Lin Fangtian nodded, and said with some joy: "No problem, let's start now." ”

"Hehe, in that case, I won't bother you. As he spoke, Fauber walked out of the secret room, and the moment he walked out, the row of bookshelves closed automatically, and there was nothing strange in them.

Lin Tao looked up at the roof of the secret room in a little surprise, his eyes were full of strangeness.

As if he saw Lin Tao's thoughts, Lin Fangtian smiled and said, "This secret room was built by your grandfather with great efforts to find the greatest craftsman in the empire, and there are not a few tricks in it. This secret room uses a vacuum hybrid structure, so even if something big happens in the secret room, and there is no loud sound, people outside can't hear it, even if it's next to the bookshelf. Lin Fangtian's expression was full of pride, "If my guess is correct, you must be curious about why the space in this secret room can't be seen from the outside of the study." If someone observes the study in the courtyard, they will not find that there is a hole behind the study, because from there, the study has occupied the entire space, so where is the space of the secret room? ”

"That's because the periphery of the entire study uses a kind of paint used by the dwarven master craftsmen to build the palace for the king of the dwarf race, this paint is very magical, it can cover the color of the object itself, and at the same time it does not have any color, coupled with the blind corner of people's vision and the combination of light and dark, the space where the secret room is located cannot be seen from the outside of the house. Actually, it exists, but it can't be seen. ”

After Lin Fangtian's explanation, Lin Tao had a general understanding of what was going on, and it turned out that he had used means in paint. Let him still think that this secret room is a mustard seed space as Quan Qingzi Lao Niubi said, but then he thinks about it and feels that his idea is really ridiculous, this world is still worse than Kyushu, and that kind of space magic power should not exist.

I saw Lin Fangtian's hand shaking slightly, and when he said goodbye, there was already an extra piece of parchment with a small area in his hand, and he shook it casually, but Lin Fangtian threw the parchment in his hand to Lin Tao.

Taking the parchment, Lin Tao glanced at the content on the parchment, and suddenly his expression moved, and he said in surprise: "This is "Nine Dragons Change". "As far as I can see, I don't know how many years have passed on this parchment, and the black handwriting on the paper is slowly fading in some places. If you must know that the handwriting left by a good parchment is not so easy to oxidize, unless it is too old, you can imagine the history of this parchment.

It was cold at the beginning, Lin Tao suddenly felt that the whole person seemed to relax in an instant, his heart was calm, he didn't make waves, he looked at Lin Fangtian a little strangely, and said the curiosity in his heart.

"I don't know exactly what it is, even your grandfather can't tell. Probably the ancestors cast some kind of powerful elven spell on the parchment. You must know that the magic power of the fighting god is definitely not something you and I can imagine. ”

After roughly browsing the content recorded on the parchment, it was not jerky and difficult to understand, and Lin Tao was also a little relieved. Unexpectedly, Lin Fangtian's voice sounded again, "Don't underestimate "Nine Dragons Change", and don't be confused by the superficial phenomenon. You must know that "Nine Dragons Change" itself is one of the few basic saint-level secrets on the Izumo Continent, and it can be used as a saint-level secret, and the difficulty of it can be imagined. As far as I know, among the other basic saint-level secrets on the continent, the royal Richards family of the empire should have one, and secondly, the dwarven patriarch should also have one, and the last one is unknown, it may be the beast clan, or it is more likely to be ......" Speaking of this, Lin Fangtian's face changed, and his voice stopped abruptly.

Lin Tao didn't notice the change in Lin Fangtian's face, and his mind had already sunk into the words that were old but rushed to the breath of strength......

"Besides, if 'Nine Dragons' Change is really so easy to cultivate, my Lin family may not be what it is today. Since the unknown for a long time, the Lin family has always been a single lineage, and there will be no other heirs in addition to this, which is a very strange thing in itself. Over the years, there have been many talented descendants of the Lin family, but very few people have been able to succeed in cultivating the "Nine Dragons Change", even your grandfather has only only cultivated to the fourth change, and he can no longer cultivate. ”

"Then how many changes have you cultivated?" Lin Tao asked curiously.

Sighing, Lin Fangtian said, "I have only cultivated to the third change. Suddenly, the words changed and continued: "Don't underestimate this third and fourth change, you must know that even if your grandfather only practiced the fourth time, he had enough strength as a great fighting master, although he was not outstanding in the entire continent, but he was also a character, not to mention what kind of shock it was for those generals on the battlefield who marched and fought to have such fighting strength." ”

Lin Tao smacked his tongue slightly, thinking: "Only the fourth change has the strength of a great fighter, so what about the fifth change, the sixth change, and even the final ninth change." The surprise in Lin Tao's heart can be imagined, and he inevitably looks forward to it.

