The Bronze Fortress shard sits on a large ring of rubble - there were dozens of separate kingdoms around the city due to the magic that used magic to expand the interior of the city! Therefore, when the ring city shattered, it created a ruin material that was ten million times larger than the foundation of the ring city. A part of the fallen multiverse has no recovery value at all; The other part remained in place and became part of this spectacular belt.

Even if this is a fantasy world of high magic, under the premise that the Lord of the World does not take the initiative to adjust the rules of the world, the basic physical laws still play a role. And the current world lord second generation is simply impossible to really adjust this law...... Because these laws of physics are the part he is most familiar with! If he arbitrarily alters a few cosmological constants and causes the world to become unrecognizable and completely incomprehensible with common sense, then he will die.

The reason why I mention this is because this circumferential debris belt, which has been spinning alone in a lonely world for a hundred years, is physically similar to an ordinary asteroid ring belt - which also means that those dust clouds floating in the ring belt can spread for thousands of kilometers at every turn, and all of them carry a huge amount of electric charge inside!

If such a dust cloud were to enter the spacecraft rashly, they would have a chain explosion like natural gas...... Or stick it up at a speed that can't be cleaned up and wrap the ship around a rock. However, when the fragments of the Bronze Fortress break into these dust clouds, they act like a large vacuum cleaner to suck the dust away.

Matter becomes the nutrients for the growth of fragments, so that the area of fragments around the city is quietly growing all the time; The charge carried by the dust cloud brings thunder and lightning to the world, which is then stored by the orichalcum foundation and turned into a free and clean energy source - electricity.

At present, the fragments of the Bronze Fortress are under the control of the Sunken Temple, like an oversized storage battery, which can store not only unscientific magic and divine power, but also scientific electrical energy, thermal energy, and so on. In fact, the other large fragments are similar, at most, the efficiency is not as high as that of the Bronze Fortress. But they don't have any means to make use of it, and electrical energy becomes a kind of "impurity" that is difficult to eliminate......

Penny's ability to control and process metal soon led to the creation of the world's first tungsten wire; It is also not difficult to find a vacuum environment, even if it is not created by sub-divine power, there is a vacuum everywhere outside the fragments of the ring city; The manufacture of special glass is the basic quality of an alchemist...... With the assistance of Shen Yan and Penny, the world's first light bulb was born behind the tungsten filament.

When an electric current is passed through a tungsten wire coiled in the shape of a double helix and heated above 3,000 degrees Celsius, a bright yellow glow appears and illuminates the room. Due to the unstable supply of electricity, the world's first electric light emitted the sound of electricity from time to time.

Michelle and the others looked at each other, not understanding what Shen Yan meant by inviting everyone to come just to see a "magic lamp". Augustine, in particular, as a legendary master of enchantment, felt that this was an insult to his craft - to say that a magic lamp, even if it was "electrical", he could make a lamp that bound a ball of thunder and lightning to illuminate, wouldn't it be ten thousand times better than this humble thing?

But in Shen Yan's eyes, the light of the electric lamp is ten thousand times more beautiful than the brilliance created by magic!

Michelle, Augustine, and others have all been to the world of the cartography room to get a glimpse of it, and in their eyes, thunder and lightning are just one of the forms of magic, no different from fireballs and acid rain. Only people like Shen Yan and Penny, who have lived in the drawing room for more than 20 years, can understand the relationship between electric energy and modern industry, and electric energy is the premise and foundation of everything!

When the lights came on, Shen Yan and Penny, who had transformed into shapes, jumped up excitedly and spun in circles around the venue with their arms on their shoulders! Dance the cheerful Xinjiang folk dance! (They'll only have this)

After the dance, the two men stood under the lamp and said to each other as if they were taking an oath.

"Shen Yan/Penny, welcome to the electric age!"

The people next to him were stunned, only Michelle peeked at Penny's face that was exactly the same as Shen Yan's, and her cheeks turned red.

*****

Even if some truths are explained 10,000 times, it is better to prove them once with examples, and the impact on preconceived ideas will be even more broken.

