Li Hanyu blinked in confusion. Although she couldn't understand what they were saying, she could sense a deep bond between Professor Zuo Bai and these people, a kind of tacit understanding.
She gave them a polite smile and then turned to walk into the secret passage, forcing Zuo Bai to follow her.
The space inside the walls was suffocatingly narrow.
Rather than a passageway, it felt like a gap left by violently hollowing out the wall structure, unadorned.
The width barely allowed one person to squeeze through, and anyone slightly more built might get stuck.
All of this was fine, but what drove Zuo Bai mad was that this secret passage was obviously hastily carved; both sides were uneven, with protrusions in some places and recesses in others, completely asymmetrical.
It was truly maddening for someone with OCD.
Zuo Bai not only had OCD but also was a severe perfectionist.
He wished he could stop and, even if using his nails, smooth out the wall surface.
