Fate's Little Feral Consort - Chapter 250 - Cousin Lu Jia

In a world where 70% of the population possesses powers managed by a LitRPG chip, Kang Ji-Hoon, a timid young man, joins the prestigious Apex Academy to save his sick mother. Ranked last at F with his seemingly useless ability to summon a dagger, he becomes the target of relentless bullying. Pushed to his limit, he unleashes the true power of his weapon, a dark and destructive force. As he transforms into a ruthless anti-hero, a cosmic threat emerges to assimilate humanity. Ji-Hoon then realizes his dark destiny: to save everyone, he must destroy everything.

Lady Bertia, who’s become my fiancée, is a bit odd. On our first meeting, she proclaimed herself a villainess noble girl who’s been reincarnated and said that she’s working hard every day to become a splendid flower of evil that’s elegantly put in her place.

I don’t get it.

But she entertains me because I don’t understand.

That’s why I think I’ll observe her for a while.

This is a story of a crown prince who’s so talented and handsome that he’s grown bored of his easy-mode life. A story of this prince observing a self-proclaimed villainess noble girl (who seems perfect at first but is a bit off) who’s become his fiancée as she snatches flags and breaks them into pieces.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
