After Lin Feng came out of here, he still didn't return to Yaowang Island, but rushed towards Tianyun and the others.

He was going to ask the two of them to see if they knew anything about this parchment scroll, after all, these two people had been in this Heavenly Dragon Sect for much longer than him, and they knew more about it, so maybe they would know the secret of this parchment book.

Lin Feng soon came to the place where the two lived, and with Lin Feng's arrival, the two hurriedly walked out of the room.

"Senior Brother Lin. The two of them clasped their fists in front of Lin Feng and bowed to him.

Lin Feng nodded, didn't drag the mud and water, directly took out the parchment book, and said to the two, "Do you know this book?"

Listening to Lin Feng's words, the two of them looked at the parchment book in Lin Feng's hand, and their brows furrowed tightly.

"Senior Brother Lin, did you take this book in the Library Pavilion?" Yun Dong thought for a moment and said, "Senior Brother Lin, I don't know about this book, I only know that there is not a word on this book, and it is the same for anyone who gets it, as for the rest, I don't know." ”

"Don't you know?" Lin Feng frowned tightly and looked at the parchment book in his hand again.

"Senior Brother Lin, I know something. At this time, Tianyun's pupils shrank, and he said directly, his words full of solemnity.

Lin Cover looked overjoyed, hurriedly looked at Tianyun, and after thinking for a while, he waved his right hand, causing a layer of light curtain to appear in the three of them, wrapping the three of them.

Immediately, Lin Feng hurriedly said, "Say it quickly!"

Tianyun nodded, his face was solemn, and said, "Big brother, in fact, I don't know much, I only know." This book was put into it by the first generation ancestor of my Heavenly Dragon Sect, and I don't know where it came from, but I still know one thing, that is, there is indeed a secret in this book. And this secret, since the founding of my Heavenly Dragon Sect, only one person has seen through it!"

"Who is it?" Lin Feng said hurriedly.

"Medicine King!"

Tianyun said with a solemn face: "Since ancient times, only the Medicine King alone has seen through the secrets in this parchment book! I heard that back then, the Medicine King was simply an ordinary disciple of my Tianlong Sect, and he didn't know how to refine pills at all, but it was because of this book. He became a Dan Dao master!

At that time, this matter caused a sensation in the entire Tianlong Sect, and then, since then, there have been countless people who have borrowed this wordless heavenly book, wanting to become a Dan Dao master like the Medicine King, but. But no one succeeded, no one was looking through the secrets of the book. After a long time, everyone has forgotten about it!"

"Hearing you say that, the reason why the Medicine King was able to become the Medicine King was because he unlocked the secret of this wordless parchment?" Lin Feng's face showed a hint of shock.

You must know that if what Tianyun said is true, then Lin Feng has this Dan Dao foundation in his hand. For Lin Feng, it is extremely important.

After all, the Medicine King just saw through the secret, and he became a well-known and admired Dan Dao master. If Lin Feng also saw through the secrets in this book, wouldn't that mean that he could become a Dan Dao master like the Medicine King?

"Big brother, it should be said that the reason why the Medicine King can become the Medicine King should be the credit of this parchment!" Tianyun nodded.

Lin Feng looked at the parchment book in his hand and fell into silence, and secretly wondered in his heart what kind of existence this parchment book was.

After a while, Lin Feng put away the parchment book and said, "I understand, then I'll leave first, you can wait for my orders here with peace of mind." ”

After speaking, Lin Feng didn't waste time, he directly dispersed the light curtain and rushed out.

At this time, through Tianyun's words, Lin Feng had already made a decision in his heart, that is, no matter what he did, he must unlock the secret in this parchment!

Lin Feng returned directly to Yaowang Island and returned to his cave mansion.

After coming back, Lin Feng didn't study the parchment book first, but took out two storage bags, opened them, and looked inside.

These two storage bags are the storage bags that Lin Feng killed the Blue Bird and Lan Ming, and he hadn't seen what was in the storage bag at that time, so he just went to take a look at it at this time, so he could tidy it up.

There are more than 30,000 qi stones and three spiritual weapons in the two storage bags, and as for the miscellaneous pills, there are also some, but there are not many, obviously, these two people are not very mixed in this Heavenly Dragon Sect.

"There are only 30,000 gas stones!"

Lin Feng looked at the 30,000 qi stones, his face showed a trace of disappointment, and he sighed helplessly, and included it in his Qiankun Ring.

Then, Lin Feng took out the parchment book, put it in front of him, and looked at the parchment book with a frown.

