Chen Xiaodao, a modern history graduate student who accidentally traveled back in time to the Jiajing period of the Ming Dynasty, woke up to find that he had become a small flag officer of the Jinyiwei, and also got into trouble with the powerful Yan Song and his son. What's even more bizarre is that a mysterious woman who calls herself Liu Rushi tells him that she deliberately summoned him from the 21st century, because only he can prevent a catastrophe that is about to destroy the Ming Dynasty.
However, as Chen Xiaodao investigates further, he discovers that Liu Rushi's identity is far from simple as she appears - the strange scar on her wrist can release the key code and rewrite reality; and the "blue pupil" in his own left eye can actually glimpse fragments of the future. The two gradually uncovered a shocking conspiracy that spanned the Ming Dynasty, the Qin Dynasty, and the 23rd century: the "Guixu" **, an ancient existence that swallowed up time and space, is trying to completely obliterate human civilization by tampering with history.
When the quantized Jin Yiwei meets the strange woman with the key code, can they find each other in countless parallel times and spaces to prevent the end of the world?
