Eisen lived on the twelfth floor.
Compared to where Nell and Yoen lived, his building was relatively nice, with only eight units per floor.
In the building where Nell lived, there were thirty-four households on each floor, each crammed into a small and tight room.
Eisen's apartment number was 1208, the one at the very end of the corridor.
The building had a smart access control system. You could enter the apartment number you wished to visit, and it would automatically connect to the homeowner, who could decide whether or not to open the door based on their preset visitation rules.
Generally, the homeowner would remotely check out the visitor before deciding whether to let them in.
After He Ao entered Eisen's apartment number, the screen on the access control device in front of him flickered, displaying a dark scene.
"Who... are you?"
A husky voice slowly emerged, and something vaguely luminous appeared deep within the screen – it seemed to be an eye bloodshot with veins.
