Since then, Gu Qinyan has been haunted by Nadya's monster robbery, holding his arms all the way and making awkward appearances, feeling as if his favorite dish that he had saved until the end had been robbed. However, everyone didn't bother to pay attention to him, and continued to move forward, and everyone was immersed in the fun of the game at this time.

"Let's ...... next" Nadya asked, Gu Qinyan, Liu Yiyu, Zhang Zinuo and others hurriedly raised their hands in unison to try to stop her, "No, no, no!" Don't ask! ”

But the second half of Nadya's sentence still blurted out subconsciously: "Where to go?" ”

"Oh, no......" Gu Qinyan covered his forehead helplessly, Liu Yiyu and Pei Pei were also a little helpless, and Xia Chiyu said as a matter of course: "Of course I went to find the library here, if I don't know the history of the dwarf clan first, how can I complete this mission?" ”

Gu Qinyan sighed on the side, obviously expecting Xia Chiyu to say this, Liu Yiyu also smiled bitterly: "Although the words are so, we are very bored when you read the information......"

"Then why don't you go and clean up the monsters around here, I'll just go to the library alone, and I don't need someone to be a bodyguard anyway." Xia Chiyu doesn't care.

"I'm going with the fish." Nadya immediately raised her hand and said positively, "I also want to see how boring it is to go to the library with the fish." ”

"......Whatever you want," Xia Chiyu said with a dry smile, secretly dissatisfied: in the end, it was not for the materials he got from the library that it was easier to kill the boss and complete the task, but these people would cross the river and tear down the bridge.

So Xia Chiyu and Nadya came to the dwarf's National Library, while Gu Qinyan led Zhang Zinuo and others to clean up the nearby monsters. Of course, there are actually quite a few strange monsters in the library.

The dwarven cities are so majestic, and the National Library is certainly not much smaller, and the building is almost the size of a gymnasium. At the entrance stands a statue of a Libra, flanked by books and gold, as if to imply that knowledge is money. But the books of the dwarves record most of the techniques of forging and metallurgy.

"National Historical ...... 6 blocks in Zone C. Xia Chiyu came to the door, checked the classification and said to himself.

The library has only one floor and is divided into five areas of ABCDE. There are twenty bookcases in each district. However, the library is also littered with monsters infected by the Corrupt Plague.

The effect of the Corrupting Plague on these monsters is not the same as that of the dwarves, with monsters increasing in size, greatly increasing their aggressiveness, and being oddly shaped. Xia Chiyu and Najia had just arrived in Area A, and after advancing for a while, several strange white worms appeared in front of them, blocking their way.

The white worm resembles a maggot, white and chubby, but grows on the ground like a plant. The lower half of the body was sunk under the floor, and the head was covered with red tentacles, like blooming chrysanthemums, constantly wriggling, and the worms themselves were constantly swaying back and forth, like mutants of some kind of coral.

"It's disgusting...... Nadya suddenly frowned, and without waiting for Xia Chiyu to make a statement, she immediately raised her hand to these worms and shouted, "Ice Age." Absolute zero! ”

The hoarfrost instantly enveloped the worms, freezing them into an ice sculpture. But the worms were still trembling, trying to break free from the freeze, and then Nadya raised her index finger and shouted, "Ice Spear!" ”

A water droplet flew out, and the worm, which had been frozen into an ice sculpture, instantly shattered, turned into broken ice all over the ground, and gradually melted.

"The damage is so high......" Xia Chiyu secretly smacked his tongue. Enemies in the frozen state will only be reduced to a piece of ice when killed, otherwise the monster will only recover from the frozen state. This is not only because Nadya has an artifact, Xia Chiyu guessed that it was probably because of the hot environment in this place, so the monster's frost resistance is very low and the fire resistance is very high.

Nadya raised her foot to kick the broken ice on the ground away, and walked through Area A with Xia Chiyu. Then come to Zone B.

"The dwarves have magic?" Nadya couldn't help but be surprised when she looked at the books in Area B, grabbed a "Lava Magic Extra" from it, and opened it to take a look, but the book had just been opened, and two scorpion-like insects quickly crawled out of the pages and jumped into Nadya's hand, Nadya screamed, quickly shook her hand, and then turned her head and threw herself into Xia Chiyu's arms.

"Y-What are you doing!" Nadya immediately came back to her senses and slapped Xia Chiyu in the face.

"I didn't even understand what was going on, so I was slapped in the face...... Xia Chiyu rubbed the place where he was hit on his face and said with a dry smile, Nadya looked like she had been violated. Immediately, Xia Chiyu picked up the book from the ground and flipped through it, and found that the so-called lava magic was a special dual-system spell formed by fusing fire and earth magic.

