Qingcheng, don't be discouraged, this failure is the mother of success, as long as you continue to learn from experience, you can succeed, let me see this paper. ”

Ma Qiang stepped forward, picked up a piece of paper on the shelf, and tried to touch it.

Well... When toilet paper is enough.

"Then I'm probably going to have a difficult birth." Qingcheng sighed, Ma Qiang pointed out a clear direction before, Qingcheng as long as he continued to experiment, he would soon have results, but this papermaking, the speed of the test was slow, and Ma Qiang really just knew a general direction - it could be made, and it would be gone.

Only then did Qingcheng feel the difficulties of scientific research.

"Sir, this Prime Minister's Mansion is still a little smaller later, can you find a bigger place?" Zhang Ning's attitude towards Ma Qiang has changed a lot now, and there is more respect in his tone and less naughty.

Well, it seems that doing the questions is really helpful to regulate the physical and mental health of the child, and next time I still have to persuade Lin Zhi to learn to read, don't play crazy every day.

"I've asked people to build a paper research institute near Mashui on the edge of the city, and when it's finished, they can move there."

It is said that it is a research institute, but in fact it is a paper mill in the future.

"The color of this paper is quite white, and it is soft enough to be used as toilet paper, which can be regarded as commercial value." Ma Qiang tried hard to comfort.

Qingcheng looked at Ma Qiang with a resentful face, naturally dissatisfied with Ma Qiang's words of comfort.

"Don't look at me, I really don't know the ingenuity, I was in the master back then, I used paper directly, it all depends on you."

"It would be nice if there was a skilled craftsman who had experience in papermaking, by the way, I wrote this pencil for a day, and it is not very broken, sir, you can take a look."

Ma Qiang took the pencil and paper in Zhang Ning's hand, and while trying to write, he asked, "By the way, what about Sister Lime?" ”

After such a long period of slow recuperation, Lu Qingli's body has improved a lot, but according to Li Jue's words, Lu Qinglime is a congenital disease, which is difficult to cure and cannot be tired for a long time, so Ma Qiang threw the easier pencil project to Lu Qingling.

"Sister Lime said that she wanted to make the eraser that Mr. said, and she was still looking for materials." Zhang Ning replied with his head held high.

The eraser should be made of rubber, Ma Qiang actually does not have this material in his hand, but Ma Qiang has eucommia glue, which can be used.

In fact, it seems that the earliest eraser was bread... But using grain as an eraser, those poor students will probably eat while wiping it.

Although the pencil is not lead, but graphite, although it is not a toxic substance, Ma Qiang does not want his students to have ink in their stomachs...

"This pencil is good, it's ready for mass production, I'll go see the lime, the orange, or you can take a break."

The difficulty of making a pencil is much better than that of paper, basically two pieces of wood wrapping a piece of graphite, and the difficulty is only how to glue the wood chips and make the graphite powder bond without breaking easily.

Ma Qiang looked up and saw that the green orange hair was messy, and he was a little distressed.

A skilled craftsman who can make paper... Ma Qiang also looked for it, but because it was a papermaking technique that the palace had renovated, the paper that could be used now was produced in Luoyang, and Ma Qiang did not have the ability to dig Liu Hong's corner.

Although Ma Qiang felt that as long as the price was right, Liu Hong would not care.

Well, let's send someone to look for it, in case we can find it.

- Chang'an

Chang'an, the center of the former Han Dynasty, has lost its former glory since Wang Mang usurped the Han Dynasty.

It can be seen from the population account book that in 2 AD, on the eve of Wang Mang's usurpation of the Han Dynasty, Guangjing Zhaoyin had a population of 680,000, while the other two counties of Guanzhong, Zuo Fengyi and Right Fufeng, had a total population of 1.76 million, and the total population of the three counties was more than 2.4 million.

In 140 AD, after more than 100 years of recuperation after Wang Mang's usurpation of the Han Dynasty, the population of these three counties was Jing Zhaoyin: 290,000, Zuo Fengyi: 140,000, and Right Fufeng: 90,000, with a total of only more than 500,000, which can be described as a small pitiful.

And the next series of Qiang Rebellion wars, so that after the Yellow Turban Rebellion, the total population of these three counties is only more than 400,000 people, it is fertile for thousands of miles, inhuman, the huge Chang'an City, only less than 60,000 people, compared with Luoyang City, which is known as a million, it is really pitiful.

But at this moment, because of the rebellion in Liangzhou, Chang'an ushered in a rare highlight moment.

Countless scholars and people who fled from Liangzhou gathered in Chang'an, waiting for the moment to return to their homeland.

Among them, there is a pair of brothers who are guests in Huangfu Song's mansion.

Huangfu Song, as the commander-in-chief, is basically in the barracks, and this mansion has become a place for the two brothers to greet friends.

"Brother Boying! Brother Wenshu can be here? ”

The two gentlemen walked in the mansion, shouting loudly.

"Good word!"

With a cheer, the two found their goal.

In a garden, four or five Confucian scholars were gathered around to watch a man write, who had gray hair, was dressed plainly, and had a large pen in his hand dancing like a dragon and snake.

The two glanced at each other, walked over, and when they saw the word, they couldn't help but applaud.

I saw the posture of the word, made of one stroke, occasionally not connected, and the blood is continuous, and its connection, the qi veins are interlaced, but it is the best cursive handwriting.

"Good!"

As the man's pen was retracted, everyone couldn't help but cheer in unison.

"Bo Ying's words are now the best in the world!" A scholar said with a sigh.

"Wen Shu's words are not inferior to mine, only my third brother Shuwei, who inherited my father's art of war, is not good at this." The man looked up at the two people who had just come in, and said happily, "Brother Ziyi, Brother Daya, why did you come to Chang'an?" ”

"You Zhang Zhi came, can't we come, your brother has arrived in Chang'an, I don't know how many scholars are coming to pay homage to the two sages of cursive today."

"Hey, your Uncle Zuo and Daya are also enough to become a family, I see that the two of you are too famous in Luoyang, come to me to hide quietly."

Everyone immediately burst out laughing, and many people sighed, they didn't expect that this small mansion actually gathered four calligraphy masters.

It turns out that these four people, are today's calligraphy benchmark figures, just wrote is Zhang Zhi, one of the three Ming in the West Liang Zhang Huan's eldest son, he and the second brother Zhang Chang are proficient in cursive, in order to practice cursive, to silk as paper, Linchi to learn books, leaving a good story of the ink pool, these two brothers were also known as "grass saint" and "sub saint" by later generations.

Zhang Yang was originally a native of Dunhuang County, after his later years, he taught in seclusion in Hongnong, died of illness four years ago, and the three of their brothers did not become officials, and returned to Dunhuang with Zhang Yang's bones, although the three of them were not as proficient in military affairs as Zhang Yang, but they also understood the situation in Liangzhou very well, knowing that the rebellion would not be so simple to be quelled, so they moved their family to Chang'an, ready to avoid the edge, and then find a way to return to their hometown after Liangzhou was pacified.

And Zuo Bo Zuo Ziyi and Mao Hong Mao Daya are both top students of Hongdu College, proficient in eight points, although they are not as high as the achievements of the Zhang brothers, but they are also leaders for a while.
