Heaven-defying Upgrade System

1"Okay." Bai Muyun seemed to have no choice but to agree with him. She wanted to let him go, but her eyes kept staring at Liu Fei.    

    

"What is it? Why aren't you moving aside?" Liu Fei asked.    

    

Bai Muyun asked, "Don't tell me you want to go to the library?"    

    

Liu Fei frowned slightly and said, "Yes. Did I come here just to meet you?"    

    

"Perfect. I also want to go to the library. If you don't mind. We will go together. " Bai Muyun said and looked at Liu Fei's eyes at the same time, as if she was provoking him. However, with Liu Fei's temper, he naturally would not be afraid of others provoking him. He agreed without saying anything.    

    

Bai Muyun chuckled and followed Liu Fei. No one knew what was going on in her mind.    

    

Liu Fei shook his head. No matter what she thought, Liu Fei did not care. This little girl was still very young in front of him. Whether it was her cultivation or shrewdness, she was still a lot weaker than him.    

    

The two of them went in together and were speechless along the way. However, Bai Muyun would peek at Liu Fei from time to time. Liu Fei's heart slightly moved. Could it be that this little girl had taken a liking to him? But Bai Muyun was pondering in her heart, what exactly was the hidden weapon that Liu Fei had hidden in his hands at that time? It could actually escape her eyes? She really wanted to know.    

    

"Hey, what's your name?" Bai Muyun asked as she walked into the library.    

    

"Liu Fei."    

    

"My name is Bai Muyun!" She said.    

    

Liu Fei nodded, indicating that he heard her.    

    

Entering the library, Liu Fei originally thought that this little girl would be separated from him very soon. Who knew that she seemed to be pestering Liu Fei, always by his side. No matter where Liu Fei went, she would follow him. Liu Fei took out his crystal card and unlocked a fist technique martial art. After that, he took it out and took a look. When Liu Fei was engrossed in reading it, Bai Muyun suddenly patted his shoulder.    

    

"What is it?" Liu Fei impatiently asked.    

    

Bai Muyun pointed to a seat beside her, indicating that Liu Fei could sit there and study. What trick is this guy playing again? Liu Fei thought in his heart, but he still walked over and sat on the seat. Bai Muyun smiled as she sat beside Liu Fei and moved closer to him. She peeked at the fist technique book in his hand.    

    

Liu Fei finally understood that this little girl's height could not be compared with his. Just now, she could not see it at all. Now, she lied to him to sit down so that she could see it too.    

    

"You also want to learn fist techniques?" Liu Fei asked.    

    

"Of course not, but it's good to know more. If my enemies happen to know this kind of martial arts, it would be easy to deal with them!" Bai Muyun replied.    

    

Liu Fei nodded and said, "Yes, I did not expect you to have a lot of combat experience." Then he moved the martial art to the side and the two of them looked at it together.    

    

In fact, this martial art fist technique could not even compare to his Fierce Dragon Fist. Liu Fei was just casually looking at it. After all, it was his first time coming to this place. He still didn't know much about this place, but look at the martial arts here. Although he didn't know how to learn this kind of fist technique, it was just as Bai Muyun had said. In the future, when facing enemies, if enemies used this kind of martial arts... He could also easily deal with them.    

    

Moreover, this is a library, so I can study all of the martial arts. When the time comes, I can remember them in my mind, and it can increase my refining of martial arts.    

    

In a short while, Liu Fei had already seen through this martial art with his super strong talent. He then threw this martial art to Bai Muyun.    

    

Liu Fei got up and went to find another martial art. This martial art directly cost Liu Fei five Green Source Polar Crystal, which seemed to be a relatively precious martial art here.    

    

At this moment, Bai Muyun had unknowingly come over. She saw the martial art in Liu Fei's hand and said, "You are really rich! How dare you study this Imperial Soul Formation!" Her voice was a little louder, causing the surrounding people to look over.    

    

The Imperial Soul Formation was a book that explained offensive formations. It was not a pure broken martial art. This attack formation was naturally extraordinary, and it was very useful to Spiritual Core Stage and Earth Core Stage warriors. However, if it wasn't for those warriors who were really studying formations, they wouldn't have paid much attention to it. The materials used to create the formation were extremely expensive, and the attack Array Picture was created by this attack formation. It also consumed a lot of energy, and it was usually used to create an Array Picture. Use it a few times and it's all used up.    

    

Therefore, learning this kind of array formation required those who were focused on studying array formations. Otherwise, if he learned it, he might not be able to display the true power of the formation. If that was the case, then the loss outweighed the gain. Furthermore, five Green Source Polar Crystal were very precious. It was very difficult for ordinary cultivators to accumulate so many Green Source Polar Crystals.    

    

Liu Fei took out the formation book without hesitation. The surrounding cultivators couldn't help but laugh coldly. They knew that it was impossible to learn this formation diagram. In the end, it would only be a waste of crystals.    

    

"What's wrong? Is there anything wrong with taking it?" Liu Fei asked.    

    

Bai Muyun rolled her eyes at him. She thought Liu Fei was pretending to be stupid, but since he had already taken it out, she could not say anything. She ignored Liu Fei and leaned her head over to look at him.    

    

Liu Fei frowned slightly and said, "What are you doing?" This Array Picture was different from the previous martial art. Liu Fei had to study it seriously. Ever since Zhu Yan'er gave him a Hundred-Flower Picture last time, he knew the power of this Array Picture. It could not be underestimated.    

    

Coincidentally, the Hundred-Flower Picture was a defensive formation, and the Soul Controlling Formation was an offensive formation. The two of them could assist each other, increasing Liu Fei's strength by another level.    

    

"What can I do? I can also learn from it. Besides, you're so stupid. If there's anything you don't understand, I can give you some pointers." Bai Muyun's face did not even turn red from boasting.    

    

Liu Fei's eyes slanted slightly and looked at her leader. He said, "No, I need to concentrate. It is easy for me to be distracted if you are by the side."    

    

Bai Muyun directly lifted her head up and said, "Hehe, it's fine. I'll pull it up and you won't be able to see it. This way, you won't be distracted."    

    

Liu Feidao said, "Sorry, it has nothing to do with your small things. I'm not used to you being by my side."    

    

"If you don't show it to me, I will make trouble for you. I will let you see what a disturbance is!" Bai Muyun said.    

    

"Hmm?" Liu Fei did not understand.    

    

Bai Muyun suddenly frowned and covered her stomach. What?" Aiya! You are really annoying. I am already pregnant, but you actually don't want me anymore!"    

    

Liu Fei was slightly stunned. He sneered in his heart. This little girl actually dared to do anything. So he said, "Then continue shouting. It is best to be loud. Coincidentally, I also want a child. If you can't give birth, I can help you again. "    

    

"Get lost!" Bai Muyun fiercely glared at him, turned around and did not look anymore.
