The arrival of the Goddess of Riches priest made Soran slightly cautious.
As his strength grew more and more, it would inevitably attract the attention of many old and powerful forces. Fortunately, it was the priest of the Goddess of Riches. If the Storm temple secretly sent someone to contact him, it would be even more troublesome.
Soran's island was very close to the Amazons, thus rejecting them would mean hostility.
If Soran was able to ignore the Sea temple then he would have the power to do what he wanted.
He must enter the realm of legends!
Soran felt that he must quickly become more powerful. If there were three figures around the realm of legend, then no temple would try anything on them.
After settling the priest, Soran then brought some men to deal with the Quetzalcoatlus.
