However, just as Ling Chen and the security personnel prepared to push the door open, there was a sudden 'boom' from outside, shaking the entire building.
Beep beep beep! Beep beep beep!
With that huge explosion, a piercing alarm sounded immediately, echoing throughout the building.
The security personnel leading the way turned back at once, looked at Ling Chen, and said, "Quick, I'll send you..."
Bam!
Before the other could finish speaking, Ling Chen punched the person directly in the face, knocking out the security officer.
Phew! Ling Chen slowly exhaled a breath; Liu Dongsheng and the others had finally arrived. Having dealt with the security, Ling Chen searched him, finding a walkie-talkie and a wireless earpiece. Besides that, there was an ID card.
Ling Chen opened the restroom door, peeked outside, and saw several security personnel running along the spacious corridors, each wearing a panicked expression.
