The fragments of the bronze fortress are located on a large gravel ring belt. Because the ring circle used magic to greatly expand the internal space, there were dozens of independent kingdoms on the ring circle at that time! Therefore, when the ring circle was broken, ruins were made with a volume of tens of millions of times the size of the ring circle. Some fell into the multiverse and had no recycling value at all; the other part remained in its original place and became part of this spectacular ring circle.

Even if this is a fantasy world of high demons, the basic physical laws still play a role without the Lord of the World without actively adjusting the world rules. The current second generation of Lord of the World cannot really adjust this law... because these physical laws are the most familiar parts of him! If he randomly alters several cosmic constants and causes the world to become unrecognizable and cannot be understood with common sense, then he will die.

The reason for mentioning this is because this gravel belt around the city, which has been spinning alone for a hundred years in a lonely world, is similar in physical characteristics to that of ordinary asteroid rings. It also means that the dust clouds floating in the rings often spread thousands of kilometers in size, and carry a huge amount of charge inside!

If such dust clouds are rashly entered by spacecraft, they will explode like natural gas... or stick them on at a speed that cannot be cleaned and wrap the spacecraft into a rock. However, when the debris of bronze fortress breaks into these dust clouds, they will suck the dust away like a large vacuum cleaner.

The matter becomes nutrients for the volume of debris, allowing the area of ​​debris to grow quietly every moment; the charge carried by the dust clouds brings lightning to this world, and then is stored by the mountain copper foundation, turning it into free and clean energy.

At present, the fragments of the bronze fortress are like an oversized battery under the control of the sunken temple. They can store both unscientific magic and divine power, as well as scientific electricity, thermal energy, etc. In fact, other large fragments are similar, at most they are not as efficient as those of the bronze fortress. However, they do not have any means of utilization, and the electrical energy has become an "impurity" that is difficult to eliminate...

Penny's ability to control and process metals quickly made the world's first tungsten wire; it was not difficult to find a vacuum environment. Even without using sub-divine power, vacuums were everywhere outside the fragments of the city; special glass manufacturing is the basic quality of an alchemist... With the assistance of Shen Yan and Penny, the world's first light bulb was born like this after the tungsten wire.

When the current passes through the double helix tungsten wire and heats it to above 3,000 degrees Celsius, a bright yellow light appears and illuminates the entire room. Because the current supply is still unstable, the world's first electric light emits a "sizzling" current sound from time to time.

Mixueer and the others looked at each other, not understanding what Shen Yan wanted everyone to come just to see a "magic lamp". Especially Augustine, as a legendary enchantment master, he felt that this was an insult to his craft. Even if he was "using electricity", he could create a lamp that would bind a ball of lightning to light up. Wouldn't it be ten thousand times better than this simple 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 all went to the world of the drawing room to get a glimpse of it. In their eyes, lightning is just one of the forms of magic, and it is no different from fireball and acid rain. Only those like Shen Yan and Penny who have lived in the drawing room for more than 20 years can understand the relationship between electricity and modern industry. Electricity is the premise and basis of everything!

When the lights came on, Chen Yan and Penny, who had transformed into shape, jumped up excitedly, and rolled into circles in the venue with their arms! Dance the cheerful Xinjiang ethnic dance! (They only know this)

After the jump, the two stood under the lamp and said to each other like an oath.

"Chen Yan/Penni, welcome to the electrical age!"

The person next to him was stunned. Only Mixueer secretly looked at Panni's face that was exactly the same as Chen Yan, and her cheeks turned red.

*****

Some truths are explained ten thousand times, but they are not as good as examples to prove them once, which will cause even more impact on inherent concepts.

Faced with Mi Xueer's incomprehensible expression, Chen Yan's soul of the Agricultural University graduate was burning! In the name of his graduation certificate, he simply said, "Let's bet! Just in the agriculture you are best at... With electricity, I can double the grain production! Do you bet? The winner takes all, and the loser kneels and licks!"

"Impossible!" Mixue'er directly denied it without thinking. "Dear, the one standing in front of you is a legendary agricultural druid. In terms of my life, the farmland I have taken care of may exceed the area of ​​the Swan Continent. I have never let it down... What is the bet you want? Kneeling or something... Haven't you done it long ago?"

Mixue'er's voice became smaller and smaller because she remembered the experience of failing to make a bet last time. The most hateful thing about Chen Yan is that he doesn't make a bet without confidence.

In terms of agriculture, the same bet on the output was to increase the output by 30%. As a result, Michelle's "full breeding" + "divine deworming" + "good weather", the yield was inferior to the "hybrid rice technique" of Yuan Darui mentioned by Chen Yan... and made Michelle lose her last position in her body. The "end" after losing was extremely miserable. Although the process was also very comfortable, the result was that she could only sleep on her tummy for a while...

From then on, Yuan Dadrui was on her blacklist and swore that if he saw it... he would definitely ask for advice.

"There are other big druids in the mapping room? Are you lying to me, aren't you?" Mixueer asked suspiciously. No matter how bad the environment looks, it doesn't seem like a world where great masters can be born.

"Maybe, Haber Bosch, they... should be considered alchemists." Chen Yan said with emotion.

He remembered what the textbook said, although Rolls made phosphorus fertilizer in 1838, Libich made potassium fertilizer in 1850, and Rolls made nitrogen fertilizer. But sixty years passed, and it was not until the eve of the outbreak of World War I that German chemists Fritz Haber and Karl Bosch truly found a way to synthesize ammonia on a large scale on industrial scale.

Although we now talk about fertilizers, it seems that everything is pure green and natural. However, this problem is like the abuse of antibiotics. If there are no antibiotics, there will probably be billions of people on the earth who die from infection; if there are no fertilizers, the population on the earth will directly decrease by 3 billion, and it will be difficult for the population of China to break through the limit of one billion.

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

However, out of political correctness, people do not blame the explosive growth of the population that makes the earth unbearable, but accused fertilizers of polluting the environment. Now they are beginning to accuse "GMOs". Excluding the interest relationship between them, the real problem that scientists studying GMOs really want to solve is actually the serious problem of "what should we do if the population increases to 10 billion by 2050." Now the world's population is 7.444 billion and China is 1.41 billion. According to the world's population growth trend, 10 billion is a very likely number to become a reality.

Of course, the turning point of our population growth is coming, so we can breathe a little relieved and watch India surpass us to become the largest population country in the universe.

*****

The scale in Mixue'er's heart was moving up and down violently. On the one hand, it was shy and unheard of taboo knowledge!

What to do? What to do?!

There is now a good solution to the "tag knowledge" of the Shenyan Dissemination Mapping Room. If this kind of knowledge has been changed into a magic version, it can be used. The problem is that if it is not that simple to change it, it requires a lot of experiments, and the experiment itself is equivalent to breaking the rules. But now with the closed world of the city fragments, it is different. Michelle can be used in this world before using it after being experimented with in the world, which does not violate the rules of the Mapping Room.

Of course, there must be some restrictions.

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

"What happens if you lose...what will happen?"

"I remember playing a game that was very interesting," Chen Yan rubbed his chin, watching the elf wife being at a loss and smiling evilly. "How about becoming a cat girl this time?"

"What? It's so evil!...Okay, okay, if you lose...but I will win!" The big druid blushed and said something she had no confidence. She didn't know that it was because of Mixue's shyness that someone always couldn't stop.
