"Roar!"
The Elite Siren, after being blasted away and standing up, let out a fierce roar as if relaying some message. The other Elite Sirens, upon hearing it, slightly changed their gaze in their eyes and collectively turned to Robin before charging out.
"Block them!" Robin shouted, and the other apprentices quickly launched their spells.
"Swoosh swoosh swoosh!"
"Swoosh swoosh swoosh!"
"Boom boom boom!"
Beams of light flew out, striking the chests of the attacking Elite Sirens and then bursting open. Amidst the torrential rain, there were explosive roars and fleeting flashes of firelight.
The Elite Sirens stumbled and tottered, their attack speed slowed down.
After seeing this, Robin slightly relaxed and then his gaze sharpened. He reached into his collar and violently pulled out a necklace worn around his neck. The necklace had a green stone hanging from it, resembling a miniature green heart.
Gripping the stone tightly, Robin shouted and recited the spell amidst the storm.
