The big man has a living father

Chapter 252 (Long Chapter) Dispelling the Long Night
On the second floor of the side building of the stock trading center, Liu Che, as usual, was overlooking the situation below.

The difference is that this time, Liu Ju is also here.

After Liu Che realized that Huo Hai intended to push Princess Wei to the throne, he gave Liu Ju more advice.

In fact, Liu Che's act of advising Liu Ju was to approve Huo Hai's act of letting Princess Wei Chang challenge the imperial power.

If Liu Che wanted to stop it, he would have stopped it long ago. The reason why he helped Liu Ju was that he felt Liu Ju could not win, so he had to do it himself and let Liu Ju fight against Liu Lian.

While watching, Sang Hongyang told Liu Che and Liu Ju about the invention of the internal combustion engine.

After hearing this, Liu Che looked back in surprise, very surprised.

Liu Ju widened his eyes and expressed disdain.

Liu Che: “Really?”

Sang Hongyang: "It can indeed work, absolutely, but according to the Minister of Agriculture, this structure has shortcomings, and another four-stroke structure needs to be developed before it can be used."

Liu Che: “Four strokes?”

After listening to Sang Hongyang's description, Liu Ju already knew what was going on.

He started drawing on the blackboard next to him: "It's probably like this."

During the intake stroke, when the rotor inside the lower cavity runs to the far end, the space in the upper internal combustion chamber becomes larger, and the intake valve opens, so air and vaporized fuel gas (diesel, gasoline) are naturally inhaled.

During the compression stroke, the rotor continues to rotate due to inertia. When it has rotated half a circle, the gasified diesel and gasoline mixed with air are compressed into a very small area, and ignited at this time.

In a very small space, the gasified diesel gasoline mixed with air exploded.

During the power stroke, the explosion drives the rotor to rotate, and the transmission mechanism connected to the rotor provides power to the outside of the internal combustion engine, which is the same power as a steam engine.

After this explosion, the rotor still has very strong kinetic energy and continues to rotate due to inertia.

During the first half of a revolution, the combustion chamber is compressed, the intake valve is closed, and the exhaust valve is opened to discharge the burned exhaust gas out of the internal combustion chamber.

At this time, the entire combustion process is completed.

Next, under inertia, the rotor continues to rotate, inhaling air in the fifth and a half revolutions, inhaling oil and gas in the sixth and a half revolutions, exploding with a bang in the seventh and a half revolutions, and exhaust gas in the eighth revolutions.

This cycle repeats a second time, and the reciprocating engine continues to work on the piston up and down.

Liu Che didn't understand just by listening, but he understood after Liu Ju gave a lecture.

After understanding, Liu Che said: "That's great!"

Of course Liu Che thought it was great.

Ever since the emergence of chemical industry from fossil fuels, Liu Che has fully understood the benefits of oil and coal.

Not to mention anything else, kerosene alone gave the Han army an overwhelming supply capability against the armies of other countries.

Emperor Liu Che attached great importance to the chemical industry of petroleum.

Petroleum products such as gasoline, kerosene, diesel, lubricating oil, paraffin, asphalt, petroleum coke, liquefied gas, etc. are all extracted from petroleum.

At present, heavy fuel oil is about to be used as the energy source for the new northern railway.

Liquefied gas has been used on a large scale, with paraffin and asphalt being the most used. They have been used continuously in house construction in recent years. Previously, in Shenmu, the surface oil that was mined was only gasoline and diesel after all the substances were extracted.

What gave Liu Che a headache was that this oil was useless!
The most common company is General Motors, which makes heating systems and manufactures some structures for gasifying diesel for small-scale industrial production.

However, this structure needs to be preheated before it can be used, which is very troublesome and difficult to maintain.

The point is, they are expensive to make and have relatively little effect.

You know, coal is very cheap, so who would install a gasification diesel steam engine for production?

