The Mother of Evil Dragons' divine power shield was quite well-constructed, allowing for a decent shield with minimal divine power consumption.
Unfortunately, it was not enough to withstand Otto's blue fireball, which was enhanced with many special substances.
The blue fireball didn't slow down, and when it collided with the divine power shield, it didn't encounter any significant obstruction.
It was like a fast-moving baseball hitting an ordinary household glass, shattering the divine power shield without any trouble.
The slightly reduced-speed blue fireball showed no mercy, smashing into the Mother of Evil Dragons - specifically, the neck of the Blue Dragon head on her shoulder.
Although the Mother of Evil Dragons' scales were much stronger than those of ordinary dragons, they seemed powerless under Otto's blue fireball.
"Boom!"
