some ideas for discovering ancient city's location

I thought it was very interesting when archaeological functions were announced in the past.

But that function was not added in the end.

So I thought a lot about archaeology to have a more useful function.

I heard that the ancient city, which is scheduled to be updated this time, has a very low rate of creation in the world.

So just as you can find out the location of a forest mansion or a ocean monument through a transaction with villagers, it would be really novel if you could find out the location of the ancient city that will be added this time using archaeology.

For example, discovering maps of ancient cities buried in the ground. Since ancient cities have not been officially added yet, I don't know if this will help, but I think it will be an interesting system if added.
