one way know to go outside is underwater river

when sail down the river until vilage reach off eye view

river will wider and water more deeper

while cannot see under water river anymore look at front

will see destination here

but when come from outside mustknow village is true not a tale

while sailing at all of water in eye distance

will smell Minsta Flower even on sunlight

follow smell

not too long

will see underwater river

and reach village at next moring

sometime lost ship goto village

with empty supplies

villager will give some supplies and destination

while ship go outside

at sometime will comeback to thank for help

with any excite story , funny item for villager that not go outside
