"That's one gone, two more to go."
Arthur smirked as he saw the falling black ashes of the deceased Vermillion Bird. He expected a huge powerup once the chains were broken, but the amount of power boost he just received is really inconceivable.
Although the matter of dying after 12 hours is still on his mind, he decided to ponder about that imminent problem later on, when the threat of the Divine Beasts is gone for good.
With the Vermillion Bird's death, the other two became terrified as they shrieked and violently shook their bodies in an attempt to get away from this area.
Their fear of the thunder was really genuine, they didn't even put up Arthur in their eyes for they were too focused on the red thunderbolts descending from above.
Fortunately for them, the tribulation seemed to ignore their existence completely, thus sparing them from the thunderbolts which could incinerate them whether they resisted or not.
