"Whew!" With a slight sound of breaking the air, two red crescents were thrown out of the mouse's claws again, and rushed straight towards Chen Kai's body. And the big rat itself jumped up and jumped high, and after propping up his legs on the roof, he rushed towards Zhao Tiezhu and them behind.

It's going to kill the mages who stand behind and cast spells, the ones who keep throwing fireballs and missiles because they've made a mess of its fine fur.

But those players who stood in front of the mage would not give way lightly, at least not Zhao Tiezhu. I only saw that he took a deep breath hard, and Xu Fei behind him directly covered his ears, and asked the mages behind him to cover their ears.

A loud "~~~~~ roar" came from under Zhao Tiezhu's metal helmet, and with the violent fluctuations in the air, everyone felt that their ears had been knocked by a big hammer. The indiscriminate attack not only bleeds the ears of the large rat in front of it, but also makes other people uncomfortable.

The loud bang hit the rat's head directly, and as a result, it was stunned by the roar as it pounced forward. Of course, it wasn't that it wanted to be stunned, but it was shocked to its head by the loud roar and the fighting spirit mixed with the sound. It felt that its little head was now occupied by thousands of its own little cubs, and it was very difficult to even move it.

At this moment, a cold light with a white aura rushed straight towards the back of its head, and the big mouse woke up when it was only an inch away from the back of its head. Then it felt a tingling in the back of its head, and it struggled to lunge forward to get away from it. It did, but it was left with a deep wound in the back of the head.

"This rat is too scary, and it can still move even if its brain is injured!" Jones looked through the sight on the crossbow machine and saw a deep wound on the back of the mouse's head, and a trace of red and white substance slowly seeped out, but the mouse did not die, and after rolling on the ground, he pounced towards Su Wan behind him.

It hated the female animal for causing it trouble, and almost killed her. If it weren't for the peculiarities of its body, the attack that pierced its head alone would have paralyzed it to death. Even so, the more than 200,000 vitality was reduced by more than 10,000 the moment it pierced the skull. Of course, it was not that Su Wan's damage reached 10,000, but that the vitality of the rats naturally attenuated by more than 10,000.

"Kill!" Two giant swords swept from the left and right directions, trying to block or even inflict heavy damage on the pursuing rats, and everyone could clearly see the shining fighting spirit on the giant swords.

"Squeak!" A blood-red light flashed in the mouse's eyes, and then it swung its claws and two red fighting qi slashes directly formed, colliding with the sweeping giant sword.

"Bump!" The two crashing sounds came almost at the same time, Chen Kai and Su Xinghe both felt that the weapons in their hands trembled, and the huge power was transmitted from the weapons so that they couldn't hold the weapons, and then the two of them were beaten upside down and flew out at the same time.

Of course, the rat's progress was also stopped, and it saw the dragon spear grow larger in front of its eyes, and then it felt a pain in its open mouth. Everyone saw that the tip of the dragon lance pierced the mouse's mouth and its head, hanging its entire body from the barrel of the spear.

Everyone could see from the team's shared vision a series of massive damage to the rat's head, and the blood-red font that slowly drifted away. "Deadly!" Just two words are enough to make everyone breathe a sigh of relief, because it means the end of the life of the big mouse.

"Damn! This guy is finally dead! Zhao Tiezhu's voice appeared in the team channel, and he himself couldn't speak with his voice because of the roar just now.

"It's better to be careful! Lao Su, Brother Kai is stabbing a few times! Xu Fei looked at the still trembling mouse corpse and said to Chen Kai and Su Xinghe.

"Why don't you poke yourself?" Chen Kai was lying on the ground panting, he didn't even want to move his fingers now, and Su Xinghe was in the same situation not far from him, but it was even more miserable. After all, he was not wearing the same armor as Chen Kai, but a leather armor with steel plates attached.

"Poof! ~" Jones took his dagger and tried to cut the skin of the rat, and the gray fur was probably the most valuable part of the big mouse. Of course, they were also convinced that the rat was dead when Jones cut the fur, and that only the fur of dead creatures would be easily cut.

"It stinks!" Bai Shasha covered her nose hard and hid behind Xu Fei, after the mouse's corpse was cut open, all kinds of things in its body ran out, and the stench quickly spread to the entire room. Even players who have fainted from injuries have woken up from the stench and then fainted again.

"Vomit~~" As the fur completely left the mouse's body, everyone could no longer hold the churning thing in their stomachs, and a large puddle of clear water was spit out. Relative to their body lì value is also consumed a lot, although this consumption is not wanted by everyone.

A violent stench instantly filled the room, and everyone didn't want to stay in it for a moment and fled out, and this stench continued to spread outside the room, it was like the stench of fermented corpses and all kinds of disgusting smells mixed together.

