It was late at night, Liu Ao was still in the study, and the candlelight was on......

Aunt Wang came to see it nervously several times, and the young master seemed to be pondering, and had been sitting there for two hours. Before dinner, Xiao Nan and Xiao Wu said that their brother was thinking about a problem and had something to do with a person named "Cai Lun", because there was a piece of paper on the table with the word "Cai Lun" written on it!

Who is "Cai Lun"? Could it be a beautiful little lady? Today, the young master has taken a fancy to it? Shocked to think about it when you come back? Old Li Gang looked at Liu Ao's appearance, it seemed very strange, because Li Gang also went in, Liu Ao, who usually greeted him quickly, as if he didn't see it, Li Gang hurriedly and gently left again.

Instructed anyone not to disturb Liu Ao, saying that Liu Ao had entered the realm of enlightenment. The realm of enlightenment is the realm of Taoist legends, and Lao Li Gang is very envious.

In fact, Liu Ao knows who comes in. I just don't want to move. This is also a habit brought by later generations, I haven't thought about a deep question for a long time, and today I suddenly think of a question. That is, papermaking was invented by Cai Lun, a eunuch in the Eastern Han Dynasty, why is the paper of today's Tang Dynasty still dyed yellow paper and hard yellow paper coated with broad wax? It's been hundreds of years, and there hasn't been much progress?

Didn't you say that the rice paper of the Tang Dynasty had already appeared? I haven't thought about this question all the time, and today I suddenly popped up. On the way back, Liu Ao asked Uncle Dumb a question: "Uncle Dumb, have you ever seen pure white paper?" ”

"Yes, exquisite white silk, many painters still use it today, it is too expensive, only extremely valuable paintings, or precious documents, use white silk."

Uncle Dumb's words prove that white paper has not yet appeared. I returned to the study and read the old master's manuscript step by step. There is also white silk, and there is also paper. The repaired part is silk.

Liu Ao doesn't remember when he read a passage: Cai Lun's apprentice Kong Dan, who was engaged in papermaking in southern Anhui, had always wanted to make a particularly ideal white paper to use for his master to paint and revise scores.

But after many trials, it didn't work out. Once, in the mountains, he happened to see some sandalwood trees lying next to the mountain stream, which had been eroded by the water and rotted and turned white because of the age. Later, he used this bark to make paper, and finally succeeded.

Other words. Sandalwood bark can be used to make rice paper! Sandalwood, hehe. Nowadays, it is one of the main tree species all over the mountain. So, this Cai Lun's apprentice Kong Dan didn't pass down the method of this paper? Cheap me, haha......

Liu Ao's laughter came from the study...... It's just like a duck barking no matter how you hear it.

The voice change period is not over yet! The first person to go to Liu Ao's study was not Aunt Wang, but Lao Li Gang.

It turned out that Lao Li Gang decided that Liu Ao had entered the realm of Taoist enlightenment, so he kept guarding, at the door, no one was allowed to enter, not even the carbon furnace sent by the housekeeper, for fear that the smell of the carbon furnace would disturb Liu Ao's realm.

Hearing the laughter inside, he hurried in: "What did you realize?" The voice was very excited.

"What realizes what? It's so cold, butler, why don't you get me some charcoal basins! Why is it all spring, and it's still so cold? Liu Ao didn't pay attention just now, only to find that it was already late at night.

Liu Ao didn't come out of the study, how could the housekeeper sleep? Hurry over and put the charcoal basin on the table, one is afraid that it will not be enough, so I will bring another one. Aunt Wang hurriedly brought the meal that was still hot to the young master.

"Grandpa Li hasn't slept yet, you sit down first, I'll eat something, I'm so hungry!" Give a charcoal basin to Li Gang, put one on the side of the coffee table, and eat it by yourself.

According to the young master's habit, the housekeeper Zhou Yan made a pot of tea for Li Gang and withdrew. Knowing that two people have something to talk about.

"Grandpa Li, do you want to use those very white, very white, thin as cicada wings? And it's very delicate! Liu Ao finally had his fill, pulled the teapot, gave himself two cups in one go, and then said to Li Gang mysteriously.

"How can there be such a good paper, I'm asking you, what did you just realize?"

"Just now? That's it, make the surface of this paper white, twice as thin, no, twice as thin. It's stronger than this, you look at this paper, it's not tough! As he spoke, he gently tore the paper with Cai Lun written on the table in half, and there was no broken pulp or stalk in it.

