The Lingqi locomotive moved forward indomitably, and soon disappeared from the sight of the onlookers.

Not long after, the carriage and the knight returned to the station, shaking their heads and explaining that they were completely lost.

The onlookers were in an uproar immediately, the Lingqi locomotive was faster than galloping horses, and its carrying capacity far exceeded.

The expressions of the crowd were different, and the citizens of Chang'an, who were just watching the excitement, looked amazed.

Merchants engaged in bulk commodity trading were overjoyed,

Only the coachman, Lifu and crew members on the edge of the crowd were a little uneasy, whispering among themselves, worried that the Lingqi motorcycle would take their jobs.

After more than half an hour, the iconic clanging sound came from afar again.

The aura locomotive coming in the opposite direction slowed down slowly with billowing steam, and finally stopped.

Su Feng smiled and got off the front of the car, greeted the laborers, opened the compartment, and took out the goods from inside.

The crowd of onlookers could see clearly that when they left, the goods in the carriages were grain, oil, rice noodles, cloth, silk, tea and wine.

However, when they came back, there were logs, bricks, medicinal materials, spices, fish catches and so on in the carriage.

More importantly, there is also a plaque of the Tongguan Inn.

The crowd exclaimed, Tongguan is more than 80 miles away from Baqiao, and it will take at least three hours for the carriage to go and run, and the horses have to be changed in the middle.

And the spiritual locomotive only took half an hour?

In this way, from Chang'an to Luoyang, wouldn't it be possible to travel from morning to evening?

Su Feng patted Ou Zhiyuan's shoulder with a smile, and asked his disciples to check the condition of the vehicle, record the data,

He himself brushed off the dust from his clothes, and walked briskly to a restaurant.

In the pavilion, the emperor, prince, prime minister and ministers had fluctuating expressions, obviously having doubts.

"Dr. Su,"

Emperor Yu said in a deep voice: "What is the speed of the spiritual energy locomotive? Is there any loss?"

"Return to Your Majesty,"

Su Feng smiled slightly. He had already written these details in the previous memorial. The emperor naturally knew, but he just took this opportunity to tell the ministers.

"Baqiao is eighty-six miles away from Tongguan. There is a total distance of one hundred and seventy-two miles to go back and forth, and it takes five quarters of an hour. One quarter of an hour is used for loading and unloading goods at Tongguan station. The actual travel time is four quarter of an hour.

As for wear and tear, the aura machine uses the aura of heaven and earth as its power, and the consumables used are just parts that need to be replaced due to mechanical wear and tear, almost none. "

Su Feng paused for a moment, took a panoramic view of the astonished expressions of Shang Shu Pei Su, Zhong Shu Ling Xue Ji and others, and continued: "This is the result of the spiritual locomotive not running at full speed.

At full speed, the Lingqi locomotive can drive up to 480 miles per hour. "

In the court speech Baidi Caiyun, thousands of miles of Jiangling will be returned in one day.

This poem immediately appeared in everyone's minds, a thousand miles of Jiangling will be returned in one day? Two hours is enough!

This is the real day and night.

"What about the load?"

Shangshu servant Pei Su took a deep breath and asked in a deep voice, "How much cargo can you carry?"

"The load of the carriages depends on the quality of the rails. During the journey just now, one section of the carriages contained less than 12,000 jin of goods. But in the forging workshop of the Academy, we have tested that it can hold up to 80,000 jin."

Su Feng was satisfied with the drastic changes in the expressions on the faces of the ministers, and added: "And for such a carriage, the Lingqi locomotive can pull six seats at a time."

It is equivalent to being able to transport 480,000 catties.

Most of the ministers here are from the bottom county magistrates, step by step. A series of numbers were calculated in the blink of an eye.

There are three million people in Chang'an City, which is equivalent to three million mouths waiting to be fed. Millions of catties of food are eaten a day.

There is an endless stream of horse-drawn carriages and cargo ships entering the city of Chang’an every day.

The whole city is like a monster that can never be filled, absorbing supplies from all directions without stopping for a moment.

So much so that every winter, the Zhenfu Division needs to send monks to smash the ice on the Wei River and other rivers to make the ships barely navigable.

If there are a few more Lingqi locomotives, then these vehicles alone can fill the stomachs of Chang'an people.

Let the twisted rope hanging around the neck of the bureaucrats in Chang'an be loosened.

"What about the cost?"

Prince Li Si asked: "Such a huge monster must not be cheap, right?"

"Reporting to Your Highness, the parts used in the aura locomotive are extremely complicated and cannot be made in ordinary workshops, and can only be made by using the iron melting and iron casting techniques of the academy."

Su Feng had been prepared for a long time, and took out a thick stack of blueprints from his pocket, "The spiritual energy machine itself needs 600,000 guns.

The boiler, steam engine, frame and other parts of the locomotive need 250,000 guns. Tin carriage plus wheels, one hundred thousand.

In addition to the bits and pieces of seats and benches on the car, the cost exceeds one million guan. "

"How many?!"

Even with certain psychological expectations, this figure still far exceeded the expectations of the ministers.

10,000 Guan can buy a mansion in Chang'an, build a sailing boat,

A million strings is more than enough to start a small war.

"This is just the price of the Reiki locomotive itself. The real big deal lies in the rails."

Su Feng said patiently: "A three-foot-long rail weighs about thirty-six catties, and a set of rails weighs seventy-two catties.

The price of iron in Chang'an today is 40 Wen per catty.

That is to say, two thousand eight hundred and eighty wen of iron is used for every three feet.

For one mile of railway, the iron alone costs 1,440 guan. If you want to repair to Luoyang, it will take 600 miles, and you will need a total of 860,000 guan. It takes 3.45 million guan to repair to Dengzhou. "

A series of numbers shocked the expressions of the ministers, especially the Minister of the Ministry of Revenue, who was in charge of taxation, and his face turned pale.

".And, it's just an optimal cost."

Su Feng seemed ignorant, and said to himself: "In reality, the terrain is tortuous and undulating. If you encounter mountains, you need to detour, and when you encounter rivers, you need to build bridges. The construction cost of real railway tracks may need to be doubled. .”

"Wouldn't the wooden track work?"

A minister couldn't help asking: "I heard that the mines use wooden tracks to transport ore, and at most they are covered with a layer of iron."

"no,"

Su Feng shook his head and said, "The wooden rails are too light and soft. It's okay to carry the ore-loading trolleys, but it can't carry the big ones. There will be a risk of derailment."

Prince Li Si knew Su Feng's character well, so he asked helplessly, "Dr. Su, as the inventor of the spiritual energy locomotive, why don't you speak up for your own invention?"

"Hehe, report back to Your Highness, because there is no need."

Su Feng smiled and said: "The cost of the spiritual locomotive plus the rails sounds too high and unacceptable at first glance, but as long as you calculate and measure it, you can come to the conclusion that it is far superior to horse-drawn carriage and river-sea shipping."
