Minecraft: Ender Dragons defeated, now what?

I've been playing Minecraft for 7 years with very good experience! I also know a lot about Redstone and stuff like that. But the question: I started a new survival world again and played through to the end! But what now? Is there any small event or what else can you do besides modernizing your own property?

Nothing really, because that was your goal in the game.

So you can't do more.

Maybe defeat the wither.

Wither and end forts for elytra

Just keep playing, explore the world, build blatant structures, everything.

Wither,

Full netherite,

Automatic farms,

Tall buildings

I already have, but thanks!
