Finally, there was Human Realm Power.
This was somewhat of a riddle. Mainly, Human Realm Power seemed to be the power of Teyvat's people. Broadly speaking, anything related to humans could be counted as part of Human Realm Power.
For example, the gentle elemental power used by Visions counted as Human Realm Power, as well as things like willpower…
Thinking again, the Traveler was called the Child of Humanity and possessed the power to purify the Abyss or, in other words, contain the Abyss…?
Hmm. Interesting.
Then there was one more very interesting point. The pinnacle of Light Realm Power—the Seven Dragon Sovereigns—had been subdued by the pinnacle of Human Realm Power.
It was hard to say specifically what powerful aspects Human Realm Power had.
But from the perspective of its manifestation, Human Realm Power could use the powers of both Light Realm Power and Void Realm Power.
To put the relationship of the Three Realms' Power more vividly…
It was probably that Light Realm Power and Void Realm Power fought each other to the death, while Human Realm Power played the role of mediator in between.
However, mediating also seemed to require strength. If one's strength was insufficient and one suffered a backlash, that was also very normal.
For example, people without a Vision who tried to control pure elemental power would suffer a backlash. A Vision, acting as an external magical organ, helped harmonize the elements.
What Cid was currently learning was attempting to bypass the Vision as an intermediary to study and safely use Light Realm Power.
In Cid's estimation, if he achieved success in his studies later on, he might be able to freely control all seven elemental powers like a certain Traveler.
"Eula, help me keep my Vision for now. I also need to get used to life without a Vision."
Eula accepted the old uncle's dimmed Vision.
"This is…?"
"If I'm going to Enkanomiya, I can't bring a Vision. That place has too poor compatibility with Visions. If they come into contact, it's easy for an explosion to occur."
Little Eula gripped the old uncle's Vision tightly.
"Without a Vision, going to Enkanomiya would be far too dangerous, wouldn't it? Although you said you know what's down there, Old Uncle… but you're also following the people of the Abyss Order…"
"That's right. So next, Old Uncle here also has to make proper preparations. This kind of adventure where no one can provide a safety net—this old uncle hasn't experienced it in a long time either."
Little Eula sighed.
"I knew I couldn't stop you, Old Uncle. Do you need my help?"
"Help me prepare some adventure supplies. I'll have to use the backpack again."
"Hmm… Alright."
Under normal circumstances, this journey shouldn't have any accidents.
Unless they ran into that blond Dainsleif.
But he probably wouldn't appear on Watatsumi Island.
He was always tracking the traces of the Abyss Order…
Hiss…
Fluffy Fire-san, do you think your Prince would sell you out?
Hmm. It shouldn't be a big problem. Anyway, if they couldn't win, they could only let Fluffy Fire-san be the hilichurl traitor when they met.
"Right, Little Eula. If you encounter a blond man wearing a single eyepatch and luxurious formal attire while the Enkanomiya seal is in place, just let him in if he wants to enter Enkanomiya. His identity is special. He can serve as Old Uncle's teammate."
"Understood. I got it."
No matter what, evening time always felt very long.
And it was also when the human brain was most flexible.
However, it was still recommended not to stay up late.
Staying up too much would make one's head foggy.
The old uncle had also officially begun enjoying life after losing his Vision.
Hmm… Before, he had simply felt that his perception of elements had weakened a lot.
But now, although his perception of elements had become worse, his perception of other things seemed to have become more detailed.
For example, the feeling when waving his hand, the beating of his heart while breathing, and the movement of his muscles during activity…
Previously, when he had elemental power, his perception had been focused on the outside world. After losing it, he instead paid more attention to his own body.
