Looking around, Zuo Ci has already found that the books in the library are indeed classified according to certain rules. For example, the outermost circle of this circular room is basically placed with various related magic, secret books, black and white magic, and different elements.

The twenty bookshelfs scattered like fan bones are placed in categories with three different geography, history, biology, and religious books of different major categories. In addition to these twelve classified bookshelfs, the other eight bookshelfs are placed with alchemy, engineering knowledge, weapon expertise, cooking related, enchantment topics, archaeological documents, and two major government notes waiting for Zuo Ci to quietly walk around the outer bookshelf, and then he already knows the location of each category.

After understanding the classification, the area to be looked for was reduced a lot. Zuo Ci quickly circled the bookshelf at nine o'clock. All the bookshelf placed on it were historical contributions related to Manchester 6. However, the entire bookshelf was arranged in thousands of books, and both sides were placed. He started to observe from the lowest row of the bookshelf facing the north side, swept up one by one, and planned to view this side if it was not visible after reading it, and continue to observe from the bottom of the other side-

When scanning the bookshelf, Zuo Ci tried to be as fast as possible but kept it carefully. He often saw one or two books of interest in the middle, but the task was important, so he focused more on finding books.

After spending an hour checking a bookshelves and finding nothing, Zuo Ci changed to another one and spent another hour. But strangely... he still did not find the book "The Collection of Melting Fire".

[Strange.] Zuo Ci frowned, [Isn't this a history book that records the Battle of Molten Fire? Why can't it be found in the Manchester History Classification Bookshelf?]

Fearing that he might have missed it, Zuo Ci spent nearly two hours checking it again, but still couldn't find the book.

[Isn't it in the history classification?] Zuo Ci leaned against the corner of the bookshelf, clutching her hands, frowned and wondering whether she needed to check each bookshelves one by one, or... [Is this book really there in this library?]-

After finally getting into the library, even if you have any doubts, you have to eliminate all possibilities as much as possible. Zuo Ci decided to check each bookshelves one by one, starting with the outermost circle of books full of magic books.

The booklets in the category of magic are the most numerous in the entire library, with tens of thousands of volumes. Zuo Ci is more focused than before and speeds up the inspection. He spent more than two hours passing through the magic book group, but unfortunately, he still got nothing.

After watching this circle, Zuo Ci began to feel a little tired. Nearly five hours have passed since yesterday dusk. At this time, it was almost morning and he was not sleeping. It was also worth it to have this feeling. Fortunately, before leaving the hotel this morning, he had enough dry food, so he took out a few pieces of bread and leaned against the shadow to eat-

The simple breakfast time ended in more than ten minutes. Zuo Ci cheered up and continued to explore the work. He decided to rule out eight bookshelfs related to Keen University 6 and Leh University 6, as well as the Manchester history classification that had just been inspected, and check the remaining eleven bookshelfs one by one.

Of course, he also made a priority classification, planning to check biological classification according to geography, religion, archaeological documents, government records, alchemy, enchantment topics, engineering knowledge, weapon specialization, cooking-related, and finally check biological classification.

He was mentally prepared. If he still couldn't find the "Molten Fire Collection" after checking these bookshelfs, he could only check the other two major 6 materials.

Just as the construction was about to start, three knocks came out of the gate of the library. The waiter floating in the air came back to life again, drifting down near the ground, and waved his hand and the iron door opened.

When the door opened, Zuo Ci entered a state of shadow escape and merged into the shadow of the bookshelf-

A strange voice sounded outside, and he asked the waiter: "Click out the notes from the Imperial Council last week to me."

Without looking outside, Zuo Ci also knew that the waiter must have waved his hand once, and the book book requested by the strange man flew in front of them. After a while, the outside became calm again-

Continuing to start work, Zuo Ci cheered up and checked the bookshelf one by one according to his plan. The degree of speed has indeed accelerated. He can start to check the content of a book on both sides within an hour.

There is no geographical classification, no religious classification, no archaeological classification, no government record classification... There is no alchemy, enchantment topic, and engineering knowledge... Eight hours passed, and Zuo Ci felt a headache, but he still found nothing.

Zuo Ci rubbed his eyebrows and could only continue, and began to check the classified bookshelf of the relevant weapons. However, just as he spent a quarter of an hour looking up from the bottom, he finally saw a red-brown shell with a slightly worn corner, without any edges and looking inconspicuous book. The cover read "The Collection of Melting" in a few small words. (To be continued.)