Therefore, diesel and gasoline in the petroleum are waste to the current Han people, and they are also highly polluting. They know that they are somewhat useful but do not know where they can be used specifically. They can only spend money to produce and seal the waste in cans.

Now, this problem has finally been solved.

Liu Che knew very well that the transportation industry was the foundation of everything in the Han Dynasty.

If the internal combustion engine can be used in a horse-drawn carriage, that means... the horse is retired!

From now on, every car can be powered by an internal combustion engine!

The gas engines of the past were so complicated that steam cars needed to be preheated for a long time before they could start, and once the steam was released, it would be the end of them.

The structure of an internal combustion engine is obviously different. The operation mode of an internal combustion engine is that the gas mixed with air explodes and pushes the piston.

With such a structure, there is absolutely no preheating. Even if there is, it will only take a few seconds at most.

That is, when there is no combustion power to push the piston, human power can turn the piston for a while and it will ignite.

Such a thing can be started and used at any time.

This convenience will surely become popular.

Although there are certainly many problems that cannot be solved technically at present.

However, as long as we have a direction, we will surely progress to this day in the future, and it won’t take too long!

Liu Che understood that this day would come soon, when oil would be used for everything from start to finish, and there would be nothing left!
This is such a great treasure!

In contrast to Liu Che's excitement was Liu Ju's disdain.

Liu Ju believed that the internal combustion engine had a huge problem, which was that oil was difficult to extract.

Liu Ju has learned that there are very few places where oil is produced, and oil is generally found deep underground. Within the scope of Lao Dahan, there are only two places with surface oil, Shenmu and Longxi.

What can this little bit of oil do?
In other words, using oil requires a huge cost, digging it out from other places and then transporting it to places like Chang'an that consume gasoline.

But electricity is different.

There is coal everywhere in Han Dynasty, and the coal being discovered now is simply inexhaustible.

This coal can be used to build thermal power plants everywhere.

The thermal power plant builds the lines on the entire land of Dahan, and the trams can run as long as they are powered by electricity.

Why should we develop internal combustion engine cars? Electric cars are the future!

Liu Ju: "Internal combustion engine vehicles have no future. Electric vehicles are the future."

Liu Che turned around and looked at Liu Ju: "?"

Liu Ju: "It takes too much manpower to extract and transport oil, but it is much easier to extract coal. As long as there is a power plant, there will be electricity in the city at any time, and the trams can be operated."

Liu Che looked at Liu Ju and said nothing.

With Liu Che's smart brain, the first thing that came to his mind was a question.

If a rebel army runs to a high ground or an open field where there are no electric wires and occupies it, how can you use trams to transport strategic materials?

For example, if the enemy occupies Bashang, you first use trams to transport cannons to the downstream of Bashui, and then use manpower to carry them up?

But internal combustion engine cars are different.

There are no restrictions, you can run as long as there is a road.

Drag the cannon directly in front of the enemy and launch a round of bombardment.

Starting from Chang'an, any rebellion within a hundred kilometers of Chang'an can be dealt with in three hours.

For this reason alone, internal combustion engine cars are much better than trams.

The biggest feature of automobile transportation is convenience.

Assume that tram line AB is a fixed line.

A businessman has his warehouse one kilometer away from point A and his shop one kilometer away from point B.

If it was a tram, he would need to find people to carry the goods from the warehouse to point A by human or horse. Then, after arriving at point B, he would ask another group of workers to carry the goods from point B to the store by human or horse.

How complicated is this process?

If it is an internal combustion engine car, just load the goods from the warehouse and unload them from the store.

What is the difference here?
The difference is that after the road is repaired, it can be used for everything. People can walk on it, cars can drive on it, and everything can drive on it.

The circuit function is single.

Circuits are too expensive, so it is impossible to build circuits everywhere where roads are built.

Also, what if cars coming in opposite directions collide head-on?
When using circuits, are they divided into public and private?