Chen Kai tried to get a few fire elemental mages or water elemental mages to cast spells into the room, scorching the stench with flames, or diluting the smell with water elementals. But when the mages walked to the door with their noses covered, they couldn't hold on, even when the sensory system was turned off. Because that smell can no longer be said to be stinky, but a poisonous gas.

All players will vomit involuntarily as soon as they step through the door, and will not be able to cast any spells at all. And the most important thing is that this poisonous gas is not dispersed by flames or anything else, it is always wrapped there, no matter how many fireballs fly into the wand, it will not burn it, but it will add a scorching smell to it.

"Bad luck! I haven't looked at what makes so many rats in there! Chen Kai looked at the stenching storage room with a pale face, of course, his face was not because of anger but because of the disgusting stench.

"Forget it! Brother Kai should look for other places, right? Why don't you go to the ** area? Xu Fei stood behind Chen Kai and said, to be honest, he really didn't want to spend a lot of effort on some mice, and it was better to look more in the library if he had that time, and see if he could find some useful books that were not taken away.

"Hey~" Chen Kai sighed, he understood that the room couldn't be entered no matter what, unless the disgusting poisonous gas inside was gone. Otherwise, they would have to stop a dozen meters from the door, and let them climb in through the cave where there might be a big rat. Chen Kai himself didn't believe that he would climb, let alone others.

Most of the seven floors of the entire Spell Association were made up of libraries, which was why Chen Kai was in the library as soon as they teleported. Most of the intermediate instructors are actually more often acting as librarians, and in the instructor rank, the mages are more interested in learning various knowledge than increasing their strength.

Of course, many times this librarian is in quotation marks because they spend more time reading books than sorting them out. Therefore, most of the people who manage the books are low-level mages, and they are the best among them.

But now most of the library is empty, and only the lowest-level book section has some shelves that look like books. This area is open to poor and low-level mages in all cities, and is mostly based on the basics of spelling as well as various geographical and dynastic histories.

However, although most of the shelves seem to be full, it is difficult to preserve books that are actually exposed to the air. At least from the sticky books and the various moldy pages, you can see that the books here are basically unreadable.

"Whoa!" When Chen Kai touched the cover of a book, it had already fallen apart directly, if he didn't know that this was a low-level book area, it was estimated that Chen Kai would be uncomfortable to death. Looking at so many books can only be read from a distance, and not being able to take them away is the most depressing thing.

"Look carefully! Hope to find a few useful books! "All the players who can move are looking carefully in front of the dozens of bookshelves, and most of the books have been seen in that spell shop before, so it won't be too uncomfortable for them to scatter if they come across them.

"It's a pity! What a book on the basics of the magic circle! There are only three small pieces of paper left! Lancer sighed as he took the three pieces of torn paper in his hand, and there were only three pieces of paper left in the heavy book wrapped in cowhide for ten pounds. The book was supposed to be placed in the Higher Library area, but it is estimated that some administrator misplaced it, and as a result, the book was lost. The most important thing is that the book has not been preserved, all the paper has been turned into crumbs, and only three pieces of vellum are intact.

"Shall I exchange this half-local vein book with you?" Xu Fei was very greedy for the three pieces of kraft paper in Lanser's hand, and the things that could be written down on kraft paper must be very important, especially the color of the handwriting on them with a hint of silver powder, and it was obvious that there were other things in the ink of the writing.

"Get out! I have the complete Book of Leylines! Or do you exchange that arcane element! Lan Ther knew that Xu Fei had an arcane book that he bought from Chen Kai, and if it wasn't for the high price, he probably would have bought it himself. The cover alone is made of Mithril mixed with other metals, and everyone knows how important and precious the contents are.

"......" Xu Fei glanced at Lan Ther carefully, and then turned around and left directly.

"Don't go! Or I'll add some more money! Lan Ther watched Xu Fei turn around and leave, and hurriedly chased after him, and then he felt a weight under his feet. Only a "tearing" sound was heard, and the mage robe he had managed to get his hands on was finally dead, and it was directly broken by a hook protruding from the bookshelf.

Then everyone heard the clatter of wood breaking, and the creak of something falling, only to see the huge bookshelf above Lancer's head slowly falling towards his head.

"Help!" Lancer barely had time to shout before he was crushed underneath the massive wooden bookshelf.

Everyone heard the loud bang and the long scream. After the bookshelf collapsed, the dust raised was nearly a meter high, and a large number of books were directly blown down by the wind. The remaining pages shattered in an instant under this force, turning them into scraps of paper that floated in the air.

