Barry was a little disappointed and annoyed at the White light being because It didn't say it sooner. But there's nothing he can do about it for now. He now knows about it so he will make the best use of it.
'If I can defeat it with this Shard now, I should be able to defeat it at that time, right? I don't need to go into the Dungeon,' Barry thought.
'Your strength is not strong enough. The Shard is just a little help, it doesn't give you the power to defeat the Essence of Destruction. You still need to raise your own strength,' the White Light said, replying to his complaint.
'Alright.' Barry replied briefly. He actually already suspected that everything was basically based on his own strength.
"Grrhh..." the Essence of Destruction growled again. This time It while walking at him with sure steps but there was something different about it.
