The reason was simple, Yu Mi had figured it out, if Director Ding was really in a hurry, he would have charged up and called them down, and they likely wouldn't have escaped a scolding.
But when the group turned around, Yu Mi couldn't help but scream in shock, her gaze fixed on the end of the hallway, her body trembling like a sieve.
If it weren't for Pei Qiuyu, who was closest to her, supporting her, she would have collapsed to the ground.
"What's wrong?" Lu Ji was already extremely tense, and Yu Mi's actions made sweat break out on his forehead.
He followed Yu Mi's gaze, but apart from the dimly lit hallway, there was nothing out of the ordinary.
"You... you can't see it?" Yu Mi was almost crying out, "Don't scare me, you... can you really not see it?"
"Let's run, run!" Yu Mi, as if she had lost her mind, actually broke free from Pei Qiuyu's arm and started to dash downstairs.
