Printing is divided into two aspects: one is printing technology, and the other is raw material - paper.

The paper used in Dakang Dynasty is naturally not as good as copy papers in later generations. They are mainly used together with hemp paper and velvet paper. Both are paper categories that have become more perfect after hundreds of years of invention and improvement.

From the perspective of the ancients, these advantages are completely sufficient.

In Liu Mingqi's opinion, if there was no particularly good technology and the popularity of fountain pens, there would be nothing wrong with using paper to print books now.

Because even the big shots such as Wang Shusheng, Song Huizong and others in their previous lives used these papers to write and draw, can't they print them?

But, this does not mean that Liu Mingqi has no idea.

His idea was not related to printing, but was also associated with something else.

Speaking of the paper used to use the toilet now is far inferior to that of later generations.

That kind of hemp paper is too rough and it is not comfortable to wipe it at all. If I wait until I am thirty or forty years old and my hemorrhoids grow, and then I will use this kind of paper, wouldn’t it be very sad?

As a PhD in Physics and Chemistry, it’s time to bring real toilet paper to the people of Dakang Dynasty!

I have no choice but to do this for my father, for my mother, and for my unborn children!

Scientists all have quirks of divergent thinking.

But this is not shameful.

Many great inventions come from by-products of the original experiment.

For example, the blessing of the biggest man in human history, Viagra, wasn’t it just that when developing a medicine to treat cardiovascular and cerebrovascular diseases, I suddenly discovered that this medicine would make all blood rush to another key part, and then create it?

That guy made billions in 20 years with this invention alone! And it was US dollars!!

Therefore, it is completely reasonable for Liu Mingqi to think of inventing toilet paper when printing "Liang Zhu".

Don’t underestimate the toilet paper industry. It requires basic mechanics, physics and thermodynamics, mechanics, chemistry, etc. Anyone who can fully build this structure must be in a mature industrial society.

Liu Mingqi could not have invented the entire modern toilet paper industry. He could only use his own knowledge to create a simplified version.

Otherwise, he would not be able to make a wood crusher first.

He can't make a hot pressing roller machine.

Fortunately, these can be replaced by a clumsy method.

Liu Mingqi then brought Dazhu and Chi San to Xiaoge Village outside the city.

Not far from the official road, a strong smell of pig stinking came towards me.

When he rode to the entrance of the village, Liu Mingqi still saw a group of little kids running everywhere, a field that was gnawed by locusts, and a piglet walking lazily on the hill next to the village.

Seeing them, Liu Mingqi looked kind.

What a pig, eat well and grow well at this time.

In another three or four months, you will become all kinds of delicious food in Xiaoye’s bowl.

When Chi San saw Liu Mingqi like this, he was frightened, "Criminal, don't you really want to eat pork, do you?"

"You don't understand." The boy withdrew his eyes, "Pork is a delicious food on earth. From now on, you will definitely beg me every day and ask me to eat it for you."

"hehe!"

Chi Sanxin thought, even if I starve to death, I would never eat such stinky meat.

While the three people riding a tall horse were talking, an old man and a half ran over excitedly.

"Your Highness! Your Highness! Are you here?"

Mummama Zhao Youjin smiled so hard that he showed his mouth full of yellow teeth.

"I'll take a look at you and take a look at my pigs." Liu Mingqi smiled.

"We are so energetic about these little pigs!" Zhao Youjinyao pointed to the hill opposite, "They took care of them all day long, and even stayed in front of the pigpen at night. Look! How strong are these little pigs?"

Zhao Youjin is not stupid. What Liu Mingqi said should be listened to inversely.

The boy nodded.

He also saw it just now. Under the sunlight, these piglets are indeed more energetic than ordinary piglets, and they have a little more meat.

I have to say that the people in Xiaoge Village are still well taken care of.

There are a total of 107 little boars here. In fact, thirteen of them died because they were not proficient in cutting skills. Then they bought twenty more to cut, and finally they made up so many.

Tian Rong bribed several villagers from Xiaoge Village and asked them to report at any time.

The reason is not to want to lose the care fee of five taels of silver per pig, but to prevent them from feeding the pigs in the past.

Because these pigs are nine out of ten to get into the little prince's belly, how could they be raised in such a dirty way?

As a result, the result of the report from these villagers was that Zhao Youjin and others were feeding pigs honestly without any negligence or carelessness.

Think about it, too.

