Xu Zhiyuan remembered that he still had a batch of familiar announcements here, which Lan Qing had thrown at him.

  Miss Lu is Lan Qing's life-saving benefactor, and with a few pieces of paper, she shouldn't mind.

  So, Xu Zhiyuan directly took out a large stack of familiar announcements.

  Cooked Xuan is coated with alum and so on during processing, so the paper is harder than raw Xuan, and the water absorption ability is weak, so that the ink and color will not be scattered when used. Therefore, the characteristics make Shu Xuan suitable for painting brush strokes rather than ink freehand paintings. The disadvantage is that there will be "leakage" or brittleness when stored for a long time. Cooked Xuan can be reprocessed, coral, mica paper, cold gold, wine gold, wax gold rib, peach tiger skin, etc. are all reprocessed by the cooked Xuan color paper.

  What Xu Zhiyuan gave to Lu Jiu was rice paper with wax and gold ribbed patterns.

  Lu Jiu touched the hardness, felt that it was okay, and he didn't pick any more, and said directly: "Lord Xu, please start." ”

  Xu Zhiyuan smiled slightly: "Okay, let's start reading it now, girl, please listen carefully." ”

  Lu Jiu spent a silver coin to buy ten pencils from the system mall, this thing can be made in ancient times, so Lu Jiu has no pressure to use it.

  Fortunately, the pencils in the system mall are all sharpened, and a pencil sharpener is also given.

  However, a fountain pen should be a bit simpler than a pencil.

  It's not a fountain pen, but the predecessor of the fountain pen, a quill invented in Europe, which is quite simple to make.

  Xu Zhiyuan's voice was very beautiful, and Lu Jiu listened carefully, like the most well-behaved student, with a focused expression and made a lot of notes.

  After talking for more than half an hour, Xu Zhiyuan stopped and took a sip of water, and found that Lu Jiu was writing with a strange-shaped thing.

  There were already several sheets of paper full of words on the desk.

  He picked up one and looked at it, and found that there were not only words, but also pictures, and some symbols that he couldn't understand.

  He didn't hold back his curiosity, and humbly asked: "Miss Lu, why are all the words you write missing half a piece?" ”

  Lu Jiu looked straightforward: "I don't have a good memory, I only remember half of it, anyway, I can know it." ”

  Xu Zhiyuan: I have never heard of "......", and I only remember half of it when I learn words.

  After a pause, Xu Zhiyuan continued to read the text.

  Lu Jiu continued to take notes, her words were not ugly, but they were still very beautiful, but Xu Zhiyuan didn't look very comfortable, just like going to the street to buy something, but he ran into a black-hearted shop, and he was short of two catties.

  At noon, Lu Jiu had lunch at the official media mansion.

  During the lunch break, Xu Zhiyuan looked at the strange-shaped pen in Lu Jiu's hand, and finally didn't hold back, and asked directly: "Miss Lu, what kind of pen are you using, forgive me for being clumsy, I really didn't recognize it." ”

  "It's a pencil." Lu Jiu explained to him briefly: "It's made of lead." ”

  In fact, the main ingredient of pencils is graphite, a black mineral found in England, which later became the painting material of Western paintings.

  But in ancient times, this graphite was not the same graphite, and ancient graphite and modern graphite were not the same thing at all, but there was graphite in ancient times, but it was often mistaken for lead.

  So Lu Jiu told him that it was lead, but he didn't want to explain too much.

  Xu Zhiyuan nodded as if he didn't understand: "So that's the case." ”

  "I still have a lot of special pens, I'll give you a few next time." Lu Jiu took out two pencils and stuffed them into Xu Zhiyuan's hand, and said very generously: "I gave it to you!" ”

  Rush duck!!

  Add more at noon, vote duck!!
