Invincible! This person has lived for a billion years – Complete Guide & Review

The Story in 3 Sentences

A twenty-year-old man named William Johnson lives in a poverty-stricken district, his true nature hidden from the world despite having lived for an astonishing one billion years and shaped human history from the shadows .

His quiet existence is shattered when five of the world’s wealthiest tycoons simultaneously descend upon his slum, revealing that fragments of his ancient wisdom have already elevated them to global dominance .

As William reluctantly re-engages with the modern world, he must navigate new relationships, confront reincarnated rivals from eons past, and decide whether to remain hidden or finally embrace his role as an eternal, invincible force .

Why It Stands Out

1. The Billion-Year Echo in a Twenty-Year-Old Frame

Unlike typical overpowered protagonists who gain strength through sudden transmigration or system-based cultivation, William Johnson’s power is the accumulated weight of lived time itself. He isn’t just strong—he’s foundational. Religions bear his fingerprints, empires rose at his whisper, and cosmic events unfolded under his indifferent gaze. His struggle isn’t to become invincible but to pretend he isn’t, making every mundane interaction laced with cosmic irony .

2. Comedy Born of Cosmic Detachment

The novel mines humor not from slapstick but from the absurd gap between William’s eternal perspective and the fleeting anxieties of mortals. When a business tycoon begs for investment advice, William casually references market trends from the Bronze Age. When a young rival boasts of his “peerless” cultivation, William recalls mentoring his ancestor. This tonal contrast—between slice-of-life banality and billion-year gravitas—creates a unique comedic rhythm rarely seen in the genre .

3. Harem as Historical Reckoning

Rather than a shallow romantic subplot, the harem structure serves as a narrative device to explore William’s fractured legacy. Each woman he encounters carries echoes of past lives, forgotten promises, or unresolved betrayals from epochs long buried. Their attraction isn’t just to his power but to the ghost of who he was—and who they once were beside him. This transforms the harem from fan service into a haunting chorus of memory .

Characters That Leave a Mark

There’s Maria – a sharp-witted woman who rarely wears makeup and shares quiet dinners with William at The Silver Fork restaurant in New York City, her grounded presence offering a rare anchor to his drifting eternity .

You’ll meet Chu Lingxiao, who regards reincarnated immortals with icy contempt and can erase a so-called “Sword Immortal” with a mere wave of his hand, embodying the ruthless judgment of those who remember the old cosmic order .

The Flaws Fans Debate

Some readers criticize the repetitive structure of early chapters, where powerful figures repeatedly seek William’s guidance only to be humbled by his offhand remarks, creating a formulaic rhythm that slows narrative momentum.

The harem elements, while thematically justified, occasionally veer into trope-heavy territory, with female characters sometimes defined more by their devotion to William than by independent arcs.

A segment of the audience finds the protagonist’s near-absolute power limiting dramatic tension, as conflicts are often resolved through revelation rather than struggle, reducing stakes in key confrontations.

Must-Experience Arcs

Ch. 1–20: Awakening, A New Beginning – The story opens with five tycoons invading a slum to kneel before William, unraveling the mystery of his hidden identity while establishing his billion-year backstory through subtle flashbacks and cryptic dialogue .

Ch. 250–280: The Moon Burial Revelation – Chu Lingxiao confronts a reincarnated heavenly emperor, revealing that the moon holds the severed head of a cosmic tyrant from 300,000 years ago, a moment that recontextualizes the scale of William’s past battles .

Ch. 830–854: The Ultimate Punch – In the final chapters, William abandons restraint and delivers a single strike so powerful it transcends physics, symbolizing his final acceptance of his role not as a hidden sage but as the universe’s unmovable pillar .

Killer Quotes

“His life, a grand tapestry of time, had threads woven through the histories and faiths of the world.”

“For many years, William had tried to control his power to the average level of the world; he was as strong as his opponent was.”

“I’m sorry, people like you, I’ve killed no fewer than five hundred.”

Cultural Impact

The phrase “invincible in 500 years” became a viral meme template, used by fans to mock overhyped rivals in gaming and online debates .

Readers on Webnovel consistently rate the novel above 8.5/10, praising its blend of comedy and cosmic scale as a refreshing alternative to standard cultivation tropes .

Fan fiction communities have expanded on Maria and Chu Lingxiao’s backstories, turning them into iconic secondary figures despite limited canonical development .

Final Verdict

Start Here If You Want:

A protagonist whose power isn’t earned but endured—a being so ancient that gods are his former students.

A seamless blend of urban comedy and mythic grandeur, where a dinner date can segue into a meditation on the fall of Atlantis.

A completed 854-chapter journey that delivers on its premise without dragging into endless filler, offering satisfying closure .

Study If You Love:

Narratives that use immortality as a lens to examine human fragility, not just as a power fantasy.

The subversion of xianxia conventions through a Western urban setting fused with Eastern cultivation logic.

How harem structures can be repurposed to explore themes of memory, regret, and cyclical history rather than mere romantic accumulation.

Avoid If You Prefer:

Stories where the protagonist faces genuine uncertainty or vulnerability, as William’s invincibility is absolute from the outset.

Tightly paced plots without episodic, character-of-the-week encounters that dominate the mid-section.

Female characters with fully independent agency outside their connection to the immortal lead, as the narrative orbits William’s perspective exclusively.
