Cadric and zinnia interaction

So here is my hypothetical board state I have cadric soul kindler -legendary permanent etb copy it and zinnia valley's voice- offspring(copy on etb if cost payed as cast)

I play any legendary doesn't matter what happens? I think that there are 2 possibilities 1 I get a total of 3 creatures the original one from cadric and one from offspring 2 I get 4 because cadrics copy also creates an offspring
