As Kieran’s attention was focused on the heart, information about the heart popped up in his vision.
[Name: Devil’s Heart]
[Type: Organ]
[Rarity: Epic]
[Attributes: ?]
[Effects: ?]
[Prerequisites: ?]
[Able to bring out of the dungeon: Yes]
[Remarks: This is a heart that once belonged to a Devil Lord!
...
Comparing the information that was given to him, Kieran stared intensely at the heart in the crystal box. His expression was serious.
Not just because of the many question marks he saw, but also because of the sudden change to the heart’s beating.
The change was as obvious as a wild tiger turning into a tame rabbit.
Kieran believed that he would need a special method to keep the heart, but then what?
He didn’t worry anymore. His mind was filled with thoughts about the reason the [Devil’s Heart] was beating differently.
"Why did it change?"
Kieran unconsciously looked through the notification log, but there was no mention of it.
