The Biggest Regret of Three-Body
Death's End left an enormous narrative gap: what exactly did Yun Tianming experience in the Trisolaran world?
He was sent out via the Staircase Program, his brain captured and revived by Trisolarans. He lived alone in their world for decades, encoding the secrets of lightspeed ships, curvature propulsion, and dark domains in three fairy tales. But the details — how he was revived, his role in Trisolaran society, how he crafted those fairy tales — are completely blank in the original.
Liu Cixin didn't forget to write them. He left them on purpose.
At the 2011 Hong Kong Book Fair, he said something that broke every Three-Body fan's heart:
"Obviously the biggest gap, the easiest gap to fill, is Yun Tianming's main storyline. I was inexperienced then, so I saved it to write as a parallel novel later. But now I can't write it anymore."
Why? Because just months after Death's End was published, a fan named Baoshu wrote The Redemption of Time in three weeks and filled that gap.
Three Weeks vs. "The Rest of His Life"
The Redemption of Time started as online fan fiction in late 2010 and was formally published by Chongqing Press in 2011 — becoming the only Three-Body sequel published with Liu Cixin's "allowance." Ken Liu translated it into English for Tor Books in 2019.
Baoshu wrote it in three weeks.
Liu Cixin had planned to spend "the rest of his career" on Yun Tianming's story.
Three weeks won.
What Does Liu Cixin Actually Think?
His attitude is exquisitely nuanced — restrained in public, candid in private.
In one interview:
"Honestly, I really don't want other people writing sequels to my novels. Some authors wrote what I wanted to write — doesn't that just block my path?"
At the 2011 Hong Kong Book Fair, more directly:
"I can say with certainty that no author, Chinese or foreign, likes fan fiction. Why? Because it blocks the path for the rest of your life. It builds a wall in front of you that you can't walk through."
"I don't want to see too many fan works. Of course, I can't stop them from writing, and I allowed publication. But asking me to write a preface or recommendation — that's a bit... a bit much. Let's leave it at that."
Key signals:
- "Blocks the rest of your life" — not politeness, real creative anguish
- "Allowed publication" — not "endorsed," not "recommended," just "allowed"
- "Writing a preface is a bit much" — he won't even stand behind it
- Neither publisher nor Wikipedia confirms any "official canon" status
A Reader's Honest Experience
I'll be blunt: I opened The Redemption of Time, read the first chapter, and put it down.
Not because Baoshu writes "badly." Because the flavor is wrong.
Liu Cixin's core quality is coldness — he describes civilizational rise and fall with an engineer's precision, writes human insignificance in the language of physics. This coldness isn't apathy; it's the calm of someone who has seen the universe's true nature. You finish reading and feel small, but there's a strange dignity in that smallness.
The Redemption of Time mimics this quality, but it mimics the form, not the substance. It has grand settings, complex concepts, cross-timeline narrative — but it lacks Liu's unique "engineer looking at the world" perspective. It reads like a clever humanities student doing Three-Body fan fiction, not a physicist-intuitive mind building a world.
Reviews of The Redemption of Time are genuinely polarized — fans say it fills the trilogy's biggest gap; critics say it overwrites carefully crafted ambiguity with questionable completion.
The Eternal Dilemma of Fan Fiction
The Redemption of Time controversy points to a deeper question: who has the right to continue a story?
Legally, Liu Cixin owns the rights and "allowed" publication. But creatively, once fan fiction fills the gap an original author left, the author loses the freedom to create in that direction — not legal restriction, but psychological. You can't write "Yun Tianming's story in the Trisolaran world" anymore, because readers will inevitably compare your version to the one that already exists.
Liu Cixin put it clearly: "It builds a wall in front of you."
That wall will never come down.
Will There Ever Be a Three-Body Sequel?
By Liu Cixin's own account: no. At least not Yun Tianming's story.
But the Three-Body universe has other unexplored directions — the Ball Lightning technological inheritance, the Singer civilization's full scope, the physics of dimensional strikes, the Dark Forest theory playing out in other star systems. The Redemption of Time didn't touch these areas.
But will he write them? Liu Cixin has produced almost no new long-form fiction in recent years, focusing instead on supervising screen adaptations — Netflix and Tencent.
Perhaps for him, the Three-Body story is finished. Not forced to end by The Redemption of Time, but naturally reaching the end of a creative journey.
But that "parallel novel" about Yun Tianming — the story he saved for "the rest of his career" — we will never read it.
