Alex commanded, "Remember, you must strike simultaneously. No mistakes!"
"Yes!" the three girls responded in unison, quickly moving to their respective positions.
Wendy clasped her hands together, chanting a spell under her breath. A golden light enveloped the luminous pearl on the left side.
Isabella held her Frost Sword, pointing its tip at the pearl on the right.
Mila gathered a stream of energy, aiming it at the target above.
"Ready... fire!" Alex ordered in a deep voice.
In an instant, the golden light, sword energy, and airflow struck the three luminous pearls simultaneously, causing them to glow brightly and illuminate the entire hall!
At the same time, the silver patterns on the boulder sparkled with dazzling light, swirling around its surface.
With a thunderous roar, the entire tower shook!
Countless stones crumbled from the walls, clattering to the ground.
"We did it!" Isabella exclaimed joyfully.
