Bind the system and take your younger siblings to survive in the disaster years

The remaining unsteamed chrysanthemums were handed over to Mrs. Chen and Widow Jia, because Li Qingxiu saw many men picking up stones at the edge of the valley.

Those stones fell from the top of the mountain yesterday when the earth dragon turned over. Only then did Li Qingxiu remember that her stone house had not yet been agreed with Li Zheng on how to build it.

At this time, when Li Datian passed by Li Qingxiu holding a big stone, Li Qingxiu took a casual look and realized that the stone was special.

Li Qingxiu called to Li Datian who was walking forward. "Uncle Tian, ​​wait a moment."

Li Datian stopped when he heard Li Qingxiu calling him, turned around and asked, "Qingxiu girl, what's the matter?"

Li Qingxiu stepped forward and pointed to the stone in Li Datian's arms and said, "Uncle Tian, ​​can I take a look at this stone?"

"Okay, it's just a stone, there's nothing wrong with it." After Li Datian said that, he put the stone on the ground for Li Qingxiu to look at.

Li Qingxiu looked at it for a while and felt that it looked similar but was not sure, so he summoned the system: System, can you help me see if this stone is limestone?

【drop! The host's request has been accepted, and the host has three free opportunities to identify items every month. After three free opportunities are used, 500 points are required for each identification. Is the host sure to use it? 】

Li Qingxiu was very satisfied to see such benefits. She was not a top student and didn't understand many things, so she needed these three opportunities.

Li Qingxiu confirmed: Yes. I need to identify this big rock in front of me.

【drop! The stone is limestone. Limestone is a carbonate rock, usually light gray or blue-gray in color, and is the main raw material for making quicklime. 】

【drop! One free identification opportunity has been used, and there are two free identification opportunities left this month. 】

Li Qingxiu was overjoyed. She was about to build a house and was short of lime. As for quicklime, she also knew how to make it. This was all thanks to modern short videos.

Li Qingxiu looked at Li Datian and said, "Uncle Tian, ​​are there many stones of this color?"

"The stones at the foot of the mountain over there are all stones of this color. Aren't you going to build a house? I saw that the color of this stone is quite beautiful, so I brought it over." Li Datian pointed in the direction of the crack and said.

Li Datian thought that there was a crack there which was quite dangerous. So he said, "How about I take you over to have a look."

Li Qingxiu did not object. When the two came to the crack, Li Qingxiu saw that the fracture at the foot of the mountain was full of limestone, and the fallen stones were also limestone.

Great, there are so many lime rocks so we don’t have to worry about quicklime. She would later ask Li Zhengduo to send some people to bring these stones back to make quicklime.

After making quicklime, you can also make hydrated lime. Hydrated lime can be disinfected and sterilized, which is very needed in places where livestock are raised. Or if fruit trees are infested with diseases and insect pests, you can also apply a layer of hydrated lime slurry to achieve the insecticidal effect.

Li Datian saw Li Qingxiu looking at the blue-gray stones on the ground and smiling. He asked tentatively: "Qingxiu girl, are these stones treasures?"

Li Qingxiu smiled and nodded: "It's a big treasure. Please ask Uncle Tian to ask Uncle Li Zheng and his uncles to collect these stones."

When Li Datian heard this, he immediately smiled and said, "Okay, I'll call them here. Don't wander around. It's quite dangerous here."

After Li Datian finished speaking, he turned around and ran away without waiting for Li Qingxiu's reaction. Oh, mother! He discovered this precious stone, and this time he could make a contribution in front of Li Zheng.

Li Qingxiu looked at Li Datian's cheerful back and didn't know what to say for a moment. No, did he know what the use of this stone was and he was so happy?

Li Qingxiu looked around. There were limestone and some tall pine trees nearby, and nothing else was special.

Not long after, Li Datian hurried over with Li Zheng and his party.

As soon as Li Zheng saw Li Qingxiu, he hurriedly asked: "Qingxiu girl, is that stone you are talking about a big treasure? How can it be a treasure?"

Li Qingxiu grinned, revealing her big white teeth. "Uncle Li Zheng, this stone can be used to make birth lime. Do you think it is a great treasure?"

Li Zheng's face was filled with joy. "If lime can really be extracted, it will definitely be a big treasure. I have to build a house these days, and I am worried about what I will do if I don't have lime?"

The others were also very happy when they heard this, but none of them knew how to make lime, so they all looked at Li Qingxiu, and some asked what they were thinking.

Li Qingxiu came up with the old excuse again. "I've seen it in a book before, I can give it a try."

When Li Zheng heard what Li Qingxiu said, he knew that she must be sure. So he said excitedly: "Young pretty girl, since you know the recipe, tell me how to make it, and we will fully cooperate."

"It's not easy to say. Let me do it again and show it to you."

After Li Qingxiu finished speaking, she went to work as a carpenter in the straw shed and asked Li Gao for a few boards. Seeing that it was Li Qingxiu who wanted to use them, Li Gao was not stingy and gave him seven or eight pieces, saying that he would come back to get them if there was not enough.

Li Qingxiu took the wooden board to an open space not far from the limestone. He first dug two long grooves and placed a few wooden boards on top of the grooves.

Then he took a hoe and ran to dig loess near the limestone. Li Datian and several men saw this and stepped forward to help dig the soil.

Li Zheng also asked Li Qingxiu how much yellow mud he needed. If he needed more, he asked a few more people to help dig it out, which would make it faster.

Li Qingxiu thought that in the future everyone would build houses and raise livestock, so the amount of lime would be indispensable, so she nodded and said as much as possible, because it would be mixed into mud.

The men did not need to give formal orders and all came forward with tools to dig the soil. Some men went to the pond to fetch a few buckets of water and mix the yellow soil into a thin mud.

At this time, Li Yuqi, Li Yuhao and several young men were each carrying a large bundle of firewood.

Li Qingxiu took a look, hey! Just in time.

Li Qingxiu immediately stopped them and asked them to give him dry firewood.

When the boys saw this, they knew what Li Qingxiu was going to do again. So they all put all the firewood they had near Li Qingxiu, and then turned around to pick up firewood again.

Li Qingxiu spread a thick layer of yellow mud on the wooden board, and then used a branch to insert some holes in the yellow mud cake.

Li Dazhuang and Li Erzhuang heard that Li Qingxiu found a treasure here, and the brothers came over out of curiosity. As soon as I arrived, I saw Li Qingxiu tinkering with the yellow soil.

Li Erzhuang asked curiously: "Qingxiu, what are you doing?"

Li Qingxiu replied while keeping her hands busy: "I am building an earthen kiln!"

Li Zheng was afraid that the brothers would disturb Li Qingxiu, so he told them that Li Qingxiu was going to make lime, which surprised the brothers.

Li Qingxiu stuffed the dry firewood into the two grooves, picked up the fire stick and ignited the dry firewood. The current step was to dry and harden the yellow clay base to obtain the base of the earthen kiln.
