The Redemption of Time is a fanfiction webnovel written by Li Jun under his Baoshu pseudonym, which literally means divine tree. It was originally posted online less than a month after Death's End was published as Three Body X: Aeon of Contemplation. It's not officially canon, but it was approved by Cixin Liu and published by the same publisher. This is the first novel length work of fanfiction that I've read. It definitely reads like it is. If you have high expectations, you may want to reconsider them.

This book is in many ways an apologia, a formal defense of Death's End, primarily told through Yun Tianming's perspective, though various other perspectives are used as well. It's not only that it provides additional explanations for several events, it's specifically ones that I believed to be idiotic or glossed over. That leads me to assume that a significant number of others thought they were as well, hence the need for providing additional detail so that what happened seems more reasonable and rational. I can appreciate a fan's dedication to an author, but I would've really preferred there to be more narrative rather than scene after scene telling me why I should've trusted that whatever was offpage was amazing and had faith that the author knew what he was doing.

Speaking of faith, I was surprised by how much Christianity was included in here. It's certainly a different take on heaven, angels, eden, God, and satan. I don't know how literally versus metaphorically it's meant to be taken considering how explicitly everything is presented, including bible verses. Other religions are mentioned in passing, but the focus is on Christianity. Li Jun attended a Catholic university in Belgium for a philosophy degree, but I didn't know that until after I finished reading.

What amused me the most were the anime references, especially citing the Endless Eight episodes of The Melancholy of Haruhi Suzumiya anime as justification for his actions. The Legend of the Galactic Heroes epigraph was nice as well. There's also various literary references, which are around as common as referencing the same Japanese porn star over and over. The ending is a metafictional display of admiration, which I found to be entirely silly, but it's not terrible.

This novel was published in English in 2019, which means that his later written short fiction was translated and published in English before this novel was. "What Has Passed Shall in Kinder Light Appear" is a great story and it was the first story I read from him. Unfortunately, everything afterwards has been disappointing. I read it mostly for the sake of completion, but also because I thought there would be a chance it could be decent. There doesn't seem to be any reason to me to read it other than for a perhaps misguided sense of completion or simply because anything more suffices.