"Help! Help me! Lancer's voice came from the team's channel, waking up all the dazers, and everyone quickly rushed to the collapsed bookshelf to dig out the books and books buried under Lancer. The books and the wooden shelves were heavy, and Lancer had only been crushed under them for a short time, but he had only half a life left.

"The god of spells is above! I was almost crushed to death by a magic book! Lancer lay on the ground wrapped in gauze, and now he was less of a mage and more of a mummy.

"You're in luck! I didn't get crushed by the bookshelf and found a secret door! The two priests crouched beside Lancer and looked at the black stone door that was exposed behind the collapsed bookshelf, and the few remaining knights were trying to pry the stone door open, the material of the stone door was very special, and it seemed to be mixed with some anti-magic metal inside. The fossils in the earth elemental spell are mud, let alone mud, and not even a little stone dust has been melted.

Everyone wanted to know what was behind the stone door, and there must be something good in the room that could be sealed with a slab of anti-magic stone. Although I don't know how the room is sealed, the only thing that can be understood is that it is not completely sealed, otherwise it would not reveal a dark gap.

However, this gap did not make people feel happy, but increased Chen Kai's worries in their hearts. Regardless of whether it is empty or not, one thing is very clear, and that is that the air from outside the guò void can enter. This is very fatal to books, and Chen Kai can imagine that those books are as rotten as the outside.

"Boom!! ~~" With everyone's efforts, the pitch-black stone door slowly opened, but when the stone door opened halfway, everyone heard a click, as if it was some kind of gear jamming sound. Then, no matter how hard he tried, the stone door could no longer be opened, leaving only a gap for one person to enter and exit sideways.

"It's good to make a crack, otherwise it would have been in vain!" Chen Kai held on to Shimen and tried to pant for breath, the so-called strongest ones were not Chen Kai and them.

The entire chamber was filled with the faint smell of ink, and the strong smell of books mold. After smelling that smell, Chen Kai's face changed, and then he sighed. His mind was not full of books, but all kinds of moldy and broken books.

The whole room is only about 20 square meters in size, and the height has reached about 5 meters. Three large bookshelves stand throughout the room, neatly arranged with various books. There was a small copying table next to the bookshelf, with books and paper scattered on it, and an open bottle of ink that had long since dried up, and the faint smell of ink came from the dry inkwell.

"Good stuff! It's a pity that it's already dried up, otherwise this bottle of ink alone would be worth tens of thousands of gold coins! The mages looked at the bottle of ink that had been put away by the person who entered the room first, although the ink had dried up, who knew if it would be able to be used again after adding some water.

"What kind of ink is so expensive?" Carson asked Jones, who was sighing next to him.

"Dragon's blood! And it's the dragon's blood, do you see those golden bloodstains? Jones pointed to the dusty golden specks on the table, "The guy who used to stay here must be super rich, and the dragon's blood ink is so squandered!" ”

"Yes, yes!" Several mages agreed, as they were eager to pry the dried dragon's blood off the table along with the wood.

"That's it! Stop looking at the ink, hurry up and find the book! Chen Kai said to the few mages who were about to pry the table, there were too many books on the shelves and the types were very complex, and the most important thing was that each book had a spell on it. This means that each book has protective spells that you have to unravel in order to take them down.

Seeing this, Chen Kai was both happy and depressed, because there were only three kinds of books with spell protection. One is the special spell book, which is made by the caster himself to use it naturally to be more protected, and the other is the legendary **, which must be unraveled to read, and the last one is the notes of the past mages, in order to record their own knowledge and various records, they will use defensive spells to protect the recorded books.

The mildew smell that Chen Kai had smelled earlier came from the rotten paper on the table, while the real books were safely preserved on the shelves under the protection of protective spells. At least until the spell crystals and crystals around them shattered, the books would not be damaged in any way.

Although Chen Kai really wanted these books to be **, it was obvious that they were not, and if he insisted on saying that they were just books that had been banned by spells. It has nothing to do with the legendary **, but they are indeed the most valuable treasure of all mages, the study notes of those mages.

However, it is not easy to obtain these notes, and each note needs to have the corresponding strength or the corresponding spell protection to be turned on to take it down. No matter which notebook is written in spell ink, even if you don't count the paper, the magic of those notes alone is surprising enough.

Chen Kai really wanted to help open those spell prohibitions and take down all the books on them, but he couldn't help it. Because he's not a mage. Even though he had a little knowledge of spells, he couldn't spell out the structure of spells with magic.

All the spellcasters were trying to spell out some structure with magic to match the patterns that flashed from the books. If you make a mistake, you will be electrocuted or scorched, and if you make a mistake, you will be electrocuted or scorched, and if you make a mistake, you will be killed by a ban in the spell book.