Do the imperial court cars have priority in using electricity? Do ordinary people's trams have the second-class right to use electricity?
These troubles meant that trams could never compete with internal combustion engines.

Not even as good as an internal combustion engine.

However, Liu Che did not say it.

Liu Che just looked at Liu Ju.

Liu Ju did not have the thinking that a person in power should have. He did not look at the problem from the perspective of humanity, nor from the economic perspective, but instead looked at the problem from a technical perspective first.

Technically, electric motors seem to be better than internal combustion engines, and mining coal is easier than mining oil.

However, until electricity can be stored in the car, allowing the car to go anywhere autonomously, internal combustion engine cars are definitely better than electric cars.

If Liu Ju became emperor and encountered such a huge crossroads in the future, would the probability of him taking the wrong path be too high?

Liu Che was thinking about this problem.

In fact, Liu Che was really overthinking.

When it comes to science, there is no real right or wrong.

For decision makers, making the wrong choice is the norm. How can anyone make the right decision every time? It is even impossible to make more than half of the decisions right.

Because! Any decision will be problematic in hindsight. There are always various things that were not done well.

When people make any decision, 90% of the time they will think afterwards, "I wish I had made a different choice."

The fact is, even if you chose the other option at the time, you would still end up thinking, "I wish I had chosen differently."

Therefore, there is no optimal solution at all.

It’s just that Liu Che himself has a much smarter mind than others, and can calmly analyze the final profit of each option and which one has a clear advantage.

Others can only vaguely sense the difference, but Liu Che can quantify the difference. So Liu Che can prioritize things that others see vaguely.

This is what makes Liu Che so powerful.

But if Liu Che wanted his successor to have such ability, he would be dreaming.

The problem is that the entire court is a gathering of all the smart people in the world.

Especially the three brothers of the Huo family, who gave Liu Che an illusion, the shocking illusion that "it is easy to have a smart child."

Liu Ju was a very smart man after all, at the forefront of technology, and he had no idea that his father was doubting his intelligence.

At this time, Liu Ju was still excitedly talking about the advantages of trams.

"The quietness of electric motors is something that steam engines and internal combustion engines can never match."

"The complex mechanical structure of the internal combustion engine means that the start-up phase will be very slow, while the electric motor will be very fast."

"Father, can you imagine that today's trains only rumble but do not run. They move slowly forward half a mile before increasing their speed a little, and then slowly increase their speed after running four or five kilometers. And in the future, in just a few hundred meters, they will be one, two, even four or eight times the speed of today's trains!"

Liu Che nodded: It's not completely without merit. It is possible to build electric trains on railways, but it is absolutely impossible to build electric trains on roads.

Because most of the time, the trains on the railway run on their own, but it is not the same for people on the road.

According to Liu Che's statistics, among those who took to the road, 70% were normal, and 30% had mental problems. There were strict regulations, but they did not abide by them.

Even if they are caught, they will not regret being caught for breaking the rules, but will only regret not hiding better when they were inspected.

With these things, if all the cars on the road were trams, then the traffic would be jammed every day.

Even if trolleybuses are invented in the future, it will be useless.

Unless energy storage trams are invented.

Unfortunately, Liu Ju didn't seem to have thought of this.

Liu Che thought for a moment and said, "Wait for your brother-in-law to come up and see what he says."

After hearing what Liu Che said, Liu Ju was also very curious about what Huo Hai would say.

After a while, before it got dark, Huo Hai came here and met up with Liu Che.

Huo Hai was a little surprised when he saw the four-stroke diagram on the blackboard.

I remembered this thing wrong at first. It was only after seeing the actual picture of the two-stroke that I recalled the four-stroke structure diagram.

Although this thing later became a compulsory subject in the nine-year compulsory education, it was not a required subject when Huo Hai was in school, and Huo Hai also learned it by watching videos.

What I watched was a video on the refurbishment and repair of an internal combustion engine.

Liu Che: "What do you think of internal combustion engine cars and electric cars?"

