Well, for the five-digit crystals, Ji Chen felt that it was worth investing some effort into the investigation. This could be considered an exchange of interests with Miligas.
After all, Miligas must have had a reason to present these supposedly elven spirit crystals to him as a reward.
As for how long it would take to gather intelligence, he couldn't just wait around. During this time, Ji Chen decided to visit the Irante Temple that Miligas mentioned.
He had a significant interest in this temple established by the gods of the Orderly Divine Lineage.
The power of the ocean within him was indirectly bestowed by a god from the Orderly Divine Lineage. Perhaps he could learn more about this power within the Irante Temple.
On the third day of his arrival in Maple City, Ji Chen led his heroes and army of the Crown of the Ocean to the border of the Maple Principality.
