Cai Ji and Wei Tu respectively reported what they were doing to Cao Shuo.

While the two were talking, Zhu Ao walked in: "Childe, the wine and food are ready." ”

"Let them send it up." Cao Shuo commanded.

Zhu Ao withdrew.

Cai Ji and Wei Tu looked dazed.

"Childe, what is the ...... of wine and food," Cai Ji asked puzzled.

"When you two come back, I can't help but entertain you." Cao Shuo said: "There have been a lot of things recently, and I don't have more time to go to Lingyun Pavilion. ”

"The two of us have been with Childe for the longest time." Cai Ji said: "When we come back, Childe doesn't have to care at all." ”

"It's because you've lived the longest with me that I care." Cao Shuo smiled: "You two don't excuse me anymore, talk while eating." ”

After a while, several maids brought food and wine.

"You both said what you were doing." Cao Shuo asked the two of them: "Did you encounter any hardships when you did specific things?" ”

"The most troublesome thing I've encountered is polishing bluestone." Cai Ji said: "Stone is different from soil, if the soil wants to be smooth, you only need to shovel a shovel and pad it, but the road paved with bluestone has to be polished a little bit. When a road is built, I don't know how many times it has been polished when it can be used. Many craftsmen would rather carry the stone than polish it. ”

Cao Shuo nodded, and he said to Cai Ji: "It is indeed time-consuming and laborious to pave the road with bluestone, and I have also seen the road you paved. Exquisite must be exquisite, but it takes me how many years it takes to pave a road. ”

"That's what Childe said." Cai Ji sighed and said, "It would be nice if I didn't have to work so hard." ”

Talking to Cai Ji about the bluestone paving road is not suitable, Cao Shuo suddenly remembered something - cement.

More than 2,000 years later, cement is widely used in the construction industry and road construction, although cement roads are not as durable as asphalt roads, but the paving process is much less worry-free than bluestone roads.

If cement can be made, Cai Ji's paving speed will be more than ten times higher than it is now.

"What you want is a material that you can use to pave roads quickly." Cao Shuo said: "I will go on an expedition in a few days, and the craftsman workshop has been relocated to Penglai. After I pacified Xiliang, I went to Penglai to study with the craftsmen. ”

"Childe can even make these?" Cai Ji was stunned.

"As long as you put your mind to it, there is nothing in this world that is impossible to make." Cao Shuo smiled slightly and said to Cai Ji: "After I return from Xiliang's victory, it won't take me three or five months to develop new paving materials for you." ”

"I'll thank the craftsmen first." Cao Shuo gave a promise, and Cai Ji hurriedly got up to thank him.

"It hasn't been built yet, and it's a little early for me to thank you." Motioning for him to sit down, Cao Shuo looked at Wei Tu again: "Did you encounter any difficulties in touching the gold camp?" ”

"There is no difficulty in touching the Golden Camp Road." "You don't need anything special to go to the tomb, but sometimes when you walk in the tomb, a strange wind blows out the torches," Wei Tu said. ”

"So as long as there is no wind, the torch will not be easily extinguished?" Cao Shuo also understood what he meant.

"Exactly." Wei Tu replied: "The tombs seem to be closed, but in fact many of the tombs have patios leading to the ground, and the wind is poured in through those entrances. But if there is no torch in the tomb, it is impossible to move forward even half a step. ”

"I know what you want." Cao Shuo pinched his chin and thought for a while and said, "But this kind of thing is more troublesome than Cai Ji's needs, and I'm afraid you will have to wait for a long time." ”

"As long as Childe knows about it." Wei Tu said: "We all understand Childe's difficulties. ”

"It's not that hard to actually make." Cao Shuo said: "It's nothing more than adding a cover to the outside of the oil lamp, but the material for this cover is more difficult." ”

"I understand Childe's difficulties." Wei Tu replied.

Adding a cover to the outside of the oil lamp is easy to say, but Cao Shuo knows very well that it is not like that.

There were not enough conditions to make glass in this era.

The only thing that can be used to make a cover is crystals.

However, the value of crystals is extremely expensive, and only mineral deposits have been found along the coast of Xuzhou so far.

Dare to promise Wei Tu, it is nothing more than that Cao Shuo knows that there is a way to mine crystals.

However, he was not a craftsman, and he did not have many theories about gem polishing, so many things needed to be explored slowly.

If you can't polish the right crystal, you can't make a lampshade that can not only block the wind but also not affect the light through.

So he didn't say too much as he promised Cai Ji.

Cai Ji and Wei Tu had served by Cao Shuo's side for several years.

The two of them knew his temperament very well.

When they first met, they were a little reserved, and after a few glasses of wine, they no longer spoke as cautiously as before.

Cao Shuo also became more and more interested the more he chatted.

Before they knew it, they had drunk a little too much.

Deng Zhan and Zhu Ao took Cai Ji and Wei Tu out and sent them back to rest.

And Cao Shuo, escorted by several female guards, went to Da Qiao's residence.

When he came to the door of Da Qiao's residence, Cao Shuo vaguely heard two people talking in the house.

Listening to the voice, it should be two women.

Gently pushing the door open, Da Qiao's maid greeted him.

Seeing that it was Cao Shuo, the maid was about to greet her, but was interrupted by him.

Without letting the maid say anything, Cao Shuo walked lightly to the door of the inner room.

I saw Da Qiao and Xiao Qiao sitting together.

Little Joe was also holding a small clay vase in his hand.

"Come and smell it, how does it smell?" Da Qiao leaned his white neck to the side and asked Xiao Qiao to come up and smell it.

With his nose in front of her neck, Xiao Qiao sniffed it: "The taste is still a little wrong, I always feel a little spicy." ”

"How can it be spicy?" Da Qiao didn't believe it, took the clay bottle in his hand, poured something in the palm of his hand, and said to Xiao Qiao: "You turn your neck sideways, and I'll wipe some for you." ”

Little Joe obediently crossed his neck.

Big Joe wiped something from the palm of her hand around her neck, and then put his nose up and sniffed it as well.

"It seems to be, it's cool and smells, but it's very comfortable to wipe on your body." Da Qiao said: "Let's think about it again, the husband is about to go on the expedition in front of him, and if he can't make the flower water he wants, he will always be worried." ”

Cao Shuo understood that the sisters were pondering the method of flower dew.

The two of them should be wiping flower water on their necks.

"You are both women, how can you smell good and bad?" Seeing this, Cao Shuo raised his feet and entered the inner room: "If you want to hear something, you have to come too." ”

He spoke suddenly, and both Big Joe and Little Joe were taken aback.

The dew water bottle in Da Qiao's hand almost fell to the ground.

got up and saluted Cao Shuo, and Da Qiao said with some complaint in his tone: "The husband suddenly spoke, which scared people so much that he almost hit the bottle." ”
