15.

Wang Tianyu is not in a good mood today, in his opinion, yin-yang arithmetic is a sacred avenue, and it is by no means something that ordinary cats and dogs can touch casually.

Originally, in the Qingling Academy, students at the seedling level were not qualified to learn yin-yang arithmetic, and only after they were promoted to the leaf level could they have the opportunity to come into contact with yin-yang arithmetic.

Moreover, most people only stay at the level of yin-yang arithmetic, which can help them control the spirit armor. And those who are truly proficient in yin-yang arithmetic and can use yin-yang arithmetic to refine the spirit armor are rare, and only a true pride of heaven can do such a thing.

Because the spirit armor of Qingling Island is the foundation of its survival, such a person has a very high status in Qingling Island.

Wang Tianyu's father is one of the few people on Qingling Island who is truly proficient in yin-yang arithmetic, and he is also the arithmetic of the Yin-Yang Society!

Therefore, Wang Tianyu has had many opportunities to come into contact with yin-yang arithmetic since he was a child, and at a very young age, he showed his talent for yin-yang arithmetic, and was called Tianjiao!

So after Cheng Li entered the class as a transfer student and stole the limelight, Wang Tianyu felt a little unhappy in his heart. But the fact that Tianlinggen was there, so it was not easy for him to stir up trouble.

However, now, he found out that Cheng Li actually wanted to participate in yin-yang arithmetic, and he shamelessly said that he wanted to win, which made Wang Tianyu extremely angry.

"I don't know the frog at the bottom of the well, you just awakened the spiritual root yesterday, and today it's like participating in yin-yang arithmetic? Do you understand yin-yang arithmetic? I'm afraid you don't even understand the basic principle of change between yin and yang. ”

Looking at Wang Tianyu's disdainful look, Cheng Li felt a little inexplicable, and could only say modestly: "For yin and yang arithmetic...... I guess I know a little bit. ”

"Understand? haha!"

Wang Tianyu felt like hearing the funniest thing in the world, and laughed.

"I know a little bit, this is simply the funniest joke! I really don't know what to say! Tomorrow in the Yin-Yang arithmetic competition, I will let you understand what arithmetic is!"

After speaking, Wang Tianyu seemed to feel that talking to Cheng Li was very identious, with a look of disdain, completely ignoring Cheng Li, and walked past him like this.

was made by Wang Tianyu to make this play, which made Cheng Li is second monk confused.

"There's something sick about this thing, isn't it? Why did you suddenly come to me and say such inexplicable things, and I didn't ask him to provoke him. Cheng Li said with a puzzled expression.

At this moment, a gust of wind struck, and then Ye Lin's figure appeared directly in front of Cheng Li.

"What's the matter, are you okay?I just saw Wang Tianyu, did you have a conflict with him?" Ye Lin said with concern.

"It's nothing, it's just that he suddenly came up to me and said something inexplicable, but I don't care. Cheng Li waved his hand.

With Cheng Li's temperament, he didn't take this episode to heart at all, and at this time, he just wanted to quickly find some information on yin and yang arithmetic and study it carefully.

Although he knows more about binary languages than anyone else on the island.

But after all, they are two worlds, coupled with the difference in the times, so that the binary language that Cheng Li understands is still incompatible with the yin-yang arithmetic on the island, so Cheng Li needs to understand the entire framework of yin-yang arithmetic on the island as soon as possible, so that he can translate the content he is familiar with into the form of yin-yang arithmetic that people on the island can understand.

Thinking of this, Cheng Li opened his mouth and asked, "By the way, Senior Sister Xiao Lin, where can I find information on yin-yang arithmetic here?"

Ye Lin happily replied when she heard this: "Yes, our Qingling Academy has a large library of books, and there are all kinds of materials in it, including yin-yang arithmetic. ”

"Then can I go in?" asked Cheng Li.

"Yes, the Great Elder only made a special order yesterday that all the contents of the Yin-Yang Arithmetic in the Library Pavilion would be open to everyone for free for three days. You know, this used to be a qualification that had to be exchanged for contribution points. ”

Cheng Li's eyes lit up and said, "Then what are you waiting for, take me over quickly." ”

So, the two walked side by side towards the library on Qingling Island.

And in the study room at the top of the school hall that Cheng Li didn't know, the deep eyes of the Great Elder were looking at Cheng Li's distant back.

"Master's hexagram...... Is it really fulfilled on him?, is there really a miracle?" muttered the Great Elder.

......

After coming to the library pavilion, Cheng Li was hungry and immersed in the sea of books.

I see, although this yin-yang arithmetic is not supported by many mathematical theories, it also understands its root through its own mystical way. ”

After reading four or five books in a row, Cheng Li has roughly understood the principles and basic structure of yin-yang arithmetic.

"This spiritual root awakening is really a lot of benefits, even the speed of reading has become faster, and there is also the function of memorization, and the memory is much better than before. Cheng Li said with emotion.

If he hadn't awakened the spiritual root, Cheng Li would definitely not have been able to read four or five thick books in just three hours.

Cheng Li felt that his head was extremely bright, and there was no sense of blockage at all.

Whether it is memory or reflexes, they are much stronger than before, which makes Cheng Li feel reborn.

Now that we have a basic understanding of the principles and structure of yin-yang arithmetic, the next step is to try to translate some mathematical theories on the earth, as well as computer principles, into the terminology of yin-yang arithmetic. Some words that have not appeared in this world should be avoided and expressed in other ways, so as to avoid attracting unnecessary attention from others. Cheng Li thought in his heart.

In this way, Cheng Li spent the whole night in the library and studied very intently.

In addition to studying some yin-yang arithmetic, Cheng Li also took the time to check some information about Blood Demon Island, and even checked the population data of Qingling Island over the years, and he didn't know what he wanted to do.

However, consulting these materials only took up less than half of Cheng Li's time, and most of the time, Cheng Li was concentrating on studying yin-yang arithmetic.

Cheng Li's personality is a very focused person, and he strives to do his best in everything he does.

At this time, he studied yin-yang arithmetic, and it was even more out of control, and when he came back to his senses, the sky was already bright.

"Well, it's dawn, time flies. ”

Cheng Li stretched his waist and found that he was not sleepy at all, but felt a little refreshed.

"It seems that this cultivation is really beneficial, and I don't even get sleepy when I stay up late. ”

Cheng Li shook his head and walked out of the library pavilion.

At this time, Ye Lin was already standing outside the library pavilion waiting for Cheng Li.

"Wow, Cheng Li, you are so exaggerated, you actually read a book in the library all night. ”

"No way, time is running out, I have to hold on to it temporarily. ”

"Okay, then now I'll take you to the Yin-Yang Arithmetic Competition, the competition will start in half an hour!"

After speaking, Ye Lin couldn't help but take Cheng Li's hand, and then the imperial envoy body method suddenly soared into the clouds.
