Quick Transmigration: Your Mom Defies Fate to Teach You a Lesson

[Quick transmigration + no CP + not an indulgent power fantasy + entirely fictional] Note: This story has its own unique setup. Please don't read if that's not your thing. World One: An old-school modern romance. She transmigrates as the mother of a wealthy CEO, with a love-struck, ungrateful son. Is she just a tool for funding his romance? World Two: The 1970s. She transmigrates as a mother who favors boys over girls, with a wicked daughter who has her own System. Is she just a tool for earning quest experience? World Three: The apocalypse arrives. She transmigrates as a weak, helpless mother, with a son who's a lovesick fool and has overwhelmingly powerful abilities. Is she just a tool for handing over a pocket-dimension artifact? World Four: ... Shi Qi rolls up her sleeves. “You little brats, get ready for this big shot's arrival!” Shi Qi transmigrates into various small worlds as the protagonist's mother. She builds her career, gets revenge on the worst offenders, punishes evil and corruption, and saves the cannon-fodder characters doomed to tragic fates. The children in every world weep bitterly. “Mom, love me one more time...” New worlds are being updated...
