In October of the 10th year of Jianxing, Guandong still has a hint of warmth, while Hanzhong already has a hint of coolness.

Ding Niuwa lowered her head and carefully followed the small yellow gate of the palace on the cobblestone path.

The base of the cobblestone path is paved with cement, with half of the cobblestones embedded in the cement and half exposed.

This was built by Ding Niuwa himself when the queen was pregnant two years ago.

It is said that letting the queen walk on it every day can rejuvenate the blood vessels.

Walking along the cobblestone path to a palace, the small yellow gate asked Ding Niuwa to wait outside, and he went in first to report.

After a while, a special announcement was sent out to let Ding Niuwa in.

Ding Niuwa quickly took off her shoes, straightened her clothes, and then trotted in. After entering, she didn't dare to raise her head and shouted:

"I have met Your Majesty. May Your Majesty live long and live happily ever after!"

The voice from above came from far away, with a faint echo: "Get up."

"Thank you, Your Majesty."

Over the years, from Yuexun to Jincheng, and then from Jincheng to Hanzhong, new-style water mills were built wherever there was water for the people to grind flour and pound rice.

Most of these new water mills were built by Ding Niuwa, so he was recommended as a subordinate of the Diannong Duwei because of his merit.

Ding Niuwa was also involved in the palace in front of her and was one of the foremen.

Because of his outstanding performance, he joined Hanzhong Ye again and has stayed in Hanzhong ever since.

He came from Fengzhuang and received personal guidance from Feng Mingwen.

The most important thing is that his sister Yaomei is now one of the managers of Nanxiang.

His brother-in-law is Feng Mingwen’s first disciple.

Therefore, Ding Niuwa was regarded as one of the people who could strengthen the relationship with Feng Mingwen by the royal family.

It is precisely because of this relationship and his current status that whenever Nanxiang or Feng Mingwen comes up with something new, the royal family can get it immediately.

Take the palace in front of you as an example.

This palace is called Panshi Palace.

The name is a bit weird, but very vivid.

Because the whole thing is made of cement, it is as solid as a rock—of course, not the kind of cement Feng Yong first made.

It is calcined cement that was developed in Nanxiang in recent years.

Limestone is used as the main raw material, mixed with a certain proportion of other auxiliary materials, and then put into a high-temperature kiln for calcination.

The cement produced through this process is the real construction cement, and Feng Yong still has this high school chemistry knowledge.

It’s just that at the beginning, he didn’t have that much money, not that many people, not that much time, and the conditions for calcining were not mature.

So we can only make raw cement, use it in large quantities to fill the pipes, and use it to pave roads.

However, there is a but.

Although Governor Feng couldn't figure it out, he knew the process.

This knowledge is worth thousands of dollars.

Because of the development of Dahan over the years, basic things such as blowers, hydraulic forging, coking coal, etc. have been improved a lot.

After all, Dahan has two national-level senior engineers, Huang Yueying and Pu Yuan.

And Governor Feng pointed the Nanxiang team in the right direction without making any detours.

Therefore, the continuous increase in available temperatures has made it possible to calcined cement.

What this may mean is that if there is only one kiln but no kiln, the finished product rate is relatively low and the pass rate is even lower.

Anyway, there is no way to apply it on a large scale.

It's just that the rarer things in this world are, the more expensive they are.

The newly built side hall of the Hanzhong Palace the year before last was constructed by the Nanxiang engineering team using new cement.

The whole palace is integrated, not afraid of water and fire, and is as solid as stone, which amazed the emperor, queen and other country bumpkins.

Even the Prime Minister of the Han Dynasty came to inspect it carefully several times.

These days, most of the houses of wealthy people are made of wood.

Good-looking means good-looking, beautiful means beautiful.

But when it burns, it's called a boom.

As long as one room is on fire, be prepared for all rooms to be burned down.

Moreover, now that everyone has to burn coal and charcoal for heating in winter, the hidden danger of water leakage is even greater.

