The third floor, like the first floor, is filled with bookshelves, most of which are full of books, but there are far fewer books than on the first floor.

Zhou Su randomly took out two of them, and the quality of these books was much higher than that on the first floor.

The books on the first floor are basically white quality books, and there are many miscellaneous books of various lifestyles that belong to the ranks.

However, in this third layer, every book that Zhou Su randomly pulled out was all green quality books, and the books kept in this third layer alone were already more than the books in most small sects, even in the library of some medium-sized sects, there were not necessarily so many green quality books in the library pavilions of some medium-sized sects.

As he did on the first floor, Zhou Su sat down cross-legged and wrote down all these books with his divine sense.

This time, because the quality of these books has improved a lot, Zhou Su took a lot more time than he used on the first layer, but it was only less than two hours, and all the books in this layer were all remembered by Zhou Su.

After doing this, Zhou Su didn't stop and walked straight towards the fourth floor.

The fourth layer is the same as the second layer, and there are also a large number of basic materials for arrays, alchemy, and refiners, which belong to green quality.

Zhou Su just glanced at it, didn't stop, and walked directly towards the 5th floor.

There are also books on the 5th floor, but there are many fewer books than on the 3rd floor, and the quality here is a big grade higher than that on the 3rd floor, which belongs to the blue quality.

Zhou Su did not hesitate, immediately sat down cross-legged, and once again used his divine sense to memorize the contents of these books in his mind.

Since the quality of the books here has reached the blue quality, Zhou Su's time to write down these books is much slower.

Zhou Su climbed the tower layer by layer here, recording the various skills, exercises, and other kinds of knowledge collected in this tower, which was extremely leisurely, while those others who were hundreds of miles away from Zhou Su were still fighting with those crazy monsters, and little by little they were fighting towards the center.

After about four hours, Zhou Su opened his eyes, and a trace of joy appeared in his eyes.

Zhou Su stood up, the joy in his eyes was fleeting, and he didn't stay too long, and climbed to the 6th floor.

In the 6th layer, there are some weapon racks, and there are many magic tools that are at least blue quality or above, but these magic tools are only a few, and the most of them are various blue quality materials, these materials are the most valuable things in this layer, as for those magic tools, the quality can only be said to be better than the regular magic tools.

However, there are also some excellent ones, but they are only for most of the magic equipment with blue quality, and if they are sold, they are estimated to be able to sell for a good price.

The sixth floor is about the size of a basketball court, and most of the blue materials are filled here, except for the dozens of blue magic tools that are placed on the edges.

Zhou Su's Nine Phoenix Ring has also opened up the inner space to the size of a football field at this time, and it is enough to hold these materials.

Zhou Su was not hypocritical, and included all these things in the storage ring, and these things are still useful to the current Zhou Su.

After quickly sweeping all the things in this layer, and making sure that all of them were put into the storage ring and not missing, Zhou Su ascended to the seventh layer.

The seventh floor is much smaller than the sixth floor, and there are not as many things as the lower floors, this floor only has a bookshelf in the middle, and it seems to be empty, only three jade slips are placed.

Zhou Su stepped out, and his figure suddenly disappeared from the spot, and when he appeared, he had already come to the bookshelf.

Because this bookshelf is arranged here with a formation related to cleaning, it does not produce dust due to uninhabited all year round, but is spotless and clean.

Zhou Su first picked up the jade slip placed on the far left, and his divine sense directly probed into it.

Fire Cloud Step: Purple 3 pattern skill, there is a flow of fire between the actions of this footwork, and it is like a fire cloud rushing between cultivation and Dacheng action.

Zhou Su quickly wrote down all the cultivation paths and so on recorded in it, and then threw it into the storage ring casually.

Zhou Su picked up the remaining two jade slips, and his divine sense probed into them without the slightest stagnation, wrote down all the things recorded in them, and then threw them into the storage ring.

The probabilities within these two jade slips are: Yinyue slashes purple 5-pattern skills, refining Dacheng can make the heavens and the earth change color, and the sun and moon have no light;

The remaining two jade slips, the skills recorded in them are not bad, which is a priceless treasure for most of the people in the Holy Demon Continent, because most of the exercises they practice are white or green, and most of the disciples in those sects are only blue-level exercises, and only those who have a true 9th-order demon saint can practice purple exercises.

Whether it is a purple technique or a purple skill, this is extremely rare in the entire Holy Demon Continent, and every time a new purple technique or skill appears, it will set off a bloody storm.

The Silver Moon Slash can be handed over to Cloud Butterfly, which can increase her combat power a lot.

Zhou Su thought so, looked around this room, and found no other things, and his divine sense did not find any hidden grids or anything in this room, after making sure that there were no other things in this room, Zhou Su did not stay long, and went directly to the 8th floor.

The eighth floor was much smaller than the seventh, and this time there was less stuff than below, except for a small table in the very center of the room, on which was placed something like a gossip plate.

Zhou Su stepped out to the small table and picked up the gossip plate.

The Yin Yang Bagua Plate Purple 5-Pattern Demon Tool has most of the formations drawn in it, which can directly release any green quality formation, which can be used as the formation eye of the blue or purple formation, and the effect of the formation will be increased by 50% compared to the formation of ordinary items.

"This is a good arrangement of formation auxiliary magic tools. ”。

Zhou Su looked at the array plate in his hand and muttered softly, quite satisfied.

Zhou Su is mainly interested in increasing the effect of the blue or purple formation by 50%, and if this formation is brought back and the formation eye of the formation he arranged before is replaced, the effect of the formation will be improved a lot, and the progress of cultivation in it will be faster.
