This wasn't a question that needed answering. As soon as he said it, another wave of Mutated Plants swept through the neighborhood. Under the influence of their mental powers, the plants—which already covered the streets and buildings—gradually filled the spaces between the buildings, turning the entire area into a sea of green that was still spreading outward.
When the Mutated Plants had reached the tops of the buildings, the two men facing each other vanished from where they stood almost simultaneously.
Zheng Yuci's Spiritual World took the form of a Honeycomb, while Xu Huo's took the form of the Book Tower.
