The person who burst out from the emergency door was Shen Yue, but he was not escaping, he was chasing someone. He watched the signal display on his mobile phone and followed the stairs, running abruptly upstairs.
The vibrant signal on the mobile phone kept flickering, at the beginning, it surged to about one-third of the signal strength and now was slowly declining.
Although the signal was weakening, the person carrying the signal should still be running to the top of the building. Shen Yue trusted his judgment, followed the signal display on his mobile phone, and rushed to the top of the hospital building in one breath.
The night wind was cool.
The rooftop was empty and seemed devoid of any human presence.
Shen Yue looked around, cautiously walked past the protruding elevator control room in front, inspected the situation there, his expression growing more serious.
