The middle-aged man in the front looked at Huo Yulin dressed in black with his face covered. He was standing at the door of the drug research facility where all the major medicine research was done.
In an instant, he looked worried. He strode over and shouted anxiously. "Who are you?"
Two people were following behind the older man. One of them was much younger and was walking a little more slowly. When he saw the intruder, he raised his head and looked at the surveillance system and infrared sensors.
Just when the middle-aged man was approaching Huo Yulin, Huo Yao said, "15 more seconds to go before the security system comes back online. You have to handle them in 15 seconds and leave."
The moment the security system came back online, the institute security guards would find out about the intrusion. Even if he was a good martial artist, he would be outnumbered.
