Return to the Dragon Palace.

The first thing Wang Yan did was to take the group to Priest Chengyu's residence, and Priest Chengyu seemed to know that they were coming to him, and opened the door at the moment when Wang Yan was about to knock on the door.

Seeing that there was only a pair of tables and stools and a wooden bed inside, without any other decorative items, for the dragon clan who naturally loved to collect treasures, this house layout formed a strong contrast, it was hard to imagine that this was a room where a priest lived, a priest with monstrous power, and the dragon king of the real dragon clan had to obey the proposal of the priest Chengyu.

"Sit down, you all know, I'm here to ask something. Priest Chengyu invited Wang Yan and the three of them into the room.

After the three of them sat down, Priest Chengyu personally picked up the purple sand teapot on the table and poured tea for the three of them.

Seeing Priest Chengyu's action of pouring tea, Wang Yan immediately got up and wanted to take the purple sand teapot in Chengyu's hand and show them the tea himself.

"It doesn't matter. Priest Chengyu motioned for Wang Yan to sit down and filled the teacups in front of him one by one.

Priest Chengyu picked up the teacup and took a sip before speaking: "Take out the things, I want to see them too." ”

Wang Yan carefully took out the black stone wall from the auction and the mysterious book from the space bracelet and placed them neatly in front of the priest Chengyu.

Chu Er and Xiao Mo'er looked at Priest Chengyu with a glint in their eyes, their curiosity was also very great, and they were eager to know whether these two items were a mysterious treasure, especially Xiao Mo'er, which he had discovered, so he was even more sad, and the look of anticipation in his eyes was about to come out.

Priest Cheng Yu's right hand gently rubbed the entire black stone wall, a look of surprise flashed in his eyes, and then returned to normal.

The black stone wall that had been rubbed did not show any abnormality, and it was still lying quietly on the table.

Priest Chengyu smiled: "Wang Yan, you have picked up a big bargain this time. ”

Wang Yan's heart stabilized when he heard this, since the big bargain that Cheng Yu Priest said in his mouth was definitely a treasure of not low grade, this black stone wall was like this, then the mysterious book next to it was naturally not bad, he was more concerned about some things about the mysterious book, and this book had always had a weak sense with him.

Wang Yan still asked Priest Chengyu in a slightly nervous tone, "What kind of treasure is this black stone wall?" ”

Priest Chengyu stroked the short beard with his hand, and sold a pass to Wang Yan: "You can guess, make a bold guess." ”

Wang Yan didn't know how bold this boldness was, and after thinking for a while, he tried to say the answer in his heart to Priest Chengyu: "First grade artifact?"

The first grade of the artifact and the Upper Evil Sword he is using now are the same grade, and he thinks that he can have a rating with his Upper Evil Sword, and his guess is already bold enough.

When Priest Chengyu heard the answer, he smiled and shook his head slightly.

Chu Er and Xiao Mo'er next to them all gasped, the artifact was not at the beginning, could it be higher, this was something they couldn't imagine.

Xiao Mo'er hurriedly got up and stood on the ground, her face had already turned red with excitement, and her excitement made him forget the size of his voice, "Is it a medium-grade artifact?"

Fortunately, no one else remembered the location where Priest Chengyu lived, otherwise Xiao Mo'er's loud voice would definitely have been heard by them.

Priest Chengyu shook his head again.

This shaking of the head actually made Wang Yan and the three of them feel that they couldn't breathe, as if a big mountain was pressing on their chests, and this big mountain was the answer to the black stone wall grade.

You must know that the superb artifact is about to become extinct in the world, and those races that have the superb artifact will not take out the superb artifact and use it until they are about to be wiped out.

Even if it is a high-grade artifact, it is a rare existence, as far as Wang Yan knows, the fundamental treasures of the Tianyu Clan's Tianling Bead and the True Dragon Clan's True Spirit Bead are only high-grade artifacts, and the Dream Spirit Bead in his hand He doesn't know what level it is, thinking that the grade is not low, but he is not sure about the specific level.

Priest Cheng Yu looked at the three of them with surprised faces, and said with a slight smile: "I'll tell you directly, and your guess is right, this black stone wall is a high-grade artifact, so I will let you guess boldly." ”

Although they heard Priest Chengyu admit it personally, Wang Yan and the three of them still did not wake up from the shock.

The high-grade artifact was auctioned for only 200,000 spirit coins, but it was not as simple as picking up a bargain, it was simply a burst of luck.

Priest Cheng Yu continued: "But there is a premise for using this black stone wall, that is, you must first learn the exercises on this book, otherwise this black stone wall is no different from ordinary stone walls, I guess the person who owned this treasure before will definitely not be able to use this treasure to use it for auction, if Wang Yan you can't learn the exercises on this mysterious book, you will be useless if you auction him over." ”

Wang Yan glanced at the mysterious book that was still quietly displayed on the wooden table, and the vague feeling in his heart made him firm in his heart.

