"On the leftmost shelf at the back."

Ning Xi sincerely thanked

"Thank you Zhenren, Ning Xi knows."

She turned around and went in the direction that the gatekeeper had said, and when she got closer, she found that it was indeed a book about formations.

Ning Xi flipped through several books and found that the content in them was not as detailed as the one given to him by his master.

In fact, Ning Xi didn't know that the formation attainments of the first calculation could be compared to Yuntian Sect, even if it was one of the best in the entire immortal cultivation world, the complete solution of the formation to Ning Xi was his summary of the formation over the years, as well as all the formations he encountered, and how to crack the formation, the above is detailed and detailed, so the formation books on the first floor of this library pavilion are naturally not comparable to the one calculation, even if it is the upper few layers, it may not be as good as the one that is given.

Ning Xi thought that since they were all here, they couldn't run in vain, read all these formation books, and see if there was anything he hadn't seen, and when his master asked, he would have a good explanation, otherwise he really thought that I had used his clan card to show off his might.

Ning Xi was slowly flipping through these formation books, stopping and taking a closer look if he hadn't seen them, and skipping them directly if he had seen them, so that in the morning, Ning Xi had passed most of the few formation books in this corner, and seeing that it was going to be noon, Ning Xi still wanted to go back to eat, and the speed of reading was faster.

After a while, she found that there was a formation book that felt a little different from what it looked, but she couldn't tell what was different, and a faint voice in her heart told her that this book had a secret, but she really couldn't solve it, and wanted to borrow the book, and she didn't bring a spirit stone, Lingxi gritted her teeth and decided to put the book to the gatekeeper first, and then come to pick it up in the afternoon.

Ning Xi walked to the door with the book, and the doorkeeper said without raising his eyes that he would borrow 1 high-grade spirit stone from the book.

Ning Xi stepped forward awkwardly and said when he heard this

"Real person, I didn't bring so many spirit stones when I went out today, can you put the book here first, and I'll pick it up in the afternoon."

As soon as the gatekeeper thought about who would go out without a spirit stone, he looked up and was just about to reprimand, but found that it was Ning Xi who did not bring a spirit stone, and as soon as he saw Ning Xi, he understood that someone went out without a spirit stone, and he naturally couldn't use a storage bag before he could bring qi into his body, and there was no way to bring hundreds of spirit stones on his body without a storage bag.

Thinking that this person is also the apprentice of the second elder, if she doesn't agree to her, she goes to the second elder to complain, and the second elder can't resist it when he starts a temper, and even the great elder can't do anything about him.

The gatekeeper thought for a moment and said

"I'll give you an afternoon, don't take it as an example."

Ning Xi hurriedly said yes, and hurriedly ran outside, and just came out and bumped into someone, I don't know if Ning Xi ran too fast or what, that person was directly knocked away.

The man roared: "Who dares to hit Lao Tzu, Lao Tzu picked your fart." ”

The person who was with him next to him hurriedly helped him up and said, "It's the woman standing over there, it's she who hit the senior brother." ”

Ning Xi saw that he had bumped into someone, so he also stopped and saluted, and said guiltily

"I'm sorry, brother, I accidentally bumped into you."

As soon as the man saw Ning Xi, he found that she had not yet drawn qi into her body, and she was just a mortal, so he mocked
