When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted.

Not only that, the Gu in his body could cultivate on their own.

[Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!]

[Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!]

[Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!]

[Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!]

[Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!]

“Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.

Victoria Garcia signed a slave contract, but accidentally fainted in bed!“Arnold Johnson, you are a monster! You said you could wait three years!” She complained!“I would be less than one if I didn't take an opportunity after it presents itself!”Then, on a certain night...“You're a scoundrel and a scumbag!” Xiu Xiangwan yelled on the verge of falling apart.“I could be worse if you dare to test me!”“...”Arnold Johnson is the second child of the Johnson family, one of the six top families of business magnates and owners of Johnson Holdings. Everyone says that he was affably evil and elegantly ruthless, and he was said to have seized an opening to engineer his own brother's death, hence inheriting Johnson Holdings!Victoria Garcia was the daughter of a family who now fell to dire straits, pawning herself off to Arnold Johnson to keep her mother out of prison...

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.
