Inside the airship, Gila went ahead and examined the twins from top to bottom. Sure enough, with her cultivation being several times higher than the twins, it didn't take long for her to notice Rean and Roan's cultivation.

"Peak Core Formation Realm? Well, that's quite surprising..."

Hearing that, Vio was slightly surprised as he decided to also check their cultivation. "Oh! You're right. They really are at the Peak Core Formation Realm."

Ren Zolfin, who was with them, couldn't help but comment, "This kind of high-level cultivation and young age. Celestial Land?"

Rean and Roan looked at each other, then back at those Zasfins as one of them responded, "The Decadence Region."

Gila nodded in response to their words. "So that's why, huh? Well, it makes sense. If you lived there since young and fought your way through, I can more or less accept this level of cultivation and age. However, I'm surprised that you got to escape from there."

As for Vio, he couldn't care less. "There's no point asking. Whether or not they came from the Decadence Region matters little. The good thing is that their Soul Purity hasn't disappeared while their cultivation is at a high level. If it continues like that, they'll be worth hundreds of human kids as time passes. After all, their lifespan increases with their cultivation."

"That's true." Gila and Ren nodded in agreement.

Gila then stopped paying attention to the twins and simply said, "You can move around as much as you want. Just don't try to leave the airship. Remember that all of us are keeping an eye on you two, so there's no chance for you to escape."

After saying those words, Gila left the room, followed by Vio and Ren. Well, that obviously left Rean and Roan slightly confused. Rean soon said to Roan through their connection, 'It seems like they don't think we can cause any problems even with our cultivation.'

Roan agreed with Rean, replying, 'Indeed. That's a good thing for us, though. Have you noticed? They aren't treating us like most of the Zasfins do. Well, it's not that they're treating us well, but it's just that they simply don't seem to care.'

'Now that you say that...' Rean pondered a bit over their current situation as he spoke his thoughts, 'Other than their interest in our Soul Purity, not even our high cultivation was enough to catch their attention. I thought they would treat us more like some extremely rare treasure that must be kept under surveillance at all times. But that doesn't seem the case.'

'Exactly,' Roan said as he continued, 'That being said, I believe humans at our cultivation level might not be as rare as we've thought so far.'

Rean knew where Roan was coming from. 'It seems like we have the same thoughts. These Celestial Lands are always revered by allowing Zasfins to cultivate much faster than anywhere else other than in the Imperial Families' dwellings. I always thought it was strange since it doesn't change the fact that this planet severely lacks Spiritual Energy.'

Roan nodded, saying, 'Indeed. Think of the Asume Clan Ancestor, who was only at the Soul Forging Realm. Vanesi City is one of the important cities of the entire Palif Empire due to the Rank Five Bloodline Trial. Let alone Soul Forging, there are supposed to be several Saint Realm Zasfins there. Even an Elemental Transformation Realm Zasfin wouldn't be impossible to see there. But even after saying all of that, none of those exist there because of the planet's Spiritual Energy condition.'

Rean and Roan arrived at the same conclusion after that. 'That means there's something special in those Celestial Lands, Imperial Families' Dwellings, and especially in the Soul Rulers' headquarters.'

It was then that Sister Orb's voice echoed in their minds, suggesting to them, [Isn't this guy Clad a member of the Imperial Bloodline? You might as well ask him.]

Rean and Roan had to agree that Sister Orb was right. Following that, the two of them connected their minds to the Dimensional Realm and sent their voice into the jail, asking, 'Clad, we have a question for you.'

Clad, who was feeling quite bored, immediately agreed as he replied, 'Sure! What is it?'

'Can you tell us if the Imperial Family's estate has some kind of high concentration of Spiritual Energy? We mean, some kind of formation or things like that?'

Clad was taken aback for a moment and then began to ponder about it. 'Hmm...as you know, our branch of the Palif Imperial Family was cast away, so I'm not sure about those things since it happened before I was born. However, I did hear my father commenting about something like that before. He said even Rank Four Spirit Stones couldn't compare to having access to the area where the main family members cultivated. Well, I can't guarantee that, though.' While replying to their question, he could not help but think the two should have already known something about that.

Rean and Roan nodded in response to Clad's words before they disconnected from the Dimensional Realm. Not long after, Rean said to Roan, 'It seems there really is something going on in the main powers of this planet.'

