After visiting the Bronze-Bone and Golden-Leaf Tree, Qi Tongchen took Zhu Changyang and his party to the guest room to stay.
Zhu Changyang hesitated for a long time, but finally mustered up the courage to ask, "Brother Qi, does your sect have any courses that I can audit?"
Qi Tongchen was confused: "What do you mean by listening in?"
"Even outsiders can listen." Zhu Changyang explained briefly.
"Brothers, do you want to take classes in our sect?" Qi Tongchen understood and said, "That's fine, but they are all low-level courses, I'm afraid you are not interested."
There is also communication and cooperation between the sects in the world of cultivation. Disciples often compete with each other, and every ten years there are competitions between sects.
As Zhu Changyang mentioned, there are also forms of "auditing", but they are very rare. Because the courses open to "auditing" are mostly simple techniques, after all, no sect would be generous enough to teach its unique secret techniques to the public, so as long as there is a sect, the monks will not go to other sects to attend such courses.
Zhu Changyang, a self-taught player, was very interested: "No, no, no, I want to listen."
Qi Tongchen was a little surprised, but still nodded: "Okay, let me tell Master."
That evening, Qi Tongchen brought Zhu Changyang three plaques, which were wooden plaques approved by Sikoulot to allow him to enter and leave the classroom temporarily. He also gave Zhu Changyang a class schedule, which was the course schedule for low-level disciples of the Jijin Sect in the next few days.
Zhu Changyang thanked him again and again, and after seeing Qi Tongchen off, he called Jun Shu and Jie Li out, handed each of them a wooden sign, and said, "Let's go to class together tomorrow."
Jie Li never thought that he would have the opportunity to attend classes in the weapon refining sect in his lifetime. He nodded happily: "Thank you, Master."
Jun Shu frowned slightly and asked in confusion: "Aren't we here to have fun? Why do we still have to go to class?"
"It's okay if you don't want to go to class." Zhu Changyang readily took the wooden sign back and said, "Then let's give the opportunity to the developer. Let us developers be a cultured cat."
The developer's cat eyes widened: "Meow?!"
"No." Jun Shu immediately snatched the wooden sign away, "This is mine. I want to sleep in class."
Zhu Changyang: “…”
You should be more restrained when you are on other people's territory!
.
The next morning, Zhu Changyang went to the classroom with his two tails.
The Ji Jin Sect was quite kind and did not really arrange those lowest-level preschool courses for him. Instead, it let him take classes with a group of disciples who had already established their foundation.
These students had received news in advance and knew that Zhu Changyang, who had recently become famous, would come to audit the class. Therefore, they were not surprised to see Zhu Changyang and the other two. Instead, many of them came up to greet them enthusiastically.
"I never thought I would have the opportunity to take classes with Master Zhu. It's such an honor." One of them said, "Yesterday I had the opportunity to see the rice cooker you made. It's really a rare thing."
It turned out that after Qi Tongchen left yesterday, he called all his fellow junior brothers and sisters together, and used the electric rice cooker given by Zhu Changyang to demonstrate in person how to easily cook a pot of fragrant rice without firewood or supervision.
The disciples were amazed and had a great impression of the leaders. Some did not agree, but due to etiquette, they would not make themselves look bad.
Zhu Changyang was now immune to this kind of praise and exchanged a few words with everyone calmly.
After a while, someone said, "Elder Cen is here."
Elder Cen was one of the elders in charge of teaching in the sect. Upon hearing Elder Cen's arrival, everyone returned to their seats.
Zhu Changyang sat down at the last empty table with his little tail, then took out three small metal sticks from his pocket and gave one to Jun Shu and Jie Li respectively: "Here, take it."
Jun Shu was confused: "What is this?"
This metal stick is about the size of a little finger, half a foot long, with a pointed end and the other end seemingly movable. It looks a bit like a pen, but it is clearly not a pen.
Studio:
[Wow, a mechanical pencil!]
[Is this a true academic master? He can even make his own stationery! ]
"This is a mechanical pencil." Zhu Changyang said as he pressed the movable end, and the pointed end immediately spit out a thin piece of lead.
He then took out three more notebooks and gave one to each of the other two. He then wrote on the remaining notebooks with a pencil, "This way you can write. It's more convenient for taking notes."
After traveling through time for so long, he barely adapted to traditional Chinese characters, but he still couldn't get used to writing with a brush.
The artistic quality of soft brush calligraphy is beyond doubt, and many famous calligraphy works are priceless treasures. But in terms of convenience, the brush is far inferior to the hard pen.
Taking notes in class requires speed, so after getting the class schedule, Zhu Changyang made a mechanical pencil and notebook overnight.
The structure of a mechanical pencil is not complicated, it can be made of metal. The lead is made of graphite, clay and auxiliary materials such as gum.
Jun suddenly saw Zhu Changyang writing small words on the paper. He exclaimed "Huh", followed suit, pressed out a piece of lead, and then drew a line on the paper.
