He Lingling was making a call to her father while stepping into the elevator. With no signal in the elevator, she said "bye" to her dad and hung up the phone.
Inside the enclosed elevator, there seemed to be a faint smell of blood lingering. There were also two drops of blood in the center of the elevator floor—not very conspicuous. He Lingling's eyes swept over them and then lifted to watch the changing numbers of the elevator display.
The weather was too cold, and she had caught a cold recently. Her nose was stuffed, and she couldn't smell much. She didn't pay attention to the bloodstains, assuming they were just some sort of stains, her mind preoccupied with what else she should buy for her dad before he arrived.
When she stepped out of the elevator, she glanced around casually and noticed some bloodstains in the hallway.
This time, He Lingling recognized them as blood, and she was momentarily stunned.
