One day...a monster suddenly appears from a cave that was buried a long time ago!
At the king's command, a team was formed to excavate the cave in order to investigate the cause.

Monsters spring up one after another. A world of darkness that continues forever.
If it's pitch black, turn on the lights, if the road is broken, build a bridge...If there's a hard rock, blow it up!
A great adventure begins in which you lead an adventure group and overcome many obstacles.

It's the mining members' turn in the morning! We will proceed with the construction and excavation of the cave.
And at night, it's the turn of the adventure group, which boasts the strength of the village!
The further you go, the deeper you go underground, the more treasure you may find.
Gather your treasures, powerful equipment, and unique companions, and go deeper!

As the popularity of the cave increases, groups of thieves may come to steal the treasure.
In that case, don't panic, set a trap and get rid of it.

You may be able to recruit the monsters you defeat.

Once you have secured the floor, merchants from neighboring countries will come to you with peace of mind.
You might be able to build a shop in a cave and make a lot of money.

This is a simulation game where you develop a cave and explore an underground world that has become a hot topic all over the world.
