Although Li Shimin agreed that Li Chengqian would set up his own paper bureau.

But Li Shimin forgot the most important thing.

Money......

Just like last time shipbuilding.

This time, he did not allocate funds to Li Chengqian.

"Father's ......"

"The last time you built a ship, you didn't give me an allocation."

"You're going to have to give me a little bit this time......"

Li Chengqian looked at Li Shimin bitterly.

Li Shimin didn't even raise his head, and looked at the fold in his hand.

"Don't think I don't know, your uncle gave you this season's dividends some time ago."

"You have so much money, isn't it enough to open a paper bureau?"

Hearing this, Li Chengqian was anxious.

"No, Father......"

"Erchen is doing something for you this time, and he has to make household registration books, print books, and so on."

"These are a lot of expenses, you can't just give them nothing......

"Have you made the household register?"

"Is the book printed?"

Li Shimin finally glanced up at Li Chengqian.

"If you don't make it, don't tell me it's useless."

"If you make it by then, I will naturally reward you accordingly."

"It's a big deal, I will buy it at the market price."

Just as Li Chengqian wanted to say a few words.

Li Shimin waved him directly to shut up.

"If you don't want money, you don't have the courage to die."

"Rather than waiting to provoke me and beat you up, it's better to get out of here as soon as possible."

Li Shimin threatened fiercely.

But is this threat a matter for Li Chengqian, who takes money as his life?

Li Chengqian sat on the ground and began to play tricks.

"It costs money to make paper-making things, and it costs money to make venues."

"It costs money to hire workers, and it costs money to send guards."

"Even if my uncle and I started some small business, we didn't have that much money to spend on it."

"No, my father won't give me money, so I won't leave today."

Fool me?

Li Shimin sighed.

"Alright, don't fool around."

"Isn't there a vacant lot next to the shipyard in the north of the city?"

"Since you said there is no space, how about using it as a paper mill?"

Dealing with this old rascal is only good for tricks.

He also thought a long time ago that his old man would definitely play this hand with him.

So he didn't plan to ask Li Shimin for money at all.

Just thinking about a little more pit is a little.

So when he heard this, Li Chengqian was still a little happy in his heart.

But his face was still bitter: "Although the venue is available, I still have to hire labor." ”

"I can't take care of the workers, but in terms of guards, I allowed you to transfer the Qianzi Battalion, what do you think?"

Seeing him like that, Li Shimin felt funny.

Throwing the fold in his hand on the table: "If it doesn't work, then don't go." ”

"I happen to have itchy hands, so let me beat you up."

Beat yourself up?

This and that?

Li Chengqian jumped up directly from the ground, bowed down and said solemnly: "Forget it." ”

"There's still something going on in the son's mansion, so I'll leave first."

When the words fell, Li Chengqian turned around and ran, not giving Li Shimin a chance to react at all.

Seeing him running away, Li Shimin shook his head helplessly.

This stupid son......

……

After returning to the Qin Palace.

Li Chengqian began to make intensive preparations for the great cause of papermaking.

The principle of papermaking is not difficult for Li Chengqian, a science and engineering man.

The real difficulty is to make a more convenient instrument for extracting wood pulp.

Previously, he used a grinding disc to extract wood pulp.

But that thing was too backward for him.

What he wants to do now is the beater of the future.

To put it bluntly, the beater is just a lighter grinding disc.

In order to make this thing, Li Chengqian has made a lot of money.

Not only did he draw the drawings with his own hands, but he also stared at the whole process, for fear that the step was wrong.

At the same time as developing the beater, he also supervised the construction of the windmill himself.

The Windmill is definitely an epoch-making product.

Because if you want to see whether an era is underdeveloped, you only need to look at the many ways to obtain energy in this era.

In the era in which Li Chengqian lived, there was not only wind energy, but also solar energy, hydro energy, biogas, fuel oil, and so on.

But there is very little to take advantage of in this era.

Li Chengqian didn't think about making a steam engine or generator.

But the ideal is very plump, the reality is very skinny, and the forging level of this era is really poor.

It is impossible to make copper wires for generators, let alone accessories for steam engines.

If it weren't for that, with the personality of Li Chengqian, a science and engineering man, he would have made those things a long time ago.

I won't have to worry about kinetic energy every day.

That said, it's not too bad, at least in terms of wind energy, he's already starting to dig in.

Wind mills can not only make paper, but also grind rice, and also smelt and forge.

Either way, it's the first step to success.

For a long time to come.

Li Chengqian devoted himself wholeheartedly to research.

By the time the beater and a full set of papermaking equipment were built, it would be half a month later.

……

Mid-July of the second year of Zhenguan.

The epoch-making wind-powered paper mill finally began to operate with Li Chengqian's order.

Workers feed sections of green bamboo into the beater, where they are ground and heated to form the original pulp.

The puree flows out of the conveying pipe made of bamboo tubes and is evenly spread on the mesh.

The worker takes the pulp-lined mesh and cools it in cold water until it forms a moderately thick paper film, then fishes it out.

Then the paper film is folded one by one, pressed with a wooden board, and a heavy stone is placed on top to press the water out.

The last step is to dry the paper film by the fire, and when it is removed, it will be the finished paper.

{Received Surprise +19......} from Lu Wanjie

{Received Surprise +23......}

{Received surprise value from Cheng Huailiang +25......}

These people are all from big families.

Naturally, they had seen papermaking.

But this was the first time they had seen such papermaking.

Not to mention the bark hemp used for artificial paper next to it, and Li Chengqian used low-priced green bamboo to crush it in cost.

There is also a complete papermaking system, which is crushed in the papermaking speed.

When Li Chengqian said that making paper by himself would be several times cheaper and faster than others, they still didn't believe it.

But today, they see the time with their own eyes.

I just feel that my knowledge is too shallow.

Compared with Li Chengqian, it is simply heaven and earth.

Especially Lu Wanjie, who came over to join in the fun today.

When she looked at Li Chengqian, little stars began to appear in her eyes.

{Received admiration from Lu Wanjie +99......}

Hearing this system prompt, Li Chengqian couldn't help but shudder.

He now finally understands why some people say that he can owe everything in this world, but he can't owe a woman's love.

If you steal a woman's heart, you will really be remembered for a lifetime.

At the beginning, Li Chengqian hit Lu Wanjie with his idea for points.

He really didn't expect that Lu Wanjie would really be tempted by himself......

Hi......

Who called me so good......
