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

The lime water was bubbling. Yu Shizhang asked her, "Why do you put leaves in it?"

Shen Zheng winked at him, "What will come out later is the leaf rack."

“Is it so powerful?!” Yu Shizhang opened his eyes wide, thinking how this was different from poisonous water!

He wanted to see the scene inside the bowl through the mouth, but the white fog was too thick and he could not see anything.

As everyone waited anxiously, time passed quietly. The lime water reacted completely, the white mist dissipated, the slaked lime slowly sank to the bottom, and the lime water became clearer.

"This water..."

Yu Shizhang looked at the water in the bowl and murmured, "Is it Uncle Ben's illusion? Why does Uncle Ben feel that the water is much clearer?"

"Master, you have good eyesight." Shen Zheng praised: "Slaked lime water is also corrosive, so it is best not to touch it directly with your hands. But it also has the effect of improving farmland, and pouring it into turbid water can also flocculate some impurities in the water to the bottom, so it can also be used to treat sewage."

At this moment, whether it was Yu Shizhang or the people present, it felt that in just half a day, they had seen all the new and strange things that they had never seen in the first half of their lives.

This is really amazing!

It's just a piece of not-so-rare stone, but it has so many uses after calcining!

Yu Shizhang stared at Shen Zheng's head intently, "I really want to see how your brain can be so useful!"

Shen Zheng quickly reached out and covered her head with her hands. "My Lord, just look outside. Please don't open my head and take a look."

Yu Shizhang was amused by her, "How dare I? Your head is fine, it's better than anything else. In the future, I will specially send two people to protect your head."

Shen Zheng also laughed and tapped his head, "It's not that precious."

After she finished speaking, she squatted down, used a spoon to stir the leaf in the bowl a few times and then scooped it out.

Just as she had said before, the bark on the surface of the leaves had been corroded away, leaving only a thin layer of transparent veins.

Shen Zheng tore off a piece of cloth, wrapped the leaf around the stem and lifted the leaf up for everyone to see.

The villagers were amazed: "Where is the flesh on the leaves? Just gone like that?"

"It was corroded by this bowl of water! Look at the bottom of the bowl, there's still some leaf flesh!"

"Oh my god! Fortunately, it's just leaves. If we put our hands in there, our skin would be burned!"

Everyone rubbed their hands when they heard this, it was really possible!

Their skin is much more fragile than leaves. Just thinking about that feeling makes one's whole body ache!

Fortunately, the adults showed it to them at the beginning, otherwise some young and naive people might have secretly made it for fun.

Shen Zheng saw that her goal had been achieved and handed the leaf to Yu Shizhang. Yu Shizhang held the leaf high above his head and looked closely at the veins of the leaf under the sunlight.

He sighed, "Those leaves that have been buried underground for a long time look like this when they are dug out. Only the frame is left. But the one in front of Benbo is much better looking than those. The veins are intact, and there is a layer of leaf veins as thin as a cicada's wing."

Liang Fu was so excited that he leaned forward and said, "My Lord, can you show me?"

Yu Shizhang hadn't seen enough and was reluctant to give the leaves away, which made Liang Fu so anxious that he stamped his feet on the spot.

Shen Zheng chuckled and whispered, "Master, show it to Lord Liang first. I didn't choose this leaf well just now. Go and pick a few leaves you like later. I'll make them into bookmarks for you to take back and use as bookmarks."

This proposal couldn't be better!

Yu Shizhang suddenly felt that the leaves in his hand were nothing, as they were not made specially for him!

He waved his hand and handed the leaf in his hand to Liang Fu, who took it eagerly and looked at it carefully.

The experiment of quicklime meeting water came to an end amid the exclamations of the crowd, and the next step was the highlight of the day - mixing mortar.

Shen Zheng first asked Niu Chu to add a little water to the stone mortar, mix the quicklime powder and mature lime, and then selected a piece of compacted mud and ordered people to pour loess and fine sand on the ground in proportion.

The last step is to add slaked lime and then use an instrument to mix the three ingredients evenly.

The sun gradually rose higher in the sky and it was already noon, but no one "left the table" to go home. They all stared at the mixed soil on the ground.

The villagers volunteered to help, but were all rejected by Niu Chu.

"It's just a little bit of soil. It's okay. Mix it up quickly."

A quarter of an hour later, the cement mortar that everyone had been waiting for was completed.

Because the cement mortar contains a lot of loess, lime and fine sand cannot compete with it for color, so the entire cement mortar appears to be a yellowish earth color with a little gray.

Shen Zheng chose a piece of mud under the shed and ordered people to level the soil, then surrounded the small piece of land with bamboo strips.

"Okay, let's use this piece of land as an experiment. Shovel some cement over here and pour it in."

The mortar was surrounded by bamboo strips. Shen Zheng took out the wooden hammer that he had prepared long ago and pounded the soil flat in just a few strokes.

Niu Chu hurried forward and tried to take the mallet, but was rejected by Shen Zheng: "Let me demonstrate it to you first. This soil needs to be pounded repeatedly and compacted. Someone needs to watch over it for the next two days. After one layer is pounded solid, the next layer can be laid and compacted. If you want to use it for a long time, it is best to lay three layers."

Wu Lizheng led everyone to gather around and said, "Everyone, watch what the master does. Since the master has chosen to pound the soil in our Xiahe Village, then we should help the master. Who will pound the soil in the next two days?"

As soon as these words were spoken, everyone raised their hands.

"Me, me, me! Wu Lizheng, choose me! I'm strong and I guarantee I'll hit you squarely!"

"What's the use of your great strength! This requires not only great strength, but also carefulness! Wu Lizheng, you know me! I'm not bragging, in our Xiahe Village, I am the most careful person!"

Just as everyone was vying to recommend themselves, the sound of horse hooves was heard not far away.

"My lord! My lord!"

Shen Zheng immediately recognized it as Xiao Yuan's voice.

She handed the gavel to Wu Lizheng and stood up.

Xiao Yuan was bouncing up and down on the horse, his face full of excitement and eagerness.

"Uu——"

Xiao Yuan stopped chasing the wind, because due to his quick movement, the wind left a trail of mud on the ground.

"What's the matter? Why are you so anxious?" Shen Zheng asked.

Xiao Yuan didn't have time to calm down, he swallowed his saliva and said: "The Canal Transport Bureau! Someone from the Canal Transport Bureau is coming!"

Shen Zheng immediately turned to look at Yu Shizhang and asked, "Who is coming?"

Xiao Yuan thought about it and said, "That gentleman said his last name was Wei!"

"Wei Que?" Yu Shizhang said to Shen Zheng, "It should be him, the deputy governor of the Grand Canal, who is in charge of the water transport in the Great Zhou. He is very loyal to His Majesty, and does not get along well with the governor of the Grand Canal."

Shen Zheng interpreted these words.

Does this mean that the Governor of the Grand Canal is not very loyal to Your Majesty?

But now is not the time to think about these things, meeting people is more important.

After Shen Zheng explained to Wu Lizheng some precautions regarding pounding the soil, she returned to the county school with Yu Shizhang and others.

Yu Shizhang kept instilling ideas in her along the way: "Don't be timid or too arrogant when we get here. No matter what happens, you will have Benbo's support."

Shen Zheng nodded heavily and flattered, "Master, you are so nice."

Before Yu Shizhang could respond to her flattery, she turned to Shen Xingjian and said, "Sir Shen, we agreed that you come to bargain, and don't leave later."

Shen Zheng inexplicably said this with the momentum of "Don't leave after school".
