In October of the tenth year of Jianxing, Guandong still had a hint of warmth, while Hanzhong was already a hint of coolness.

Ding Niuwa lowered his head and carefully walked along the cobbled path following the small yellow gate in the palace.

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

This was what Ding Niuwa personally led the shop when the queen was pregnant two years ago.

It is said that the queen can walk on it every day, which can activate the bloodline.

Following the cobbled path to a palace, the little yellow gate asked Ding Niuwa to wait outside and report it himself.

After a while, the news quickly came out to let Ding Niuwa go in.

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

"I have seen Your Majesty, I wish you a long life and a long life!"

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

"Thank you, Your Majesty."

Over the years, from Yueqi to Jincheng, and from Jincheng to Hanzhong, there were many new water mills built in places where there was water flow, so that the people could grind the flour and pound rice.

Most of these new water mills were built by Ding Niuwa, so they were recommended as Sima, a subordinate of the Diannong Duwei for their merits.

Ding Niuwa also participated in the palace in front of him, and he was also one of the foremans.

Because of his outstanding performance, he entered Hanzhong Metallurgical again and stayed in Hanzhong since then.

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

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

His brother-in-law is Feng Mingwen's eldest disciple.

So Ding Niuwa has benefited from it and is regarded by the royal family as one of the characters who can strengthen their relationship with Feng Mingwen.

It is precisely because of this relationship and his current identity that as long as Nanxiang or Feng Mingwen makes any new things, the Royal Family can get them as soon as possible.

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 is made of cement, it is as strong as a rock - of course, it is not the kind of cement that Feng Yong first made.

It is calcined cement that was only produced in Nanxiang in recent years.

Limestone is used as the main raw material, and a certain proportion of other auxiliary materials are added, and then placed in a high-temperature kiln to calcinate.

The cement produced by this process is the real building cement, and Feng Yong still has this knowledge of high school chemistry.

But at the beginning, he didn't have that much money, no one, no one, not so much time, and the conditions for calcination were not mature.

Therefore, we can only make raw cement, with a large amount of raw materials and full pipes, and use them to pave the road.

However, there is a but.

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

This knowledge point is worth a thousand gold.

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

After all, the great man has two national senior engineers, Huang Yueying and Pu Yuan.

Another governor Feng gave the Nanxiang team the right direction and did not have to take detours.

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

The possible meaning of this is that there is a kiln but no kiln, and the yield rate is relatively low and the pass rate is even lower.

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

But things in this world are usually more expensive than things.

The newly built side hall in Hanzhong Palace the year before yesterday was constructed by the Nanxiang Engineering Team using new cement.

The entire palace is integrated, not afraid of water and fire, and is as strong as stone, making the emperor and the queen and other local buns amazing.

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

Nowadays, most of the materials of wealthy families are made of wood.

It looks good, it is beautiful and beautiful.

But it's so strong when it burns.

As long as a room is burning, you must prepare to burn all the rooms.

Moreover, everyone now has to burn coal and charcoal to keep warm in winter, and the hidden dangers of water flow are infinitely increasing.

Not to mention that over time, the collapse caused by the rainwater is disrepair, termite chewing, and other factors.

Just like in the past few years in the north, Cao Pi led his troops to the east, and Queen Guo stayed at Yongshitai, Xuchang.

It rained heavily at that time, and the city towers collapsed and damaged. For the sake of safety, the relevant officials had to ask Queen Guo to move to another place.

This is still the case with the imperial palace, which shows the vulnerability of buildings in this era.

Not to mention that these days, wars are frequent and thieves are everywhere, and even villages are focused on solidity.

Therefore, this kind of house that is both sturdy and convenient for construction, has no hidden dangers, and is not inferior to a house made of wood, which is perfect in the eyes of the local bully of the Three Kingdoms era.

As soon as the new cement came out, it was spoken by the royal emperor and descendants and was suddenly famous in Shu.

In the Han Dynasty, everyone knew that Nanxiang had a new type of artificial stone called cement.

As long as you mix water and stir it into mud, it will become as hard as a stone after it is dried. This is something God gave to the Han Dynasty.

The only pity is that even if you have money, you have no place to buy such rare things, and only offer them to the royal family and the powerful.

Because of burning cement, the black smoke in Nanxiang is rolling in the sky.

Therefore, some people in the world are circulating that this is an evil ghost thing that King Feng was dug out from the underground.

The governor of Liangzhou thousands of miles away said that you illiterate people know what you are!

Then Ding Niuwa gave a thumbs up.

The prime minister of the Han Dynasty sighed to the sky, saying that this thing is rare, what a pity!

The emperor and empress who were holding her son in the Panshi Palace said that even if it was an evil ghost, I like it.

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

"Can you make this thing?"

Ding Niuwa held the paper in his hand. At first glance, he knew that it must be the work of governor Feng.

Or it must be related to Governor Feng.

Scale bars, data, units, perspective views, parts and installation steps are the most obvious and simple.

Back then, he followed Feng Feng to work in a water mill room. When he watched Feng Feng draw the drawings by himself, he felt that it was simply a magical skill.

The craftsman who could not read a word of knowledge could slowly figure it out even if he didn't understand what was written on it.

Based on his experience over the years and his trust in governor Feng, Ding Niuwa did not delay much and responded in one go:

"Report to your Majesty, you can."

"Okay, if you need something, just speak. I will continue to ask the people in the inner palace to find a way."

The emperor above said very happy, "This thing was made for the prince. The material can be used as good as it can, and you don't have to worry about money and food."

Rich and willful.

Anyway, I use the money from the inner government, not the money from the treasury, so my father couldn't control it.

Although the reconstruction of the Northern and Southern Army almost emptied the inner palace, it could not resist the queen having a good brother-in-law, right?

Ding Niuwa quickly responded, and then, under the leadership of Xiaohuangmen, left the palace.

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

"Why haven't the coking coal from Nanxiang arrived yet?"

Ding Niuwa scratched his head:

"Dandel, isn't this the day yet?"

"Don't this burn quickly?" Pu Yuan said "tsk", with a look of helplessness on his face, "The army must be urgent, the Prime Minister's Mansion must also be needed in the palace."

"You don't know that the Prime Minister came here in person a few days ago."

Pu Yuan, who has traveled all over the Sichuan Mountains in Shu, just to cast high-quality weapons, has finally found his life goal over the years.

After personally forging swords that are comparable to hundreds of refining swords, Master Pu felt that he had reached the peak of his life.

In addition, Nanzheng is originally the largest iron ore in Hanzhong, and there is a brand new forging method. How can you be worthy of your life if you don’t work hard?

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