It's still okay to skip class in the lecture hall of the other hospital, such as asking Tantai Qiyang to help report, or pretending to go to the toilet, etc., Yang Yu seems to be very familiar with it, as if he did it before, but why? Yang Yu didn't think about it, he didn't have the time to ponder the fragments of memory in his mind.

He has now saved more than a hundred books. Although he was reading books too fast, Yang Yu still felt that his speed was too slow in the face of the vast collection of books in the old book building, and many of the things he was very interested in were only introduced in many books! There was not much actual content.

For example, the formation knowledge he wants to know, which involves a lot of mathematical aspects and Yili knowledge, these things, according to Yang Yu's reading speed and comprehension ability, will soon be a little insufficient!

This is only related to his lack of what he needs to learn in the beginner class, but those basic knowledge are not necessarily very useful in the textbook! Yang Yu does not know much about many elementary knowledge.

Yang Yu still decided to read the book by himself, but it would be best if someone could really help him understand something more basic, but Yang Yu knew that he was expecting this for the time being.

On this day, he continued to rummage through books in an old bookstore, this time he was looking for some books on the ease of understanding of mathematics, regardless of whether other knowledge was useful or not, at present he was mainly focused on the study of formations, whether it was for the help of cultivation in the future, or the competition with Donghuanglun, he needed to understand the knowledge of formations as soon as possible.

This stack of more than a dozen books was placed on the table, and the teacher in charge of registration did not raise his head, grabbed the above copy of "Yi Li Miscellaneous", turned a few pages and threw it aside, and after grabbing the following book of "Nine Chapters of Mathematics", turned a few pages, and threw it aside.

"Although the number of easy spells is the foundation, but the study of the formation is not in this peep, you need to understand the real Fu Seal of the study to do, the calligrapher must be able to write, can write but not necessarily draw! can draw but may not understand the meaning!"

After saying this, the teacher slowly raised his head, Yang Yu was shocked by his words, but after seeing his face, he suddenly shouted in surprise: "Mr. Wu! is it really you?"

This person is the same Mr. Wu who was the managing deacon in the Beilin at the beginning, Mr. Wu is one of the few people Yang Yu wants to repay in this world, and he asked Shi San to give him one of the roast chickens that he thought were the best.

At the beginning, Mr. Wu wanted to help Yang Yu when he enrolled students in that cold food, but because of the recommendation system, it was not allowed, and his status in the Zhulin Annex, Yang Yu was not admitted to school more than three years ago.

But in fact, the main reason for that time was that Yang Yu was framed, locked in a cell, and missed the time to register, but Mr. Wu didn't know about it.

As soon as Yang Yumeng saw Mr. Wu, he naturally felt cordial and surprised, so far, he is in the Bamboo Forest Courtyard, and he has no acquaintances, and sometimes if he can't say a few words to Tantai Qiyang, he doesn't even have someone to talk to.

Mr. Wu looked at him and smiled gently: "Sure enough, it's you, I can't imagine that three years later, we will still meet in the other courtyard!"

"Yes, yes, Mr. Wu, after three years, I often think of you! I really can't imagine seeing you here today!" Yang Yu couldn't hide his excitement in his heart.

Mr. Wu made a gesture on his lips and said to Yang Yu: "This is not the place to talk, you come with me!" I read a book

Mr. Wu led Yang Yu to the duty room, told one of the teachers inside to help him look at the study building, and then led Yang Yu to the back of an old study building! There is a small room here, which is Mr. Wu's bedroom.

The room was small, but neat and elegant, with some flowers and a few books on the table, and except for two chairs, there was only a bed!

But Mr. Wu seemed to be very indifferent and very satisfied, and the two sat down to gossip, although there was not even a glass of water in the room, but Yang Yu felt that it was very comfortable here! So he told Mr. Wu everything he had experienced in the past three years.

Of course, he has a friendship with the little emperor, because it is not important to the academy, so he brought it all at once, and then the identity of the secret guard in his palace, this is very secret, not that Yang Yu does not trust Mr. Wu, but he only feels that it is useless to say this kind of thing, and people are not necessarily interested.

Mr. Wu is a cultivator, Yang Yu knows this when he releases his perception, and cultivators naturally don't care so much about these mundane things.

After Mr. Wu heard what he said, he was surprised in his heart, when he was in the stele forest, Yang Yu, a person who did not know the knowledge, was able to look at the Guanglin stele and realize the Tao, and opened up the already different knots in one fell swoop.

Although he couldn't enter the Bamboo Forest Courtyard to study, he couldn't imagine that he would be in such a situation within three years! It seems that this son is not destined to be an ordinary person! And he must also be a chosen one.

"Xuan Zu actually accepted you as an apprentice? I can't imagine that you have embarked on the path of cultivation from this, it is really unexpected!" Mr. Wu sighed.

Yang Yu said: "If it wasn't for Mr. Wu to untie the knot for me, Yang Yu would not have come to this step today, now I follow the master's request and come to the other courtyard, I want to come to the master's old man's house to do important things, I can't teach me by my side, it is better to come here to study, he said that my opportunity is here, but I don't know where it is!"

Mr. Wu was a little distracted, and after a while, he looked at Yang Yu and said: "Xuanzu's status in Xuantian Sect is extraordinary, although he is not tolerated by the sect master, but it is likely that he doesn't want to stay in Xuantian Sect, in my opinion, the way Uncle Xuanzu cultivates, let him do things from his heart, there must be a reason! Since he said that your fate is here, then there must be no mistake!"

"By the way, Mr. Wu, why don't you come here when you don't manage the Forest of Steles?" asked Yang Yu.

Mr. Wu said: "Because I did something wrong! Hehe, don't talk about me, my cultivation should be like this, I am very content with this, but you, you defeated the Eastern Emperor Lun when you first entered the other courtyard, and you think about the Xuantian Sect that has already offended, what do you want next?"

The competition between Yang Yu and Donghuanglun is not over, and he also knows that what he does will definitely be disliked by Xuantian Sect, but since he has done it, he will no longer think about this problem, and at present, in addition to studying, the most important thing he wants to do is naturally to understand the formation.

"Mr. Wu, what is the formation on the Dao Yi Pavilion?" Yang Yu suddenly asked.

"Do you know you have a formation on it?" Mr. Wu asked in surprise: "No wonder, no wonder ......!"
