The wall had retreated only a tiny distance. If Yu Sheng hadn't been staring at it the whole time, he probably wouldn't have noticed the change at once—but he was certain he hadn't imagined it.
The wall was retreating.
After standing stunned for a moment, Yu Sheng raised his hand and tried moving closer to the wall again.
The wall retreated once more, and this time by an even greater distance than before—even Zheng Zhi noticed the abnormality at a glance.
"Brother Yu, this thing... something's not right!" The young Special Operations Bureau agent—who hadn't even become a full-fledged member yet—stared blankly at the tall wall, visibly growing tense. "The wall's moving backward!"
That was enough to keep Little Red Riding Hood, Luna, and Huli from waiting in the back. Several of them squeezed into the narrow gap between the two buildings, and under their many watchful eyes, Yu Sheng conducted another "test." The tall wall leading to Dark Alley shrank back another few centimeters.
After nearly half a minute of silence, Yu Sheng finally turned around and looked at Little Red Riding Hood behind him. "...Has this ever happened before?"
"How could it have?!" Little Red Riding Hood's eyes widened as she stared at Yu Sheng as though he were a ghost. "How can you scare an Otherworld into shutting its doors...?"
"How could I have scared it?!" Yu Sheng immediately became even more flustered at the expired JK's complaint. "It's not like I've even done anything to it yet. And even if I really was responsible for the collapse of the Old Bookstore last time, an Otherworld shouldn't react like this, should it?"
As he spoke, he heard a faint rustling sound from beside him. He turned his head instinctively and saw the wall retreat another few centimeters
