"Du Cheng, Lou Haoyong." The team leader shouted into the walkie-talkie, "I'm Yan Li, the leader of the second investigation team. How's the situation on your side?"
There was no response from the other end of the walkie-talkie.
"Hello? Hello?" Mr. Yian's face suddenly turned grim, "Can you hear me? Hello? Du Cheng? Lou Haoyong?"
After a while, there was a "click" sound from the receiver, as if the walkie-talkie on the other end was picked up from the ground, and two seconds later, Wang Xiyi's voice came through: "This is 'Night Slayer', I am currently on the rooftop of building A of the Investigation Bureau, two security personnel have been confirmed dead."
The main surveillance room was immediately thrown into an uproar.
"How could this happen!?" The security personnel who had narrowly escaped looked pale, "In just a few minutes..."
...
The rooftop terrace of building A, Investigation Bureau.