After a pause, Lin Fangtian's voice was still calm: "The weirdness of "Nine Dragons Change" is the word 'change'. In fact, there is no difficulty in the cultivation itself, and it can even be said to be quite simple, as long as the savings of the fighting spirit reach the standard, there is no need to worry about going crazy at all. Perhaps the difficulty of cultivation has already been integrated into the difficulty of the advancement, resulting in incomparably difficult every advancement, not only the torment of the body and mind, but also the re-training and sublimation of the body, perseverance, and spirit, and the difficulty can be imagined. Of course, the benefits brought by each change are also extremely amazing, and the tremendous transformation of intelligence, body, strength, fighting spirit, and mind has soared. ”

Hearing this, Lin Tao looked at Lin Fangtian in great surprise, "It's so amazing, can cultivation exercises still improve people's mind and intelligence?" Lin Tao's surprise can be imagined, you must know what an existence against the sky, the huge improvement in strength is already unimaginable to many people, and now it is accompanied by the sublimation of intelligence and heart. In other words, the more "Nine Dragons Change" cultivates to the end, the smarter it becomes, and the more mature its mind becomes.

Lin Fangtian glanced at his son angrily, smiled and nodded.

"Then what is the difficulty of the advanced level that you said, father?" Lin Tao asked.

"Because every change needs a guide, and there are many things that guide it, but the crystal nucleus of the Warcraft can be a panacea, it can be anything of value. But the only thing that remains the same is that the value of the guide items required for each change is definitely much more than the guide items for the previous change. For example, the first change to advance the second change may only need a third-level Warcraft crystal nucleus is enough, but the second to the third change requires a sixth-level or even seventh-level Warcraft crystal nucleus, and the third to fourth changes will require the crystal nucleus of the ninth-level Warcraft......" In the end, Lin Fangtian's voice became smaller and smaller, and only those who had cultivated knew the difficulty of this.

What kind of existence is that? It is equivalent to the existence of a Dou Sheng, even more powerful than a Dou Sheng, you must know that many powerful Demonic Beasts themselves have all the rare talents, some have strong vitality, and some have unmatched defense, these are all racial advantages, and they are definitely much stronger than the human Dou Sheng. "Back then, your grandfather was also extremely lucky, with the cooperation of most of his subordinates, he killed that ninth-level demonic beast, and the demonic beast itself seemed to be seriously injured. But even so, your grandfather's side paid for dozens of lives. ”

Lin Tao listened bitterly, only felt that this "Nine Dragons Change" exercise was really a bit perverted, the third change advanced and the fourth change was so difficult, what about the fourth change and the fifth change? I'm afraid it will be a twelfth-level Warcraft, it doesn't seem that there is such a powerful Warcraft, and the strongest is only a tenth-level Warcraft, which is equivalent to the existence of a fighting god in the human world. Although it can be replaced by other real rare items, its rarity is probably about the same as the degree of difficulty in obtain.

Sighing, Lin Tao didn't know what it was like in his heart. The holy book is the holy book, and it is indeed not an ordinary vindictive secret that can be compared, and even those vindictive secrets are difficult to match. But the difficulty of this cultivation has also increased exponentially. Advancement is not only enough by perseverance and talent, but also by luck, money, and so on.

Exhaling a deep breath, Lin Fangtian expelled the depression in his heart, after all, his current strength had reached the peak of the third change, but he was helplessly stuck by the guide item of the fourth change. As far as I can see, I really can't take out anything with unusual value, especially precious and containing energy.

"Okay, from today onwards, you can start to practice the first change of the Nine Dragons, you can put down the work of boiling your body for a while, you only need to exercise a little every day, and then you have to spend all your energy on cultivating the first change. Looking back at the surroundings of the secret room, "You are no longer suitable to stay in the Yanwu Hall to cultivate, and this secret room will be handed over to you from today on." Here's the key. With that, Lin Fangtian threw Lin Tao a spherical stone.

Lin Tao took it and looked at it carefully, this stone was about a quarter the size of a palm, crystal clear, and there were two special lines at both ends of the ball, thinking that it was already some kind of mechanism that touched the door of the bookshelf.
