"Up the mountain?" Liu Sanlang asked, "Boss, what are we going to do up the mountain?" ”

Lin Yi said: "I will tell you slowly on the way, you can do what I say first." ”

"Yes."

Lin Yi waved his hand, and the two went out.

After eating at noon, Liu Sanlang came over, Lin Yi was already ready, and the four of them went up the mountain together.

Because the road up the mountain was basically a small road, Lin Yi and the others did not take a carriage, but walked to the mountain on foot.

Liu Sanlang asked: "Owner, are we looking for something when we go up the mountain this time?" ”

He went back and thought about it, before Lin Yi said that he needed mortar to bond the red bricks, and he went up the mountain, I don't know if it was to find the raw materials for the preparation of mortar.

Lin Yi nodded and said, "I want to find something, I told you in the morning, if you want the red bricks to be firm, you must use mortar to glue them, and we are going to the mountains now, just to find the raw materials to make mortar." ”

When Liu Sanlang heard this, he immediately pricked up his ears and said, "Then the owner, what raw materials do you need to prepare mortar?" ”

Lin Yidao: "There are a lot of raw materials needed to prepare mortar, including limestone, clay, slag, sand and gypsum, we go up the mountain today, is to first investigate, whether there is limestone on this mountain, if there is, we can make cement for the preparation of mortar." ”

"Oh, I know the clay and the sand, but I don't know what kind of stone this limestone is. And what is slag? And plaster? Liu Sanlang frowned, with a question mark on his face.

Tao Shiyi said: "Madam, is the gypsum in the medicinal herbs?" ”

Lin Yi nodded and said, "Yes, limestone is a kind of gray-white stone, which is a necessary raw material for making cement." ”

"Gray-white stones, I know where they are." Peach Twelve said excitedly.

Lin Yi's eyes lit up and asked, "Where is it?" ”

Tao Twelve said: "Once, Childe sent me to Gyeongbuk City on official business, where there was a mountain full of large gray-white stones. ”

"Gyeongbuk City, it's too far away." Lin Yi said: "This transportation is too inconvenient, it is best to find it nearby." ”

When Lin Yi said this, Liu Sanlang couldn't help but be a little worried, and said: "Dongjia, if there is no limestone nearby, what will we do with our follow-up work?" ”

Lin Yi said with a smile: "Don't worry, in nature, there is a lot of limestone, and it is found in many mountains. ”

"Oh, I see, so I'm relieved." Liu Sanlang patted his chest and mouth, as if he had put down a big stone in his heart.

Peach Twelve admired Lin Yi with a face, only to see him staring at Lin Yi, and said with starry eyes: "Madam, you are so powerful, you know everything, are these also written in that book?" ”

"yes, yes." Lin Yi is a serious way.

Peach Eleven thought for a while and asked, "Madam, can these things be used to make mortar right away?" It's okay to take some sand and clay, which is already very fine, and take some stones, such a piece by piece, how to use them to glue. ”

"You're stupid, of course you have to grind it into powder, mix it and mix it together, just pick it with water, haven't you ever played with mud when you were a child?" Peach Twelve rolled her eyes and smiled.

Peach Eleven was a little unconvinced, and said: "I naturally thought of grinding them into powder, but those gray-white stones are very hard, and I don't know how much effort it will take to grind them into powder." ”
