First loop: Yuan Yizhen was never born.
Second loop: Yuan Yizhen was born, disguised herself as a man, unified the north and south, and brought four hundred years of chaos to an end.
Third loop: A transmigrator tries to kill Yuan Yizhen and take her place.
Fourth loop: A reborn person and a transmigrator show up.
Fifth loop: A whole wave of reborn people and transmigrators arrive.
Sixth loop: Yuan Yizhen: I'm so tired of this.
P.S. The heroine has been made to change her method of unifying the realm five times because of reborn people and transmigrators. This thoroughly proves that transmigrating and being reborn don't make you smarter: your dad is still your dad. But it's also pretty tragic. She's unified the realm five times, and thank goodness she doesn't remember, or she'd be spitting blood.
The author will only go into detail about her sixth-loop approach. If I wrote all five loops, I'd be signing my own death warrant.
The heroine has great personal charm. When it comes to women, she's the type to treat them all with equal warmth, and has many admirers (mostly women. The heroine disguises herself as a man early on, and young ladies who meet her fall for her for life. Even after they learn the truth later, it's still hard for them to climb out of that hole.)
