"What are you talking about?" Lu Meng looked at the dense floating boulders below, and said disappreciatively: "Those are all pumice stones, as for whether it is a floating island fragment, I don't know, anyway, it was there a long time ago, and we have never paid attention to it." Pen, fun, pavilion www. biquge。 info”

Ye Sanshan suddenly said: "I heard the master mention it once, those should be the fragments on the Heavenly Dome Peak." ”

"Has Heavenly Dome Peak been disintegrating?" Tianyou asked suspiciously, "Why are there so many fragments?"

"I don't know about this, but it's definitely not a recent collapse, but I saw Uncle Shi repair it once before, and reintegrate some large pieces of pumice stone into the Sky Dome Peak. ”

"Uncle Shi has also repaired the Heavenly Dome Peak?" Lu Meng obviously knew the news for the first time.

Ye Sanshan was accustomed to this and said: "Uncle Shi has actually been repairing Tianqiong Peak all these years, but there are too many fragments, and there are no fewer after so many years of repairing. ”

"Do we have so many fragments in Heavenly Dome Peak?" Lu Meng asked in surprise, "I haven't paid attention to it before." ”

"You've only been a few years old? Okay, let's not talk about that. Brother Tianyou, I'll take you to see other places, right?"

Tianyou nodded and didn't ask about the Fushan fragment again, and instead followed Ye Sanshan to continue to visit the other places of the Treasure Weapon Sect.

The few sects visited before were all visited by Bai Bingyu and Bai Bingqian with Tianyou, so they were a little out of order, and there were a lot of things to see, but they couldn't find the point. As the eldest disciple of the Great Sect Master of the Treasure Weapon Sect, Ye Sanshan knows the Treasure Weapon Sect well, and it is straightforward to take Tianyou to visit.

After leaving the edge of the Heavenly Dome Peak, a few people first went to visit the "Duowen Palace", where there were many disciples of the Treasure Weapon Sect who were sitting in danger, listening intently to an immortal chief teaching mathematics at the top position.

Yes, that's right, they're teaching math.

Tianyou was stunned for a short time because of surprise, but Ye Sanshan thought that Tianyou didn't understand these mathematical knowledge, and kindly explained: "This is called Shu (shu) number (shu), it is a kind of knowledge used to calculate, you must have been exposed to it when you usually buy and sell things, but it is just the simplest use, and ordinary people will not learn this way." However, the number of techniques is the principle of heaven and earth, which can deduce the changes of heaven and earth, and can calculate the discrepancies of money and goods, which is actually a practical science. ”

"I understand. After Tianyou reacted, he walked down the steps, and then began to speak, for fear of disturbing the disciples who were attending the class inside. "I've studied math, and my grades are pretty good. I'm just surprised that Zixiao Palace actually specializes in teaching the science of counting, which really surprises me. ”

"Actually, not all sects have to learn. Bai Bingyu added: "Only the three sects of Spiritual Law, Treasure Weapon and Danding force disciples to learn basic arithmetic operations, like my Divine Weapon Sect only has elective training, while the Tianwu and Beast Control Sects have no requirements at all. ”

Lu Meng followed: "Even if it is our Treasure Weapon Sect, it is not mandatory to learn to a certain extent. In fact, most disciples only need to understand some fur is enough, and only disciples who want to drill and develop weapons need to study in depth. ”

Ye Sanshan suddenly reacted at this time that Tianyou said that he had learned the number of techniques, and confirmed with some surprise: "Senior brother of Tianyou, have you learned the number of techniques?"

"Well, I've learned a few. Talking modestly, Tianyou was thinking in his heart: "Master, I also graduated from a bachelor's degree, and I was shoehorned abroad by my father to study MBA courses for two years, although I took care of playing in the two years of studying abroad, and I didn't listen to the lectures very seriously, but we have finished the nine-year compulsory education, and no matter how bad the math score is, it is better than these Taoist priests in the Shenzhou Continent, right?"

Of course, Ye Sanshan didn't know what Tianyou was thinking, so he asked Tianyou very seriously: "It's really rare for a disciple to learn the number of techniques before getting started, where have you learned it, junior brother Tianyou?"

"Addition, subtraction, multiplication and division are all the basics of the basics, of course I have learned, trigonometric functions and multivariate equations are not problematic, calculus is not good, basically almost forgotten. ”

Ye Sanshan looked at Tianyou with a confused expression and asked, "What is a triangle containing numbers, multiple circles and a thorn square city? After addition, subtraction, multiplication and division, shouldn't you first learn the five elements of yin and yang and the heavenly and earthly branches?"

Tianyou was also stunned for a moment, and then reacted that the academic names on the two sides might be different, and hurriedly went back to the circle and said: "Oh, I learned the number of techniques from the accounting room in the caravan in the Western Regions back then, so some things may be different from the name of my Central Plains region." Why don't you help me explain to me what the techniques here are, and I'll probably know the situation after comparing them. ”

Ye Sanshan did not doubt him, and explained to Tianyou very seriously.

After listening to Ye Sanshan's explanation, Tianyou realized that he really thought about the number of techniques too simply, thanks to the different names on both sides, otherwise he would have almost made a joke just now.

The magic of the Shenzhou Continent turned out to be not pure mathematics, it was more like a fusion of mathematics and some occultism.

The arithmetic of the Shenzhou Continent includes two parts: arithmetic and mathematics, of which addition, subtraction, multiplication and division are the arithmetic parts, while the five elements of yin and yang and the heavenly and earthly branches belong to mathematics.

Arithmetic is pure mathematics, but the development of the Shenzhou Continent in this area is very general, multiplication and division of more than two digits and simple trigonometric function relationship calculation is the pinnacle of mathematics in the Shenzhou Continent.

However, there is still mathematical knowledge that is not available on earth, and this Tianyou has not been exposed to it before. Like what Yin and Yang Five Elements he has heard of, there is only one name left in the Heavenly Stems and Earthly Branch, as for the more complicated Hetu Luo Book, it is completely the Book of Heaven, Tianyou simply listened to it and determined that he couldn't handle this kind of thing at all.

After roughly understanding the number of techniques here, Tianyou told Ye Sanshan that he could only do arithmetic, and he didn't understand anything else.

Ye Sanshan was not too surprised by this answer, and after chatting for a few words, he began to pull Tianyou into the gang, and said vigorously: "You have such a good mathematical foundation, it's a pity not to come to the Treasure Weapon Sect." ”

Tianyou still refused to express his position, and Ye Sanshan had no choice but to take him to continue visiting.

Leaving that school, they visited a place that looked like a small handicraft workshop, and many disciples were studying carpentry. According to Ye Sanshan's explanation, this place is a workshop for new disciples to practice, specializing in using ordinary wood as the main material to make various disposable props.

Out of this carpenter's workshop-like place, several people soon visited the higher-level smelting area, where many disciples shared an iron-making furnace to make high-end equipment, but Tianyou was surprised to find that there were people here who were actually making flying swords.
