Bab 399: Chapter 399: The Game Within the Spiritual World

"Materialized Library, your Spiritual World is quite impressive," Madame Butterfly casually surveyed the stacked floors and bookshelves. Turning to speak with Xu Huo, she found that where his voice had come from just a moment ago was now empty, a door on a nearby floor had just closed.

She didn't pay much attention to the person who had disappeared in an instant. Instead, she reached out her hand in the air, and a giant zipper appeared out of nowhere. She walked through it and arrived at the adjacent floor, opening the nearest door with ease.

Xu Huo's Spiritual World was a cylindrical tower-like library, with a count of floors that was difficult to determine. Each floor was filled with bookshelves, forming a giant ring. Every so often, a space equal to the width of a door was left empty, but what lay behind these doors could not be seen from the outside.
