Capítulo 774: Black Turtle God Beast

'My spirit heart is hidden within the damaged core, but to get there, you will have to find a way to reach the main city that has been buried deep underground, Master.'

"I see," Leon uttered.

According to what he knew, everyone in the Divine Realm regarded the artifact's heart and core as one and the same thing.

This is due to the fact that the core comprises the main runic circuits, while the heart is just one component of the core. 

Nevertheless, the heart isn't always formed within the core.

The heart of artifact spirits is the essence of their existence, usually formed through the crystallization of energy near the power source, which can be within or outside of the core.

And to make an artifact spirit reveal its heart's location is akin to asking it to offer up its life. 

"So? Where is this main city located?" Leon asked anyway.
