“Hmph, my dumb big sister is in danger!”
A mischievous grin spread across his face. “Hehehehe... this gives me the perfect excuse to finally use this treasure I’ve acquired but never bothered with!”
He rummaged through his belongings, carefully selecting various items. “A bit of this... and this... and a dash of this.”
Boom!
The explosion of energy sent a ripple through the air as he laughed maniacally.
“Hahaha! It's done! Now, all I need is a compatible host for it.”

Before the boss could react, Asher dashed forward, conjuring a blood spear in an instant. With a precise strike, he pierced the Phantom King's chest—only for the spear to pass through like mist.

The Phantom King chuckled. "Clever. But not clever enough."

Asher didn't reply. He simply closed his eyes.

A thin line of blood ran down his arm as he reopened his eyes. The void shattered like glass, revealing the true battlefield once more.
