Walking into the door of the library pavilion, there was an old man on one side, this old man saw Li Yunfeng's arrival, and there was no change, just muttered, "You need a mortgage on the house number to come to my library to read, when to leave and when to return." ”

Maybe he can see that Li Yunfeng is a newcomer, so he said the rules here, but Li Yunfeng doesn't know about the door number, what is this door number?

But suddenly Li Yunfeng remembered that there was a small rectangular stone in his storage bag, and he didn't feel that there was anything abnormal about him before, but it was given to him by Zeng Mu along with the storage bag, although he didn't care, but now he thought that this might be the so-called door number, so he took out the small stone and handed it over.

The small stone is rectangular and meager with no spiritual power fluctuations on it, and there is no handwriting, but when the old man embedded it on the wall behind him, it emitted bursts of soft light, which was engraved, "Li Yunfeng, the eldest disciple of Chiyun Peak Zeng Mu", although the words are ordinary, but it looks amazing to appear in such a way, Li Yunfeng was slightly stunned, but he did not show much surprise, and then walked towards the hall.

Behind him, the old man's words sounded, "Boy, with your current realm, you can't go up to the reading area above the second floor, of course you can't go up, let's see what you need on the first floor." There is a quiet room next to it, and after finding no one to enter, you can open the guard array so as not to disturb others. In addition, the jade slips here are not allowed to be taken away!"

Li Yunfeng looked back when he heard the voice, and then continued to walk forward.

The old man behind him looked at the direction he left with deep meaning, and then shook his head and continued to look at the jade slip who didn't know what was recorded.

This library pavilion is still very large, and there are many categories of jade slips, which can definitely be described as dazzling, and jade slips themselves also have them, so Li Yunfeng is not much unusual. There are not many people in the aisles, and some people are choosing the books they want.

Formation area, formula area, anecdotal area... Li Yunfeng didn't look at those formulas or formations, but walked to the anecdote area, Li Yunfeng wanted to add some precautions or some other important knowledge in the cultivation realm, which was particularly precious to a rookie in cultivation.

Picking up a jade slip from "Anecdotes of Cultivation of Truth", Li Yunfeng roughly glanced at the beginning, and understood that this was a record of some major events in the cultivation world, so he walked to a quiet room where no one was around.

There was only one futon in the quiet room, an oil lamp behind the door, and nothing else.

There is a spirit stone in each of the four corners, which means that there is a protective array in this quiet room, but Li Yunfeng looked around and did not find any protective array eyes.

In the end, Li Yunfeng froze on the oil lamp behind the door. Walking to the side of the oil lamp, he looked at it carefully for a while, and found that the oil lamp obviously had traces of turning, and then tried to twist it with his hand, and suddenly four light curtains emitted from the four spirit stones, and then enveloped the entire quiet room.

"This array is so magical, but I don't know how powerful it is?"

Li Yunfeng smiled slightly, and then clenched his fist and slammed into the protective array, Li Yunfeng has been practicing since he was a child, although he can't be called innate divine power, but it is definitely not something that ordinary martial arts masters can match, not to mention that he is now a cultivator, let alone the same. But as a result, Li Yunfeng was repelled by the force of the backlash and did not stop until he hit the back wall. I have to sigh, only four spirit stones can achieve such an effect, if this protective array is blessed to a person, then who can break this person's defense.

Li Yunfeng looked at the array for a moment, then sat down cross-legged and picked up the "Anecdote of Cultivating Truth".

"At the beginning of the cultivation realm, it was the name of non-cultivation, called Qi refining, since the beginning of the flood and famine, they are all Qi refiners, who can swallow the sky and spit out the earth, move mountains and seas, and the great power can step on the moon and the sun. ”

"Heaven and earth are unkind, and the common people think that grass mustard will destroy the world overnight. ”

"Then there are people who cultivate the truth, forming the cultivation realm, the cultivation realm is chaotic and warful, and it is divided into three races: demons, demons, and humans, and the three races are all disobedient, and they have conquered each other so far, because the human race is strong, so the world is big with people, and it is difficult to survive in the small night..."

