Based on Gu Jun's understanding of rituals, he knew that every ritual had an anchor. It was the equivalent of a creature's heart, examples including the patients' consciousness in the House of Worm, and the transmission tower inside the desert loop. The eye of the storm that he saw was clearly the heart of this dimensional ritual. Every other spell casted on the battlefield originated from this one spot.
"As long as we can disturb this eye of the storm, we might be able to interrupt the ritual. Even if it's only for a few seconds, that's more than enough for the cannonballs to sink those ghost ships!" Gu Jun explained, "Once the ships are destroyed, we should be safe."