"The medicine king of the year didn't know how to do alchemy at all, but because of this book, he can become the medicine king who is now dominant, it seems that this book contains a big secret about Dan Dao, as long as it can be solved, I am very likely to become the same medicine king as him, but what is the secret in this book?"

Lin Feng looked at the parchment book in front of him and fell into silence, guessing in his heart what the secret in this parchment book was.

After a while, Lin Feng didn't come up with a reason, and said to himself: "You can't think like this, you have to try little by little." ”

Immediately, Lin Feng's right hand was raised and placed on the parchment, and the yin and yang qi in his body suddenly trembled, released through his right hand, and teleported towards the parchment.

With this teleportation, Lin Feng found that after his yin and yang qi entered this parchment book, it did not cause any abnormalities at all, as if this parchment book was an extremely ordinary book, and there were no secrets hidden in it at all.

Lin Feng took back the yin and yang qi, and after thinking for a while, he picked up the parchment book and put it on his heavenly spirit cover, wanting to see if the parchment book was the same as the jade plate.

However, there was no response.

Then, Lin Feng slashed his hand away, causing blood to flow out of it and drip on the parchment.

After Lin Feng's blood dripped onto it, it condensed but did not disperse, and slipped directly to one side.

"You can't use qi, you can't put it in the Heavenly Spirit Cover, and you can't drop blood, what should you do?" Lin Feng frowned and fell into silence again

Time passed slowly, and more than ten days passed in a blink of an eye, and in these more than ten days, Lin Feng had been pondering, it can be said that he had thought of countless methods, and even, Lin Feng had used fire, Yin and Yang Qi to attack, and stabbed with the Overlord Gun, but no matter what he did, he couldn't destroy this parchment.

But the result was the same, he still didn't discover the secret in the parchment.

However, Lin Feng was not angry, and he did not give up, because he knew that if the secrets in this parchment could be seen through so easily, it would not be his turn, and I am afraid that countless people would have already seen through the secrets in this parchment.

"How can the secret in this parchment be solved?" Lin Feng looked at the parchment in front of him and fell into silence again.

After this period of research, he felt more and more that this parchment was not simple, and the more he wanted to unlock the secrets in this parchment

Time passed slowly, and a month and a half passed in the blink of an eye.

At this time, Lin Feng was disheveled, his eyes were red and bloodshot, and his expression was a little crazy.

"What is the secret in this parchment?" said Lin Cover, a hideous self-expression.

In the past month and a half, Lin Feng has never rested, and he has been thinking about any way to unlock the secret in this parchment, even he feels a little physically and mentally exhausted at this time.

"I won't give up, I must solve the secret in this parchment!" Lin Cover's face was hideous, his eyes revealed a look of madness, and he had no intention of giving up.

He has now spent nearly two months studying this parchment book, these two months of time, he will not waste it in vain, if he does not unlock the secret in this parchment, then he will lose, and Lin Feng is a person who will never suffer.

Moreover, Lin Feng is also a person who admits death, he has already decided in his heart that he wants to study the things in the parchment, if he does not study it, he will never give up.

Suddenly, at this moment, Li Yan'er's figure rushed in directly from the outside.

I saw that at this time, Li Yan'er was embarrassed and haggard, obviously, in the past two months, Li Yan'er had worked hard to refine the pill for Lin Feng.

Li Yan'er looked at Lin Feng's appearance in front of her, and then glanced at the parchment book in front of Lin Feng's cover, and immediately understood, and then shook her head helplessly, as if she vetoed Lin Feng, thinking that Lin Feng couldn't see the secret in this parchment book.

Lin Feng was still thinking about the secret of the parchment book wholeheartedly at this time, and he didn't pay attention to Li Yan'er's arrival at all.

"Lin Qi!" Li Yan'er looked at Lin Feng and didn't notice her arrival at all, and shouted to him.

When Lin Feng heard Li Yan'er's words, he also reacted, and looked up at Li Yan'er.

When Lin Feng saw that it was Li Yan'er, his face suddenly became happy, and he hurriedly stood up and said, "Senior Sister Li, I heard that the secret medicine king in this parchment book has been cracked, Senior Sister Li, I don't know if you know, what is this secret?"

At this time, Lin Feng's mind was full of the secrets on the parchment book, and the moment he saw Li Yan'er in front of him, he instantly remembered what Tianyun had said to him, saying that this parchment book medicine king knew the secret, so Lin Feng was wondering if this Li Yan'er also knew the secret.

As for the matter of controlling the life seal in his body, at this time, Lin Feng had completely ignored it, that is, he had forgotten the purpose of Li Yan'er coming here. (To be continued......)
