I Can't Believe I'm the Demon King's Ultimate Weapon

Seeing their predicament, they seemed to be discussing something, but I didn't care. Looking back on the past few years since I came here, there were regrets, more or less, it ended before it even truly began. I glanced at the enemy so close, remained silent for a long time, then turned back, gazing deeply at the Demon King. Ilotia: "Master, do you want a new beginning?" The Demon King looked at Ilotia; it was the first time she had seen Ilotia with such an expression, something she had never witnessed before. Those clear, azure eyes, like unblemished gems, reminded her of her childhood self. Ilotia's gaze was filled with unwavering determination, captivating her completely. The Demon King: "Just as..."

The protagonist's story is a complete tragedy. She's manipulated from beginning to end, treated like a monkey by the Demon King and her best friend, a mere tool to be played with at will. The protagonist loses everything and finds no happiness in the end, instead being tortured and brainwashed by the Demon King before being killed alongside her. The Demon King never utters a single word of affection throughout the entire story; at most, she transforms from a tool to a pet, ultimately betraying the protagonist and causing her death. There's not a trace of love in her words. You can tell from the utter nonsense she spouts, and from my comments, you can see how disgusted I am by the Demon King and her best friend. This book is not suitable for everyone; proceed with caution!

A wise person judges by actions, not intentions. If someone is not inherently cruel but acts cruelly, then that person is cruel.

The character's psychological changes are actually quite easy to understand. Ilotia doesn't have as much control over her body as the Demon King; he even knows her deepest thoughts better than she knows herself. Ilotia's body is completely beyond her control, and coupled with her hidden masochistic tendencies, I think most normal people couldn't withstand the torture in that dark room. When the protagonist no longer resists the Demon King, their attitude towards him changes. This is mainly because the Demon King's combination of carrot and stick in the first half of the story created Stockholm syndrome. When torture becomes routine, the Demon King's gentleness makes the protagonist feel very fond of him. Now imagine...

Simply put, people who like this kind of thing are all sick; they lack free will and basic logic, they don't understand emotions, and they don't try to pursue their dreams. You are just people controlled by hormones; patients of this era also want to escape it.

This is disgusting. This is called "no thunder and no poison" and it even dares to label itself as invincible? A demon king who is so disgusting and cruel to the female lead, only occasionally showing a little concern—that's how true feelings develop. Even in the ending, the Demon King arbitrarily decided the heroine's life or death for his own purposes, but the heroine and the narrator both tried to whitewash the Demon King in various ways. It's so poisonous, I'm speechless. Any normal person would definitely seek revenge against the Demon King.

Compared to the mechanical nightingale, which is imprisoned in the king's golden cage and sings eternally until its clockwork decays. I'd still rather see a story about a viper secretly winding up a clockwork mechanism so that a nightingale can peck out the king's eyes. What exactly does the mechanical bird want to do? Until its clockwork power runs out, whatever it does is merely carrying out someone else's orders.

A group of people were tearing each other apart over the plot of the book, eventually escalating to personal attacks. The argument is that there's no inherent superiority of "feel-good" or "angst" novels; it's just a matter of different tastes since everyone's reading web novels. The problem lies in the discrepancy between the book's marketing and its actual content, or rather, the lack of clarity. Adding a "depressing" tag or a dark and brutal warning in the synopsis would have avoided this mess. With its "isekai" and "invincible" themes, everyone's looking for a "feel-good" story, but what they got was a depressing, forced, and abusive relationship, starting with torture, manipulation, brainwashing, and mental control. The key point is, if the protagonist could have turned the tables and achieved a comeback, I'd admire their resilience, but unfortunately, that didn't happen; if the two found true love that transcended master and servant, I'd...

This novel perfectly hits my fantasy. I've always fantasized about a novel where the female lead is invincible but is trained and served wholeheartedly. After so many years, I've finally found one. After reading the comments, I finally understand why there are so few novels like this.

Every time I browse the "Invincible" tag, I see this book. Well, I won't discuss whether using the "Invincible" tag is right or wrong—after all, a bunch of pseudo-Invincible authors use it too—but I don't know how they dared to write something without any plot holes or harmful content. Do they think they can write anything without plot holes or harmful content? Then all the books that were previously criticized for having plot holes or harmful content can be written like this, as long as the author doesn't admit it. You've really gone to a lot of trouble to find readers who like your work; it's not easy to find them.
