She must have collected the remnants of the Little Ghost King's soul and body after killing the Ghost King, or after forcing him into the space turbulence.
Souls are hard to cultivate, but they can be devoured.
Qin Yu did what the righteous people wouldn't dare or couldn't do with ease.
She devoured it and hid it so well that even Gu Chen didn't notice.
Each hid their means, like fishing, luring the other to the best kill zone — this space tunnel.
Fearful that the other might still have a chance to survive, they must exhaust all methods and be left with no cards before revealing their trump card.
Unfortunately, Qin Yu was a step behind, yet she won this step.
Did she complete the last step?
Gu Chen was not someone who would easily admit defeat, even if he hadn't anticipated that she could not only devour the King of Zombies but also the Ghost King, nor did he expect her to master higher-level demonic rune techniques.
He chose to attack!
