Hao Yun decided not to talk about these secret things tomorrow night, and it doesn't have much to do with him now, so he still wants to think about how to upgrade is a big deal. When I see Elder Fang tomorrow night, I will directly ask him for exercises, and if he can't do it, I will go to the Fang family's library to find it.

The next day of class, Mr. Feng sent the materials down and officially began to explain to them, and soon Hao Yun was not interested in listening, it was not a way at all, and his current situation was completely inapplicable.

In the evening, Hao Yun came to Fang Lao's residence, but Fang Lao had not returned, so the servant took him to the study and asked him to wait here.

Hao Yun had nothing to do, so he ran to the bookshelf to see what books were available. In the spiritual world, most books are idle books and are useless, sometimes only used as a kind of decoration, after all, paper books are not easy to preserve, and the amount of information is also small, so the real carrier used to record information in the spiritual world is book jade, a kind of jade that has been refined by practitioners, and the shape is generally made into a jade simple shape.

The advantages of this jade slip are much better than the paper book, first of all, due to the different ways of recording, you can use your divine sense to browse, this is much faster than the paper book with visual viewing; secondly, the preservation time is long, it can be said that as long as it is not deliberately destroyed, it is difficult to break the jade slip, after all, it is also refined, it is still very strong, and it also has the characteristics of high temperature resistance and corrosion resistance; finally, it can be encrypted content, and it is difficult to browse, copy, modify and other behaviors.

For example, Hao Yun's family heirloom is a jade slip for encryption, and if there is no correct decryption method, it is impossible to see the actual content.

If you want to say what are the disadvantages of jade slips, that is, the production cost is relatively expensive, the price of blank jade slips varies according to different capacities, the larger the capacity, the more expensive, and it is not a linear increase, that is, the jade brief with the content of 2 books is more than 3 times more expensive than the jade with the content of a book, and the higher the capacity, the more expensive the price, so it is basically difficult to make a jade slip contain the content of thousands of books.

In addition, the content of jade slips must be recorded by professional book makers, not that anyone can record the content, so the recording cost is much more expensive than that of printed books. In the same way, if the content of the jade slip needs to be changed or added, it needs to be completed by a professional book maker. Generally, after a jade slip is recorded, because the soul frequency of different book makers is not the same, so when modifying and adding operations, you must find the book maker at that time, if the book maker dies and other reasons cannot be found, the content of this jade slip cannot be changed.

Due to the existence of jade slips in the spirit world, Hao Yun did not have any hope, and wanted to find something useful from the large pile of paper furnishings and books on the shelves.

Hao Yun casually took out a book from the shelf, the title of the book is quite attractive to him, the book is called "Decrypting the Origin of the Demon Race", this kind of decryption books have always been his favorite, although most of them are serious by the authors, but he still admires these authors' brains, and they give you a round in a matter, there is still some truth.

The author of this book is really powerful, and it is written in the book that demons are produced by human beings, and to put it bluntly, they are demonized people, and demonization is a process of demonic corrosion. So where did the demonic qi come from? The book boldly speculates that the demonic qi is likely to overflow from the Southern Spirit Realm to the legendary Demon Spirit Realm. As for why the demons are destroying the human world, it may be because the evolution of the demons requires the power of the human mind, and the humans who have captured their hearts will become demon servants, and at the same time, they will feed back the power of the master, so that the demons will grow, the more powerful the demons, the more his demon servants, and the greater the power of the demon servants, the stronger their masters will become, so after the strength of the demons reaches a certain stage, ordinary people will not have much effect on it, so the demons will find cultivators to capture.

Hao Yun stood by the bookshelf, looking at it with relish for a while, suddenly the door opened, Fang Lao walked in, saw him reading a book in his hand, and said with a smile: "You kid is still interested in the books published by the other party, I see that you seem to be quite addicted!"

Hao Yun smiled: "The writing is good, the brain hole is very big, your Fang family still has this hobby, look at this bookshelf is quite big, but a lot of books have been written! I don't know, who wrote this book from the Fang family?" Hao Yun casually handed the book to Fang Lao, who came to him.

Fang Lao picked up the book and looked at the title, obviously with a very surprised expression, Hao Yun was a little strange, and asked, "Is there any problem?"

