Following behind the old man, at a distance of about twenty or thirty meters, Ye Chen and the two came to an attic door, and when they looked at the attic door number with the words "library building" written on it, they knew that they had arrived at their destination.

As a place for the collection of martial arts, the defense here is also extremely strict, and there are several martial artists of the acquired realm in the bright place alone, not to mention the one in the dark!

However, since Baibaolou is a merchant, of course these martial arts will not be good-looking, standing at the door, Ye Chen saw that there were several figures in the library to choose from!

After greeting the old man, he stepped into the library building, a heavy smell of books came to his face, Ye Chen's eyes swept away, the space was really not small, large and small bookshelves were displayed in the building, and many martial arts were also placed on the shelves!

With so many martial arts, Ye Chen was also taken aback when he entered the Ye family's martial arts pavilion, the number and variety of this collection are much richer than the Ye family, which shows the power and heritage of Baibaolou!

Baibaolou has also classified martial arts, making it easier for guests to find and choose, distinguishing the types of martial arts from the color of the bookshelf, the red bookshelf is the offensive martial arts, the yellow is the defensive class, and the cyan is the body method.

Each bookshelf is also marked with logos, such as fist techniques, swordsmanship and the like, it is not difficult for Ye Chen to find the knife technique, so he walked straight towards the red bookshelf marked with the knife technique!

First-order martial arts, mountain opening knife technique

First-order martial arts, Wind Strike

Second-order martial arts, breaking the wind and slashing in the air

All kinds of sword techniques came into Ye Chen's eyes, but almost all of the martial arts he saw were first-order martial arts, very few second-order martial arts, and none of the third-order ones were found.

Ye Chen didn't care, after all, even if the third-order sword technique was placed in front of him, he wouldn't be able to afford it!

Shaking his head, Ye Chen picked up a book of first-order sword techniques and looked through them carefully, but after he looked through several books in a row, he was surprised to find that the martial arts here only had one name and a simple introduction, and there was no complete cultivation method recorded!

Then Ye Chen also smiled and was relieved, if the martial arts were completely placed here, it would be impossible for those library buildings to come and go at will, otherwise it would be over if they came directly to steal the school, who would spend money to buy it!

However, it is still a little difficult to find a suitable martial art just based on the exaggerated introduction and name, so the other people present are also hesitant in the face of martial arts.

Seeing this, a hint of a smile appeared on Ye Chen's face, he didn't think that he would face a hesitant choice, silently clicked on the system to check, but got an answer that made him smile bitterly, "Trash!"

"......" The smile froze on his face, Ye Chen was not discouraged, picked up another book and continued to investigate, and finally picked up a second-order martial art, and got the same answer, Ye Chen's heart was full of helplessness, the vision of this system is too high!

Turning over the back of the martial arts, it made Ye Chen want to cry without tears, these martial arts that were rated as garbage, the cheapest one cost 10,000 gold coins, even if he sold the remaining Meditation Pill, he couldn't afford it!

"Don't talk about garbage, I can't afford to buy garbage now" Ye Chen smiled self-deprecatingly, put down his martial arts and prepared to leave, his eyes suddenly swept to the corner of the bookshelf, where was there actually a martial arts without a cover introduction, and when he looked at it, it was just a few pieces of old and yellowed paper.

"What is this?"

Ye Chen stepped forward and held it in his hand with a puzzled gaze!

I looked at the worn-out yellow paper in my hand in a daze, because of the age, the handwriting was a little blurry, according to some keywords, it could be vaguely seen that it was a knife technique!

Since you can't understand it, you can use an intuitive method, and Ye Chen clicks on the system to check it!

"Ding, the host level is too low to find out the name and level of the martial arts!"

Ye Chen was slightly stunned, could it be that he had really picked up the treasure? Before he could be happy, another hint followed!

"You can complete the first type of the first sword, do you spend a thousand exchange points to complete it?"

Hearing the prompt sound of the system, Ye Chen almost jumped up happily, his face was full of excitement and excitement!

If this kind of incomplete martial art can be repaired by the system, although it costs a bit much, but the martial art that can be recognized by the system will not be too bad.

After being excited for a long time, Ye Chen gradually calmed down, after all, this martial arts fragment did not belong to him.

Suppressing his excitement, Ye Chen walked towards the back of the transaction, and the guards of the library building didn't need to stop him, after all, the real martial arts can only be obtained after paying for them, and the martial arts here are just a catalog introduction for people to choose!

Although the martial arts are expensive, Ye Chen has a trace of luck in his heart, "The true level of this martial art must not have been discovered, otherwise it would not be openly placed in the library building, plus it is incomplete, it shouldn't be too expensive!"

All the way unimpeded, Ye Chen returned to the back of the trade fair again, and as soon as he stepped in, an enthusiastic voice came into his ears!

"Your Excellency, have you chosen your martial arts?" Although the old man was puzzled by Ye Chen's selection speed, he thought of the shopkeeper's explanation and greeted him with a warm face.

"Hmm!What is the price of this martial art?" Ye Chen was apprehensive in his heart, but on the surface, he still handed the fragment to the old man very casually!

The old man took the paper, his brows furrowed slightly, as the old man of Baibaolou, he naturally knew this fragment.

It is said that a team of mercenaries brought it out of the monuments, and if the study was not thorough, it was sold to Baibaolou, and Baibaolou also sent people to study it, but the defect was too serious, and it was not possible to study a useful move and a half, and I could only vaguely feel that the level of this martial art was not low!

But just give up, Baibaolou is also unwilling, so intentionally or unintentionally put it in the library building, hoping that someone can detect useful information, but after so many years, there are many interested people, but they have not been able to get any useful information, and it has been gone for a long time!

If it weren't for seeing these fragments again, the old man would have almost forgotten that there was such a martial art, looking at Ye Chen, who was covered tightly by a black robe, the old man raised his eyebrows, "Could it be that this person found something?"

"Your Excellency, this martial art is so crippled that many people have failed to succeed after trying it, and they have finally been abandoned!" the old man smiled slightly, and said tentatively.

Of course, Ye Chen wouldn't let him see the clues, and nodded politely, "Hehe, I'm just more interested, if I can find something, it's a good thing, if not, it's a collection to commemorate!"

"Eh!" Seeing Ye Chen's answer like this, the old man also choked for a while, and some words that he had prepared were also blocked in his mouth, and he shook his head with a wry smile!

"The price is five thousand gold coins," the old man said helplessly.

Without waiting for Ye Chen's reaction, the old man reminded again, "If you haven't realized anything after a long time, you can return it, and we will also compensate you, of course, if you comprehend valuable moves, we are also willing to pay a lot of money to buy it!"

The latter sentence is the old man's business, and those who bought the fragments in the past will be reminded that after a period of time, the buyer will lose interest in selling the fragments and continue to stay in the library waiting for the destined person!

"Whew!" Ye Chen breathed a sigh of relief when he heard the price, there was still a Meditation Pill in his arms, plus the gold coins obtained from the sale just now should be enough, as for the second half of the old man's sentence, Ye Chen automatically ignored it.

How is it possible!
