A shabby narrow hall, a slightly dim oil lamp, a square table with repaired legs, and two stools.
This is all the arrangements for a discussion.
By the way, there was a young man standing next to him with a face of surprise and excitement. Although he didn't understand much, it didn't prevent him from experiencing some knowledge that made him enlightened or surprised.
As for Zhang Shun, Zhang Huiyuan, and Wang Lanping, they had gone back to the room to avoid it. They felt the solemnity of the atmosphere, and they couldn't understand what the two people sitting opposite each other at the square table were saying. They only felt that they looked very powerful.
Consciously create a quiet environment.
"Multiple Pythagorean separately, and combine them to form Xuanshi. Take the square and divide it, which is Xuan. The Xuan diagram of the case can be multiplied by Pythagorean to get two Zhushi, and double it to get four Zhushi..."
There was a piece of white paper lying on the table. Zhang Yan was writing and drawing on it, and he was also speaking awkward words one by one.
Even with the help of pictures and texts, Luo Changshan, who was sitting opposite Zhang Yan and leaning forward with his eyes blazing and focused, still couldn't understand immediately. He needed to interrupt Zhang Yan from time to time, then think about it for himself, and then picked up the paper at hand.
As he was writing and drawing, he would always suddenly realize, "Oh!" and ask Zhang Yan to continue talking.
In fact, this was not the case at the beginning of this debate.
At the beginning, Luo Changshan was in the position of being tested, while Zhang Yan was in the position of being tested. With each question and answer, they were actually getting to know each other. It was similar to a winding road.
Zhang Yan was still a little nervous at first. He didn't know exactly what the miscellany lineage in the Wild Sky Territory would be involved in, and he was worried that he would be labeled a "liar" if he didn't know anything about it. After all, he had been in the Wild Heaven Territory for so long.
, he has experienced many times the special status of the Xue Xue lineage, although its reputation is hidden, but it is noble and popular. Once he is disliked by people from the Xue Xue lineage, it will not be a good thing for him. At least it will be less convenient in the future.
But after asking a few questions, Zhang Yan had a clear idea. He also confirmed some of his previous guesses and some information about miscellaneous studies that he heard from others. The conclusion is that the so-called miscellaneous studies in Huangtian Domain are actually very important.
The mainstream knowledge on earth and on earth overlap with each other, but it is not broken down into various subjects, and because it is suppressed by the mainstream of martial arts, it is still at a very basic stage so far.
What is a foundation? It means that all aspects are still on the road of exploring various basic laws. Some may have been perfected, but some are still in their infancy and lack strong publicity and final finalization.
This is great news for Zhang Yan. In this way, if his knowledge, which seems superficial on earth, is used in the wilderness, it will be a "knowledge base". There is no need for advanced theoretical knowledge, some
Rudimentary elementary school syllabus knowledge is enough to pass the test.
Just like now. What Zhang Yan took out was the description of the Pythagorean Principle by the sage Zhao Shuang in the masterpiece "Nine Chapters of Arithmetic" on Earth. This book is not generally used by elementary schools, but Zhang Yan is very familiar with it. Because
When he followed the master around, the master used this book to enlighten him for a period of time. Not to mention memorizing it by heart, at least he didn't dare to forget it. If I take it out now, will the other person be stunned?
In addition to arithmetic, there are also physics, chemistry...forget about biology, that stuff is too troublesome. Everything Zhang Yan remembers is the most basic thing, but it adds up to a lot. That's thousands of years.
The tower of knowledge slowly stacked up by countless sages on earth was enough for Zhang Yan to squander.
Of course, good things cannot be used without restraint. Avoid looking cheap. You must slowly increase the value bit by bit, and you must also seek some tangible benefits for yourself.
Luo Changshan had forgotten his original intention of coming here. He sat at the square table in the small hall of the Zhang family all night with what Zhang Yan had told him and what he had written. He checked the calculations over and over again and never tired of it. Even his eyes were red.
He still looked like he was still unfinished.
On the other hand, Luo Changshan's apprentice couldn't bear to stay up in the middle of the night and fell asleep in the corner. Indeed, as Luo Changshan said before, their master and apprentice really didn't pay much attention to living conditions. They didn't care if they slept on the floor.
But after all, he was in his seventies. Although he looked energetic, Zhang Yan did not dare to let the old man suffer any longer. After some persuasion, he persuaded him to get a room in a small inn not far from Zhuzui Lane to rest.
. Make an appointment to talk in the afternoon.
That is to say, the Zhang family is too young to stay, otherwise the old man Luo Changshan would not go to the inn.
Zhang Yan had enough cultivation to stay up all night without any problem. Luo Changshan went to the inn and then went to the market to buy vegetables before returning home.
The eldest brother and the younger sister had already gone to the store. Only the old mother Wang Lanping was at home. When Zhang Yan came back from buying vegetables, she quickly picked them up and went to the kitchen to clean up.
"So many dishes?"
"Well, make a few more, and treat Mr. Luo and his disciples to have two drinks in the evening. I'll make a pot of wine later." Zhang Yan was cleaning up the leftover medicine residue from yesterday's alchemy in his bedroom, while giving
The mother who was busy in the kitchen replied. Although the alchemy was disturbed yesterday and she could not continue all the time, she still made two furnaces. Of course, they were all useless because the alchemy she made was Biqing Dan.
However, after practicing several times, Zhang Yan can directly feel his progress in refining the Biqing Dan. Although he is still far from successfully refining the Biqing Dan, at least he can handle the refining.
All the details of the first 40% of the project were completed. The progress was actually much faster than he expected after the first failure.
Moreover, Zhou Cang was sent much more medicinal materials this time than last time, a full ten portions. It seemed that he was preparing to stock up on some elixirs.
Zhang Yan did not refuse Zhou Cang's little thoughts. He still had a lot of bone-strengthening pills in his hand that he couldn't use. They were all prepared to deal with Zhou Cang's favor. And the more pills Zhou Cang sent, the more he could use them.
Try your hand more frequently and get the Biqing Pill out as soon as possible.
Now Zhang Yan feels in his heart that alchemy is like a skill in many games. In addition to the talent threshold, proficiency is also required.
"Yan'er, come here."
"Come on, mother. What's going on?" As soon as Zhang Yan had finished getting rid of the medicine residue in his room, he heard his mother calling him in the kitchen and hurriedly walked over.
"Mom, let me tell you something."
"Huh? You said."
"When you are making wine later, make an extra jar of good wine. Send it to Wangjiazhuang outside the north gate of the city tomorrow to find a family named Wang Shi. Tell them that I brought this wine to them. If they give you anything in return,
Just bring it back. If they don't accept the jar of wine, don't force it, just turn around and leave."
"Wangjiazhuangzi? Wang Shi? Mom, our family is related there... Oh! Mom, is this a probe gift for eldest brother?" Zhang Yan was not slow to react, and immediately responded. At the same time, he secretly said to his family
My movements are so fast! Will I help my brother find the right one?
