Li Feng had just inserted the USB drive at the street corner. Before he could even do anything, the control center suddenly issued an alarm, and the red warning lights immediately flashed on.
Standing next to Li Feng, Professor Frank's face changed dramatically.
"I told you not to be too confident, the defense level here is very high."
"Let's get out of here quickly, or they will lock this place down soon." Professor Frank said, turning to leave, but found the control center's door locked shut.
"The door is locked, we're doomed now."
Professor Frank looked blankly at the locked door, and Li Feng was speechless as well. He had just inserted the USB drive and had not done anything yet. How could it trigger the firewall and even set off the alarm?
After all, he was a world-class hacker. If he could be caught so easily, then the title of world-class hacker would not be worth much.
Just then, the alarm in the base upgraded once more.
