After Successfully Saving the Male Leads, I Switched to Strategizing Them

She, Liu Nian, has lived for thousands of years, completing one task after another, transmigrating into various books. This time, the book she transmigrated into gives her the most headaches.

In her previous transmigration experiences, she encountered all sorts of handsome men and beautiful women, but this time, she's actually tasked with raising a child.

Liu Nian doesn't know how the plot of this book will unfold. The 'broken' system that partnered with her told her, on the very first day she transmigrated a hundred years in advance, where the male leads would be born in the future, and then showed her their mothers. After that, it successfully crashed and hasn't shown any signs of life since. Liu Nian suspects it has likely been purged by the main system, otherwise, why hasn't it rebooted after a hundred years!

Liu Nian only knows that this book has three male leads. She's not sure if there’s a female lead. Anyway, her mission is to raise the male leads and prevent them from developing anti-human tendencies, raising them to adulthood safely, and then her mission will be complete. However...

Can someone tell her! Why does she have to be the one to strategize for the children she raised herself!
