Chapter 133: The Picture.


    Kim Ki-woo had always favored schrs and emphasized the importance of reading countless times.


    Thanks to him, reading had be a universal daily activity for the imperial citizens long ago.


    Even if their upation was something like a farmer or a miner, which had nothing to do with academics, the imperial citizens had a deep-rooted perception that they should read books to some extent.


    Of course, the amount of books each individual read varied greatly.


    Warm Hat was beyond just reading a lot, he was addicted to print.


    He read books from the moment he woke up until he went to bed.


    He even got a job as a librarian at the Imperial University Central Library, which had a highpetition rate, in order to do so.


    Theres no book thats not here. Im happy


    This library boasted thergest scale in the empire.


    It was more so because the Imperial University was the center of academics.


    Warm Hat collected and devoured a tremendous amount of knowledge by reading all kinds of books avable in the library.


    Excuse me, librarian. Can I ask you something?


    Of course. Ill answer if I know it.


    He had read so many books that his breadth of knowledge was very wide, so much so that even the schrs of the Imperial University came to him for advice.


    Why are you still in the library with such talent? You can easily get into the Imperial University.


    Haha. If I be a schr, I wont have much time to read books. Im satisfied with my current life.


    Tsk! Youre a weirdo. Let me know if you change your mind.


    Thank you for your interest.


    Many department heads from various fields came to him and rmended him to enter the Imperial University, but he refused them tly.


    He just generously shared his knowledge with the schrs who came to him.


    Thanks to that, he became a famous attraction of the Imperial University Central Library.


    Then one day.


    Leonardo da Vinci


    Warm Hat was deeply interested in a book that came from a region called Europe in the east.


    The book contained various physical hypotheses and experiments that he had researched.


    Amazing, right? Is he a genius?


    Of course, most of them were already verified by the imperial schrs, but he was curious about how he achieved such academic results by himself.


    So Warm Hat started looking for information about this person named Leonardo da Vinci.


    Fortunately, he was a celebrity, so books rted to him were easily found.


    Warm Hat gathered them and read them one by one.


    And he was greatly surprised soon after.


    He researched all this by himself?


    He left achievements in various fields, and they were all very outstanding.


    Wow If he had been born in the empire, maybe he could have made history.


    It was really regrettable that he died just a few decades ago.


    Warm Hat put aside his regret and read everything that Leonardo da Vinci had left behind.


    In the process.


    Camera obscura?


    Warm Hat was fascinated by Leonardo da Vincis Codex Anticus.


    Camera obscura was a term that referred to the phenomenon of externalndscapes or shapes being projected upside down on the opposite wall through a small hole in one side of a dark room or box.


    This was a topic that had been researched by ancient Chinese Mozi or ancient Greek Aristotle long ago, but Leonardo da Vinci applied it to art.


    He made a camera obscura as a tool for drawing pictures in detail.


    Warm Hat thought of his old friend, Steep Cliff, as he saw this.


    He would love it if I told him.


    He had only read the contents of the book so far, so he wasnt sure if this was true, but he thought his friend who was struggling to find his own style would like it.


    And this expectation hit the mark.


    After telling Steep Cliff about the principle of camera obscura, not long after, he ran to the central library and hugged Warm Hat tightly.


    Such a groundbreaking method You are truly amazing. Haha! Thank you so much!


    Why are you being so gross? Anyway, its all thanks to the camera obscura, right?


    Yeah, thats right. Come to my studio when you have time. Ill show you the real thing.


    Really? Then Ill visit you after work today.


    Warm Hat was curious about how the camera obscura actually worked, so he readily epted his offer.


    And as promised, he went to the studio on the steep cliff after work.


    Is this it?


    Youre here? Come and see for yourself.


    He followed his friends guidance and checked the actual operation of the camera obscura.


    Wow. This is amazing. It really shows upside down because of that tiny hole?


    Thats what Im saying. Isnt this the mystery of science?


    Talking about science when youre an artist.


    What did you say?


    They bickered with each other, but a smile soon bloomed on their lips.


    After finishing all the tours, Warm Hat repeated to himself on his way home.


    This world is really mysterious.


    Thanks to that, he devoured more books containing various information from the central library.


    ***


    For Warm Hat, the camera obscura was nothing more than a happening.


    He was exposed to so much information every day that he soon forgot about the camera obscura.


    But a big turning point in his life happened.


    It all started from a book.


    Photosensitivity


    It was a book containing the research of a famous chemist from the Imperial University.


    He studied materials that changed by light, and he called these materials photosensitive materials.


    Among them, he described in detail the photosensitive materials that hadrge changes in this book.


    There were many technical terms here and there, but Warm Hat had no difficulty in understanding them because he had read countless books rted to chemistry.


