[Rebirth + pocket dimension + revenge + adorable baby + cute pets] Nine months pregnant, her younger sister and her fiancé, the Crown Prince, conspire to frame her father for treason. Her entire family, along with her maternal grandmother's family, is wiped out.
Her sister and fiancé then cut open her nine-month-pregnant belly. Her baby, not yet able to open its eyes or see the world, is brutally killed.
She was once a princess of the Immortal Realm, traveling among the Immortal, Human, and Demon realms in hopes of bringing them into harmony. When she tried to break through to the Heavenly Realm, so-called righteous people slandered her, causing her cultivation to backfire and her divine soul to scatter.
He is the Demon King. He has always scorned the Immortal princess's foolish belief that the three realms could live in harmony, yet he is deeply moved by her kindness and courage. When he learns she has been murdered, he willingly gives up his cultivation so she can enter the cycle of reincarnation.
He follows her through every lifetime, but only regains his memories after she dies.
Reborn one day with the memories of her past life, she returns. The scheming younger sister who transmigrated into a book is so fond of the Crown Prince? Fine. The two of you can get together early and weather your troubles side by side.
You still want to keep your seat as Crown Prince? Dream on. Go live as an ordinary commoner!
Not one of those responsible, directly or indirectly, will get away!
In this life, he returns with all his memories. He won't spare a single person who has ever bullied her!
