After returning to the Heart Space, Laplace glanced at Angel and said softly, "You really are cautious. But this is good too. To some extent, it prevents intruders from entering the Heart Space through the Mirror Passage."
Angel: "I didn't think that much, I just felt that opening a door in that place wasn't very appropriate."
Half a minute ago, just as Angel was preparing to leave the Buffer Zone, he did two things. The first was to leave the Wish Book and the gemstone teapot in the Buffer Zone—after all, the Buffer Zone could also serve as a temporary storage vault; the second was to set up an Illusion Technique at the entrance between the Buffer Zone and the Mirror Passage.
If one looked from within the Buffer Zone at this moment, they would discover that the entire Buffer Zone now had only a single door left. That was the Mirror Gate of the Cha Cha Mirror leading into the Buffer Zone.
All the other entrances and exits had disappeared.
