My Mech System Trades Universes

I've died twice: first as a legendary General, then as a betrayed game BOSS. Now, I'm reborn as the world's most pathetic 'cannon fodder' – broke, weak, and saddled with two mysterious, unhatched 'egg babies' that require a fortune in special nutrients to survive. Starving and desperate, a familiar glint on my wrist reveals my secret weapon: my former life's combat 'Teaching System' has transmigrated with me! This isn't just about reclaiming my formidable power; it's a universe-spanning trading platform for anything from advanced mech tech to forbidden cultivation methods. But with vengeful reborns and scheming Mary Sues after me, and a vast, dangerous interstellar society to navigate, can this disgraced War Goddess secure her children's future and finally rewrite her fate, or will her past lives catch up to deliver the ultimate, crushing defeat?"
