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

Even Shen Zheng herself didn't notice that her breathing gradually calmed down while she was talking to Liang Fu.

Liang Fu's eyes flashed with approval, "Sir Shen, the most important thing in the furnace room is to control your breathing and control your body to adapt to the heat. Our furnace room is very simple and there is almost no way to cool it down. I said you were doing well before, and it was true."

His original intention was to encourage Shen Zheng and tell her that the trick was to "control your breathing."

But how could Shen Zheng, a rookie who had just entered the furnace room, control it deliberately?

It would have been better if he hadn't said it. After he started talking about it, Shen Zheng's breathing, which had just been controlled, became disordered again, and she even started breathing through her mouth.

"......" Liang Fu had good intentions but ended up doing something bad. A trace of regret flashed across his face. He racked his brains and changed the subject: "What do you think we should eat tonight?"

......

Two quarters of an hour later.

Liang Fu used a charcoal clip to cover the furnace mouth and looked at Shen Zheng: "The furnace is about to burn through."

Shen Zheng's face was covered with a wet rag, and a ray of nervous light flashed across her eyes, "It's time to play white sand."

Covering with a wet cloth was the way she thought of to adapt. It would take some time for the wet cloth to be dried by high temperature, and the time required for this process was also the time it took for her breathing to gradually stabilize.

In this way, the error she felt in breathing would be much smaller than if she went directly into the furnace room.

Liang Fu used a tool to open the middle material opening. Shen Zheng picked up a small portion of white sand that had been prepared long ago and stood on the small ladder. After the two looked at each other, the mouth of the basin tilted, and the white sand poured out, flashed through the slide of the material opening, and quickly slid into the furnace.

After Shen Zheng came down, Liang Fu used tools to close the feed opening again, "The next step is to wait."

When the white sand is calcined until it turns red inside and out, you can add feldspar and fluorite.

Even Shen Zheng couldn't tell exactly how long this stage would take. After all, the method of calcining glass with charcoal was too old. The quality of the charcoal and the structure of the blast furnace would affect the calcination time. No one could give an exact time without trying.

In addition, due to limited conditions, it is impossible to equip the blast furnace with a visualization window, so every subsequent furnace opening inspection is crucial for Shen Zheng and the others.

In the early stage of firing white sand, the furnace mouth must not be opened for inspection. Once cold air enters the furnace, the white sand will be heated unevenly, and the furnace charge will be ruined.

Therefore, the two of them had to estimate the time based on experience and guesswork, and they could only open the furnace mouth after the white sand was calcined red.

——Be on the safe side, but not too safe.

Every piece of charcoal burning under the stove at this moment is worth pure silver. It would be hard not to feel sorry for using too much.

As soon as she left the blast furnace room, Shen Zheng felt like she was reborn. Even the white air smelled sweet to her.

She drank two large bowls of water and just as she washed her face at the well, she heard Yu Nanshu's exclamation: "Sister Shen, what's wrong with you?"

Shen Zheng looked up in confusion, and Yu Nanshu came running towards her quickly, holding a food box in one hand and a dress in the other, her eyes full of worry.

"Why are you wearing summer clothes? It's so cold outside, you should put on your winter clothes quickly!" As she said this, she looked up.

Drops of water slid down the corners of Shen Zheng's jaw. Yu Nanshu was stunned. Then she saw her wet hair and asked in disbelief, "Did you wash your hair here?"

"Wash your hair?" Shen Zheng subconsciously touched her hair, her hand was sticky. She smiled and said, "I'm not washing my hair, I'm sweating. I was in the blast furnace room with Lord Liang just now. It's a bit hot in there. It's okay, Nanshu, we can stay over there and it won't be cold."

Yu Nanshu looked at her with a hint of discomfort in her eyes, and followed her to the outside of the blast furnace room without saying a word.

A wave of hot air blew towards her, making Yu Nanshu feel warm all over.

"I didn't lie to you, did I? It's warm here, and you won't catch a cold even if you wear summer clothes." Shen Zheng asked her with a smile, "Didn't I tell you not to come? Why are you here again? This trip will delay a lot of things. You have to finish the homework assigned by the teacher after school, and you also have to design clothes for the cloth shop..."

Judging from the time, the county school had just finished classes. If Yu Nanshu had not run back to the county government office to get a lunch box, she must have skipped classes early.

Yu Nanshu listened to her chattering quietly, and spoke after a while, her voice muffled: "If I hadn't come, what would you and Grandpa Liang eat?"

"You." Shen Zheng stretched out her finger and tapped her forehead. "How can we starve in Tongan County? There are so many stalls near the county school. We can eat whatever we want."

It’s just not as delicious as the food cooked by Uncle Lai.

"This is different..." Yu Nanshu put the food box on the small table, opened the lid, and took out the food layer by layer: "I brought all the dishes you like. You and Grandpa Liang are so tired here, if you still can't eat well..."

Putting herself in their shoes, Yu Nanshu felt as if the sky was falling.

To be honest, she felt like crying when she saw Sister Shen's expression just now.

She knew that this was what Sister Shen was willing to do. Perhaps to be a good official, a powerful official, and a beloved official, one had to go through this. But for some reason, she had been particularly sentimental recently and wanted to "meddle in other people's business"...

Liang Fu had just walked out of the blast furnace room when he heard this and raised his eyebrows: "Xiao Nanshu, you said Grandpa Liang is also tired, then why are the dishes you brought all the ones that Lord Shen likes to eat?"

Yu Nanshu said subconsciously: "You...are not picky about food."

Liang Fu was stunned for a moment, then laughed again: "Then let Grandpa Liang see what delicious food Nan Shu brought today?"

Yu Nanshu not only brought food for Shen Zheng and the other two, but also brought her own portion, insisting on staying to eat with them.

Shen Zheng couldn't persuade her to leave, so she could only keep picking food for her. Seeing this, Yu Nanshu also kept picking food for her. Liang Fu raised his chopsticks, looked at the white rice bubbling in his hand, and smiled helplessly.

Well, the old man can take care of himself.

Before the sunset, Fang Ziyan and Pei Zhaoqi hurried to the printing house. When they saw Yu Nanshu sitting with Shen Zheng, they breathed a sigh of relief.

Before Yu Nanshu left with them carrying the lunch box, Shen Zheng once again asked her not to come and deliver food tomorrow, but she didn't know if she listened to him.

After a while, the workers also left together, and only Shen Zheng and Liang Fu were left in the huge printing house.

The sun had completely disappeared, and the night insects were finally able to start moving. At this time, an hour had passed since the white sand was put into the furnace.

Shen Zheng narrowed her eyes at the white smoke coming out of the furnace, and said to Liang Fu, "Master Liang, let's open the furnace and take a look in a moment."

Liang Fu hesitated for a moment, unsure: "More than an hour, is it really enough?"

In the past, when I was in the Ministry of Works, let alone burning for an hour, even if I burned it for a whole night, the white sand could only be burned to become sticky, but it could not be burned like what Shen Zheng said - completely red.

Although he believed in Shen Zheng, he was still worried that they wouldn't be able to get the timing right.
