Bai Zhi listened to it and felt that he was very intimate: "I haven't thought about it even if you want to be thoughtful, but I just think it's good to eat it myself, so I want to share it with everyone." ”

Looking at the fruit I took a bite of, I thought that the dried fruit from such a fruit must be delicious.

"Zhi'er Now that your business is getting more and more on the right path, good things will come to fruition, and it doesn't seem that the idea of opening up the whole dynasty in the future will not be too much of a problem," whether it is what she sells, or her business ideas are something that none of these men can imagine, she is a business genius, if he is not successful, who will succeed?"

The two of them walked straight into the mountain, Bai Zhi had never been here, but when he saw his proficiency in walking in front, he was suspicious: "Duan Xun, are we going from this road correctly?" Can you find a rock? Some mountains are made of rocks, others are not, and if they go the wrong way, they have to waste a lot of time. ”

"Zhi'er, don't worry! The rocks in this mountain can be made into lime, so I think it shouldn't be a problem to use them to make cement," he didn't look back, and continued to walk, although everything is not a big thing, but it can benefit the people of the whole world, if cement can be made, it will be of great benefit to them.

Throwing away the apple core in her hand, Bai Zhi continued to follow him forward, she had always believed what Duan Xun said, the two of them didn't walk long before they came to a broken stone, because it was a stone mountain, there were broken stones everywhere, Bai Zhi had never seen how lime was made, so now she was not surprised to see these stones.

"Duan Xun, do you think these ten yuan are enough?" She consulted him.

"Well, these stones should be fine, but I don't know how to do the next thing, and I need your guidance," looking at the mountains of stones, Duan Xun's heart was surging, if these stones could really come in handy, it would be better than wasting them here.

Bai Zhi picked a piece casually: "Can you hold this stone?" ”

He stepped forward and bent down almost without any emotion, and lifted the stone: "It will not be a problem to take two more pieces of this size." ”

Bai Zhi looked around: "Hey, there seems to be a cave over there, why don't we go over there and have a look?" ”

Duan Xun threw away the stone in his hand and followed her to a cave not far away, Bai Zhi had always been puzzled in her heart, this cave looked so strange, like an upside-down funnel, it felt like someone had lived there.

"Duan Xun, I always feel that there is a smell of smoke in this cave, will anyone live here? Will we disturb people if we go in a hurry? She hesitated as she walked, if there were really people inside, wouldn't they be abrupt?

"Zhi'er, this cave looks really strange, there are many traces of smoke on it, but it doesn't look like someone lives in it, anyway, let's go first and take a look, if someone adds it, maybe you can ask them about the use of these stones," Bai Zhi and Duan Xun continued to walk inside only to find that this was originally an abandoned cave, although they couldn't understand what it was for, but from the pieces of red tiles and green bricks on the ground, they probably guessed that this might be a place to burn bricks.

But this is obviously a rocky mountain, and it takes a lot of earth to burn bricks, so wouldn't it be too wasteful to transport it to the mountain?

"Duan Xun, I didn't expect you people here to be so powerful, you see that this cave is really big, so wide!" Bai Zhi was very surprised that the things here were originally used to burn bricks, so it shouldn't be like this.

Although she couldn't figure it out, she couldn't guess the intentions of others, and since this place was abandoned, they might be able to borrow it!

A cool breeze blew, and goosebumps appeared on Bai Zhi's arms: "This place is so cold!" ”

She walked backwards, but suddenly stepped on a hole in the air: "Ah!! ”

The screams resounded throughout the cave, and she just accidentally stepped on one foot and fell into the pit, half of her leg stuck in.

"Zhi'er, how are you hurt?" Duan Xun stepped forward and took her hand to prevent her from falling down again.

"I'm fine, but I fell down suddenly, my leg hurt a little, you don't have to pull me, it's already the end, I won't lower it anymore, get me out now!" She felt like she was stepping on dust, her feet were soft, and she thought to herself that her clothes must be dirty.

Duan Xun didn't even think about helping her up from the pit, Bai Zhi's pink clothes were full of black things.

It was still very choking to pat it with her hand, and suddenly Bai Zhi laughed, although the dust was very choking: "Duan Xun, these seem to be cement, quickly take some and let's go out and have a look." ”

The smell of cement is a little choking, it smells very similar, and then touch it with her hands, it is very smooth, I'm afraid she guessed it closely.

Duan Xun also had a smile on his face when he heard what she said, and hurriedly took a handful and ran to the light, Bai Zhi followed closely behind, and he didn't care about dusting off his body.

After the two of them went outside, they were already gray-faced, with fine dust on their faces, Bai Zhi looked at the cement in their hands, although it was not as gray as in modern times, some were black and some were yellow, the two colors were very unevenly mixed together, Bai Zhi hesitated, maybe she guessed wrong.

"Zhi'er, are these cement?" Duan Xun couldn't wait to know the answer.

"This ...... The cement I've seen is blue-gray, but there are two colors here: black and yellow, so I'm not sure if she's ...... "She wasn't sure except that it tasted and felt very similar."

Cement is very sticky and long-lasting, and most importantly it is irreplaceable.

"Zhi'er, can we confirm it?" Duan Xun thought that if he could make something out of it, wouldn't it?

"That's right! Why didn't I remember? I wonder if there's more to it? If there are more, we can get some back, use these cement to build a few bricks, or pour out a cement mold, these things can be tested whether it is cement, "Although she has a lot of ideas, but they are all stealing some modern ready-made things, the more you see, the more ideas you have."

But the details still need to be helped by him.

Duan Xun ran to the cave again, only a few steps out, and thought of her standing at the door of the cave alone, not at ease, so he turned around and pulled her up and walked inside.

Bai Zhi watched his action, and her heart was moved and warm.

"Duan Xun, don't be so nervous, there's no one here, it's okay for me to stand at the door of the cave and wait for you," she said unintentionally, but the tip of her nose was already pantothenic.

"I know there's no one outside, and now in the mountains, there's no guarantee that there won't be wild beasts, it's always good to be careful," he said, full of cement, but he didn't forget her safety.
