When he woke up, what Luo Changshan remembered most was Zhang Yan's superb discussion on graphics. He was able to discover such magical laws in arithmetic and deduce specific...well, laws, yes, It's called the law, he remembered what Zhang Yan said at the time.
What Luo Changshan was even thinking about was the strange book called "Nine Chapters of Arithmetic" that Zhang Yan only mentioned.
Luo Changshan was sure that it was definitely not something that could be accomplished by one or two people, or even by hundreds of generations. The discussion on "Pythagorean Principle" alone in it made him study all night, and he still has some unexplained details that need to be pondered over and over again. How grand and wonderful will the rest of the chapter be?
While sighing, Luo Changshan was not really dazzled by the wonderful and shocking knowledge that Zhang Yan threw out. He always remembered his original purpose of rushing to Langyuan City this time. It's just that I haven't touched the context yet.
For example, where are Zhang Yan's roots? Those studies clearly have strong characteristics of the miscellaneous studies lineage, and many of them are even ahead of the current miscellaneous studies circle. But there are mysterious methods like alchemy that have nothing to do with miscellany. What's the explanation for this?
What puzzled Luo Changshan the most was that Zhang Yan's school had remained unknown. It even seemed that if Zhang Yan had not committed a serious crime and had to rely on means to survive, their group would probably have to continue to hide it tightly. They are so strict that even the academic circle knows nothing about them.
Last night Luo Changshan also asked Zhang Yan about who he studied under. But the result surprised him again.
"I do not know!"
At that time Luo Changshan was so angry that he almost vomited blood. Is there any weird thing about learning so much but not knowing who the master is? Anyway, Luo Changshan didn't believe it, so he regarded it as Zhang Yan's crude perfunctory treatment and didn't want to talk about his sect.
But there is one thing that Luo Changshan can be sure of after yesterday's contact, that is, Zhang Yan is not a cunning person, and what he has learned is extremely solid, and there are new ways and methods that are developed outside the miscellaneous academic circle.
To be honest, Luo Changshan was itching. It's not that I covet other people's knowledge, I'm just curious. I felt that I should stay in Langyuan City for a few more days this time. At least some of the subtle things in "Nine Chapters of Arithmetic" should be reproduced.
But Luo Changshan couldn't keep his face if he asked for it in vain. The "Pythagorean Law" that Zhang Yan told him yesterday already made him feel a little guilty. He had learned in vain the knowledge that others had studied for generations. Zhang Yan seemed to know some of the things he could get his hands on, which put Luo Changshan in trouble.
"Forget it. There is a lot of knowledge in the miscellaneous studies circle, and many of them have cross-references. At worst, ask Zhang Yan which aspect he is interested in and let him choose. I think if I can use this to get a new path to miscellaneous studies If you think about it, people in the circle will agree with it.”
In the end, Luo Changshan made up his mind and couldn't wait to continue chatting with Zhang Yan.
Before it was time, disciple Zeng Hao came down from upstairs in a daze. He finally woke up and didn't panic when he didn't see his master. After washing, he was going to go downstairs to have something to eat.
"master."
"Yes. Ask for what you want to eat. Move quickly. After eating, we will go to Zhang's house and sit down." Luo Changshan was in a good mood and was sorting out the knowledge categories in the general academic circle in his mind. At the same time, he was also recalling how many books of various categories he had stored at home so that he could exchange them with Zhang Yan.
Three meatloaf and a bowl of vegetable porridge were Zeng Hao's meal. He wolfed it down and finished it quickly.
"Master, do you think Zhang Yan and I are the same generation?" It was rare for Zeng Hao to see a person from the miscellany without a beard, and Zhang Yan gave him a very good impression. He was kind-hearted and very capable. He could actually Give lessons to the master. He also hopes to get more familiar with Zhang Yan.
Luo Changshan was stunned for a moment, shook his head and replied: "It's hard to calculate. He doesn't want to say where his master came from, so there is no way to calculate his seniority."
"Then judging from your age, are you the same generation as me?"
"That's about right. He's probably about ten years older than you."
"Hey, Master, since we are peers and have the same knowledge, do you think that if I call him "Senior Brother" and often go to him to ask questions, will he pay attention to me?" Zeng Hao blinked and said I came up with a little idea that suddenly came to my mind before going to bed yesterday, and asked the master if it was feasible.
"This..." Luo Changshan's eyes lit up. He did not expect this idea from his apprentice. Maybe... "Well, we will stay in Langyuan City for a few more days recently. You can give it a try. That Zhang Yan doesn't seem to be a difficult person to get in touch with. But you have to be measured when you speak and ask questions, and you can't let him get in touch with you." People find you boring, understand?”
"Don't worry, master, I understand." Zeng Hao smiled and nodded repeatedly. Just like Shi Xuan's evaluation of him before, he is not just "little smart" as Luo Changshan said modestly, but also has great wisdom.
Zeng Hao's idea is, how can he be so knowledgeable that even the master has to listen carefully? The master has a different status, so it's hard to ask, and he can't go. As a peer, he can always ask some indirect questions, right? Learn a little bit, this thing is absolutely guaranteed to make money without losing money. At worst, I'll help run errands. Zeng Hao knew the wheelchair at the woodworking shop at a glance and could help him to some extent. After getting to know the Zhang family well, Zhang Yan can't just say nothing and teach nothing, right?
Patting his apprentice on the shoulder, Luo Changshan's mood suddenly became better. He thought to himself: It's better to be young. If you say shameless, then be shameless without hesitation. It's not like this old man, who has been relying on an old face all his life. The future generations are terrible! I will be Zeng Hao's master at that time, so I should test him to see how he learned from Zhang Yan. Is that okay?
The master and apprentice left the inn with smiles on their faces. As soon as they reached Zhuzui Alley, they saw Zhang Yan coming out. They laughed at each other and said it was a coincidence, so they went back to Zhang's house together.
"I was just going to see how senior was resting, but I didn't expect that senior came first."
"Hahaha, as we get older, we have less sleepiness. If I hadn't waited for this boy, I would have come to see Mr. Zhang just after noon. Mr. Zhang's lecture last night made me enlightened. I benefited a lot from it, so I shamelessly brought some today. If you have any questions, I hope Mr. Zhang can give me some advice."
One called "Senior" and the other called "Sir", and each called his own name, but they all responded in a tacit understanding.
"Senior is joking. Zhang Yan is a backward student. He has little knowledge and dares to give advice to his seniors. It's better to ask seniors to correct him. And when it comes to doubts, Zhang Yan has many doubts that need to be solved by his seniors." Zhang Yan said while serving hot tea to Luo Changshan. , there is obviously some foreshadowing both inside and outside the words.
