Summary

... Read More

Su Yuan is a time traveler who crossed into a world called Blue Star, where cultivation civilization has reached a high level of development. Orphaned and poor, he relies on doing homework for others and part-time jobs to support himself. He is admitted to a key immortal cultivation high school, but his grades are only average. Over two hundred days before the college entrance examination, he finally receives a system, but it is the “Bring Chaos to the World” system, which assigns him Demon Lord tasks. The first task is to seize someone else's opportunity ten times. Su Yuan discovers that even stealing a box of dragon fruit from his roommate Chu Lanxi qualifies as seizing an opportunity in this era. He decides to work as a delivery rider for a crowdsourcing platform and deliberately loses meals to complete the task. System rewards include the Fanjing Demon Heart. During his delivery work, he notices that the security guard Uncle Wang in his residential community is extremely skilled at intercepting delivery workers. The system recognizes Uncle Wang as a Demon Path Senior who has suppressed a region for thirteen years, blocking countless Righteous Path prodigies. A new task is triggered: take a demon as a master and learn his method of obstructing the righteous path. Su Yuan decides to become a security guard to learn from Uncle Wang. He studies the Eighteen Styles of the Divine Fork and, through the system's random reward, upgrades the technique to the perfect stage. Next, a task appears to control a region: gradually erode Uncle Wang's position, seize his power, and establish Su Yuan's own image as the master of this demonic realm. The task requires accumulating reputation points by stopping delivery workers from entering the community. Su Yuan continues his security guard work, and his first interception successfully repels a delivery worker. The story follows Su Yuan's journey of balancing system tasks, his part-time jobs, and his interactions with Chu Lanxi, who remains a sharp-tongued but supportive friend. While the system pushes him toward the path of a demon lord, Su Yuan's everyday struggles and humorous situations define his growth.

I must admit, I was initially spooked by the familiar premise, but having experienced similar narratives frequently enough, I've come to understand that many Chinese authors often draw inspiration from one another. The novel 'I Cultivate Legally, Why Call Me a Demon?' kicks off in a manner that immediately recalls the delightful misadventures found in 'No Money to Cultivate Immortality?'. However, I wouldn’t classify this resemblance as a drawback, for both novels represent the pinnacle of what the sci-fi xianxia genre has to offer. While 'No Money to Cultivate Immortality?' leans towards a more brutal and realistic portrayal of its themes, 'I Cultivate Legally, Why Call Me a Demon?' embraces a full comedic approach, masterfully depicting a modern and peaceful society catapulted into chaos by the antics of an unwilling inheritor of a demonic legacy. The humor is genuinely refreshing, featuring outlandishly funny moments, such as the “Security Guard Sacred Body" and utilizing corpse control techniques for the absurd purpose of roasting food. I must say, it has been a long time since I've found myself laughing heartily while reading web novels, and this one has certainly delivered on that front. In essence, this novel is a classic system narrative. Typically, this would set off my caution flags, given how many system novels often suffer from narrative stagnation. However, in this story, the system is not just a plot device—it feels like a character in its own right. Throughout the narrative, it continuously attempts to hype up the main character's (MC) demonic talents, yet the MC seems to navigate the challenge of legitimizing such demonic techniques in a modern context with surprising ease. This delicate balance is the crux of this novel: while the system is undeniably powerful and overpowered (OP), the MC still must engage his intellect to apply these abilities judiciously and manage the repercussions on his reputation when he clearly employs demonic arts. Notably, the pacing of character progression aligns beautifully with the narrative structure. It took about 200 chapters for the MC to reach a level of strength that feels genuinely significant, especially considering how far he had to go since the beginning. In contrast to many other system novels where characters blast through power ceilings without a second thought, this author has successfully crafted a pace that allows for growth and development while maintaining the tension and stakes. Even as the MC becomes more powerful, he retains evident flaws and weaknesses, ensuring that he must rely on both brawn and brain during confrontations, lest he finds himself in dire straits. The supporting cast is another highlight of the narrative. The characters introduced early on remain relevant even after 200 chapters, thriving alongside the MC's journey. The gradual, step-by-step progression the MC experiences serves to enhance the significance of each side character, fostering a sense of longevity that is often missing in similar works. Furthermore, what sets this novel apart from 'I Cultivate Legally, Why Call Me a Demon?' is the promising trajectory of these characters. They will continue to play increasingly pivotal roles as the story unfolds, adding layers of intrigue and excitement to an already rich tapestry of storytelling. In conclusion, 'I Cultivate Legally, Why Call Me a Demon?' is an exquisite blend of humor, clever storytelling, and character depth, making it a standout read in the sci-fi xianxia genre. For those looking for a compelling tale that intertwines the absurdity of modernity with traditional elements of cultivation, this novel is not to be missed.

This story has certainly provided me with some delightful moments of laughter so far. The development of the main character, while following the familiar trope of becoming overpowered, is not the primary focus of the narrative. Instead, the real charm lies in the protagonist's self-perception as a perfectly reasonable and normal student, juxtaposed against the increasingly alarmed and often exaggerated reactions of his classmates and others around him, who view him as increasingly sinister and evil. What I truly appreciate is the absence of a harem or unnecessary romantic entanglements, allowing the plot to stay focused on humor and character development without veering off into cliché territory. Moreover, the book is filled with vividly described scenes that are rich with comedic gags, providing a wonderfully entertaining experience. I can't help but think that the original language might contain even more nuanced humor and cultural references that I'm missing out on due to my limited understanding. This aspect adds an intriguing layer to the reading experience, as it inspires curiosity about the original context and how it might enhance the overall enjoyment of the story. Overall, I eagerly anticipate what laughs and surprises are yet to come in this delightful read!

The moment Su Yuan says “damn system, either don’t come, what’s the point of giving me a demonic cultivator system” summarizes the whole vibe. He expected golden fingers and got a trolling system. The self-aware protagonist is a trope, but it’s executed well here. He doesn’t fall into despair or suddenly become evil; he adapts and finds a way to exploit the system’s definitions. That cleverness is what makes reading fun. I’ll keep following his journey to see how long he can keep this up without actually becoming a villain.

Overall, this is a solid slice-of-life cultivation comedy with a fresh modern setting. The system is not an instant-win button but a source of absurd side quests. The protagonist is relatable and funny, the supporting cast is lively, and the worldbuilding is rich with small details. It’s not trying to be deep or epic, but it’s genuinely entertaining. Perfect for winding down after a long day. I’d recommend it to anyone who likes light-hearted cultivation stories with a modern twist.

I really want to see Chu Lanxi’s reaction when she finds out Su Yuan has become a security guard on top of being a delivery driver. The contrast between his new uniforms and his usual school life should be hilarious. Also, what will she say when she discovers he’s been stealing other people’s takeout? She’ll definitely tease him about his “demon lord career”. Their interactions in future chapters are definitely what I’m most looking forward to. Please give them more scenes together!

The biggest weakness so far is the lack of a clear overarching plot. Each chapter reacts to the immediate system task, but there’s no obvious antagonist or mystery besides the system origin. It’s fine for a comedy, but I hope the story eventually focuses on something bigger, like the college entrance exam or the true nature of the system. As long as it maintains the humor and charm, I’ll keep reading. The characters are too fun to drop.