Huo Hai immediately realized that it was Liu Ju's fault and turned around and asked, "Prince, what do you think?"

Liu Ju: "The cost of electric vehicles is much lower than that of internal combustion locomotives."

Huo Hai and Liu Che shook their heads at the same time.

Liu Ju was stunned for a moment and asked, "Brother-in-law, don't you think so?"

Huo Hai: "If Changan is the only car manufacturer in the Han Dynasty, and the number of cars is less than 5,000, they will run on fixed routes and serve as public transportation vehicles, just like intercity railways, and form a transportation network in Changan, then the cost of electric cars will be much lower than that of internal combustion engine cars."

"But if all the hundreds of cities in the Han Dynasty use cars, and even between cities, cars are everywhere, then internal combustion engine cars are definitely cheaper."

Liu Ju: "But electric motors have huge advantages over internal combustion engines, and electric vehicles should also have huge advantages over internal combustion locomotives."

Huo Hai shook his head: "These are two different things."

“Electric motors have advantages, but that doesn’t mean electric vehicles have advantages over diesel locomotives.”

"It's like, heavily salted ham is much more expensive than lightly salted cured pork trotters, but if they are stewed with salty kelp, the cured pork trotters will definitely be more fragrant than the ham."

"It's like when you eat porridge, pickles are more reliable than braised pork."

“The best is the right one, not the best when put together.”

Liu Ju: "Good is good."

Huo Hai was helpless: "In a hundred years, the internal combustion engine will lift up the tram and hit it. I can't say what will happen in a hundred years. At least I won't be able to see it."

I could have seen it in my previous life, but suddenly I traveled through time and space and no longer have the chance to see it.

Liu Che added: "If your brother-in-law can't see it, then you can't see it either. You are no younger than your brother-in-law by two years."

Liu Ju was a little angry because he felt that he was an expert in this field and his authority should be higher than Huo Hai's.

Seeing that Liu Ju was not convinced, Huo Hai asked, "Let me ask you a few questions."

"The first question is, if the horsepower of the tram increases and the speed increases, how can we protect the safety of the passengers inside?"

Liu Ju: "Replace the wooden carriages with iron carriages."

Huo Hai: "Okay, the first question is, if there is a power leak in the tram or the railway carriage, how can we protect the safety of the passengers inside?"

Liu Ju: “…”

Huo Hai: "The second question is, if the motor speed increases and the iron wheels of the tram slip, what should we do?"

Liu Ju: "Sandblasting, don't think I can't think of this method, I came up with it independently of the railway design of the institute."

Huo Hai: "Okay, the railway is sandblasted, but the city roads are full of sand. Should we sweep them? If there is too much traffic and there is no time to sweep during the day, and the pits are full of sand, what should we do if they derail?"

Liu Ju: “…”

Huo Hai: "The third question is, if there is a power outage in the whole city, and the streets are blocked by cars, what should we do if the power repair team cannot transport equipment to the damaged line?"

"The fourth question is, what if a tram short-circuits and the nearby lines become unusable, resulting in a large number of trams breaking down?"

It is impossible to use trams on a large scale.

Huo Hai continued: "The fifth question is, what if the car is going uphill and the motor loses power and cannot suppress reverse rotation, causing the car to slide backwards?"

This problem has not been solved even for the cars in 2024, let alone now.

Liu Ju was overwhelmed by what he heard. Huo Hai had another question: "If a grand event is held somewhere in the city, just like the Han Expo today, then all the trams in the city will run in the same direction, causing the voltage in this half of the city to be unstable, and the power consumption pressure will exceed the normal load by several times. As a result, no one can use electricity and all the trains will break down. What should we do?"

This is no longer a technical issue, it is a human issue.

The end is almost here. Who will quit and who will continue to enjoy the electricity?

In this situation, those who are willing to quit will always quit, and those who hold on will always hold on.

