After the ‘100-Year War’ between the Necromancers and Priests, an all-time genius who’ll shake the power structure was born. “Am I a rare case or something? Do I have talent?” A potential beyond all imagination. He obtained his father’s undead army and entered the great Necromancer school of Kizen that divided the continent. Geniuses are geniuses, even when gathered among the elites. The research community was flipped on its head by the appearance of a new case. Professors wouldn’t leave him be alone, wanting to make him study directly under them. Officials from all over the kingdom and heads of organizations fidgeted over whether to scout him. “Professor! When can I make a Lich?” “Gimme a break. How talented are you? You’re crossing the line, honestly.” A genius among geniuses had appeared.

Gu Yanfei was reborn.

In her last life, only after her death did she find out that she was a real daughter in a book of true and false daughters.

The original female protagonist, Fake Daughter, is the daughter of luck. She occupies a magpie’s nest and is loved by thousands of people. She is the eyeball and heart of the Gu family, stepping on her Gu Yanfei’s flesh and blood for a lifetime of honor.

In that lifetime, Gu Yanfei lived and died unclearly.

After her death, she was reincarnated into the realm of self-cultivation and became a medical practitioner. She didn’t want to, but after practicing for two hundred years, she was struck by a thunderbolt back to her previous life.

Back to the time when the true and false daughter’s life experience was revealed.

When the real daughter came back, everyone in the Hou residence laughed at her with no ink on her chest and a straw bag.

But I don’t know that Gu Yanfei is now a full-level rebirth!
