After settling Gu Li, Ling Feng arrived in Zhang He's room.
He saw that Chen Xiao and Zhang Meng were all not resting, each intently staring at their own screens.
Ling Feng stepped forward, puzzled, and asked, "What are you doing?"
"Surveillance!"
Zhang He glanced at him and simply uttered two words.
The screens displayed complex electronic diagrams that occasionally spiked, resembling an ECG, leaving Ling Feng completely baffled.
Seeing the three of them so focused, he couldn't help but ask, "Am I disturbing you? If so, should I go back and talk to you in the morning?"
Zhang He then took off his headphones and turned to look at him, "Do you need something?"
"There's something I want to discuss with you," Ling Feng nodded.
"Alright, then go ahead," Zhang He put down his headphones and stood up to go to the living room.
Ling Feng quickly relayed his situation to Zhang He.