In the end, wouldn't it be that only people with thick skins can drive in the city, while people with thin skins can't even move a step?
Liu Ju: "I still think trams are better."

Huo Hai: "Are you planning to start a car factory called Mercedes-Benz?"

Liu Ju nodded.

Huo Hai: "Take my advice, this brand is destined to be suitable for gasoline vehicles."

Liu Ju was speechless: "Brother-in-law, how can you still count your life."

Huo Hai shrugged.

Huo Hai came up and tried to persuade him, and Liu Che saw the whole process.

Huo Hai told Liu Ju almost all the problems with the tram without keeping anything secret.

In fact, the problems that Huo Hai saw were more than twice as many as those that Liu Che saw.

This made Liu Che feel a lot more comfortable. Although Huo Hai wanted to help his wife fight for the throne, he had no intention of giving up the crown prince.

You should know that Huo Hai had served as the Prince's attendant and the Prince's Secretary's Office!
The prince used to be taught a lesson every few days.

Now, Huo Hai still does not hide anything.

What gave Liu Che a headache was that Liu Ju was so stubborn.

Liu Che could not help but speak up: "Sometimes, the best is not necessarily really good, it may also be a huge trap. For the royal family and even the emperor, most decisions must consider more than one factor, and must first consider the overall situation."

"Sometimes, the situation forces you to choose a completely wrong answer."

Liu Ju: "There is only one truth."

Liu Che looked at Liu Ju, very curious. What would Liu Ju think if one day he found out that the three laws of mechanics were actually invented by his master Dong?
Thinking of this, Liu Che remembered that Dong Zhongshu had gone to study new theories and seemed to be a little crazy.

He originally looked very good, much better than Sima Xiangru, who had a son in his old age. But recently he looks a little confused.

Liu Che shook his head: "I heard that Dong Yan is back?"

Huo Hai nodded: "Dong Yan came back to report on his work. He returned to Chang'an before the general attack and is now serving as the lieutenant of Xi'an Gate in Chang'an."

This Xi'an is not the Xi'an of later generations.

The south gate of Chang'an City was called Anmen, and the gate to the southwest was lazily named Xi'anmen.

After Dong Yan came back, he served as a captain there.

That place was the entrance that Liu Che least often went through.

Huo Hai patted his thigh and said, "By the way, Dong Yan opened a field supplies store in Chang'an, selling various tools popular on the grasslands, tents and the like."

"He may want to make this into a luxury product. He has found some explorers to endorse his products and sponsored an exploration team to explore South America. Oh, and there is also an exploration team to the South China Sea. However, the exploration team in the South China Sea went out in a small boat, so it is estimated that it will be difficult to achieve results."

Liu Che put his hands on his hips and said, "You promised him that if he separated from Dou Taizhu, you would not embarrass him, right?"

Huo Hai nodded: "Do as you say."

Liu Che: "Did you see that Empress Dou has not been in good health recently and you were afraid that she would go north and take Dong Yan away, so you deliberately let Dong Yan come back?"

Huo Hai was stunned for a moment and shook his head: "That's not what I meant. Dong Yan chose them himself."

Liu Che nodded and said, "Dong Yan is my friend after all, you can do whatever you want."

Looking at the sky outside, Huo Hai interrupted: "Your Majesty, it seems that it is almost time."

Liu Che nodded: "Let's go downstairs."

Downstairs, a large number of viewers actually couldn't wait any longer.

They've all heard that the highlight is after dark.

But it was really dark at this time and everyone was unhappy again.

There is not even a kerosene lamp or a lit lantern.

I thought there would be a lantern festival, but there was nothing.

What are you doing!

A night banquet? Eating in the dark?

However, there were still some people with sharp eyes who saw Liu Che with the little light.

"His Majesty!"

"Your Majesty is here, the main event is about to begin!"

The scene suddenly became noisy.

However, after most people turned around and faced the platform where Liu Che was, the noise became louder and louder.

"What exactly is the highlight?"

