Ghost Domain!

Using the Dark Wing mutated from the Silver Wing as a Sealed Object immediately struck Fang Yuan as a good idea.

After all, although both the Odd Keystone and Light Clay were top-tier materials for making Sealed Objects, they still had not surpassed the category of ordinary materials.

But the Silver Wing was different. Back in the Sea God Temple, it had briefly manifested its own consciousness and even condensed Lugia's phantom with air currents.

A bona fide, high-end legendary-grade material!!

"Bwooo? (Should we do it? ヽ(??▽?)ノ)~~~~?"

"That's not a bad idea, Rotom." The Rotom Phone nodded after hearing it.

"Eevee! (Let's not. (.-_-.))!!!"

"Mm, right... let's forget it."

After thinking it over atop Dragonite's back, Fang Yuan shook his head.

Eevee was right.

He still could not bring himself to turn the Dark Wing into a Sealed Object.

Fang Yuan decided to be cautious.

Because the process of turning material into a Sealed Object required an Aura Messenger to use their own Aura to alter the material's Aura.

Fang Yuan was fairly confident about altering the Aura of ordinary materials, even things like the Odd Keystone and Light Clay, because they were inanimate objects.

Though it consumed strength and time, it was all within Fang Yuan's limits. He was certain his Aura could suppress the Aura of those materials.

But the Dark Wing was different. It was Lugia's feather.

Without Lugia's consent, Fang Yuan reckoned it would be difficult to alter it.

If the Silver Wing had not mutated, Fang Yuan might have dared to try it directly.

But now that it had mutated into the Dark Wing, Fang Yuan was worried he might suffer backlash while altering its Aura.

Put simply, Fang Yuan lacked confidence in his current Aura Power.
