One Piece: Madness of Regret - Chapter 15: He was me(1)

I was a failed experiment

Corporate slave Alexander dies with only one regret—not finishing the fantasy novel in his hands. Fate has a twisted sense of humor when he awakens as Alexander Flamingo, the perverted villain destined to be expelled and killed in that very story!Armed with complete knowledge of the original plot and a mischievous “Harem King System,” Alexander plans to rewrite his fate. No longer the one-dimensional pervert of the novel, he'll use his future knowledge to manipulate heroes, seduce heroines, and rise from disposable villain to the true mastermind of this world.The system grants him power through every relationship he builds—but can this calculating reincarnator use his second chance to avoid his predetermined death and become the ultimate Harem King? One thing's certain: this story won't follow the original script.

As long as you are brave enough, Insect Girl will take maternity leave (King of the Undead)

Can the ghost of the Demon Slayer be able to conceive a child? Let the miserable girl verify it.

Infinite comprehensive flow, harem flow, I wrote the book for the cute girl in the second dimension.

The heroine is a must! A female partner is also necessary! No… it’s nothing! Just basic operations.

The first world “School Island” “Saga Idol is Legend”

The Second World “Demon Slayer”

The third “King of the Undead” and “The Rising of the Shield Hero”

Fourth “Goblin Slayer”

If you have a favorite girl, please say in the book review, if you miss a girl, please point out.

Please don’t tell me not to dismantle cp and the like.