Then the lead broke.
Jun Shu paused and said, "...?"
"Don't hold it like this." Zhu Changyang laughed. Jun Shu was still using the gesture of holding a brush, so the focus was naturally wrong.
Then he reached out and grabbed Jun Shu's fingers to readjust their positions, "Hold it like this, be gentle when writing, don't use too much force."
Jun Shu felt Zhu Changyang holding his fingers. His fingertips were very soft, and the touch was strange. His heart was inexplicably moved, but unfortunately it was fleeting.
"Master, is this how we hold it?" Jie Li asked. He had a keen eye for observation. After watching Zhu Changyang adjust the position for Jun Shu, he learned most of it himself.
"It's almost there. You can hold it a little lower." Zhu Changyang reached out his hand to adjust it for him, but when he was halfway there, another hand suddenly reached out from the side and stopped him.
Jun suddenly glanced at Li Li and said righteously: "Let him learn by himself. If he needs to be taught step by step for such a small thing, how will he learn other things in the future?"
Jie Li thought it made sense and nodded firmly: "Yes, I can do it myself."
There is no need to raise it to this level. Zhu Changyang complained in his heart, but still took his hand back: "Okay."
Then Jun Shu extended his hand: "You can continue to teach me."
Zhu Changyang:
Just as he was speechless, a disciple of the Jijin Sect next to him finally couldn't help but lean over and ask, "Brothers, this pen seems very interesting, can I take a look at it?"
"Of course." Zhu Changyang smiled and took out a few more from his pocket and handed them to him, "If you don't mind, these can be given to you."
The raw materials for mechanical pencils are simple, and the most common metals such as copper and iron can be used. So after he made the mold, he directly produced a large number of them in one go.
After all, since I am taking advantage of Ji Jin Zong’s class, it is only right for me to share some stationery with my classmates.
"Thank you, brothers." The disciple showed a happy expression and took it and gave a handful to the students next to him.
The others hurriedly thanked him. They had just been secretly watching Zhu Changyang use the mechanical pencil and had been very curious about it. As soon as they got it in their hands, they couldn't wait to follow the process.
Everyone was a little uncomfortable at first, and some people, like Jun Shu, subconsciously held the brush with the posture of holding a writing brush, and broke the brush core.
Zhu Changyang then taught the pen-holding posture again, and soon everyone mastered the correct technique.
“Oh, you can really write.”
"The small size of the characters is secondary. I think the best thing is that it can be written quickly."
Several people excitedly shared their experience as if they had discovered a new world.
Some people disagreed, saying: "I think it's just average. The paper will tear if you use a little force. It's not very smooth."
"The paper you are using is not suitable. Try this." Zhu Changyang took out a few notebooks and handed them over.
A few people took it and looked at it, and found that it was a booklet bound with papers cut into pieces about seven inches long and two inches wide.
The texture of the paper is very special. It is different from the bamboo paper they are currently using. It is very thin, but very tough, and the paper feels very smooth.
Several people tried to write on the paper with pencils, and it was indeed much smoother. They immediately exclaimed, "This paper is special. Where did you buy it?"
"I made this myself." Zhu Changyang said.
Modern papermaking technology is very advanced. It can improve the performance of paper by adding various mineral powders such as kaolin and calcium carbonate to meet different uses.
The papermaking technology in the world of cultivation is still in its early stages, mainly meeting the needs of writing with brushes, and the output is not high. In some remote mortal realms, it is even difficult to see paper.
Hearing that this was paper made by Zhu Changyang himself, several people tactfully did not continue to inquire, but only sighed: "I have heard that Zhu Changyang is good at using ordinary materials to make things, and his reputation is well-deserved."
As they were talking, Elder Cen had already arrived at the classroom, and everyone fell silent.
This class is a material theory class. Elder Cen first told everyone about the classification of spiritual materials, how to judge the spiritual content, and the mechanism of interaction between materials and spiritual fire, etc.
It goes without saying that advanced colleges are different. The course design is reasonable and professional, the teachers are very competent in teaching, and they explain things in a simple and easy-to-understand way. Many knowledge points that require a lot of time to understand when studying on your own can be explained clearly in an instant.
Zhu Changyang listened and took notes, and felt that his mind was broadened a lot. After thinking for a while, he took out Si Kou Luo's elementary school homework book that he had bought at the auction from his pocket.
After taking a picture of the exercise book, he roughly flipped through it and remembered that there were notes related to the materials in it, which he could now use to verify what the teacher said.
After finishing the theory, Elder Cen began to ask questions: "In the last class, we talked about drawing runes on weapons to add different functions to them. We gave everyone homework at that time. Now, please tell us what materials can be used to draw patterns on weapons?"
Someone immediately answered loudly: "Cinnabar and gold ink."
"Redwater."
"Green vitriol, night worm blood."
The students answered enthusiastically and soon answered more than ten kinds of materials.
