"What new things did you find again? Come and show me."
Princess Yiguang took the drawing over with great interest.
Ren Ning smiled.
Although this eldest princess has a noble status, she is actually approachable. When facing people close to her, she will call herself "I", otherwise she will be me.
"Qing'er." After greeting Huo Qing, the grandfather and grandson looked through the drawings carefully together.
"Your Highness, this is called a crane." Ren Ning introduced.
"Crane?" The grandfather and grandson looked at each other, a little confused.
Ren Ning felt relieved when he saw that their expressions were relaxed and normal.
Except for the eldest son Huo Qing, almost all the men in the Zhenguo Palace will go to the Yanqi Fortress in the west to guard the border when they reach adulthood.
Now the epidemic may have broken out in the fortress, and the Xiliang army outside the fortress was marching eastward. He thought that the town government would be in chaos.
Only then did they bring the crane or the combination pulley over, hoping to divert the attention of Princess Yiguang and the others.
It turned out that my worries were unfounded.
Think about it too.
As soon as they got married, Princess Yiguang accompanied her husband to conquer Nanfeng, killing the king of Nanfeng and surrendering. Later, she helped the mediocre Emperor Changxing ascend to the throne amidst the bloody storm.
She had never seen any big storms or waves.
"Boy Ren, I can't understand what you drew." Princess Yiguang smiled kindly, without any embarrassment at all.
She asked: "What is this crane used for?"
"That's it." Ren Ning first explained in detail what happened before Zhennanguan attacked Song Dingcheng.
Finally, he said: "As the name suggests, this crane allows people to easily lift heavy objects for easy loading, unloading and final assembly."
"So powerful?" After all, he was a top-notch general who had led troops. Princess Yiguang was indeed very interested. "Then if one person uses it, how much can this crane lift?"
"If it is built well, it will be absolutely no problem for any ordinary person to lift a heavy object weighing 10,000 to 20,000 kilograms." Ren Ning laughed.
laugh!
Grandfather and grandson both took a deep breath.
The last Wu champion was a strong man who was said to be able to lift a thousand kilograms. Princess Yiguang once saw him lift a cauldron weighing more than a thousand kilograms with both hands.
That is already a rare person in the world.
And this machine made up of a bunch of wheels can actually allow ordinary people to lift a weight of 10,000 to 20,000 kilograms?
Princess Yiguang gave Ren Ning a strange look.
If this guy hadn't brought out telescopes, raincoats, rubber shoes, wheels and other unexpected things before, otherwise she wouldn't have believed it.
"Grandma," Huo Qing couldn't help but say, "This is a good thing. Why don't you let the Ministry of War or the Ministry of Industry make one first and try it out."
Ren Ning smiled slightly.
He also wanted to build one quietly first and then shock the world, but it was basically impossible in reality.
Iron itself is a strategic material in short supply. The whereabouts of every pound and piece are closely watched by people in the government.
In addition, there was a major earthquake in Qingshi County last year, and countless mines were destroyed, and few skilled miners were able to escape.
Pig iron was already in short supply, and now it is even more tense.
Even the Ordnance Department is prepared to be unable to supply weapons and equipment to major legions and local garrison troops in a timely manner in the next few years.
Ren Ning had learned about these situations in Yingpan's letters and knew them well.
If others were fine at the Yingshan Camp, Wei Junqian would probably try it out anyway. If Ren Ning exaggerated or exaggerated, the worst he could do was to be melted down.
At this time, Ren Ning was in the imperial capital. Although his name had become famous recently, he still had little foundation.
If he wanted to find a blacksmith shop to secretly build the crane on the drawing, it would be basically impossible.
Because no blacksmith has enough iron to make it. And even if the blacksmith has enough iron, he would not dare to make it.
Fortunately, I know the eldest princess in front of me.
"Qing'er, the four treasures of the study." Princess Yiguang ordered.
"Grandma, your grandson will be prepared for you soon!" Huo Qing was overjoyed.
After a while, Princess Yiguang wrote a letter.
"Boss Ning, take this letter to Luo Ken, Minister of Industry."
"Summer floods are coming soon, and the Ministry of Industry is busy repairing river dams and post roads that were damaged in previous years. The progress is just slow, so they should be interested in this crane."
The most important thing is that Luo Ken is the grandfather of the third prince Chen Xiuzhu.
Luo Ken knows the capabilities of Zhenguo Gongfu. For the future of his grandson, he will definitely try his best to build the crane.
cough!
At this time, Huo Qing next to him coughed lightly.
"Grandma, my grandson once overheard friends talking about the court meeting."
"The court meeting?" Princess Yiguang frowned.
But she knew that her grandson would not be innocent, so she asked: "What's the matter?"
Huo Qingxiao: "It is said that in recent court meetings, courtiers have frequently proposed building a post road from Misty County to Qingshi County. Your Majesty is considering it, and it seems that nine out of ten of them will agree."
Mist County and Bluestone County?
Ren Ning next to him thought about it for a moment and quickly reacted.
Qingshi County is a famous mountainous area, known as the land that is not even three feet flat.
Almost all of its post roads leading to the outside world are built among the steep mountains of Chongshan Mountain. Last year, there was a big earthquake, and all the post roads out of the county were broken to pieces, making it almost impossible to repair.
Now the entire Qingshi County is almost in ruins. Even if iron ore is dug in the future, it will probably be difficult to transport it.
Since the east-west post road cannot be repaired, building a post road from Mist County in the north is a feasible solution.
only……
Ren Ning shook his head silently.
There are unfathomable swamps everywhere in Mist County. It is not easy to build a post road that can carry ore.
I don’t know how much manpower and material resources it will cost.
The only good thing is that in this era, ordinary people need to perform military service, but it does not cost the national treasury too much money.
Princess Yiguang came back to her senses and glanced at Ren Ning.
"If the crane you built actually works, maybe this road can be built much faster."
Filling the swamp requires a lot of stone and soil, and the crane comes in handy.
"Your Highness," Ren Ning stood up and bowed deeply, "I have an unkind favor."
"So out of touch!" Princess Yiguang waved to Ren Ning to sit down. She asked with a smile: "What on earth is going on?"
"Thank you, Your Highness!" Ren Ning sat down obediently.
"Last year when I was sending the deceased back to his hometown, I passed by Laigu County..." He told the miserable situation of the people in Laigu County selling their sons and daughters.
"If you want to find guards to build the north-south post road in Misty County, can you suggest to His Majesty that the people of these western counties should be given priority?"
Just give them a way out temporarily.
Although there will definitely be many tragedies like Meng Jiangnu crying at the Great Wall when building such a big project, it is still better than letting so many people starve to death in their hometowns.
sigh!
Princess Yiguang's face darkened, "I will try my best."
Most of the disciples of Zhenguo Duke's Mansion are guarding the border at Yanchuo Fortress. Every year, many people go back and forth between the fortress and the Imperial Capital.
She didn't understand the tragedy along the way.
It was just a sentence that women were not allowed to correct, so Princess Yiguang had no choice but to remind Emperor Changxing openly or secretly on some informal occasions.
At first, Emperor Changxing sent imperial envoys to investigate openly and covertly, but the results were always understated, and in the end nothing happened.