This is different from Xia Chiyu's multi-system spell, Xia Chiyu's multi-system spell is a combination of two elements, but the fusion of these two elements into a "lava element", Xia Chiyu guessed that this should be a spell used by a new class unique to the dwarf clan.

"I warn you, if you touch me again, you'll kill you." Nadya covered her chest and glared at Xia Chiyu vigilantly.

"Yes...... I'll try to avoid you. The corners of Xia Chiyu's mouth twitched, and he threw the book aside.

After clearing out some monsters like spiders and mice, they came to the national history column. Xia Chiyu began to flip through this part of the book to learn about the history of the dwarf clan. This is very important, as their mission is not only to find the lava core, but also to investigate the source of this corrupting plague.

First of all, the lava core is the main item that the dwarves rely on for their function, and it will definitely be hidden in some hidden location, and in such a large city, it will waste a lot of time to search aimlessly.

In addition, the Corruption Plague originated more than a thousand years ago, and the Dwarves abandoned the old town of Ezes hundreds of years after the Corruption Plague broke out, so there must be some relevant records in the history of the country, such as the time when the plague appeared, the approximate location, and the characteristics of the plague, so that they can investigate the source of the plague outbreak and deal with the monsters infected by the plague.

Xia Chiyu held his chin and flipped through the books, he paced back and forth in the area, carefully looking at the information recorded in the books, and Nadya asked, "What is written on it?" ”

"Hmm......" Xia Chiyu just groaned, and didn't seem to hear what Nadya said.

Seeing that Xia Chiyu was so serious and ignored him. Nadya puffed out her cheeks a little upset, and wandered around.

It turns out that under the royal palace of Ezes, there is a complex mechanism, and the core of the lava is actually the core of this mechanism, to put it bluntly, the underfloor heating and energy supply device. Convert the heat of lava into energy to provide magical energy to the entire city. This energy is used for lighting, blacksmithing, metallurgy, and the "magic devices" of the dwarves.

Based on the magic circle created by the new class "Array Mage" in the previous version, various household utensils are crafted. For example, the magic circle of cooling, the magic circle of lighting, and the magic machine. To put it bluntly, magic tools are household appliances, and magic machines are mechanical tools such as excavators and cars, but the energy that makes these appliances run is magic.

It can be said that the dwarves were able to develop the city so prosperous with the power of the lava core, and the whole of Ezes was built with the help of these magical machines, without the lava core. The Dwarves are just a bunch of miners, and with the Lava Core, the Dwarves become engineers.

Thinking about it like this, Xia Chiyu recalled that he had indeed seen some very strange devices on the road before, he originally thought it was some kind of strange statue, but now that he thinks about it, it should be a magic machine. The structure of those magical machines is unique, with the upper body resembling a humanoid. The shape varies depending on the function, and there is one responsible for transporting. There are also those used for mining.

And the lower part of the magic machine, which should be the position of the legs, is a strange sphere, glowing with a dark blue metallic luster, which makes people wonder how to stand with such a lower body.

However, if you look closely, you can find out. There are some strange "tracks" scattered on the ground of the city, and the lower part of the spheres of these robots move along these tracks. These orbits are the devices that power the core of the lava.

"It's easy this way, just follow these tracks...... Xia Chiyu thought to himself, and then grabbed another book, titled "The Underground World of Ezes - The Crystallization of Dwarven Wisdom".

The book records the approximate structure and location of the energy supply system beneath Azes. In addition, there are some gods who can't understand and understand the useless principle of the operation of the energy supply device, to put it bluntly, it is thermal power generation. Xia Chiyu recorded the contents of the book first, planning to take it out and read it later when he was looking for the lava core.

Immediately, Xia Chiyu continued to shake in front of the bookshelf, trying to find information on the corrupt plague, but there are very few records of the corrupt plague in the history of the country, only indicating the time of the outbreak of the plague and the evil consequences it brings.

"Well, it doesn't seem like there's anything useful in this place, so let's go to the medicine bar." Xia Chiyu turned to Nadya behind him and said, but when he turned around, he found that Nadya didn't know where to run.

"Okay, I'll go alone." Xia Chiyu shrugged his shoulders, and then walked towards Area D alone.

In the medicine column, Xia Chiyu really found a lot of detailed records about the corrupt plague, including the location of the initial outbreak of the corrupt plague, the time of the outbreak, as well as the symptoms, the mode of infection, and how to avoid being infected.

