Half a month later.

"I'm skilled in fighting and stealth."

Calando soothed his body, which was constricted from cultivation and stealth hiding.

Combat stride is a footwork technique specially used in fighting, and it can also be used in ordinary life, whether it is walking, sitting or lying down, it can burst out and hurt people in an instant.

Stealth is an assassin technique of walking and hiding in the shadows. It contains how to walk silently; how to use obstacles to hide; how to reduce the body (similar to bone shrinking) to hide in places that could not be hidden; how to weaken one's own presence; How to avoid the sight of others and enter the blind spot.

"The caravan has been contacted, and it will leave for Issi in the early hours of the day after tomorrow. Without further ado, I'll explore the top floor of the library at night tonight. ”

……

Late at night.

Calando skillfully hid in the shadows next to the door of the Tree of All-Knowing Library, quietly watching the library's night watchman patrol the fifth floor before returning to the break room on the first floor.

"Why don't the night watchmen patrol the sixth floor?"

With this question in mind, Carlando used the technique of stealth and hiding, avoiding the perception of the night watch, and sneaked into the first floor of the library.

Lao Ma found the door from the third floor to the fourth floor, and after some fumbling, he was stunned to find that the door was not locked. Is it for the convenience of patrolling on the way? It's not good to be too peaceful, it's especially convenient for people like me. Applying no more or no less vegetable oil (as lubricating oil) to the door shaft, he quietly opened up enough space for him to pass through.

"I see......"

After a little probing on the fourth floor, Carlando understood why the fourth floor was the middle floor. The Library of the Tree of Omniscience looks like a swimming ring on the Tree of Knowledge, and the first, second, and third floors of the building are at a certain distance from the trunk of the tree. The fourth floor is further afield, and there is no need to take stairs to reach it, it is the same floor as the third floor, but further away from the trunk of the tree. The only way to reach the fourth floor is the previous gate and the violent breaking of the outer wall on the third floor......

Since there was no distribution map of the books above the fourth floor, he could only pick up the glimmer stone and look for it himself.

"Nothing?"

After searching for nearly two hours, Carlando did not find a single useful thing, either a real miscellaneous book or a book for scholars.

"No, it's the same on the fifth floor, right?"

The fifth floor is above the fourth floor, and there is more than one staircase to go up.

Although Carlando thought it was very possible, it was a pity not to look for it.

"Forget it, take a quick look, it's up to you to see if you can find anything good."

The top floor of the library is the top floor.

Forty minutes later.

"! How do I get to the top floor of this library? ”

After a cursory search of the fifth floor of the library, Carlando found that he could not find a place to reach the top floor.

"Is there a mechanism? The fifth floor is not small, where will the mechanism be? This is a ......."

……

Because of the time, he couldn't probe carefully without a wall, but he found an important place.

The office of the librarian, Kuroha.

"By the way, I haven't seen the famous Dr. Clover yet? In fan fiction, it is written that his hair and beard are in the shape of a clover, so peculiar? Really? ”

stepped forward and turned the handle, found that the lock was locked, took out the lock picking tool, and began to pound it. After seven or eight minutes, he gave up using technology to open it.

Two all-out wind blades cut a V-shaped gap next to the handle, and with a gentle push, they dodged in.

Getting the door back to its original form, he turned on his flashlight for a quick glance before shutting it off. Then, based on the experience of movies and TV series in his previous life, he began to experiment with the furnishings on the desk, the various decorations next to the table, and the books on the shelves......

"Click! Click! ”

"Is it a book? It's really dedicated. ”

I watched the bookshelves in front of me parting left and right, revealing a door on the wall, which also parted left and right. When everything was quiet, Carlando stepped inside.

In front of me is a long staircase, which is connected diagonally to the main trunk of the tree...... Inner floor, 6th floor.

"That is, unless you can fly, this is the only way to go? Isn't it just cherishing literature? As for such a vigorous repair mechanism? ”

Not knowing what the archaeologist was thinking, Carlando made his way up the stairs to the door of the sixth floor. He looked down at the lock, which was clearly made of special metal, and smiled disdainfully.

"Although my wind blade can't even cut through steel now, I can cut open the wooden door."

I don't know what the people who built this door thought, special metal locks with hardwood doors? Repeating the previous operation, Carlando pushed the door and entered the sixth floor.

I pulled out my flashlight again and glanced around.

"There are no windows, only fan vents, and it's hard for the light from the inside to get out."

Carlando, who came to this conclusion, simply kept turning on the flashlight and looked for it.

Excluding those that are obviously historical documents and the titles of the books are incomprehensible (special words), he simply flipped through them one by one.

"Found a treasure ......"

Carlando has always wondered what O'Hara makes money on? Only a small part of the books are donated by scholars from all over the world, and the rest of the books are basically bought from all over the world, plus the shipping costs, which is not a small amount......

Until he saw the book in front of him, looked at the detailed recipes and detailed process production processes, including the sleeping liquid he had used.

"O'Hara, is this making money from patents? I said that the archaeologists in O'Hara either read books or studied history all day long, and there are no mines on the island, so how can they still be so rich, it turns out that they rely on royalties! ”

Of course, they may not be called royalties, but that's what they mean.

"Just take it whole?"

Carlando pondered for a moment and decided no. He will definitely take the Devil Fruit Illustrated Book, and as soon as this matter is exposed, Nicole Robin will definitely be able to guess that I did it, and she should not report me on this Devil Fruit Illustrated Book. But if this thing is lost, she will definitely not keep it a secret for me under the library's full investigation.

In the time period when CP is about to log in, he only wants to be obscure. There was no way, Carlando took out a pen and paper, picked some that seemed to be available on the market, and copied them with high benefits.

Putting the book back in its original flavor, he continued to look for something useful.

"Illustrated Objects and Materials?"

Carlando looked at the strange name, stretched out his hand and looked at it a few times, isn't this a famous knife book? It turned out to be called this name.,Fan fiction hurts me a lot! Then he copied the important content non-stop.

"Evil, fruit, picture ......"

After copying and continuing his search, Carlando soon saw a book with a lock. Looking at the words on the dark cover that were blocked by the lock, Carlando directly made up the correct name. With little time left, he put the book straight into his bag.

Then I went through the rest of the title and found nothing of interest. So he went back the way he came, and sorted out the traces. Although the door cannot be repaired, it can be delayed for a while.
