After 3:44 AM, the building was indeed different; Han Fei had triggered two F-rank hidden missions in a very short time, which was telling.
Patrolling and running to room 1244 seemed like very simple tasks at first glance, but the simpler the task, the more Han Fei worried. He was acutely aware of the difficulty of F-rank missions.
The simpler the task appeared, the more trouble one might encounter in completing it.
"She's coming after us!"
Han Fei clenched his teeth; the woman who had fallen from the floors above would kill all "things" she saw. She was methodically making her way up, and the only way to break this pattern was by going to room 1244.
Room 1244 was one of the three most dangerous rooms in building one, but Han Fei had no other choice but to run there!
Only by completing the mission could he exit the game. For someone who might not even see tomorrow, staying alive was the most crucial thing.
