The big man has a living father

Chapter 251 (Big Chapter) Internal Combustion Engine!
The people of Chang'an City watched as a thermal power plant rose from the ground.

The towering chimney is very special.

At this time of year, if you stand on a high place in Chang'an, such as Bashang, you can see at a glance that there are many tall towers in the city of Chang'an.

Those tall towers are all water towers.

Every day, these water towers are filled using gravitational potential energy and human pumping.

Then there are the black chimneys coming out of the factories.

And now, a tall white chimney that is obviously different has been erected in the city. No one knows what it is used for, but everyone knows that it is definitely a big treasure.

Every time such a unique thing appears, it represents the advancement of science and technology and that Chang'an's prosperity will reach a new level.

It also means more jobs and better job opportunities with higher wages.

From the factory area where the white tower is located, many lines extend outward. These lines are lifted up by newly built tall concrete columns, away from the ground.

Some curious people ran to the nearest tall building and carefully observed what the line was.

After reading it, I kept silent, for fear of getting into trouble.

However, someone discovered that it was copper wire.

The public security in Chang'an City has improved greatly in recent years, but it is still far from the point where doors can be left open at night.

That night someone went up and tried to steal the copper wire.

That night, nearby residents learned that the human body can burn.

To the researchers at the institute, stealing high voltage electricity was incomprehensible, so they never thought that anyone would do this. They neither issued a warning nor sent anyone to keep an eye on it.

When the Dahan Daily published an article, it said that someone stole metal wires from Chang'an's infrastructure and was struck to death by lightning.

Because the time has not yet arrived, the power company does not want to announce the existence of electricity in advance.

The reason why the lines that are still under construction have electricity is because the power plant was built not just for show.

The research institute has established several new factories here, which require electricity to build.

For example, an aluminum extraction plant.

After the power plant was built, it began to supply electricity. The researchers were experimenting with the voltage of the lines and the stability, so they did not trip the gate.

In the pickpocket world of Chang'an, there is a horrible urban legend.

It was said that the research institute had mastered some horrible thing that could burn people instantly. The colleague who was roasted was not struck by lightning, but was murdered.

This actually gave the people working on the utility pole project some relief for a while.

The electric poles were being built in an orderly manner.

The stock trading center is also undergoing intensive transformation.

Everyone in Chang'an knew that the square outside the stock trading center would host the first science and technology expo in the history of the Han Dynasty.

Everyone is waiting for the arrival of this grand event.

……

On the west side of Chang'an, a new palace has been built.

The newly built palace here was called the New Xianyang Palace.

The old Xianyang has now changed its name and is called Weicheng, which stands alongside the former new city, old city and south city, making it easier to distinguish.

The reason why it was renamed Weicheng is because after the Wei River was changed its course, it is now right in the face of old Xianyang.

In the folk, people called that place Qincheng.

Outside the New Xianyang Palace, a luxurious complex of buildings rose from the ground.

Liu Che and Huo Hai strictly implemented the original strategy to build this area into a luxurious district and then sell it to civil and military officials, clan relatives and nobles.

In recent years, more and more relatives have come to Chang'an to do business.

Business is something that you can't let go of, so once you come here, you are a Chang'an citizen and you can never leave.

If you can't get away, you have to buy a house.

The clan members, especially those who were crowned as kings, had to buy a house that matched their status, right? That meant it had to be a big house.

A big house costs a lot of money.

Liu Che's new Xianyang Palace was built in the latest style and had electricity.

This place was originally Ling County, and now it has been completely demolished, with only the research institute and the old Huo Mansion left.

All other areas have been developed into high-end residential areas.

The emperor has moved here, so there is no problem selling the houses here. The reason why the houses here have not been sold yet is because the use of electricity has not been made public.

After the announcement, it will be announced that the mansion here is equipped with electrical wires and lights, which will be a major selling point.

Liu Che stood on the tall walls of the new palace, looking at the Jianzhang Palace in the distance and said: "I have more and more palaces."

"I have more than ten times more palaces than Qin Shi Huang. Ying Zheng is scolded every day. Will I be scolded in the future?"

Bu Shi bowed and said, "Your Majesty, future generations should be able to easily figure out why you built the palace."

Liu Che smiled and said, "Why did I build the palace?"

Bu Shi: "It's just a way to boost the economy. In the words of the Minister of Agriculture, it's a type of infrastructure. It's just that this type of infrastructure is only available to you, unlike other infrastructures that are shared by everyone."

