"What's going on?" Hearing the unusual noise, the four men in black outside the elevator tensed up, looking around warily.
Bang bang bang bang!
But soon after came a series of dull thuds. Ye Luo silently circled behind the four men, and before they could react, he knocked them out, then pressed the elevator button and stepped inside.
Meanwhile, in the surveillance room of Han Group's building, the security guards noticed several monitors going dark. They quickly grabbed their walkie-talkies and called out, "There's a situation in the underground parking lot, send someone to check immediately."
The elevator quickly ascended to the second floor. As soon as the doors opened, a group of security guards armed with stun batons charged in.
"You..."
The guards barely got a word out before Ye Luo took them down with lightning-fast speed, then he quickly headed towards a certain location.
