Old man Xiao was silent, as if he was considering the feasibility of what Li Chengqian said.

And Li Chengqian didn't want to give Lao Xiao too much time to think about it, and continued to speak: "The car is on the same track, the book is the same, and the people are on the same paper, this is the way to strengthen the country." There are dozens of units of measurement in my Datang, don't you think that you should unify them? ”

"This ......, wait for the old minister to think about it." Xiao Yu stroked his beard under his chin and said slowly.

Think about it? Li Chengqian laughed secretly in his heart, this old guy really regarded himself as a 9-year-old doll, and even played a trick of clichés.

Setting a standard to be followed by the whole country is a great opportunity to become famous, and as long as someone asks how this standard came about, someone will mention his formulator.

Speaking of which, it can be regarded as another kind of history to leave a name, such a big thing Li Chengqian didn't believe that Old Man Xiao was not interested.

It's one thing to be interested, it's another thing to start with it, this old Xiao is obviously using the name of 'think about it' to set Li Chengqian's words, I want him to say more, and it will be easier to operate in the future.

After all, if you want to formulate a unified weights and measures, you can't do it without Li Er's approval, it's always good to be more prepared, at least Lao Li can have some words to say when he asks.

However, Li Chengqian is not the Li Chengqian when he first arrived in the Tang Dynasty, and he didn't just sleep in the court for half a year, so of course this kind of trick of wanting to capture and indulge in the past can't hide from him.

Almost as soon as Old Man Xiao's words fell, Li Chengqian jumped down from the chair, bowed to Old Xiao and said, "If the boss thinks about it first, wait for Chengqian to go to his father and the emperor, and then ask the old man to come over to discuss." ”

Then he turned around and ran.

"Prince, His Royal Highness the Prince." There was the shouting of Old Man Xiao behind him, but the thunder was heavy and the rain was small, and he was not as confident as in the past.

The human brain hole will always be opened at a certain moment, and Li Chengqian's brain hole is now open, similar to Newton's brain hole being chiseled open when the apple fell.

Li Chengqian, who left the small courtyard where he was talking to Lao Xiaoyu, had already stopped, and began to slowly walk towards Lao Li's Lizheng Hall, Lao Xiao didn't catch up, he was obviously hit by the cake he painted, and accepted it.

Otherwise, with the rude behavior of turning around and running just now, Lao Xiao would chase him out of 18 miles and catch him and preach him.

At this time, Li Chengqian faintly had a kind of enlightenment, a kind of enlightenment as a superior.

The hustle and bustle of the world is all for profit, the hustle and bustle of the world is for profit, and the court is above the princes, who has no selfishness? Which has no desire? As long as you can grasp it, control and use it, the crown prince should not be too easy.

If you want to be famous through the ages, then give him some inspiration and ideas, Li Chengqian, who has more than 1,300 years of advanced knowledge, does not believe that he cannot satisfy them.

If you want to leave a clear history, then give him the opportunity to admonish, Li Chengqian, who does not make big mistakes every day and keeps making small mistakes, believes that let them admonish them every day and admonish them until death, and they are afraid that they will not be able to change half of their stinky problems.

If you want to be meritorious, then let them go to war, there are many enemies around Datang, which is enough for them to kill until they are soft.

If you want money, then give him money, Li Chengqian has a lot of ways to make money in his head, and he is afraid that he will not be able to make it all.

If you want power, then let him be the prime minister, under one person, above ten thousand.

But there is one point, that is, you must be obedient, otherwise you can give them back, and you can naturally take it back.

As for those who have no selfishness and no desires, kill them.

Because the entire Tang Dynasty only allows one person who has no selfishness and no desire, and this person is the crown prince - Li Chengqian!

With enlightenment, Li Chengqian felt that his whole person was much more relaxed, and those who were especially familiar with him would even find that there was a trace of inexplicable changes in him.

"Son-in-law, see father." According to the rumors of the inner servant, Li Chengqian entered Lao Li's office and greeted him honestly.

At this time, Lao Li seemed to be tired, and was sitting on a rocking chair resting, drinking slowly with a bowl of tea soup in his hand, and Li Chengqian's throat twitched.

Datang's tea is really not drunk by people, not to mention a lot of tea foam, but also add things to it, when he first arrived in Datang, Li Chengqian tried to drink it once, and only that time.

It feels needless to say, anyway, Li Chengqian hasn't touched that thing since that time.

"Sit down." Lao Li raised his finger and pointed to the chair not far away and said to Li Chengqian.

"Whoa!"

"What's the matter with this visit?" Li Er lowered his head and took a sip of tea soup and asked casually.

Li Chengqian smiled hesitantly, made a self-righteous and cute expression, and then said: "Father, look at what you said, can't the sons come to see you?" ”

After Comrade Li returned the same 'hehey' to Li Chengqian, he shook his head and didn't speak again, just slowly sucking his tea.

"However, Erchen wants to recommend someone." Li Chengqian, who was despised by Lao Li, pouted helplessly and spoke again.

"Who is it?" Lao Li asked quietly.

"Young Master Prince, Xiao Yu." Li Chengqian said calmly.

"Poof" His Majesty Li Er, who had just sucked a sip of tea soup into his mouth, couldn't hold back all of a sudden, and squirted out all the soup in his mouth.

Xiao Yu still uses your little doll to recommend? I don't know that the old man is talented? Li Chengqian's answer was too strange, and after Lao Li coughed for a long time, he didn't know what to say.

After a while, he asked, "What do you want to recommend him?" ”

Lao Li's state frightened Li Chengqian, but he just recommended himself, so he wouldn't have such a big reaction?

"Redefining Weights and Measures."

"Why?" Lao Li asked with a frown.

"Most of my Datang's units of measurement are too vague, and in my Datang's ordnance, the parts of the bed crossbow are not interchangeable, which is a problem in itself. If the unit of measurement can be unified, Erchen thinks it can be solved. Li Chengqian answered Li Er's question in a good time.

And the example of the bed crossbow was heard by Cheng Fairy when he complained some time ago.

"Unifying weights and measures can really solve the problem of parts not being interchangeable?" When it comes to military affairs, Li Er can't help but get serious.

"To solve part of it, Erchen asked the carpenter, the wood is in different environments, there will be different changes, so if you really want to achieve all the interchangeability, then you must use iron."

Some time ago, Li Chengqian liked those strange and ingenious things, and Li Er knew this, so it was not strange for Lao Li to be able to say the above words.

It's just that what makes Li Er curious is why Li Chengqian recommended Old Man Xiao instead of the Ministry of Industry, so he immediately asked, "Why Xiao Yu first?" ”

Li Chengqian glanced around the room, and said mysteriously: "Erchen wants to find something for him to do, so as not to chase after my ass every day." ”

"Poof" Comrade Lao Li was choked for the second time, coughing and speechless, but pointed fiercely in the direction of the gate, the meaning was obvious: get out of here.
