The Possible Value of the Map 

"That I don't know. But the people I know who know about it think that the group that finds the map and reaches the Seraph Ancient Sarcophagus will be able to achieve many grade-4 resources. But not only that, they will be able to recover that man's corpse."

Minos frowned as he heard this comment from her, not understanding why that man's corpse would be of any significant value.

He knew about the properties of a Spiritual Demigod's body, as should be the case with this person. For himself, that body could serve as a nutrient for one of the spiritual roots in the northern region, something that could help him increase the energy density in that area of the empire.

But that shouldn't be so valuable for high-level people from the Eastern Empire and the Blood Triangle Pirates. 

Not to mention that from time to time, high-level people would die in those forces, and they would have corpses of a similar level.
