Dark silhouettes ran, Zhou Yi chased.
Both parties bore an aura around them, which made recognition unimpaired in the darkness.
As they moved, the whole world also slowly turned, gradually shrinking into a double-helix structure of black and white colors, endlessly extending into the distance.
Zhou Yi and the shadow sprinted on this gigantic DNA-like surface.
Oddly, Zhou Yi found that when he ran on one side, he felt stable and could move forward quickly. But if he switched to the other spiral side, he experienced strange lags and distractions as if he didn't match the road on that side, which led to him being pulled farther away.
Both moved on their respective paths, like two parallel lines that could never intersect.
The shadow taunted ahead, "Even though I don't know why you can retain your self-consciousness, even if we coexist, you can't eliminate me. Now you are me, I am you, we share one body!"
