Extra's Strongest Bloodline

This book is not a masterpiece, it is just a cliched isekai novel with no innovation. Moreover, for those of you who like main characters who stand above all, cruel and heartless, cunning and manipulative, perfect and never make mistakes, invincible and untouchable; then this story is not for you. - Writing Style? Honestly, my writing style is simple. - Main Character? He's not a hero. But still principled, like keeping his promise. I plan to make him have a hobby of collecting exotic animals in the future. - MC Power? Wish-granting system and Extract. Fighting style is ninja-like, focusing on speed, stealth, and careful strategy. - Romance and Harem? Maybe yes and no. Honestly, I'll be flexible and follow your wishes as a reader. - Details? Remember that this is a Webnovel. It is not released in full directly, but is updated from time to time. Even if there are plot holes, they will be patched up in future chapters. - The World? Western fantasy with a bit of Sci-fi flavor. For those of you who like mythology and legends, such as the gods of Olimpus or Asgard, you might like it. - Other Characters? Maybe I'm being a bit arrogant, but I invested a lot of time in thinking about the powers they have, thus making them unique. But you're the one who judges whether it's cliché or unique, so please read on. I hope you like my book and leave a positive review. I really hope this book gets a lot of positive reviews, so please. Thank you for reading my book.
