Accompanied by a dull rumbling sound, the stone door slowly slid open to the left and right, as if the underground air that had been silent for a long time resumed its flow, and a pungent smell mixed with the smell of decay hit your face.

Fang couldn't help but take a step back, and at the same time looked at the triangular stone slab recessed into the stone wall.

The designer behind this stone door must be an alchemist, and operating it requires a certain amount of parallel abilities, so it's no wonder that the three people were busy here for a long time and didn't open the door.

But he didn't feel so lucky.

Fang was silent for a moment, looking at the dark entrance, and thought in his mind, what if the descendants of Flor stopped here.

What about Eve?

Could it be that I really guessed wrong?

He couldn't help but look at the elf lady beside him. Attila also looked at the entrance of the dark hole and reminded him: "Be careful, Ed."

Fang nodded.

Having already arrived at this place, it was naturally impossible to turn back without success. He had to go in and take a look. Besides, Eve also mentioned that he should come to the underground of the city hall. There might always be some clues below.

The reinforced gloves on his hands made a buzzing sound, the brass gears and hinges were gently rotating, and the internal transmission devices of the two angels also buzzed as they entered side by side with him.

After the initial rotten smell dissipated, only the thick smell of dust remained in the darkness, as if there were countless fine dust suspended in the air, and one breath would fill the entire lungs.

He couldn't help but cough once or twice.

But like an echo, a similarly hollow cough echoed from afar.

Fang was horrified. He subconsciously looked forward and saw that the darkness could not form a fog in front of his eyes. The underground passage was just a gray color.

But deep in the corridor, there was nothing.

Just when he thought it was his delusion, he suddenly heard another faint sigh, like a ghost's sigh, echoing throughout the underground.

Fang was shocked and threw the lighting crystal in that direction, but the light source fell across an arc, splashing up a cloud of dust.

Apart from that, there is nothing.

Attila also walked forward while holding on to the wall.

"Did you hear that, Miss Attila?" Fang stared at that place for a while, then turned around and asked.

Miss Elf nodded.

Fang was certain in his heart that this meant that this was not his own hallucination. He looked up and around, and it seemed that there was really something underneath the city hall.

At this time, his communication crystal lit up.

He stretched out his hand and pressed it. After a moment, Luo Lin's voice came from inside:

"Ed, I've asked. In several directions, no one has seen people of Flo's descent passing through the defense area, but I can't guarantee that they didn't take other ways."

Fang was silent for a moment, he actually already knew this.

"Is the opponent's dragon knight still on the battlefield?"

There was some surprise on the other side: "Dragon Knight?"

Fang nodded.

"Still, do you care about this?"

"No, thanks, Luo Lin."

"You're welcome," Luo Lin smiled: "I just hope that next time we meet, it won't be a life-and-death struggle."

But Fang couldn't answer this question. Considering his relationship with the Dragon Worship Cult, this is very possible.

He silently extinguished the communication crystal.

The dragon knights descended from Flor are still on the battlefield, so unless the opponent invests two dragon knights at once, it means that the dragon knight he saw before has left the underground.

The other party didn't seem to go to the city hall as he expected.

The previous opponents with very average strength levels seemed to be just a small group of people descended from Flor who were very ordinary on this battlefield.

At least it's definitely not as strong as the elite.

So now it seems very doubtful whether the other party's core purpose is really this city hall.

Luo Lin's words at this moment confirmed this point.

But if someone who wasn’t a descendant of Flor took Eve away, who would it be?

Is it an air pirate?

It doesn't look like it. If it was really an air pirate, Luo Lin would not reveal any information to him. What's more, judging from the other party's previous behavior with Pudra, the air pirate should have no idea about the underground seal.

.

That means there is someone else.

Who could it be?

Fang thought as he walked forward. In the midst of his random thoughts, he entered a dusty hall. This was not actually the underground of the city hall, but just a warehouse on the first floor below the main building.

Rows of wooden shelves that have long been carbonized and decayed are covered with gray dust. Some of them can still tell their former shapes, which are rolls of parchment.

Just touch it with your hand and it immediately turns into fly ash and weathers into powder.

It seems that this place is used to store Idos city chronicles, population and household registration documents, etc. This is the basis for the kingdom's rule over a region.

But this foundation, together with these fly ash, has long lost the value of existence.

As Fang walked forward through a thick layer of dust, he felt no pity for these mountains of documents.

The documents and files left here are only the least important part. Countless archaeologists have already visited the underground here and took away a large number of records about Idos.

Today's understanding of this ancient city comes from these documents.

He pushed gently with his hand, and a carbonized shelf collapsed with a clattering sound, and a cloud of dust flew up. He fanned it with his hand, took out his diary, and prepared to figure out which way he should go.

But then Miss Tata appeared in front of him.

"Mr. Knight, I have accomplished something."

"?"

She gently swiped her hand, and with the help of the system's power, three parallel pages of light flew out and appeared in front of him.

A lot of information appeared on it, which was exactly the same as what was described in the diary in his hand. Even if he looked carefully, it was more detailed and accurate.

"I retrieved the information in the log from your previous battle," Miss Tata's emerald green eyes reflected the light page, and she replied very calmly:

"Based on the many descriptions of the community, I redrawn the topographic map here. The top one of these three pages of plans is a reconstruction of the building location on the surface of the city hall."

"The middle picture is the area we are currently in. The one below should be the area recorded in the log. I compared most of the credible accounts and added the above details."

"So I can deduce that we should be directly below the Archon's Office, where the archives are. There is a rotunda of unknown purpose below us."

"According to the description in the log, this hall should be the entrance to the next floor."

"And ahead is the underground prison of the city hall. Through that place, there is a road leading there."

Fang looked at his little lady and couldn't help but open his mouth.

"Tata, Miss Tata, Dragon Soul are all as capable as you...how did you do it?"

"I don't know about that, Mr. Knight," Tata's voice was as calm as water: "But at least so far, I haven't seen any suggestion that dragon souls can be connected to the community."

"No," Fang just sighed a little, but was amused by the other party's serious answer: "Isn't that diary always in my arms? How did Miss Tata see it?"

Tata pointed to his head: "Memory."

"What Mr. Knight sees is what Tata sees, and what Mr. Knight thinks is what Tata thinks," Tata replied: "Mr. Knight, have you forgotten?"

"By the way, when you saw Miss Miya's pointed ears move, her blood pressure rose several points," Tata said seriously: "I don't understand why, but please pay attention, Mr. Knight."

Fang suddenly wanted to slap himself.

What stupid question am I asking? I know that Miss Tata doesn't understand the feelings between people.

He turned around in embarrassment and looked at Miss Attila.

Miss Elf was funny and angry, and praised Tata: "Tata is really good."

"Thank you for the compliment." Tata bowed to Miss Elf gracefully.

"Anyway, let's go to the front first..." Fang hesitated and changed the subject.

Fortunately, Aitila is not Tianlan. If that little French girl were here, she would probably make a fuss about him until he was as big as one.

Miss Elf didn't want him to be too embarrassed, so she just smiled gently and stopped mentioning it.

The two of them, plus a cat and her two attendants, grabbed the hair on Miss Delise's collar and followed Nini, who was walking beside her.

And Miss Tata, who was flying aside, walked forward together.

After passing through the warehouse, there is a long corridor ahead, with a staircase going down from above. That should be the passage from the city hall to the underground building.

But it has collapsed for an unknown amount of time.

Everyone crossed the passage and continued walking forward. Soon, a rusty iron fence appeared in front of them.

The putrid smell here is getting stronger and stronger, as if the blood of the prisoners who died unjustly in the black jail many years ago has not dried up yet.
