Heaven-defying Upgrade System

Yuhuntu is very precious. For people like Bai Muyun who particularly desire strength, it is simply a top-grade baby. If she can refine one, she will have improved her strength by one step, but now Liu Fei is I didn't plan to show it to her. She was just a girl after all. After being rejected by Liu Fei, she didn't have the embarrassment to speak again.

Now Bai Muyun can only hope that Liu Fei can finish reading this book quickly, because there is a time limit to enter this library, and if you can’t finish it, you can only wait until the next time you come. At that time, it would cost another five green source crystals. This is the most pitted part of the library.

Although Bai Muyun hadn't read the Yuhun Tu, Bai Muyun thought about it and knew that if this type of formation didn't take a few days, he couldn't read it again. Even if he memorized it by rote, he would be stumped by the difficult language inside.

Originally, Bai Muyun planned to tell Liu Fei that they both watched it at the same time, and one person wrote down half of it, so that he could go back and use it for cultivation. But seeing Liu Fei giving up money so much, it seemed that he didn't care about money and was afraid of being despised by Liu Fei, so he didn't say it.

When an hour passed slowly, Bai Muyun was really innocent, and she was not interested in the martial arts book in her hand. She looked around, looking for any kind person who could give her free martial arts. , Suddenly Liu Fei moved his hand and threw Yuhuntu directly to her.

Bai Muyun was slightly startled, and said, "Ah! What do you mean?" He was at a loss for a while holding the Yuhun map.

Liu Fei said faintly: "I've finished reading it, and I will show you the rest of the time." With that, Liu Fei stood up, and then planned to find another Wu Xue. If divided according to the level of martial arts, the spar needed by martial arts here is indeed a bit cheaper than the contribution points required by martial arts provided by the system. No matter how small a mosquito is, it is meat, so Liu Fei simply does not go to the system. To redeem, just watch it directly here.

However, there does not seem to be any martial arts that can impress Liu Fei.

"What? You've read them all, aren't you lying to me?" Bai Muyun widened his eyes in astonishment, looked at Liu Fei incredulously, as if trying to find traces of lying from him. Liu Fei said lightly: "It's okay if you don't believe it, just return the book to me."

"I won't pay you back!" Bai Muyun smiled, and immediately held the book in his arms, as if it was already occupied by me, and you don't want to go back. Then he looked at Liu Fei and said, "Didn't you say that you have finished reading it? Well, anyway, you also remember the content of every page in the book. I will test you now."

The smile on Bai Muyun's face made Liu Fei feel a little helpless. The little girl made it clear that she wanted to make a fool of herself. Liu Fei didn't care anyway, so she said, "Forget it, I will tell you directly from the beginning."

With that said, Bai Muyun hurriedly turned to the first page, and then listened to Liu Fei memorizing the contents of the book without any haste. After only a while, the expression on Bai Muyun's face became more and more surprised, and she kept turning the pages. I found that the content of Liu Fei's mouth was exactly as recorded in the book.

"Okay, you can stop!" Bai Muyun said hurriedly, her heart could not help being serious, her eyes changed when she looked at Liu Fei, as if she was watching a freak, this difficult and incomprehensible content, he was all remember? OMG! That's awesome!

"How about, do you still doubt me?" Liu Fei asked lightly.

Bai Muyun immediately shook his head, then looked at him seriously, and said, "I admire you! But, can you satisfy my little wish, hey, tell me how you wrote it down in such a short time Yes?" If Liu Fei really has any skills, Bai Muyun will naturally be happy, so that she can write down some martial arts content and sell it in the underground black market of the Baimu clan.

That is a good way to make money.

Liu Fei pointed to his head and said, "Of course it is based on this. If you really want to learn, unless you take off my head and give it to you." Then he smiled slightly and said, "I see. Forget it, according to your talent, it would be nice to be able to write down this book by a tenth. If you really read this book thoroughly, I'm afraid it will cost a lot of valuable green source crystal." Liu Fei When speaking, she gave Bai Muxue mercilessly, but Liu Fei is not really a strong memory, but because of Yi Tianlu's help, his comprehension ability is beyond the reach of ordinary people, so read Understanding a book becomes much easier.

Of course, in addition, even if Liu Fei's talent is not as good as that, let him spend the spar to see, he still has the money.

"Humph." Bai Muyun looked at Liu Fei with disdain, but she was full of envy and jealousy. If she had such a good mind, she waved her hand at Liu Fei and said, "Go ahead, let me study it. This Royal Soul Formation."

This book has been enough for Bai Muyun to read for a while, Liu Fei rolled his eyes and continued to search for books that were useful to him. After reading it casually, Liu Fei was suddenly attracted by a book. It was not a book about martial arts, but a book about spar. After Liu Fei took it out, he discovered that the world's spar can Fusion, and the green source crystal is not the highest quality spar. Through fusion, the green source crystal can also be upgraded to the king of green source crystal.

When Liu Fei took out this book that could integrate the green source crystals, the people around looked sideways and couldn't help but sighed that this young man was really too generous.

Looking at other books, there seems to be nothing that Liu Fei is interested in. These two books are not entirely martial arts, they can only be regarded as aids to cultivation. When she came to Bai Muyun's side, she was seriously studying the Soul Guarding Formation with a serious expression on her face. Seeing that serious look, Liu Fei gently walked to her side and coughed slightly.

Unexpectedly, Bai Muyun's courage was quite small, and he was shocked by Liu Fei.

"Liu Fei! You **** want to scare grandma to death! I have to kill you today!" He said, he leaped towards Liu Fei with his teeth and claws, but Liu Fei's body flashed slightly, and his palm moved directly. He took her in his arms and locked her figure, without any room for movement.

"Wow! You shameless bastard, let me go!" Bai Muyun shouted.

Liu Fei chuckled: "You ran into your arms yourself, okay?"

"Rogue!" Bai Muyun cursed angrily. His pink fist struck Liu Fei a few times. He didn't resist when he saw Liu Fei. Suddenly he felt a little embarrassed, but fortunately Liu Fei let go in time. With her, the two avoided embarrassment. Then Bai Muyun said, "Hey, rascal, I deliberately couldn't finish this book in one day. Will you come back tomorrow?"

Liu Fei frowned and said, "I won't read this book again tomorrow. Do you really think I have money and nowhere to spend it?"
