Du Feiyun only had four years left, and in these four years, he had to reach the strength of the innate seventh layer and become a true disciple.

Therefore, it was absolutely impossible for him to repeatedly cultivate medicinal herbs, refine pills, and practice in retreat.

He had to find a breakthrough, find a faster and more effective way, get more resources, and increase the speed of cultivation!

It is a good choice to accumulate contribution points by doing sect tasks and exchanging resources from the sect, but the speed is too slow and slow, far from enough for his consumption.

"How good would it be if I could have another adventure like Wu Qianchen and obtain the treasure trove of the ancient great monks? Then wouldn't I have to worry about the magic weapon pill?" Thinking that he was now worrying about the magic weapon, pill and spirit stone and other resources all day long, Du Feiyun suddenly envied Wu Qianchen's good luck.

"En?Treasure Vault?" In his heart, he was fantasizing about what adventures he could get, what treasure inheritance or great monk's treasure house he could get, Du Feiyun suddenly remembered that he had not studied the purple scroll he had snatched in the Underground World Realm.

After he first obtained that purple scroll in the Underworld Realm, that is, the Demon Emperor Catalog, he had always placed it in the Nine Dragons Ding, and he had never checked it. In the past few days, he had also inquired about some news from Ning Xuewei and Xue Bing, and had some understanding of the legend of the Demon Emperor Catalogue.

Xue Bing told him that this Demon Emperor Catalogue was the clue left by the Demon Emperor thousands of years ago, and as long as he collected three copies of the Demon Emperor Catalogue, he could piece together a complete map and find the treasure house left by the Demon Emperor.

There is a treasure that a Demon Emperor powerhouse has scavenged all his life, such a treasure house, if you can get it, how lucky you should be! I'm afraid, when the time comes, it's no problem to treat the elixir as melon seeds, and the magic weapon flying sword as a toy, right?

What's more, there is also the inheritance of that Demon Emperor powerhouse in the treasure house, if you can learn the profound spells and supreme supernatural powers of his inheritance, how powerful would it be?

As soon as he thought of this, Du Feiyun's heart was full of fantasies and expectations, and he was about to drool. He is now poor and white, he is almost out of food, and he can't even sustain the pills, so he is naturally extremely eager to get the treasure house of that Demon Emperor powerhouse.

Since he got a copy of the Demon Emperor Catalogue by chance and had the opportunity to find the treasure house of the Demon Emperor powerhouse, how could he let it go?

As soon as he thought of it, Du Feiyun quickly entered the secret room, ready to study the mystery of the Demon Emperor Catalog.

In the dark chamber, he was on his knees, frowning and contemplating. In front of him, there was a purple scroll suspended in the air, which was the Demon Emperor Catalog.

This purple scroll, which was more than a foot long, had always been rolled, exuding a faint purple brilliance, and no matter how much he tried to get it, he couldn't open it. Obviously, this scroll must have been sealed by the formation.

It's a pity that he studied for a whole day, but he still couldn't figure out the sealing formation of the scroll, and he still didn't have a clue. After all, he has only been in contact with the formation for less than half a year now, and his foundation is very shallow, so how can he crack the formation in it.

"Could it be that you can't enjoy the treasure mountain empty?" Du Feiyun was very depressed when he thought that the clue to the Demon Emperor's treasure house was right in front of him, but he couldn't find the way.

After meditating for a long time, he still couldn't find a way to crack the formation, and Du Feiyun was also very helpless.

At that time, the Duanmu Demon King thought that this Demon Emperor Catalogue had been stolen by Wu Qianchen, and shouted out in public, because now many true disciples and elders in the Liuyun Sect secretly thought that Wu Tianchen had obtained the Demon Emperor Catalogue.

Because of this, Du Feiyun would never reveal the news that he had the Demon Emperor Catalogue to anyone, and it was impossible for him to take the Demon Emperor Catalogue to ask others how to crack the formation. ...,

Xue Bing's attainments in the formation method are very profound, and she should have a way to crack the formation of this Demon Emperor Catalog. It's just that even if Xue Bing had a life-saving grace for him, it was impossible for him to take the Demon Emperor Catalogue to Xue Bing for help.

