Heaven-defying Upgrade System

Xiao Ruyu's parents did not do anything wrong. It was just a way for them to educate their children. It was also a way to teach them how to survive under the current circumstances.    

    

It seemed that Xiao Ruyu did not know much about the library. After all, it was her first time entering it. However, there were books on cultivation techniques inside. It didn't surprise Liu Fei. The library was just like the library of the major families. Actually, everyone should be able to read the cultivation technique inside, but whether they wanted to cultivate it or not... Whether or not they could cultivate it was a matter of their own.    

    

Xiao Ruyu had also heard about the matter here, so she knew that she needed to buy a ticket to enter. The two of them held the tickets and arrived at the entrance. Just as they were about to enter, Xiao Ruyu's little heart was beating non-stop, and her little face was also slightly red. Looking at the sacred library in front of her, Xiao Ruyu almost started to walk.    

    

Liu Fei had been carefully observing Xiao Ruyu's expression along the way. He saw her look like this. Little girl, if you are interested in cultivation, you can secretly sneak out on normal days. Even if your parents know, what can they do to you?" No parent was willing to hurt their child. Furthermore, Xiao Ruyu's father was so gentle. He should be a reasonable person. Even if he knew about this matter, he would not do anything to the child. It was just that in the future, he might add some more grief. In fact, everyone's parents were like this. When the child understood in the future... They should pay more attention to their parents.    

    

When Xiao Ruyu heard Liu Fei's words, her expression became slightly gloomy. She could not help but sigh, "Sigh, it was easy to say. I want to come here too. But did you know? The tickets here are very expensive. That money is nothing to a rich man like you. But to me, it is a huge figure. The pocket money that my parents give me every month is also not a small amount. Even if I desperately save money, I don't know how long I can save it. Only then can I make a trip here. Furthermore, even if I can come in and flip through the books on cultivation... I can only rely on myself to study those books that I can't understand. Can I really cultivate them?"    

    

As Xiao Ruyu spoke, Liu Fei gradually understood that it was not easy to cultivate in this world. Although their cultivation speed was very fast, if they did not know the cultivation tips, they would probably have to rack their brains and not know if they would be able to cultivate it in the end. To the little girl, it was even more difficult. She didn't have many thoughts to begin with, so she relied on her own comprehension. It was also a fantasy!    

    

However, Liu Fei could tell from this incident that the cultivation techniques in this world were strictly controlled. Even if one could learn cultivation books, if one's comprehension was not high enough... If one could not comprehend the tricks within, it would be a futile effort. At this time, those in the upper echelons would be able to display their abilities. It was to pass on the cultivation experience to these ignorant children.    

    

Thinking of this, Liu Fei couldn't help but think of Si Yin. She had already cultivated to the Spiritual Core Stage. How did she cultivate to this extent? If he made a slight guess, it shouldn't be difficult to guess. Perhaps there was a specialized master teaching her. Or perhaps it could be said that she was trained by the Scouting Group.    

    

The reason Xiao Ruyu's parents were worried about her was not without reason. Once one stepped onto the path of cultivation, what they faced would be one bloody storm after another. The scene of you fighting against each other could be seen from Si Yin's experience. Her life could be in danger at any time. That was why Xiao Ruyu's parents restricted her.    

    

Liu Fei thought for a while. The two of them had unknowingly entered the library. The huge room was filled with cabinets. There were indeed many books in the cabinets. However, the cabinets were locked. And judging from the way the locks were locked, it seemed like there was a restriction placed on them. Liu Fei took a glance and found that the method was very clever. He couldn't break it for the time being, and the only way to solve it was... The key to open the lock!    

    

However, there were free books to read here. Liu Fei roughly swept through them. Most of them were basic cultivation techniques. Most of them were early Mortal Core Stage cultivation books because the people here did not have Body Tempering techniques. They started from the Mortal Core Stage. There were many types of books like this, and they looked extremely complicated. There were all kinds of martial arts and mental cultivation methods, but in Liu Fei's eyes, it was meaningless.    

    

"Let's go somewhere else and take a look!" Liu Fei said and looked at Xiao Ruyu. He found the little girl lying in front of one of the cabinets, looking at the most basic cultivation books and drooling. "It's great to be able to see these things! Let's quickly take it out and take a look!" Xiao Ruyu shouted excitedly.    

    

Liu Fei looked over and saw that it was only the lowest level martial art. Furthermore, Xiao Ruyu looked like she was reading without any foundation. It seemed like this little girl had gone crazy. Liu Fei secretly shook his head. If he let her comprehend and cultivate on her own, he was afraid that it would be difficult for her to enter the beginner level!    

    

Liu Fei wanted to see if there were any martial arts that were worthy of his help here, so that he could see what the martial arts in this world were like. So he pulled Xiao Ruyu up and said, "There's nothing to see here."    

    

Xiao Ruyu widened her eyes and looked at him curiously. "Why is there nothing to see? The things here are all very good. As long as you learn the martial arts here, I will be able to get started! Please let me take a look! " Liu Fei helplessly curled his lips. This little girl must have gone crazy from wanting to cultivate. Although she could also start by relying on martial arts techniques, she did not have a mental cultivation method as her foundation. It was still too early for her to start cultivating!    

    

Liu Fei directly pulled her towards the second floor. There were even more locked cabinets here, and Liu Fei had looked through them one by one from the front of the cabinets. Even low-level cultivation methods were charged, no wonder the people here wanted to learn cultivation methods so hard! There was nothing Liu Fei cared about here, so he directly rushed to the third floor.    

    

"Can I see it now?" Xiao Ruyu asked unhappily.    

    

Liu Fei looked around and found that there were a few high level skills among them. He did not know how powerful this high level skill was. Under Xiao Ruyu's persuasion, he simply opened one of the cabinets and took out a high level skill.    

    

Opening the cabinet required a card or directly throw in a crystal. This was very convenient, he could directly operate it himself. But when he saw the amount of money paid, Liu Fei couldn't help but blink. It actually cost 55 million points, which was 5 and a half Green Source Polar Crystal! It was no wonder that the ordinary people here couldn't learn higher level martial arts. After a slight conversion, it was a prestige value of 55 million, which was comparable to the high level cultivation method in War God Continent. It was indeed a little expensive, but Liu Fei had decided to take a look at the things here. Without any hesitation, he threw five Green Source Polar Crystal inside. After that, he farmed another 500 points.
