It stands to reason that no one will come over at all in normal times, except for some soldiers or some officials from the Ministry of Industry who will come to these to compete for some materials or give work arrangements, where is there a chance to see so many Datang officials.

And at this moment, not only the officials, but even the family has someone to come to contact the Rubik's Cube, although this is not the credit of the prison himself, but Lao Liu still feels honored.

"Su Meng, give him something." Li Chengqian looked at Old Man Liu's old face smiling like a chrysanthemum, took a deep breath, and beckoned to Su Meng behind him.

Just came out of Li Xiaogong's printing workshop, a large number of printed materials are too heavy, Li Chengqian doesn't want the little beauties around him to run around the street with such heavy things on their backs, and calling Su Meng as a coolie is also the proper meaning of the question.

"What's that?" Looking at the huge bag that Su Meng put down, Liu Min asked inexplicably.

"Manual, from now on, every Rubik's Cube that comes out of the supervisor will be accompanied by a manual." Li Chengqian kicked the bag with his foot.

Liu Min reached out to open the bag with a question mark on his head, took out a thin instruction manual from it, looked at the only few pages and asked, "This, what can this thing do?" ”

"Don't care what you can do, just do what this palace tells you to do." Li Chengqian didn't have the heart to explain what happened to Old Man Liu, and after arranging the task compulsorily, he said: "Don't send out all the Rubik's cubes, leave some, and the palace will give them away." ”

"Whoa!" Although Liu Min didn't know what was going on, he didn't dare not listen to the prince's order, so he could only agree to it.

"Okay, you're busy, I'm going back." Li Chengqian arranged things properly and planned to leave.

"Hey, Your Highness, Your Highness, do you remember what you said about 'work, I-beam'?"

"'I-beam'? What's wrong? ”

"We got a few pieces, but we don't know if they fit or not." Liu Min rubbed his hands: "I just got it out in the past few days, and I wanted to go to the palace to report it, but I didn't expect to encounter the Rubik's Cube, so I delayed it." ”

Li Chengqian's face changed, and his eyes focused on Liu Min's face.

"That, that, Your Highness, Your Majesty, Your ......Minister" Liu Min quickly realized what the problem was, and the smile gradually disappeared, replaced by a face full of embarrassment.

"This year, all the holidays will be canceled, can you promise?" Li Chengqian's face was gloomy, and he was very dissatisfied with Liu Min, an old man's unclear public and private behavior.

"Answer, yes! Deserved, deserved! Liu Min also knew what kind of mistakes he had made, and he got rid of his complacency, and cold sweat kept falling from the top of his head.

The Rubik's Cube is just a toy, and no matter how much it is produced, it is not a proper job, and the trial production of steel explained by Li Chengqian is the most important. And Liu Min seems to have reversed all this, so it is understandable to be repaired.

"In two days, send everything to the Research Agency, all the rubble and some thick wood, you know?" After beating Liu Min, Li Chengqian continued to arrange the next things.

He didn't toss about the train for a day or two, the day he got out of the steam engine, he has been thinking about it, and now the rails are out of the test, and the difference is the test, as long as it can pass the test, then the railway can start construction.

Li Chengqian found that since he came back from Xianyang, it seemed that he had never had a day off, and he was running back and forth on the way to the old man's study every day.

No, I only came out of the old man at noon yesterday, and the next day I came again.

"Su Meng, don't believe it, that bird is new!" Li Chengqian, who didn't remember how many times he came to the old man's study, pointed to a sparrow falling on the eaves of a palace and said.

"Minister's letter." What can Su Meng say? It's straighter, but it's not stupid.

He won't argue with the 'boss' who is in charge of his job about the right or wrong of a thing, he doesn't care if the bird is new or not, anyway, as long as he answers according to Li Chengqian's meaning, it must be right.

However, this stunned person didn't know, in fact, Li Chengqian wanted him to say 'I don't believe it', only in this way can he have a chance to continue blowing. As a result, his sentence of 'minister's letter' blocked all the prepared statements of Li Chengqian.

I was depressed all the way to the old man's study, and after the report, I was called in by the old man, and I was greeted with a very impatient sentence: "What, what's the matter today?" ”

"That, father, the son wants to come to you for approval." Li Chengqian didn't seem to feel the impatience in the old man's tone, and rubbed his hands and salivated his face and said.

"Batch strips? What are you going to do? His Majesty Li Er took his attention away from the music in his hand and looked at Li Chengqian suspiciously.

"Path, father, the general has tried to get out of the railroad tracks, and Erchen is planning to do an experiment in the past few days, if the experiment is successful, then the railway from Chang'an to Luoyang can start to be built."

"If you want to build a railway, you can build it, don't say that you, the prince, don't even have the right to build a road, you weren't so cautious at the beginning." The old man was a little unimpressed by Li Chengqian's statement, and felt that this bastard must have some 'conspiracy'.

"Father, the railway is easy to repair, but it is not easy to do it manually, you have to give your sons some labor down, right? Moreover, land is required to build roads, and some special places even have to pass through people's homes, so what compensation must be given, right? In just a few words, Li Chengqian showed his fox tail.

The old man obviously heard his voice, and coughed lightly and asked, "Want money again?" ”

"Father, the money of the nobles has not yet arrived, and the project must be carried out as soon as possible, you see...... This time, it was borrowed from you, is it successful? ”

Although Li Chengqian had money, he did not intend to invest the money in the railway, so he could only ask the old man to borrow some of it first, and then return it to the old man if possible after they handed over all the money for the old goods in the future.

Of course, if it is not possible, the money can only be owed first, and then repaid when there is money. Or maybe it's been delayed for a long time, and it's impossible to say if you don't pay it back.

"Are you really sure? What kind of train can really do what you say? His Majesty Li Er asked uncertainly, until now, he still felt that what Li Chengqian said was too mysterious.

A car completely made of steel, driving on a road completely made of steel, without being pushed by people or led by animals, can drive by itself, and with Lao Li's wisdom, he can't understand how this thing works.