"But from a certain perspective, the area where the palace is located has greatly alleviated the population density, green area and urban environment of the area. So in fact, for ordinary people, the palace is similar to a park that you are reluctant to enter because you have to pay an entrance fee."

After hearing what Bu Shi said, Liu Che's smile froze.

A park that you don't want to go to because it charges an entrance fee?
On the other side, Sang Hongyang seemed to have something to say, but he didn't say it in the end.

Liu Che: "Just speak your mind."

In Liu Che's small economic team, Bu Shi and Sang Hongyang have always been at odds with each other.

Bu's philosophy is to use economic means to guide people's livelihood and make people live better.

In Sang Hongyang's philosophy, the people are only a part of the economy. If there are benefits, then the people can naturally live a good life. However, if it is for the prosperity of the Han Dynasty, sacrificing the people is worth it.

Their theories are completely relative.

If Huo Hai had not changed history, Bu Shi would have been preparing to become prime minister and then resign in anger.

The reason why he resigned in anger was because Sang Hongyang's theory was completely incompatible with his.

For Liu Che, both of their theories were correct.

It's like sunshine and shadow.

Where there is sunshine, there is shadow. If there is no shadow, it is not that the sunshine fills the world, but that the sunshine has disappeared.

Therefore, Liu Che supported both of them and rose up based on their opinions.

The Han economy also rose along with their swings.

However, it is obvious that Liu Che prefers Bu Shi, who is older, more stable and more gentle.

Sang Hongyang was just pretending to be hesitant. When Liu Che asked him to speak, he immediately said, "Your Majesty, ten years ago, you alone occupied 80% of the building space in Chang'an. 80% of all the buildings in Chang'an were your palaces. But now, it's less than 5%."

As soon as Sang Hongyang finished speaking, Bu Shi immediately added: "Ten years ago, there were Lingxian and Luli."

Sang Hongyang immediately said, "But ten years ago, half of the land outside the city walls in Sanfu was your majesty's Shanglin Garden and palace complex."

What Sang Hongyang said is right.

If we regard the living space of Chang'an as a whole, then Liu Che occupied 80 percent ten years ago, and now he occupies about 4 percent.

Bu Shi: "Don't forget that your majesty's palaces were only four in the city and ten outside the city. If we use the size of a Jianzhang Palace as the area of ​​a palace, your majesty now has fourteen palaces in the city and thirty-three outside the city."

Each of these palaces is comparable to a Forbidden City.

Liu Che built forty-seven of them.

They are distributed in the former Chang'an Old City, the New Xianyang Palace, the Bashang Palace, the former Shanglinyuan Palace Complex, and near the current Caoyun.

these places.

In the past, building a palace required mobilizing hundreds of thousands of people, or at least 200,000, for forced labor.

Now, to build a palace like the one at that time, it would take about 10,000 people and if they paid them, it would be completed in more than a year.

The sensory quality of a palace today is actually better than before. The reason why fewer people use it is due to advances in technology and tools.

In recent years, whenever there was a situation where a large number of workers in Chang'an City could not find jobs, Liu Che would start to build "infrastructure" projects.

Including water transport, trucks, and the repair of the canal and the construction of Shanglinyuan.

The construction of the palace came second.

With the current number of workers in Chang'an City, if money is really available, Liu Che can really build a palace so big that "he would wake up in a 500-square-meter bed in the morning and pee in his pants before he can even run to the toilet."

But it is not necessary.

After listening to the two people's statements, Liu Che didn't care and smiled: "Although the proportion has decreased a lot, the number has skyrocketed."

"It's the same as what Huo Hai said about making Chang'an bigger. Although my share is smaller, the absolute amount has skyrocketed dozens of times. It's just that the palaces are not so exaggerated. I just don't need dozens of times more palaces."

With Liu Che's current wealth, if he really wanted to be criticized for wasting money and manpower, he could have simply built the entire palace from the New Xianyang Palace to the Jianzhang Palace into his own.

The question is, who will live there?
It was even so luxurious that the crown prince had a special palace for receiving guests, the empress had a special palace for embroidery, and Emperor Liu Che had a special palace for reading and writing.

There is a special palace for small court meetings and a special palace for large court meetings.

There are three offices for daily affairs, located in the city, south and west.

