Search for a Webnovel/litrpg

So I’m looking for a Webnovel/cultivztion/litrpg story I can’t remember the name of. World building is vast, swallowed star / primal hunter vast

Mc is a kid on a backwater planet in the human domain. Basically there is an IA that governs the human domain that classifies its citizens into classes

Our mc manages to earn contribution towards better citizen class by inventing a new cultivation method. His progression is kinda similar to swallowed star or desolate era

There are different races, one insect race and others. Eventually to reach the highest power level in his universe he has to extricate himself from the river of time

He leaves his home universe if I recall

All I can remember !