After all, he already understood the preciousness of this Demon Emperor Catalog, and in his heart it was almost the same as Jiulong Ding, and he was determined not to expose it until it was a matter of life and death.

"Jiulong Ding?" As soon as he thought of Jiulong Ding, a glimmer of light suddenly flashed in Du Feiyun's mind, and he suddenly thought of something, and his helpless face instantly disappeared, showing a hint of joy.

At this time, a trace of thought suddenly appeared in his heart, as if he had found a way to crack the sealing formation of the Demon Emperor Catalog, and he couldn't wait to summon the Nine Dragon Ding.

I saw the Nine Dragons Ding levitating in front of him, instantly changing to the size of a foot, and then, he threw the purple scroll into the Nine Dragons Ding. Next, he moved his mind with his thoughts, activated the formation in the Nine Dragons Ding, and observed the changes in the Nine Dragons Ding with his spiritual sense, and was ready to respond at any time if the situation was not right.

In the Nine Dragons Ding, a certain esoteric and obscure formation was launched under the manipulation of his mind, and he saw countless black lights flashing out, and the Dao Dao Fu Seal characters flashed in the Ding, showing an incomparably powerful power.

The countless flickering black lights enveloped the purple scroll and continued to invade the scroll. Look at it, these black lights are about to decompose and devour the purple scrolls!

The sealing formation of the purple scroll was naturally to protect the Demon Emperor Catalogue from damage, but at this time, it was invaded by black light, and it was immediately activated. Purple light continued to erupt from the purple scroll, and countless rune patterns flashed, and it was the sealing formation that was activated.

The purple light continued to gush out, mixed with the talisman seal and purple light lines, and the black light kept entangled, as if it was fighting to the death.

A quarter of an hour, two quarters of an hour, half an hour......

Finally, under Du Feiyun's mental attention, the purple scroll no longer spewed purple brilliance, and the flashing rune patterns gradually faded. At the same time, the black light in the ding was magnificent, and the swirling black light suddenly rolled towards the purple scroll, intending to devour and decompose it.

"Stop!" At this moment, Du Feiyun shouted loudly in his heart, and under the movement of his mind, the black light suddenly stopped, and then gradually disappeared.

A smile appeared on Du Feiyun's face, and he secretly breathed a sigh of relief, and then opened the Nine Dragons Ding and admitted the Demon Emperor Diagram.

His hands held the Demon Emperor Catalogue, and with a pull of his right hand, he opened the scroll without any delay, and there was no longer any resistance.

"Sure enough!!" Du Feiyun's eyes flashed violently, and his face was full of joy.

At that time, in the Underground World, after killing Qin Shounan, the Nine Dragons Ding Yuan Power was lacking, and it was the best magic weapon that devoured and decomposed him, and the black token left the Yuan Gate, which restored the Yuan power.

At that time, Du Feiyun didn't understand the truth very well, but now he knows the way of the formation, and naturally understands that there is not only the innate true fire array required to refine the pill in the Nine Dragons Ding, but also various auxiliary formations, and at the same time, there is also a devouring and decomposition formation, which can devour the magic weapon to restore the Yuan Force.

Because of this, Du Feiyun put the Demon Emperor Catalogue into it and launched the Devouring Decomposition Array to crack the sealing formation of the Demon Emperor Catalogue.

Now it seems that this plan has indeed succeeded, and the Nine Dragons Ding devoured and decomposed the sealing formation in one fell swoop, breaking the seal of the Demon Emperor Catalog.

The purple scroll was made of some kind of material, like gold and not gold, tough but very soft, purple all over, looking very luxurious. When unfolded, the scroll was more than two feet wide, and it was engraved with patterns and words describing many messages.

After dozens of breaths, Du Feiyun finally finished reading the information on the Demon Emperor's catalog, closed the scroll, and showed a look of ecstasy on his face.

There is no doubt that the information recorded on this scroll is exactly what he expected. ...,

In the scroll, the beginning is a brief account of the life deeds and prominent status and strength of the Demon Emperor powerhouse, and then it is about the many rare treasures, elixirs, and mystical techniques that he collected from traveling the world and crisscrossing the underworld.

According to the records on the scroll, the treasures stored in the treasure house were simply the best in the Underworld Realm, so rich that the ten gates of the Immortal Dao of the Qingyuan Kingdom were coveted.

