When Pei Feng heard this, he couldn't help but smile awkwardly, but fortunately, he had his back to Ouyang Cheng, so he wasn't afraid that Ouyang Cheng would see something.

"Brother Ouyang, wait a few more days, and when Elder Zi returns, I will go with Brother Ouyang to visit the elders in the sect. ”

But Ouyang Cheng shook his head and walked in front of Pei Feng: "Brother Pei Feng, but the elders in the sect have already urged me many times, if I don't go, I'll be on a bad deal!"

Pei Feng faintly sensed a hint of something wrong from Ouyang Cheng's tone, under normal circumstances, Ouyang Cheng should not have forced him like this.

"Did he find something?"

"No, I didn't show any flaws, could it be some other reason I don't know?"

After thinking about it for a while, Pei Feng couldn't think of a reason, so he had to deal with it first: "Brother Ouyang, I also understand your difficulties. However, Elder Zi explained that I was not allowed to leave the sect until she came back, and I asked Brother Ouyang to forgive me. ”

Of course, Elder Zi didn't say such a thing, but Pei Feng was not afraid of being exposed, could it be that Ouyang Cheng dared to confront Elder Zi face to face?

A trace of doubt flashed in Ouyang Cheng's eyes, but he couldn't find any reason to continue persuading, so he asked unwillingly, "Did Elder Zi say when he would come back?"

"It's coming, I should be back in a few days. ”

In fact, Pei Feng didn't know how long it would take for Elder Zi to come back, but the important thing was that in a few days, the items sent by Yun Chang should have arrived.

At that time, he will go with Ouyang Cheng, so what's the matter!

"Okay, when Elder Zi comes back, we'll go visit the Sect Elders!"

After the two agreed, Pei Feng immediately rushed to the library pavilion.

It's just that when Pei Feng left, Ouyang Cheng took out a sound transmission jade pendant from the storage bag, and after sending out a message, he stood in place and pondered.

"Could it be that Elder Zi's matter really has nothing to do with him?"

But after thinking about it for a long time, Ouyang Cheng couldn't figure it out, but if Pei Feng and Elder Zi were really involved, he could only kill him!

After Pei Feng came to the library pavilion, he walked directly to the innermost part of the first floor, where the stairs leading to the second floor were located.

"Tokens!"

A disciple on duty on the side of the stairs saw someone coming, so he immediately stepped forward to ask.

Pei Feng did not hesitate and handed over the token in his hand.

After checking it, the disciple on duty returned the token to Pei Feng: "Go over!"

When Pei Feng came to the second floor, he found that there was a door blocking it. It took him a moment to react and place the token in the groove in the door, and the door opened.

There are not many people on the second floor, probably less than half of the first floor, so it feels a lot empty at a glance.

Pei Feng quietly walked up to an old man and bowed respectfully.

This person is the manager of the second floor of the library, and he is resting in a rocking chair.

The old man didn't speak, just smiled at Pei Feng, and then motioned for Pei Feng to give him the token.

Pei Feng was stunned at first, but he didn't ask, and handed the token over directly, he could see that the old man didn't want to speak.

After a while, the old man returned the token.

After Pei Feng took it, he probed his divine sense into it. It was found that there was an extra list in the token, and the books on the second floor of the library were all on it, and the location was also marked.

This undoubtedly provided great help to Peifeng, after all, it was extremely difficult to find the one Peifeng needed among the countless books.

Pei Feng glanced at it, and immediately found the book he wanted, and after bowing heartily to the old man, he quietly walked away.

Pei Feng followed the instructions in the token and walked over to a row of bookshelves and gently pulled out one of the books.

The book is called "Destruction Dan Dao", and it looks extremely new, and it doesn't look like it was left by Danwu's predecessors at all.

But Pei Feng understands that this is not the case. It should be that this book is too out-of-the-way, and no one even cares about it, so it will be like this.

Pei Feng did not rush to copy the book into the Demon Clan's secret book, but opened it directly and savored it carefully.

After all, reading at home and reading in the library are two different flavors.

The beginning of the book is not related to alchemy, it is the cause and effect of Danwu's predecessor's discovery that the destruction attribute can be alchemy, and why he wrote this book.

Danwu seniors are different from Pei Feng, he joined the Hundred Refining Sect very early, but at that time, his alchemy talent was pitiful, and after cultivating in the sect for a year, the success rate was not even one-tenth.

It's just that by chance, he accidentally comprehended the destruction attribute, and he also discovered that the destruction attribute can be used for alchemy, which made him extremely excited!

But soon, he was disappointed again.

Because although it can be 100% pilled, the quality of the pill is pitiful, and even some of them are poisonous pills, so they can't be taken at all.

Under normal circumstances, Danwu seniors would give up alchemy with the destruction attribute and return to normal alchemy methods.

But he didn't.

Because he knows that his alchemy talent is really pitiful, and if he follows the rules, he is afraid that he will do nothing for the rest of his life.

He was not convinced!

Why!

He asked himself, he Danwu would not lose to anyone!

He decided to delve into the method of using the destruction attribute alchemy to create a precedent in the alchemy world!

So, after consulting countless classics, borrowing from the alchemy techniques of countless predecessors, it took a whole decade to finally develop a method of alchemy with the attribute of destruction, called the Dao of Destruction Dan!

In the end, the Danwu predecessors also relied on this Destruction Dan Dao to become famous, defeated countless alchemy powers, and became a unique giant in the alchemy world!

After Pei Feng finished reading the preface, he closed the book and held it in the palm of his hand to show his respect for Danwu's predecessors.

Danwu's predecessors can rely on their own strength to create the world-famous destruction Dan Dao, undoubtedly a person with great determination and perseverance, and in the end, he also said that this destruction Dan Dao is open, such a person is worthy of cultivation.

It took a long time for him to calm down the excitement in his heart, and slowly opened the book again, looking at the text of the book.

After a few hours, Pei Feng finally finished reading the text.

Originally, he could use the Demon Secret Book and directly copy the book into his mind.

But Peifeng didn't want that.

This is disrespectful to Danwu's predecessors, and disrespectful to the results of his painstaking efforts!

Pei Feng still wanted to rely on his own ability to seriously learn this Destruction Dan Dao, and at the same time, he could also feel the convincing personality charm of Danwu seniors!

The principle of destroying the Dan Dao, Pei Feng also roughly understood.

The quality of the pill was very low after Pei Feng became a pill before, and it turned out that his method of absorbing the destruction attribute was wrong.

The method of collecting pills is to remove the destructive attribute in the pill, but Pei Feng has the destructive attribute, and it seems that there is no need to collect pills, which is actually wrong.

The ordinary method of collecting Dan not only has to remove the destructive attribute, but also has to follow a certain rhythm and a certain rhythm, which seems to contain some kind of avenue, and Pei Feng can't understand it for the time being.

Therefore, even if Pei Feng has the attribute of destruction, he can become a 100% Dan. But if you want to improve the quality of the elixir, you must abide by this rhythm, and the more you fit with this rhythm, the higher the quality of the elixir.

Before cultivating the wind, the alchemy was to directly absorb the destruction attribute at once, and there was no rhythm at all, so the quality of the pill was pitiful.

Pei Feng let out a sigh of relief, and after understanding what was going on, he wanted to immediately return to the alchemy release and test this method.

But he flicked it lightly, and the book didn't seem to be finished, and there seemed to be content to come.
