall flames burned brightly, and then——
stopped.
The Erba gods were sweating on their foreheads, staring and gritting their teeth!
"The flames were raised high again, and then charcoal was used to maintain them. As a result, the fire stopped moving after the initial surprise."
Everyone was a little dumbfounded, because the Erba gods had seen the method from the fire-wearing country's sacrifices, but they didn't expect that something went wrong when they put it on their own three plates.
"It is true that the burning of flame requires a medium, and there is nothing wrong with the fact that coals are the medium."
"But the branches of the three trees are powerful burning media, corresponding to the meteors in the sky, and the coal is just ordinary coal."
"It is indeed maintainable, but..."
Yu Zai began to think that some things cannot be judged by normal common sense, such as totem flints. In fact, it is similar to the current situation, because not all flints can bear the tribal totems, and special flints are required.
, this kind of flint is "flint".
Boiling water... Nuclear reactions also boil water, but you can't say that when I use briquettes to boil water at home, I am creating a nuclear reactor.
Substitutes are, after all, substitutes.
Then this is interesting. Your explorer unit discovered a village. From the village, an old man taught you "nuclear technology"...
"look."
Dayi pointed at the astrolabe. Although the position of the flame had stopped, the burning mass had obviously begun to solidify, and it no longer looked like a virtual fire.
"The power of the sun totem and the fire of Emperor Yan are still effective."
Dayi smiled: "Three trees grow on the bank of Chishui River. Emperor Yan once lived here. It is said that he planted the three trees."
"The three trees are the fire of meteors. The essence of fire is blazing gas. Spark fire and sun fire have something in common. It's just that the branches of the three trees can burst out the flames of meteors. They are excellent burning things.
The burning thing that bears the totem of the sun is not."
Yu Zai stared at the fire and used the "big fire" witchcraft again.
"Coal, oxygen, fire..."
The sun totem regained its power, and Yuzai made a "blessing" movement, and the totem and bloodline began to work.
"It is correct to use coal to extend the flame burning. The only shortcoming is that there is no advanced combustion medium equivalent to three trees. Coal alone cannot reach the burning height of three trees. It can only maintain but not grow."
At this time, a small figure was walking on the three disks, walking from the sun disk to the moon disk, and from the moon disk to the astrolabe. Guzi watched Yuzai rekindle the fire...
With a snap, Guzi fell in.
Then, the originally weak flame suddenly boiled!
The sky-high light illuminated the surroundings, and the flames rushed up and burned fiercely. In an instant, they were almost close to the original peak of the fire!
