Kirito led Lyfa and Crompis all the way along the roofs of the town streets, and even stepped on the eaves of the castellan's mansion.

There is a long distance between the roof of the city lord's mansion and the roof of the tall library, but these two buildings are very close to a cliff that is directly used as a city wall. If you can jump on the cliff, you can use it as a bridge to the roof of the library.

"Brother, you can't go up this section no matter what?" Lyfa said, looking up at the cliff.

As for why not just climb the wall of the library—the library and the mountain where the cliff is located are integrated, and there is no place to climb. If you can do it, you have already done it.

"It's really not good with our current level and the skills we have mastered. I have tried many times before (during the beta test) and failed, but the lady owner will definitely do it." Kirito said confidently.

"Why do I feel like a young lady whose family doesn't agree with dating comes out to find a wild man for a tryst?" Crohnpiss muttered, jumped up the cliff, and summoned vines to pull the siblings up too.

"However, only this side of the city wall doesn't have any patrols and sentry posts. It's a bit careless. It's true that the cliff is very strong, but if a small group of surprise soldiers attack..." Kirito took it for granted because he was doing the "Elf War" mission. Mention this.

"Then, you can walk over there with your eyes closed, to ensure that you can return to the first floor after a sense of weightlessness. As for whether you are still alive, that's another matter, hehe." Amused.

"Huh? Is this the edge of the map?!" Since this is an unexplored area plus outside the circle, most of the system map is shrouded in black mist.

In short, let's put aside the war and focus on the clues of the previous Hamburg line.

When they approached the direction of the library, Lyfa smelled it again and said, "It has the same hamburger steak smell, and it seems to be mixed with the smell of smoke."

"That's right." Kirito followed the scent, found a very narrow square opening with a ladder, and said, "Well, it should be possible to go down from here."

"This is? Why is there a passage here?" Lyfa asked.

"If you burn hamburger steak in a secret room, I think there must be a chimney or a vent somewhere. There is a ladder here. It seems that even the method of cleaning the inner wall is prepared. Sao is really persistent in this regard." Kirito laughed. road.

Crohnpiss put her hands on her hips and said, "You go down first."

"Me?"

"If it's a chimney, what's the point of going down and sitting in a pot or on a fire?"

"Uh, alright, I'll go down and have a look first, and I'll send a letter after confirming it's safe...Use [The Art of Distant Books] to inform Lyfa to tell you." After finishing speaking, Kirito carefully climbed down from the square opening.

Lyfa: "Hey... Can you really complete the mission by messing around without following the mission flow?"

Kirito: "The smell of that hamburger steak is the hint itself, so there is a high possibility that this is the answer?"

Crohnpiss: "No, no, with the personality of the old man who only likes to eat meat but hates vegetables and fruits, I think this is just a secret tooth sacrifice for himself, and has nothing to do with the Chamber of Secrets."

But now that it has been done, it would be a pity not to try it. If it is a normal game, it will definitely not work, but Crohnpiss is also very interested in the results of Kirito's novel brain circuit.

After a while, Kirito sent back the message "Safe, be sure to come down".

………………………

A group of people who were still busy playing the puzzle game, seeing Kirito who got into the secret room through the vent and opened the door from the inside, were speechless to the extreme.

But then they can only temporarily enter the so-called viewing mode.

"Master Bhurum, long time no see."

"Hehe, isn't this little girl Crampis, who actually drilled into the air vent of my house with this little human bastard, you have changed." The person who said this was a man in a black robe with deep wrinkles on his face, wearing a Small round glasses, a dark elf old man with a long white beard.

Obviously dressed like a profound sage, his tone and body language are very lively.

"Who told you to change the mechanism outside?"

"Hehehe, the old man heard that some people have established a mutual aid relationship with Lyusla. Since they are going to participate in the war, with the arrogant and rigid personalities of those priests and high-level officials, there must be many things that they have nothing to say. They will use the human race until it is drained. Then The best place to get what you need is the only library in Lyusla, and this old man is going to test their eligibility."

"So, is the kid who drilled the vent qualified?"

"It's very clever to think of this method. It's very useful to catch the loopholes in the tight defense. Think about it again, little girl Clampis, can you make foreign friends?"

"Heh, how is it possible?" Crohnpiss took off Little Red Riding Hood's hood and cloak, revealing illusory human ears, then she stretched out her hand and took off a ring on her hand, showing the appearance of a fairy, and walked to the shadow of the bookshelf Inside, fiddle with the books above.

"This is—" Argo walked a few steps to look at Cloen Piss, and beckoned to Tongren, "Tongzi, come and have a look."

Kirito moved over and was also slightly shocked, and the two began to chat secretly—

[The pv released before the official release of "Swordartonline", the silhouette of the boss who didn't show his face near the end, is it very similar to this? 】

[Could it be that we originally wanted to find a branch line to improve our strength, but accidentally ran into the main line? 】

[The official setting is the original fallen goblin, the object of the fallen goblin's faith that attacked Tong Zai and your group. 】

[No, it's just a picture. Fallen fairies are enemies of all other races, right? Even if there is a plot where we are used by the villain ~lightnovelpub.net~ it is strange that we have a good relationship with the great sage Bhulum. 】

【Do you know this old man? 】

[I saw it during the beta test, but at that time there was no such a complicated library, let alone a hamburger steak, it was just an npc in our common sense. It's better not to see them as the same person. 】

[Tong Zai, then you can ask directly, after all, you were the first to trigger the plot here. 】

"Excuse me," Kirito stepped forward and said, "Could it be, Miss Shopkeeper, you are the original fall..."

He couldn't go on talking for a while, because Crohnpith gave him a harsh look, which made him worry about whether there would be a silencing plot, and subconsciously looked for the file loading button.

Cloenpiss sighed pretendingly, and said: "Although I do have that title, I don't like it. Originally, I hoped that you would concentrate on accepting the trial of this great sage first. The long-term observation of adventurers, you should be people who pay more attention to what you can get than the cause and effect. If you want to know more, you may be confused and not help your practice, where should I start?"
