Jiang Li doesn't know why she keeps dreaming of that apocalyptic catastrophe. Every time she wakes from the dream, her heart pounds with fear. That's why she can't help following every piece of news about the 2072 doomsday disaster. She can't explain why the dream always seems so strange, but she just can't figure out what is wrong. It isn't until she arrives in 2072, meets a man she has never seen before yet somehow already knows, and realizes that she is drawing closer and closer to the day of the apocalypse that she gradually understands: perhaps this is a prophetic dream. But when she returns to 2190, and her dreams grow clearer, she begins to doubt again. Is this really a prophetic dream? How did she end up poisoned by a toxin that disappeared more than a thousand years ago? Why did she transmigrate to a place near the tomb of Yin Han, an ancestor of the Yin clan, and nowhere else? And why can the object she brought out of the tomb connect the spaces where she and Yin Qingchen are? As the fog clears, she sees not the truth, but even deeper mysteries.
