While at the Evil God's Burial Ground, to the summoned human superpower users, Iron Arm, Mia and other Bansel people were NPCs.
However, for Iron Arm and the others, the Evil God Resurrection Ceremony was a cataclysmic crisis for their tribe.
Now it was the Bansel Clan's turn to be summoned, and to the people of Fusang City, the humans indeed were NPCs, although they did not understand the meaning of NPC.
Lu Heng and his two companions were not summoned, so they would not receive the divine energy reward for completing the mission, but they had the opportunity to obtain extra rewards.
For example, when at Stone Hammer Castle, by burning off Evil God Barton's finger, they had obtained a sum of divine energy.
Therefore, this Abyss Battlefield still held value to be explored further.
To obtain these extra resources, one needed to target the core objectives of this Abyss Battlefield, which were the Soul Capturing Monster and its controller behind the scenes.
