"Let's go, don't stay here any longer." Zhang Zhuangzhuang grabbed Han Fei's arm and pulled him behind a few medical staff members.
Everything around seemed normal, just like any ordinary hospital, but Zhang Zhuangzhuang was as tense as if facing a great enemy, with cold sweat streaming down his forehead.
"Don't look around, if you see something you shouldn't, you won't be able to leave even if you want to." Zhang Zhuangzhuang lowered his head, his voice squeezing through his clenched teeth.
Deciding that it was better not to make a fuss, Han Fei didn't do anything out of the ordinary and followed the medical staff away from Building 4.
The medical staff walked ahead, heads lowered, not even looking at the path. They turned at the corners automatically, heading back to their respective wards, leaving only Han Fei and Zhang Zhuangzhuang to return to Building 1.