There are three places near Chang'an for cooling off in the summer, four for keeping warm in the winter, and four where you can see wild animals while sleeping.

If this construction continues, Emperor Liu Che will not know what to do with the palace.

Bu Shi said, "Your Majesty, you can try to build royal gardens and parks and open them to ordinary people."

"The Minister of Agriculture once proposed to build a wildlife park and open it to the public. This would also greatly arouse the interest of ordinary children in exploring the world."

Liu Che raised his eyebrows: "Really? Building a zoo..."

This is indeed the truth. If you like to raise rare animals and plants, others will definitely like to see strange things. If you love to see animals, you will definitely be interested in exploring the outside world.

In fact, Huo Hai had wanted to propose this a long time ago.

Because at present, many nobles in Chang'an City have a lot of rare animals and plants in their homes.

Some people even keep big guys like jaguars at home.

This is the Han Dynasty, not the Ming Dynasty or something. You won't be scolded for raising animals.

Moreover, the situation in the Ming Dynasty was also strange. Every minister had his own Leopard Room at home, and no one said anything for decades. But when Zhu Houzhao set up a Leopard Room, it immediately became evidence of his indulgence in fun and neglect of his job.

Even if this is really evidence of not doing your job properly, why don't you just control yourselves first?

The hidden reason behind this, of course, is the fear that future emperors would become interested in the external environment again and reopen sea transportation, replacing the smuggling that was secretly carried out by the civil service group.

In the Han Dynasty, Liu Che was too lazy to care about his ministers, and the ministers had no objection to Liu Che's actions.

Moreover, various animals are not yet at the level that requires legislative protection.

Therefore, Huo Hai also tends to build facilities such as parks and zoos to stimulate the interest of ordinary people in external exploration.

Besides, these things, as public spaces, can enhance citizens' sense of happiness.

For Liu Che, the land was in his hands, and the old house was basically in the hands of him and Huo Hai. As long as he wanted to renovate it, it would be easy to do so.

The only problem is that it is a bit difficult to transport the animals from overseas back to Chang'an.

However, building a palace can trick civil and military officials into buying new houses, but building a park or something like that is pure investment.

Liu Che thought about it carefully and nodded: "Go ahead and do it."

Now, after Liu Che has calculated how much money he has and how much money he can get from various places every month, he is no longer as stingy as he was before.

Now it seems that stimulating the economic cycle is much more important than killing two birds with one stone by plundering the officials.

Seeing that Liu Che didn't care about this matter, Sang Hongyang spoke again: "Your Majesty, many coal mines have been opened this year, and coal production has increased greatly. In many places, coal production may exceed demand. Should we promote power construction in other cities as well?"

Liu Che still attached great importance to this matter: "Let Chang'an try it out for a few months first. If there is no problem, then promote it to other cities, starting with the five capitals and three ports. As for other cities, wait a little longer."

Coal mining resulted in a huge increase in output, but Liu Che was well aware that the current population of the Han Dynasty was over 100 million, and if everyone really used electricity, this so-called increase in output would be equivalent to not being enough.

However, it is precisely because of this that we must be more determined to promote the development of electricity.

Because, according to the institute's calculations, even in garbage-fired power plants, the energy utilization rate is much higher than that of steam engines that also burn coal.

The coal burned in a 500,000 horsepower steam engine is used to generate electricity and drive motors that can produce 3 million horsepower!

In other words, the coal consumption of weaving 100,000 meters of cloth with a steam engine can now be made into ready-made clothes after weaving 100,000 meters of cloth. The textile workers and garment workers can also use electric lights in their own homes, and the entire factory can be powered by electric lights.

At the same time, electric lights were also introduced into the mines, which greatly increased the efficiency of miners and reduced the number of workers by half.

If the same number of workers is maintained, the output of deep mines will double.

This doubling of output means that while the output of garments has doubled, so many workers are able to live an urbanized and modern life.

Just the efficiency of electricity utilization can make such a big difference!

However, with the development and innovation of steam engines, energy utilization will definitely increase.

But the problem is that with the innovation of steam engines, electric motors and steam turbines will also be innovated, and the energy utilization rate may have a greater room for improvement.

……

Chang'an City is very lively again today.

A large number of people are going to the stock exchange center to join in the fun.

Normally, these people spend huge amounts of money here, leveraging the financial market and squandering capital.

And today, they all came to broaden their horizons.

The whole square was filled with noise.