"You didn't move for more than two hours before you realized this thing?" Li Gang was very disappointed, thinking that Liu Ao would be able to realize some immortal methods or something. In ancient times, people's belief in gods and goddesses reached the point of obsession. Li Gang is no exception.

The gods are inviolable, so ingrained in people's minds that they are hard to shake. Therefore, whether it is the Buddha of Buddhism or the Sanqing of Taoism, it is very popular.

In today's situation where the people generally do not have enough to eat, the monks are all plush and very Buddha-like. The Taoist priests are all extraordinary. A faction of fairy wind bones.

People would rather go hungry themselves, and they will also save a few copper coins from their mouths and reverently put them into the merit box in the temple to make sesame oil money. Or dedicate it to the Taoist temple and ask the Taoist priest to come and do a ritual for his family.

Anyway, nowadays, monks and Taoist priests seem to be very inseparable. The main believers of the monks are the common people. The main believers of the Taoist priests are the Shi clan. Or, both.

However, in the end, it was a great Confucian, and he was quickly attracted by the paper described by Liu Ao, after all, he was a literati, and his love for paper was not understandable by ordinary martial artists and ordinary people.

"Really?"

Liu Ao nodded.

"How long?" It's a few months faster, half a year to a year slower, after all, you have to experiment. ”

"Well, then get it, the old man still has some copper coins, and I will bring them to you, anyway, my two children are no longer there, and I only have one grandson, who is serving in the court, and when the time comes, take care of one or two more." It's late, let's rest. After speaking, I got up, and I was a little excited!

"I'll help you." Liu Ao went to help Li Gang. Zhou Yan came in from outside. "The young master is going to rest, and I'll send the old gentleman."

As he spoke, he helped the old gentleman and left Liu Ao's study. "Wait a while, you and Uncle Ma will come over for a while."

"En......"

Now, the Liang family has hated themselves, and they have to make some preparations, otherwise they will suffer.

can come together with the Xingyang Zheng family of the wang family, it can be seen that the Liang family still has some heritage, otherwise they have interests in business, and the relationship is not small!

Remember, the Liang family and the Dou family still have some relationship, but the relationship is not deep, it seems that this Liang family is making friends with these Shi people everywhere! Marriage, interests, hehe, everything!

Commercially, it's paper! It's not difficult, but the hard thing is that I don't have a place to get it now! Papermaking is dirty, especially the wastewater. Liu Ao didn't want to dirty his yard. Although this old mansion is not its own.

recalled Liang Yuanwai's last words: "My house, what do I want to repair?" ”

Liu Ao read a commercial war in later generations, talking about real estate, in order to squeeze away a real estate developer, the land was going to build a high-end residential community, and he was building a public toilet next to it. Get a garbage dump. In the end, they squeezed people away and gave up the fast land. It has also become a classic story of Shang Zhan, and I can't remember which book I read.

So what can this Liang family repair? Can you disgust yourself? Digging stinky puddles? Mud, it can't be a manure tank, right? I'm really sick to death that way.

Not long after, Zhou Yan took Ma Han to the study. "Remember the Liang family who insulted Xiaobei's mother?"

Both of them nodded, and the housekeeper Zhou Yan knew even more, because he was still the Liang family's account keeper at that time.

"In the near future, he may have to give us some trouble. Don't know yet, right? The mansion built by our family is next to the homestead of the Liang family. He said that the construction of our family's mansion broke his family's feng shui, and I met him today. ”

"This gou-day, he won't do good things, he dares, now in our family, you look at those young masters, just pull out one and scare him to death. Unless he's in the wrong head! Now Mahan is also speaking in a big way.

"If you know the inside story, you definitely don't dare, I'm afraid he won't know, if you really build a manure tank next to our house, won't you disgust us? So, we're either going to do nothing or we're going to do nothing.

If we don't do it, if he really wants to get into trouble. The main thing is to take revenge on me for that crooked three, then I will kill him and completely destroy him from his family's business. Even if we don't retaliate against him, I have to do the improvement of this paper, I have already told Grandpa Li just now, and it is not aimed at him for the time being.

Find someone to understand the connection between him and several clans, and the relationship of interests. Tomorrow, Uncle Zhou will go to Chu Chu's mansion and ask Chu Chu to help me check it. Uncle Ma, take care of some more people and buy the bark of the sandalwood tree......"
