"Three Body X: Aeon of Contemplation" written by Bao Shu, is an official fan fiction of Liu Cixin's "Remembrance of Earth's Past" series, a sequel of book 3 "Death's End", published in 2011. This is the third version cover art.
This story filled some gaps in third book, and continue from the end of it, but has a different style from the original, many web jokes in detail, and a happy ending. I heard that it is also being translated into English by Ken Liu.
If you like "The Three-Body Problem" and its two sequel,(www.amazon.com/The-Three-Body-…
) you may enjoy this fan fiction too. If you never read them, don't start form this one.
Ah, this cover art is “singer” world, a mysterious super civilization just have a few words in "Death's End". The author made further description. I made third hand settings _(:3 」∠)_
