Help me find the novel

Edit: Martial Peak is the novel. Thank you

Hi all,

I've forgot about a novel title. Don't remember the MC name too. I only know few details from middle to later chapters of novel.

Cultivation system has a level where they create inner worlds where humans can live. MC can project his own clone to interact.

Multiple cosmos/universes/realms are there. If any new realm opens up, they go and mine resources.

MC was kidnapped I think by a sect to be labor, where a rooster like bird initially bothers him but becomes friend. Bird also has mysterious background. That sect is actually on a giant turtle I think.

The people with last level in cultivation are rare and later mc finds that they are sent to a battlefield that's actually a club of realms taken over by a evil entity with its spawns.

MC goes into a space in a painting also, there's also a weaponsmith who is legendary but helps mc.

The evil entity was a child accompanying the 10(probably) highest cultivators from an Era long back.

MC defeats evil entity and takes the child(memory gone evil entity) as a sister at end.

In middle chapters there's even some ice sect, dragon sect, a dragon egg hatched and calls MC as dad etc.

Not I Shall Seal the heavens and A will Eternal.

I also remember that mc visits a dragon clan where he helps hatch an egg and the child calls him dad even though his birth parents are alive.
