Karna's gaze met the sand elemental's, his determination was unwavering. He knew that this would be their greatest test yet, a battle against a formidable opponent. Gripping his Kusanagi tightly, he prepared himself for the fight.
The sand elemental roared, sending shockwaves through the desert. It launched an onslaught of sand projectiles towards Karna and Shaurya, testing their reflexes and agility. Karna swiftly deflected the projectiles with his blade, his movements a blur of steel.
Shaurya leapt into action, dodging the sand projectiles with his incredible speed. He lunged at the sand elemental, his fangs and claws tearing through its shifting form. But the sand elemental proved elusive, constantly morphing and regenerating, making it difficult to land a decisive blow.