Facing Michelle's incomprehensible expression, Shen Yan's soul of an agricultural university graduate was burning! In the name of his diploma, he simply said, "Bet it!" Right in the agriculture you do best...... With electricity, I can double the grain production! To bet or not to bet? Winner takes all, loser kneel and lick! ”

"Impossible!" Michelle didn't even think about it, so she directly denied it. "My dear, standing in front of you is a legendary agricultural druid, and in the length of my life, the farmland I have taken care of may be more than the size of the Swan Continent, and I have never failed ...... What is the bet you want? Kneeling and licking something...... Didn't you do it a long time ago? ”

Michelle's voice grew smaller and quieter as she remembered her last failed bet. The most hateful thing about Shen Yan is that he ...... He doesn't bet with certainty.

The same in agriculture, the same bet on production – this time "30%". As a result, Michelle's "comprehensive breeding" + "magic deworming" + "wind and rain are smooth", and the yield is inferior to the "hybrid rice technique" of Yuan Dadruid, which Shen Yan said...... Let Michelle lose the last position of her body. The "end" after losing was extremely miserable, although the process was also very comfortable, but the result was that she could only sleep on her stomach for a while......

From then on, Yuan Da Druid was on her blacklist, vowing that if he saw ...... Please ask for advice.

"Are there any other Great Druids in the Cartography Room? You're not lying to me, are you? Michelle asked suspiciously, that place with a harsh environment didn't look like a world where great virtues could be born.

"Perhaps, Haber-Bosch, they ...... It should be considered an alchemist. Shen Yan said with emotion.

He remembered that the textbook said that although in 1838 Rouse made phosphate fertilizer, in 1850 Liebig made potassium fertilizer, and Rouse made nitrogen fertilizer. But another sixty years later, on the eve of the outbreak of the First World War, it was the German chemists Fritz Haber and Karl Bosch who really found the way to synthesize ammonia on an industrial scale.

Although we now talk about chemical fertilizers like a flood beast, it seems that everything is pure green and natural is the best. However, the problem is like the misuse of antibiotics – without antibiotics, billions of people on the planet would die from infections; Without chemical fertilizers, the earth's population would be directly reduced by 3 billion people, and it would be difficult for the population of China to exceed the limit of 1 billion.

The reality is that the synthetic fertilizer industry, which accounts for 2.5%~3.5% of the earth's industry, provides food for 45% of the world's population to survive.

However, out of political correctness, instead of blaming the exploding population that has overwhelmed the planet, people blame fertilizers for polluting the environment. Now they are starting to blame "genetically modified" again, and aside from the interests in between, the real problem that scientists who study genetically modified organisms want to solve is actually the serious question of "what will we do if the population increases to 10 billion by 2050". At present, the world's population is 7.444 billion, and China's is 1.41 billion, and according to the world's population growth trend, 10 billion is a figure that is likely to become a reality.

Of course, we are at an inflection point in population growth to breathe a sigh of relief and see India surpass us as the most populous country in the universe.

*****

The scales in Michelle's heart are moving up and down violently, on the one hand, there is unspeakable shyness, and on the other hand, there is unheard of forbidden knowledge!

What to do? What to do?!

There is now a good solution to Shen Yan's dissemination of the "forbidden knowledge" of the cartography room. If this kind of knowledge is transformed into a magic version, it can be taken out and used. The problem is that if you want to change your face, you need to do a lot of experimentation, and the experiment itself is equivalent to breaking the rules. But now with the closed world of the Ring Fragments, it is different, Michelle can be experimented and matured in this world and then taken out and used, which does not violate the rules of the cartography room.

Of course, there must be some limitations.

Shen Yan himself didn't want to spread this knowledge everywhere, thereby weakening his own advantages.

"If you lose...... What happens if you lose? ”

"I remember playing a game that was fun," Shen Yan rubbed his chin and smiled wickedly as he saw the elven wife at a loss. "How about becoming a cat lady this time?"

"What? It's so evil! …… Okay, well, if you lose...... But I'll win! The Great Druid blushed and said something he didn't have confidence in. She didn't know that it was precisely because of Michelle's shyness that someone always wanted to stop.
