------------------------ dividing line-------------------------

"Shhhh Be quiet! Chen Kai let go of the crutches in his hand and slowly climbed to the exit of the tunnel. Before crawling out, he gave a note to the players behind him, as they were chattering and whispering.

"Old Su! Old Sue! Chen Kai shouted softly outside a few times under the tunnel, and then saw a hand reach in from the outside, grabbing his hand and pulling him up.

Chen Kai entered a slightly dim place from a dark environment, the surrounding environment seemed unusually dim, through those faint lights, Chen Kai could clearly see the huge bookshelves around him that were three meters high.

The faint scent of sandalwood in the air mixed with the slightest smell of decay made people feel unusually uncomfortable, which was much better than the murky air in the tunnel.

Although the people below wanted to come out of the tunnel, there were not many people in the whole room, and those bookshelves took up so much space that Chen Kai could only walk out of the tunnel with his body sideways.

Beneath a lodging bookshelf was a shattered skeleton with fresh marks of crumbling on its skull. Obviously, he had just been killed, and he was killed by Su Xinghe and a few of them who climbed out in front of them to explore the way.

"Lockyd's Astrology? Is there such a book here? Chen Kai carefully pulled out a book from the shelf, and after checking the cover, he found that it was actually a basic reading book for a star warlock.

"Whoa!" Chen Kai just wanted to open the cover of the book, but found that all the pages inside had fallen off at once, turning into broken and rotten paper.

"......" Chen Kai looked at the book in his hand blankly, the basic reading of the Star Warlock is very rare, because this is a profession that is very rare among the aborigines. PS: A little bit more than the holy sacrifice kind!

"Boss! Why don't you open it yet, and take the book down and look for it slowly? Boser looked at the books that had turned into a pile of rotten paper and said to Chen Kai.

“…… All right! Chen Kai thought about it, and he could only do this, if he picked out one by one, he didn't know how long it would take for these dozen bookcases to be picked out. Staying on it for a minute longer would be more dangerous, and who knows if a few bone mages would go crazy and run around here.

Although there was not much space in the whole house, there were a lot of books, and of course Chen Kai knew that this was definitely not the library of the Spell Association. Because even the Spell Society of Adolic has a collection of more than 100,000 books alone, and there are also a large number of rare books and magic books.

Although there are many shelves here, many of the books are the same printing plates, or different engraving plates. For example, the book of astrology that Chen Kai had just broken up, he found more than a dozen books that were exactly the same, as well as more than two dozen books with different covers.

However, due to the poor preservation environment, many books are still moldy or eaten by insects. Chen Kai found several magic books that recorded spells and spells, and when he turned over them, he saw a large group of black ants working them.

After an hour, the room was empty, and most of the shelves that had been piled up with books were empty. It looked unusually lonely and terrifying in the dark sky, at least Chen Kai and the others were not willing to stay in this room for even half a minute longer.

After packing up all the books that could be picked up completely, Chen Kai and the others quickly went down to the tunnel and re-covered the floor tile at the entrance of the tunnel. The entire bookstore soon fell silent again, only a few hours later, the skeleton crushed under the shelves under the force of filth slowly coalesced and formed.

It pushed open its empty bookshelf and slowly climbed up from the ground. After checking around the bookshelves, he slowly walked along a gap to the front of the room, where five or six low-level bone mages were gathered at this time.

In the front room, the shelves were littered with spellcasting materials that had been messed up everywhere, and the ground was covered in a thick layer of dust with some rotten wooden wands that had been half-reduced to mud.

The red flames in the eyes of those low-level bone mages suddenly lit up when they saw the bones that came out, and then they fell silent again. They slowly followed the footsteps of the low-level skeleton and walked to the entrance of the tunnel where Chen Kai and the others left, and after carefully examining the ground, they slowly walked to the bookshelf on the side and leaned there.

The heads of these low-level bone mages were staring directly at the stone slab at the entrance of the tunnel, and the pairs of red, flame-like eyes slowly fell silent. The whole room is officially plunged into silence, although it is a terrible tranquility.

At this time, under the room and a few hundred meters to the southwest, Chen Kai and the others were slowly taking out all the books. Dozens of mages, magicians, priests, and so on were ecstatic and kept copying the pages of the book that could be shattered at the slightest touch.

For the caster class, especially the accumulation of knowledge of the mage class, determines how many spells they can learn. Moreover, this accumulation is transformed into a kind of knowledge accumulated in certain experiences, such as the experience level of arcane knowledge, which represents the basis for an arcanist to be able to learn several levels of spells. The higher the level of the spell, the higher the amount of knowledge required.

Of course, this is also related to the level of the character itself, even if his knowledge reaches the mentor level, if his own level is only the second order, he still can't learn the spells of the mentor level. Because he didn't have the magic to support the formation of the spell structure.

