After entering Xudu City, Dianman sent Cao Pi back to the mansion and immediately went to Sikong Mansion to inquire about the news, and Cao Pi returned to his courtyard and told Hui'er to count the houses that could be inhabited in the courtyard, and let him choose when he came back. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The so-called partial house, naturally biased, is the house on both sides of the courtyard, Cao Pi three into the courtyard, there are naturally a lot of partial houses, except for some used to put some sundries, most of them are vacant, and there is no problem with living one more person.

After explaining Hui'er, Cao Pi took Shu'er to his study, took out a brush and inkstone, and then took out a few Zuo Bo papers and put them on the table.

During the Han Dynasty, an important period of the development of Chinese writing, the formation of official script, and the evolution of cursive script were all in this period of the Han Dynasty, Cao Pi's memory, there are two very famous calligraphers in contemporary times, one is called Cai Yong, for this person, Cao Pi is more familiar with his daughter Cai Wen Jiyan; The other is from the Zhong family of the four major families of Yingchuan, and the elder brother of Zhong Yan, the head of the Zhong family, Zhong Yuanchang.

Cai Yong is famous for flying white books, and Zhong Miao is famous for being proficient in seals, subordinates, truths, lines, and cursive calligraphy, but Cao Pi knows that in later generations, Zhong Yong's calligraphy achievements are much higher than Cai Yong, and he is known as the originator of regular calligraphy.

What made all this is what Cao Pi saw in front of him, pen, ink, paper, inkstone, and the four treasures of the study, and now this thing is not something that everyone can afford, for example, the young man in the rice shop in Xu Du still uses a knife, pen and bamboo slips. Most of the brushes in this year were made of the hair on the back of rabbits, and the head of the pen was about the length of a Chinese ruler. We call this kind of pen rabbit pen, which is characterized by strong hardness, smooth inking, is the best pen material today, but this kind of pen is not durable, easy to be bald, it is estimated that it can write a thousand words (referring to the traditional Chinese characters of the Han Dynasty). Now it's an absolute luxury. As the name suggests, there are only three of these pens.

Now the paper is not more than 90 years ago Cai Lun made Cai Hou paper, Cai Hou paper that quality is thousands of miles worse than straw paper, to put it bluntly is to break the bonded plant fiber piece, the current paper is just emerging Zuo Bo paper, Sabo is the name of the person, the word Ziyi, the age is seven or eight years younger than Cao Pi's father Cao Cao, is a big celebrity, the reason, is because he is good at papermaking, his paper abandons all the miscellaneous materials of Cai Hou paper, mainly with some hemp products, such as sacks, hemp rope, Bast shoes are made in a certain proportion with mulberry bark. This kind of paper has toughness, moisture resistance, not soaked in ink, very conducive to writing, to the end of the Qing Dynasty still has people to use, but the process is very complicated, and the hemp fabric also includes linen clothes, now the war is in chaos, many people are not even clothed, two or three sets of clothes a year, who will take this kind of life with things to make paper? So although the Zuo Bo paper is good, but the cost is extremely high, expensive to death, Cao Pi's Zuo Bo paper from the age of six to start to receive, every month can only get three from Cao Cao, now in front of him Zuo Bo paper a total of seventy-two, indicating that Cao Pi has not used this paper for two years, it can be seen how much cherished.

As for the ink, it comes from the inkstone, this inkstone is now generally a stone inkstone, in fact, the stone in the mountain can become a stone inkstone with a little build, China has a lot of resources, and there are many stones that can make stone inkstone, which is not a rare thing, so some people want to write some flying white book or official book or something, they will use locust branches or bamboo to beat a piece into a filament, bundle it together, grind the ink with the inkstone, and write the words on the bamboo slip in the ink, without a rabbit pen or Zuobo paper, so that you can save a lot of money.

But now, Cao Pi has put all these precious things on the table, if nothing else, just to prepare for changing the world, and he plans to write a practical plan for hybrid rice.

You must know that although hybrid rice does not take much time, the process is more complicated, for example, the three-line hybrid rice that Cao Pi is now preparing to cultivate needs to cultivate three samples, one is the male sterility line, the other is the male sterility maintenance line, and the male sterility recovery line. The cultivation of these three samples alone is three long treatises.

At this time, Shu'er was grinding ink on the side, and Cao Pi began to write hard, and before Cao Pi could write a few words, Shu'er's curved moon eyebrows wrinkled, and she couldn't help asking, "Is Childe writing?" ”

"yes!"

"Really?" Shu'er's brows are even more twisted, her elementary school singing and dancing, poetry, although it can't be said that it is a study of the past and the present, but the words must be recognized, but now the words written by her son on the paper, she can only recognize one out of ten words, and in some places she can't even recognize one of the twenty words, and some words are plausible, I don't know if it is the word in her memory.

Of course, Shu'er doesn't know a few words, Cao Pi is now writing simplified characters, for two reasons, first, although he now knows how to write Han Dynasty characters in his mind, but there are too many strokes, and his paper and pen are limited, especially pens, so he can only write simplified characters for later generations, which can save resources. Second, this hybrid rice technology in the future should definitely be the achievement of winning the Nobel Prize, if he writes the words here people can understand, maybe he will plagiarize his technology, although it is now 197 AD, but Cao Pi always believes that smart people will have which dynasty and which generation, maybe give them a fulcrum they can pry the world, this is Cao Pi's stunt, naturally to use a bit of secrecy.

Most of the characters of the Han Dynasty and the simplified characters of later generations are not the same, only a few words are in the same situation, Shu'er naturally can't understand it, but she is a maidservant, and she will not ask if she reads the son's hard work, and she will naturally not ask questions, and it is very rude to disturb the son.

"Rice is a self-pollinated plant, the female and male flowers are grown on a plant, to put it bluntly, it is to complete the process of flowering and fruiting by itself, and the three lines are to integrate the excellent genes of different rice plants...."

"Three-line hybrid rice supporting steps: 1. Artificial production of male sterile lines: that is, the development of pistils is normal, and the development of stamens is degraded or aborted, and can not be self-pollinated and fruited, and the dominant plants of this line are selected to maintain excellent genes; Second, select male sterile maintenance line plants. That is, the plants with normal development of female stamens are selected, and their pollen is awarded to the pistils of the male sterile line, which can not only form pairs of seeds, but also obtain the characteristics of male sterile plants after sowing, but also inherit the sterility characteristics of the male sterile line, which is to cultivate male sterility restorer line plants for the male sterility maintenance line (3). Its pollen is granted to the pistil of the sterile line, and the resulting seed is sown and the grown plant regains its fertility, which is the restorer plant..... The seeds produced by the restorer line have the dominant genes of the sterile line and the maintainer line, so they can be planted in a large area, and of course, they can also be cross-cultivated with the male sterility maintainer line plants again to optimize the gene ....."

In the study, Cao Pi's pen was flying, and Shu'er, who was grinding ink, was looking at the strange font on Zuobo's paper with a puzzled face while grinding ink.
