Burn candles to know the night, and engrave candles to check the change.

Later, people carved time scales on candles of specific materials as a tool for keeping time, and this kind of candle was called timing wax.

The Tang Dynasty's 100 carved incense, belongs to the pinnacle of the fire clock class timer, the Song people have a saying, "100 carved incense, the modern Shang Qi people make incense seals, its text is 12 Chen, divided into 100 moments, where to burn a day and night."

The so-called "100 incense" refers to the fact that the spice is made into the shape of a seal and then subdivided into 100 scales. It was exactly day and night after the incense was burned. The invention of this object had a profound impact on the fire clock timekeeping in the later Ming and Qing dynasties.

Fire clocks and other timers, which have been used from ancient times to the Ming and Qing dynasties, can be said to be a very ancient way of timekeeping.

However, the disadvantage of fire clock timers is that if there is an open flame, it will be seriously affected by the change of wind speed, resulting in inaccurate timing.

And the biggest disadvantage of the fire clock is that it needs to be watched by someone at all times.

"No wonder, since it is a fire clock, it must be taken care of at all times, so when the two eight gods were at night for the Yellow Emperor, they unlocked the wonder and astronomical observation skills by the way...."

Fei Zai looked at this huge sun, moon and star three fire disks, and couldn't help but praise this wonder, this is the wisdom of the ancient ancestors, with the shadow of the fire burning and the position of the stars in the sky corresponding, and then through the observation and comparison of the observatory, you can get the accurate time.

The 28 gods were the most knowledgeable of time and astronomical calendars in ancient times, and although their outward manifestations were a group of foolish criticisms, it is indeed undeniable about this.

"Then, the next thing to do is to rekindle the fire of the astrolabe, and the fading fire has become smaller and smaller....."

The flames on the astrolabe are indeed much shorter, according to the description of Ye Zhong, the second eldest of the two gods, when they left, the decrease in the flames of the astrolabe was not very obvious.

Now it is a lot shorter, and if it is not lit, then the fire of the astrolabe will probably be extinguished.

"The branches of the three trees have been cut off, the leaves of the meteor have been reduced to ashes, and the torches of Bi Fang have burned out there, and only the bare stumps remain, and there is nothing we can do. ”

Ye Bo sighed and looked at Yu Zai expectantly.

I hope that Emperor Yan's fire can be replaced for the time being.

Yu Zai thought carefully for a while, took two steps on the side of the astrolabe, and on the other side, the little yellow chicken wearing a hat began to run around the three disks.

Goo feels comfortable staying by the flame of the three plates!

It's like staying by Ma Mazai's side!

Goo flapped his wings, flew up hard, and then landed on the top of the sun disk, the strange rune Goo couldn't read, but it didn't prevent the little yellow chicken from raising his paws and starting to pace step by step according to the rune intervals.

"Goo, goo, goo!"

The other party.

Stretching out his hand, [5200 www.bqg5200.biz] began to try to rekindle the weakened flame.

So, the fierce light and flames appeared in the palm of the hand, on the wilderness of the wings, and the central area where the three disks were located, were illuminated by this firelight, but when those lights fell on the ground, some of them were scattered, compared with the original pillar of fire, the fire in the hand of Yu Zai made the shadow of the pillar of fire mottled and shattered by the thorns.

On the flame in the palm of Yu Zai's hand, the "Yang Qi" rises, and the mid-day qi absorbed last summer, at this time, with the help of the means of the Qi Refiner, it is like adding fire to the wind.

The weakened flames began to rise upward.

"There you have it, there you have it!

The two eight gods were very happy, Yu Zai's eyes also lit up, and began to continue to increase the output, and the flame also lived up to expectations, the totem of the sun was fully exerted, the huge roar and wind, accompanied by the heat of the sun, rolled upward, the flame was slowly raised, and it was constantly brightening.

"Hurry up, hurry up, get on the coals!"

The Twenty-Eight Gods suddenly hurriedly went to their respective houses to move coals, and the huge coal mine made Yu Zai's eyes full of black.

The 28 gods told Yu Zai that in the wilderness of Biyi, there was an unquenchable coal, and that place was not far from the current Sanpan Stonehenge.

According to the description of the 28 gods, what they saw should be a spontaneously combustible coal seam.

There are many reasons for the spontaneous combustion of the coal seam, but since the flame in the Biyi Wilderness was burned more than 200 years ago, it should be that the 28 gods ignited the flame in the process of building and picking up the ore, and this burning behavior caused some of the coal seams under the field to start to catch fire.

A large amount of coals were brought in and sent to the ignition area in the center of the astrolabe, so that the sacrificial fire, which was still a little empty, suddenly became brighter and more solid!

But Yu Zai felt very struggling.

The power of the sun totem was continuously transported in, but what was felt was that the height of the sacrificial spark did not rise too high.

Yu Zai withdrew his hand appropriately at this time, the heat of the accumulated sun subsided, the tall flames burned, and then—

Stopped.

The twenty-eight gods were sweating on their foreheads, staring at them and gritting their teeth!

"Raise the flame again, and then use coals to maintain it, and now, after the initial surprise, the fire does not move. ”

Everyone was a little dumbfounded, because the methods that the Twenty-Eight Gods had seen from the sacrifice of the Fire Disgusting Country, but they didn't expect that there was a problem on their own three plates.

"There is indeed nothing wrong with the burning of a flame that requires a medium, and there is nothing wrong with the coals of fire being a medium. ”

"But the branches of the three trees are powerful combustion mediums, corresponding to meteors in the sky, and coal is just ordinary coal. ”

"It's really maintainable, it's just ....."

Yu Zai began to ponder, some things, can not be judged by normal common sense, just like the flint of the totem, in fact, it is similar to the current situation, because not all flint can carry the totem of the tribe, there must be a special flint, this flint is "flint".

Boil water..... Nuclear reactions are also boiling water, but you can't say that I am making a nuclear reactor by boiling water with briquettes at home.

A substitute is a substitute after all.

Then this is interesting, your explorer unit found a village, and from the village, there are old people who teach you "nuclear technology......

"Look. ”

Dayi pointed to the astrolabe, and although the position of the flame had stopped, the mass of the burning had obviously begun to solidify, not like a false fire.

"The power of the Sun Totem, the Fire of the Yan Emperor, is still effective. ”

Dayi smiled: "Three trees grow on the shore of Chishui, there is a Yan Emperor who once lived here, and it is said that the three trees were planted by him. ”

"The three trees are the fire of a meteor, the essence of the fire is the burning gas, the spark and the sun fire, there is something in common, but the branches of the three trees themselves can burst out the flame of the meteor, which is an excellent burning thing, but the burning thing that carries the sun totem does not. ”

Yu Zai stared at the fire and once again performed the witchcraft of "fire".

"Coal, Oxygen, Fire ......"

The sun totem regained its strength, and Yu Zai made a "wish" action, so the totem and the blood began to work.

"It is correct to use coal to prolong the burning of the flame, but what is missing is that there is no advanced combustion medium equivalent to three trees, and coal alone cannot reach the height of the burning of three trees, and can only maintain but not grow. ”

At this time, a small figure was pacing on the three disks, walking from the sun to the moon, from the moon to the astrolabe......

With a snap, Goo fell in.

Then, the originally weakened flame suddenly boiled!

The sky-high light illuminated the surroundings, and the flames rushed up, blazing, and in an instant they were almost close to the original fire apex!
