Honghuang, I am engaged in science and technology in the Wuzu

“Hiroshi,?” On the way back, Feng looked at the dead branch that Fang Hao brought back and asked curiously.

“I’m preparing for a fire.” Fang Hao said.

“Oh, fire?” Feng asked curiously.

“Fire is an indispensable thing that can shine, and with fire we can bake food, illuminate, heat, smelt, etc., and our lives will enter the stage of civilization, and with this we can make it.” Fang Hao explained.

He is not afraid that the little girl will not understand, the Terrans of this era are not ordinary, the wisdom is amazing, inheriting the divinity from Nuwa, the IQ is extremely high, the eyes are not forgotten, the understanding and understanding are super strong, but the knowledge is not as rich as modern people.

“Feng” was the first Terran that Fang Hao was preparing to cultivate, and during this time, he gave “Feng” a lot of knowledge.

Fang Hao was also not afraid that his source of knowledge would be exposed, because it was not surprising that the creatures of this era were born to know a little, and the prophet was not the best example, so Fang Hao did not have a little pressure.

After coming to the cave, Fang Hao began to prepare tools for drilling wood for fire.

Drilling wood for fire is based on the principle of friction heat generation, wood raw materials themselves are rough, in the friction, friction will produce heat, plus wood itself is flammable, so it will make fire.

Although modern people seem to have simple principles, on Earth, the question of what flame is has been pondered for thousands of years, and there is no reliable explanation until modern times.

Wisdom is precious not because of how complex it is, but because it can break the limits of thinking.

The drill wood fire tool consists of two parts, one is the drilling fire plate, and the other is the drill rod and bow wood, and the two can be combined to take out the fire.

Drilling board to choose dry easy to burn wood, drilling rod to moderate thickness, in the fire has a certain skill, not just by brute force can drill out of the fire, just happened when Mars is invisible, in order to make the invisible Mars into a vigorous flame must have a medium, that is, flammable velvet, plantain root fiber, kapok wool, etc. ignition, but also lose no time in oxygen delivery, in order to achieve the purpose of fire.

The drill pipe and bow wood are easy to manufacture, Fang Hao quickly manufactured, only need to press the bow wood down to make the drill pipe inertia rotation, so that the continuous cycle rotation, the lost kinetic energy is all converted into heat energy generated by the friction between the drill pipe and the drill plate.

First punch a small hole in the top of the drill plate, and then put the drill pipe into the small hole, Fang Hao began to press down on the bow wood, and the drill pipe began to rotate.

Soon after, the drill board began to emit a little green smoke, and the “phoenix” on the side was very excited after seeing the green smoke.

“It’s on fire!”

Soon after, a trace of sparks sputtered out, Fang Hao quickly blew air on the friction of the drill pipe, and gradually Mars became obvious, put the velvet into the friction and slowly blew air, and finally, the first artificially created flame rose up.

There is no celestial change, there is no fire merit, the universe is still that universe, and the rules of the universe will not change because of the discovery of an ant.

Fang Hao was telling Feng about drilling wood for fire, when a group of people came.

“Hiroshi, this?” The tribal prophet “forgiveness” came over and asked in amazement.

She was followed by many people from the tribe, all with a surprised expression.

“It’s a flame that has a great use to bake food and prevent disease.” Fang Hao said with a smile.

“Grilled food?” Even though the prophet was the first human beings created by Nuwa and had an extremely high IQ, she could not understand the word roasting.

“It’s about making the food tastier.” Fang Hao explained.

“Oh, got it, try?” Excuse asked.

“Of course you can!” Fang Hao said with a smile, and then began to prepare the barbecue.

Today’s ambient air is very oxygenated, at least 30%, so food decays very quickly, and those lambs will stink if they are not eaten today.

At the same time, because the oxygen content is too high, the creatures in this world are particularly huge, such as ants are the size of watermelons, which is very terrifying.

As for the Terrans, it is much worse, more manifested in wisdom, so it is difficult to move in this flood era.

Without Fang Hao’s hand, the little girl directly began to drill wood, and soon after, a trace of sparks appeared on the drill board, and then the little girl carefully blew Mars, and the flames slowly burned.

Then Fang Hao added dry firewood to the flame, and gradually, the bonfire burned violently, making a crackling small crackling sound, and a long-lost warmth appeared in the cave.

The Redstone tribe first appeared a bonfire, and when the bonfire first appeared, there were a lot of jokes, a Redstone tribe Terran tried to touch the flame, and was scalded and wow.

But at this moment, everyone’s mind was not in the flame, but on the roast meat that smelled of meat, and I saw Fang Hao sticking a giant mutton with a wooden stick, roasting it next to the flame, making a moisturizing sound, and a drop of oil dripped down, obviously the mutton was very fat.

“Boom!” Everyone couldn’t help but swallow their saliva, it was too fragrant.

“Oh! Oh! Oh! The Terrans cheered loudly.

Not only the Terrans, but also the people of the Wu Race were extremely impressed, because Fang Hao raised flames without relying on spells, and they only felt that a fog in their hearts had completely dissipated.

What exactly this fog is, no one knows.

“Hiroshi, how did you know that drilling wood can raise flames? Think of a spell flame roast is different. While eating the cooked meat in his hand, Riverside asked curiously.

“This is the content of the inheritance of the Avenue of Science and Technology, and the process of discovering fire is the Avenue of Science and Technology.” Fang Hao explained.

“But I still can’t understand it.” Riverside thought for a while and tangled.

“What is the flame, this is the topic I gave you today, you need to dig the truth inside, remember that this is not the rule of heaven and earth, but the truth of heaven and earth, the truth of heaven and earth is the road of science and technology, if you understand, tell me.” Fang Hao said.

“I see, I’ll figure it out.” Riverside nodded and began to ponder.

Fang Hao looked at the pondering riverside and sighed, how can technology be so easy, every knowledge point of science and technology is the experience of thousands of people summed up together, he is now just teaching the riverside how to think.

Regarding the flame, in fact, Fang Hao also had a lot of confusion, and he had been thinking about it during this time.

The spell flame looks like a flame, but it is actually a high-temperature aura, and the food baked is naturally different.

Bonfires are the same, Zuwu um bonfires are flames produced by a spirit stone, which is essentially different from mortal fire.

Fang Hao also found an interesting phenomenon, wet wood cannot be burned by mortal fire, it seems that it contains a fire-extinguishing element, and only completely dried dead wood can burn.

Even if the wet wood burns, it will soon be extinguished, and I don’t know what is going on, Fang Hao explained it as the rule of the world.

It is also simple to think about, if all fire can burn the wet wood of the flood, and the entire flood barren land is full of primeval forests, then fire alone can destroy the flood waste.

You know, there have been such super fires on the earth before, and this flood should be similar

。

Because large-scale fires use the high temperature of gas to ignite flammable materials, not flames.

The high-temperature gas of forest fires can form a moving firestorm, and the flammable material can burn when it touches the flammable, and the speed is amazing.

If the flood famine formed a super firestorm of mortal fire, I am afraid that the entire flood famine would burn.

Flood famine is different from earth, every rule of this world can be changed, and the heavenly way can set the rules of heaven and earth to where fire cannot spread, and flood famine naturally does not give birth to fire.

Perhaps in the distant creation era, all fire could also spread, but the Heavenly Dao modified this rule.

The above is just his boring conjecture.

The Terrans’ thinking ability is really strong, and there is no need for Fang Hao to remind them, and in the following days, the Terrans began to apply these flames, such as heating, roasting, lighting and so on.

The appearance of mortal fire signifies the birth of civilization, and without many people noticing, the era of civilization quietly slipped in.