Many exhibitions were just displaying things without any demonstrations, but they were still crowded with people.

Today, in this place, mysterious researchers are everywhere.

A large number of people are gearing up. In addition to the Royal Academy, people from other research institutes are also making preparations, they want to seize the opportunity to become famous overnight.

Huo Hai also arrived here early today.

Huo Hai’s house also has an exhibition stand.

Princess Wei Chang wanted to exhibit the difference between her hybrid peas and ordinary peas.

The exhibition features North American bird specimens and fossilized dinosaur skeletons discovered in Dahan.

Huo Hai did not interfere with their research on fossils. Currently, the academic community only speculates that these were left by prehistoric creatures. As for why the bones became petrified and have no biological activity, they are still studying it.

Dinosaur bones often appear together with chalk and are temporarily called Cretaceous megafauna, but have not yet been specifically named.

As soon as Huo Hai arrived, he was surrounded.

Jiang Buyi said directly: "The Grand Minister of Agriculture is not the protagonist today. The Grand Minister of Agriculture will not accept any inquiries, and has no time to instruct anyone. The Grand Minister of Agriculture wants to see the exhibition!"

After hearing what Jiang Buyi said, everyone left very tactfully.

When Huo Hai is happy, a few pointers can certainly help people ascend to heaven, but when he is unhappy, a few pointers can also cause people to be reduced to ashes.

Of course no one would dare to take advantage of it.

After everyone dispersed, others saw that there were few people around Huo Hai, so naturally they wouldn't have the courage to surround him.

Huo Hai is here today to get a basic understanding of the industry.

Just like what Huo Hai said at the beginning, many research projects are a matter of luck. It does not mean that high investment and high-level researchers will definitely produce results.

But if there are enough researchers, someone might get lucky and stumble upon something.

If this is extended to various types of research, the probability of a blind cat catching a dead mouse will be extremely high.

So, there will definitely be a lot of new discoveries today.

How could Huo Hai not put in a little more thought?
Soon, Huo Hai saw something made of pure metal structure.

Walking forward, Huo Hai asked, "What is this?"

The person being questioned said excitedly: "This is a cooling device!"

Huo Hai tilted his head and took a look.

The man explained: "If the air expands, it will become hot, and if it contracts, it will become cold. My mechanical structure can compress the input air and blow out cold air."

Huo Hai was stunned for a moment. This didn't look like the structure of a compressor.

Huo Hai thought for a moment and said, "Turn it around."

The man hesitated a little: "How can human power do this?"

"At least... find me a donkey?"

Huo Hai: "There is a steam engine over there, let's try it."

Huo Hai was not sure whether this thing was a compressor, or something like the industrial-grade super cooling structure he had seen in short videos before.

So it’s a good idea to give it a try.

If there is such a thing as a compressor, then air conditioning isn't far away, right?
Huo Hai remembered that he learned when he was in school that air conditioning was first invented to be used in the unstable printing environment.

At present, the Han people have not encountered this problem, which may be due to the different structure of the printing press. However, if the air conditioner is invented, it will definitely have many great uses.

And compressors also meant that refrigerators were possible.

Although the cold chain is still a long way to go, after all, the beginning is always the hardest.

Seeing that Huo Hai was interested in a research project, everyone else followed suit.

A large group of people followed and searched for a long time on the steam engine before finding a shaft structure of suitable size.

After the connection was established, everyone waited.

This thing sucks in the external hot air when the steam engine is burning on one end, and starts blowing air on the other side.

There is no such thing as delay with this kind of mechanical structure. As long as it starts turning, it will take effect immediately.

Huo Hai reached out and touched it.

Cold wind!

"What's your last name? What's your first name?"

The inventor of the compressor was confused by the question, then realized that his invention had been noticed and said excitedly: "I don't have a last name, my name is Qi."

Huo Hai patted Qi on the shoulder and said, "From now on, just believe in the cold. When people feel the cool breeze on hot days in the future, they will definitely remember you."

"Then my name is Leng Qi?"

Huo Hai thought for a moment and said, "Why not just call it Lengqi? It's up to you whether you want to change the name or not. As for the surname, wait for His Majesty to give it to you."

Leng Qi nodded excitedly.

Huo Hai: "Are you interested in studying refrigeration equipment at the research institute?"

"Refrigeration equipment?" Leng Qi did not associate refrigeration equipment with compressor.