Li Yunfeng looked at it for three days, and at this time he understood that after the great war of more than 100 million years ago, the aura of heaven and earth overflowed, and the aura was scarce, which was no longer suitable for the survival of qi refiners, so the cultivation realm was born, but the people in the cultivation realm were constantly fighting because of various contradictions, and the main contradiction was to compete for cultivation materials, weapons and spiritual energy sources.

Speaking of this aura source, it is divided into three kinds, one is the aura in the air, which is very weak, and even ordinary people can't feel its existence at all, but this aura is the root of the existence of the aura of heaven and earth!

One is the spiritual vein, where there is a spiritual vein, there will definitely be a spiritual eye, but there are big and small. The large spiritual eye can form a spiritual spring, which is completely formed by the rich spiritual energy, so the spiritual energy in it is extremely abundant. The smaller spirit eye is formed by the best spirit stone mother, and this best spirit stone mother will automatically absorb the spiritual energy in the air to form the spirit stone, so the spiritual energy next to it is also very abundant. Speaking of which, it is necessary to explain that the spirit stones are also divided into good and bad, there are lower grade spirit stones, medium grade spirit stones, upper grade spirit stones and best grade spirit stones, a medium-grade spirit stone is equal to one hundred lower-grade spirit stones, and a high-grade spirit stone is one hundred medium-grade spirit stones, and so on. But often in the real transaction, a medium-grade spirit stone can be sold for 150 lower-grade spirit stones or even higher, because the more high-level spirit stones, the more abundant the spiritual energy, the faster the replenishment speed for themselves in the battle between the two sides, so it is often an important item to save life or pursue, and ordinary people are not willing to really exchange it at an exchange rate of one hundred!

There is also Li Yunfeng saw a place that recorded the deeds of Kui Long, Kui Long is the sitting general of the ancient divine beast Feng Qinglong, named after the bloodthirsty torture and killing, in the whole process of assisting Feng Qinglong, he has made countless meritorious contributions and is invincible. But in the end, he died in the eternal war 100 million years ago.

In that battle, Kui Long was killed because of the siege and the oil ran out, but in the whole process, he killed eleven masters equivalent to the Void Breaking Realm, and even killed three scattered immortals who were close to the immortals, and Kui Long at that time was only in the middle stage of the Void Breaking Realm. How can such strength not shock Li Yunfeng!

After these months of cultivation, Li Yunfeng's thinking has become very agile, and the speed of reading is also very fast, which can be described as ten lines at a glance, but the content in this jade slip can not be read in a moment and a half, at this time, his mind is active, and there is not much space in the jade slip that Sister Xin gave herself, so can he use it to rub a copy? It's just that Li Yunfeng really doesn't know the method of rubbing!

Li Yunfeng didn't know how to use the jade slip rubbing, but he tried to use his mind to control the words in the jade slip that recorded the anecdote of cultivating the truth into his own jade slip, Li Yunfeng didn't know the specific method after all, so he could only think of these words into his jade slip out of thin air.

In his mind, he imagined that the words that could appear in his jade slip, but in the blink of an eye, his jade was a flash of light, and these hundred words did appear, Li Yunfeng checked it, none of these words were bad, and even a punctuation mark was correct, Li Yunfeng was very happy, so he tried to move the whole book over, it was very simple.

However, what Li Yunfeng didn't know was the preciousness of a blank jade slip in the cultivation realm, generally even a monk in the Yudan period may not have a jade slip to carry the record, and even if there were, he would not record these cultivation anecdotes like Li Yunfeng, and what Li Yunfeng didn't know was that his jade slip was the only one in this mortal world, and the capacity was so large that it was more than enough to pack all the books on the entire planet.
