Daqin: Signing in at the beginning is ten times the combat power of Lu Bu

Chapter 409 Spring, Damping Carriage

"Have you heard that Mrs. Xiao also gave birth to a lovely little princess for His Royal Highness, mother and daughter are safe!"

"It just so happens that today is the Mid-Autumn Festival. Isn't this double happiness and double joy!"

"Yes, a little princess made His Royal Highness add a Mid-Autumn Festival. If there is another princess, will there be more festivals?"

"Seems like a good idea!"

"Look, the Mid-Autumn Festival special issue of "Daqin Daily" also published a piece of good news."

"That is the Engineering Academy under His Royal Highness. It has developed the technology of using fresh milk to make milk powder, and specially added other nutrients, which is very suitable for newborn infants."

"As long as they are newborns under one year old, regardless of gender, after the New Year, they can go to the Maternal and Child Health Department to apply for a free can of one catty milk powder, and all subsequent milk powder will be sold at half price!"

"This is great. My family has been short of milk, and the baby can't be fed, and I can't buy fresh cow and goat milk. I'm worried!"

"It's a good thing you didn't. As I said here, it's best not to give fresh milk to infants and young children. The digestion and absorption ability of infants and young children is too poor, so milk powder is more suitable."

"It's because the conditions are good now. Before changing to it, let alone children, adults can't eat such things by themselves, let alone pick and choose!"

"So, today's children are really happy to catch up with such a good time."

"We're not bad, okay? It's not like every household is eating sweet mooncakes now!"

"Hahaha, all of this is thanks to His Royal Highness for bringing us a good day!"

Amidst the hearty laughter, the people of Daqin celebrated this new reunion festival with joy.

In the imperial palace, there were also lights and festoons, and it was a festive scene.

Ying Yu brought three real wives, Wang Ying, Xiao Mei and Di Ya, as well as two cute little princesses, as well as various gifts, to celebrate the festival with Ying Zheng.

"Mid-Autumn Festival, you kid didn't come here empty-handed, did you?"

After seeing Ying Yu and his family, Ying Zheng laughed and made a joke.

Looking at the big and small bags in Ying Yu's hands, Ying Zheng was also looking forward to it.

As parents, the happiest time is undoubtedly the reunion of the family during the festival and the filial piety of the children.

"My son brought a lot of gifts to my father, my father, would you like to guess?"

Ying Yu smiled slightly.

"You really can't get rid of your habit of playing tricks!"

Ying Zheng shook his head with a smile and said, "One of them should be the card that you and your father talked about last time, Doudizhu, right?"

"Father guessed right, but this playing card is just an appetizer in the gift!"

Ying Yu chuckled.

"Appetizers? Then I can look forward to the main course you brought."

"What is this car for?"

Ying Zheng looked around, then suddenly looked at a small car with four wheels, and asked curiously.

"Father, this is Xin'er's stroller. When Wan'er grows up, there will be one too!"

Ying Yu laughed and said, "However, the other present I prepared for my father has something to do with the car!"

"Oh?"

Ying Zheng suddenly became more curious.

After Ying Yu demonstrated the purpose of the stroller, Ying Zheng quickly understood it.

But Ying Zheng couldn't figure it out if he wanted to connect with himself.

This box doesn't look very big, and it doesn't look like it contains a carriage or something.

After pondering for a moment, Ying Zheng still looked at Ying Yu.

"In it, there is a new work just researched by the Academy of Engineering, called Spring."

Ying Yu took out a spiral-shaped soft steel ring from the box, and introduced:

"The principle of this spring is similar to that of a bow and crossbow. After being deformed by force, there will be a force to return to its original shape."

"This power, on the bow and crossbow, can make the bow and arrow fly faster and farther, and when applied to the frame, it can buffer the torsion when the vehicle is running through the deformation of the spring, so that the vehicle can run more smoothly."

"Erchen has asked the Academy of Engineering to build a carriage with a new type of spring suspension and shock absorption specially for the father, and it has parked in Miyagi."

"The heavy-duty carriage dedicated to freight transportation is also being finalized."

Ying Yu smiled slightly.

"Spring? Shock-absorbing carriage?"

Although he didn't know the reason, Ying Zheng nodded in satisfaction.

Emperor Shihuang, who had made several tours, was well aware of the hardships of boats and vehicles. The reason why he used water as much as possible during his last east tour was not only faster, but also less bumpy.

After all, most of the accompanying officials were not young enough to withstand the bumps of the long-distance carriage.

Now, if the spring shock absorber that Ying Yu mentioned can really work, it will definitely be a magic weapon for Daqin's logistics and transportation.

And the logistics is convenient, whether it is commercial or military, it has a great effect.

Moreover, Ying Zheng can travel by himself much more comfortably.

This made Ying Zheng very satisfied.

"However, if such a good thing is applied on a large scale, it is difficult to guarantee that it will not be leaked. Will it be learned by other countries?"

Ying Zheng played with the spring in his hand repeatedly for a long time, hesitated for a moment and said.

"Father, there is no need to worry too much. Although the structure of this spring seems simple, it is not easy to manufacture it."

"First of all, this requires extremely high toughness for mild steel, even if it is slightly unqualified, it cannot withstand repeated deformation and impact."

"And it is not a simple matter to stamp mild steel into such a shape."

"Without mature technology and suitable machinery, if you want to manufacture springs by hand, one or two is fine. Large-scale is absolutely impossible, and the cost will be frighteningly high."

Ying Yu had a confident expression on his face.

Although springs are so cheap that many people almost ignore them in later generations, it is not an easy task to manufacture them in Daqin.

You know, in the history of later generations, the relevant theories and large-scale applications of springs came after the 17th century, nearly 2000 years away from Daqin.

Especially now, apart from Great Qin, other countries, even regional powers such as Rome and Carthage, do not have a well-formed scientific research concept, not even a decent laboratory, even if they get one or two finished springs, The steel formula and process cannot be analyzed.

Manual steelmaking, try one kind, enough to try until the end of time.

To put it bluntly, with Ying Yu's efforts, Daqin, which has already begun to transition from an agricultural society to an industrial society, has completely crushed other countries in terms of productivity.

And this gap is still widening.

"So, I'm relieved!"

Ying Zheng's face was full of pride.

It turns out that Daqin has become so powerful!

This is the best gift Ying Zheng has ever received!
