"Mysterious Crack" 

But Code-L looked like a fool when drawing invisible circles in the air, and the Hydra couldn't bear to tell her the truth. 

Thus, as a wise legendary beast, he just shut his mouth and ignored Code-L. 

Still, deep down, he doubted Code-L's ability and felt such an ability might be a fluke. 

Unfortunately, the Hydra was bound to be slapped in the face. 

Just after he thought Code-L was a bit silly and unreliable, the whole battlefield suddenly shook greatly as if someone held the ten elder's domain and shook it hard! 

GRAK. GRAK. GRAK. 

The entire domain seemed to be shaking so much that the ocean was about to be tossed upside down, replacing the sky above everyone's head. 

The void itself started to tremble fiercely, and even the mid-level Valkyries had to control their Pegasus tightly to avoid being shaken to death. 

The space was trembling, and the sound of something boiling echoed throughout the domain.
