According to the rules of the Heaven-Tier Sea Zone, no battles are allowed in the World Tree Sea Zone, and fleets are prohibited from firing during the competition for the Sea God Fruit.

Inside the World Tree, there are numerous independent spaces where only the strong can compete for the Sea God Fruit.

The people of the Heaven-Tier Sea Zone seem particularly concerned about the World Tree. Even though Delia was fuming with anger, when she reached this sea zone, she forcibly suppressed her rage.

"Alright, kid, see you at the World Tree!" With that, Delia led her people back to their battleship.
