After Xiao Yu came to the library pavilion, he ignored the woman in black sitting at the door reading a book, but went directly to the second floor, and there were also many legal decisions on the bookshelves on the first floor, but these Xiao Yu were not very interested in these basic legal decisions.

When he was consulting the ancient books about alchemy law decisions, he roughly browsed the law decisions on the first floor, all of which were some basic spells suitable for disciples in the Qi cultivation period to cultivate, nothing more than fireball techniques, wood thorn techniques or something, how could he be interested in these.

The second floor was a collection of spells from the foundation building period, and he believed that he would definitely be able to find spells suitable for his cultivation on the second floor.

Before Xiao Yu came to the bookshelf, he excitedly flipped through a jade slip, but after looking at it for a while, Xiao Yu was a little interested.

This is a spell called the Flying Needle Technique, once cast, it can instantly shoot out hundreds of flying needles condensed by spiritual energy, which makes it difficult for people to defend and is also very powerful, but this is not the spell that Xiao Yu wants, he is not willing to confront others head-on, maybe he will hang up by accident.

Xiao Yu picked up another jade slip, this method is called the Shadowless Knife, and it is also a knife condensed with true qi, this knife can be hidden in the invisible, it is a sharp weapon of the Yin people, but it can only be used once, because no matter how much true qi the monk who uses this spell has, it will be emptied at one time, this move is a spell that becomes a benevolence if it is unsuccessful, and the opponent does not die after using it, then the death can only be himself, and Xiao Yu does not like this spell.

He had been on the second floor for a few days, and in the past few days, he had browsed almost all the spells on the second floor, but such a large library had collected more than 10,000 foundation-building period spells, and none of them were the spells he really wanted.

Xiao Yu is a little depressed now, do you have to go up to the third floor? The third floor is a spell that only the elders of the Jindan stage can use!

Although he has a lot of spirit stones now, he still has some self-knowledge, the spells of the Jindan period are not something that he can afford with such a little net worth now, and he can't cultivate the spells of the Jindan period!

After all, Xiuwei has not yet stepped into the foundation building period and is thinking about cultivating the spells of the Jindan period, which is a bit ambitious!

The spells of the foundation building period on the second floor were almost finished, only a few jade slips on the corner had not been checked, and Xiao Yu had no hope.

The law decisions placed in the corner, almost no one is willing to cultivate, but Xiao Yu has the attitude of preferring to kill mistakes and not letting go, and still sticks those jade slips on his forehead one by one to read the contents inside, this time Xiao Yu is not so disappointed, because he has not reported hope at all, so naturally he will not be disappointed.

But at this moment, Xiao Yu suddenly opened his eyes and stared at the jade slip in his hand in disbelief, he couldn't believe how such a jade slip could appear on the bookshelf on the second floor!

What is recorded in this jade slip is not a spell, but the score of an ancient song, this ancient song seems to have nothing special at first, and it seems that it has nothing to do with the law at all, but Xiao Yu demonstrated it in his mind according to the notes on the score.

But he inadvertently found that when he played the score, he was hidden deep in the depths of his soul, and the Yuan Shen in the sea of knowledge was a little trembling, he knew that his Yuan Shen was special, even if it was the impact of the divine thoughts of the Jindan monks, it might not be able to break through the defense of the Yuan Shen.

But such an ancient song, but let his Yuan Shen tremble, it seems that if he was not encountered here, I am afraid that no one would be able to find out the special features of this music score, Xiao Yu did not hesitate, and hurriedly came to the door of the first floor, and asked the woman in black who was reading a book about this jade slip.

When the woman in black took the jade slip, she probed and said: "This ancient song is called Requiem, it was made by a music theory master in ancient times, and it was inadvertently obtained by the predecessors of this pavilion, but no one has been able to play it in the Dragon and Phoenix Pavilion for so many years.

It is said that it is because no one can resonate with this ancient song, so I advise you not to choose this ancient song, so far no one has been able to fully comprehend this ancient song, and no one knows what it is really used for. ”

Xiao Yu just smiled when she heard what she said, and still asked: "Uncle Shi, the disciple wants the original of this music score, I don't know if it is feasible, after all, this music score is useless, only people like the disciple who like some strange things will need it, so the disciple wants to buy the original, please Uncle Shi to complete it"

The woman in black was a little embarrassed: "According to the regulations, the law of the Library Pavilion is not allowed to take away the original, but this score has always been unattended, as long as you make twice the contribution, you can leave a copy of the jade slip and take the original!"

In fact, Xiao Yu had long expected that she would say this, so she hurriedly took out 20,000 spirit stones and handed them to the woman in black, because in the Dragon and Phoenix Pavilion, the first and second layers of the law can be bought at double the price, but few people will do this.

The law decision in the original is the same as the law decision in the copy jade slip, few people will be so stupid, and it costs twice the price to buy the same thing, but Xiao Yu doesn't think so, he believes that there must be some secrets in the original that no one else has discovered.

