It was the emergence of steam trains that officially ushered in the steam age, and technological civilization made a huge leap.
In fact, Su Chen originally thought about building an internal combustion engine train, but considering the current technological level of Datang, he eliminated this idea.
Although he can redeem the manufacturing drawings of the internal combustion engine through the system, he may not be able to manufacture them.
Moreover, even if an internal combustion engine is barely built, fuel is another big problem.
How to dig out the oil and then refine it is another problem.
So, Su Chen took the next best option and chose the steam train.
Although steam trains are inferior to internal combustion engines in terms of kinetic energy, they fully meet the needs of this era.
The steam train's speed of 60 kilometers per hour is much faster than the so-called sweaty BMW!
In addition, the manufacturing process of steam trains is much simpler, so large-scale application is not a problem.
After the steam trains and rails are manufactured, both commercial trade and people's travel will benefit greatly!
Not only that, once the railways and steam trains are built, when a foreign war is launched in the future, the grain, grass and baggage can also reach the front line quickly. I wonder how much manpower and material investment can be saved!
The benefits are endless!
"System, redeem the steam train manufacturing blueprints!"
Just as he was told, Su Chen immediately redeemed the steam train manufacturing drawings from the system.
Seeing that his wealth had shrunk by more than half in the blink of an eye, Su Chen's heart ached!
However, when he saw a drawing appearing out of thin air on the table, Su Chen immediately beamed.
"It's true that life is unpredictable. The big intestine wraps up the small intestine."
"Originally I just wanted to get rid of the locusts, but I didn't expect that it would cause so many troubles."
"Just manufacturing a railway track in the early stage is estimated to be enough for the people watching the city to work for a year."
"Of course, the cost of purchasing so much steel is an astronomical figure. Let Li Er pay for it. After all, this is a good thing that benefits the country and the people. I believe he will be happy to support it."
Looking at the drawings in front of him, Su Chen couldn't help but smile.
If all these steel materials are purchased with your own money, you will definitely be unable to stand still.
He has already made a rough calculation. Just building a railway from Chang'an City to the frontier can wipe out all the remaining wealth of his family!
Since he couldn't come up with so much money himself, he had no choice but to help according to the old rules and make an idea to His Majesty Li Er.
Anyway, His Majesty Li Er has made so many contributions to the development of the Tang Dynasty, so it doesn't matter so much this time.
…
Thousands of miles away, Chang'an City.
"A sneeze! A sneeze!"
His Majesty Li Er, who was enjoying the flowers with Empress Changsun and her two precious daughters in the Imperial Garden, suddenly sneezed several times out of control.
"Your Majesty, the weather has turned cold recently and you accidentally caught the windchill?"
Queen Changsun expressed concern.
Princess Changle said: "Yes, Dad, you have been busy with government affairs in recent days and have not had a good rest."
"well……"
His Majesty Li Er sighed softly, shook his head and said: "Sure enough, time is not forgiving, you will eventually grow old."
"When I led troops to fight in the past, even if it was freezing and snowy, I could cook wine with Shu Bao and the others in the snow, but now it's not winter yet..."
His Majesty Li Er felt a little unmotivated and felt a sense of heroism.
Empress Changsun smiled and said: "Your Majesty, what are you talking about? No matter what, we are also normal flesh and blood. The weather has suddenly changed, and it is normal to feel a little uncomfortable."
"Moreover, Your Majesty is now in good health, so why should you say you are old?"
Queen Changsun chuckled.
After hearing Empress Changsun's words of comfort, His Majesty Li Er felt much better.
"Haha, the snow has arrived suddenly, and the weather has changed really fast. Why don't we have hot pot tonight to ward off the cold."
His Majesty Li Er laughed loudly.
"hot pot!"
"Okay, Si Zi hasn't had hot pot for a long time!"
Xiao Sizi was the most excited when he heard the word hot pot.
"Let's go, it's getting late now."
After saying that, His Majesty Li Er took his wife and children to the Li Zheng Hall.
While His Majesty Li Er and his family were enjoying hot pot happily, Su Chen, who was in the north, had already written a letter about his plan to build railway tracks and build a steam train, and had people rush to send it to Chang'an.
An indescribable energy once again enveloped His Majesty Li Er. I'm afraid His Majesty Li Er himself never imagined that his treasury had not been warm for a long time before he was once again concerned about Su Chen.
…
"My good Majesty, I hope you won't get angry when you read the letter. The reason why I did this is for the Tang Dynasty!"
Su Chen could already imagine the look on His Majesty Li Er's face after receiving the letter.
It is estimated that when he returns, he will be reprimanded by His Majesty Li Er again.
After making sure that today's affairs were taken care of, Su Chen left the study to eat, then took a hot bath and fell asleep early.
The next day.
Su Chen got up early and had breakfast.
Today, for the people watching the city, it is destined to be an uneasy day.
In these short two months, the people's lives have never been peaceful.
From the day the locust plague appeared until now, people have had an unreal feeling.
First, the crops and food were destroyed by locusts, and then the land was destroyed, making it impossible to cultivate for at least ten years.
Originally, the people slowly accepted these realities.
However, this sudden heavy snow really exploded the long-suppressed negative emotions in their hearts.
"If this snow could have happened a few days earlier, wouldn't all our land have been destroyed?"
"Yeah, now that it's snowing, the other two states can control the locust plague even without using the pesticides from the Protector. I really envy them."
…
In the square, the common people were talking to each other, and most of the expressions on their faces were loss and confusion.
After losing the land they relied on for survival, these farmers who had been honest for most of their lives really didn't know what to do.
Fortunately, although the people were melancholy and confused, they did not lose hope in life.
Just because the young man whom they respectfully call the "Guardian of the Country" has promised them that he will not allow the people to be displaced!
It was out of trust in Su Chen that although Su Chen said that the people would gather in the square at noon, the people still couldn't wait to come here early in the morning to wait.
When Su Chen heard about this, he suddenly changed his original plan and asked someone to prepare the carriage and go out directly.
