Turns Out, I’m from a Real Aristocratic Family! - Chapter 212 - : Reversal

What got summoned was the world’s strongest sociopath.

Years ago, Earth was indoctrinated into the “System.”Earth was not the only place with the System, however. With the System came the other races, Invaders. The Invaders had one goal, to obtain ownership of this new habitable planet. This created a bloodbath, and for years the war raged.This didn't really have much to do with Derek. Derek was kind of a loner. Yeah, he enjoyed the occasional chat or drink with others, but he never stayed in one place too long or really got to know anybody new.Derek did happen to be rather strong. After the years of fighting monster and Invaders alone, he had become quite adept at surviving. One thing that helped keep him alive was his refusal to get involved with others. He rarely cooperated with teams.One day, Derek broke his rules and decided to lend some help, as the mission didn't seem too hard. He should have stuck to being alone.

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!
