Sent away Li Chengqian and Li Tai, Xuan Shijing returned to the study alone, in fact, it was too leisurely, so he wanted to find something to do for himself, since he wanted to improve the paper of the Tang Dynasty, then he first had to understand some papermaking technology, and now the craftsmen are at home for the New Year, and it is not good to directly find someone to come to the house to ask, so you can only look through the books yourself.

"Koji." Xuan Shijing shouted outside the study.

Koyoshi pushed the door in.

"What does the little marquis command?" Xiao Ji walked in front of Xuan Shijing and bowed.

"Long'er is still there with Erbao?" Xuan Shijing asked.

"Sister Long'er just brought Erbao to Dabao, and now she should be coming to the study." Xiao Ji replied: "Little Hou Ye has something to order?" ”

"It's not a big deal, by the way, Xiaoji, you go and find Uncle Zhong." Xuan Shijing commanded.

"Yes." Xiao Ji responded, and then exited the study.

Papermaking...... Xuan Shijing scratched his head and walked towards the room inside the study, where there were several shelves of books, and maybe he could find some information inside.

I walked into the back room and saw the books on the shelves, Xuan Shijing's head was two big, how could I find this!

The door to the study was pushed open, and Long'er walked in.

"Little Marquis." Long'er shouted softly.

"I'm in the back room, Long'er, you're here just in time, come, come in." Hyun Se-kyung tugged at his head and looked outside.

Long'er followed the sound and saw Xuan Shijing facing the books on the shelf, looking worried.

"Little Hou Ye, what are you looking for?"

"Didn't we say we were going to open a paper workshop, I'll look for books on this subject, Long'er, do you know what kind of books are written about these things?" Xuan Shijing looked at Long'er and asked.

Long'er pouted: "Where does Long'er know, didn't you say that you had seen any paper-making methods in ancient books?" ”

Xuan Shijing opened his mouth, but he didn't know what to say, he just casually found an excuse to prevaricate Long'er, but he didn't expect this girl to remember, she could only make up some more nonsense, and sure enough, telling a lie requires more lies to round it up.

"That was a long time ago, as for which book, I forgot, but I do know that this paper is a eunuch in the palace during the Eastern Han Dynasty, oh yes, Cai Lun, it was improved by Cai Lun, so the paper made at that time is also called Cai Hou paper, Long'er, do you know this?" Xuan Shijing told Long'er what he remembered about the paper.

Long'er shook her head and said, "This Long'er doesn't know, but the little marquis, since this Cai Lun is from the Eastern Han Dynasty and has improved the paper, it must be recorded in the book." Long'er tilted her head and thought for a while: "The Book of Han ...... during the Eastern Han Dynasty!" Little Hou Ye, it should be written in the "Book of Han". ”

"Okay, Long'er, you can help me find out the Book of Han, Master Hou, I'll squint for a while." Xuan Shijing said with a smile, and then looked at Long'er with a serious face: "This arduous and glorious task, Long'er, come on!" After speaking, he nodded to Long'er to show encouragement.

"Xiaohou...... "...... Long'er just wanted to say something, but Xuan Shijing quickly turned around and left, and went to sleep on the couch on the other side of the study.

Looking at Xuan Shijing's back, Long'er stood in place, chanting words in her mouth: "Didn't the little marquis say that he couldn't sleep during the day and at night......"

Xuan Shijing had just laid down when he suddenly bounced up again.

"I almost forgot, Uncle Zhong will come over in a while." Knocking on his head, Xuan Shijing walked to the front of the bookcase and sat down, taking advantage of this time to think carefully about the next papermaking matter.

The papermaking workshop does not have to be opened in Chang'an City, how expensive the land in Chang'an City is, if the improvement of paper can really be successful, it will definitely be bigger in the future, there is no suitable place in Chang'an City, so you can only find another place outside Chang'an City, and open the workshop, but it can not be too far away from Chang'an City, thinking about it, Xuan Shijing found that it would be convenient if he had a detailed map of Chang'an City, including the suburbs.

"Long'er!" Xuan Shijing shouted at the back room.

"Little Hou Ye, what's the matter?" There was some difficulty in Long'er's voice, as if she was carrying something.

"Put the Book of Han on the table first, and see if there is a map of Chang'an City and its suburbs in the library." Xuan Shijing said, this was originally the Qin Palace, and His Majesty Li Er often led troops to fight before he ascended the throne, the map or something, there should be storage in the library, it seems that there is a time for people to sort out this library, and it will be convenient to find things when the time comes.

"Oh, good." Long'er answered, and then there was a sound of rummaging through boxes and cabinets in the back room.

After a while, Long'er walked out, holding a roll of silk in her hand.

"Little Marquis, give, this is a detailed map of the vicinity of Chang'an, the latest, drawn in the eighth year of Wude." Long'er handed the silk in her hand to Xuan Shijing.

Xuan Shijing took the map, unfolded it on the bookcase, and after reading the map, his face showed joy, it was really a detailed map, this is a military map, all the terrain on it is clearly depicted, the fiefdom division of the nobles near Chang'an can be seen at a glance, and there is even the deployment of troops in the year.

"Long'er, I'll study this map, and you can continue to help me find the Book of Han." Xuan Shijing said: "It's hard work. ”

Long'er nodded helplessly, and then went back to the back room to help Xuan Shijing find the book.

Xuan Shijing carefully looked at the map on the bookcase, and began to search for a suitable place, the paper-making workshop should have a river nearby, easy to get water, and it must also be a sunny place...... Fingers swept over the area, there were still some scattered towns on the outskirts of Chang'an City, Xuan Shijing thought, when the time comes, the paper mill will definitely recruit workers, so it is best to be closer to the town.

A knock on the door came to Xuan Shijing's ears, and Xuan Shijing didn't raise his head, but just said please come in.

"Little Marquis, you look for me." Zhong Zishuo walked to the bookcase and bowed to Xuan Shijing.

"Uncle Zhong, come, sit, take a look at this map with me." Xuan Shijing beckoned Zhong Zishuo to sit down.

Zhong Zishuo knelt opposite Xuan Shijing, glanced at the map placed on the bookcase, and was shocked.

"Little Marquis, this is the battle map near Chang'an City, where did you find it?" Zhong Zishuo's tone was full of shock, this thing is unsightly to ordinary people, how could it fall into the hands of his own little marquis.

"What's the panic, Uncle Zhong, don't forget, this was originally the Qin Palace, it's not unusual to find such a map in the study, besides, this is a military map from several years ago, and it has long expired, come, Uncle Zhong help me take a look, let's choose a place near Chang'an, I'm going to build a workshop." Xuan Shijing pushed the map on the bookcase in front of Zhong Zishuo.

Zhong Zishuo looked at Xuan Shijing curiously: "What kind of workshop does Master Hou want to build, why do you still need to find a place outside Chang'an City?" ”

"The land outside Chang'an City is cheap, so the cost is low." Xuan Shijing said: "I'm going to build a paper-making workshop to improve the hard yellow paper we use now, first, Hou Ye and my ass will suffer less in the future, and second, make some money for Hou Fu." ”
