What else could Lin Yu say? He could only shake his head, "The junior sister is smart and admirable."

As for the poor disciples, he doesn't believe it! Even if this girl is not a disciple of a noble family, she is definitely not an ordinary person!

He used his transmission jade and Yu Xianwan's transmission jade to gently touch it, and then recorded the transmission address.

The girl smiled and took back the sentencing jade and said, "Welcome to you again!"

Lin Yu nodded and turned around and left.

When he entered the door with his identity token, he saw an elevator, or spiritual power ladder!

The overall structure is exactly the same as that of the elevator, which means that the elevator motor is replaced with a magic array inlaid with spirit stones.

After he stood up, the elevator started.

The elevator slowly rose, and the door was automatically opened when it reached the second floor, and then the elevator stopped moving.

Lin Yu took a look and found that there was also a counter on the second floor, and there was a person sitting behind the counter.

However, unlike the young beauties on the first floor, there is an old man with white hair sitting behind the counter on the second floor.

The old man was wearing a white sea blue robe, sitting on a lounge chair, drinking tea while reading.

"No wonder the library only has two guards on the fourth level of Qi Refining. It turns out that there is a top-level monk sitting inside!" Lin Yu understood immediately.

This old man is a master! Moreover, he is probably a top-level cultivator at the 9th level of Qi Refining!

Lin Yu walked up to the old man and asked politely, "Announcing Senior Brother. Senior Brother, I want to apply for martial arts, what should I do?"

The old man turned his head and cast a strange look.

"Tsk tsk, the 6th level of Qi Refining is still practicing the basic magic formula. You kid have a bright future!"

Although the skills of the initial Qi Refining practice have different names, they are collectively called basic techniques.

Who is willing to practice the basic magic formula if you can change your skills?

Lin Yu smiled bitterly, "Senior brother, don't make fun of me!"

"I haven't learned the martial arts at the 6th level of Qi Refining, so there must be an adventure. It's not an exaggeration to say such a person, right?" The old man's eyes seemed to be able to see Lin Yu's heart.

Lin Yu's face changed slightly.

When the old man saw his face, he felt bored. He simply lay back on the chair and read the book, "The martial arts are on the third floor, and there are stairs there. Choose the martial arts and take them down, and I will register for you."

"I have told you the specific requirements, the little girl downstairs has told you, so I won't say much."

The old man waved his hand as if he was chasing a fly.

Lin Yu was a little helpless, but he felt relieved.

"Thank you, senior brother!" He thanked him and went up to the third floor.

Looking at his back, the old man snorted and muttered.

"I'm so brave."

There are more than one person who has adventures!

Lin Yu didn't know anyone was mocking him. He was standing on the third floor now, looking at the bookshelf inside with his eyes shining.

"Too many! Too many!"

Lin Yu walked around the bookshelf, his face full of shock.

Although the books here cannot be compared with the first floor, there are hundreds or even thousands of books!

This is a martial art, not those miscellaneous books!

The value of the exercises depends on the upper limit of the exercises. The upper limit is that the exercises in the Qi Refining Period are between 300 and 1,000 spirit stones. But if the upper limit is the celestial immortal level, the value of the exercises will skyrocket!

The upper limit is only the initial level of the celestial immortal, and such a technique is worth 2,000 to 3,000 spirit stones!

Going further up, the value of the exercises is even more amazing.

Most of the time, a skill is comparable to the entire wealth of a strong man of the same level!

The hundreds of martial arts on the third floor of this library, even if they are all Qi Refining Physicians, are worth dozens or even millions of spirit stones!

Although Lin Yu has some assets now, compared with the skills on this floor, it is a drop in the bucket!

After reading a few books of martial arts, he knew it in his mind.

"Although Yu Xianwan cheated on her father, the things she gave were real!"

Sure enough, the exercises on the third floor are divided into five areas according to the five elements. Each area divides the exercises into several different levels according to the level.

Lin Yu thought about it and decisively walked towards the fire attribute exercise area.

Although he couldn't see it, he was actually a fire-attribute monk.

In the Fire Attribute area, he searched for several martial arts, trying to find a martial art that suits him.

The exercises here are all trial versions, with only the contents of Qi Refining Level 4. If you want all the contents, you have to go to the old man on the second floor to redeem them.

However, the trial reading can also make people test their own characteristics.

Practice according to the exercises, if you feel good, it is the right exercises. On the contrary, you have to choose another one.

Although Lin Yu is at the 6th level of Qi refining, the modification of the exercises still starts from the 4th level of Qi refining. Therefore, it is enough for him to experiment with these exercises.

Of course, Yu Xianwan has already recommended the Five Classics to him. But Lin Yu just didn't agree. He wanted to find a more suitable technique for him.

But soon after, he still obeyed.

"It's so fragrant"!

The hundreds of exercises here can actually be divided into two categories - the Five Classics and other exercises.

The Five Classics are not the name of the martial arts, but the general name of the five powerful martial arts.

According to legend, the human race was originally just a weak race in the Great Wilderness world, and was often captured by various races as food.

But the Five Emperors came to the world and created the method of cultivation, leading the rise of the human race from then on.

The practice methods created by the Five Emperors are "Golden and Jade Sutra", "Lingmu Jue", "Water Sutra Note", "Bai Ye Shu", and "Zhenshan Volume", which are collectively called the Five Classics.

The Five Classics are the classics passed down from generation to generation by the human race, and each major sect has corresponding Qi Refining and Tianxian inheritance.

Xu Chuyi practiced one of the five classics, "Water Sutra Notes".

Of course, Lin Yu and the others only receive the Qi Refining Chapter for free.

On the second floor of the library, the old man behind the counter raised his head again and looked at Lin Yu, "Which book is needed?"

"The Book of Burning the Ones."

"As expected." The old man stretched out his hand, "Identity Token."

Lin Yu handed out the token.

The old man clicked on the token and then registered the jade book in the library, and then handed Lin Yu a jade slip of finger length.

"The Book of Fenye is inside, and you can only read it once." The old man looked at Lin Yu with a serious face, "Remember! No external rumor, otherwise, the vanguard army will be sent to the extreme, and the worst will be executed on the spot!"

Although it is only part of the chapter, the importance of the Five Classics is still unquestionable. Any sect with the Five Classics inheritance will do everything to protect the Five Classics inheritance from being leaked!

Lin Yu nodded and turned around and left.

He wants to go back to practice.

The spiritual power in his body is still derived from the basic magic formula. He must first be converted into the spiritual power of "Fengye Shu" so that he can continue the practice after "Fengye Shu".

The spiritual power converted through "Finye Shu" is violent and powerful, but it consumes more. Generally speaking, it is good at short-term explosions.

Moreover, "Baiye Shu" does not have any magic attached, and practitioners need to go to the magic area on the second floor of the Library Pavilion to exchange. Of course, you can also obtain it through other channels, such as gifts, purchases, etc.

However, the price of spells is not low.

Lin Yu returned to the dormitory, closed the door, opened the attached low-level magic circle, and went into seclusion to practice.

Converting skills is a difficult problem, but the basic skills are an exception.

The skills practiced by basic magic formulas are gentle and unbiased, and are suitable for conversion into any kind of spiritual power.

Lin Yu is at the 6th level of Qi refining, which takes longer than the 4th level of Qi refining, but after a whole day, he also completed all the conversions.

"Now I am a master at the 6th level of Qi Refining!"

He stood up and pushed open the door with confidence.

A message talisman came towards his face.
Chapter completed!