That day, Mr. Beixiong Hou was beaten to the point of being beaten by Miao Yan and almost sentenced to death. This tragic shocked Zhao Youjin and a group of fellow villagers who were with him.

Liu Mingqi can even be deceived by Prince Beixiong. It is conceivable what will happen if a group of mere villagers annoy him.

So everyone is honest.

After all, working for Prince Yu’s Mansion honestly can not only earn lard money, but also receive a huge reward of five taels of silver per pig. What’s wrong with it?

...

Liu Mingqi got off the horse and asked, "Zhao Cunzheng, do they react to the feed mixed with locusts?"

"Haha, don't say that the feed you matched, plus locust powder, made the pigs eat happier and their appetites much bigger." Zhao Cun said with a gaze, "If this continues, it is possible to increase to about 250 kilograms in seven months."

The boy smiled.

In fact, about 200 kilograms of pigs are enough for pigs to be slaughtered, but to meet the standard of fat pigs, you have to raise them for one or two more months to let them grow fat, that's better.

Without fat, where can pigs be called pork?

The boy used to purchase locusts without restrictions. In addition to giving them food to ordinary people, he placed them in bamboo baskets, hung them on clothes rails, exposed them to the sun, and directly dried them.

After drying, grind it into powder and then add it to the pig feed to make the pig grow better.

Now it seems that this strategy is quite successful.

Besides, doing this can also save a large amount of locust powder so that it will not waste more. After all, it was collected by Liu Mingqi with real money and silver.

"Where is your oil refining?" the young man asked again.

"This is not good!" Zhao Youjin sighed, "Everyone has almost no food, how can they make these pigs fill? They are slaughtered one by one, and now they can no longer be supplied to the house."

Too.

Recently, the lard received by Prince Yu’s mansion has been less and less.

The farmers slaughtered pigs to eat and sell, but it was only the first period of the locust plague, and they could not turn into pigs after that.

Only those richer villages can slowly slaughter.

Lu Gui and others, who were responsible for purchasing lard, are complaining now. The amount of oil they collect every day is less than one-third of the original one.

Xiaoge Village is not as poor as expected, but the villagers are used to being poor, so when there is a locust plague, they will immediately slaughter pork to sell. While selling it at a good price, they can also save more food.

If Zhao Youjin and the others had not been taking strict care of the pigs that Liu Mingqi had fostered would have been envied by the villagers.

Of course, because there is a lot of locust powder, the villagers ate a lot of locust powder, and Zhao Youjin would not say anything about it.

The common people have their own wisdom.

They rarely eat rice on weekdays, most of them are steamed buns and wild vegetable porridge, and they only eat some meat during weddings and funerals, or during the Chinese New Year and Festival.

This is also the reason why they slaughter pigs as soon as possible.

Even though half of the pigs eat the filth in the toilet, many of them eat the weeds in the surrounding mountains and fields. At this time, pigs cannot compete with people for food.

Eat less steamed buns and drink more wild vegetable porridge. Even if the grain prices have more than doubled during this period, the impact on them will not be very big - of course, this is only limited to the indigenous people around the Imperial Palace.

However, the food they planted is definitely nothing, and most of the harvest this year has been lost.

Liu Mingqi asked, "After this period of time, will you still raise pigs?"

"Definitely!"

Zhao Youjin nodded without thinking, "Now all the food has been wasted. Although there is a subsidy for feeding pigs in the mansion, it is also a transaction. We still have to raise pigs and then sell oil and meat to make money. Unfortunately, the lean meat has increased to twenty cents per pound during this period, and we have not caught up with the good time!"

Most villages immediately chose to kill pigs and sell them with pork, for fear of wasting food and others would not be able to afford pigs in the future. If it weren’t for the panic of many people during that period, the price of pork would have fallen strangely.

Now the price of meat is kept at 20 cents per pound. In fact, most of the reasons are thanks to the people who slaughter pigs early, otherwise the number will be reduced.

The boy laughed again when he heard this.

This is the benefit of the economically diverse commodity society, which allows farmers to have multiple choices. Even if the food is not enough, they can raise pigs to make up for the losses.

If you just look at the weather and eat, even if Da Kang Chao is very rich, you can't withstand the disasters again and again.

After a pause, Zhao Youjin also asked, "Your Highness, I heard that Jiangnan has a great harvest this year. By October, Jiangnan will transport a large amount of cheap bran. Is it true?"

"Um!"

Liu Mingqi replied clearly, "The price is less than one-third of the food, and there are many."