The Corrupt Plague first broke out at coordinates 63, 55, and 20 of the Abyssal Pit, known to the Dwarves as the "Forbidden Pit". Legend has it that there is another world deep underground, which has its own unique food chain and circulation, called the "forbidden world", and the pit of the abyss is actually the periphery of this forbidden world, similar to the existence of a "wall".

The dwarves have passed down this taboo from generation to generation.

Unknown creatures live in the forbidden world, and due to the harsh living environment, the creatures there are also extremely powerful, and of course, there are unknown diseases. The diseases that can infect these powerful creatures are naturally terrifying.

The disease of the Corrupt Plague is only transmitted through blood, that is, the wound is transmitted after contact with the pathogen, while the germs of the Corrupt Plague only exist in the "putrid fluid" secreted by the infected, as long as the putref fluid is not in contact with the wound, even if it is attacked by the infected, it will not be infected.

However, once infected, there is no cure, and this plague germ is able to survive in any environment, but the activity of the germ is significantly reduced in cold environments. Infected individuals will gradually lose their minds and will not be able to control their anger, leaving only aggressive and bloodthirsty **, repeating hunting and eating until the carrier dies.

However, a conclusion was also produced after the trial. The plague does not appear to infect terrestrial creatures.

Human beings are naturally also included in the creatures on the ground, so Xia Chiyu and the others don't have to worry about being infected by this plague.

However, Xia Chiyu frequently saw a name from these books, the greatest doctor of the dwarf clan "Archer Bruce", all of which were written based on Archer Bruce's medical research records.

It is recorded that the doctor sought to find out the cause of the outbreak of the Corrupt Plague and how it was treated. Traveled to the "Forbidden Lands" where the plague broke out, but never returned.

"In this way, the information should be enough......" Xia Chiyu looked at the recorded information and nodded, "That's it, find Nadya's girl, and then prepare to find the lava core." ”

At this time, "Boom! A dull roar sounded, and Xia Chiyu suddenly felt a chill behind him.

"How many times have I said that......" A shrill whisper rang out from all directions. Then a huge arm swept horizontally, Xia Chiyu was startled and stretched out the mental force field, but the fat and white arm swept directly on his mental force field, and a powerful impact force came to his face, and Xia Chiyu flew out with the human spirit force field.

A heavy impact came from behind, and Xia Chiyu smashed three or four bookshelves before he barely stopped, and slowly stood up from the old stacks of books. A large black shadow emerged from ahead.

This creature was supposed to be a dwarf before. But now there was almost no shadow of the dwarf, it was like an immensely large baby, fat, with stubby and fat limbs, supporting its fat body.

Its body is white, fat, and hairless. The veins on the top of its bare head burst out, its expression was hideous, and a large amount of blood erupted around its eye sockets, which made it look even more angry.

"Mogtu, the infected librarian," emerges from above the creature's head, roaring in that shrill voice, "Books in the National Library." It is only for reading, and it is forbidden to take it out of the library! ”

Its shrill voice pierced Xia Chiyu's eardrums, and then Mogetu waved his hands and slapped it at Xia Chiyu.

Xia Chiyu took a step forward and snatched into its arms, raised his hand and pressed it on Mogetu's chest, and shouted, "Thunderstorm burial!" ”

Thunder and lightning quickly spread from Mogtu's chest, and Mogtu screamed, trembling and entering a state of paralysis, but his health was reduced by less than five percent. It quickly adapted to the thunder and lightning, and the expression on its face became even more angry, and it opened its mouth to bite Xia Chiyu. Xia Chiyu used the stand-in to go directly behind Mogetu, and then ran out of the library.

The place was too cramped and dim for the mage to fight, and he had to go outside. After all, Mogetu is also a level 80 boss monster, so you can't underestimate it. However, what made Xia Chiyu strange was that this librarian had been infected by the Corrupt Plague, but he still seemed to have retained a certain amount of sanity, and was not as completely crazy as the infected people they had seen before.

Usually infected people don't even have the ability to speak, and they don't have any memories of when they were normal people, but they just brainlessly attack any creature that is not an infected.

However, Mogtu, the librarian, can not only speak, but also clearly remember that the National Library forbade books to be taken out of the library, which I don't know if it was a game bug or if it was originally set that way.

"Books from the National Library are forbidden to be taken out of the library! It is forbidden to take it out of the library! Seeing that Xia Chiyu was about to run outside the library, Mogetu seemed to be berserk, chasing after Xia Chiyu frantically, dancing the big windmill with both hands, and relying on this way to move forward quickly while hammering the ground, chasing after him. This situation is full of oppression in combination with Mogetu's appearance.