For melee players, the most important thing that restricts their progress, apart from level, is not weapon experience, nor physical combat experience, but the lack of advanced martial arts. For example, there is a big difference between the player's own Douqi Slash and the aborigines', even among the aborigines, there is a big gap between the effect of the Douqi Slash and the amount of Douqi consumed.

It's not that the Native Mentor can't teach the regular version of Douqi Slash, but that needs to be done after the player reaches the third tier. It would also be a good thing for the player to master this skill himself, at least it would be easier for him. After the player masters the Dou Qi Slash, he can learn some skills from the mentor to enhance the power of the Dou Qi Slash, of course, he still needs to reach the third level.

However, in addition to being able to learn martial arts techniques from their mentors, they can also be obtained through guò books and other means, and can sometimes be more unique and effective than what their own mentors teach.

Therefore, in addition to those mages who were working hard to copy books, Chen Kai and his knights and swordsmen were also working hard to find martial arts books. Chen Kai and the others also found two intermediate fighting spirit cheats in a large number of books, and this kind of popular cheats made Chen Kai and them very happy.

Because finding the first book means finding the other one, this kind of popular cheats can be learned by everyone. The premise is that he has mastered the basic Dou Qi, and if he does not master the Dou Qi, then he may not be able to learn.

However, it seems that the work of copying the cheats can only be done by mages, and those mages are busy copying those useful knowledge for themselves, obviously not having time to help the warriors copy the cheats of vindictiveness. After all, copying a book requires a lot of time and effort, as well as a certain amount of magic.

A second-order mage can copy a book with a maximum of about 100,000 words in an hour, and needs to rest for three hours. The total number of books related to magic knowledge that Chen Kai and the others brought back was no less than three hundred, and if a mage needed to copy them all, it would take him at least five days.

However, each mage can only carry a maximum of ten books to copy, so they need to choose the books they need to copy, and everyone must allocate the books they want to copy and the books they have to copy, so that they can copy all the books in a short time.

As for the other books, it is estimated that they can only be copied after they are brought back, after all, the mage's writing materials are limited and the time is very tight.

"Whew~ I've finally finished copying it!" Lancer grabbed the flat rustle of paper away from the quill, and as soon as he tried to get up and stood up, he found the two knights looking at him with pity on their faces. They had a mid-level vindictive book in their hands, and it was clear that they were trying to find Lancer to copy the book.

"That's it! Don't bother Lancer, all the mages need to rest now, and we have more important things to do. Don't forget that above the tunnel is the entire Asdog's Spell Society, and think of the riches of those High Mages! Stacks of Mithril and Adamantite, piles of gold and gold, magical weapons and scrolls! What you need to do now is not to copy these mid-level vindictive books, but to get some sleep, then clear your backpack and prepare for that big fortune! Chen Kai patted the two knights on the shoulders and said, and when he finished speaking, everyone remembered the video circulating on the Internet of the Divine Knights opening the door of the treasure house.

It is said that the Knights of Shenyao have acquired a wealth worth more than 50 million gold coins, not counting the incalculable value of spell materials and equipment. Thinking of this, everyone's eyes were a little red, and their breathing began to become heavy.

Because they were less than a few hundred meters away from a treasure trove, and that treasure trove might be on top of their heads, at least at the end of the tunnel.

The next day, when Chen Kai was awakened from the game by the alarm clock he had set for the time, the sky of Adogh was still shrouded in darkness. As for Chen Kai, who was accustomed to the dim environment underground, he slowly groped his way to light the candles, and then woke up the others in the tent.

In the center of the basement, the fire that brought the light had been completely extinguished, leaving only a faint red glow shining. Soon after, orange flames rekindled above the looming ashes, a faint glow that dispelled the darkness of the basement and gradually woke up the players who were still snoring.

"Looks like I shouldn't have said those things last night!" Chen Kai looked at a few players who crawled out of the tent with red eyes and said this in his heart, obviously they were all excited and didn't sleep well all night.

"If I were you, I'd wash your face first! Don't get distracted when you encounter a monster, and be careful to be sent back to the temple when the time comes. Chen Kai pointed to a few players with tired expressions on their faces.

Although the system will allow the player to be in a state of deep sleep when resting, the player will also want to rest. If the player doesn't want to rest or can't sleep, the system can't force him to sleep, even if the system has this feature.

Finally rested and recuperated, except for a few injuries that were more serious, such as broken bones, and still needed to rest in the basement and could not join the battle, everyone was ready, and then followed Chen Kai into the deep underground passage.

The distance of a few hundred meters is very short for those who are eager to make a fortune, at least Chen Kai quickly ran towards the tunnel entrance under the impetus of those players behind him. However, the closer he got to that tunnel entrance, the more unsteady Chen Kai felt in his heart, even if the players behind him were eagerly pushing him, his speed was still getting slower and slower.

"Old Su! How do I always feel a little flustered! Chen Kai said to Su Xinghe behind him in front of the oblique upward passage.

