However, just as they thought the danger had passed, the clear sky was suddenly blanketed by enormous dark clouds. Like a black mountain, the clouds pressed heavily above their heads, filling them with an indescribable oppression.
Then, dazzling bolts of lightning tore through the clouds, accompanied by deafening thunder, as though the entire world had been ripped apart in that instant. Amid the chaos, a massive shadow slowly descended from the clouds.
The shadow grew clearer and clearer, until everyone finally saw its true form—it was an Ancient Fierce Beast as huge as a mountain! Its entire body was pitch-black, radiating an aura that chilled them to the bone. Its body was incomparably enormous, and every step made the ground tremble, as if the earth itself shook at its arrival.
The beast opened its blood-filled maw and let out a deafening roar. The roar echoed through the air like thunder, making their eardrums ache. Even the earth itself seemed to tremble.
Facing such a terrifying beast, the boy's gaze sharpened. Without hesitation, he shouted, "Everyone, be careful! This beast won't be easy to deal with!" Before his words had faded, the immortal sword in his hand flared brightly and shot toward the beast like a meteor.
The other companions refused to be outdone and unleashed their own unique spells. For a moment, countless lights intertwined, forming a brilliant, multicolored line of defense as they launched a fierce, heart-stopping battle against the beast.
The battle was exceptionally brutal. Though everyone resisted with all their strength, the beast was simply too powerful, and their resistance gradually became strained. Wounds covered every body, blood continuously flowing from them and staining their clothes red.
Yet at that critical moment, the immortal sword seemed to answer some mysterious summons and erupted with even greater radiance.
