"Sorry, I cheated." Ray looked at the dealer and the other two guys who made the bet, and silently said sorry in his heart.

The [Evil Shadow Divine Machine] is not just a small server, it also has similar functions to the [Ten Thousand Divine Machines] - monitoring and information transmission functions.

However, the information transmission target of the [One Series of Ten Thousand Divine Machines] is the [Wisdom of All Ones], but the transmission target of the [Evil Shadow to the Divine Machine] is the Demon God of the Thunder Movie.

The shroud range of [Wisdom of All Talents] is only an entire blade island and the nearby seas, and the signal shroud range of the thunder movie is the entire Teyvat continent, and this technology can't be darker anymore.

Although Lei Movie will not always pay attention to Blade Lian Lingyi, he will occasionally pay attention to Blade Lian Lingyi's movements, after all, this guy still has a little bit of talent, and his kerndo talent is really good, maybe he can grow to the extent that he once used to be Sasa Lily.

In the recent attention, she learned that this guy feels that his math level is a bit insufficient, and he needs to upgrade.

And mathematics is not prevalent in the Teyvat continent, only Kanria and Sumeru people occasionally study it, although Blade Lian Lingyi has taught many people on Blade Island through [a series of ten thousand divine machines], but these people don't talk about the mathematical problems involved in the mobile phone algorithm, and there is almost no one who has learned advanced algebra.

At most, these islanders learned simple addition, subtraction, multiplication, and division.

But these are enough for these islanders, at most to learn the principles of parabola and refraction to spear fish.

After all, they don't have to study the mysteries of the world, and the mysteries of the world have nothing to do with them.

Therefore, for them, it is the same whether they study mathematics or not.

Even Ling Yi didn't learn math well in his previous life, after all, if he studied well, he wouldn't graduate from college and wash dishes.

However, in this life, mathematics has become instinctive, coupled with the use and research of mathematics over the years, his mathematical theory can reach LV6 (1.5/100), and mathematical application can reach LV5 (39.9/100)

He has just entered the field of being called a mathematician, but he is only proficient in basic mathematics and some advanced mathematics (high school mathematics), and he only knows the knowledge of advanced mathematics, linear algebra, number theory, etc., and does not know why it is, that is, he can use mathematics to analyze everything in the world by virtue of his special race.

And his rating still has a certain amount of moisture, and his grade is so high because the mathematics of the whole Teyvat is underdeveloped, which allows him to exploit the loopholes in the rating system.

His mathematical level is placed in a place where mathematics is developed, such as his hometown in his previous life, which is just the level of LV4, but it makes him tremble when he arrives here.

······

Blade Ling Yi began to review mathematics, and studied the application of mathematics, digging out the mathematical knowledge of his previous life from his mind and began to relearn and understand it.

It's not a difficult thing, the more difficult thing is that I didn't study well in high school in my previous life, and there is a bit of a lack of advanced (high school) mathematics, and there is more knowledge above, such as the application of advanced mathematics, but there is still a big gap between it and advanced mathematics.

There is a blank space in the middle, which is called the blade Lian Lingyi's claw.

You can only use advanced (high school) mathematics to analyze advanced mathematics applications at the next level.

Hard nibble··· Can you actually gnaw and move?

"It's really great that [Evil Shadow Divine Machine] can actually improve my math ability." Blade Lian Ling Yi sighed.

What he didn't know was that a certain Lei movie had put in a lot of mental work in the back, and used his science brain, which was also second to none among the demon gods, to smooth out all the problems of advanced (high school) mathematics and advanced mathematics applications for him.

As long as he uses the [Evil Shadow Divine Machine] to perform mathematical calculations, this mathematical knowledge will subtly enter his brain.

Ray Movie: "Just kidding, do you really think that math is something that you can gnaw if you say you can gnaw hard?" If I hadn't helped you, would you have been able to touch the door and talk about it. ”

But no matter how much Ray Movie is, he is secretly trying hard.

It's not like the palace master of the Narukami Shrine, who doesn't talk about martial arts, and directly sends people to enter.

"My lord, a famous post has arrived, it's Mr. Yule Zhai from Yingxiang Mountain." Tenmu Uji said to Blade Ren Lingyi, who was studying mathematics behind closed doors.

"Huh? What's the situation, I'll take a look at the name post. ”

Even Ling Yi was confused when he saw it.

In the end, he and Youle Zhai are just nodding friends, although there is a little friendship, but there is no deep friendship, but a cursory look at the two of them on this post is the same as friends who don't talk about anything.

Probably the content is that he heard from Miyaji-sama that his little friend Blade Ren Lingyi is now serving as the fifth clerk of the shogunate, and recently Arikusai himself has been bored in the mountains, so he came down the mountain to visit Inazuma Castle. He has a wide range of friends, but it's a pity that the acquaintances of the recent stubble are all ancient, and he doesn't want to go to the shogunate to spend the night in a circle, so he can only find the familiar demon of Blade Lian Lingyi to spend the night, hoping that Blade Lian Lingyi can agree.

When the time comes, he, the old driver, will drive with Ling Yi with the blade.

After reading the famous post carefully, although he was a little confused, he could still see that this Youle Zhai was sent by Lord Huzhai Palace.

But what is the reason, it is estimated that Lezhai himself does not know.

However, he didn't want to offend Ling Yi ruthlessly, so he used metaphors to write these things into the famous post.

"Please come in, forget it, I'll go myself." As he spoke, Ling Yi got up and walked towards the gate of the small courtyard.

When Youle Zhai was welcomed in by Blade Lian Lingyi, he still said vigorously: "Trouble Brother Blade Chain." ”

"Ah, don't bother, I have heard that Brother Xuanhu (another name for Le Zhai, there is Le Zhai for the black fox, so it is also called Xuanhu) is erudite and talented, it just so happens that my brother has recently studied mathematics, encountered one or two problems, and wants to ask Brother Xuanhu for advice." Blade Lian Ling Yi said after the two of them sat down.

"Oh~ take a look." As an elegant person, Youle Zhai has also studied the arithmetic.

"What does that mean?" Youlezhai asked, pointing to an unknown symbol.

"Oh~ This is a mathematical symbol, which represents the root number." Blade Lian Ling Yi said.

“···” Xuanhu Youle Zhai was defeated, but he was also a really elegant person, and directly said generously that he couldn't understand the mathematics of Blade Lian Lingyi, and lived here with peace of mind, to say that he would live for about two or three months.

Blade Ling Yi also continued to study mathematics, after all, although it was more difficult to gnaw, he was very sure that his mathematical level continued to rise, after all, the progress in the rating system would not lie, and every bit of proficiency improvement was an affirmation of his efforts.
