Jiang Wei led people to set up defenses outside to capture the fleeing Japanese pirates.
Xu Miaojin has been staring at Chang Mao.
Of course, Jin Yiwei's troops did not relax either.
The little girl shook her head and said: "Since Huang Zicheng and Qi Tai were executed, Chang Mao has been closed at home and has not seen guests."
"The people from Jinyiwei have been watching around Chang Mansion, but they haven't found anything."
"I was worried, so I bought a group of beggars with money and kept an eye on everyone who came in and out of Chang Mansion, but I still found nothing."
Zhu Yunzhen frowned slightly.
Logically speaking, this shouldn't be the case.
Qi Tai was killed. Although he did not simply confess that he had colluded with the Japanese pirates, and Qi Tai was not clearly implicated, he should be worried about whether Qi Tai had betrayed him.
He couldn't stand still.
Xu Miaojin said: "I do have a suggestion. Get rid of all the Jinyi guards who are keeping an eye on Chang Mansion."
"Chang Mao won't do anything as long as they are here."
"I will be responsible for keeping an eye on Chang Mao. I will ensure that nothing goes wrong."
Zhu Yunzhen looked up at her and asked solemnly: "Are you sure?"
The little girl smiled sweetly and said, "Yes. I am good at staring at people."
"good!"
Zhu Yunzhen agreed immediately.
Xu Miaojin is still very reliable in her work.
Basically nothing can go wrong.
"I came here today to do one more thing." Xu Miaojin did not leave, but continued: "The cement you asked the craftsmen to develop has been produced."
"Seriously?" Zhu Yunzhen was overjoyed.
"Yes!" Xu Miaojin nodded and said with a smile: "I brought it, you come and take a look."
Zhu Yunzhen followed him out immediately.
Yao Guangxiao was very curious.
He left early that day and did not see Zhu Yunxuan's proposal for the craftsmen to develop cement.
This was the first time he heard the name cement.
So, he followed closely and followed him out.
"It's made of cement, sand and stone."
Xu Miaojin pointed to a piece of road and said.
Yao Guangxiao walked over and looked at it carefully.
The findings are very similar to rocks, but a little different.
Moreover, it is a whole.
Xu Miaojin asked someone to bring a hammer and hit it hard, making a banging sound, but there was no sign of cracking.
Yao Guangxiao's pupils suddenly dilated.
He has seen a lot, but he has never seen anything like this in his life.
“How is this made?”
"His Royal Highness Taisun invented cement." Xu Miaojin glanced at Zhu Yunzhen again, full of admiration.
She took a bag of cement and said, "This is what you mix with sand and pebbles. After it dries, it forms a hardened ground like this."
Yao Guangxiao stretched out his hand and grabbed a handful of cement. It was as thin as dust and there was nothing magical about it.
I never imagined that this thing could be so miraculous.
The point is, he has never seen this kind of thing.
Invented by His Highness Taisun?
A creation of the void?
He turned to look at Zhu Yunzhen, his pupils full of horror.
"Okay, okay, I didn't expect it to be done so quickly."
Zhu Yunxuan looked at the concrete floor and then at the cement, and he was also overjoyed.
After all, he didn't know the specific formula or method at all, he only knew a general direction.
If he had been left to research it himself, Zhu Yunxuan estimated that he would never be able to develop cement within three to five years.
Unexpectedly, those craftsmen were able to produce cement in such a short period of time.
really.
There are geniuses everywhere in the world.
But when I think about it, it feels normal.
There is a certain order of learning and there is a specialization in the art.
The craftsmen have been doing this for a long time and have a lot of hands-on experience.
Secondly, he explained it as his grandson and gave him enough funds, so the craftsmen would naturally do a lot of experiments.
There is strength in numbers.
Everyone uses different methods to conduct various experiments.
It was no surprise that it was developed quickly.
“When you pour cement into concrete, you have to pay attention to the proportion of sand and stone.”
"This affects the performance of the concrete."
"Let them experiment a few more times before finalizing it."
Zhu Yunzhen did not say what the specific ratio was.
Although he knew it very well.
But Zhu Yunxuan also saw that the cement particles made by craftsmen were somewhat different from the cement produced industrially in later generations.
There is no way, the industrial level is restricting it.
You can't force this, you can only wait for time to accumulate and make progress slowly.
The cement was different, and the proportion of sand and gravel, of course he didn't dare to talk nonsense.
"Well, the craftsmen are already experimenting, and this piece of concrete is the best that has come out of the experiment."
Xu Miaojin smiled and said: "I know what you mean, which is to constantly experiment and try various methods."
In fact, it can also provide theoretical guidance.
Zhu Yunxuan added something while he was talking.
Did not say.
His theoretical knowledge was very limited.
Moreover, science at this stage does not require overly complex and difficult theories.
He is also ready to promote this aspect.
Yao Guangxiao was stunned beside him, realizing more and more that he still didn't understand his grandson.
Being able to write poetry, fight, know how to manage the court, and be able to balance the civil and military forces, that's all.
But how did he come up with guns, cannons, mimeograph machines, cement, these things?
Yao Guangxiao suddenly felt so stupid.
Really stupid!
He couldn't think of something like cement even if he tried to think about it.
But Zhu Yunxuan looked extremely calm, as if the invention of cement was insignificant to him and not worth mentioning at all.
At this moment, Yao Guangxiao suddenly felt a little suspicious.
Could it be that the other party was really the reincarnation of Emperor Zhenwu?
Otherwise, this matter is really unexplainable.
He glanced at Zhu Yunzhen with confused eyes.
"Pour concrete with cement, and replace all the dirt roads in the city with cement paving."
Zhu Yunzhen decided immediately.
"Also, lay a cement avenue from Jinling City to the Magic City New City."
no doubt.
Magic City New City will become the economic center of Ming Dynasty in the future.
If you want to build a road, the first choice is to go directly from the capital to the magic city.
Daming's current steel production is far from enough.
Without enough steel, it is possible to build houses with cement, but it is obviously not the optimal solution.
He temporarily thought of two uses.
One is to build flood control embankments.
Adding cement can improve the quality of the embankment to a higher level.
On the other hand, it’s all about paving the roads.
Transportation is fundamental to a country's commercial development.
However, the cost of stone roads is too high.
Even within Jinling City, there are many places where there are still stone roads.
Besides, there are many problems with the stone road.
At least it's not very flat.
Zhu Yunxuan had a deep understanding of this when he was riding in a carriage.
It's so bumpy.
He thought for a while and then said: "In addition, pave a flat road with cement from Jinling to Yangshan."
Lao Zhu is still there, still the emperor of the Ming Dynasty.
It is very important to have his support in everything.
Anyway, the road leading to Yangshan can also connect to other places in the future.
Not a waste.
Lay it down now so that Lao Zhu won't have to go too bumpy when he returns to Jinling Palace from Yangshan or goes out of the city.
For an old man, this is important.
Only when Lao Zhu experiences the benefits of cement roads will he fully support it.
"Yeah!" Xu Miaojin nodded, but there was a strange look on his face.
After hesitating for a while, she said: "There is no problem in paving the road, but the Technology Research and Manufacturing Bureau has no money."
