"You'll solve it so quickly?"

Half an hour after leaving, Yue Yulou slowly walked back to the city. Before the people at the city gate had dispersed, they were shocked when they saw him, especially Medusa Susan, because she knew that the things that could destroy a team of harps in an instant would never be any weak creature.

"Well... I solved it, it's just a nightmare, this is its scales..."

Yue Yulou took out a reddish-brown plate-like object similar to iron sheets and handed it to Susan, which he asked the Nightmare Knight to give him the assignment.

"Is Nightmare... very powerful?"

Susan looked at the things in her hands carefully, because the harp was dead, and she had no idea what kind of creature was attacking them.

"On average... it's just a third-level low-level creature, but it's very fast, and it's really a big threat to the harp."

"That's right...will it happen again in the future?"

"It probably won't be possible. That nightmare came here because of an accident..."

Susan then breathed a sigh of relief with confidence, and then smiled at Yue Yulou:

"Master Safi, you have helped us in the city of Never Sleeping. This is the reward you deserve..."

After saying that, she handed a purse and a pair of boots to Yue Yulou.

"Players complete missions: threats from the center of the earth, reputation of the city never sleeps +10."

"Players receive mission rewards: gold coins x10, Earth Center Wanderer."

"Ground Center Wanderer (Boot), Level 3 Magic Item, Dexterity +10, Action Speed ​​+2.5, Unhealthy Terrain's hindrance on the character's action speed -35%, Player's action speed in the Underground World +50%, Requirement: None, Weight: 0.07kg"

After everyone gradually dispersed, Yue Yulou planned to go back to the hotel to rest for a while, but Evil Eye Kunshak obviously didn't want him to rest so quickly.

"Safi Spell, can you do me a favor..."

"Hmm? What's wrong?"

"This... I am the library administrator of the City of Never Sleeping, but since no outsiders have ever been here, I am not a evil eye who likes to throw books around, but sometimes I will turn the library a little messed up in order to study some things... The library is already a mess now, and it is said that more outsiders will come in a short time. If the Queen knows about the library now... I dare not tell others, so I can only ask Safi Spell, you can help me sort it out. OK..."

At this time, Kunshak's tone was like a child who broke the glass but was afraid of being discovered by adults. Several tentacles were constantly tucked together. The huge one-eyed eye did not dare to look at Yue Yulou, but kept scanning the empty ground.

"Haha, OK... I'll just go and help you."

"Really! Master Safi thanks so much. I will definitely pay you a satisfactory reward!"

"Player accepts mission: Khunshak's help, mission reward: unknown."

Then Yue Yulou and Kunshak came to the huge Tupiao Astronomy that never sleeps almost covered the entire library, and the messiness of the library was obviously not just "some" as Kunshak said. The bookcases were crooked and the books were scattered all over the floor... The entire library seemed to have experienced a tornado.

"Ahem...Kunshak, I feel that this place is much more serious than what you said..."

As soon as he stepped into Tupiao Astronomy... he began to regret taking on this task.

"That... Master Safi, it's just a little dirty here... I'll find someone to do the cleaning work. You just need to help me place the books. After all, some books were originally in high positions and I couldn't reach them..."

Yue Yulou had no choice but to sigh helplessly, and then began to clean up the books on the ground with Kunshak. Not long after, the other evil eyes also came to the library with a few brooms to start cleaning. For a moment, the entire library became dusty...

In this way, Yue Yulou spent two days helping Kunshak clean the library. He did almost nothing in the past two days, but during this period he received a communication from Lan Zhiyou. In the communication, he told Yue Yulou that he was already level 3. Yue Yulou asked Lan Zhiyou to go to the Silver City-State to wait for him, and said that he would pass soon...

"Huh...it's finally done! Master Safi, I'm so grateful to you..."

After Kunshak put the last book in his hand into the bookshelf, he looked at the relatively neat library, and then nodded with satisfaction. Yue Yulou, who was beside it, breathed a sigh of relief. He had never felt so bored...

"Uh... it's okay."

"Master Safi, in order to feel your help to me in the past two days, I decided to give you a good thing! Your mage will definitely like it."

After saying that, Kunshak ordered Yue Yulou to a small room on the second floor of the library, and then carefully took out a heavy book from a secret compartment in the room, and then handed it to Yue Yulou.

"This is something I accidentally discovered. It seems to record a mysterious spell array, but I can't understand the text above, and our evil eyes have bad magical talents... So, I will give it to you, maybe it will be useful to you..."

"Players complete the mission: Kunshak's help, the reputation of the city never sleeps +1."

"Players receive mission rewards: "Introduction to Extreme Compression of Phase Folding Spell Arrays"

After Yue Yulou took this book that seemed very profound, he suddenly felt deceived, because since this book was from ancient times, the words on it would be ancient words. Although Yue Yulou had some understanding of the words, he was not strong enough to understand the words of a disappearing civilization...

"Well... let's take a look at what's above."

Yue Yulou slowly opened the book. Just as he put his hand on the page, a stinging pain came into his brain, and at the same time, some strange words slowly appeared in his mind...

"The player's 'awakening' skill is activated and he has obtained the new skill 'mysterious language'..."

"Master Safi, what's wrong with you?"

Kunshak found that the moment Yue Yulou opened the pages, his expression became very painful, so he immediately walked to him and supported him.

"It's okay...but, I can understand this book..."

With the help of Kunshak, Yue Yulou slowly sat on a chair and smiled and turned over the pages of the book again. The content on it began to appear in his mind...

"It's so terrible... I didn't expect that people could create such a magic array... How powerful should the strong men in that world be!"

Half an hour later, Yue Yulou only barely understood the previous pages, but these simple pages really scared him because the book records a spell array with gods. Targeting gods does not mean that this spell array is used to kill gods, but that this spell array can make the caster control everything like a god... The principle of the array sounds very simple, that is, the caster draws a spell array that can fold space on the ground, and then can influence a fixed area through the array. For example, if you pat your hand gently on the array, the locked area will look like a huge earthquake... And the array introduced in this book has another huge benefit, that even if it wants to affect a huge area, the array you want to draw does not need to be too large, which is the meaning of extreme compression...

However, the whole process is very difficult to actually operate. The drawing of the array of folded space alone is extremely cumbersome, and it requires a huge amount of energy to be consumed during the drawing process and cannot be disturbed... It is best not to have other too strong energy in the locked area, which will weaken the effect of the array to a certain extent... The drawing of this array requires a very high requirement for the drawer's space magic cultivation, and it must be someone who can open the door of the dimension at any time... And this technology is actually very profound. Yue Yulou felt a headache after just looking at it for a while.

"Oh... go back to the hotel and watch it slowly..."
Chapter completed!