Not to mention that over time, rain water soaked it, it fell into disrepair, termites gnawed it, and other factors that caused it to collapse.

Just like a few years ago in the north, when Cao Pi led his army to the east, Queen Guo stayed at Yongshitai in Xuchang.

At that time, it rained continuously and many of the city towers collapsed and damaged. For the sake of safety, the relevant officials had to petition Queen Guo to move to another place.

The palace is still like this, which shows the fragility of buildings in this era.

Not to mention that these days, wars are frequent, thieves are everywhere, and even villages are built to be strong.

Therefore, this kind of house is sturdy, easy to build, has no hidden dangers, and is no less decorated than a house made of wood. In the eyes of the rustics of the Three Kingdoms era, it was perfect.

As soon as the new cement came out, it was endorsed by emperors and emperors, and its reputation spread throughout Shu.

Everyone in the Han Dynasty knows that a new type of artificial stone has been produced in Nanxiang, called cement.

Just mix it with water and stir it into mud. When it dries, it will be as hard as stone. It is a gift from God to the big man.

The only pity is that even if you have money, there is no place to buy such rare items. They are only for the royal family and the powerful.

Due to the burning of cement, more and more black smoke billowed into the sky in Nanxiang.

So some people in the world spread the word that it was an evil ghost thing that King Feng had people dig out from the ground.

Thousands of miles away, the governor of Liangzhou said that you illiterate people know nothing!

Then Ding Niuwa gave a like.

The Prime Minister of the Han Dynasty looked up to the sky and sighed, "This thing is rare, what a pity!"

The empress, who was amused while holding her son in the Panshi Palace, said, "Even if it's an evil thing, I like it."

At the same time, he took out a stack of paper, asked the waiter to pass it to Ding Niuwa, and asked:

"Can you make this?"

Ding Niuwa held the paper in his hand, and at a glance, he knew it must be the handiwork of Governor Feng.

In other words, it must be related to Feng Jishi.

The scale, data, units, perspective drawings, parts and installation steps are all drawn in the most clear and simple way.

Back then, he was working on the water mill behind Governor Feng. Watching Governor Feng draw the drawings with his own hands, he felt that it was a magical skill.

When an illiterate craftsman gets the manuscript of Governor Feng, even if he doesn't understand what is written on it, he can slowly figure it out.

Based on her experience over the years and her trust in Governor Feng, Ding Niuwa agreed without any further delay:

"Your Majesty, yes."

"Okay, if you need anything, just ask, and I will give the order and let the people in the inner palace come up with a solution."

The emperor above sounded very pleased, "This thing is made for the prince. Use the best materials you can. You don't have to worry about money and food."

Rich and willful.

Anyway, the money used is the money of the inner government, not the treasury, and the prime minister has no control over it.

Although the reconstruction of the Northern and Southern armies almost emptied the imperial palace, the queen still has a good brother-in-law, right?

Ding Niuwa quickly agreed and then left the palace under the leadership of Xiao Huangmen.

As soon as he returned to Hanzhongye, Pu Yuan found him:

“Why hasn’t the coking coal from Nanxiang arrived yet?”

Ding Niuwa scratched his head:

"Pandong, isn't the day yet?"

"Doesn't it burn quickly?" Pu Yuan said "tsk", with a look of helplessness on his face, "This weapon is urgently needed in the army, the prime minister's office, and the palace."

"It's not like you don't know that the Prime Minister came here in person a few days ago."

Pu Yuan, who traveled all over the mountains and rivers in central Sichuan, just to be able to forge superior weapons, finally found his life goal after all these years.

Master Pu felt that he had reached the pinnacle of his life by personally forging a sword that was comparable to a hundred-refined sword.

In addition, Nanzheng is the largest iron ore producing area in Hanzhong, and there are brand-new forging methods. How can you live your life without working hard?

"Hurry, pack up and go to Nanxiang to ask."