"Oh my god, I saw so many high-tech products today. What can be the protagonist today?"

"Who said it wasn't true? I've learned a lot today."

"What are you doing? Why haven't you announced it yet?"

Liu Che and Huo Hai were standing on the platform at this time.

Liu Che: "How far can the lighthouse shine with high-power electric lights?"

Huo Hai: "How much power?"

Liu Che clicked on the light switch.

At this moment, a ray of light lit up on the platform.

The noise at the scene disappeared without a trace in a second.

Everyone fell silent.

Because it is dark, the bright areas are more obvious.

Because it was dark, everyone could see the lights clearly.

It was a steady light without any wavering.

There is no ignition process, it is not an oil lamp, the light is downwards, not upwards like an oil lamp.

What it is?
Why can that thing glow?
Liu Che turned on the first light facing the public.

Huo Hai also pulled down a switch.

The colorful lanterns hanging everywhere were lit up one by one.

Colored glass, which has become popular in recent years, is used to make electric lamps.

However, more electric lights were placed all over the square, including above the crowd.

Everyone saw that the surroundings suddenly became brighter, and they suddenly looked up at the charming lights.

"This is……"

"What!"

Someone in the crowd looked at Huo Hai.

Huo Hai once wrote a poem to describe Confucius. Huo Hai said that he admired Confucius the most and called Confucius a saint. He also wrote a line for Confucius: "If Confucius had not been born, the world would have been dark forever."

Unfortunately, even Confucius could not dispel the long night.

But Huo Hai can.

This is the first truly stable light that has been lit in countless nights since the birth of mankind.

The sky and earth have been dark countless times, but this is the first time the darkness has been dispelled.

Liu Che raised the megaphone and said, "Hello, can you hear me?"

Sound: "Zi~ya~zi~zi~!"

Liu Che was helpless: "The current electric speakers are not good enough, they can barely be used, you just listen to them."

The scene was in an uproar.

"What's this?!"

"What's that light? What's that sound?!"

"Fool, this is the light of wisdom and the echo of technology!"

Liu Che: "What you see is called electric light, which uses electricity. Simply put, the steam engine burns under the boiler and uses the power above the boiler. Electricity is burning coal a few streets or dozens of streets away, and uses the power here a few streets away."

Such a simple description allows everyone to immediately have a clear understanding of electricity.

Liu Che, with one hand on his waist, said: "The first expo of the Han Dynasty must have a heavyweight exhibit to be of sufficient significance."

"Welcome to...the Electric Age!"

The steam age has only been here for less than a decade, but it has already brought about radical changes in everyone's life.

Ten years ago, almost every ordinary person could not get enough food to eat. Although grain production was sufficient, the grain had to be used for many things.

At that time, ordinary people basically relied on shivering to keep warm in winter.

The price of a bundle of firewood in Chang'an City could cost half of your life.

Ten years later, wearing thick cotton clothes, even at night, few people standing here are hungry. Who doesn't have enough food these days? People usually eat a lot, so going hungry is not as life-threatening as it used to be.

They can eat well, dress warmly, study, make money, and even eat fruits sent from thousands of kilometers away, which were things that even the emperor could not afford before.

You can eat seafood from the East China Sea, grapes from the Western Regions, sheep from the northern grasslands, and drink tea from Chengdu in the south.

Who doesn't have two pairs of dog-skin and pig-skin shoes these days? If not, then this guy must be wearing lambskin, which is too luxurious.

Nowadays, some people break their teeth from chewing bones, and they all secretly replace them with big gold teeth.

This terrifying steam age is a good time that was unimaginable ten years ago.

However, today, His Majesty the Emperor himself announced that the steam age is a thing of the past, and welcome to the electrical age!
Everyone was shocked.

After Liu Che finished speaking, he threw the loudspeaker to Huo Hai.

The speaker of this thing was too close to him, and Liu Che couldn't listen to it anymore.

