From the moment he had received the passive ability [Language comprehension], Dilan had been thinking about something particular.
'Not only are both the Ligrav and Rasnian race experienced in absorbing Essences, but they can hand out a Tier-1 passive ability like [Language comprehension] to someone they never saw…. Their knowledge about the system, and how to procure ability crystals should be far higher than mine!'
That was why Dilan thought about making a deal, without actively showing that he didn't know how to procure Ability crystals other than by trading them with Gates, and random fortune encounters.
"How about I and my group provide the Sun temple with sacrifices, and you provide ability crystals, treasures, and other things in return?"
Of course, Dilan didn't know if the Sun temple usually accepted any kind of corpse as a sacrifice. He was taking a big gamble by demanding ability crystals and treasures in return for some corpses.