He will definitely learn the exercises in this, and this black stone wall will be used by him.

Looking at Wang Yan's resolute expression, Priest Cheng Yu already knew in his heart that after such a long time of understanding Wang Yan, it was impossible for him to do something that he was not sure of, since he was willing to spend money to auction these two items back, he must have some idea, or the ability to use them.

"Okay, I won't say more, we think you will answer the doubts in your hearts, and I will not leave you to sit for a long time if I continue to cultivate. Priest Cheng Yu said.

Wang Yan and the three of them saluted to the priest of Chengyu and then went out of the room.

Wang Yan took a deep breath, if he could use this black stone wall, then he would have a lot of help in the future, he had a lot of hole cards in his hand, but every time he faced the enemy, he still felt that it was not enough.

Every time he fights, he will have a deep sense of powerlessness, and it is urgent to improve his cultivation to increase his strength, and he himself began to look forward to tomorrow's Quenching Pool line, and when the time comes, he can improve his cultivation to that point, full of expectations.

After leaving the Chengyu priest's room, Chu Er took Xiao Mo'er back to their own room, after all, it was getting late, so naturally it was impossible to continue to stay together.

After Wang Yan returned to the room, he took out the mysterious book from the space bracelet.

The black stone wall is of no use to him now, and if he wants to use the black stone wall, the most important thing is the mysterious book.

After opening the mysterious book, what greeted his eyes was the pages and pages, the words that were deep and difficult to understand, although he had not been in this world for a long time, but the words and some cultural inheritances in this world were actually the same as those of the Fire Cloud Country before them.

Therefore, it makes sense to be able to understand the words of this world.

But even though the Dasheng Dynasty and the previous Huoyun Kingdom didn't seem to have any record of the text in this book, it made Wang Yan a headache.

I can't see how to cultivate, which is a big problem.

Wang Yan closed his eyes gently, if his eyes can't see it, then he can experience it with his heart, and it is definitely not an ordinary thing to be able to feel it in his heart.

Wang Yan covered his consciousness with his mind on the mysterious books, and those strange words swam out of the pages like swimming fish, presenting a beautiful picture scroll in front of Wang Yan.

After they were arranged, those words were like the sound of the Great Dao that had been affecting Wang Yan's mind, making his vision more and more blurred.

He saw the first word appear in front of his eyes, and the word was magnified dozens of times, and then Wang Yan realized that these were not real words but actions, and the words that appeared were the first form of this mysterious book.

Wang Yan pointed into a sword and learned the first type of action to make a comparison, and when he finished learning the first type of action, the second word immediately appeared in front of him.

Then Wang Yan followed suit.

The mystery book was very thin and only five pages, and each page contained about twenty words, which means that there were about a hundred actions in this secret book.

As time passed, about two hours later, Wang Yan had already practiced the movements in the entire book.

Wang Yan slowly opened his eyes, exhaled a breath of turbidity, and took a deep breath.

If you don't think about the words in this book, you won't be able to study them for a long time.

Wang Yan was also glad that after his divine sense touched the book, it would automatically surface the moves in front of him, otherwise he would not be able to complete it in a short time if he wanted to understand the inside of the book.

Looking at the night outside, the time was just at midnight, and Wang Yan didn't feel sleepy at this time, so Wang Yan simply closed his eyes again and practiced his sword moves over and over again.

The sky was full of fish white, and the movements in Wang Yan's mind were like watching a horse lantern, fused and coherent.

After a night of practice, Wang Yan has integrated all the movements.

Originally, when Wang Yan wanted to finish his cultivation, four big words appeared at the end of the action, "Evil Sword Technique." ”

Seeing these four big characters, Wang Yan's heart was deeply shocked.

The name of this mysterious book is actually the same as the name of the evil sword he wields.

Could it be that there is a providence in this darkness?

How could there be such a coincidence in the world, and he learned from the senior sister about the inheritance of sword moves in the North Sword Villa.

There are a total of seven swordsmanship books in Beijian Villa, and his seven senior sisters and brothers happen to have one each.

According to the door rules of Beijian Villa, only the owner of the village has the right to learn these seven swordsmanship, and Mu Sirong's identity has always been the acting owner, and she has no right to learn these seven swordsmanship completely.

However, among these seven swordsmanship, there is no name for the evil swordsmanship, could it be said that the North Sword Villa has lost many of these most important exercises in the past thousands of years.

The doubts in his heart could only wait until he returned to Beijian Villa and asked his senior sister and ancestor to wait for an answer.
