Sorry, I'm a villain

What else could Lin Yu say, he could only shake his head, "Junior sister is smart and admirable."

As for a disciple from a poor family, 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 lightly touched his messenger jade and Yu Xianwan's messenger jade, and the mailing address was memorized.

The girl took back the message jade with a smile and said, "Welcome to visit again!"

Lin Yu nodded, turned around and left.

After entering the door with his identity token, he saw an elevator, or a spiritual ladder!

The overall structure is exactly the same as that of an elevator, except that the elevator's motor is replaced by a magic circle inlaid with spiritual stones.

After he stood up, the elevator started.

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

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

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

The old man was wearing a whitish navy blue robe, sitting on a recliner, drinking tea and reading a book.

"No wonder there are only two guards at the fourth level of Qi Refining in the Library Pavilion. It turns out 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 monk at the ninth level of Qi Refining!

Lin Yu walked up to the old man and asked politely, "Excuse me, senior brother. Excuse me, senior brother, I want to apply for a skill, what should I do?"

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

"Tsk, tsk, you are still practicing basic techniques at the sixth level of Qi Refining. Your boy has a bright future!"

Although the exercises for the initial stage of Qi refining have different names, they are collectively called basic techniques.

Who would be willing to practice basic techniques when they can change the techniques!

Lin Yu smiled bitterly, "Senior brother, stop teasing me!"

"You haven't learned the exercises at the sixth level of Qi Refining, so you must have had an adventure. For such a person, it's not too much to say that he has a bright future, right?" The old man's eyes seemed to be able to see into Lin Yu's heart.

Lin Yu's expression changed slightly.

Seeing his expression, the old man felt bored. He simply lay back on the chair and read a book, "The exercises are on the third floor. There are stairs over there. Once you have selected the exercises, take them down and I will register them for you."

"The little girl downstairs has told you the specific requirements, so I won't go into details."

The old man waved his hands as if to shoo away flies.

Lin Yu was a little helpless, but he was also 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 something.

"What a coward."

There is more than one person who has an adventure!

Lin Yu didn't know that someone was laughing at him. He was now standing on the third floor, looking at the bookshelves inside with bright eyes.

"Too much! Too much!"

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

Although the books here are not comparable to those on the first floor, there are still hundreds or even thousands of books!

These are exercises, not those miscellaneous books!

The value of a skill depends on the upper limit of skill cultivation. The upper limit is between 300 and 1,000 spirit stones during the Qi refining period. But if the upper limit is the immortal level, then the value of the skill will skyrocket!

The upper limit is only the primary level of Heavenly Immortal, and such a skill is worth 2,000 to 3,000 spirit stones!

Further up, the value of the exercises is even more astonishing.

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

There are hundreds of exercises on the third floor of the library. Even if they are all Qi-refining exercises, they are worth tens or even millions of spiritual stones!

Although Lin Yu has a small amount of assets now, compared with the skills on this floor, they are just a drop in the bucket!

After flipping through a few books on the exercises, he had an idea.

"Although Yu Xianwan is cheating, the things she gives are genuine!"

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 for a while and decisively walked towards the fire attribute skill area.

Although you can't tell it, he is actually a fire attribute monk.

In the fire attribute area, he flipped through several exercise books, trying to find one that suited him.

The exercises here are all trial versions, only the content of the 4th level of Qi Refining. If you want all the content, you have to go to the old man on the second floor to redeem it.

However, the trial reading section also allows people to test their aptitude.

Practice according to the exercises. If you feel good, then it is a suitable exercise. If not, you should choose another one.

Although Lin Yu is at the 6th level of Qi refining, he still needs to start from the 4th level of Qi refining when modifying his exercises. Therefore, these exercises are enough for him to experiment with.

Of course, Yu Xianwan had already recommended the Five Classics to him. But Lin Yu just refused to accept it. He wanted to find a technique that was more suitable for him.

But soon after, he gave in.

“It smells so good”!

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

The Five Classics is not the name of the exercises, but the general name of the five powerful exercises.

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

But the Five Emperors came to the world, created the practice method, and led the human race to rise from then on.

The practice methods created by the Five Emperors are the "Golden Jade Sutra", "Lingmu Jue", "Shui Jing Zhu", "Burning Industry Book", and "Zhenshan Scroll", collectively known as the Five Classics.

The Five Codes are classics passed down from generation to generation by the human race, and each major sect has its own corresponding inheritance of the Qi Refining Chapter and the Heavenly Immortal Chapter.

Xu Chuyi practiced one of the Five Classics, "Shui Jing Zhu".

Of course, Lin Yu and the others only received 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 do you want?"

"The Book of Burning Industry."

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

Lin Yu handed over the token.

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

"The "Book of Burning Industry" is inside and can only be read once." The old man looked at Lin Yu with a serious face, "Remember! It is not allowed to be spread to outsiders. Otherwise, at least it will be sent to the vanguard army, and at worst, it will be executed on the spot!"

Although it is only a partial chapter, the importance of the Five Codes is still undoubted. Any sect with the inheritance of the Five Codes will do everything possible to protect the inheritance of the Five Codes from being leaked!

Lin Yu nodded, turned and left.

He wants to go back to practice.

The spiritual power in his body was derived from practicing basic techniques. It must first be converted into the spiritual power of "The Book of Burning Industry" before he can continue the practice after "The Book of Burning Industry".

The spiritual power converted through the "Book of Burning Industry" is violent and powerful, but consumes more energy. Generally speaking, it is good at short-term bursts.

Moreover, "The Book of Burning Industry" does not have accompanying spells, and practitioners need to go to the spell area on the second floor of the Book Collection Pavilion to redeem it. Of course, it can also be obtained 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 practiced in seclusion.

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

The skills developed through the basic techniques are gentle and impartial, and are suitable for conversion into any kind of spiritual power.

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

"Now I am a master at the sixth level of Qi refining!"

He stood up and opened the door with confidence.

A messenger talisman came right in his face.
