ruined underground villages

ruined underground villages would be abandon villages. The house where made of more stone and or deepslate. In chest you can find raw iron, raw gold, raw copper, cole, cobblestone and deepslate. I also like the idea that you could find lots of rotten flesh and bones like the flesh of the farm animals are rotten. There would be alot of cobwebs just like in the zombie villager villages. The houses could also be collapsed, fallen, burried by rocks.

This would really give you the feel you are underground and that living under ground is not an easy option. It would add alot to the experience.
