Don't ask Lin Qingwan what she's doing with this paper. Anyone who has been in her time knows that it is used as toilet paper, of course.

  In this era, no one could afford to use paper in the toilet, even a noble like Lin Qingyan didn't use it.

  They use silk fabrics that can be recycled.

  This first kind of paper is also considered a failure, as it is too soft and has too strong ink absorption. However, Cao Jin thought that at least it had become paper, so he brought some to show his aunt. He didn't expect that this thing would have other uses.

  Inspired, the two immediately went to study.

  They already know which fiber is soft and absorbent, heavy ratio, others just reduce appropriately.

  After trying several times, the soft toilet paper was finally made. This stuff is all made of straw, with low cost, and the two people directly sent a few large boxes to other hospitals.

  In addition, two other kinds of inferior grass paper were also improved and delivered.

  Mrs. Xie and Lin Yuhbin both curiously surrounded him, "Really just used straw?"

  "There's also some ink," Lin Qingyuan handed out the paper for them to try, "although it can't compare to what we usually use, it's still usable for practicing calligraphy. The most important thing is that it's cheap. Including labor, one knife isn't even worth five cents."

  Mrs. Xie raised an eyebrow and quickly thought of the benefits behind it, asking: "Then how much do you plan to set the price at?"

  "Eight Articles."

  Mrs. Xie frowned, "It's too grand, I'm afraid it will invite jealousy."

  Lin Yuhong pursed his lips, "Auntie can't just set a high price arbitrarily, what's the difference between that and Zhao's restaurant?"

  Lin Qingwan nodded, "That's one aspect, and another point is that I didn't think of monopolizing this formula."

  "What does this mean?" Mrs. Xie exclaimed in surprise.

  Lin Qingwan smiled and said: "I've decided to spread this formula out, whoever wants to make grass paper can use it."

  "This... why is this?"

  Lin Yuhong's eyes rolled around and he clapped his hands, shouting: "This is great! Let the whole world know about it. Who can do anything to us?"

  Mrs. Xie tapped her forehead and scolded: "Who did you learn this twisted logic from? I'm afraid someone will hate your aunt even more in the future."

  Lin Qingwan just smiled and said, "Let them hate it, I want to win over the hearts of scholars from humble families all over the world, and it's also my own personal wish. I hope that there will be more and more people reading books in this world, and with more knowledgeable scholars, the world can become stable sooner, and the lives of the common people may get better."

  Mrs. Xie interrupted, and the words that were about to be spoken could not be uttered. She sighed: "If this is selfishness, then there would be no selflessness in the world. I used to hear Er Lang praise you, and it's a pity you're not a man. I thought it was just you two children joking around, but now it seems I was short-sighted."

  The world is at peace, this is also what Mrs. Xie has been praying for, it should be said that this is the wish of most people in a chaotic world.

  Although it is unclear whether it will be useful, Mrs. Xie does not want to hinder their efforts.

  Lin Qingwan put aside the matter of the grass paper, "Unfortunately, it's not the right time to make it public yet, let's wait a little longer."

  The two of them knew she was referring to the current refugee crisis. Lin Yubin sighed and said, "When will this matter be resolved? Sister Lu has been sending me invitations for two days now, but I haven't been able to leave my house."

  Lin Qingwan reached out and patted her head, comforting her: "Bear with it for now, once Zhou Cishi settles the refugees, we can go out."

  Lin Qingwan saw that she was feeling down and thought for a moment before saying, "If you're really bored, come help me with some work. I have something to do anyway."

  Lin Yuhong pouted, what else could Xiaojie do staying in another courtyard? At most it was just some household chores and accounting, she had learned them all and didn't want to do them, it's not as interesting as reading books.

  Mrs. Xie smiled as she watched them talk, without asking what it was about.

  The New Year is approaching, she wants to copy scriptures for her son. During this period of time, except for coming out every day to chat with Lin Qingwen and see the situation, they all stay in the Buddhist hall to copy scriptures.

  Lin Qingwan also started copying scriptures, but she only copied "The Sutra of the Bodhisattva Ksitigarbha's Fundamental Vows", which consisted of three volumes.

  Lin Yuhbin and Mrs. Xie thought that the extra scroll was meant for Lin's mother, Shang Shi.

  Lin Qingwan didn't make any explanations, she just silently copied an extra volume when she went back to her room.

  This time Lin Qingyan brought Lin Yuheng along not for managing household chores or accounting, but for the bamboo paper in the side courtyard.

  The first batch of bamboo has been soaked in the pool water for over a hundred days, and with the grass paper just made, Lin Qingyuan decided to start other processes today.

  Lin Qingwan didn't plan to let Lin Yuhong learn how to make paper, but just wanted her to see how bamboo paper was made. As she pounded and washed the soaked bamboo, she said: "The world is full of strange things, almost everything can be transformed, and different methods produce different results. What's more, objects can also be combined with each other. Who would have thought that fishing nets, tree bark, and rags could be processed and combined to make paper that can record words?"

  "In the past, people used tortoiseshell, bronze, bamboo slips and silk as carriers of words. Later, there was hemp paper, and slowly, paper became the carrier of civilization. The dark yellow hemp paper also turned into white Xuan paper, which can last for a hundred years without decay." Lin Qingwen handed the mallet to Cao Jin, instructing him to pound the bamboo thoroughly, washing away both the coarse shell and the green skin. "If people can make Xuan paper, they will naturally have other top-grade papers like it; it's just that people haven't made them yet."