It's just that the treasure house has to gather three copies of the Demon Emperor Catalogue and piece together a complete map in order to get clues to enter it.

Fortunately, the scroll describes a place in detail at the very end, claiming that it hides a small palace of his, which is also one of his caves.

As long as you enter that palace, you can get a small part of the treasures, although it is less than one-tenth of the treasures in the treasure house, but it is also a large amount of wealth, enough to make the monks of the late stage of the innate and late stage rich overnight!

Originally, Du Feiyun thought that he would still need to work hard to gather three copies of the Demon Emperor Catalogue in order to find the treasure house and obtain many treasures and the inheritance of the Demon Emperor powerhouse. Now it seems that not only that, but before that, you can find his palace first, get a small part of the treasure, and get some sweetness first.

Perhaps, it will take a long time to gather the three Demon Emperor Catalogues, but now he has learned the location of a palace. In this way, Du Feiyun was suddenly even more pleased, and he was bound to get the treasures in the palace.

The treasures in the Demon Emperor's treasury, he can look for them slowly from a long-term perspective. But the palace recorded in this scroll, he must find it immediately. Because the treasures stored in the palace just happened to alleviate his current embarrassment of lack of resources, and it would definitely help him cultivate to the late innate stage faster!

Making a decision in his heart, Du Feiyun put away the Demon Emperor Catalogue and stored it in the Nine Dragons Ding, and soon left the secret room, went to the Hidden Snow Ice Peak, and led the little golden crown eagle out.

Because, it is recorded in the scroll that the palace of the Demon Emperor powerhouse is hidden somewhere deep in the underground world. Next, Du Feiyun planned to enter the Underground World Realm, go to explore the palace, and loot treasures.

Since he had to hurry, and the underground world was extremely vast, he naturally had to use the Golden Crown Eagle to travel, not only was his speed extremely fast, but his own consumption was lower.

Since its hatching, the Golden Crowned Eagle has been in the Hidden Snow Ice Peak, raised by the female disciples under Xue Bing's seat, and consumes a large amount of pills and spiritual materials every day. Normally, it takes five years for the golden-crowned eagle to grow up and take on the task of mounting.

However, Xue Bing learned many secrets from the elders who were in charge of raising spirit beasts, and fed the Golden Crowned Eagle with a large number of pills and spiritual materials, so in just ten months, the little Golden Crowned Eagle had grown up and was already worthy of being a mount.

When Du Feiyun saw the golden-crowned eagle, he suddenly thought that he had seen the mother eagle who did not give an inch and swore to defend the golden-crowned eagle egg in the mountains that day.

At this time, the golden-crowned eagle has grown to more than six feet high, with a golden feather crown on its head, covered with dark and shiny feathers, and the feathers on the edge of its wings are like sharp blades.

What's more, the current strength of this Golden Crown Eagle, which has reached the peak of the Qi Refining Period, can reach the bottleneck, and is only a trace away from advancing to the strength of the Innate Stage.

This discovery undoubtedly shocked Du Feiyun, he didn't expect the strength of this golden crown eagle to progress so terrifyingly. Later, it was only after the introduction of the female disciple that he learned that if the wild spirit beast cultivated by itself, the progress would naturally be extremely slow. However, there are special people to raise them, and they are fed with a large number of rare elixirs and spiritual materials, and the speed of strength improvement is naturally extremely fast.

Moreover, spirit beasts do not have the so-called bottlenecks and shackles like human monks. Except for the two thresholds of the advanced innate and the advanced Dan realm, there are almost no bottlenecks at this golden crown carving, and the progress of its strength is naturally extremely fast.

It's just that what makes Du Feiyun a little speechless is that this golden-crowned eagle is obviously very uninterested in him as a stranger, and only recognizes the female disciple who has been feeding and taking care of him, and doesn't care about him at all.

In desperation, Du Feiyun had no choice but to stay on the Hidden Snow Ice Peak for ten days, and with the help of the female disciple, he fed a large number of pills every day, and then gradually won the recognition of the Golden Crown Eagle.

Ten days later, he finally got his wish and rode the Golden Crown Eagle, left the Hidden Snow Ice Peak, and went all the way out of the Liuyun Sect towards the Underground World...... ，
