Phantom Veil Grass

As the fight raged on, Korrin's focus sharpened. The intensity in his eyes mirrored the blazing aura surrounding him. He tightened his grip on his fire-infused spiritual power blade, his mind rapidly analyzing Graal's movements.

Despite Korrin's skills and power, Graal's overwhelming strength and versatility kept him on the defensive. 

However, with each exchange, Korrin's experience grew, and he began to anticipate Graal's moves more effectively.

Graal lunged forward, his heavy sword cleaving through the air with incredible speed. 

Korrin sidestepped, narrowly avoiding the blade, and countered with a precise slash of his fire sword, followed by a swirling vortex of fire around him.

Flames trailed behind the weapon, licking at Graal's body. 

"You're persistent, I'll give you that," Graal sneered, his voice dripping with disdain. "But persistence won't save you."
