That logic is flawed imo, because he attributed the invincibility to the supernatural weapons, that obviously have been around a while. Black zetsu has seen all of shinobi in history including sage of six paths, so him calling invincible is a feat. And the invincibility doesn't just come from the zetsu it comes from the writer too, amazes me people continue to disregard this.
