The "patients" entering the Jinglin Sanatorium are influenced solely by the sanatorium's rules—this simple statement made Yu Sheng almost instantly consider a possible scenario.
"...That independent investigator named 'Sun Chen', is it possible he's using the 'rules' of Jinglin Sanatorium to avoid the influence of that 'Tower'?"
"That's what I guessed too," Little Red Riding Hood nodded, "After all, he had previously posted about being persistently entangled by that Tower, even suspecting that part of his mind was trapped in nightmares related to the Tower. In this situation, he's certainly sought help from familiar exotic doctors and spiritual ability users, and possibly even from the Special Service Bureau. Hiding in Jinglin Sanatorium might be advice given by someone."
Yu Sheng recalled his previous experiences exploring the "Dark Alley" with Little Red Riding Hood and the King, remembering the "eroded" old bookstore and his bizarre, chaotic dreamscape at dawn.