Leng Qi thought that the current steam engines and boiler rooms are too hot. If we have this compressor and continue to improve it, we will definitely be able to make the boiler room less hot in the future.

But his idea is definitely not going to work.

Huo Hai: "Since compressed air can be used for cooling, isn't it normal to lower the room temperature from over 30 degrees to over 20 degrees in summer? This is not just for enjoyment, but also for various scientific research institutions, manufacturing institutions, and special environments. Also, if the temperature is further lowered, can we simulate winter weather in summer and directly freeze food and medicine? Or even more things?"

A researcher nearby said: "There are also frozen iron eggs, which will make bearings easier to manufacture! We can't freeze iron balls in the summer, so we can't manufacture high-precision bearings. The bearings we use now are all made in winter. If we can simply actively cool them down, we can manufacture bearings on a large scale at any time!"

If this comes true, the straight-ahead train is really coming!

You should know that today's bearing manufacturing uses thermal expansion and contraction at the same time to create a size difference between the sleeve and the marble, and then drives them in with a hard impact.

The difficulty of this method is not heating the outer structure, but freezing the inner structure.

Now there seems to be hope for a solution to this problem.

Many researchers around him were inspired: "If the room temperature can be controlled, the environment for culturing drugs will be much more stable. Perhaps large-scale extraction of penicillin will be realized ahead of time!"

“If you can freeze meat, and do it on a large scale, wouldn’t it be much easier to transport meat?”

Seeing how heatedly they were discussing, Huo Hai didn't say much. He just asked Jiang Buyi to arrange for Leng Qi to be brought to the research institute.

Being able to develop a compressor independently means he is definitely a mechanical genius.

With the assistance of more professionals and more cutting-edge technology, he may be able to make air conditioners soon in the future.

With this invention as a foundation, Huo Hai is very confident about today's Han Expo.

Soon, Huo Hai saw a strange mechanical structure.

The structure is like a... tuba, a musical instrument with a pulling structure. Waga hung a gas tank and then added an air bag bellows.

Huo Hai felt that this thing looked familiar, so he looked at it a few more times.

But I can't see why.

Because there was no one at the booth, Huo Hai looked for a while and prepared to leave.

At this time, a man rushed over in a hurry: "Grand Minister of Agriculture, Grand Minister of Agriculture!"

Seeing that he was acting recklessly, Jiang Buyi blocked his way directly.

Some guards who had been following secretly also appeared and stood in front.

The man shouted: "This is my invention. Let me demonstrate it to you, the Minister of Agriculture!"

Huo Hai: "Let him come over."

Only after the person was released did Huo Hai see clearly.

This guy looks a bit dull, like a 21st century college student, but in person you can clearly see his bulging muscles, giving him the feel of a mechanic.

It's like someone who is tampering with motors every day.

Huo Hai looked at him and spoke up: "Grand Minister of Agriculture, my name is Le Lu, and this is something I invented."

Le Lu pointed to a section of the structure and said, "This is a diesel gasification pipeline, designed by General Motors. My invention uses part of their patented technology."

Huo Hai nodded: "It is normal for a complex invention to use some of other people's technology. As long as your invention is good and useful, it's nothing. It's nothing more than paying them after mass production."

Le Luqi breathed a sigh of relief when he heard Huo Hai say that: "I also used the airbag structure launched by the research institute last year to send air to the pipes."

Air supply, diesel gasification?
Huo Hai pinched his chin.

Jiang Buyi: "This is a filling body, this is where the air is delivered, and the other pipe is for high-temperature gasified diesel... Could this be a combustion mechanism that burns gasified oil?"

Jiang Buyi reacted immediately.

Since this thing is closed, there must be other structures inside it, otherwise Le Lusao would not have been able to seal it up casually.

Could this be...

Le Lu: "When I was studying mechanical structures, I discovered that most of the heat from coal combustion is actually inside the combustion chamber."

"The heat used by the steam engine is actually just a small amount of heat dissipated outside the combustion chamber, which heats the water and generates power."

"When water is heated, it vaporizes and expands, and can be used as a power source."

"But if it is oil and gas itself, it will expand after combustion, and this happens inside the combustion chamber, so the kinetic energy should be much stronger than steam."

Huo Hai: "Internal combustion engine?"

Le Lu nodded vigorously: "Yes!"

