Don't ask Lin Qingwan what she does with this paper, everyone who has been in her time knows that of course it is used to make toilet paper.

In this era, no one can use paper in a thatched house extravagantly, not even a nobleman like Lin Qingwan.

They use silk cloth, silk cloth that can be recycled.

This first kind of paper is also a failure, because it is too soft and too absorbent, but Cao Jin thinks it is good to become paper, so he also held it to show his aunt and grandmother, but he didn't expect this thing to have other uses.

Inspired by this, the two of them immediately went to research.

They already know which fibers are soft and absorbent, increase the proportions, and then reduce the others appropriately.

After trying it a few times, the soft toilet paper was really made, this thing was made of straw, and the cost was low, so the two of them sent a few large boxes directly to the other hospital.

In addition, two other kinds of straw paper of different quality were also improved.

Mrs. Xie and Lin Yubin both watched curiously, "Really only use straw?" ”

"There are still some potions," Lin Qingwan gave them the paper to try, "Although it is not as good as what we usually use, it is still possible to use it to practice calligraphy, and the most important thing is that the cost is low." Counting labor, a knife is less than five cents. ”

Mrs. Xie raised her eyebrows, quickly thought of the interests behind it, and asked, "Then how much do you plan to price?" ”

"Bawen."

Mrs. Xie frowned, "It's too big-eyed, I'm afraid that I will attract envy." ”

Lin Yubin pursed her lips, "Auntie can't overprice, what's the difference between that and the Zhao family's gluttonous building?" ”

Lin Qingwan nodded, "This is one thing, and the other thing is that I don't want to monopolize this recipe." ”

"What does that mean?" Mrs. Xie was surprised.

Lin Qingwan smiled and said, "I decided to pass on this recipe, and anyone who wants to make straw paper can use it." ”

"This ...... Why is that? ”

Lin Yubin's eyes rolled, clapped his hands and shouted: "This is wonderful, spread all over the world, who can do anything to us?" ”

Mrs. Xie knocked her on the head and said angrily: "Who is this crooked theory to learn from, I'm afraid that someone will hate your aunt even more by then." ”

Lin Qingwan smiled and said: "Let them hate it, I just want to buy the hearts of the poor students in the world, and it is also a little selfishness of mine, I hope that there are more and more people studying in the world, and there are more people of insight, so that the world can quickly settle down, and the people's lives may be better." ”

Mrs. Xie couldn't say anything when she stopped her, she sighed and said: "If this is selfish, then there will be no public heart in the world, I used to hear Erlang praise you, but unfortunately you are not a man, I thought it was you two children who made fun of it, but now it seems that I am short-sighted." ”

The world is stable, this is also what Mrs. Xie is praying for, it should be said that this is the wish of most people in troubled times.

Although they didn't know if it was useful, Mrs. Xie was unwilling to stop their efforts.

Lin Qingwan put aside the matter of the straw paper, "It's a pity that now is not the time to make it public, so let's wait a little longer." ”

The two of them knew that she was talking about the current rebellion of the displaced people, Lin Yubin sighed and said: "When will this matter be resolved, Sister Lu has been posting to me for two days in a row, and I haven't been able to go out." ”

Lin Qingwan reached out and touched her head and comforted: "Bear with it, wait for Zhou Tingshi to settle the displaced people and then go out." ”

Lin Qingwan saw that she was depressed, thought about it and said, "If you are really bored, come and give me a hand, it just so happens that I have something to do." ”

Lin Yubin pouted, what else could my sister-in-law do in the courtyard? Zuo is just some housekeeper settling accounts, she has learned everything, and she doesn't want to do it, it's not as interesting as reading a book.

Mrs. Xie smiled and watched the two of them talk, not asking what was the matter.

It's almost the New Year, she wants to copy the scriptures for her son, and during this time, in addition to coming out every day to talk to Lin Qingwan, and seeing the situation, she stays in the Buddhist hall to copy the scriptures.

Lin Qingwan also began to copy the scriptures after reading it, but she only copied the "Dizang Sutra", and she had to copy a total of three volumes.

Lin Yubin and Mrs. Xie read it, and only thought that her extra volume was for Yubin's mother, Shang.

Lin Qingwan didn't explain, but silently copied one more volume when she returned to the house.

This time, Lin Qingwan took Lin Yubin with her, but not for the housekeeper to manage the accounts, but for the bamboo paper in the courtyard.

The first batch of bamboo had been soaked in the pond water for more than 100 days, and just as the straw paper was made, Lin Qingwan decided to start the other processes today.

Lin Qingwan didn't plan to let Lin Yubin learn to make paper, but just let her see how bamboo paper is made, she washed the soaked bamboo with a mallet, and said: "Everything in the world is very strange, almost everything is changeable, the treatment method is different, and the things obtained are different, not to mention that things can be combined with each other." Before the paper came out, who would have thought that fishing nets, tree bark, rags, etc. could be processed and combined into paper that could record words? ”

"In the past, people in the world used tortoise shell, bronze, bamboo, and silk cloth as the carrier of words, and then there was hemp paper, and slowly, paper became the carrier of civilization, and the dark yellow hemp paper also became white rice paper, but it was not bad for a hundred years." Lin Qingwan handed the mallet to Cao Jin, and instructed him to penetrate the bamboo mallet and wash off the coarse shell and green skin, "Since the world can make rice paper, there are naturally other high-quality papers like rice paper, but people haven't made it yet." ”

Lin Yubin looked at the pond full of bamboo, it was hard to imagine that they could be turned into white and flawless paper like rice paper, "Is the bamboo paper that my sister-in-law wants to make is comparable to the paper of rice paper?" ”

Lin Qingwan smiled and bowed, "It won't be worse than it, just look at it." ”

"That's one of the reasons why you want to publish the recipe for the straw paper?" Because with better and more attention-grabbing bamboo paper.

