Ask Sword

Facts have proved that when the State of Yu is fully exerting its national power, there are no difficulties that can stop it.

Carloads of ore were transported out of the mine, and the forge in the workshop erupted with flames day and night, melting the molten iron into steel. Thousands of laborers, like ants, were busy working in the mountains and forests, cutting down trees, Dig roads and lay rails.

For this project, the State of Yu mobilized a huge amount of resources. The state capitals dispatched more than 100,000 laborers, and the Ministry of Light and Industry consumed tens of thousands of talismans of different grades to excavate mountains and gravel.

Schools such as Xuegong and Luli Academy also sent a large number of teachers and students to dig caves and tunnels and build bridges in canyons with magic.

Although as the project gradually progressed, the construction cost doubled again and again,

But after a section of railway is built, it can be used quickly, and the rail steel produced in the workshop is continuously transported to the front line of construction by using the aura locomotive.

In this way, it is built and used at the same time. In less than three months, a railway connecting Chang'an and Luoyang has been completed.

For this reason, the imperial court set up a new department in Shangshu Province, parallel to the six departments, to coordinate and manage railway matters. Su Feng, who was not interested in being an official, was finally given the position of servant, and his title was promoted, and his disciples also received official positions or rewards.

Of course, it is impossible for a railway to have only one locomotive running. Xuegong worked overtime and urgently built two trains. They will travel on the railway at a distance and stop at stations set up by state capitals along the line. Both cargo and people.

With fiscal revenue, railway operations are no longer simply burning money. The imperial court quickly formulated a new plan to build railways in various state capitals until they spread all over the country of Yu.

The state capitals along the railway have gathered more manpower and materials, and built more restaurants, teahouses, mansions, warehouses, and workshops, providing more job opportunities.

Conversely, newly built workshops can use railways to sell goods to distant places and continue to expand. Form a virtuous circle.

late autumn.

"If the state is a giant beast, the railways are its blood vessels."

Li Ang picked up a pen and wrote a sentence on the scroll, then turned his head and looked out the window at the getting darker sky.

At this moment, he was sitting in the locomotive carriage driving back to Chang'an from Luoyang, opposite He Fanshuang who was quietly flipping through books.

Luoyang has always been the eastern capital of the State of Yu. Due to the rise of the Li family in Guanzhong, the control over Guandong is relatively weak. In the early Yu period, emperors of all dynasties often visited Luoyang in person to strengthen their rule over the east of the empire.

And every time the emperor travels, he will bring a large number of nobles from the clan, court officials, military messengers, and even common people's business travelers. This custom has continued to this day.

After the completion of the railway, the traffic in Chang'an and Luoyang became more convenient and efficient. Li Ang and He Fanshuang, as representatives of the outstanding disciples of the academy, visited and studied at Lizheng Academy in Luoyang for a few days, and are about to return now.

"laugh!"

There was the sound of steam erupting outside the carriage, and the train stopped slowly. Through the glass windows, one could see the brightly lit parking station and the passengers on the platform carrying large bags and getting on and off the train.

Traveling far away in this era is really hard. After riding a horse for a few days, my muscles and bones are painful, and my face and head are covered with dust.

Even riding in a carriage is not much better.

But taking the train is completely different. The distance is thousands of miles, and it is not only fast, but also sits safely, not afraid of wind and rain. For this reason, many people are willing to spend more money to buy tickets.

Some government servants in uniform, holding tin horns, shouted on the platform, "It is strictly forbidden to carry fuel, burning appliances, candles and other contraband on the train. Swords and weapons must be handed in in advance."

On the flat ground outside the platform, there are small stalls selling newspapers, food, tea, etc. The smell of fireworks is strong.

In a trance, the once noisy train station in the memory of the foreign world coincides with the scene in front of me.

"What are you writing?"

Maybe it was disturbed by the noise outside the window, He Fanshuang raised his head from behind the book and asked calmly.

"My impressions after visiting Luoyang."

Li Ang replied. Since Mosi lost control, he also started to write a diary, recording his daily mood changes, and beware of alienation objects changing his mind.

Of course, it definitely does not involve the memory of the other world.

"How should I put it. Lizheng Academy is more rigid than I imagined. The rules are stricter."

He paused, and said casually, "I heard that ten years ago they had separate campuses for men and women."

The experience of Lizheng Academy and his party cannot be said to be good or bad. The atmosphere there is more like that of the Imperial College, without the looseness and freedom of the academy.

Moreover, when the local students received Li Ang and He Fanshuang, there was not only a little admiration for outstanding people among their peers, but also the reserved pride of being a native of Luoyang, the eastern capital, who was unwilling to be looked down upon by visitors from Chang'an. Their attitudes were complicated and subtle.

Let's just say he's pretty young.

"Yeah. But their research on science and symmetry is very interesting."

He Fanshuang picked up a publication from the table and said, "Especially the recent Shensha Yunlu."

Yunlu, this kind of ancient talisman originated from witches, is now engraved by Su Feng on the metal plate of the spiritual energy machine, which is the core of the spiritual energy machine.

Since Su Feng took out the aura locomotive that changed the situation in Yu State, all forces have been acting.

The spies of Zhou State and Jing State are intensively collecting information;

The local state capital of Yu State mobilized contacts, hoping to influence the imperial court and build a railway locally;

The aristocratic families are keenly aware of the imperial court's firm determination to promote the construction of the railway, and they are all a little uneasy-once the railway is completed, the connection between the locality and the imperial court will become closer, and the production space of the aristocratic family will be further compressed.

The wealthy merchants and workshop owners actively contacted each other, hoping to use the aura machine for business as soon as possible. Whether it is textile, sewing, or papermaking, smelting and so on.

As for Neo-Confucian scholars from all over the world, they are also working hard to study the few papers, trying to keep up with Su Feng's research progress.

"What do you think?"

Li Ang asked.

He Fanshuang is a real genius. Apart from majoring in fencing and talisman, she is also studying Neo-Confucianism, arithmetic, rhythm, painting, and poetry.

In the words of the newspapers and periodicals, he is well-versed in classics and history, and he is good at poetry and painting.

Especially in the fields of mathematics and astronomy.

After the telescope was invented, all physicists used it to observe the stars, and soon came to the conclusion that the earth revolved around the sun in the process of autobiography, the moon does not emit light but reflects sunlight, etc.

And calculated the specific trajectory of celestial bodies, and even guessed that light also has speed.

And He Fanshuang went a step further on this basis,

She discovered four satellites of Jupiter with a telescope. After a long period of observation, she found that the orbit of one of the satellites was close to the orbit of Jupiter around the sun.

So sometimes, that moon will circle behind Jupiter and disappear in telescopes.

She recorded the time each time the satellite disappeared and reappeared,

Finally, it was found that when the earth was far away from Jupiter, the difference between disappearance and appearance time was seven minutes longer than the approach time (recorded by Su Feng clock).

Substituting this number into the distance between the Earth and Jupiter, the speed of light can be blurred.

The entire observation process took her two years.
