Age of Elves: The Return of the King

To study the energy cube formula by yourself, in addition to requiring the researcher to have a very high level of production and experience, he must also have a certain understanding of the core idea of ​​​​cube production.

Coincidentally, Yun Xiao, who has been making cubes continuously in the two lifetimes and has tasted the artisan-level formula, now meets this condition.

And the remaining problem - time, can also be solved through the time orb.

Based on the above reasons, Yun Xiao immediately made a decision.

——Starting today, use the extra time provided by the time orb to try to research another type of original energy cube!

As for which property..
Among the current team, only Fossil Pterosaurs meet the level requirements, so let's make flying ones first.

He shook his head, took a deep breath, casually threw the materials around him into the machine, and continued to make the rest.

After making a week's worth of cubes, Yun Xiao left Hualan City, and set out for Golden City again as planned.

He began to analyze his current situation.

First of all, the most important event right now must be the upcoming fall of Sirona.

Three weeks from now, this will happen on the Quartz Plateau.

As for Yun Xiao's preparations for this, in addition to the pre-arranged plan to make the basic strength of the fire-breathing dragon reach the top level of the owner before this incident, there is now one more thing.

——Find a way to help the giant fast dragon unlock the seal, and then ask the giant fast dragon to help him once.

In order to do this, Yun Xiao must find a way to learn the sealing technique from thousands of years ago.

But this is not an easy task. With the help of the system, Yun Xiao also failed to find the most critical step to undo the seal of Kuailong.

He couldn't help but think of the information he had obtained.

[Hint: If the mental strength is insufficient when sealing or unsealing, there is also a method that does not need to consume the user's vitality. 】

【That is】

There is a way, but what way?
He frowned slightly, and finally took out the illustration book and called Sirona.

The communication was quickly connected, and Sirona's face was also revealed.

Judging from the on-screen background, she appears to be in the room right now.

"Come back from the ruins?"

Yun Xiao spoke first.

"That's right, it hasn't been long since I came back."

Sirona smiled.

"How is it? Have you read the classic book I sent you? Did it help you?"

Yun Xiao nodded.

"I found someone here to translate it for me. The classics are incomplete, and the most critical information in them is lost."

Sirona froze for a moment.

Originally, she just wanted to give this tome related to the sealing technique to Yun Xiao, so that he could have a general understanding.

After all, even I can only translate part of the content of this classic.

But now Yunxiao actually said that he found someone to translate it for him!
Who is so powerful?
Yun Xiao noticed that Sirona was stunned, and seemed to realize that she had said something she shouldn't have said.

This thing is translated by the system, and the existence of the system must not be explained by itself.

Fortunately, Sirona didn't delve into this point, but directly answered Yun Xiao's question.

"There are incomplete parts of the tome... I really don't know about it. I found this tome when I was exploring a ruin in the Sinnoh area, and I didn't see any other tome fragments at the time."

"Now that ruins have also collapsed into ruins."

When Yun Xiao heard this, her heart sank immediately.

In this way, the most critical clue is broken.