This speaker is more explosive than the loudest microphone Huo Hai has ever heard in his life.

Huo Hai didn't want to say more, so he picked up the speaker and said, "Electricity has many wonderful uses, and today is just the beginning!"

"But at the beginning, we must let everyone know the disadvantages of good things. Electricity is good, but such a huge amount of energy is not something that mortals can handle."

"Electricity needs insulating materials, such as rubber, to insulate it. On the wires, it is rubber and rubber mixtures."

"And if it's not isolated, the effect is..."

On the stage, a pig was led over.

Under the spotlight of the crowd, this pig became straight for the first time in his life.

There's smoke coming out!
"I am Cao!"

"What the hell, it's gone just by touching it?!"

"I know now. The guy who stole the copper wire was electrocuted to death!"

"Hey, who wants to steal this? I don't want it anyway!"

Huo Hai: "Don't even mention it's a pig, even if it's a cow~"

A cow was electrocuted and jumped around.

"This cow is so miserable. That pig just fell asleep. But this cow can hold on. The more it holds on, the more miserable it is."

"I smell barbecue. So this is what roast beef smells like."

“It’s all burnt!”

Huo Hai continued: "The pigs, cows and sheep used in the experiment are to tell everyone the power of electricity. If you are not a professional, you must use electricity under guidance and do not directly touch exposed wires!"

"Okay, get another sheep, collect enough for the old man, and send it over, so that the old man will also know that our people have access to electricity."

Huo Hai made jokes and made the frightened people laugh.

Looking at professionals like Huo Hai, who are not afraid of electricity, everyone will understand that if you don’t understand it, there will be great harm. If you understand it, there will be no big problem.

Huo Hai didn't waste any more words: "Starting tomorrow, the entire Chang'an will begin to gradually lay out the power system and build thermal power plants and hydropower plants."

"Because of the special nature of electricity, I personally ordered that power facilities and scientific knowledge in this area be blocked from leaking out. Tomorrow, Science News will publish a special issue on electromagnetics to let everyone know about the developments in recent years."

"Well... before you see the newspaper, let's invite the discoverer of electromagnetic theory, Fateh, to explain it to everyone!"

When Huo Hai was speaking, the speaker was a little better and not so harsh, so he said a few more words.

But after talking too much, I still see stars.

In the end, the horn was thrown to Fati.

The young man back then is now middle-aged.

Fati actually wanted to invite Dong Zhongshu to go on stage with him.

It’s a pity that Dong Zhongshu didn’t come.

Fati took the microphone and said: "First of all, the electromagnetic theory was not discovered by me alone. I would like to thank my long-term research partner and friend, Mr. Niu Dong."

"Oh, the word sir means someone who was born before me and has more power than me. It is a respectful word that I asked the Minister of Agriculture to tailor for me after I consulted him."

"Mr. Niu did not want to be exposed to the public for some reason, so every time such a meeting is held within the institute, I am the only one who enjoys this honor."

"And today..."

Fati said a lot.

Although it was harsh, the audience listened to the whole thing forcefully as it was their first time hearing this magical sound amplifier.

The more I listen, the more magical it seems.

Even the problem of hearing loss that had lasted for years was cured.

The lights are bright and the music is magical.

This is how many people remember this dreamy night.

In fact, in Huo Hai's opinion, the lights that night were dim and barely usable, and the noise was unbearable.

But Huo Hai knew better than anyone that this was a good start.

It took Huo Hai ten years from coming into this world to the first day when the electricity era was announced.

It has been nine years since I came to Chang'an.

For the tenth year, Huo Hai sat in the office of the Minister of Agriculture and watched as the houses in Chang'an were lit up one by one.

The streets of Chang'an are lit up one by one.

The city of Chang'an was lit up one by one.

Not just Chang'an.

Lights along the railway and on the roaring locomotives dispel the darkness.

The lights are along the coast and on the cliffs above the roaring waves, illuminating the way ahead.