  Lin Yuhong looked at the pool full of bamboo, it was hard to imagine that they could become as white and flawless as Xuan paper. "Can the bamboo paper made by Xiao Gu be comparable to Xuan paper?"

  Lin Qingwan smiled and nodded, "It won't be worse than this, just watch."

  "Is this also one of the reasons you want to make the formula for grass paper public?" Because there is a better, more attractive bamboo paper.

  "It can't be that we monopolize all the good things," Lin Qingwen pointed to herself and her, "The titles of Junzhu and Xianzhu on our bodies have some use, but for now they are not enough to completely protect us."

  Lin Yuhu tilted his head, "Why didn't that aunt tell Mrs. Xie? I think she's a bit worried."

  "It's because I don't want her to be in a difficult position," Lin Qingyan smiled and said: "Mother is of the Xie Yang clan, while I am now of the Lin clan."

  Lin Yuhong's mouth was slightly open.

  Lin Qingwan looked at her seriously and said, "Yuhin, not all honesty is good. Sometimes hiding the truth can be the best thing for each other. Mother also knows this in her heart."

  So, Mrs. Xie never inquired deeply about Lin Qingyuan's affairs, Zhuangzi's affairs, or the book office's affairs; even when she had people train the long workers and cultivate them into a private army, she pretended not to see it and wouldn't ask questions.

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

  This is good for each other.

  Even if one day Xie's family asks Mrs. Xie, she can still say with a clear conscience that she didn't know anything, because she really didn't know anything.

  Put the bamboo slips washed by Lin Qingyuan on one side, and Cao Jin and Meng Fu carefully applied the evenly mixed slaked lime water.

  The first batch of bamboo soaked is not many, but also not few.

  Three people worked together, with Lin Yuhbin helping out on the side, until late afternoon before all the bamboo was processed.

  Lin Qingwan then instructed Cao Jin and Meng Fu to put the processed bamboo into a specially made pot for simmering, with a method similar to boiling salt, covered with a wooden lid.

  Lin Qingwan patted her waist and stood up, saying: "Next is to watch the fire. I will assign a few useful servants to help you two. You will be divided into two shifts, day and night, guarding it. This time, we need to simmer for eight days and eight nights. During this period, the fire cannot be extinguished. After eight days, the bamboo can be taken out."

  Lin Qingwan then instructed Lin Yubin on the size of the fire and some precautions before taking him away.

  Bamboo paper is crucial for reviving Lin's bookstore and can even help the Lin family accumulate prestige, so Lin Qingwen cannot help but pay attention to it.

  Lin Yuhu also sensed his aunt's solemnity and couldn't help but pay more attention to the side house.

  Just as the bamboo rice was not yet cooked, something happened in another yard.

  Zhuang's household sent his youngest son back to report to Fang Dasong, "Fang Dabo, my father said that a large group of people are approaching from the east and southeast."

  On both sides were the city gate directions, where a large number of refugees gathered.

  "Fang Datong immediately said: 'Don't go to the tea house anymore, go home and bring your mother and sisters to another courtyard.'"

  He then turned to those beside him and said: "Let the second-in-command give the signal for all the people in the village to gather back and go on high alert."

  Then go find Yan Hu, "You take people to investigate, come back as soon as possible. If it's true, bring Yu Zhu back with you when you return."

  Yu Zhu was the one who stayed at the crossroads to look after the Qingfeng Teahouse. That kid had his right arm broken off, and his body was relatively weak. His wife had a big hemorrhage when she gave birth to their little daughter, so her body was never good afterwards. And they had many children at home.

  When the teahouse was completed, Fang Dasong and Lin Qingyu recommended their whole family.

  Lin Qingwan built the Clear Wind Tea House without any intention of making money, but rather to find stability in a chaotic world and gain some peace of mind.

  So Yu Zhu and his family's main task there was not to sell tea for business, but to guard the road.

  Apart from a few low hills, there is only one high mountain, Qingfeng Mountain. The Clear Wind Tea House has two floors, with the observation deck on the second floor. Standing on it and scanning around, you can see everything within five miles at a glance.

  Now it is winter, crops have been harvested, all things wither, and what can be seen is farther.

  Yan Hu and Fang Da Tong are both from the same humble origins, but Yan Hu's luck is better, with all four limbs intact. However, he had one ear cut off by the enemy army, which was slashed onto his face, leaving a very noticeable scar that looks quite frightening.

  When the soldier's face was injured but nothing serious happened, his ears were gone and he would have no future, so Yan Hu retired.

  However, his abilities did not decline, and his hearing had even improved. It would be best for him to go and investigate this time.

  Yan Huo received the order and immediately took two relatively well-trained long workers to sneak out.

  Fang Datong then went to report to Lin Qingyu, regardless of whether it was true or not, this matter had to be told to Lin Qingyu first, so that she could also make preparations.

  The people in the Zhuangzi quickly moved, the workers swiftly went to check the traps and weapons, and swiftly approached another courtyard.

  The farmers and tenants packed up their belongings and moved to another courtyard, leaving their homes for the long workers to use as a hiding place.
