When the old mermaid arrived in the city, the first thing they did was to build an empire, and then built a magic tower in the center of the city, which was called the Imperial Palace.

"At this time, there should still be residents in the city, and the old man and mermaid alone can't build this magic tower!" Gu Xiaofei said secretly, "Not only that, the Crystal Palace should have been very prosperous at that time!" Magic Towers are not something that anyone can build! ”

In addition to the basic materials, professional craftsmen, enchanters, and even alchemists are also required, and after the construction is completed, the interior also needs to be reprocessed by the enchanter, commonly known as decoration.

After the palace was built, the old mermaid also held a celebration, and then there was a palace dance and so on, which can be described as a prosperity.

Later, the timeline is hundreds of years later.

This year, Jiaer is here!

The old mermaid has no heirs, and because of her advanced age, the Sea King can only send one more heir over, so strictly speaking, the old mermaid is actually Jia'er's sister, but the age difference is a bit big.

And when it came to the second year of Jiaer's arrival, an incident happened, Jiaer heard that there was a banshee living in the city, and he was immediately angry, and immediately ordered the banshee to be driven out of the city.

"What's going on?" The corners of Gu Xiaofei's mouth twitched, and something came to mind in his dark.

Flipping back, there are any major events recorded in the chronicle, which are basically summarized in one sentence, and it is not changed until the last two pages, only to see that it is written: There is a human magician from the land who has visited, and has become the apprentice of Princess Jiaer and a part-time court magician......

"Why does Gar hate banshees so much?"

After reading the chronicle, Gu Xiaofei frowned, although the banshee and the mermaid have become two races, there is no obvious contradiction and conflict between the two races, most of the undersea cities are willing to accept the banshee, and there is even a special formation composed of banshees in the army under the Sea King.

"Let's see." Gu Xiaofei rubbed his eyebrows, it had been more than a hundred years ago to drive away the banshee, and there should be no need to contact the disappearance of city residents.

After flipping through the basic historical records again, Gu Xiaofei shook his head, there were some official clichés on it, and there was nothing he wanted.

But because of this, Gu Xiaofei's brows widened.

"I kind of understand, this chronicle is a fake one! I didn't expect the sea tribe to like to play this routine too. Gu Xiaofei smiled and shook his head, he estimated that the chronicle should have been deliberately tampered with, so there should be a real chronicle that has not been tampered with!

The reason why he was so sure was mainly because he had been in the library of the Ancient Moon Empire for a while, and there were two chronicles there, one was true and the other was fake!

The real one is written by the secretary elf, and everything recorded on it is true for every emperor to see, and the fake one is naturally for those officials and ordinary people to see, the content on it has been tampered with, and some things that can't wait for the table have all been harmonized!

"Found it, there!" Gu Xiaofei glanced around, and immediately found that a bookshelf was out of place with the 'companion' next to him, presumably there was a secret door, and it should be a real chronicle or some other valuables inside!

After knowing this, Gu Xiaofei didn't look for the switch of the secret door in the library, after all, this is a magic tower, there are many mechanisms, and there must be an early warning magic on such an important item, which will be triggered as soon as it is touched, then his plan will be terminated.

Exiting the library, Gu Xiaofei stretched out, and when he was about to go down the stairs, he glanced at Jiaer's bedroom, and then ...... Then he slipped in.

"The fake chronicle says that Gal drove the banshee, which may be true, and the disappearance of the city residents in the back also has a lot to do with her, maybe you can find something inside!" Gu Xiaofei found an excuse to break in.

Gil's room was very ordinary, with a large shell bed, a dressing cabinet, and very simple. There was a window next to the bed, from which you could look down on half of the Crystal Palace.

Gu Xiaofei walked to the dresser, checked the drawers, and found a large pile of letters in one of the drawers.

"Letter from Mother!" Gu Xiaofei raised his eyebrows, don't look at the piles of Haiwang's children, but there is only one wife, because of this, the letter from the queen of the sea is very valuable, and Jia Er can receive the letter, which shows that the relationship between mother and daughter is very good.

But the question is, why was Jiaer assigned to such a place with such a good relationship? You must know that this is a secondary fief (in the case of the previous fiefdom did not die, a piece of land is then distributed to another person called a secondary fief), if it is not for the temper of Jia Er and the old man fish is not bad, otherwise the two fish will have to fight!

Gu Xiaofei put the letter back after reading the payment of the envelope, and then went out after walking around the boudoir for a while.

"That's all there is to it, other clues are too deep to dig, and it's very dangerous." Gu Xiaofei went downstairs while thinking, and when he passed by the laboratory on the way, he glanced inside, the old mermaid was teaching Jia Er some magic formulas, and he was teaching it very seriously.

Gu Xiaofei took a deep breath, this task is so difficult, all kinds of clues can't be connected, and now I can only see that there is nothing to gain from the other side!

"How are you doing?" Gu Xiaofei asked in the team channel.

"No gains, these NPCs are all fragmented, it's weird." Xiaoice grains are the first to open.

"I don't have it here, I just found a few NPCs walking repeatedly, and the system won't cut corners to this extent, which can only further indicate that these NPCs were deliberately created by someone." Said bitterly.

"I found an abandoned prison outside the city, would you like to take a look?"

At this time, Feiyang's news made Gu Xiaofei's eyes light up, "But there is a level 35 boss guarding the prison door, you remember to mark it at the spring." ”

"Wow, there's a boss! Come now! Feilan big brother opening certificate! Xiaoice said excitedly.

"Meet at the grocery store."

After sending the news, Gu Xiaofei hurried to the grocery store, Xiaoice and Dacheng, and Bitter Si were already waiting here.

"Let's go."

After opening a certificate for the three of them to go to the spring to mark it, the four of them swam out of the crystal palace together and came to the door to meet Feiyang.

"This way!" Feiyang waved his hand and led the way.

The group advanced along the city wall, then turned into a sea trench next to the city wall, and then in the light of the flying ocean skill, the four of them fell to a bulge next to it.

"If you go inside, there will be a large space, and there is a big boss wandering there, but it is too dark, and I can only see the red name and level." Feiyang said.

"And how do you know this is a prison?" Gu Xiaofei asked.

"After entering, you will not be discovered by the boss if you stick to the wall on the left, and you can touch the pillars at the end, so I guess it's a prison!" Feiyang explained.

"I see, you guys wait here first, I'll go in and have a look."

With that, Gu Xiaofei walked towards the cave.

Feiyang can't see, it doesn't mean he can't see, you know, he wears cat's eye glasses and has night vision.

"Big brother be careful!"

"Hmm!"

Gu Xiaofei nodded, and disappeared into the dark hole in the blink of an eye.
