9:14 PM, evening.
Fengling took three pills for the fifth time and walked into the security passage under the astonished gaze of the janitor.
As Fengling's figure disappeared to the other side of the door, he rubbed his eyes vigorously and took out his phone to check the time once more.
9:15 PM.
Time was passing normally, which meant he had not fallen into the so-called "time loop" that had been trending online. It was simply that this young lady had to go down the security passage every fifteen minutes.
As Fengling descended the stairs, she muttered firmly, "Stop on the third floor, then take a breath and continue down to the fifth floor..."
Her attempt failed once again.
She had not stumbled into the dreaded "contaminated corridor." When she pushed the door open, the security guard stared at her with the same astonishment as the janitor.
Fengling also stared back at the security guard for a long moment.