Roan then got up as he said, "Forget it. Since we're heading straight to the Soul Rulers' headquarters, we'll eventually find it out. Let's head outside and explore the ship."

Rean's eyes lit up as he said in response, "Then I'm going to the engine room...well, not that I think I'll find an engine, though. Without a doubt, this ship's 'engine' is powered by formations. I want to see how they're made."

Roan couldn't care less as to what Rean did. After all, he was not well-versed in formations. "I'll check the forces around, just in case."

And with that, the twins left the room they were staying in. Of course, they also kept the Spiritual Sense Bending Skill active. That being said, they could see several Spiritual Senses locked on them. If they really tried to escape, there would be no lack of Zasfins coming out to stop them.

'Well, we can simply enter the Dimensional Realm and flee, though,' Rean thought, not minding the vigilance at all.

The ship was enormous. Nevertheless, it wasn't hard for Rean to find the 'engine' room. Surprisingly, the Zasfins in there seemed to ignore Rean completely, only warning him to not touch the formations. The usual disdainful looks that most Zasfins cast at humans was nowhere to be seen on their faces.

Unsurprisingly, Rean ignored that as his attention was completely focused on the formations of the airship. 'Impressive! To think they could use formation in such a manner. I can see many areas that could be improved a lot with my knowledge of formations from Sunkan Planet. Not to mention the Circuitry Formations from the Soul Gem System. Then again, by using Soul Runes to regulate the flow of Spiritual Energy, they were able to make it fly. Soul Runes are really interesting.'

Rean was so focused on those formations that he began to draw them on the floor. Of course, he wasn't using any formation materials, just scribbling them. At the same time, he was fixing the parts that were obviously flawed or had worse efficiency than the runes from Sunkan Planet or the Circuitry Formations.

Some Zasfins saw that and snorted, thinking that Rean was just getting ahead of himself. How could humans truly understand the complexity of their airship formations? However, there was one Zasfin who narrowed his eyes as that Zasfin thought to itself, 'What kind of runes are those? Those are only a few scratches on the ground. However, they don't seem to have been created without reason.'

This Zasfin was none other than the Formation Master responsible for the formations in the airship. He was also a Heaven Middle-Level Formation Master of the Formations Guild.

Eventually, he approached Rean while paying attention to the modifications he made to those formations. Of course, Rean wasn't a Heaven-Level Formation Master, so he was only tinkering with the formations he could deal with. The Heaven-Level parts he didn't even touch.

Out of nowhere, that Zasfin put a hand on Rean's shoulder, which instantly brought him back to reality.

"Ah!" Rean almost jumped when that happened. He was truly focused on the formations of the airship.

The Zasfin then looked at Rean with a serious expression, asking, "Where did you learn about formations?"

Rean noticed that he had gone a little too far, so he tried to come up with an excuse. "Errr...I have the study materials from the Formations Guild from Vanesi City. I was only trying to apply them to these formations. Sorry for making a mess on the ground. I'll clean it up right away."

Rean was just about to use his Spiritual Energy to wipe out the drawing when suddenly, that Zasfin stopped him. "There's no need." He then pulled Rean back before continuing, "I'm very interested in those runes of yours. Does that mean you got them from Vanesi City? Show me those study materials you talked about."

Rean bitterly smiled as he answered, "I don't have them anymore since I already committed everything to mind. However, a few of the runes I used are not present anyway. They're just a few things I came up with."

"Are you saying you created those different runes and thought of the formation arrangement by yourself?" The Zasfin talking to Rean found it really hard to believe. Well, Rean didn't really make a formation, just some random scribbles here and there, so those runes might have no use whatsoever.

Rean scratched the back of his head before continuing, "They're just a few theories. I don't even know which kind of materials I would need to bring my ideas into reality. Hahaha! In the end, I'm just someone who dabbles with formations from time to time. There's no need for senior to pay attention to me."

He then added, "By the way, I'm Rean. I was brought aboard since it seems that I have a very high Soul Purity...although I don't know what that means."

Immediately, the guy's expression changed to that of shock. "High Soul Purity?!"

Sure enough, he didn't expect to hear such a thing from an adult human.
