Plant only aquatic spiritual medicine?
They definitely need to plant aquatic spiritual medicine, but they also need to plant other spiritual medicines. For example, that millennium vermilion fruit tree branch in his hand definitely needs to be planted.

A treasure like the Sea-Suppressing Pearl can't be easily disclosed, so they can't invite other Array Masters to set up the formation and can only do it themselves.