"I'll it......" Xia Chiyu cursed secretly, turned in mid-air, and stretched out his hand to press on the ground: "Rashomon!" ”

"Boom!" With a bang, a gate with a demon pattern on the door appeared behind him, blocking Mogetu. Mogetu didn't hesitate to hit his head on it. However, Rashomon is a high-level multi-system spell, and its effect is much stronger than ordinary spells, so although there was a huge shock, it still stands, temporarily blocking Mogetu's advance.

However, Rashomon itself is impregnable, but the foundation that supports Rashomon is not. Under Mogutu's impact, Rashomon slid backwards several meters under the ground. And Mogetu didn't give up there, banging frantically behind Rashomon, while letting out a sharp and piercing roar, pushing Rashomon to keep retreating.

"Damn, where's Nadya's girl?" Xia Chiyu muttered to himself angrily, looked around, but didn't find Nadya's shadow. After thinking about it, Nadya is the four kings after all, and I believe that she can be safe without taking care of herself, and now the librarian's goal is him, and leaving the library with this boss should be the best choice.

Therefore, Xia Chiyu turned his head, ran out according to the previous route, and quickly came to Area A, where the door of the library was close in front of him. At this moment, a huge black shadow suddenly flashed out from his left front, blocking his path horizontally.

"Books from the National Library are forbidden to be taken out of the library! It is forbidden to take it out of the library! Mogetu roared, grabbed a boulder from the ground and threw it at Xia Chiyu's side. Xia Chiyu waved his hand and threw a flame explosion technique to blast the gravel into pieces, but Mogetu's speed was completely disproportionate to its size, and the next moment it came to Xia Chiyu through the smoke screen of the explosion.

"Violators are punished by death!" Mogetu screamed, clenching his fists with both hands and slamming them on the top of Xia Chiyu's head. Xia Chiyu knew that with his spiritual force field, he couldn't compete with the attack of this boss, so he directly raised his hand and shouted: "The Seraphic Angel of the End!" ”

The golden aperture spread out, and it was able to block Mogetu's blow. After using the Seraph's enhanced spiritual force field to block this, Xia Chiyu raised his hand and drew a triangle in the air, and the back of the angel outside his body also danced with the long sword.

"Six stars break through the sky, light binding!" Xia Chiyu shouted, and at the same time, another voice also sounded: "Ice Age, Dragon's Breath!" ”

A cold wind erupted from Xia Chiyu's right back, engulfing Mogetu's figure in an instant. When the cold wind dissipated, Mogetu was completely frozen under the restraint of the six lightsabers and the freezing of the cold wind.

"Where have you been?" Xia Chiyu asked Nadya, who came up.

"You're so fascinated by it, I'll go and walk around myself to see if there's a hidden room or something." Nadya replied lightly.

"Anyway, let's go out first, it's a bit disadvantageous to fight this guy in this place." Xia Chiyu said angrily, running towards the door of the library, Nadya looked at Mogetu curiously and asked, "Is it infected?" Why can you still talk? ”

"I want to know too." Xia Chiyu laughed dryly, and the two had already run to the door of the library.

At this time, Mogetu suddenly took a deep breath, and then screamed in the sky, its voice was already shrill and piercing, under this hoarse scream, Xia Chiyu only felt dizzy, his eardrum tingled, he was nauseous, and he couldn't move a single step. He pulled Nadya back and returned to the library.

In this way, Mogetu finally stopped screaming, but it had also broken free, its expression looked more angry than before, and its body was slightly reddened, as if it had entered a rage. It approached Xia Chiyu and Nadya step by step, and hissed, "The books of the National Library...... It is forbidden to take it out of the library...... Forbidden—Taken Out—Library! ”

"What a madman!" Nadya frowned slightly, covered her ears and said in disgust, "Isn't this to let us out?" ”

"yes, it should be." Xia Chiyu sighed and said, "We can only fight it here." ”

And Mogetu's body was even redder than before, and while walking towards Xia Chiyu and Nadya, it was babbling, and its voice became thicker and thicker, gradually becoming thicker and thicker: "It is forbidden to take books out of the library, it is forbidden to destroy the books in the library, it is forbidden to copy or assist the books in the library without consent, and it is forbidden to ......"

"Let's fix it first." Nadya smiled confidently, applied ice to herself, and then circled around Mogetu, raised her hand to leave a white mist in midair, and then clenched her small hand: "Absolute zero, chakra!" ”

The circle of white mist quickly turned into a circle of cold ice, tightening towards Mogetu, and Mogetu's fat and bloated body was suddenly squeezed as if it was about to explode. And Mogetu retched twice, and suddenly opened his mouth to spit out a large mouthful of yellow-green mucus to Xia Chiyu and Nadya (to be continued. )
