The yard is used in the early stage. Later, you can explore the forest to get wood, the mines to get stones, and then there is a chance of alchemy (the above is the experience of the PC version, I haven’t tried it on the mobile game yet)

Go explore the mountains and forests, there are many oracles.

There is no shortage of various types of wood and mountains to explore. Ancient and cursed stones. I really can’t find where to get them. I just randomly found them through alchemy.
