Synopsis

At the start, I became a rich second-generation heir with a beautiful wife and a stunning school belle for a sister-in-law.
But Xu Mu couldn’t bring himself to rejoice.
The reason? He had transmigrated into the brainless villain of a novel—one who ab*sed his wife, forced the Dragon King’s sister to live in a doghouse, and ended up having his ashes scattered upon the Dragon King’s return.
Fortunately, Xu Mu awakened the “Justice System,” and he was determined to rewrite his doomed fate.
A wife should be cherished, and of course, his sister-in-law deserved to sleep in the villa’s cozy bed.
When the Dragon King finally returned, he was greeted by a loving and harmonious family.
Xu Mu soon realized that aside from the Dragon King, countless other protagonists began emerging—all targeting him—forcing him to fight back.
You have a few breathtakingly beautiful senior sisters?
Sorry, but they’re my senior sisters now.
You’re a retired soldier king searching for your first love?
Too bad—your “white moonlight” already sees me as hers.
…

Xu Mu faces off against multiple “Original Protagonists” who embody classic Chinese web novel tropes.

The Protagonist Type	The Trope	Xu Mu’s Strategy
The Dragon King	God-like soldier returning to find his sister abused.	Treats the sister like royalty; turns the “enemy” into a “brother-in-law.”
The Soldier King	Retired mercenary looking for his “White Moonlight” (first love).	Becomes the White Moonlight’s savior before the Soldier King even arrives.
The Sect Prodigy	Arrogant youth with multiple “Senior Sisters.”	Steals the loyalty (and hearts) of the Senior Sisters through genuine kindness.
The Reborn Master	Someone who lived a past life and wants revenge.	Uses system knowledge to stay three steps ahead of their “future” plans.

📂 Interface Système : The Status Window (Xu Mu)

Attribute	Classification	Description
Class	Wealthy Villain / Justice Seeker	A “Rich Second Generation” heir fixing his reputation one good deed at a time.
System	The Justice System	Rewards him for acting “upright,” which ironically makes him the most “villainous” threat to the original heroes.
Disposition	Level-Headed / Selective	Unlike most “Crash-out” cultivation MCs, he uses logic and avoids unnecessary murder.
The “Glitch”	Protagonist Bromance	Uniquely, he actually befriends one of the heroes who was “programmed” to hate him.

Editor's Note

💡 The "Fast Food" Gem. This novel is the definition of high-quality "fast food" literature. It’s addictive, follows a predictable loop, but is seasoned better than its competitors. It avoids the "Psychopath MC" trap—Xu Mu has genuine empathy and a great relationship with his father and wife, which grounds the story in actual emotion rather than just "face-slapping."

The Harem Dynamic. This is a slow-burn harem. For the first 100+ chapters, the MC is genuinely devoted to his wife. When other women are added, they usually have distinct personalities (like the tsundere Demon Queen) rather than being "carbon copies" of each other.

"The original author wanted me to be a brainless villain who dies in a ditch. I decided to be the guy who buys the ditch, turns it into a villa, and invites the hero's sisters over for tea."

*842+ chapters of villainous redemption, protagonist hunting, and a Dragon King who really needs to learn to call his sister more often. Ongoing — and still the best brother-in-law in cultivation.*

Experience Curve

Ch. 1–150 (The Domestic Fix): ⭐⭐⭐⭐⭐ – The most unique part of the book. Fixing his marriage and the "Doghouse" situation is satisfying and funny.

Ch. 151–400 (The Hero Hunter): ⭐⭐⭐⭐ – The world expands. Multiple protagonists appear simultaneously. The "Misunderstanding" comedy hits its peak.

Ch. 401–644+ (The Urban Immortal): ⭐⭐⭐ – Traditional urban cultivation kicks in. The stakes get higher (Gods, Demon Queens), but some readers find the pace slowing down.

WebNovelDB Review

8 /10

One of the best "Villain vs. Harem Protagonists" stories. It’s lighthearted, consistent, and avoids the worst xenophobic/psychotic tropes of the genre.

Writing & Pacing: 7.5/10. Solid and consistent updates. It can feel "passive" because the MC often waits for the next "hero" to show up before acting.

Character Development: 8/10. Surprising depth for the side characters. The heroines feel like people with their own goals rather than just "trophies."

Logic & Reason: 9/10 (For its genre). The MC actually uses his brain. He doesn't kill everyone he sees; he negotiates, manipulates, and makes allies.

Satisfactory Factor: 8.5/10. Watching "Arrogant Protagonists" lose their plot armor to a guy who is just being a decent person is pure catharsis.

The Archetype: The "Reformed Villain & Protagonist Hunter." You want a story that plays with the "Urban Cultivation" genre’s most tired clichés. Xu Mu transmigrates into a rich, abusive villain destined to be killed by the "Dragon King" (a classic protagonist trope). Instead of doubling down on evil, he uses his "Justice System" to treat people properly—starting by rescuing the Dragon King's sister from a doghouse. This is for readers who enjoy Urban Fantasy, System-assisted growth, and the "Villain vs. Many Protagonists" dynamic.

Not For You If: You hate Harem novels or "Simp-lite" MCs. While the MC starts off faithful to his wife, the cast of beautiful heroines inevitably grows. If you find it frustrating when an MC is "too soft" toward female characters who previously tried to kill him, or if you prefer a protagonist who actively hunts enemies rather than reacting to them, this might feel too slow for you.

Harem Note: This is a slow-burn harem. The MC is genuinely devoted to his wife for a long time. If you're looking for instant romance with multiple girls, you'll be waiting. If you want a harem where the women actually have personalities, you're home.
