113 Heaven Destroyer!

A few days passed like that as Rio continuously practiced his newly learned battle technique arts and trained with Helia to understand their profound principles.

On a fine day, two figures, enveloped in blue light, thunder flickering around their body, were chasing each other in the battle arena.

The air around them crackled with lightning. Both were using [Thunder Enchantment] which boosted them to have lightning-fast reflexes and moved their body with incredible speed.

Duo clashed with each other in a blur of fast motion, their beast soul swords radiating through the air as they parried their opponent's attacks and countered one another. 

If there were any spectators It would've been difficult for them to see their action with naked eyes as Rio and Helia were too fast, their swords clashing together in a blur of lightning.

Even after using their exceptional speed, neither of them was able to land a determining blow.
