Dig Minecraft Deeper?

I play minecraft windows 10 version in a flat creative world and just want to build an ocean. However, it bothers me that you can only dig 4 blocks deep until you get gray - black blocks. After that there's nothing left… Just blue… How can I dig deeper than just 4 blocks until nothing comes?

You have to generate a new (flat) world with individual "Custom Settings" that is several blocks deep - you can also set other blocks as standard here:

This is what the menu looks like (you currently have Classic Flat):

A flatland world always has 1 grass 3 soil and one bedrock level. With Windows 10 Edition you can't go deeper.

You should be able to set how deep the world should be in the settings, but I think that is only possible if you create a new one.

Yes. But Mosquito doesn't play the Java version

But I can't find where in the settings

Then maybe there's another way to create another world. In any case, he / she can only try by creating a new world.

This is not possible in the Bedrock Edition.

What a thing?

You don't even know what you're playing? Ah yes

I'm really, really sorry, sir, but I've only been playing for a few days now, and you don't usually know that well!

Ah

So there's the Java Edition and the Bedrock Edition (Windows, Pocket,… Edition).

By the way, I'm 14, so I'm not sir

Lol me too
