"There is the last set of passwords, but we have no books anymore." Xiaoyao looked at the others speechlessly, "I have checked that abbreviation, and it doesn't match the books we have at hand."

"how so?"

The Paparals were the first to jump up.

They couldn't get involved in the work of craftsmen, and the others were fine, but just watched quietly as several people deciphered.

But Parker himself could not hold back his loneliness. He felt that instead of wasting time here, it would be better to go out and fight with the imperial people.

There is nothing in this place, and the treasure that was agreed upon is just some technical documents that he thought were worthless. If there is anything good about those things, even if they are sold, they will not fall into his hands.

Others also looked at Aona.

The girl was a little embarrassed, "Gerdham, Helinwell and Friston left this mechanism just to prevent others from obtaining these technical documents. They did not lock the box, just because they thought it was impossible for anyone to solve these mechanisms. But they did not intentionally leave answers. They took away many books before leaving, including the answer to the mystery, and maybe..."

"Please, ma'am, you said it earlier," Xiaoyao was speechless and spread his hands, "Are we wasting our efforts?"

"It's not going to be a waste of effort," Luo Wei pressed her hand on the book and pondered for a moment, "There is no book here, but not outside. Isn't there any collection of books in the Empire Workshop that is the most complete field of alchemy?"

"Do we have to go there again?"

"No need to be so troublesome," Fang Yu suddenly stood up, making everyone look at him unexpectedly. "No need to find that book. I have already thought of it. "Magic Technology Theory, First Volume", the only technical documents related to pipe-type magic furnaces are left. This book is not here anymore."

"Wait," Xiaoyao suddenly realized something, "You won't...?"

"Sy'ton, Chapter 3, Crystal properties and etheric affinity, A5, paragraph 5, N7, B2, A5, are the letters J, D, M, A7, paragraph 7, B5, B3, C9, are the letters S, A, V."

Fang Yu looked up and looked at Sandao's shocking eyes that were looking at him, "Don't stand there, enter it and take a look. After so long, I'm not sure if what I remember is correct."

Xiaoyao then came to his senses and entered the six letters mechanically.

With a light sound, the universal meter turns counterclockwise, then stops gently, and then the entire dial is opened.

"Damn!" Xiaoyao screamed again, then raised his head and looked at Fang Ling like a monster, "Ed, you can't be that Friston, right? Don't tell me that you are from seven hundred years ago?"

"What are you kidding?" Fang Rong said angrily. However, he did not expect that some of the books he had read in Kapka could come in handy today.

Moreover, since he obtained the Dragon Knight system, his memory has become better and better. He already has extraordinary memory. He completed the basic course of apprenticeship so quickly at Kapka, and he relied on it without relying on the system.

But if you can still remember every line and every word in the book in two years, then he would never have been able to do it in the past, just as if the system had imprinted the knowledge into his mind.

He asked Jita and Luo Yu, and the other people's systems did not seem to be like this. They could call to retrieve from the system, but the knowledge was not imprinted in their own memory.

But Fang Yu himself didn't understand what this meant.

He has always been a pragmatist. As long as he can use it, he will use it first, and then talk about it in such a moment.

However, this obviously shocked Luo Wei and the others. The members of the Seven Seas Brigade were fine. They saw too many magical things on Fang Yu, and they could no longer be so numb.

Even Aona glanced at Fang Yu in surprise.

But she didn't think anything. After all, in my impression, Gerdham, Helinwell and Friston were all geniuses who chose one out of thousands. Because she had seen too many, she was not that strange.

But as the box opened, she couldn't help but hold her breath slightly.

She tried hard to restrain her excitement and said to Fang Ling: "There is another last question, Mr. Ed."

"I saw it, huh...wait, what is this!?" Xiaoyao answered first, but he looked at the dial, and his originally excited expression frozen on his face, and turned into a confused look.

Shui Wuming and Luo Wei also looked at the mechanism under the dial strangely. They had never seen such a bizarre device.

Among all, only Fang Yuran stood up from his position and walked closer to the dial a few steps forward. He looked at the device below, raised his head again, and asked Aona on the side with a little breathing:

"What is this, Ms. Aona?"

"I don't know either," the girl shook her head gently, "I only know that this is the mechanism left by Gerdham. What's wrong, does Mr. Ed know this mechanism?"

Fang Yu closed his eyes and shook his head to deny it.

He does not know this mechanism either.

But it's hard to say that I haven't seen it before...

It was a gray gem, inserted into the crisscrossing pipe network below, like a center, gathering the twinkling starlight here, and a strange layer of light appeared on the surface of the gem.

The light shines and is blurred, like stars.