"It's just that each combustion requires ignition. But we can use the inertial structure to use the inertial activity cavity after each combustion to draw in new air mixed with new vaporized oil, and then ignite it again."

"Except for the ignition structure, the rest of the structure was easy to complete."

Huo Hai was stunned.

I didn’t expect someone would actually develop an internal combustion engine so quickly!
However, if there is no breakthrough in the ignition structure, this invention is equivalent to no invention at all.

Le Lusao: "However, this shaft rotates four times to complete a cycle, which requires a complicated ignition device. If another structure is used, it will not be necessary."

Huo Hai: "Four-stroke, two-stroke? Have you successfully invented the two-stroke? Can it be used?!"

Le Lu was stunned for a moment, then his face darkened: "Could it be... Grand Minister of Agriculture, has someone at the Institute already invented the internal combustion engine? I thought I was the first."

Huo Hai shook his head: "No one has invented the internal combustion engine yet, and no one has studied it. It's just that I... have thought about it sometimes."

When Le Lu heard that no one had studied it before, he immediately became interested and hurriedly introduced: "My two-cycle... according to what you said, the two-stroke internal combustion engine has been designed and can be used."

"My internal combustion engine can replace a small steam engine!"

It is more than just a replacement for small steam engines!

This is a wrong path.

Huo Hai: "There is no future for the internal combustion engine to replace the small steam engine. Today we will announce a new machine to replace the steam engine."

"And your internal combustion engine, which is naturally small, should be installed on vehicles to greatly improve transportation efficiency!"

Le Lu was researching these things on his own and was completely clueless about cutting-edge technology. He also didn't know that automotive research was a key project in the institute.

Now that the internal combustion engine has been invented, it is no problem to at least make a classic car or tractor.

Of course, it may take some time to actually research it out. After all, this thing may not be very powerful with a single cylinder, and the structure that uses air bags to input air is obviously unreliable.

After replacing the latest metal materials from the research institute and using rubber and other things, we will see whether the mechanism he invented needs to be optimized and whether it can be adapted to the current chassis. It is estimated that this process will not take too long.

Unexpectedly, Dahan’s electric motor and internal combustion engine were announced to the public on the same day!
The discovery of this invention made Huo Hai much more excited than the discovery of the air compressor.

This is an internal combustion engine!
The chassis of Dahan's car has always been under research, and its mechanical structure is very advanced.

At least it's the level after World War I.

Now that I have a small heart, it's almost like I have life!

The cars manufactured by the Han Dynasty should be much better than the internal combustion engine cars of the first thirty years of the previous life.

After all, car technology in the first few decades of the previous life was completely monopolized, and a group of people developed cars behind closed doors.

In Dahan, a large number of people are studying various structures on the chassis, and even trams have been around for some time.

The way Huo Hai looked at Le Lushao changed.

Le Lusao still doesn't understand what epoch-making invention he has made.

Huo Hai only said: "Perhaps everyone will have a car in the future, and the car will be equipped with your engine, the internal combustion engine."

"Of course, a two-stroke engine can't do this. You have to invent a four-stroke engine without an ignition device, and then work with your colleagues at the research institute to figure out how to adapt it to cars and boats."

Even... on a plane.

The internal combustion engine is about to come out, so how far can the airplane be?
After discovering the internal combustion engine, Huo Hai was no longer interested in anything else, but he still chatted with Le Lusang while checking out other technological achievements.

Wow, the results are really rich!

Some people independently used chemical technology to extract resin from coal tar.

Although this is something that the research institute has already accomplished, the technology has not been passed on to others and was independently researched. This is enough to show that this person has talent in this area and is another promising talent.

Some people have also developed a double-sided hinge structure lock.

Someone invented a skateboard.

Someone came up with a watering can structure!
What Huo Hai didn't expect the most was that when Lu Bode returned to Chang'an, this guy actually set up an exhibition hall to demonstrate the pasteurization method!

But it is not called this name now, it is called the Lubode low-temperature disinfection method.

As he walked along the way, Huo Hai never expected that the Han Dynasty's technology had developed to this level.

Although a lot of things are still in the old era, the cutting-edge technology has been explored very deeply!
And these are just the appetizers for today's Han Expo.

As the sky gradually darkened, the excited crowd's excitement about technology turned into excitement about the dinner.

Liu Che will be here in person today, so everyone is of course very interested.

But they didn't expect that something even more shocking was about to come!

(End of this chapter)
