I Left the Sect, Only to Discover a More Children, More Blessings System

I was an ordinary nobody in an immortal sect. When I got too old, they advised me to leave, so I walked away with just a little savings. But I had transmigrated, and I had a System. How could I accept that? I would defy fate and change my destiny. In this world of cultivation, I decided to follow the System's lead, have lots of children, and gain abilities and resources by leveling up through the System. I would rise from a nobody to the pinnacle, enjoy more children, more blessings in this cultivation world of Qi Refining, Foundation Establishment, Golden Core, Nascent Soul, and Spirit Transformation, and become invincible.