"We can't be left to monopolize all good things," Lin Qingwan pointed at herself and her, "Although the titles of county lord and county lord on our body are somewhat useful, they are not enough to completely shelter us now. ”

Lin Yubin tilted his head, "Then why didn't my aunt tell Mrs. Xie?" I think she's a little worried. ”

"Because I don't want her to be embarrassed," Lin Qingwan smiled: "Mother, she is Xie Yang, and I am now Lin." ”

Lin Yubin opened his mouth slightly.

Lin Qingwan looked at her seriously and said: "Yubin, not all honesty is good, sometimes concealment is the best thing for each other, and she knows it in her heart." ”

Therefore, Mrs. Xie never asked about Lin Qingwan, Zhuangzi, the bookstore, and even when she practiced long-term work, she was more and more cultivating them into a ministry, she only couldn't see it, let alone ask.

Lin Qingwan would never ask about the Xie family as the daughter-in-law of the Xie family.

It's good for each other.

Even if the Xie family asks Mrs. Xie one day, she can confidently say that she doesn't know, because she really doesn't know.

Putting aside the bamboo pieces washed by the mallet, Lin Qingwan took Cao Jin and Meng Fu to carefully smear the well-mixed lime water.

The first batch of soaked bamboo, although not much, is not a lot.

The three of them worked together, and Lin Yubin was on the side, and it was not until the evening that all the bamboo was processed.

Lin Qingwan instructed Cao Jin and Meng Fu to put the processed bamboo into a specially made pot to boil, which was similar to the method of boiling salt, and was covered with a bucket.

Lin Qingwan thumped her waist and got up and said: "The next thing is to watch the fire, I will send a few useful subordinates to the two of you to help, you are divided into two shifts, day and night, this time you have to boil for eight days and eight nights, during which the fire cannot be broken, and bamboo and hemp can be produced after eight days." ”

After telling the size of the fire and some precautions one by one, Lin Qingwan took Lin Yubin and left.

Bamboo paper is the key to reviving the Lin family's bookstore, and it can even accumulate prestige for the Lin family, and Lin Qingwan has to pay attention to it.

Lin Yubin also noticed her aunt's solemnity, and couldn't help but pay more attention to the side hospital.

It's just that before the bamboo and hemp were boiled, something happened in the other courtyard first.

First, Zhuang Hu, who stayed at the intersection to guard the Qingfeng Teahouse, sent his youngest son back to report to Fang Datong, "Uncle Fang, my father said that a large number of people came from the east and southeast to see and surround him. ”

On both sides was the direction of the city gate, and there were many homeless people gathered there.

Fang Datong immediately said: "Don't go to the teahouse, go home and bring your mother and your sisters to the other courtyard." ”

He said to the people beside him: "Let the second child send a signal, so that everyone in the Zhuangzi can gather back and enter a state of alert." ”

He went to find Yan Hu again, "You take someone to investigate, come back as soon as possible, and if it is true, bring Yu Zhu with you when you come back." ”

Yu Zhu is the one who stayed at the intersection to guard the Qingfeng Teahouse, the kid broke his right arm, and his body was relatively weak, his mother was bleeding heavily when she gave birth to her little daughter, and her health has been bad, and there are many children in the family.

When the teahouse was built, Fang Datong and Lin Qingwan recommended their family.

Lin Qingwan didn't want to make money at all when she built Qingfeng Teahouse, but because she wanted more peace of mind out of stability in troubled times.

So the main task of Yu Zhu's family there is not to sell tea and do business, but to guard the intersection.

In addition to a few low hills here, there is only one high mountain in Qingfeng Mountain, Qingfeng Teahouse is two floors, and the lookout platform is on the second floor.

And now it's winter, the crops are harvested, everything is withering, and you can see farther.

Yan Hu was born as a scout like Fang Datong, he had better luck than Yan Hu, and his limbs were sound, but he was cut off by the enemy and cut off one of his ears and scratched his face, and now the scar is still very conspicuous, and it looks terrifying.

The soldier's face was hurt, and his ears fell off, but he would not have any future, so Yan Hu retired.

However, his ability has not fallen, but his ear power is better, and it is best for him to investigate this time.

Yan Hu took the order and immediately took two well-trained long-term workers to go out secretly.

Fang Datong went to report to Lin Qingwan, no matter whether it was true or not, he had to tell Lin Qingwan about this matter first, so that she could also prepare.

The Zhuangzi also moved quickly, and the long-term workers quickly went to check the traps and weapons, and quickly approached the courtyard.

The farmers and tenants packed up their belongings and moved them to the courtyard, leaving their homes for ambush by the long-term workers.
