Li Zhao was a little relieved, the "Book of Songs" collected poems from the early Western Zhou Dynasty to the Spring and Autumn Period, there are all kinds of poems in it, which can be described as a treasure of this period, not to mention this period, even for later generations to inherit the classics.

In my previous life, when I was studying, I knew very much about "Guan Ju" and "Pu Jia".

Such a treasure, if Li Zhao is allowed to discuss, he may be overwhelmed, but for the great Confucians of this period, it is not true, Tu'an Guo and them to discuss poetry is to find death.

"It seems that the brains of the Tu'an people are not good? Otherwise, how can you use Daqin's expertise as a problem? Li Zhao humored to himself, but frowned slightly the next moment.

Thinking so, since Tu'an Guo dared to attack the Great Qin of the Great Unification, would he be so stupid? Unlikely, poetry is not so simple.

However, this is something that Qin Shi Huang should worry about, not him, so he doesn't think about it anymore.

"You continue to inquire in the palace, and if there is any important news, come back and tell me immediately."

"Young master, don't worry, if there is any trouble, the thin dog will definitely come back as soon as possible." The thin dog is not as pretentious as Ah Chao, but is conscientious.

Li Zhao saw this in his eyes and was still very satisfied with him.

Soon after, Shen Gongzi sent someone to report, saying that he had selected the address of the cement workshop in Shanglin Yuan, built a cement kiln, and prepared sufficient materials, and asked him if he wanted to go to the scene for guidance.

Cement manufacturing is only, as long as you do a good job of grinding and burning, the defective products are stronger than clay, with the cheats in the department store, even if there is no him, Shen Gongzi can be successfully manufactured, at most calcined a few more times.

"Go back and tell Shen Gongzi that you need to keep in mind that you need to keep in mind the two grinds and one burn, and I won't go."

Shen Gongzi's work efficiency is very high, and he has completed the preliminary preparations in a short time, which is indeed unpopular, so he doesn't have to worry about it, and naturally he doesn't want to go both ways, which is very laborious and time-consuming.

"At the same time, he told him that during the cement production, the main body of the hydropower plant will be built."

Daqin had manpower, as long as it was not recruited, it could recruit craftsmen at any time, and no matter how poor it was, it could hire some long-term laborers to specialize in construction and forging.

He has already told Shen Gongzi that all these expenses come from Chang'an Township, as long as things are done well, it doesn't matter how much money you have.

"Yes, young master."

The man is gone.

The next day, Ah Chao also sent someone to report that the smelting technology had reached a new level, and copper smelting had begun, and it should not take time to refine the copper wire in the secret book.

Li Zhao is very satisfied, Ah Chao's ability to do things is also good, when he asked Ah Chao to smelt copper, he gave him a more advanced smelting secret, and let him smelt copper wire as soon as possible, at this moment, it seems that he is very dedicated.

The main equipment used to make copper wire in the previous society was a wire drawing machine, Daqin did not have a wire drawing machine, and Li Zhao was not ready to buy it from the store, so it was necessary to rely on manual wire drawing.

This is a technical job, without any experience in the early stage, it is very difficult to operate, but even so, the craftsmen dare to say that they can forge copper wire in a short time, which shows that they are particularly attentive.

"Very good, remember to remind Ah Chao that there are three kinds of copper wires, and the size must be distinguished, if the last one can't pull the wire, just give up and let it make the first two first."

Copper wires are large and small, and Li Zhao's requirements for Ah Chao are to manufacture three types, namely three millimeters in diameter, one millimeter and 0.3 millimeters.

0.3 mm is too small, it is difficult to pull out with the current technology, he does not require A Chao to be able to pull out, of course, it is best to pull it out, 0.3 mm copper wire is a homely copper wire, the usage rate is the highest, if not, it can only be replaced by one millimeter, although it is very power-consuming, but it is also a helpless move.

"Also, tell me when the copper wire is drawn, and I'll give you something."

What Li Zhao wanted to give was rubber.

Rubber is not produced in the Central Plains, and rubber did not appear in Daqin, it was introduced at the end of the Qing Dynasty, and there is no at the moment, but the shell of copper wire needs rubber to make wire skin, which can only be purchased from the store.

After arranging all this, he was about to continue drawing the blueprint, when the thin dog hurried back, and shouted from afar: "Young master, young master, good things have arrived, arrived." ”

Meddlesome?

Li Zhaozhang was confused, as if the word 'good thing' had nothing to do with him recently, so he stopped and waited for the thin dog to report.

The thin dog came to him, panting and squirming his mouth, "Young Master, Princess Yangzi invites you to enter the palace." ”

Well! Is this a good thing? It seems to be the same.

Li Zhao was secretly happy in his heart, but it was a little strange, entering the palace? Qin Shi Huang said that there is no will, he is not allowed to enter the palace, how can the princess invite him into the palace?

"Is it the princess's own will or does it have a will?"

"What the princess meant, His Majesty did not will, but the princess said that His Majesty acquiesced."

Acquiescence?

Li Zhao was surprised, His Majesty didn't let him enter the palace because he didn't want him to come into contact with Yin Yan, but at this moment, he acquiesced and contradicted himself?

There's weirdness in that.

But I don't think much about it, since it was Yin Yan who let him pass, there must be something important, even if His Majesty did not acquiesce, he was willing to take a risk for Yin Yan.

"Well, you go and tell the princess at once, and I'll be there after dark."

The reason why I chose to be dark was because I didn't want to be talked about.
