Shi Zikang threw the stone in his hand to the car and said with a smile: "After all, this stone is at the back of the house, if it is not enough at that time."

"Let's come over and pick up some more. When the car is full, let's go back and start paving the road. ”

"Cheng, I remember that there was still a lot of rammed earth left when Uncle Wu's house was raised.

"I'll go to their house and fetch some later." Shi Zijian said happily.

"What is rammed earth? Do you need to use rammed earth to pave the road? Qing Dai was a little puzzled.

Without waiting for Shi Zikang to speak, Ah Huan took the lead and said, "I know, I know."

"Rammed earth is used to build houses, and my father said that a house built with rammed earth is strong."

There was one rare thing that she knew that Qingdai didn't know, and Ah Huan seemed extremely happy.

Looking at Ah Huan's look of begging for praise, Qing Dai did not hesitate to praise: "Ah Huan knows a lot." ”

"Ah Huan is right." Shi Zikang on the side also smiled and nodded when he heard this.

Glancing at Qingdai, he explained in detail: "Rammed earth is mixed with red mud, coarse sand, and lime blocks to form a kind of triple soil.

"Whether it is to build a wall or pave a road, if there is no rammed earth, the stone is not firmly inlaid, and it is easy to step into the soil......"

Under Shi Zikang's explanation, Qingdai also understood that the so-called rammed earth is actually equivalent to the existence of cement in the current building.

And this dynasty also has another substitute for cement, called glutinous rice lime mortar, which is much stronger in strength and viscosity than rammed earth.

However, the cost is relatively high, and people like the Shi family can't afford it.

After knowing this, Qingdai was also a little embarrassed.

She had just thought of paving the road with stones, and nothing else.

I didn't think about the need for cement to pave the road, and thought that it would be enough to just put the stone into the mud.

Fortunately, Shi Zijian and others understand this, and Uncle Wu's family also has achievements and rammed earth.

Otherwise, his behavior of running to pick up stones in such a hurry would be in vain, and it would be a waste of everyone's time.

This rain comes and goes quickly.

While everyone was picking up stones, the red sun was already hanging high in the sky.

After the rain, the sky was clear, and under the sunlight, the traces of water that had been left on the ground gradually disappeared.

After filling the last cart of stones, Qing Dai and her party also stopped their 'work at hand' and followed Shi Zijian home.

When Qing Dai and the others arrived home, Shi Zhongyi had already taken advantage of their efforts to pick up stones to clean up the ground in the yard.

"Dad, you can rest." Shi Zijian said while upside down the stones on the cart: "This ground is still wet."

"I can't pave it now, I'll go to Uncle Wu's house to pull some rammed earth back, and when it's almost done, let's start again."

"I know, I know, you go to pull the rammed earth first, I will first plane the soil that should be planed, and compact the soil that should be compacted."

"I'll go, you can rest." Shi Zijian said without delay, and pushed the empty car out of the door.

"Dad, let's go to the meeting, I'll do these things." Shi Zikang saw that Shi Zhongyi had no intention of stopping, and also opened his mouth to persuade.

"It's okay, I'm not tired." Shi Zhongyi smiled: "Although it is not difficult to pave the road, it is not easy to pave it.

"I'm much more experienced than you in this area, how to dig this soil, how much to cut and how much to keep.

"I just need to know it at a glance, and it doesn't bother to let you do it, but I still have to ask questions."

Shi Zhongyi said as he spoke, and the work in his hands did not stop at all. Shi Zikang saw that he couldn't persuade him, so he didn't say anything more, and only helped work on one side.

In just a few moments, the two of them had roughly sorted out the places where the road would be paved for a while.

Qing Dai looked at the 'path' in front of her, which had begun to take shape, and her mood was also very wonderful.

Happy said: "Grandpa, we are also here to help, what should we do?" ”

"Yes, yes, yes, I'm going to help too!"

"Me too, me too, I can walk the road I built every day in the future!"

"Hahaha, want to help?" Shi Zhongyi turned his head and looked at the few eager children in front of him.

After thinking about it, he smiled and said, "Then you can do the compaction work, step the place where I have plowed the soil, and step on it tightly." ”

"Okay." Ah Huan said, and was the first to step on the place where Shi Zhongyi had dug the soil.

He stumbled twice and asked with a smile, "Grandpa, do you think you stepped on it like this?" ”

"Hahaha, yes, yes!" Shi Zhongyi said happily: "Ah Huan is a little hard, but you can step on it." ”

"I know, Sister Qingdai, Sister Miaomiao, big brother, you guys come too."

When several people heard this, they didn't delay, and they all went towards Ah Huan, and according to Shi Zhongyi's words, they stepped on the ground vigorously.

This seemingly simple action was not expected to be more tiring than picking up stones.

After just a moment's effort, Ah Huan, who was still enthusiastic just now, was already a little wilted.

Since her cultivation, Qing Dai has not only improved her physique a lot, but also rarely felt tired.

Now that I keep 'stepping on and stepping on', I repeat it a lot, and I can't stand it.

Even her physical fitness can't stand it, let alone the delicate Miao Miao on weekdays.

Before she could step on it a few times, she only felt that her legs were not her own.

However, seeing that Qingdai and Ah Huan did not give up, she was embarrassed to say that she was tired, so she could only repeat the action mechanically.

Shi Zijian came back with rammed earth, and at a glance he saw A Huan and a few people mechanically jumping in the yard.

"What are you doing here?"

"We're helping." Ah Huan said weakly: "Grandpa said to compact, let us step on it." ”

"Hahaha, it turned out to be compacted, go and rest when you're tired, I'll just press it later."

"Dad, you don't know, this is tiring to step on the ground, we only stepped on this point for a long time.

"While I'm still strong, I'll help you step on it more." Ah Huan said intimately.

When Shi Zijian heard the news, he didn't say much, and only put the rammed earth in the car into the open space.

I didn't know where to find a large wooden hammer, and said with a smile: "Just use this for compaction, it's much easier than you stepping on it like this." ”

"Grandpa?" Shi Qingyang on the side stopped jumping and said in disbelief: "You deliberately tricked us? ”

"Hahaha." Shi Zhongyi looked at the panting few people and laughed a few times.

"I'm not looking at you just because you're so energetic that you want to find something to do for you.

"It's not a joke, don't say it, what you stepped on is much tighter than this hammer."

Hearing that the fruits of his labor were praised, the depression in the hearts of several people suddenly dissipated.

Said proudly: "That is, how hard we step on it, it can't be better than this hammer." ”

"I'm tired after stepping on it for a long time, so let's come over and drink some water and take a breath."

Hearing Yun Rong's call, Miao Miao, who was already exhausted, was suddenly overjoyed and hurriedly said, "Let's go drink water first." ”