This ancient song is already able to shake his own Yuan Shen just by copying the beginning part, and the complete score must have its extraordinary place, only he knows it, and this time he has picked up the treasure again.

Taking over a scroll of parchment with a simple atmosphere, Xiao Yu didn't dare to demonstrate the tune according to the score, but checked it and put it in the Qiankun bag and left the library.

After returning to the cave, Xiao Yu came to the practice room, Xiao Jiumei was not there, the little girl has been teaching Xiao Candy to practice for a while, although Xiao Candy is not a Tianling root, but her qualifications are also good, so Xiao Jiu Mei is even more attentive.

Xiao Yu didn't have the heart to care that the little girl was lazy again, took out the parchment scroll and came to her senses, Xiao Yu used his mind to evolve the tune of the score, and the feeling of Yuan Shen tremor appeared at one time, and it was even stronger than the last time.

Xiao Yu found that the original simplicity was really different, so he continued to evolve, the feeling of the Yuan Shen tremor became clearer and clearer, and he felt that the Yuan Shen in the sea of consciousness was a little stinging, and the feeling of pain in the soul was really not something that ordinary people could bear!

Just after Xiao Yu finished evolving a note of zuihou, the music score written in gold dust on the parchment scroll floated at this moment, and drilled into Xiao Yu's sea of consciousness along Xiao Yu's spiritual platform.

This kind of thing caught him by surprise, and before he could react, a pleasant light voice sounded in his spiritual sense, which was obviously a woman's voice: "Little guy, you are the first descendant who can endure the torment of the soul and complete the evolution of this requiem song in so many years, it seems that you are qualified to become the only inheritance left in the world by this palace."

This requiem was composed before the ascension of this palace, and it can't be obtained by people who are not mentally fortitimate, but now it can be inherited, and finally it is a matter of heart. ”

The woman sighed for a while, and then said: "This palace is the leader of the Tianyin Sect, and it has already ascended to the spirit realm, and I don't know how many years have passed since this palace!

This palace doesn't have anything to ask you, I just hope that in the future, you will succeed in your cultivation, and when you meet the juniors of this sect, you will have a lot of help or two, and you will have a fate to zaijian!"

Until this voice disappeared, Xiao Yu was still in a state of daze, Tianyin Sect Xiao Yu had never heard of it, and he had never heard of this Tianyin Fairy, but thinking of the predecessors who had ascended to the spirit world many years ago, Xiao Yu was excited.

Immortal cultivators who can ascend to the spirit realm, which one is not amazing, otherwise there would not be so many people stuck on the bottleneck of the god transformation period, zuihou sat down regretfully.

How could the inheritance left by that ascended predecessor be an ordinary commodity, thinking that if this magic trick is discovered, I am afraid that the broken head will also be grabbed, this time it is really worth the trip.

Xiao Yu hurriedly used his divine mind to check the law decision in his spiritual sense, and found that there were twelve ancient songs recorded on the law decision, and the first ten ancient songs were all law decisions that used sound waves as a means of attack, but the two ancient songs in the back were very extraordinary.

They also use sound waves to attack, but there is a divine mind attack technique hidden in the sound waves, this requiem is one of them, but this ancient song needs to reach the Yuan Shen realm to reach the golden pill stage before it can be cast, otherwise after casting, before the enemy's soul is injured, his soul will be shattered.

It just so happens that his Yuan Shen realm has reached the level of the Jindan period, it seems that he can practice this ancient song, not only will he not lag behind in the future, but he may be more powerful than the little girl at that time!

Xiao Yu didn't immediately practice this ancient song, and looked at another ancient song, this ancient song is called Broken Requiem, this name is really terrifying!

He read it carefully and found that this ancient song is different from the Requiem Song, the sonic attack of the Requiem is just a disguise, and the impact of divine thoughts is the key, but this ancient song is even more powerful, not only can it send out a divine impact that is no less than that of Requiem, but the sonic attack is also extremely sharp.

When performing this ancient song, two sharp arrows can be issued, one of which is transformed by spiritual power and fired through the strings, like a bow and arrow, and the other arrow made of divine thoughts will pierce the soul of the enemy when he dodges the sharp arrow.

For immortal cultivators, the wound of the soul is more serious than the wound of the body, and the physical injury can be repaired or reborn, but once the soul is killed, it is really the soul is scattered, so this trick is even more powerful.

But Xiao Yu had to give up cultivating this ancient song, because he couldn't cultivate it now, and the minimum requirement for cultivating this ancient song was to cultivate after reaching the Yuan Infant Stage, that is, the cultivation of the body and the realm of the Yuan Shen had reached the Yuan Infant Stage.

Xiao Yu is still far from meeting this requirement, so he doesn't think about this ancient song for the time being, it's good to practice the requiem song first, and he can't be in Longwangshu!
