In this article, I'll tell you about a very interesting seed called Chickinzzz which is a fairly large island that has all the resources for a long survival. The main resources you can find and get it will be diamonds and iron, for this you will need to descend into the cave, the road to which you will find in the pictures below. Your spawn will happen almost in the centre of the island, then you need to go down to the sea and there you will find a cave that will be fraught with gold, diamonds, coal and iron. Also on if you find on the beach gravel and start digging down, you get into the extensive network of caves that run through the entire island and they have huge deposits of various resources that will be useful in the process of survival.