Fang Lao put the book back on the shelf, beckoned Hao Yun to sit down, thought for a moment and said, "The author of this book is signed by my pen name, but the content is not written by me, which is also something I can't figure out. ”

Hao Yun thought to himself, what is this, other people's things are occupied by you, taking advantage of them and selling them. "What's going on? Master. ”

Elder Fang continued: "The content of this book was provided to me by Lord Lingdi, and I asked me to find a book club to publish it, and I can't use his signature, so I will use my pen name to publish it. I have also read the content of this book carefully, although it looks a little absurd, but thinking that it was provided by Lord Lingdi, it must not be written blindly, but if it is true, why does Lord Lingdi not use his own signature, so the influence is completely different. In this way, the high-level of the spirit realm can be called on to use troops against the southern spirit realm, investigate the cracks, and finally seal the place where the demonic qi overflows, and completely solve the problem of the demon race once and for all. ”

Hao Yun thought to himself, this is a way, it seems that there is a hidden secret. But what does this have to do with me? The main purpose of this time is the Five Elements Exercises, and nothing else can be done.

Hao Yun thought of this and hurriedly said: "The problem of the demon race, let's let it go first." Master, the most important thing for the apprentice now is to break through to the Jindan stage! After I took class today, I have already determined that the current set of single-attribute Five Elements exercises is not suitable for the apprentice. ”

"Oh, that's right, speaking of which, what kind of cultivator are you now? I don't think it's just fire and water. ”

Hao Yun knew that now was not the time to hide it, so he replied very simply: "Report to Master, the disciple is a five-line cultivator with all five elements, and it is estimated that he is the first one in the spirit world!"

Fang Lao was not surprised, and touched his nose: "Sure enough, you kid is too greedy, this is not easy to do! The Fang family's collection of exercises is also rich, the problem is that the exercises of the two and three systems can barely be distinguished, and your five series is more difficult." By the way, the main technique of the Fang family is called the art of light, this attribute does not belong to any of the five elements, and the attribute of our cultivation is called time. ”

Hao Yun's body was shocked: "Damn, such a cow! It turns out that there are other attributes in the spirit world, I have always thought that the spirit world only has the five elements of spiritual power, but the attribute of time, how should I cultivate? Master, do you think I have changed the art of light, how can the Five Elements Exercise have a future in the time exercise, not to mention that the Fang family's time exercise is still up to the sky." ”

Fang Lao quietly looked at Hao Yun, who was gushing because of excitement, and Hao Yun slowly noticed it, so he stopped talking.

Elder Fang sighed: "The Technique of Light is too difficult, why do you see why Master looks so old? The actual age of Master Wei is not a few years older than Master Pan, but they look like middle-aged people, and I am an old man." This is because the biggest problem with the Light Technique is that cultivators have a short lifespan, and they must cultivate to become immortals during their lifespan, but their lifespan is short, so there are far fewer people in the Fang family who can succeed than other families. At least as a teacher, he currently has no confidence in being able to cultivate into an immortal. ”

Hao Yun looked at the white-haired Fang Lao, speechless for a while, he didn't practice such a cow's exercises, he was so sorry for himself, maybe he was a genius.

"The most important thing is that cultivating the exercises requires the spiritual power of perceiving time, don't worry about deciding what to practice, you can ask for leave in the past two days, I will take you back to the Fang family, the Fang family is also relatively close to the spiritual capital, and it just happens to introduce the important clansmen of the Fang family, after all, you are also the only person with a foreign surname who has entered our Fang family in the past ten years. "Elder Fang directly arranged it for Hao Yun.

Hao Yun was overjoyed: "Thank you, Master, the disciple will go back to Fang's house with you, and he will behave well, and he will not embarrass the master." ”

Elder Fang said angrily: "You kid just save it, Master's old face is not afraid of losing it, important things, solve your problems, otherwise it will be called a shame, and accept a disciple who will build a foundation forever." When you say that, isn't Master going to clean up the portal?"

Hao Yun was kicked out by Fang Lao, returned to the dormitory, pressed his excited heart, and hurriedly contacted Teacher Feng to ask for leave, and after getting an agreed reply, he thought about it and sent a message to Dahai and Quartz Sword, telling them to go to Fang's house in the next two days.

Hao Yun decided to go to Fei Fei's dormitory in person to tell her, Fei Fei was not surprised by his visit, the two talked about what happened these days, it turned out that Fei Fei and they were already preparing to break through to the Jindan period, her master promised to wait for her to complete the breakthrough, take her back to the headquarters of the Chamber of Commerce, to meet the senior management of the Chamber of Commerce, and at the same time look for prosthetic materials to help her reshape her right arm and right hand. Hao Yun promised that he would solve the problem of the exercises as soon as possible, and it would be best if he could come back to see her off when she left the academy.

After a while, Fei Fei pushed Hao Yun out of her dormitory and asked him to hurry back to rest, and he would not be sent to class tomorrow because he had to go to class. Hao Yun stood in front of the door of Fei Fei's dormitory, suppressed the strong desire in his heart, and after his body slowly returned to normal, he sighed faintly, turned around and walked in the direction of his dormitory.