"It's okay if you don't mention it, but when you mention it, I feel a little wrong, it's really too smooth!" Su Xinghe thought of the books they obtained, and according to the value assessment in the game, the pile of books alone was worth at least tens of thousands of gold coins. Although the books are tattered and rotten, and cannot be read without being copied, they can still be read on their own.

Being able to be read does not mean that the knowledge in the manual is not lost, even if the whole book becomes a flying scrap of paper after reading, it is at least after it is read.

Chen Kai and the others did not have any obstacle to obtaining this knowledge at all, the only obstacle was just a skeleton crushed under the bookshelf. Thinking of the skeleton that was crushed underneath and killed, Su Xinghe suddenly remembered something.

"Xiao Kai! How long does it take for a low-level grey skeleton to be revived? Su Xinghe grabbed Chen Kai's hand and asked, who wanted to climb up.

"About 6 hours!" Chen Kai thought for a while and replied, this is not the actual time, in many places, because of the rich Cheng dù of the filthy aura, the resurrection time of the bones is also long.

"Then we'll have to be careful! It is estimated that the skeleton that was killed should have come back to life, and crawled out of the place where it was pressed! Su Xinghe looked at the dark tunnel and said to Chen Kai.

Because they had taken the books that had been pressed against the bones in order to collect them, and without the weight of those books, it was impossible for a decaying bookshelf to hold the bones down, even if the other party was a gray skeleton.

"Then I'll observe!" Chen Kai cautiously climbed to the entrance of the tunnel, his eyes slowly appeared a faint starlight, which was the image activated by the eye of the stars.

"No! The surrounding filth was so strong that it was all black in sight! Chen Kai carefully observed for a long time but found that after activating the Eye of the Stars, he didn't see anything he wanted to see, and because of the strong filthy aura around him, the Eye of the Stars couldn't observe any special evil aura at all.

"Su Wan! Come and take a look! Chen Kai thought for a moment and asked Su Wan, who was in the middle of the team, to come to the front to take a look, but the result of her observation was still the same as Chen Kai's, and the filthy aura was as strong as Chen Kai's, which hindered all the divine techniques of detecting evil, and Su Wan only looked at it for a second and felt a tingling pain around her eyes.

"Looks like we can only try our luck!" Chen Kai immediately asked Su Wan to stop observing, he didn't want Su Wan's eyes to be hurt in any way.

Chen Kai held his breath and carefully pushed the floor tiles above his head slowly upward, and he carefully observed the surrounding environment with the Ring of Light through the gaps under the tiles. There was still a skeleton pressed under the collapsed bookshelf, but the head was already intact, and he was staring at Chen Kai under the floor tiles with red eyes.

"Whew! Looks like that guy's bones are completely rotten! Chen Kai breathed a sigh of relief, and then slowly pushed the floor tiles on the top away, and at this moment, he suddenly felt a scorching breath coming from the top of his head.

"!" Chen Kai only had time to curse the word, and then quickly retreated into the tunnel, and five or six huge fireballs were shooting towards his head above him.

"Boom!" A loud explosion rang out through the tunnels, accompanied by scorching flames and flashes of light.

Chen Kai was blown directly from the ten-meter-long passage to the bottom of the passage by the huge impact force accompanied by the explosive power of the fireball. Fortunately, there are a lot of meat shields behind him, but he has also become someone else's meat shield.

He felt like his whole body was already roasted, at least the front was almost fully cooked. If it weren't for his HP of up to 1500 points, it is estimated that just that moment would have been enough to make him return to the temple at once!

But even if Chen Kai's HP was far higher than that of an average player, that moment just now made him suffer close to a thousand points of spell impact damage and burn damage. This is not the case of a frontal hit, if it is a head-on hit, it is estimated that Chen Kai will definitely return to the temple to be resurrected.

"Boss! Are you okay! All the players who were pressed under Chen Kai only received a little bit of burn damage, and they quickly got up and dragged Chen Kai under the passage. Because after those fireballs exploded, a few more fireballs roared into the tunnel, and Zhao Tiezhu, who was behind, quickly carried the shield and blocked the entrance of the tunnel, blocking the attacks of those spells.

"I'm fine! But if you step on my finger again, I'll be fine! Chen Kai pointed to the finger that Fei Yun stepped on and said.

"Sorry! I'm sorry! Fei Yun hurriedly moved the foot that was stepping on Chen Kai's fingers, if it wasn't for the protection of the hand armor, it is estimated that Chen Kai's fingers would have been stepped on by Fei Yun.

"What bad luck! There are at least five Fire Elemental Bone Mages on it! Chen Kai shook his hand, and then quickly poured a bottle of holy water. A trace of cool breath slowly flowed in his body, and then Chen Kai took out the burn cream configured by He Liwen and spread it evenly on his body, which would make his injury heal faster.

As long as you quickly take out the healing medicine for this kind of spell damage and heal the damage, the damage will be faster than the physical damage. With Chen Kai's injury, as long as he was able to continue fighting in half an hour, of course, the recovery of his health might be a little slower.