"Very good answer." Elder Cen nodded with satisfaction. "All of the things you just mentioned can be used to draw runes on weapons. But you missed one. Does anyone know what it is?"
The students looked at each other in confusion, and some whispered to each other: "Hey, I've read all the books on pattern painting, and these are the only materials written on them."
"These are the only things I've seen. Did Elder Cen remember it wrongly?"
Elder Cen saw everyone whispering, but he didn't take it seriously. Instead, he smiled slightly and said with a little pride: "If anyone can answer this last material, I will reward him with this material."
As soon as he finished speaking, a hand suddenly rose at the end of the classroom, followed by a loud shout: "It's Chicao Lu!"
Elder Cen: “…?!”
Zhu Changyang originally wanted to be low-key when taking other people's classes, so he was quiet as a chicken at first, but since Elder Cen mentioned reward materials, it would be inappropriate not to fight for it.
Elder Cen didn't expect that someone could actually answer this question. He was stunned for a while before he reacted. He showed admiration in his eyes, "You are indeed knowledgeable. Yes, it is the Blazing Grass Dew. Blazing grass is a hot grass. When rain touches it, it evaporates immediately. Only a drop of dew can remain on the tip of its leaves. That is the Blazing Grass Dew."
One of the students knew about Blazing Grass Dew and asked, "But isn't Blazing Grass Dew used by alchemists to make pills?"
"From this, it can be seen that apart from the skills of your own sect, you rarely know the knowledge of other sects." Elder Cen did not condemn, but said, "The Blazing Grass Dew is not only used for alchemy, but also for refining tools. It's just that the materials are rare and the usage is very special, so few tool refiners know it."
Then he looked at Zhu Changyang and said, "My dear Zhu, do you know how to use Blazing Grass Dew?"
Zhu Changyang said: "The Blazing Grass Dew can be added to the gold ink to enhance the effect of the gold ink, but there is a drawback. The gold ink added with the Blazing Grass Dew will become invisible after drying."
"Yes, that's right." Elder Cen looked at Zhu Changyang with even greater satisfaction and nodded repeatedly, "My dear Zhu, where did you learn this?"
Drawing runes with Blazing Grass Dew is a relatively niche knowledge, and the existing textbooks for weapon refiners do not mention it. Many small sects do not know this. Elder Cen often uses this as a test for his students.
Unexpectedly, Zhu Changyang gave him a surprise the first time he came to listen.
Studio:
[Chang Yang is too strong, he has learned more profound knowledge than the native cultivators! ]
[No, look carefully at the book on his desk. His answer is copied from Skoulo's notebook!]
[? ? So they used the sect master's notes to steal other sect's materials. The Jijin Sect suffered a huge loss! ]
Zhu Changyang was too embarrassed to say that he saw it in your Sikou clan leader's elementary school homework book, so he just said vaguely: "I just happened to see it in a second-hand book."
"You have to be well-read to see that." Elder Cen put on a 2-meter-tall academic filter for Zhu Changyang and said with emotion, "Over the years, there are less than ten people who can answer this question, and one of them has now become the leader of our sect."
Upon hearing this, the classmates showed admiration. Rounding it off, Zhu Changyang's academic level is roughly equivalent to that of Sikou Zongzhu back then.
Zhu Changyang: “…”
Sorry, the person who actually answered the question this time was actually your sect leader.
"Golden ink with Blazing Grass Dew will become invisible after drying, but many runes cannot be drawn in one stroke, which will cause part of the rune to be invisible before it is finished, bringing difficulties to the drawing work. However, a few years ago, someone in Danzong discovered that the tears of mermaids can make the dried Blazing Grass Dew show traces again, perhaps there will be a breakthrough in the future..."
Elder Cen looked at Zhu Changyang kindly, just like any teacher would look at a beloved top student, and continued to ask, "Then do you know what the effects of golden ink mixed with blazing grass dew are?"
The atmosphere was so tense that Zhu Changyang had to answer. However, he couldn't remember so much at once, so he just read from Si Kou Luo's homework: "It can make weapons produce a fiery effect, it can make weapons more powerful, it can be used to draw turtles..."
Elder Cen: “Hmm?”
Not to mention Elder Cen, Zhu Changyang was also stunned for a moment, but he reacted quickly and immediately changed his words: "I mean, it can make the shape of the weapon more simple and beautiful."
"Well, that's roughly correct." Elder Cen nodded, but there was still a hint of doubt in his eyes.
Zhu Changyang smiled without saying anything, and had a hint of doubt about the notes of Sect Leader Sikou.
Studio:
[Ah, I saw it. There is indeed a line about drawing a turtle in this notebook. What does it mean? ]
[My understanding is that invisible ink can be used to draw turtles and curse people without being discovered, but Si Kouluo is the dignified sect leader, so his notes cannot be so naughty, right? ]
[It was so funny, Chang Yang’s image almost collapsed.]
The author has something to say:
Si Koro: Ah, the secret is discovered.
