Alright, the hostage exchange is complete, everyone has developed a foundation of trust for cooperation, so next is how to take action. According to Gu Fan's plan, we wait for the island to resurface from the sea tonight when the fog comes, and investigate what's there.
Before, many sea serpents prevented them, forcing Gu Fan and his team to escape. Now, the sea serpents have been mostly eaten by the sea eagles, so that threat is no longer a concern.
The most troublesome issue, however, is the Stone Array. The giant stones form a huge maze that seems to move, and coupled with the fog, everyone just goes around in circles, delaying time.
A maze covered by fog is indeed tricky. Without a proper plan, everyone would probably be stuck repeating the process of landing on the island. Gu Fan doesn't want to waste this time, as the island could drift somewhere unknown next time.
