Beneath Deep Space

As the slides were played one by one, Yu Yifeng was also shocked.

Such underground magma canals would have been unimaginable in primitive times! How much work does this require? How many lives do you need to fill it?

You must know that this is underground, which is more difficult than digging a "Beijing-Hangzhou Grand Canal"!

Moreover, things like magma will slowly solidify and cool into stone, so after the canal is completed, it will need frequent cleaning and maintenance to operate normally, which increases the amount of work...

This large magma river is the carnival of the ruling class and the cry of the slaves... but at the same time, it does feed a larger population and is a great initiative. Nix people rarely need food. Their digestive function is not good. They only absorb necessary nutrients through food. The main energy source is geothermal energy.

Only slaves will consume large amounts of food to obtain energy, but their lifespan is often short...

Other tribes saw the benefits and began to follow suit. But digging canals required a huge amount of labor, so they launched wars one after another to seize more slave resources...

The endless scenery belongs to the sage class and the ruling class...

But from a historical perspective, slaves were the class that sacrificed the most. They used the simplest tools to create epic greatness. The blood and tears they shed are not enough to fill a hundred magma rivers!

The ruins of a large lava river lie beneath the city of Thor.

It's a pity that as time goes by, it has been filled in by solidified magma and stones... people can no longer see what it looks like.

The entire slave era lasted for a long time, and the deadly work of maintaining the canal could only be done by slaves.

Dynasties changed, slaves revolted, and waves of bloodshed swept across the country...but the system of slavery never changed.

The lava river must exist, so... slaves must also exist.

"The social development here is different from that of us humans. Their feudal system and slavery have always coexisted. No matter how strong the opposition is, slaves will always exist..."

However, the pace of science will not stop because of bloodshed, killing, exploitation and being exploited...

The sage class of Nix civilization, that is, the scientist class, has always been detached from the world.

From ancient times to the present, Nix civilization’s pursuit of wisdom has never stopped. Dynasty changes have little to do with the sage class.

Several powerful tribes unified to form a country, and wars often broke out between countries, but all rulers were respectful to engineers and scientists.

Without engineers, the country will soon weaken; without scientists, technology will soon be surpassed by other countries...

Knicks scientists are still making a fuss about magma, hoping to make magma play more roles besides heat.

In this way, time passes year by year.

War is the best catalyst for science, and the pressure of survival is also an accelerant for the growth of science.

The living environment here is too poor. Volcanic eruptions or earthquakes can easily kill a large number of lives. The protection of a magma river is far from enough. The Knicks urgently need more powerful industry to fight against nature!

As time passes, one hundred years after another, mathematics, engineering, and mechanics have been invented one after another... which has indeed brought more powerful power, making the Nix civilization's worship of wisdom even greater.

Finally... "Kang", the 22nd great sage in history, established the modern chemical system!

Modern chemistry was born!

The birth of chemistry was an unprecedented breakthrough, which meant that they had a better understanding of various substances in the world.

For the first time, they learned about the existence of oxygen and began to try to create real combustion.

"The first organic combustion phenomenon on the planet Nix was born in the hands of the Great Sage Kang! That is, the burning of wood fibers in pure oxygen."

Hearing this, Yu Yifeng was really sad.

Only after the Knicks invented modern chemistry and understood the nature of combustion, could they create a small amount of oxygen and then use the combustion phenomenon that humans are accustomed to...

In comparison, humans are so happy...

How kind Mother Earth is to mankind!

But then again, even if chemistry appeared, the social era they lived in was still the slave era. Many jobs were still extremely dangerous and required slaves.

Chemistry doesn't change their situation much.

Because the oxygen content in the atmosphere is very low, it is not easy to produce oxygen through chemical means. Even if we use industry to extract oxygen from the atmosphere, it is extremely complicated and expensive because of the low oxygen content.

Especially...oxygen is poisonous to them!

Chemistry, so far, has not been of much use... At most, it has improved the lives of the wealthy class, but has not fundamentally changed the entire society.

But the emergence of chemistry was indeed useful and promoted a large number of subsequent scientific developments.

until……

Three hundred years later, the twenty-fifth great sage "Dyrane" discovered the phenomenon of electromagnetic induction.

An all-round breakthrough has begun.

A historian of the Nyx civilization excitedly recorded in a historical work: "It was an ordinary day, but also an unusual day. A huge sound came from the lava river, and then everyone in the city heard To the point of shouting like crazy..."

"Geothermal energy generator appears in this world!"

This scientific giant actually invented a geothermal energy generator based on the phenomenon of electromagnetic induction! This has produced truly huge changes in society as a whole!

"...Electricity is a huge, bright light that suddenly appears in the underground world. It only takes three years to grow from a baby to a giant, but it directly grabs the throat of darkness! This is the first time the world looks like this bright."

"This invention of Duke Dilarn has legitimately earned him the title of Great Sage. Even the rulers of enemy countries cannot refute..."

"Even... among the 25 great sages that have ever appeared, it is also the well-deserved number one!"

"Electricity is also called the light of wisdom!"

The age of electricity has arrived suddenly!

"It's like a whirlwind, roaring across the entire underground world! The darkness fades away, and the Nix civilization is reborn, ushering in a new era!"

"A great era!"

When hearing this paragraph, all the humans present were excited.

At this moment, they seemed to have transformed into Knicks, witnessing with their own eyes the entire process of a civilization from weakness to rise.

Although the sad ending of this civilization has been doomed, at this moment of its rise, people are still excited for it.

This is the eagle spreading its wings and emerging from its cocoon to become a butterfly!

This is a kind of touching feeling, a kind of wonderful beauty brought about by the progress of civilization.

Species are different, but emotions are the same. Every species has the right to pursue a better life.

From them, people seem to see the shadow of their own rise. From the Renaissance, to the Enlightenment, to the birth of modern science, every bit of human progress has been hard-won. The people here are moved by their own progress and by the dedication and efforts of the pioneers.

The history of Knicks civilization is heavier and more depressing.

It’s not that human beings have never experienced such a cruel stage, but the Knicks are experiencing cruelty at every historical moment.

The emergence of electricity is really as warm as the newborn sun.

They finally saw something called "hope" being born!

They can finally escape the dilemma of energy poverty.

They can finally stand up in a world without fire!

A machine called "Geothermal Steam Generator" began to spread widely, and the ruler who prevented its spread... was directly guillotined by the rebels!

This is an unrivaled trend!

In essence, magma is still magma, and not much has changed. But now it has an additional function...generating electricity!

"Geothermal steam generator", just like human thermal power stations, can convert thermal energy into electrical energy through steam. This is just one more small step, but a huge leap in production capacity has been achieved.

Magma can indeed provide huge amounts of thermal energy, but thermal energy is an energy source that is not very easy to utilize for industry.

Moreover, magma dissipates heat all the time, causing a lot of waste.

If we use it to generate electricity and build a large power station, the energy that can be used will increase more than a hundred times?

The electric age of the Nyx civilization developed extremely rapidly. Electric energy began to quickly replace the original magma heat energy and become a stronger energy source.

Thanks to the book friend "Boring 2B Youth" for the tip, thank you!
