Lu Ya utilized the Jade Being to activate the Time Law, opening a passage through time, traversing past, present, and future, to return to the past to strike down Wukong's former self.
Wukong's past form was extremely weak; as long as Lu Ya returned to the era when he had just burst forth from the stone, he could easily annihilate him. However, at a critical moment, Wukong realized something. This Heavenly Mechanism Staff that could traverse time and space had been thrust by him into the temporal tunnel.
Lu Ya had already found Wukong's past form inside the temporal tunnel—it was an Intelligent Stone Monkey completely devoid of Mana.
Just as Lu Ya was about to exterminate it, a staff descended from the sky, aiming straight for his forehead.
