This feeling was subtle.
Xu Huo had sought out Madam Butterfly to spar with her for other reasons. Creating Picture Frames by opening a door outside himself had only been an experiment, yet he hadn't expected it to work so easily. It had been far simpler than the first time he opened a door in the mental hospital.
That was why he had fully manifested his Spiritual World.
Short of being in a special environment, he couldn't enter his own Spiritual World. Madam Butterfly, however, had a way to enter hers anytime, anywhere. The circumstances and opportunities for practice weren't comparable, so he'd learned from the experience and hidden the symbol of his own spirit while manifesting the Spiritual World.
In fact, while he was manifesting the Picture Frames and doorways on a large scale, he hadn't entered that door at all. He'd hidden inside the painting. The other personality who'd entered the door and lured Madam Butterfly into the Book Tower was someone else.
He was still outside.
Although Madam Butterfly could split herself into multiple people within her Spiritual World, that seemed different from Xu Huo's multiple personalities.
After a brief hesitation, he passed through the Picture Frame five times before turning the World in the Painting into darkness. Then he took out the World in the Painting.
A new set of footsteps sounded in the darkness. Brother Tu had been running for his life in the world inside the painting for who knew how long.
When he'd first entered, he'd searched everywhere for an exit. But the Picture Frame was dark in every direction, with roads everywhere and no way out. No matter where he went, it was all the same. He couldn't use his items or Tickets, either. There was no way to escape the painting.
