Transmigrated into a female county magistrate during a famine, leading her country to prosperity

Shen Zheng began to circle and dot on the paper.

If you don't know the quality of the raw materials, you must first choose the ones that are close to the place of origin. After all, sand and gravel are heavy, and if you need raw materials in large quantities in the future, the transportation cost must also be included.

She circled two prefectures outside Liuyang Prefecture and wondered whether to send someone to look for them or go the fifth route.

Liang Fu became more and more curious about Shen Zheng, especially when there were countless nouns written on the paper in front of Shen Zheng that he didn't recognize.

They are clearly words, why can't I recognize them when they are put together?

And the raw materials she was looking for were mostly common items in the Great Zhou, especially white sand.

White sand...

Liang Fu pursed his lips, hesitated for a moment, and then chose to ask tentatively: "Sir Shen, I don't want to find out what you want to do, but this white sand..."

He paused, "Do you want to use it to calcine like dolomite?"

Shen Zheng put down the brush and nodded: "That's right. I want to try to make something, and white sand is the main raw material."

"But..." Liang Fu was a little confused, frowned and asked her: "I wonder if Lord Shen knows that white sand...cannot be boiled."

All minerals in the world are gifts from heaven and earth. Liang Fu would be more willing than anyone else to use them if they could benefit mankind.

Unlike dolomite, which looks "very ordinary and difficult to attract attention", the beautiful appearance of white sand has long attracted the attention of the Ministry of Industry - how to use sand and gravel? How to benefit the people? They don't know, in short, just one word, "burn it" first.

But when it was burned, there was a problem - this thing would not melt at all! It would be the same when it was put in, and it would be the same when it was taken out. At most, it would form a lump, and it would fall apart again after a few hammers.

The Ministry of Industry also struggled and doubted the craftsmanship of the calcining masters, but after many attempts, they finally came to a conclusion about white sand - it is beautiful, flashy and useless!

But even such a "useless thing" has been specifically requested by Lord Shen!

This had to attract Liang Fu's attention.

Lord Shen...I'm afraid he won't do useless work? The reason why he tried this way was actually to know how to burn this white sand.

"Can't be boiled?" Shen Zheng was stunned for a moment, then reacted: "You mean this thing is difficult to melt and refine?"

In her words, the melting point is high. For example, in the earthen kilns that burn limestone in the county today, even if you add more firewood to the fire, the temperature in the kiln is difficult to reach the melting point of quartz sand.

"That's exactly what I mean." Liang Fu looked at her inquiringly, "Does Lord Shen really know?"

"Hmm..." Shen Zheng nodded and told the truth: "I know."

"Then..." Liang Fu became a little excited: "Could it be that Lord Shen has a way to melt the white sand?"

There is a way to melt it, which is equivalent to the use of white sand!

White sand is useful, which means the Ministry of Industry has new work to do!

Facing Liang Fu's excited, curious, yet cautious gaze, Shen Zheng suddenly felt a little sorry for him.

Liang Fulai has been in Tongan County for several months. He is either working or on his way to work. The knowledge I have learned is obviously what he most wants to explore and what he dreams of, but I rarely mention it to him.

Shen Zheng was silent for a moment, and then said to him seriously: "Master Liang, thank you for your hard work during this period of time."

"what?"

Liang Fu was a little confused. Aren't they talking about Baisha? Why did Lord Shen suddenly start to feed him "magic potion"?

That's right.

Shen Zheng's "flattery" and "consolation" to others were seen by many people in the county government as just a lie.

——She would use countless nice words to bluff people until they were at a loss, and then coax them into willingly doing things for the county. For example, Yu Shizhang and Shen Xingjian, they were often in her way.

Liang Fu couldn't help but perk up, and quickly shook his head and said, "What I did was all within my duty. Lord Shen's words are really embarrassing for me."

The defensiveness on his face was obvious. Shen Zheng's mouth twitched slightly when she saw it, but the guilt in her heart faded a lot.

She said directly: "Sir Liang, if you have any questions before or in the future, you can ask me directly, and I will tell you everything I know."

This big cake came too suddenly, and Liang Fu obviously couldn't digest it: "Lord Shen, what do you mean...?"

"You can ask me anything." Shen Zheng replied immediately: "You and the Ministry of Industry can ask me about any difficulties or things that are difficult to understand. If I can help you or the Ministry of Industry, I will do my best. But I can't guarantee that I know everything."

Shen Zheng was also afraid that she had raised her foundation and would not be able to answer questions in the future, which would disappoint Liang Fu.

But Liang Fu is so happy now - there is such a good thing!

In fact, he had long forgotten the original purpose of his coming to Tongan County.

It seemed that he just wanted to see the textile machine and see who could have built it.

Later on, I felt that there were always new things in Tongan County, so I decided to stay for a while and see how Lord Shen would act in the future.

Later on, I felt that I was getting old, and Tongan County was actually a very suitable place for retirement, so I decided to explore and enjoy my retirement at the same time.

"Sir Shen, you..." Liang Fu laughed so hard that his face wrinkled into a ball, but he still politely declined a few words: "I feel a little embarrassed when you say that..."

But he really had a lot of questions in his mind that he wanted to ask Shen Zheng!

All those things that had been piling up for a long time and had no answers were now stirring in his throat, and he was afraid that if he opened his mouth, he would be unable to stop them from pouring out.

"Please don't talk about this with me." Shen Zheng smiled helplessly, "Let's talk about Baisha first, shall we?"

Liang Fu nodded vigorously, "Okay, okay, let's talk about Baisha, Baisha is good."

As long as it is something he doesn't understand, he can say anything!

"The melting point of white sand... The melting point is the temperature required for white sand to change its external form and become a flowable, slurry-like form."

Liang Fu took out the booklet again without knowing when, and said with the look of a model student: "Master Shen, please continue."

"…white sand has a very high melting point, much higher than the temperature required to calcine limestone, and even higher than iron."

"Higher than iron?!" Liang Fu was only shocked for a moment before accepting the fact. "Yes, yes, if it's not higher than iron, how could it not be moved at all by high temperature firing?"

Even iron would turn red and soften at that temperature. Although it still could not be melted into molten iron, it was enough for forging. However, the white sand did not move at all, which showed how high its "melting point" was.

Liang Fu thought a lot in an instant. He pressed the table excitedly, his face flushed, his neck swollen, and his breathing rapid as he asked: "If this method can melt white sand, can't it also melt iron ore?!"