    Its amazing how light works. There are materials that change like this just by shining on them


    As he was thinking, he remembered the camera obscura he saw at the studio on the steep cliff and its principle.


    Come to think of it, the camera obscura projected an image on the wall.


    The steep cliff had established his own style of painting thanks to the camera obscura, and hisst exhibition caused a great sensation in the art world.


    That was also an example of applying light to real life.


    He was able to draw realistically by tracing the projected image.


    Wait a minute.


    sh!


    At that moment.


    In Warm Hats head, two separate phenomena merged into one in an instant.


    Camera obscura and photosensitivity?


    The former was a device that projected an image on the opposite wall through a small hole.


    And thetter was the property of materials changing by light itself.


    If there is an image projected, there is a difference in light in each part If I shine an image on a highly photosensitive material, wont there be a difference in each part of the material?


    As these two phenomena werebined, Warm Hat thought of this.


    But he soon shook his head.


    What am I thinking? Im not a chemist.


    No matter how many chemistry books he read, he was not a chemist from the Imperial University.


    And the experiment above was something that chemists would do.


    So he brushed off his thoughts and started reading another book.


    But even as time passed, Warm Hat couldnt get rid of his hypothesis from his head and kept thinking about it from time to time.


    It seems possible.


    If the image of the camera obscura is drawn by photosensitive material as he thought


    This was surely an amazing discovery.


    Phew Well, let me try to exin my idea.


    Fortunately, several schrs in the Imperial Universitys chemistry department knew about it, and the department head was one of them.


    Warm Hat decided to act on his impulse and went to see them.


    He didnt want to bother them after work, so he approached the chief librarian of the central library and asked,


    Excuse me, may I go to the chemistry department for a while?


    Did the chemists call you or something?


    No, but I have something to ask the department head.


    Ha ha. Did you get stuck on something while reading the chemistry books?


    Yes, well


    He did get stuck, so Warm Hat nodded his head.


    Alright. Well take care of the rest, so you can leave for today.


    Ille back after I finish.


    No, you dont have to. Youve been living in the library without taking any days off. Even giving up your holidays. You should go out and have some fun.


    Thank you for your concern. Then Ill be going.


    ***


    After that, Warm Hat ran to the chemistry department.


    When he arrived, a schr who was walking by recognized him.


    Huh? What are you doing here? What about the central library?


    Hic, huff


    He caught his breath for a moment and asked him.


    Can I see the department head for a moment?


    The department head? Hmm I dont know what it is, but follow me.


    Thank you very much.


    Luckily, the schr kindly guided Warm Hat to the department heads office.


    Soon they arrived at the office.


    Huh? What brings you here all of a sudden?


    He said he wanted to see the department head.


    The department head? Who are you?


    You know him. The famous librarian from the central library.


    Oh Youre him. Well, let me talk to him for a moment.


    The schr didnt hesitate and knocked on the office door.


    Department head. Iming in.


    Sure,e in.


    A deep voice echoed from the other side of the door, and the schr opened it.


    He came to see you.


    Hmm? Arent you Warm Hat? Ha ha! Whats up?


    Ha ha. Well


    Dont just stand there,e in.


    The chemistry department head, Wide Pot Lid, gestured to Warm Hat.


    Then excuse me.


    As soon as he sat down on a soft sofa, Wide Pot Lids words continued.


    So, did you finally decide to apply to the Imperial Universitys chemistry department?


    Thank you for your offer, but I dont have that intention yet.


    Aww, too bad. Someone like you should shine in the chemistry department.


    Arent there many schrs who are iparable to me in the chemistry department?


    Pfft. These days there are too many idiots Sigh.


    Warm Hats expression became awkward at that remark.


    The chemistry department was one of the very core departments in the Imperial University.


    Thats why the admission rate of the Imperial University was already murderous, but it was even more so for the chemistry department.


    It meant that there were many talented people who flocked there.


    But Warm Hat couldnt understand why he said that.


    So, whats the real reason you came to see me at this hour? Youre not someone who goes out of the library often.


    Oh! Thats


    He handed over two books he brought from the central library to Wide Pot Lid.


    This is a research book on photosensitive materials. And this is


    Its about camera obscura.


    Camera obscura?


    Wide Pot Lid flipped through the pages and quickly skimmed through the contents.


    Thanks to Warm Hats exnations along the way, it didnt take long for him to grasp the principle of camera obscura.


    After closing the book, he crossed his arms and asked.


    What are you curious about here that made youe all this way?


    Its not so much curiosity as I wanted to ask for your advice on whether my idea is feasible or not.


    Advice Alright. Let me hear it.


    After getting permission from the department head, Warm Hats hypothesis began to spill out of his mouth.
